The Pacific War - week by week

- 178 - Pacific War Podcast - The First Okinawa Counteroffensive - April 15 - 22 - , 1945

Last time we spoke about Yamato’s Last Stand. In the spring of 1945, as WW2 intensified, the US Marines commenced a fierce assault on Okinawa. Amidst heavy bombardment, the Japanese 32nd Army fortified their positions, preparing for a desperate counteroffensive. Codenamed Operation Ten-Ichi-Go, Japan's final bid involved the legendary battleship Yamato, tasked with a suicidal mission to confront the American fleet. On April 7, 1945, as the Yamato sailed towards its fate, American forces were ready. Hundreds of aircraft descended upon the ship in a coordinated attack, unleashing bombs and torpedoes. Despite its infamous firepower, Yamato struggled against the relentless onslaught. With its systems failing, Captain Aruga and Admiral Ito made the agonizing decision to go down with their ship. As the proud battleship sank, it symbolized both Japan's indomitable spirit and the crushing weight of defeat, forever etching its story into the annals of military history.

Picking up from last time. The Japanese naval-air counteroffensive against Admiral Spruance’s forces at Okinawa had been decisively defeated with minimal losses, allowing General Buckner’s 10th Army to proceed with the land offensive largely without interference. While General Geiger’s Marines advanced toward the sparse Japanese defenses in northern Okinawa, General Hodge’s 24th Corps in the south encountered the main enemy line of resistance centered around the Shuri fortified zone. Initially, the 32nd Army had declined to launch a land counteroffensive in conjunction with Operation Ten-Go and the Yamato’s suicide attack, fearing that the Americans might execute another amphibious landing at Machinato while the Japanese wasted their strength in a futile effort to reclaim the airfields. However, pressure from Tokyo and Formosa compelled General Ushijima to resume planning for this operation. Ultimately, it was decided that instead of initiating a broad counterattack, the Japanese would deploy a brigade-strength force overnight on April 12 to breach the American lines and advance approximately six miles. If successful, this would be followed by a general attack. Accordingly, Colonel Yoshida Masaru’s 22nd Regiment was assigned to the 62nd Division and assembled northeast of Shuri, tasked with attacking through enemy lines east of the Ginowan Road and advancing toward Shimabuku. To bolster this offensive, General Fujioka was also instructed to deploy three reserve battalions for a three-pronged attack from the west aimed at Chatan. However, Colonel Yahara, 32nd Army operations chief, strongly opposed the counterattack plan, feeling that it was not in keeping with the army's defensive mission and that it would waste men. He succeeded in getting the 1st Battalion of the 22d Regiment and elements of the 23d IIB cut from the counterattack force. He made a dire prediction that the infiltrating units, unfamiliar with the terrain in their attack sectors, would get lost, confused, and cut to pieces during a night assault. Taking a sidenote here, I read Yahara’s rather famous novel about his experience of the battle for Okinawa and I highly recommend it to all of you. It's a great insight into the perspective of the Japanese and how the leadership were beginning to change their mind on how to go about the war. Yahara, acting without Ushijima's knowledge, advised Fujioka to commit only four battalions to the attack, predicting it would inevitably fail.

Meanwhile, the American offensive was still in progress. On April 9, as Major-General George Griner’s 27th Division landed at the Orange Beaches near Kadena, the ships of Colonel Waltern Winn’s 105th Regiment met with Admiral Blandy’s Eastern Islands Attack and Fire Support Group at the Kerama Islands, preparing to move to Tsugen Island overnight. Following a preliminary air and naval bombardment, which saw some Japanese mortar fire in response, Winn’s 3rd Battalion successfully landed on the morning of April 10. The Americans then advanced inland with light resistance, quickly securing the northern part of the island but failing to overrun the entrenched enemy positions in Tsugen village. The assault continued the next day against persistent opposition, but organized resistance gradually diminished, allowing the Americans to secure the rest of the island by nightfall, marking the conclusion of the Eastern Islands operation. On April 11, General Shepherd’s Marines continued to probe for the main enemy positions in northern Okinawa; the 1st Battalion, 22nd Marines patrolled eastward from their new base at Shana Wan, while the 29th Marines advanced toward Manna. Due to this progress, Buckner decided to fully merge Phases I and II, ordering the 77th Division to capture Iejima on April 16. To the south, Colonel Albert Stebbins’s 106th Regiment was attached to the 96th Division, moving toward that division's reserve area, while Colonel Gerard Kelley’s 165th Regiment relieved the 17th Regiment in the corps service area. Most significantly, General Bradley continued his attacks on Kakazu Ridge, with the 1st Battalion, 381st Regiment attempting to assault the western slopes but halted short of the ridge crest by determined defenders. At the same time, the 3rd Battalion, 383rd Regiment pushed up the northwest slopes of Kakazu Ridge but was also pinned down by intense Japanese fire.

Simultaneously, following an intense artillery bombardment, the 1st Battalion of the 32nd Regiment finally succeeded in breaking into Ouki. However, additional reinforcements were thwarted by heavy Japanese fire, forcing the troops to retreat. With no further advancements, the 7th Division and the 382nd Regiment were relegated to patrolling and mopping up their designated areas over the next few days. At sea, Admiral Ugaki resumed his kamikaze assaults that day, damaging the carriers Essex and Enterprise, the battleship Missouri, and eight destroyers. However, his primary operation commenced on April 12, when he launched approximately 380 aircraft for a second mass Kikisui attack, primarily targeting Admiral Turner’s Task Force 51 west of Okinawa. Thanks to cryptanalysis warnings, Turner scrambled his own fighter planes, which successfully shot down 298 Japanese aircraft. Despite attempting numerous missions, Kanoya’s specially trained 721st Kokutai Jinrai-Butai “Divine Thunder” unit had so far failed to launch a single Ohka suicide rocket against the Americans. On April 12, however, eight Betty bombers would finally launch six Ohkas against the 5th Fleet, although five Betties never returned. At RPS-14, about 70nm northwest of Okinawa, a Zero plowed into Mannert L. Abele’s engine room at 14:40, its 500lb bomb exploding and leaving the destroyer dead in the water. One minute later an Ohka came screaming in at 575mph, slammed into Mannert L. Abele and exploded. She sank in five minutes, losing 97 dead. Mannert L. Abele was the first destroyer hit by an Ohka and the last sunk by one. Destroyer-minesweeper Jeffers, en route to assist Mannert L. Abele, observed a twin-engined bomber eight miles away drop a smoking “belly tank” that suddenly rocketed towards Jeffers “at terrific speed.” Numerous 40mm hits and hard maneuvering saw the Ohka miss Jeffers astern and disintegrate. Additionally 3 battleships, 14 destroyers, 2 destroyer minesweepers, and another landing craft were damaged. Meanwhile, Admiral Rawlings’ Task Force 57 was ordered to strike the Shinchiku and Matsuyama airfields in northern Formosa, and over the next two days, 48 Avengers and 40 fighters successfully attacked Shinchiku and Kiirun Harbor. On Okinawa, the 6th Reconnaissance Company captured Bise Saki with minimal resistance, while the 29th Marines faced significant opposition southeast of Manna near Mount Yae-Take, indicating where the main enemy forces were located. This prompted Shepherd to reposition the 3rd Battalion, 22nd Marines to Awa as his new divisional reserve. At the same time, Japanese guerrillas managed to retake Ishikawa, which they would hold for the following two days.

Facing south, the 96th Division made another attempt to capture Kakazu but was once again thwarted by the determined defenders. By this time, approximately 5,750 Japanese soldiers were estimated to have been killed in the southern region, while the 24th Corps suffered losses of 451 men killed, 2,198 wounded, and 241 missing. In the afternoon of April 12, 1945, in Warm Springs, Georgia, while sitting for a portrait by Elizabeth Shoumatoff, President Franklin D. Roosevelt said: "I have a terrific headache." He then slumped forward in his chair, unconscious, and was carried into his bedroom. The president's attending cardiologist, Howard Bruenn, diagnosed a massive intracerebral hemorrhage. At 3:35 pm, Roosevelt died at the age of 63. His declining health had been kept secret from the public, leading to shock and sorrow worldwide upon the news of his death. Harry Truman, who was serving as vice president in 1945, succeeded FDR as president. Meanwhile, back in Okinawa, Fujioka initiated his counteroffensive after a heavy artillery bombardment, advancing his four battalions to secretly infiltrate the American lines. On the eastern front, the 22nd Regiment struggled to advance due to becoming disoriented in unfamiliar terrain. 

The night attacks suffered from several unexpected problems. Heavy shelling had changed the landscape, blasting away villages and thickets, so that even though night infiltrators knew their maps and thought they knew the terrain, they lacked the landmarks needed to tell them where they actually were. Moreover, frequent illumination shells forced the eyes of night infiltrators to adjust so many times that their capacity to adjust was lost. They became temporarily blinded and so were unable to move. Because of the unfamiliar terrain and flash blindness, the Japanese night fighters had difficulty reaching their assigned objectives. In fact, it was hard for them to reach their jumping-off points. Continuous naval bombardment of crossroads and bridges forced units to rush across in small groups between shells so that the units became strung out on the roads and difficult to control. It was hard to move heavy ammunition and supplies forward because of these interdiction points and the generally churned up roads. Even when units reached their northward assembly points safely by night, they were immediately exposed to aerial observation and artillery fire at dawn, since they lacked enough time to dig in. Units that attacked across American lines safely in darkness had the same problem: they lacked time to dig in and so were utterly exposed to artillery fire at morning light. Night attacks, like flanking maneuvers, were a kind of cure-all in prewar Japanese doctrine. But they failed to provide the expeditious results on Okinawa that IJA doctrine had led the 32d Army Staff to expect.

Consequently, Yoshida’s four infiltration attempts, each involving about a squad, were effectively repelled by troops from the 32nd, 184th, and 382nd Regiments before midnight. The only significant attack came from around 45 Japanese soldiers against the positions held by Company G of the 184th, which quickly returned fire, forcing the enemy to retreat to their caves and trenches. In contrast, the assault on the 96th Division on the western front was intense, sustained, and well-coordinated. The forward units of Major-General Nakajima Tokutaro’s 63rd Brigade launched their own local offensive to maintain pressure on the thin line held by the 382nd and 383rd Regiments, while elements from the 23rd, 272nd, and 273rd Independent Battalions infiltrated the American lines and moved into the Ginowan area.

The majority of the 272nd Division launched an assault on American positions at Kakazu Ridge, enduring intense naval and artillery fire but ultimately being repelled by the determined defenders after several hours of combat. By morning, the bodies of 317 enemy soldiers were counted on the ridge, whereas the Americans suffered 50 casualties. Meanwhile, the 273rd Division attacked along the west coast against the recently arrived 2nd Battalion of the 106th Regiment, which decisively repelled the Japanese assault and nearly annihilated the independent battalion. Despite this, some units from the 23rd and 272nd Independent Battalions managed to penetrate approximately 1,000 yards behind American lines between Nishibaru and Kaniku but became isolated after dawn on April 13. Throughout the day, Bradley's troops worked to eliminate these infiltrators, many of whom detonated explosives when trapped. When these units retreated into Japanese lines later that night, only half of their original numbers had survived. Just before midnight, the reserve 9th Company of the 22nd Regiment launched an attack against the 184th Regiment following preparatory artillery fire, but this offensive was quickly disrupted by artillery, mortars, and machine-gun fire. On April 14, Nakajima’s forces attempted two more assaults on Kakazu in the early hours, but these attempts were similarly thwarted by artillery and machine-gun fire. Given the failures of the offensives, Ushijima had no choice but to order a suspension of the attack, resulting in a shift to a defensive posture for the Japanese. Over the two days of combat, the 24th Corps reported killing 1,594 Japanese soldiers and capturing four, with losses of fewer than 100 American troops.

In the northern region, an extensive air and naval bombardment of Iejima commenced while the Fleet Marine Force Amphibious Reconnaissance Battalion landed on Minna Island, securing it without encountering resistance to position artillery units for General Bruce’s upcoming attack, which would involve the 305th and 306th Regiments. Meanwhile, in northern Okinawa, the 29th Marines continued to advance against enemy positions at Yae-Take through vigorous patrolling, preparing for a morning assault the next day. Concerned about the pace of progress, Shepherd relieved Colonel Bleasdale of command, replacing him with veteran Colonel William Whaling. However, Shepherd recognized that taking the 1,200-foot summit would require more than one regiment, so he ordered the 4th Marines to move from the east coast to Yofuke and then to the southwest corner of the Motobu Peninsula. Additionally, Colonel Shapley’s 3rd Battalion was tasked with moving to Kawada, while the reinforced 2nd Battalion of the 22nd Marines rapidly advanced up the west coast to secure Hedo Misaki. On April 14, Shepherd initiated a coordinated assault on Yae-Take, with Whaling’s 3rd Battalion and Shapley’s 2nd Battalion advancing from the area around Toguchi against unexpectedly light resistance, while the rest of the 29th Marines moved out from Itomi to clear the Itomi-Toguchi Road. Although the eastern front faced strong opposition and required a change in strategy to advance southwesterly for better elevation advantage, rapid progress was made on the west, prompting Shapley to commit his reserve 1st Battalion to secure the exposed right flank.

At the same time, Whaling’s 3rd Battalion and Shapley’s 2nd Battalion continued their advance against significantly strengthened enemy resistance, ultimately capturing another ridge located 1,000 yards ahead. Initial opposition consisted of small enemy groups. These hostile covering forces employed every available means to delay and disorganize the advance, and to mislead the attackers as to the location of the battle position. The Japanese would lie in concealment, with weapons zeroed in on a portion of a trail, allowing a considerable number of Marines to pass before opening up on a choice target. An entire platoon was permitted to pass a point on a trail without interference, but when the company commander reached that point with his headquarters section, a burst of machine-gun fire killed him and several others. Officer casualties were excessively high. In an area in which there had been no firing for over half an hour, Major Bernard W. Green, commanding the 1st Battalion, 4th Marines, was killed instantly by machine-gun fire. No one else was hurt, although Major Green was standing with his operations and intelligence officers on either side of him. Lieutenant Colonel Fred D. Beans, Regimental Executive Officer, assumed command of the battalion. "It was like fighting a phantom enemy." For while the hills and ravines were apparently swarming with Japanese, it was difficult to close with them. The small enemy groups, usually built around a heavy Hotchkiss machine gun augmented by Nambus, would frequently change positions in the dense vegetation. Hostile volleys elicited furious Marine fusillades into the area from whence the firing had come. But after laboriously working their way to the spot, the Marines came upon only an occasional bloodstain on the ground. Neither live nor dead Japanese were to be found. One Marine registered his impression of these tactics by blurting out, "Jeez, they've all got Nambus, but where are they?"

Meanwhile, the 29th Marines advanced 800 yards up steep slopes despite facing fierce opposition; however, the 1st Battalion eventually found itself pinned down by intense Japanese gunfire. Additionally, Shapley’s 3rd Battalion crossed the island via motor march to relieve the 3rd Battalion of the 22nd Marines in division reserve, which then returned to its patrol base at Majiya. To the south, Hodge recognized the need for a full-scale effort to penetrate the fortified Shuri area, so he scheduled a corps attack involving three divisions abreast for April 19. In preparation, he dedicated the following four days to organizing the assault, with the 27th Division taking over from the 96th Division in the western region of its zone, while smaller local attacks were conducted to enhance forward positions. Aware of the impending major attack, the Japanese used this preparatory period to bolster their defenses with additional supporting weapons. Back to the north, on April 15, most of the 29th Marines consolidated their defenses on high ground and exerted constant pressure on the rear of the Yae-Take position through vigorous patrols to the west and northwest. On the other hand, Whaling’s 3rd Battalion advanced east and south approximately 900 yards amidst heavy machine-gun, mortar, and artillery fire before being halted by a strong enemy position on Hill 210. Additionally, the 4th Marines faced fierce resistance as Shapley’s battalions finally secured Hill 200 and a critical hill mass just southwest of Yae-Take.

Fully aware that his primary positions would soon be overrun, Colonel Udo decided to transition to guerrilla tactics by nightfall, relocating his command to the mountainous regions of northern Okinawa via Itomi. In light of these developments, the 1st Battalion, 22nd Marines was placed into division reserve at Awa to allow Shapley’s 3rd Battalion to prepare for the following day’s assault. On April 16, the offensive resumed, with Whaling’s 3rd Battalion swiftly capturing Hill 210 in conjunction with Shapley’s 2nd Battalion. Meanwhile, the rest of the 4th Marines secured a ridge just below Yae-Take by midday, while the 29th Marines applied continuous pressure on the rear of Udo’s fortified stronghold.

While the 4th Marines was storming the fortified position on Yae-Take, the 29th Marines maintained relentless pressure against its rear. The opposition which faced the 29th was similar to that on the front of the 4th. From log-revetted bunkers and occasional concrete emplacements the enemy resisted the advance with increasing stubbornness, supported by machine-guns, mortars, and artillery concealed in ravines and in caves on the high ground. Rugged terrain and an acute supply situation also contributed to the difficulties confronting the 29th Marines in accomplishing its task of clearing the high ground flanking the Itomi-Toguchi Road. The enemy displayed his usual ability to exploit the terrain and derived the maximum benefit from his weapons emplaced in caves and pits and concealed by natural cover. Particularly noteworthy was his use of 20mm dual-purpose cannon against personnel. Fire from these weapons on battalion CPs was a daily occurrence. All roads and natural avenues of approach were covered. Any attempt to move over the easier routes was met with bitter and effective resistance. Consequently, "the method of reducing the enemy positions followed a pattern of 'ridgehopping'," covered by the fires of all supporting weapons. This tactic enabled the attacker to envelop the hostile defenses and reduce them in detail. Numerous abandoned positions and weapons encountered by the 29th indicated that the determination of the Japanese to resist diminished considerably when they were taken from the flank. In contrast to a coordinated advance with all units in contact across a broad front, the action in the zone of the 29th Marines was characterized by attacks that, even when delivered simultaneously, constituted a series of local patrol actions to seize critical positions, followed by mopping up activity within the area.

In the afternoon, Shapley’s 1st and 3rd Battalions assaulted the formidable mountain, gradually making their way up the steep slope under light and scattered small-arms fire. However, as the Marines reached the peak, they encountered intense fire at close range, which quickly forced them to pull back. After a fierce and close engagement, the 1st Battalion ultimately regained control of Yae-Take, managing to hold the summit against strong Japanese counterattacks, aided by artillery support and Shapley’s 2nd Battalion. Meanwhile, at dawn on April 16, two battleships, four cruisers, and seven destroyers under Rear-Admiral Bertram Rodgers launched a heavy bombardment on Iejima, while aircraft bombed and rocketed the island, dropping tanks of napalm on and behind the beaches.

Approximately 2,000 Japanese troops, led by Major Igawa Masashi, had destroyed Iejima’s airfields and strengthened the central eastern region of the island in an effort to entice the invaders to approach the vulnerable southeastern beaches. Their aim was to annihilate them with concentrated fire from numerous hidden positions in the Pinnacle and the town of Ie. However, the Americans saw through this strategy. Bruce’s plan involved landing Lieutenant-Colonel Joseph Coolidge’s 305th Regiment on the Red Beaches along the southern coast of Iejima and Colonel Aubrey Smith’s 306th Regiment on the Green Beach at the island’s southwest tip. The 305th was tasked with advancing eastward to capture additional landing areas, while the 306th was to move north and take control of the airfield. Both regiments would then focus on neutralizing enemy strongholds at the island's eastern end. Following intense air and naval bombardments, amphibious tanks and subsequent waves of amphibious tractors surged toward the landing beaches that morning, supported by rocket fire from LCI gunboats. At 07:58, the forward elements of the 1st Battalion, 305th Regiment successfully landed on the southern coast of Iejima, just south of the airfield, while the 3rd Battalion landed on a different beach, 600 yards to the left, three minutes later. At 08:07, the first waves of the 306th Regiment made landfall on Green Beach. The 305th moved swiftly inland over high dunes and then turned east toward Ie, while the 306th advanced 2,000 yards inland to the airfield's western edge, with the reserve 3rd Battalion securing the island’s western end. By the afternoon, the troops advanced rapidly, seizing the airfield with only light resistance, achieving a total gain of about 5,500 yards by nightfall. Conversely, the 305th faced stiffer opposition on its way to Ie, managing to advance only about 800 yards eastward while defending against strong nighttime counterattacks.

During the night of 16 April the enemy launched a coordinated attack on the 3d Battalion of the 305th. The attack came with suicidal recklessness. The Japanese were supported by mortars and 70-mm. guns, and were armed with small arms, sharpened stakes, bags of hand grenades, and literally hundreds of satchel charges, some of which had been improvised from mortar shells. Japanese worked up to the perimeters in small groups and either threw their satchel charges at close range or blew themselves up in an effort to take Americans with them. Some of the human bombs were successful, but most of the Japanese were killed before they came within effective range. One American had his arm broken by the flying leg of a Japanese soldier who had blown himself up. After hours of wild fighting in the dark the enemy withdrew, leaving 152 of his dead in and around the 3d Battalion's position. 

While back at sea, Admiral Mitscher’s Task Force 58 had effectively launched attacks on Amami Oshima, Tokunoshima, Kikaijima, and southern Kyushu over the past four days, the Japanese responded with a series of scattered kamikaze assaults that caused damage to the battleship New York and four destroyers. On April 16, Ugaki initiated his third large-scale Kikisui attack, acutely aware that another failure in the air could spell the doom of Operation Ten-Go. Despite Mitscher's preemptive strikes against Kyushu, where Americans claimed to have destroyed 202 aircraft and damaged 79 at the cost of only nine planes, at least 289 Japanese attackers were still able to launch missions against Spruance’s 5th Fleet. Although American interceptors and anti-aircraft fire recorded another 217 kills, the surviving kamikaze pilots managed to sink the destroyer Pringle and inflict damage on the carrier Intrepid, the battleship Missouri, three destroyers, two destroyer minesweepers, and two landing craft. Notably, the destroyer Laffey withstood six kamikaze impacts, four bomb hits, and numerous strafing runs, resulting in 32 fatalities and 71 injuries among its crew. The following day, a smaller attack on April 17 resulted in additional damage to the light carrier Bataan and one destroyer, yet Americans claimed another 49 kills. However, Ugaki had exhausted much of his strength since the invasion began and was left with approximately 598 operational planes. Meanwhile, fighting continued in northern Okinawa, where some surviving troops from Udo advanced toward Nakaoshi to escape the Motobu Peninsula. Supported by heavy artillery barrages and battleship gunfire, the 29th Marines slowly progressed over challenging terrain, encountering only light resistance, as they successfully secured the mountainous area ahead and connected with the 4th Marines.

Shapley’s 1st and 3rd Battalions continued their push northward toward the Itomi-Toguchi Road, swiftly advancing downhill and completely overwhelming all Japanese defenses in the region. By nightfall, the 4th and 29th Marines had positioned themselves along the elevated terrain overlooking the Itomi-Toguchi Road. The 305th resumed its assault, aiming to capture the high ground behind Red Beaches 3 and 4. The 1st Battalion encountered only minimal resistance along the coast, allowing them to make significant progress, while the 3rd Battalion quickly secured the high ground in its area before being halted by intense machine-gun fire from caves in the coral slopes to the north. A maneuvering strategy followed by an infantry-tank assault eventually neutralized this enemy position, enabling the advance to continue steadily until the 3rd Battalion reached the outskirts of Ie. Due to the strong resistance faced, Bruce opted to deploy Colonel Stephen Hamilton's 307th Regiment on the beaches southwest of Ie. The 2nd and 3rd Battalions were subsequently landed there and launched an attack northeast, quickly advancing approximately 400 yards despite increasingly fierce resistance, ultimately being halted by heavy enemy fire from Bloody Ridge and Government House Hill. Meanwhile, the 306th Regiment maintained its defensive position while probing the enemy’s fortifications around Iegusugu. The next day, the 306th began to pivot its right flank and launched an attack toward the Pinnacle with two battalions, making notable progress throughout the day. Concurrently, the 307th continued its advance into Ie despite facing heavy resistance, quickly reaching a standstill in front of Government House Hill.

As a result, with the 2nd Battalion effectively immobilized, the decision was made to deploy the 3rd Battalion around to the right flank to launch an assault toward the northeast in the eastern part of the town, while the 3rd Battalion of the 305th Regiment advanced eastward toward Iegusugu. After a heavy preparation by the artillery on Minna Shima, the 3d Battalion, 305th, attacked at 1130 on an 800-yard front. A house-to-house fight ensued amid the rubble of Ie. "Every street became a phase line," one observer reported. The necessity of forming a connecting link over the wide area between the 306th and the 307th made the fight harder. Artillery was ineffective against many enemy positions and could not be used freely because other friendly units were so close by. Self-propelled guns were held up by mines and debris in the narrow streets. After working about halfway through the northwestern section of the town, the troops withdrew to a more secure position on the outskirts, their right (south) flank then being 500 yards west of Government House Hill, and their left (north) flank 100 yards west of the base of Iegusugu. They had made a net gain of only about 350 yards for the day.

Similarly, Hamilton's 3rd Battalion achieved moderate success, advancing to a position 300 yards north of the village of Agarii-mae. To protect its right flank, the 1st Battalion of the 305th Regiment positioned itself alongside the 3rd Battalion of the 307th Regiment and launched a northern attack, gaining approximately 1000 yards by day's end before withdrawing to a position about 600 yards east of Agarii-mae. Medium tanks and self-propelled guns covered the gap that developed between the two battalions of the 307th. These weapons put direct fire into caves, pillboxes, and enemy gun positions in the town of Ie and the Pinnacle. They could not be moved close to the enemy positions, however; deadly machine-gun and mortar fire held the infantry back and left the armor vulnerable to suicide attacks by Japanese armed with satchel charges, who hid in holes until the tanks and guns came within range.

Meanwhile, after four days of intense fighting, activities in the Motobu area on April 18 were limited to reorganization, consolidating the gains from the previous day, patrolling the Itomi-Toguchi Road, and resupplying. Looking south, Griner called for a nighttime preliminary attack to secure the Machinato Inlet and the Urasoe-Mura Escarpment. As the area was shrouded in smoke during the afternoon, Company G of the 106th Regiment swiftly crossed the inlet and successfully secured Machinato by nightfall, while bridges were constructed at the inlet. The 106th then moved across the bridges, stealthily advancing toward the Urasoe-Mura Escarpment without encountering opposition. Near the summit, the troops launched a surprise ambush against the defenders, ultimately forcing the Japanese to retreat in chaos. With the escarpment secured by dawn, the 106th was prepared to participate in the general attack to the south.

The first Okinawa counteroffensive, as part of Operation Ten-Ichi-Go was not achieving results. Despite overwhelming sacrifices of men and supplies, it seemed hopeless for the Japanese on Okinawa. Those like Colonel Yahara could see the paint on the wall, much to their growing depression.

- 177 - Pacific War Podcast - Yamato's Last Stand - April 8 - 15 - , 1945

Last time we spoke about the invasion of Iwo Jima. In March 1945, as the Pacific War raged, the US Marines began and invasion of Iwo Jima while Allied forces advanced across the Philippines. The Japanese formed the 32nd Army to defend the island, but faced shortages of supplies and equipment. They mobilized Okinawan civilians for support and constructed extensive fortifications. The Americans launched Operation Iceberg, neutralizing enemy air facilities in the Ryukyus, Kyushu, and Formosa. Task Force 58 and other air forces struck Japanese targets, while Spruance's 5th Fleet prepared to land Buckner's 10th Army. Initial landings occurred in the Kerama Islands, followed by the main assault on April 1 on Okinawa's Hagushi beaches. Despite heavy bombardment, Japanese defenses remained concealed. The Americans encountered minimal resistance initially, but the stage was set for a bloody and brutal battle.

As we last left off, Admirals Turner and Spruance successfully landed over 60,000 troops from General Buckner’s 10th Army on the Hagushi beaches of Okinawa with minimal resistance. In response, General Ushijima’s main forces remained inactive in their underground positions in the south, having effectively endured the continuous naval and air assaults from the enemy. However, under pressure from higher authorities in Tokyo and Formosa, the 32nd Army began to develop plans for a general counteroffensive aimed at the Yontan and Kadena airfields, utilizing nighttime infiltration and close combat tactics. The primary response, however, was expected to come from the air. As part of Operation Ten-Go, all Army and Navy air forces stationed in the Home Islands were to focus their efforts in the East China Sea to execute a series of coordinated mass air strikes against enemy transport and carrier task forces, collectively referred to as the Kikisui attacks. Japan’s wartime terminology exploited the distinctively poetic and euphemistic nature of the Japanese language. The informal term kamikaze actually means “divine wind.” Specifically, kamikaze refers to the typhoons that miraculously wrecked Kublai Khan’s Mongol–Koryo invasion fleets in 1274. Like “blitzkrieg”, the unofficial term “kamikaze” was mostly used by Allied journalists. The IJN and IJA officially called suicide attack units tokubetsu kogekitai, meaning “special attack unit.” This was usually shortened to tokkutai, with tokko both noun and adjective meaning “special” i.e. suicide. Kikisui was the codename for the ten mass kamikaze attacks off Okinawa against the Allied fleet. Kikisui means “floating chrysanthemum,” which was the war emblem of legendary 14th-century samurai Masashige Kusinoke, a national exemplar of sacrificial devotion to the Emperor.

Ten-Go had been initiated on March 26, following the initial landings on the Kerama Islands; however, by the time of the invasion, Admiral Toyoda’s disorganized Combined Fleet was unable to carry out any large-scale kamikaze attacks, as it was still consolidating approximately 3,000 aircraft in Kyushu. Additionally, encouraged by Emperor Hirohito, Toyoda momentarily sanctioned a dramatic, one-way suicide mission involving the superbattleship Yamato and Rear-Admiral Komura Keizo’s 2nd Destroyer Squadron, aimed at destroying Spruance’s invasion fleet. This surface attack mission, codenamed Ten-Ichi-Go and led by Vice-Admiral Ito Seiichi of the 2nd Fleet, vaguely suggested that if Yamato reached Okinawa, she would ground herself as an artillery platform while her crew disembarked as naval infantry. Nonetheless, the chances of success for this mission were slim; it was primarily intended for the Imperial Japanese Navy to maintain its honor.

On April 2, while General Watson’s 2nd Marine Division conducted another demonstration off the southeast beaches, American forces prepared to advance eastward. In the south, benefiting from ideal weather and minimal resistance, the 17th Regiment secured the highlands overlooking Nakagusuku Bay and extended its patrols to the bay's shoreline. The 32nd Regiment eliminated a strongpoint south of Koza using tanks and then aligned with the 17th. The 381st Regiment advanced through Shimabuku but faced enemy resistance in and around Momobaru. Meanwhile, the 383rd Regiment captured a hill just south of Momobaru after a fierce battle and also took a ridge northeast of Futema with support from airstrikes, artillery, and tanks.

In the north, however, General Geiger’s Marines faced challenging terrain and supply issues. The 1st Battalion, 29th Marines moved north to secure the unoccupied Zampa Misaki area, where Turner later established a radar station. The 22nd Marines advanced quickly eastward throughout the day against light opposition, successfully securing the Nagahama beaches alongside the 6th Reconnaissance Company. On the other hand, the 4th Marines met with steadily mounting resistance. At 1100 a platoon of 3/4, entering the mouth of a steep ravine was met by a sharp fusillade of small-arms fire, which revealed a series of mutually supporting caves on both sides of the draw. In the fire fight that ensued, 12 wounded men were isolated and not recovered for four hours. "Every means of painlessly destroying the strongpoint was unsuccessfully tried and it was finally taken by a typical 'Banzai' charge, with one platoon entering the mouth of the draw and one platoon coming down one side of the two noses that formed the pocket." 

The 1st Marine Division continued its advance with little resistance to the Ishimmi-Kutoku line, also extending southward to Chatan, while the 1st Marines moved past the 5th Marines toward Chibana. With approximately 6,000 yards separating General Del Valle’s main frontline units from the 7th Division, General Arnold decided to send Colonel Roy Greene’s 184th Regiment to fill this significant gap. At sea, Admiral Mitscher’s Task Force 58 launched a strike against Amami Oshima, sinking three vessels and damaging two others, while also witnessing four warships collide and sustain damage. In retaliation, Admiral Ugaki’s Kyushu aircraft force conducted sporadic kamikaze attacks, resulting in damage to five transports.

The next day, General Hodge’s 24th Corps shifted its focus southward. The 17th Regiment secured the rear areas and captured Awase, while the 32nd Regiment advanced approximately 5,000 yards along Nakagusuku Bay to occupy Kuba and establish its lines in front of Hill 165. The 381st Regiment took control of Kishaba and Atanniya but failed in its assaults on Hill 165 and Unjo. Meanwhile, the 383rd Regiment swiftly occupied Isa, Chiyunna, and the Futema high ground. Looking north, Del Valle dispatched the 1st Reconnaissance Company to scout the area along the corps boundary, sweep the Katchin Peninsula, and patrol back up the east coast to the village of Hizaonna. This maneuver enabled the 1st Marines to advance quickly in formation and reach the sea wall overlooking the northern end of Nakagusuku Bay by nightfall. Concurrently, the 5th Marines moved forward and successfully occupied Agina and Tengan; the 7th Marines gained around 2,700 yards of enemy territory and ultimately reached Hizaonna, although Company K became lost and was ambushed. The 4th Marines navigated the challenging terrain and light enemy resistance to secure the significant hill mass behind Yontan airfield, located 3,000 yards short of the east coast. The 22nd Marines advanced and successfully captured Nakadomari, along with a position 400 yards south of that line. Meanwhile, the 6th Reconnaissance Company, supported by armored units, crossed the Ishikawa Isthmus to the village of Ishikawa, where they faced mortar fire. At sea, Mitscher’s aircraft carriers targeted Okinawa, sinking two vessels and damaging two others. In response, Ugaki was finally able to launch a preliminary mass Ten-Go air attack, with 119 aircraft causing damage to the escort carrier Wake Island, the destroyers Bennett, Prichett, and Foreman, the minesweeper Hambelton, and two landing craft.

Due to significant advancements, Geiger successfully deployed Colonel Victor Bleasdale’s 29th Marines to take control of the Yontan airfield and other rear areas. To the south, Del Valle’s units moved toward the eastern shore of Okinawa, with the 1st Marines occupying the Katchin Peninsula without facing any resistance, while the 5th and 7th Marine Regiments secured the coastline in their designated zones. Further south, after splitting the island in two, Hodge began advancing toward Naha, targeting the hill mass stretching from Urasoe-Mura to Hill 178 and Ouki. In response, General Bradley positioned Colonel Macey Dill’s 382nd Regiment in front of Nodake, while the 184th Regiment moved through the 381st in the Attaniya-Unjo area. For the initial push toward the Uchitomari-Tsuwa line, the 383rd Regiment advanced quickly from Isa to Mashiki, where they were ultimately halted by heavy fire from the south. The 382nd advanced over two miles south from Nodake along the eastern boundary of the division, while Arnold’s forward units lagged about two miles behind due to moderate resistance at a high, wooded ridge parallel to the coastline just west of Kuba. Meanwhile, at sea, Ugaki launched only sporadic kamikaze attacks, which resulted in damage to the destroyer Wilson near the Kerama Islands. Additionally, two American vessels collided while Task Force 58 targeted Okinawa, and later that night, a suicide boat attacked and sank an LCI gunboat.

In the Attaniya-Unjo area, the 383rd Regiment made a swift advance from Isa to Mashiki as part of the initial push towards the Uchitomari-Tsuwa line. However, the following day marked the onset of fierce resistance on Okinawa, with the 383rd Regiment struggling to make headway against the formidable Japanese defenses on Cactus Ridge. Meanwhile, the 382nd Regiment continued its advance southward against a series of fortified positions, achieving gains of approximately 400 yards to the east and 900 yards to the west. The 184th Regiment moved through Arakachi but was halted by intense and precise fire from a rocky outcrop located about 1,000 yards southwest. The 32nd Regiment finally managed to capture Castle Hill before pushing more than two miles along the coast to a point east of Ukuma. To the north, while the 1st Marine Division shifted to a primarily defensive posture, the 6th Marine Division conducted active reconnaissance toward the Motobu Peninsula, advancing the front to the Atsutabaru-Chima line. Additionally, a patrol from the 1st Marines on the Katchin Peninsula crossed the reef to seize Yabuchi Island swiftly. At sea, there were no kamikaze attacks that day as Ugaki and Toyoda prepared to launch the main phase of Operation Ten-Go, although an Okinawa shore battery managed to hit the battleship Nevada. Unbeknownst to the Japanese, American intelligence had successfully intercepted Combined Fleet codes, allowing them to anticipate the details of the surface Ten-Ichi-Go attack. Consequently, Spruance’s warships were prepared for the imminent departure of Ito’s “Surface Special Attack Force,” which was executed a few hours later. Additionally, Ushijima was instructed to initiate a strong counterattack the following day to coincide with Ten-Ichi-Go and the first Kikisui attack, but he firmly rejected this order and called for the cancellation of the unnecessarily suicidal surface attack.

During the night, as Admiral Blandy’s minesweepers completed the perilous task of clearing the vast areas of Chimu and Nakagusuku Bays, the Fleet Marine Force Amphibious Reconnaissance Battalion landed on the northern coast of Tsugen Island to gather intelligence on enemy positions. Upon their arrival in the early hours of April 6, they encountered machine-gun and mortar fire, which ultimately compelled the battalion to retreat to the beach and reembark. Simultaneously, the 4th and 29th Marine Regiments advanced through the 22nd Marine Regiment, with the 29th Marines moving up the west coast in formation and reaching Chuda by noon, while the 4th Marines progressed along the eastern coastal road, successfully advancing seven miles toward Madaira. Further south, the 383rd Regiment continued its assault on the fortified enemy positions at Cactus Ridge, pushing forward relentlessly until they secured the western half by nightfall. The 2d Battalion, 383d Infantry, made frontal assaults through intense mortar fire to gain the ridge. "We figured," S/Sgt. Francis M. Rall later wrote, "that the way to get out of that knee mortar fire was to get to where it was coming from. So we stood up in waves, firing everything we had and throwing hand grenades by the dozen, and charged the Jap position." By such tactics the 2d Battalion gained the western half of Cactus. 

Over the next two days, the 382nd Regiment advanced slowly east of the Ginowan road, facing fierce resistance from the Tombstone and Nishibaru Ridges. After a 10-minute artillery bombardment, two companies of the 1st Battalion, 184th Regiment climbed nearly to the summit of the Pinnacle but were ultimately pushed back by strong resistance from caves and underground strongholds. Undeterred, Company B continued frontal assaults while Company C maneuvered up the western approaches to surprise the determined defenders. This strategy proved effective, with Company C reaching the top without sustaining any casualties and then methodically eliminating the remaining Japanese troops using white phosphorus grenades and flamethrowers. As the Pinnacle was being captured, the 32nd Regiment advanced across the coastal flatlands with minimal resistance to maintain contact with the 184th Regiment.

On this day, Task Force 58 returned to sea, launching strikes on Okinawa and the Daito Islands, while Admiral Rawlings' Task Force 57 targeted the Ishigaki and Miyako Islands. Meanwhile, Japanese aerial reconnaissance identified two American carrier groups near Okinawa, prompting Ugaki to initiate his first mass Kikisui attack, sending hundreds of Japanese aircraft to assault Mitscher's carriers. US carriers unleashed a combined 19 USN and four USMC squadrons to blunt the onslaught. Swirling, running dogfights developed around noon and lasted through sunset. April 6 may have started slow, but by evening it had developed into one of the greatest aerial confrontations of all time. American CAPs overwhelmingly massacred the poorly trained Japanese attackers; Mitscher’s Task Force 58 fighters claimed 249 Japanese planes for just two lost—a staggering 125-to-1 kill ratio. Yet the kamikaze pilots’ grim determination was chillingly apparent. According to VF-82’s action report: “Of all the enemy planes encountered, not one returned fire, all remained on course, boring in toward the surface vessels. The only evasive action offered was jinking, and the majority of the aircraft were obsolete models as can be seen by the list [of] destroyed. Primary danger to our pilots was collision or getting in the path of a friendly plane’s fire.” Essex’s VF-83 (36 Hellcats) and VBF-83 (36 Corsairs) combined for 69 kills, while Belleau Wood’s 24 VF-30 Hellcats shot down 47. Belleau Wood’s skipper, Captain Red Tomlinson, duly signaled Task Group 58.1’s Rear Admiral Joseph J. Jocko Clark: “Does this exceed the bag limit?” Clark responded, “Negative. There is no limit. This is open season. Well done.” The US carrier fighters’ 275 kills was thus the war’s 4th-highest 1-day total. 13 US pilots achieved ace status (scored their 5th kill) on April 6, with 4 becoming “ace-in-a-day.” 10 pilots claimed 4 kills, while another 17 shot down 3 each. Combined with anti-aircraft fire, the Americans destroyed 355 Japanese planes.

However, even significant aerial victories could not prevent the devastating kamikaze assaults, with approximately 182 Japanese aircraft in 22 groups attacking Spruance's 5th Fleet that afternoon. This led to 24 kamikaze planes sinking the destroyers Bush and Colhoun, as well as three transport ships, and inflicting further damage on the light carrier San Jacinto, 12 destroyers, three destroyer minesweepers, and one minesweeper. Friendly anti-aircraft fire also caused damage to battleship North Carolina, light cruiser Pasadena, and destroyer Hutchins. Despite the extensive damage, four new escort carriers arrived off Okinawa that day, bringing the first 222 fighters of Major-General Francis Mulcahy's Tactical Air Force, stationed at Yontan airfield. Meanwhile, the Yamato force set sail at 15:24 towards Okinawa, but within 45 minutes, a B-29 spotted them in transit. Submarine Threadfin then detected Ito's strike force moving through the Bungo Strait at 17:45. As Ito's force rounded Kyushu to the southwest, it was monitored overnight by submarine Hackleback, which sent four additional contact reports and was pursued three times briefly by one of Yamato's escorting destroyers.

Concerned about a potential mass Kikisui attack on April 7, Spruance ordered Mitscher’s carriers to concentrate on thwarting Japanese air assaults while tasking Admiral Deyo’s Task Force 54 with intercepting Ito’s strike force. At 06:20, April 7, six Zeros of the 203rd Kokutai arrived over Yamato as CAP. 14 total Zeros would relay in small groups over the Yamato task force, but all would depart as scheduled by 10:00. The Americans already knew the exact CAP schedule of Yamato’s fighters, a later US intelligence memo dryly observing, “They left too soon.” At 08:32, an Essex Hellcat reported the Yamato task force southwest of Koshiki Retto at a heading of 300 degrees. The Yamato group was doing 22kts and deployed in a diamond formation, with Yamato in the center and Yahagi astern. Yamato simultaneously reported that she had been sighted. Visibility was highly variable, with patchy overcast. Within minutes, two VPB-21 PBM-3 Mariner flying boats (based at Kerama Retto with seaplane tender Chandeleur) arrived and began shadowing Yamato and radioing situation reports. Meanwhile, Mitscher duly reported the Yamato sighting to Spruance, before dispatching 16 additional fighters at 09:15 to track Yamato. Shortly after Yamato’s CAP had departed, at 10:14, the Japanese discovered the two shadowing PBM-3 Mariners, and simultaneously reported a US submarine stalking the task force—this was Hackleback, which had managed to catch back up with the zig-zagging Japanese. Three minutes later, at 10:17, Yamato turned towards the Mariners and opened fire with her awesome 18.1in. Sanshikidan anti-aircraft shells. Yahagi also opened fire, and additionally began jamming the Mariners’ transmissions. The Mariners retreated into the clouds unharmed at 10:18, and Yamato and Yahagi ceased fire. To his chief-of-staff, Commodore Arleigh Burke, Mitscher announced: “Inform Admiral Spruance that I propose to strike the Yamato sortie group at 1200hrs unless otherwise directed.” The grizzled aviator desperately wished to sink Yamato, but he likely suspected that Spruance, riding New Mexico, intended his beloved dreadnoughts claim one last moment of glory. “Will you take them or shall I?” Mitscher pressed. Spruance’s response: “You take them.”

At 10:00, the carriers of Task Groups 58.1 and 58.3 launched the first wave of 282 aircraft, although only 227 managed to locate Ito’s strike force as they navigated through challenging, overcast weather. At 11:07, Yamato’s radars detected the large formation approaching from 63 nautical miles away, prompting Ito to increase speed to 25 knots. Within eight minutes, the formation closed to 44 nautical miles, leading the Japanese to initiate sharp evasive maneuvers. Bennington’s Lieutenant-Commander Hugh Woods’ airborne radar detected the Yamato task force some 25nm away from its predicted location, and the US strike altered course. Five minutes later, the Americans made visual contact through a hole in the patchy 3,000ft overcast, a Hornet pilot recalling, “Yamato looked like the Empire State Building plowing through the water.” Yamato cruised in the center, flanked by destroyers Kasumi, Suzutsuki, Hamakaze, and Yukikaze. Light cruiser Yahagi was in the van, followed by destroyers Hatsushimo, Isokaze, and Fuyutsuki.

The first American aviators encountered the destroyer Asashimo, which had been experiencing machinery issues for five hours and had fallen 12 nautical miles behind the main task force to the north. San Jacinto’s seven Hellcats dove against Asashimo, but the crippled destroyer threw up notably heavy flak. The Hellcats’ 1,000lb bombs closely straddled Asashimo, buckling the destroyer’s hull plating. The Hellcats then repeatedly strafed the destroyer, causing large fires that quickly silenced Asashimo’s guns. San Jacinto’s eight Avengers then made a textbook attack run at 300ft, dropping torpedoes from 1,200 to 1,600yds range. Trailing a wide oil slick, the crippled Asashimo attempted to comb the torpedoes, but one struck beneath her bridge and a second hit near her engine room. Successive explosions blew Asashimo partly out of the water and broke her in half. Asashimo sank at 1213hrs, going down with all 330 men. She had lasted three minutes against San Jacinto’s attack. Twelve miles ahead, Yamato lookouts spotted the incoming aircraft at 12:32, which then spent the next five minutes circling just outside the range of Japanese anti-aircraft fire to coordinate their strike plan. Around this time, Yamato also raised Togo’s iconic Tsushima flag signal: “On this one battle rests the fate of our nation. Let every man do his utmost.”At 12:37, the circling planes launched their coordinated assault on Yamato and her escorts, focusing on the superbattleship’s port side in an attempt to capsize her. US fighters repeatedly strafed Yamato with their 5in. rockets and 0.50cal. machine guns, decimating Japanese antiaircraft batteries and slaughtering exposed antiaircraft crews. The intense carnage and chaos that followed suppressed careful targeting and further ravaged Japanese gunners’ morale.

Yamato was maneuvering hard at her flank speed of 27kts, when at 1240hrs four Bennington Helldivers from VB-82 delivered two 1,000lb bombs near Yamato’s mainmast. The first bomb exploded in Yamato’s crew quarters. The second detonated near Yamato’s aft command station and caused serious damage, destroying one of Yamato’s two air search radars, her after secondary gun director, and several 25mm antiaircraft guns. The subsequent fires shortly reached the powder handling area beneath Yamato’s after 6.1in. turret and detonated the readyuse propellant. The resulting conflagration virtually exterminated the 6.1in. turret crew, but flash doors prevented the explosion from reaching the rest of the magazine. Nevertheless, the explosion killed the area’s entire damage control party, meaning the resulting fire would rage uncontrolled for the rest of the battle. The Americans lost one Helldiver. At 1243hrs, eight Hornet Avengers launched torpedo attacks against Yamato’s port side, covered by 14 Bunker Hill Corsairs strafing Yamato with rockets. Antiaircraft fire hit six Avengers, destroying one, but at least three torpedoes hit the water. The first two torpedoes missed, but at 1245hrs the third torpedo slammed into Yamato’s port side, opening her hull to 2,235 tons of seawater. Japanese damage control counterflooded with 604 tons of water to correct the list. Attempting to draw US attackers from Yamato, Hara’s light cruiser Yahagi had maneuvered away from the Japanese battleship, steaming hard at 35kts. US strafing had already ricocheted machine gun bullets around Yahagi’s bridge, killing a lookout. Watching the attack unfold, Hara admitted, “The spectacle was at once thrilling and terrifying.” Meanwhile, Bennington’s Lieutenant-Commander Ed De Garmo led three Avengers against Yahagi. At 1246hrs, De Garmo’s Avengers delivered Yahagi her first hit and it was a devastating one. A single torpedo struck Yahagi in the engine room, killing the entire engineering crew. Yahagi was left dead in the water nine minutes into the battle. Destroyer Isokaze subsequently sped towards Yahagi to take off Rear Admiral Komura.

Meanwhile, around 56 aircraft targeted Yamato’s escorting destroyers, leading to multiple torpedo hits that split Hamakaze in two; Isokaze was bombarded with bombs; Fuyutsuki suffered minor damage from two dud rockets; and Suzutsuki was struck by a bomb that severed her bow. The first wave of attacks concluded at 12:50, as Ito sought to reorganize his forces and evaluate Yahagi’s status. Shortly after 13:00, a second wave of 50 aircraft appeared, managing to hit Yamato’s port bow with a bomb at 13:23 and inflicting several bomb hits near the battleship’s bridge. Additionally, two bomb hits and several near misses critically damaged the destroyer Kasumi, leaving her dead in the water and ablaze. At 1333 the third wave of US attackers arrived, comprising 110 new Yorktown, Intrepid, and Langley aircraft from the delayed TG-58.4 strike. The Americans now overwhelmingly focused on the reeling Yamato. Twenty Avengers attacked Yamato’s portside. Around 1337, the third wave saw three confirmed torpedo hits on Yamato’s portside, plus a fourth probable hit, increasing her portside list to 15–16 degrees. Stationed on Yamato’s bridge, Ensign Mitsuru Yoshida recalled, “I could hear the Captain vainly shouting, ‘Hold on men! Hold on men!’”. Aruga had no option but to flood Yamato’s starboard machinery spaces, where hundreds of engineers toiled to keep Yamato underway. Water, both from torpedo hits and the flood valves rushed into these compartments and snuffed out the lives of the men at their posts, several hundred in all. Caught between cold sea water and steam and boiling water from the damaged boilers, they simply melted away.” Aruga’s drastic measure reduced Yamato’s portside list back to five degrees, but exhausted her last starboard counterflooding capacity. Having lost one shaft and gained 3,000 tons more water, Yamato’s speed fell to 12kts. At 1342hrs, TG-58.4 Avengers dropped another four torpedoes. Yoshida marveled, “That these pilots repeated their attacks with such accuracy and coolness, was a sheer display of the unfathomable, undreamed-of strength of our foes!” Yamato shot down one Avenger, but two torpedoes plowed into Yamato’s portside, making five torpedo hits in five minutes. The Americans had intentionally targeted Yamato’s stern to wreck her steering, and the gamble paid off. Yamato’s rudders were now disabled, jamming her in a permanent starboard turn. Any chance of reaching Okinawa was gone.

Reduced to a speed of 8 knots and unable to maneuver, the stricken Yamato became an easy target. Around 14:02, Mitscher’s relentless carrier planes inflicted at least four more bomb hits, disabling most of Yamato’s remaining operational anti-aircraft guns as the battleship helplessly circled. As a result, Ito canceled the Ten-Ichi-Go attack and promptly ordered all his warships to rescue survivors and attempt to retreat to Japan. The sinking battleship was then deserted, except for Ito and Captain Aruga Kosaku, who chose to go down with their ship. 

Throughout the battle, a stoic Ito had sat silently with arms crossed on Yamato’s bridge, unflinching as bullets ricocheted around him, slaughtering his staff. Ensing Yoshida Mitsuru now observed that Ito “struggled to his feet. His chief of staff then arose and saluted. A prolonged silence followed during which they regarded each other solemnly.” Ito then told his staff, “Save yourselves. I shall stay with the ship.” Ito then shook hands deliberately with his officers, retired to his sea cabin one deck below, and locked it behind him. Meanwhile, with Yamato’s pumps no longer functioning, alarms began to blare: temperatures in the 18.1-inch magazines were approaching dangerous levels. By 14:20, the capsizing Yamato’s main deck was vertical to the ocean. Captain Aruga, eating a biscuit given to him by a rating, tied himself to a binnacle on Yamato’s bridge. As Yamato capsized, surviving men clambered across her keel, a crazed, half-naked officer screaming and brandishing his samurai sword at the Americans. 

Meanwhile, the Americans continued pummeling the helpless Yahagi, which “quivered and rocked as if made of paper,” recalled Captain Hara. The stricken Yahagi suffered repeated hits. “My proud cruiser,” Hara brooded, “was but a mass of junk, barely afloat.” Around 1400hrs Yahagi took the decisive torpedo hit, triggering a clearly fatal starboard roll. Hara finally ordered, “Abandon ship.” At 1405hrs, one minute after receiving her last bomb, Yahagi capsized and sank, having somehow absorbed at least 12 bombs and seven torpedoes. Captain Hara and Rear Admiral Komura calmly stepped into the water as Yahagi sank from beneath them, only barely surviving the sinking Yahagi’s undertow. Now clinging to floating wreckage, the exhausted Hara observed “scores of planes swarming about [Yamato] like gnats.”

By 14:20, the capsizing Yamato's main deck was vertical to the ocean, and three minutes later, the sinking dreadnought exploded catastrophically before finally disappearing beneath the East China Sea. Yamato’s capsizing motion had likely forced open her 18.1in. powder room doors, allowing fires into the battleship’s magazines. An American gunner described the explosion as “the prettiest sight I’ve ever seen … A red column of fire shot up through the clouds and when it faded Yamato was gone.” The detonation killed most Yamato survivors still struggling in the water and may have destroyed several US aircraft. The Americans’ exact score will never be known, but Yamato had certainly absorbed seven bombs and nine to twelve torpedoes out of 150 torpedoes dropped. The US planes departed at 1443, but not before issuing “a few farewell strafing runs across the Yamato survivors.” Destroyers Suzutsuki, Fuyuzuki, Yukikaze, and Hatsushimo rescued 1,620 men, including Hara and Komura, before successfully returning to Japan. Additionally, the disabled destroyers Isokaze and Kasumi were scuttled by Yukikaze and Fuyuzuki, respectively. By the end of the action, the combined losses for Ten-Ichi-Go totaled 4,242 Japanese lives. Meanwhile, Ugaki had launched a second mass kamikaze attack around noon, sending 132 aircraft towards Task Force 58. Although Mitscher’s fighters shot down 54 attackers, the kamikazes managed to damage the fast carrier Hancock, the battleship Maryland, the destroyers Bennett and Wesson, and a motor minesweeper.

The initial Kikisui operation resulted in the deaths of 485 Americans and left 582 wounded. The significant losses over the two days hindered Ugaki from launching another large-scale Kikisui attack for five days. Meanwhile, back in Okinawa on April 7 and 8, Hodge continued his offensive in the south. In Bradley’s sector, the 383rd Regiment persistently executed banzai charges against the remaining enemy strongholds on Cactus Ridge until the entire area was secured by American forces. They then advanced toward Kakazu Ridge, where they faced even stronger resistance. The 382nd Regiment made a slow but steady push forward, ultimately being halted by intense fire across a broad front just north of Kaniku and Tombstone Ridge. 

The fighting in the 7th Division's sector on April 7 centered on a low, bare hill 1000 yards west of the town of Minami-Uebaru, called Red Hill because of its color. The enemy had made a fortress of the hill by constructing his usual system of caves and connecting trenches. A frontal assault on Red Hill by troops of the 3rd Battalion failed in the face of machine-gun and mortar fire. In a 2nd attempt, 3 platoons of tanks supported the attack. 10 medium and 5 light tanks advanced through a cut toward Red Hill; 2 tanks were blown up by mines and 1 was satchel-charged as the column moved toward the hill and up the sides. Intense enemy artillery and machine-gun fire drove the infantry back and disabled more tanks. Japanese swarmed in among the armor and tried to destroy the tanks with satchel charges and flaming rags. 2 medium tanks held off the attackers, the defending crews resorting to hand grenades, while the rest of the operative tanks withdrew. The 14th Independent Battalion headquarters proudly described this action as a perfect example of how to separate troops from tanks and thus break up the American infantry-tank team. The enemy dispatch stated: "The above method of isolating the troops from the tanks with surprise fire followed by close combat tactics is an example in the complete destruction of enemy tanks and will be a great factor in deciding the victories of tank warfare." After these 2 reversals the 3rd Battalion made a wide enveloping maneuver to the right. Behind fire from artillery and supporting weapons, the troops drove toward Red Hill from the west and occupied it, suffering only 2 casualties in the move. Once more a Japanese outpost had shown its strength against a frontal attack and its vulnerability to a flanking maneuver. The capture of Red Hill left another sector of enemy territory open for the taking. The troops advanced 100 yards south before digging in. A platoon of tanks conducted a remarkable 4000-yard foray almost to Hill 178 and withdrew safely, despite a bombing attack by two single-engined Japanese planes.

The following day, the 184th continued its advance southward under heavy fire, managing to take Triangulation Hill after two fierce assaults. Simultaneously, the 32nd Regiment captured Tsuwa as it extended the front along the coastline. By the night of April 8, the 24th Corps had sustained 1,510 battle casualties while inflicting 4,489 Japanese fatalities and capturing 13; they had finally reached the formidable perimeter of the Shuri fortified zone. Looking north, on April 7, the Fleet Marine Force Amphibious Reconnaissance Battalion landed on Ike Island, encountering no opposition. Subsequently, Company B was dispatched to secure Takabanare Island, while Company A took control of Heanza and Hamahika Islands. During the night, Company B reembarked, maneuvered around Tsugen Island, and landed on Kutaka Island, where they also found no enemy presence.

Simultaneously, the 32nd Regiment captured Tsuwa as it expanded the front along the coastline. By the evening of April 8, the 24th Corps had incurred 1,510 battle casualties. On the same day, Shepherd advanced north with minimal resistance, as the 29th Marines successfully reached Nago while the 4th Marines moved through Henoko. Ahead of the division, the 6th Reconnaissance Company traveled up the west coast road to the village of Awa and then crossed the base of the Motobu Peninsula to Nakaoshi, encountering and either destroying or scattering several enemy groups along the way. As the reconnaissance zone was extended westward on April 8, clear signs, confirmed by aerial observations and photographs, indicated that the enemy had chosen the rugged mountains of Motobu as their defensive position. As a result, the 22nd Marines were deployed across the island from Nakaoshi to Ora to protect the right flank and rear of the 29th Marines attacking westward, while the 4th Marines assembled near Ora to support either the 29th on Motobu or the 22nd in the north. The 2nd Battalion, 29th Marines probed westward, moving across the base of Motobu and occupying the village of Gagusuku. Additionally, the reserve 1st Battalion at Yofuke successfully secured Yamadadobaru and Narashido, facing heavy enemy machine-gun and rifle fire at the latter location. The following day, the 29th Marines advanced in three columns to locate the enemy's main force at Motobu; all columns encountered resistance, revealing that a significant enemy force confronted the division in the area stretching from Itomi to Toguchi. On April 10, the 2nd Battalion, 29th Marines captured Unten Ko, where the Japanese had established a submarine and torpedo boat base; the 3rd Battalion took Toguchi and sent patrols into the interior, while the 1st Battalion advanced through Itomi and uncovered well-fortified positions on the high ground north of the village.

On April 9, the 184th Regiment successfully captured Tomb Hill in the south following an artillery and air bombardment, while the 32nd Regiment took control of several finger ridges to the east that oversaw the approaches to Ouki. The Japanese-held area in front of the 383rd Regiment offered the enemy an ideal combination of defensive features. A deep moat, a hill studded with natural and man-made positions, a cluster of thick-walled buildings behind the hill; these were the basic elements of Kakazu stronghold. The enemy had exploited each one of them. Moreover, Kakazu, unlike such outposts as the Pinnacle, was an integral element of the Shuri fortified zone and a vital rampart that could expect reinforcements and heavy fire support from within the ring of positions that surrounded the 32nd Army headquarters, only 4000 yards to the south. Between the Americans and Kakazu lay a deep gorge, half hidden by trees and brush, which could be crossed only with difficulty. The Kakazu hill mass itself, which was made up of two hills connected by a saddle, stretched northwest-southeast for 2000 yards, sloping on the west toward the coastal flat and ending on the east at Highway 5. Just below Kakazu Ridge on the southeast was the town of Kakazu, a compact group of tile-roofed structures, each surrounded by hedges and stone walls and somewhat in defilade to the adjoining open fields. In and around the Kakazu hills the Japanese had created one of their strongest positions on Okinawa. Mortars dug in on the reverse slope were zeroed-in on the gorge and on vulnerable areas between the gorge and the crest of Kakazu. Several spigot mortars also protected the hill. In an intricate system of coordinated pillboxes, tunnels, and caves Japanese machine-guns were sited to cover all avenues of approach. The enemy was also supported by many artillery pieces within the Shuri fortified zone. The heavy walls and the hedges of the town of Kakazu-and eventually its rubble-afforded the Japanese countless defensive positions.

Concurrently, the 383rd Regiment initiated its first coordinated assault on Kakazu Ridge, with Companies A, C, and L swiftly reaching the summit by dawn without detection. However, the surprised defenders quickly launched a fierce counterattack, ultimately forcing Companies A and C to withdraw. Company L, positioned on Kakazu West, continued to fend off enemy counterattacks alone until late afternoon when the exhausted unit had no choice but to retreat. The next day, Brigadier-General Claudius Easley proposed a "powerhouse attack," where the 381st Regiment would assault Kakazu West from positions south of Uchitomari while the 383rd would press on Kakazu Ridge from positions north of the gorge. Following a heavy artillery bombardment, the assault commenced, with the 2nd Battalion of the 381st Regiment rapidly fighting through strong enemy defenses to secure the crest of Kakazu West. However, the 383rd was struggling to make headway, prompting Colonel May to direct his two battalions to execute flanking maneuvers. Although the eastern encirclement was unsuccessful, May's 3rd Battalion managed to cross the gorge at the northern base of Kakazu West to join Colonel Halloran's 2nd Battalion on the crest. Both units then attempted to advance eastward in heavy rain, but relentless Japanese counterattacks forced them back to Kakazu West. Stalemated, Easley eventually ordered Halloran's 1st Battalion to move through May's 3rd Battalion to attack southeast along Kakazu Ridge, but this assault was also repelled by the determined defenders. At the same time, the 382nd Regiment launched its primary assault on Tombstone Ridge, advancing southwest with three battalions in formation but managing to gain only a few hundred yards to the west as fierce defenders thwarted their main offensives against the hills held by the Japanese. Meanwhile, to the east, the 32nd Regiment attempted to advance into the town of Ouki without success, while the 184th Regiment on the heights defended against minor counterattacks, sealed off caves, and solidified their positions.

The battle for Okinawa is really heating up, showcasing to the Americans they would be paying dearly for every foot they took off the island. Meanwhile the last stand of the super battleship Yamato would form a legend encompassing the defiant spirit of Japan as well as producing one of the most bizarre science fiction animes of all time.

- 176 - Pacific War Podcast - the Invasion of Okinawa - April 1 - 8 - , 1945

Last time we spoke about the Visayas Offensive. In March 1945, the Pacific War raged on. On Iwo Jima, the US Marines, after intense fighting and heavy casualties, declared the island secured. Meanwhile, in northern Luzon, General Clarkson's division advanced towards Baguio, facing fierce Japanese resistance, while General Mullins pushed through Balete Pass. The Japanese army, grappling with severe supply shortages, was forced to evacuate Baguio. In the Visayas, General Eichelberger's forces targeted the Sulu Archipelago and Central Visayan Islands, securing key airfields. The 40th Division landed on Panay, capturing Iloilo, and launched an assault on northern Negros. On Cebu, the Americal Division landed near Talisay, encountering mines but minimal resistance, and secured Cebu City. By April, Allied forces had made strategic advances across the Philippines, overcoming Japanese resistance and establishing crucial airfields.

We have come to the grand final battlefield at last, that of Okinawa. Of course battles are raging in all sorts of other theaters like New Guinea, China, Burma, etc. However as you might imagine its becoming impossible given the week by week format to cover all of this in single episodes. So we are going to hardcore focus on Okinawa for awhile, we will circle back to the other theaters to catch up. Seriously it was the only logical way to do this and honestly in retrospect I wish the entire podcast was campaign by campaign instead of week by week. But I am a mere podcaster following the youtube series of this. But if you want to hear a campaign by campaign series, over at Echoes of War me and my cohost Gaurav are beginning to roll them out. The first series will be the entire Malayan Campaign, and I think after that I might try to do the Philippines. Regardless lets jump into the invasion of Okinawa.

As previously noted, the directive issued by the Joint Chiefs of Staff on October 3 designated Okinawa as the final target for invasion, following the establishment of air and naval bases in Luzon and Iwo Jima. Capturing this crucial island would bring the conflict to Japan's doorstep, disrupt the enemy's air communications through the Ryukyu Islands, and flank their maritime routes to the south. Consequently, from these newly established air and naval bases in the Ryukyus, American forces would be able to launch attacks on Japan's main islands and implement a more rigorous sea and air blockade, isolating them from Japanese territories to the south. This made it imperative for the Japanese Empire to maintain control over Okinawa and the Ryukyus. To this end, the 32nd Army, led by Lieutenant-General Watanabe Masao, was formed there by late March 1944. Initially, it comprised four companies and one artillery regiment stationed at Amami Oshima; five companies and one artillery regiment at Nakagusuku Bay; four companies and one artillery regiment at Iriomote Island; along with various garrison units from the 19th Air District in Okinawa. 

Under Operation Tei-Go, the Ryukyus and Formosa were to form a long zone of interprotective air bases. These bases were expected to defeat any American sea or air forces sent into the region. To avoid destruction from the air, each base was to consist of a cluster of airfields, such that if one were damaged others could be used immediately. Military and civilian crews were promptly set to work building the numerous fields. 13 base clusters had to be created, stretching in a line from Tachiarai in the northern Ryukyus to Pingting on Formosa in the south. The only remaining tasks for ground forces were the defense of these facilities and their support anchorages and the unenviable work of building the fields. Much of the energy of 32nd Army would be absorbed building these air facilities. This was more difficult since 32nd Army had only two bulldozers and one earth roller. Japan had produced dozers in small numbers at its Komatsu plant since 1943, but few had reached the front. Since soldiers were thus obliged to use shovels, hoes, straw baskets, and horse-drawn wagons, construction was slow. Moreover, because of enemy submarine raiders, it was impossible for the Japanese to deliver the large quantities of fuel, ammunition, and anti-aircraft guns needed to operate the bases. Even more seriously, the planes themselves were not available.

Between April and June, the 32nd Army received reinforcements, including the 44th and 45th Independent Mixed Brigades, the 21st Independent Mixed Regiment, and the 27th Independent Anti-Aircraft Artillery Battalion, among other air garrison units. From these forces, Watanabe chose to send the 45th Brigade to establish bases on Miyako Island and Ishigaki Island, while the 21st Regiment was tasked with setting up a base on Tokunoshima. On June 27, the 1st and 2nd Infantry Corps (approx. 4100 men) boarded the Toyama Maru and began the voyage to Okinawa. The 44th Brigade HQ, Artillery and Engineer Units meanwhile boarded other vessels of the Taka-412 convoy. Two days later, while the convoy was sailing east of Tokunoshima, the submarine Sturgeon successfully sank the Toyama Maru with two torpedoes, therefore inflicting the loss of 3724 men and much heavy equipment. Because of this, the 1st Corps had to be deactivated. 

Following the fall of Saipan, the Japanese Empire rapidly deployed significant ground forces to the 32nd Army, including the 9th, 24th, 28th, and 62nd Divisions, as well as the 59th, 60th, and 64th Independent Mixed Brigades, and the 27th Tank Regiment. Additionally, the 15th Independent Mixed Regiment was airlifted to bolster the beleaguered 44th Brigade, which was reorganizing its 2nd Corps with local recruits. The 32nd Army Staff wished to use as much of the indigenous population as it could in direct support of the war effort, so on January 1 1945 it ordered total mobilization. All Okinawan males aged 18 to 45 were obliged to enter the Japanese service. 39000 were drafted, of whom 15000 were used as nonuniformed laborers and 24000 as rear-echelon troops called the Home Guard (Boeitai). Many of the Boeitai replaced sea based battalions and rear-area supply units that had been reorganized and equipped for frontline duty. In addition to these, 1500 of the senior boys of the middle schools on Okinawa were organized into Iron and Blood Volunteer Units and assigned to frontline duty. Some of these students had been tried out in the signal service in the autumn of 1944 with good results, so the program was expanded. Since the fall of 1944, 600 senior students of the girls' middle schools also had been given training in the medical service.

While most of these troops were sent to strengthen the main defenses at Okinawa, a large portion of the 28th Division was actually assigned to reinforce the garrisons on the Miyako and Yaeyama Islands. The 36th Regiment was dispatched to support the Daito Islands, the entire 45th Brigade was moved to garrison Ishigaki and the rest of the Yaeyamas, the 59th Brigade was tasked with defending Irabu Island, the 60th Brigade was sent to reinforce Miyako Island, and the 64th Brigade was deployed to the Amami Islands. On August 9, Lieutenant-General Ushijima Mitsuru took command of the 32nd Army. His initial strategy was to occupy all of Okinawa with a strong force and eliminate any invading troops at their landing sites. As fierce fighting began at Leyte, intensive training for the troops commenced, including divisional maneuvers at potential American landing points, artillery bombardments of beachheads, and nighttime assaults on bridges. However, on November 13, Tokyo decided to send the elite 9th Division to Formosa to prepare for a movement to the Philippines that ultimately did not occur. The unexpected withdrawal of the 32nd Army’s best division disrupted Ushijima’s operational plans. Ironically, this situation improved combat efficiency, as it compelled the army to achieve more with fewer resources.

Ushijima chose to concentrate most of his forces in the mountainous and easily defensible Shimajiri area, located in the southern part of the island. This strategic location allowed the Japanese to maintain control over Naha port and target the northern airfields with artillery. Similar to the situation in Iwo Jima, this decision marked a departure from the previously favored strategy of a "decisive battle," opting instead for a war of attrition that had proven effective at Peleliu and Iwo Jima. As a result, Ushijima positioned Lieutenant-General Amamiya Tatsumi’s reinforced 24th Division at the southern end of the island, Lieutenant-General Hongo Yoshio’s reinforced 62nd Division along the central isthmus, Major-General Suzuki Shigeji’s reinforced 44th Independent Mixed Brigade on the Hagushi plain, and Colonel Udo Takehiko’s Kunigami Detachment, consisting of two battalions from the 2nd Corps, in northern Okinawa. These troop placements were successfully implemented in December; however, concerns arose that the 32nd Army was spread too thin to effectively counter the anticipated enemy invasion. Consequently, on January 15, Ushijima decided to move the 44th Brigade from the Hagushi plain southward to overlap with the 62nd Division's area on the east, significantly shortening the Japanese front. Additionally, one battalion from the Kunigami Detachment was sent to defend Iejima and its crucial airbase, which necessitated the rest of the unit to consolidate its positions and strengthen defenses on Yaedake Mountain in the Motobu Peninsula. Ushijima also had the support of the brigade-sized 5th Artillery Group, led by Lieutenant-General Wada Kosuke; the 21st Field Anti-Aircraft Artillery Corps; the 11th Shipping Group, which included several shipping engineer regiments and sea-raiding battalions; the 19th Air District overseeing various aviation service units; and Rear-Admiral Ota Minoru’s Okinawa Naval Base Force, which comprised nearly 9,000 personnel stationed at the Oroku Naval Air Base near Naha.

Ushijima had nearly 100,000 troops at his command, with 29,000 assigned to specialized units for anti-aircraft, sea-raiding, and airfield operations. Anticipating the nature of the impending conflict, these well-staffed service units were reorganized for ground combat. The 19th Air District transformed into the 1st Specially Established Regiment, responsible for defending the Yontan and Kadena airfields it had recently constructed and maintained. Most of the service personnel were integrated into the new 1st Specially Established Brigade in the Naha-Yonabaru area, while the sea-raiding base battalions became independent infantry units. Additionally, the remainder of the 11th Shipping Group was restructured into the 2nd Specially Established Brigade on the southwestern part of Okinawa. This reorganization, completed on March 21, bolstered ground combat strength by 14,000 men, leaving only 10,500 of the 67,000 Army personnel in specialized roles. To protect themselves, the Japanese began constructing robust fortifications, tunnels, and cave systems to shield against anticipated enemy bombardments. 

Work on the caves was begun with great vigor. "Confidence in victory will be born from strong fortifications" was the soldiers' slogan. The caves meant personal shelter from the fierce bombardments that were sure to come, and they also offered a shimmering hope of victory. The combination was irresistible, and units began to work passionately on their own caves. Enthusiasm was essential because of the great toil it took to create the caves. Just as 32nd Army had only two bulldozers to make airfields, it had no mechanized tunneling equipment at all. Besides lacking cutting equipment, 32nd Army also lacked construction materials. It had no cement, no ironware, and no dynamite. The units had to rely entirely on wooden beams that they obtained themselves to shore up their shafts. This was not necessarily easy because there were no forests in the south of the island where the troops were now stationed. Pine forests were abundant in the mountainous north, however, so each unit was assigned its own lumbering district in the north. Several hundred men from each division were detailed as its lumbering squad. The problem remained, however, of how to move the several million logs that were needed over the 40 or so miles from the forests to the forts. With no railroads and the use of trucks limited by a shortage of gasoline, the solution was for each unit to cut its own logs, then transport them in small native boats called sabenis. The divisions acquired 70 of these, which then plied the waters steadily from north to south. In January 1945, however, the Leyte-based B-24s that began flying over daily for reconnaissance also began strafing the boats. So the waterborne delivery of logs had to be switched from day to night, greatly lowering efficiency.

Ushijima aimed to prolong the fight from these positions and decided to destroy the indefensible Yontan and Kadena airfields to prevent their use by the enemy, effectively ending the ineffective air defense strategy initially devised by Tokyo. Meanwhile, Admirals Nimitz and Spruance were preparing for Operation Iceberg, the invasion of Okinawa. Given the expectation that the capture of Iwo Jima and recent air assaults on Japan would concentrate enemy air power around the Empire's core, which would respond aggressively to any attacks on Okinawa, the Americans needed to first neutralize or eliminate enemy air facilities in the Ryukyus, Kyushu, and Formosa to achieve air superiority over their objective.

As a result, all available carrier-based and land-based air forces were tasked with this operation, including Admiral Mitscher’s Task Force 58, General Kenney’s Far East Air Forces, Admiral Hoover’s Central Pacific Forward Area, and General Arnold’s 20th Air Force. From the 20th Air Force, General LeMay’s 21st Bomber Command was assigned to attack Okinawa before moving on to Kyushu and other vulnerable locations in the home islands. Meanwhile, Brigadier-General Roger Ramey’s 20th Bomber Command, supported by General Chennault’s 14th Air Force, focused on neutralizing Formosa. Aircraft from the Southwest Pacific Area were also set to conduct searches and continuous strikes against Formosa as soon as conditions on Luzon allowed. Additionally, the British carriers of Vice-Admiral Bernard Rawlings’ Task Force 57 were tasked with neutralizing air installations on the Sakishima Group in the ten days leading up to the landings. Once air superiority was achieved, Spruance’s 5th Fleet was to land Lieutenant-General Simon Buckner’s 10th Army, which included Major-General John Hodge’s 24th Corps and Major-General Roy Geiger’s 3rd Amphibious Corps. The 24th Corps comprised the 7th and 96th Divisions, while the 3rd Amphibious Corps included the 1st and 6th Marine Divisions. As the Commanding General of Expeditionary Troops, Buckner also oversaw the 27th and 77th Divisions and the 2nd Marine Division for special operations and reserve purposes. Furthermore, the 81st Division was held in area reserve. In total, Buckner commanded a force of 183,000 troops, with 116,000 designated for the initial landings. The plan called for Major-General Andrew Bruce’s 77th Division to first secure amphibious bases in the Kerama Islands on March 26, with one battalion further securing Keisejima five days later to establish a field artillery group there.

On April 1, following a demonstration by the 2nd Marine Division in southern Okinawa, the main landings were set to take place. The 24th Corps and the 3rd Amphibious Corps would land simultaneously on the west coast beaches north and south of Hagushi. After landing, both corps were to quickly advance across the island, capturing the airfields in their designated areas before securing all of southern and central Okinawa. Subsequently, Buckner’s forces were to invade and secure Iejima and northern Okinawa. Once this was achieved, there were tentative plans to launch an invasion of Kikaijima with the 1st Marine Division and Miyako Island with the 5th Amphibious Corps. For the invasion, Spruance relied on a Covering Force under his command, along with Admiral Turner’s Joint Expeditionary Force. This force included Admiral Blandy’s Amphibious Support Force, which comprised minesweepers, UDTs, and escort carriers; Rear-Admiral Morton Deyo’s Gunfire and Covering Force, consisting of ten battleships and eight heavy cruisers; Rear-Admiral Lawrence Reifsnider’s Northern Attack Force, responsible for landing the 3rd Amphibious Corps; and Rear-Admiral John Hall’s Southern Attack Force, tasked with landing the 24th Corps. Similar to Iwo Jima, Okinawa had endured multiple air attacks since October 1944 as part of the preliminary operations for the landings on Leyte, Luzon, and Iwo Jima that we previously discussed. These operations also included air strikes aimed at neutralizing Japanese air power on Formosa. Throughout February and March, Mitscher’s carriers and LeMay’s B-29s brought the conflict back to the Japanese home islands with a series of strikes that caused significant damage and instilled fear in the population.

On March 1, Task Force 58 launched the first strike of the month against the Ryukyus, targeting Amami, Minami, Kume, Tokuno, and Okino, as well as Okinawa. This operation resulted in the destruction of 41 planes, the sinking of eleven vessels, damage to five others, and significant harm to island facilities. In between the main assaults on Japan, the superfortresses frequently targeted key sites in the Ryukyus, leading the beleaguered Japanese forces to refer to these missions as the "regular run." Throughout March, aircraft from the Southwest Pacific and the Marianas conducted nearly daily operations over the Ryukyus and surrounding waters, searching for Japanese shipping and contributing to the isolation of Okinawa by sinking cargo ships, luggers, and other vessels, while American submarines intensified the blockade around the Ryukyus. Meanwhile, after completing extensive training and rehearsals, Task Forces 51 and 55 gathered at Leyte, Task Force 53 assembled in the Guadalcanal-Russells area, and the rest of the 5th Fleet convened at Ulithi. On March 12, Reifsneider’s convoy, carrying the 3rd Amphibious Corps, was the first to depart, successfully reaching Ulithi nine days later. On March 18, the tractor group transporting the 77th Division began its journey from Leyte to the Kerama Islands. On the same day, Mitscher’s carriers targeted 45 airfields in Kyushu, claiming the destruction of 102 Japanese planes, damaging or destroying 275 on the ground, sinking six vessels, and damaging three more. In response, Admiral Ugaki’s 5th Air Fleet launched a counterattack against the carriers Enterprise, Intrepid, and Yorktown, inflicting minor damage while losing 33 aircraft.

The next morning, after locating the majority of the Combined Fleet at Kure, Mitscher dispatched 436 aircraft to target naval installations and shore facilities in the Inland Sea. At 06:50 three C6N Saiun “Myrt” recon planes discovered Task Force 58, and by 07:00 Captain Genda Minoru’s elite, handpicked 343rd Kokutai had scrambled 63 advanced Kawasaki N1K2-J “George” Shiden-Kai fighters from Shikoku to intercept the Americans. Minutes later, Genda’s powerful Shiden-Kais “waded into the Hellcats and Corsairs as if the clock had been turned back to 1942.” Soon the 343rd Kokutai was engaged in a wild maelstrom with 80 US fighters, including VF-17 and VBF-17 Hellcats from Hornet and VMF-112 Corsairs from Bennington. For once the Japanese broke about even, losing 24 fighters and one scout plane to the Americans’ 14 fighters and 11 bombers. Nevertheless, Genda’s expert but outnumbered 343rd Kokutai proved unable to blunt the American onslaught.

Despite facing a formidable intercepting force, they managed to inflict damage on 18 Japanese warships, including the battleships Yamato, Ise, Hyuga, and Haruna, as well as six aircraft carriers. Additionally, one incomplete submarine was destroyed, 97 enemy planes were shot down, and 225 were either destroyed or damaged at Japanese airfields. In response, Ugaki launched a kamikaze counterattack that successfully struck the carriers Wasp and Franklin, causing significant damage and forcing Franklin to head to Pearl Harbor immediately. As Task Force 58 slowly withdrew the afternoon of March 20, a damaged Zero crashed destroyer Halsey Powell, killing 12 and wounding 29. Shortly afterwards friendly anti-aircraft fire started fires aboard Enterprise. At 23:00 eight Japanese torpedo planes unsuccessfully attacked the carriers, while three overnight snoopers were splashed by anti-aircraft fire. Between March 17 and March 20 Ugaki had committed 193 aircraft to battle and lost 161. On March 21 Ugaki dispatched a 48-plane strike, including 16 G4M “Betty” bombers, carrying the very first Ohka (“Cherry Blossom”) suicide missiles. However the combat air patrol (CAP) of 150 Hellcats and Corsairs repulsed them. Franklin, Wasp, and Enterprise, all damaged, steamed to Ulithi as a reorganized Task Group 58.2. Except for April 8–17, when Task Group-58.2 was briefly reestablished, Task Force 58 strength would remain at three Task Groups throughout Iceberg’s duration. Ugaki’s 5th Air Fleet was meanwhile effectively incapacitated for several weeks, but Ugaki nevertheless reported five carriers, two battleships, and three cruisers sunk, which IGHQ found scarcely credible.

Meanwhile, the Mine Flotilla departed Ulithi on March 19, followed two days later by the rest of Task Force 52 and Task Force 54 to support the Kerama operation. On March 23, to prepare for the imminent minesweeping operations of Iceberg, Task Force 58 conducted extensive bombing raids on all known installations in Okinawa, resulting in significant damage and the sinking of 24 vessels and damage to three others over the following five days. Furthermore, Admiral Lee's battleships traversed the cleared area and opened fire on Okinawa, sinking an additional two vessels. With this naval and air support, Blandy’s minesweepers and UDTs successfully cleared the route for Rear-Admiral Ingolf Kiland’s Western Islands Attack Group by nightfall on March 25. Their primary opposition in the following two days consisted of a series of kamikaze attacks, which caused damage to the battleship Nevada, light cruiser Biloxi, four destroyers, two destroyer minelayers, one minesweeper, and two transports, while the destroyer Halligan was sunk by mines.

The next morning, supported by naval gunfire and carrier aircraft, Bruce initiated his first landings. The 3rd Battalion, 305th Regiment landed on the southern beaches of Aka Island, facing sporadic resistance. Meanwhile, the 1st Battalion, 306th Regiment landed unopposed on Geruma Island, which was quickly secured. The 2nd Battalion, 306th Regiment achieved even faster success at Hokaji Island, while the 1st Battalion, 305th Regiment invaded Zamami Island with light resistance. The 2nd Battalion, 307th Regiment encountered minor opposition as it took Yakabi Island. The Fleet Marine Force Amphibious Reconnaissance Battalion scouted Keisejima and found no enemy presence.

After encountering some resistance, the units on Aka and Zamami pushed back the enemy garrisons, securing two-thirds of Aka by nightfall and successfully repelling a strong counterattack on Zamami that night. Simultaneously, Deyo’s warships and Blandy’s carriers began bombarding the demonstration beaches, while minesweepers cleared progressively larger areas around Okinawa, although the minesweeper Skylark was sunk by mines. By March 27, the remaining enemy forces on Aka and Zamami were finally eliminated, and a company took Amuro Island without opposition. Additionally, a company from the 307th moved to Kuba Island, which was quickly secured.

At the same time, Bruce continued his main landings, with the 1st and 2nd Battalions of the 306th Regiment landing on the west coast of Tokashiki Island, facing minimal opposition. As the two battalions advanced north along narrow trails toward Tokashiki town, the 3rd Battalion landed to secure the southern part of the island. On March 28, they reached the town, clearing the entire island and concluding the Kerama operation. 

In Kerama, "Island Chain between Happiness and Good," the Japanese tradition of self-destruction emerged horribly in the last acts of soldiers and civilians trapped in the hills. Camping for the night of March 28 a mile from the north tip of Tokashiki, troops of the 306th heard explosions and screams of pain in the distance. In the morning they found a small valley littered with more than 150 dead and dying Japanese, most of them civilians. Fathers had systematically throttled each member of their families and then disemboweled themselves with knives or hand grenades. Under one blanket lay a father, two small children, a grandfather, and a grandmother, all strangled by cloth ropes. Soldiers and medics did what they could. The natives, who had been told that the invading "barbarians" would kill and rape, watched with amazement as the Americans provided food and medical care; an old man who had killed his daughter wept in bitter remorse. Only a minority of the Japanese, however, were suicides. Most civilians straggled into American positions, worn and dirty. In all, the 77th took 1,195 civilian and 121 military prisoners. This operation resulted in the deaths of 530 Japanese soldiers, 121 captured, and the neutralization of over 350 suicide boats, with American losses totaling 31 killed and 81 wounded.

While this initial operation was underway, the tractor groups of the Southern and Northern Attack Forces left their staging areas in Luzon and Ulithi on March 25, followed by the rest of Spruance’s fleet two days later. On March 26 and 27, Rawlings’ Task Force 57 conducted a series of strikes on the Sakishima Islands, primarily targeting Miyako. Meanwhile, after a 250-plane raid on the Mitsubishi plant in Nagoya on March 24, LeMay sent 165 B-29s from the 73rd and 314th Bombardment Wings to attack the Kyushu airfields on March 27, facing minimal resistance as they caused significant damage to the Tachiarai Army Airfield, the Oita Naval Airfield, and the Omura aircraft plant. Other bombers from the 313th Bombardment Wing laid aerial mines in the Shimonoseki Strait. The Japanese responded with a raid on Spruance’s naval units using aircraft and suicide boats on the night of March 28, resulting in one LCM being destroyed and one cargo ship damaged. On March 29, Mitscher launched another strike against Kyushu, but poor weather conditions led to only minor damage, with 12 vessels sunk and one damaged. By this point, the “largest assault sweep operation ever executed” had cleared the Hagushi beach approaches in 75 sweeps, with minesweepers clearing 3,000 square miles of coastal waters. The following morning, as Task Force 58 once again targeted Okinawa, Deyo’s ten battleships and eleven cruisers advanced to bombard Okinawa’s defenses and demolish coastal seawalls with increased intensity. At the same time, the 314th sent 12 planes to attack the Mitsubishi engine works in Nagoya overnight. The next day, LeMay dispatched 152 B-29s for his second assault on Kyushu, completely destroying the Tachiarai machine works and heavily damaging the Omura airstrip.

On March 31, back in Okinawa, the final underwater demolition operation off the Hagushi beaches was underway while the 420th Field Artillery Group was successfully positioned on Keisejima, prompting a strong reaction from Ushijima’s artillery. That morning, a Ki-43 fighter crashed into Admiral Spruance’s flagship, the Indianapolis, resulting in the deaths of nine crew members and severely damaging a shaft, which ultimately compelled Spruance to transfer his flag to the battleship New Mexico. Meanwhile, the frogmen completed their last demolition operations at Hagushi, and the final preliminary bombardment of Okinawa and the Sakishima Islands was executed successfully. By the end of the month, over 13,000 large-caliber shells had been fired in the shore bombardment, and approximately 3,095 sorties had been conducted against the Ryukyus. However, effective Japanese concealment prevented significant damage to Ushijima’s defenses. As night fell, a vast fleet of transports, cargo ships, landing craft, and warships navigated the final miles of their long journey, successfully meeting off the Hagushi beaches in the East China Sea before dawn on April 1. While Turner’s forces prepared for the landing, a fire support group consisting of 10 battleships, 9 cruisers, 23 destroyers, and 177 gunboats began the pre-landing bombardment of the beaches at 05:30, firing a total of 44,825 rounds of shells, 33,000 rockets, and 22,500 mortar shells. In response, the Japanese launched some scattered kamikaze attacks on the convoys, successfully hitting the transport Hinsdale and LST 884. At 07:45, carrier planes from Task Force 58 and Blandy’s carriers targeted the beaches and nearby trenches with napalm. Fifteen minutes later, the first wave of amphibious tanks advanced toward the shore at four knots, followed closely by five to seven waves of assault troops in amphibious tractors.

Alongside the primary landings, Major-General Thomas Watson's 2nd Marine Division staged a feigned landing on the southeast coast of Okinawa, near Minatoga, aiming to distract the enemy's reserves in that region. Meanwhile, on the main front, supported by rocket fire from LCI gunboats and artillery fire from Keisejima, a nearly continuous line of landing craft advanced toward the beaches at 08:20. Encountering no resistance, the first waves began to land on their designated beaches at 08:30, with additional troops following closely behind. Within an hour, Geiger’s 3rd Amphibious Corps had successfully landed the assault elements of the 6th and 1st Marine Divisions north of the Bishi River, while Hodge’s 24th Corps disembarked the 7th and 96th Divisions to the south of the river. The lack of significant opposition, coupled with the rapid disintegration of the untrained 5473 airfield service troops of the 1st Specially Established Regiment under heavy air and artillery bombardment, created a sense of foreboding among the men, prompting them to scout the area cautiously. As before, the enemy's primary response consisted of kamikaze attacks on naval units, resulting in damage to the battleships West Virginia and Tennessee, the British carrier Indefatigable, destroyers Prichett and Vammen, the British destroyer Ulster, the destroyer minelayer Adams, and four other vessels. Returning to Okinawa, after ensuring they were not walking into a trap, the troops began advancing inland while tanks and other support units were brought to the beaches.

In the north, Major-General Lemuel Shepherd’s 6th Marine Division deployed Colonel Merlin Schneider’s 22nd Marines on the isolated Green Beaches and Colonel Alan Shapley’s 4th Marines on the Red Beaches near Yontan Airfield. The 4th Marines advanced toward Yontan, encountering only scattered resistance, and quickly secured the objective east of the airfield by 13:00. Meanwhile, Schneider’s 3rd Battalion moved through Hanza without opposition, but the 2nd Battalion's progress was hindered as it needed to protect its exposed flank, prompting the 22nd Marines to quickly commit its reserve battalion to maintain their momentum. To the south, Major-General Pedro Del Valle’s 1st Marine Division landed Colonel Edward Snedeker’s 7th Marines on the Blue Beaches and Colonel John Griebel’s 5th Marines on the Yellow Beaches just north of the Bishi River. By 09:45, the 7th Marines on the left had advanced through the village of Sobe, their primary objective, while the 5th Marines were positioned 1,000 yards inland. At this point, it was decided to land the reserve battalions of both regiments, along with Colonel Kenneth Chappell’s 1st Marines. With forces arranged in depth and reserves positioned to the right and left, Del Valle’s units continued to advance steadily over the rolling terrain as the 11th and 15th Marines artillery units were also being landed. At 13:30, the 4th Marines resumed their advance, facing light resistance on the left but becoming overextended on the right while trying to maintain contact with the 7th Marines. As a result, Shapley landed his reserve battalion to fill this gap, while Shepherd also deployed his reserve 1st Battalion, 29th Marines, to secure the critical northern flank, allowing the 22nd Marines to keep advancing eastward.

Meanwhile, further south, Major-General Archibald Arnold’s 7th Division disembarked Colonel Frank Pachler’s 17th Regiment on the Purple Beaches just south of the Bishi River and Colonel John Finn’s 32nd Regiment on the Orange Beaches in front of Kadena Airfield. Both regiments quickly ascended the gentle hills at the landing sites and began advancing eastward. By 10:00, the 27th Regiment had patrols at Kadena Airfield, which was discovered to be empty; by 10:30, the front line was crossing the airstrip. Moments later, it advanced 200 yards beyond, heading towards Cholon. Simultaneously, the 32nd Regiment secured the southwestern edge of Kadena and continued along the road to Kozo. To the south, Major-General James Bradley’s 96th Division landed Colonel Michael Halloran’s 381st Regiment on the White Beaches in front of Sunabe and Colonel Edwin May’s 383rd Regiment on the Brown Beaches at the extreme southern flank. Both regiments moved eastward with the same ease as the other units that day, making significant progress towards Momobaru in the north and successfully capturing Chatan in the south. Additionally, all divisional artillery of the 24th Corps landed early; Hodge’s reserve regiments and battalions were successfully brought ashore, and by nightfall, direct-support battalions were in position. By the end of the day, over 60,000 men had landed, suffering only 28 dead, 27 missing, and 104 wounded, thereby establishing a beachhead 15,000 yards long and up to 5,000 yards deep in some areas.

Shepherd’s Marines paused for the night along a line stretching from Irammiya to the division boundary south of Makibaru, which the 1st Marine Division extended further south to Kadena. Meanwhile, the 7th Division advanced nearly three miles inland, destroying several pillboxes but losing three tanks to mines. The 96th Division secured positions along the river south of Chatan, on the elevated ground northwest of Futema, in the outskirts of Momobaru, and in the hills to the northwest and southwest of Shido. Although there were gaps in the lines in several areas, they were filled by reserve units or weaponry before nightfall. Thus, the Battle of Okinawa, seen by most as the final climactic battle of the Pacific War has only just begun.

As Gandalf the White once said “The board is set, the pieces are moving. We come to it at last, the great battle of our time.” The battle of Okinawa will become the bloodiest campaign America has ever fought. The soul crushing journey has just begun as the Americans end the last stand of the Japanese in the Pacific War.

- 175 - Pacific War Podcast - Visayas Offensive - March 25 - April 1 - , 1945

Last time we spoke about the fall of Iwo Jima. General Schmidt pushed through Japanese defenses, facing strongholds like Cushman’s Pocket and General Senda’s positions, with intense fighting and heavy casualties on both sides. Despite stubborn resistance, the Marines gradually advanced, employing tanks and artillery support. The Japanese, under General Kuribayashi, fought tenaciously, culminating in a final assault on March 26. After brutal combat, Iwo Jima was declared secured, but at great cost: 18,000 Japanese and over 6,800 American lives lost. Meanwhile, in New Britain, Australian forces continued their offensive, capturing strategic positions despite fierce enemy resistance. In the midst of a fierce conflict, Australian battalions advanced into enemy territory, capturing strategic positions while facing heavy resistance. Notable victories included the successful ambushes by the 2/7th Battalion and the capture of key locations like the But airfield. Despite facing fierce counterattacks from the Japanese, particularly at Slater’s Knoll, the Australians maintained their momentum. As the Japanese command faced internal crises, the Australians continued their relentless push, ultimately leading to significant territorial gains and weakening enemy forces.

This episode is the Visayas Offensive

Within northern Luzon, by mid-March, General Clarkson’s 33rd Division was exploring the western routes to Baguio. Colonel Volckmann’s guerrilla unit had taken control of San Fernando and was engaged in combat around Cervantes. Meanwhile, General Mullins’ 25th Division had advanced to Putlan, and General Gill’s 32nd Division was involved in a fierce battle at Salacsac Pass. Following the capture of Putlan, General Swift instructed Mullins to push through Balete Pass to secure the vital Santa Fe region. On March 12, the 27th and 161st Regiments began advancing north and northwest, successfully clearing the Minuli area and establishing a foothold on Norton Ridge by March 15. At the same time, the 35th Regiment initiated a broad maneuver around Balete Pass via the Old Spanish Road, but this was soon hindered by intense artillery and mortar fire from the positions of the 11th Independent Regiment. The road also required significant engineering efforts to support the outflanking force, leading Mullins to ultimately halt the 35th’s assault. However, General Konuma was unaware of this; fearing an outflanking maneuver from Carranglan, he had no choice but to keep around 3,000 of his best troops in this seemingly secure area. On March 15, Mullins ordered the reinforced 161st Regiment to launch a holding attack to the north while the majority of the 27th Regiment executed a flanking maneuver over Myoko Ridge, Mount Myoko, and Lone Tree Hill to encircle Balete Pass from the east. After regrouping at Putlan, the 35th was also tasked with capturing Mount Kabuto to subsequently advance northwest along Balete Ridge and connect with the 27th at Myoko.

Mullins launched a renewed offensive on March 16, facing stubborn resistance from the 161st as it gradually advanced toward Norton’s Knob, which was successfully captured by the end of the month. On March 22, the 27th began its flanking maneuver, with the 1st Battalion moving east into the elevated terrain south of Kapintalan by March 28, while the 2nd Battalion advanced nearly 3,750 yards up the wooded Myoko Ridge to the east. Meanwhile, the 35th's attempt to encircle the enemy via Kabuto started off well, reaching the northern slope of Balete Ridge on March 22. However, Konuma's recently arrived reinforcements launched a series of strong counterattacks and harassment raids, forcing the 35th to withdraw by March 28. With the other two regiments stretched thin and unable to penetrate the enemy's main defenses, Mullins ordered the 35th to position itself between the 27th and 161st Regiments to assault Highley Ridge from the east. By the end of March, the 161st was advancing northeast along Highley Ridge toward Crump Hill, which finally fell on April 8, bringing the advance to a halt. The 35th supported this effort with an attack on Kapintalan, which was ultimately captured by April 21. Meanwhile, the 27th continued to struggle through the challenging terrain of Myoko Ridge against fierce opposition, not reaching Woody Hill until April 12. This slow progress allowed Konuma to reinforce the Myoko sector with four understrength infantry battalions. Nevertheless, the brave soldiers of the 27th Regiment persevered, securing the Pimple on April 15 and advancing an additional 350 yards northeast by April 21.

Looking west, Clarkson aimed to advance battalion combat teams toward Baguio via Route 11, the Galiano road, and the Tuba Trail. However, Swift declined to approve such ambitious plans, limiting the 33rd Division to a more restrained offensive. Although dissatisfied, Clarkson continued the attack along Route 11, managing to reach Camp 3 by the end of March. In the central area, patrols faced no opposition as they approached within a mile of Galiano, but other patrols discovered increasing signs that the Japanese were preparing to defend the Tuba Trail vigorously. Eventually, a robust reconnaissance force secured Bauang on March 19, with patrols then moving east to occupy Naguilan four days later and Burgos by the month's end. Meanwhile, at Salacsac Pass, the 127th Regiment fought from Hill 502 to Hill 504 against fierce resistance, while Gill sent the 2nd Battalion, 128th Regiment up the trail from Valdez toward Imugan, where they were ultimately halted by vigilant Japanese forces. By March 23, the 1st Battalion of the 127th Regiment reached the crest of Hill 504; the 2nd Battalion advanced past it to Hill 505; and the 3rd Battalion managed to position one company at the base of Hill 507D. However, with its forces stretched thin and dwindling, the 127th was unable to capitalize on its seemingly advantageous position, allowing General Iwanaka to launch a strong counterattack on Hill 507D that successfully repelled the 3rd Battalion. As a result, Gill decided to withdraw that unit and the stalled 2nd Battalion, 128th Regiment, while the majority of the 128th relieved the 127th in the Hill 502 sector.

Beginning on March 25, the 128th Regiment advanced aggressively eastward, successfully capturing the previously overlooked Hill 503, fully securing Hill 504, and expanding its control over Hill 505 by the month's end. However, on the night of March 31, Iwanaka launched a daring counterattack, reclaiming Hill 504 and nearly taking all the territory east of Hill 502. By April 4, both the 127th and 128th Regiments had sustained significant casualties and could no longer continue the offensive. Consequently, Swift had to order the 33rd Division to relieve the beleaguered 126th Regiment in the Ambayabang and Arboredo River valleys, allowing this unit to reposition north of the Villa Verde Trail to execute a flanking maneuver along the Miliwit River valley. Fortunately for Clarkson, General Krueger persuaded MacArthur to free the 129th Regiment from its duties in Manila, sending it to bolster the now overstretched 33rd Division. Once the rest of the 37th Division arrived at the Baguio front, which Krueger anticipated would happen in early April, Swift could initiate a two-division assault on Baguio. In the meantime, Clarkson promptly dispatched the 129th to Burgos, and by April 1, it had advanced to Salat. 

The Japanese opposing the reinforced 33d Division were no longer in the shape they had been at the end of February. The 58th IMB and the 23d Division had both suffered heavy losses during March, losses that probably stemmed largely from lack of food and medical supplies rather than from combat action. By mid-March Japanese supply problems on the Baguio front had progressed from bad through worse to impossible. First, supplies had moved westward over the new Baguio-Aritao supply road far more slowly than anticipated, a development attributable in large measure to Allied Air Forces strikes on that road and along Route 5 north and south of Aritao. Second, operations of the 66th Infantry, along Route 11 north from Baguio, and the activities of the 11th Infantry, , in the Cagayan Valley, had made it virtually impossible for the Japanese to bring any food into the Baguio area from the north. Third, the Japanese tried to do too much with the limited amount of supplies available on the Baguio front. They were attempting to supply 23d Division and 58th IMB troops along the MLR; send certain military supplies north up Route 11 for the 19th Division; feed 14th Area Army headquarters and a large civilian population in Baguio; and establish supply dumps north and east of the city against the time of eventual withdrawal. Almost inevitably the principal sufferers were the front-line troops. By mid-March the best-fed Japanese combat troops on the Baguio front were getting less than half a pound of rice per day as opposed to a minimum daily requirement of nearly two and a half pounds. Before the end of the month the troops on the MLR were down to less than a quarter of a pound of rice a day. Starvation and diet-associated diseases filled hospitals and sapped the strength of the combat units. Generally, effective frontline strength was far lower than reported ration strength indicated. Medical supplies were consumed rapidly, and by the end of March, for example, there was virtually no malaria phophylaxis left in Baguio area hospitals. Looking upon the situation on the Baguio front with frank pessimism, Yamashita in mid-March directed inspection of terrain north, northeast, and east of the city with a view toward preparing a new defense line. His attitude became even plainer when, on or about 30 March, he ordered Japanese civilians and the Filipino puppet government to evacuate Baguio. Indeed, the future on the Baguio front was so bleak by the end of March that almost any other army would have withdrawn to new defenses forthwith, thereby saving troops for future battle. But not so the Japanese. Yamashita decided that the existing MLR would be held until the situation became hopeless. At the end of March that portion of the MLR held by the 23d Division was still intact, and the 58th IMB was busy deploying additional strength along its section of the line. One independent infantry battalion was on high ground north of Route 9 at Sablan; and another held defenses at Sablan. A reinforced company was at Burgos and, less that company, another independent infantry battalion held reserve positions at Calot, a mile and a half southeast of Sablan. One understrength battalion was responsible for defending the rough terrain from Sablan six miles south to Mt. Apni, where a tie-in was made with the right flank of the 23d Division. Maj. Gen. Bunzo Sato, commanding the 58th IMB, expected that the emphasis of any Allied drive in his sector would come along Route 9, but he did not neglect the other approach in his area, the Galiano road. Since the understrength battalion stationed astride the road was not strong enough to withstand a concerted attack, he directed his main reserve force, the 1st Battalion of the 75th Infantry, 19th Division, to move west out of Baguio to defenses at Asin. This step left in Baguio a reserve force of roughly three provisional infantry "battalions," which together probably could not muster over 750 effectives.

In the Salacsac area, as casualties in the western pass were rapidly increasing and Allied air and artillery strikes made it nearly impossible for the 2nd Tank Division to transport supplies, Iwanaka concluded that his forward positions were nearly untenable. He began planning to redeploy forces to defend the eastern pass. Consequently, when the 126th Regiment launched its new offensive on April 5, it faced unexpectedly light resistance, quickly capturing Hills 518 and 519 within two days and cutting off a Japanese supply route leading north from Hill 504 across the eastern slopes of Hill 519 and up Mount Imugan. However, Iwanaka swiftly recognized the emerging threats and sent reinforcements to intercept the 126th’s advance, delaying the capture of Hills 511 and 512 until March 13 and effectively halting further progress. At the same time, the reorganized 128th Regiment resumed its assault eastward on April 7, successfully retaking the Hill 504-505 sector and capturing Hill 506 by April 10. The following week, the 128th fought tenaciously to secure this elevated ground against fierce resistance, managing to push all the way to Hills 506B, 507C, and 507D with their remaining strength, nearly securing the western pass by April 17. Meanwhile, after the fall of San Fernando, General Krueger instructed Volckmann to advance inland along Route 4 toward Bontoc. However, the Provisional Battalion established at Cervantes could only withstand the relentless enemy pressure until April 4, when it was ultimately forced to retreat into the hills northwest of the town. Consequently, Volckmann had to quickly deploy the 121st Regiment to barrio Butac in preparation for an eastward push along Route 4.

After a week of intense back-and-forth combat, this elite guerrilla unit succeeded in establishing footholds along the northern parts of Lamagan and Yubo Ridges. Over the next few days, the 121st made slow and arduous progress, ultimately gaining control of Route 4 nearly to the southeastern edge of Bessang Pass by mid-April. Further south, by mid-March, General Wing’s 43rd Division had effectively secured the Antipolo sector, while General Hurdis’ 6th Division was advancing well toward Mount Baytangan. At this point, General Hall’s 11th Corps assumed responsibility for operations against the Shimbu Group, now rebranded as the 41st Army. However, he quickly decided to maintain the offensive against General Yokoyama’s left flank, with the 20th and 1st Regiments focusing on an eastward push alongside the 43rd Division. Meanwhile, General Noguchi had completed his withdrawal to the Sugarloaf Hill-Mount Tanauan line, where he would receive reinforcements from elements of the Kogure Detachment. Simultaneously, General Kobayashi was struggling to stabilize his left flank, bolstered by one reserve battalion. On the morning of March 15, the American offensive resumed, with the 103rd Regiment continuing its assaults on Benchmark 7 Hill to secure Route 60-A, while the 172nd Regiment launched its initial attacks toward Sugarloaf Hill, facing fierce resistance. On March 17, the 1st Regiment renewed its advance toward Baytangan, initially making good progress and digging in about a mile west-southwest of the mountain’s summit. However, during the night, a barrage of mortar fire followed by an infantry counterattack forced the Americans to retreat in disarray.

As a result of this setback, the 1st Division began to advance eastward more cautiously, facing determined resistance and heavy mortar fire. By March 22, it was only slightly closer to Baytangan's crest than it had been five days earlier. The 20th Regiment on the left also encountered strong resistance, managing to reach a point a mile and a half west of Baytangan by March 22. At the same time, a company maneuvering to the north established a foothold on a wooded ridge overlooking the Bosoboso Valley. Meanwhile the 103d Infantry finally overran the defenses on Benchmark 7 on 18 March, killing about 250 Japanese in the process. The Japanese battalion there had delayed the 103d's attack toward Mt. Tanauan until the morning of 18 March, but by evening of that day the regiment's troops had begun swarming up the bare, rocky, southern and southwestern slopes of the mountain.

Over the next three days, American forces slowly advanced through a complex of caves and bunkers until they secured the mountain's summit, while other units captured Benchmark 23 Hill and patrolled northward into the southeastern part of the Bosoboso Valley. By March 19, the 172nd Division was halted, containing Sugarloaf to the west. They bypassed it to the north and east, initiating new assaults toward Mounts Yabang and Caymayuman, making significant progress to the east but less so to the north by March 22. Despite concerns that Hall’s four exhausted regiments might lack the strength to turn the 41st Army’s left flank, the ongoing pressure and the failure of previous counterattacks ultimately compelled Yokoyama to order his threatened units to withdraw to new positions east of the Bosoboso River. Therefore, when the 6th and 43rd Divisions resumed their attacks on the morning of March 23, the withdrawal was already in full progress.

Over the next three days, the 1st and 20th Regiments faced only scattered and disorganized resistance, allowing them to establish positions over a mile north and south of Baytangan along the ridgeline that overlooks the Bosoboso Valley. Meanwhile, the 172nd Regiment successfully captured Mount Yabang and most of Mount Caymayuman, while the 103rd Regiment advanced quickly northward, taking barrio New Bosoboso, Mount Balidbiran, and Benchmark 21 Hill. On March 27, the 1st Regiment secured the crest of Baytangan, and the 172nd Regiment eliminated the last organized opposition at Sugarloaf Hill. With Yokoyama’s left flank collapsing, Hall could focus on capturing Wawa Dam and destroying the remaining elements of the Kobayashi Force west of the Bosoboso River, a mission assigned to the 6th Division. During this initial offensive, approximately 7,000 Japanese soldiers were killed since February 20, while American casualties included 435 killed and 1,425 wounded. Hurdis’ initial strategy for capturing Wawa Dam involved the 1st and 20th Regiments advancing northward to clear Woodpecker Ridge and Mount Mataba, while the 63rd Regiment conducted diversionary attacks on the western slopes of Mataba. This new offensive began on March 28 but quickly faced intense small arms, machine-gun, and mortar fire, leading to a back-and-forth struggle against fierce enemy resistance. By April 3, the 20th Regiment had advanced less than half a mile toward Mataba, and the 1st Regiment had gained only 250 yards to the north. General Hurdis had hoped his attack, directed against the Kobayashi Force southern flank, would be far more successful, but the Kobayashi Force, rapidly and efficiently, had reoriented its defenses, which it had laid out primarily to face an attack from the west. The force's two remaining provisional infantry regiments, the Central and Right Sector Units, were still relatively intact, and the Central Sector Unit, bearing the brunt of the 6th Division's offensive, had recently been reinforced by remnants of the Left Sector Unit and elements of the Shimbu Group Reserve. Other factors bearing on the 6th Division's slow progress were the declining strength and deteriorating combat efficiency of its infantry regiments. The 20th Infantry could muster only 2,085 effectives on 3 April; some of its rifle companies were reduced to the combat strength of platoons. The situation within the 1st Infantry, with an effective strength of 2,150, was little better. As of 3 April the commanders of both regiments rated their units' combat efficiency only as "fair," the lowest ranking of three terms each had employed since the Lingayen Gulf assault.To bolster protection for Hurdis’ right flank, the 103rd Regiment also captured Hill 1200 on the east bank of the Bosoboso River by the end of the month.

Due to the slow progress of Hurdis’ offensive, on April 5, Hall assigned General Cunningham’s Baldy Force, which consisted of the 112th Cavalry Regiment and the recently arrived 169th Regiment, to take control of the area north of Mount Oro. This move would free up most of the 63rd Regiment to support the 20th Regiment and continue the assault north toward Mataba, while the 1st Regiment maintained its position along Woodpecker Ridge. From April 6 to 9, the 63rd made only limited progress to the east; however, on April 10, it shifted its focus to an offensive on the western slopes of Mataba, quickly securing the southwestern quarter of the mountain with minimal resistance. In response, Kobayashi promptly redirected his forces back to Mataba from the north-south ridge to prevent the 63rd from reaching the mountain’s summit until April 17. At the same time, the 1st Regiment resumed its advance along Woodpecker Ridge but again faced strong enemy opposition, resulting in only limited gains. Looking further south, by March 23, the 187th Glider Regiment and the 511th Parachute Regiment had advanced to Santo Tomas and Tanauan but were unable to completely clear these areas. Meanwhile, the 158th Regiment secured Balayan, Batangas, and the Calumpan Peninsula, pushing toward Mount Macolod, where they were ultimately halted by significant forces from the Fuji Force. At this stage, as Krueger planned to launch an offensive into the Bicol Peninsula using the 158th, he needed to relieve the 11th Airborne Division with the barely rested 1st Cavalry Division. This division quickly took control of the Santo Tomas-Tanauan area, while General Swing’s units maneuvered around the west side of Lake Taal to relieve the 158th at Macolod.

As a result, General Griswold renewed his offensive on March 24. The 187th attempted to attack Macolod but was unsuccessful. A task force composed of units from Swing’s other two regiments advanced quickly north toward Lipa, only to be halted at the hills southeast of the town. The 8th Cavalry captured Santo Tomas after a fierce battle and took Tanauan two days later. The 7th Cavalry advanced about five miles east into the corridor between Mounts Maquiling and Malepunyo, while the 12th Cavalry pushed along Route 21, moving about four miles beyond Los Baños. On March 27, Swing’s task force finally overcame the enemy defenses southeast of Lipa, but it was the 8th Cavalry that ultimately secured this strategic town two days later. Griswold’s successful offensive also forced around 2,000 troops from the Fuji Force to retreat along Route 21 and through the Santa Maria Valley to join Yokoyama’s forces in the mountains east of Manila. In response, Krueger devised a plan to prevent the potential influx of Japanese reinforcements around the eastern and northern shores of Laguna de Bay. He instructed Hall to clear the northern shore of the lake, block the Santa Maria Valley, and secure Route 21. While the 187th continued its assault on Macolod, Griswold ordered his other units to push eastward to secure Laguna de Bay and Tayabas Bay. Accordingly, on March 30, the 103rd Regiment advanced in small increments along the northern shore of Laguna de Bay, reaching Siniloan by April 4. The 12th Cavalry moved to Calauan and then south along a secondary road toward San Pablo, encountering strong enemy positions that wouldn’t be overcome until April 5. The 5th and 7th Cavalry Regiments fought through the Maquiling-Malepunyo corridor against determined but disorganized Japanese resistance, successfully occupying San Pablo by April 2. Additionally, elements of the 188th Glider Regiment pushed east through the mountain corridors, reaching Tiaong on April 3 and Lucena three days later.

By April 6, the 5th Cavalry and the 103rd Regiment had established contact at Pagsanjan, effectively isolating the 41st Army. The next day, patrols from the 11th Airborne Division headed north from Lucena, while 1st Cavalry Division patrols departed from Pagsanjan heading south. They successfully linked up at Lucban by April 10 and then advanced eastward to Mauban. At the same time, a company from the 188th traveled along Route 1 across the Bondoc Isthmus, reaching Atimonan on April 11. Griswold’s patrols also moved towards Mount Malepunyo, where the Fuji Force was preparing for its final stand. By April 16, preliminary assaults had concentrated enemy resistance around Mount Mataasna-Bundoc. Meanwhile, after a week of intense aerial bombardment, Brigadier-General Hanford MacNider’s 158th Regiment successfully landed at Legaspi Port with minimal opposition on April 1. They quickly secured the port and the nearby airfield, then advanced to Daraga before moving south along Route 1 to occupy the Sorsogon Peninsula, where they encountered machine-gun fire from the Mount Bariway-Busay Ridge. The following morning, the troops had to retreat east of Daraga, and in the coming days, the 158th faced tough fighting in the challenging, jungle terrain to overcome resistance in the Daraga area. Concerned about delays in occupying the Sorsogon Peninsula, MacNider landed his anti-tank company at Bacon on April 6, which occupied Sorsogon without opposition. Meanwhile, the 2nd Battalion continued its overland advance, reaching Bulan by April 12, where they targeted a significant Japanese concentration. Simultaneously, MacNider’s other two battalions attacked Camalig on April 11 and began their unsuccessful assault on enemy positions in the Cituinan Hills.

By April 1, the 188th had successfully eliminated the last organized resistance in the rugged hills south of Ternate. Meanwhile, the 2nd Battalion of the 151st Regiment launched an assault on Caballo Island on March 27 but could not fully dismantle the entrenched enemy positions until April 13. The Japanese in the pits and tunnels created an almost insoluble problem for the 2d Battalion, 151st Infantry. The Japanese had so emplaced their weapons, which included machine guns and mortars, that they controlled all approaches to the mortar pits but could not be reached by American artillery or mortar fire. When the 151st Infantry concentrated its mortar fire against the pits' entrances, the Japanese simply withdrew into the tunnels. When the American fire ceased--at the last possible moment before an infantry assault--the Japanese rushed out of the tunnels to man their weapons. Tanks were of no help to the American troops. From positions near the rim of the pits the tanks were unable to depress their guns sufficiently to do much damage to the Japanese. If the tanks tried to approach from above, they started sliding down Hill 2's slopes into the pits. No combination of tank, artillery, and infantry action proved of any avail, and the 151st Infantry had to give up its attempts to take the Japanese positions by assault. On 31 March engineers tried to pour diesel oil into one of the tunnels connecting the mortar pits, employing for this purpose a single ventilator shaft that was accessible to the 151st Infantry. Nothing came of the effort since it was impossible to get enough oil up the steep slopes of the hill to create a conflagration of significant proportions within the tunnels. Nevertheless, burning the Japanese out seemed to promise the only method of attack that would not risk the unduly heavy casualties of a direct infantry assault. No one, of course, wanted to throw away the lives of experienced troops on such an insignificant objective. Finally, the commander of the 113th Engineers, 38th Division, suggested pumping oil up the hill from the beach through a pipeline from a ship or landing craft anchored at the shore line. The Allied Naval Forces happily fell in with this idea and supplied the 151st Infantry with two oil-filled ponton cubes; the Allied Air Forces provided a 110-horsepower pump and necessary lengths of pipeline and flexible hosing; and the 592d Engineer Boat and Shore Regiment came through with an LCM to carry the pump and the ponton cubes. On 5 April over 2,500 gallons of diesel fuel were pumped into the pits and tunnels through the ventilator and were then ignited by white phosphorus mortar shells. "Results," the 38th Division reported, "were most gratifying." A huge flash fire ensued, followed by a general conflagration and several explosions. The engineers repeated the process on 6 and 7 April, and on the latter day carefully lowered two large demolition charges through the ventilator shaft and placed another at an accessible tunnel entrance. Set off simultaneously, the three charges caused an enormous volume of flames and several terrific explosions. For the next few days the 2d Battalion, 151st Infantry, tried to persuade a few Japanese who had lived through the holocausts to surrender and also executed a few infantry probing attacks. On 13 April a patrol entered the pits and tunnels, killed the lone surviving Japanese, and reported the positions cleared and secured. Following this, El Fraile was targeted, with Company F of the 151st and the 113th Engineers effectively neutralizing Fort Drum using gasoline and explosives. On April 16, troops from the 1st Battalion of the 151st Regiment attacked Carabao Island, facing no opposition.

Looking towards the Visayas, after capturing Palawan and Zamboanga, General Eichelberger set his sights on the Sulu Archipelago, where new airfields were to be established. On March 16, a reinforced company from the 162nd Regiment landed unopposed on Basilan Island and spent the next two days searching Basilan and nearby islets, finding no signs of Japanese forces. On April 2, the reinforced 2nd Battalion of the 163rd Regiment landed on Sanga Sanga Island, successfully clearing the Tawi Tawi Group by April 6. The remainder of the regiment made an unopposed landing near Jolo Town on April 9. Over the next two days, the Americans drove approximately 2,400 men of the 55th Independent Mixed Brigade from the heights immediately south and southeast of the town to secure a nearby airstrip. However, the Japanese retreated to more fortified hill masses further inland, where they had long prepared their defenses and began to resist fiercely. After initial attacks by Colonel Alejandro Suarez’s guerrillas failed to breach the Japanese positions, the 1st Battalion of the 163rd Regiment joined the fight and managed to overrun the enemy defenses by April 22.

On April 25, the 3rd Battalion launched an assault on Lieutenant-General Suzuki Tetsuzo’s final positions at Mount Tumatangus, which were ultimately subdued by May 2. However, the remaining Japanese forces continued to engage in guerrilla warfare. By this time, airfields in Zamboanga and Sanga Sanga had become operational to support the forthcoming invasion of Borneo.The first field at Zamboanga was a dry-weather strip 5000 feet long, completed on March 15 and immediately put to use by Marine Corps planes. The field, named Calarian Drome, could not answer the need for an all-weather strip 6000 feet long. Accordingly, engineers constructed a new strip, which the Marine aviators based there called Moret Field, about a mile to the east, and had it ready for all-weather operations by May 16. Used primarily by Marine Air Groups 12, 24, and 32, Moret Field was also employed by a 13th Air Force night-fighter squadron, an emergency rescue squadron, and 13th Air Force B-24s and P-38s staging through for strikes against Borneo. Marine Corps planes on March 16 executed the first support mission flown from a field in the Zamboanga area, covering the landing on Basilan Island. Later, Marine Corps planes from Zamboanga flew support for the Tawi Tawi and Jolo operations and undertook pre-assault bombardment and cover for the invasion of eastern Mindanao. While 13th Air Force planes executed most of the support for the invasion of Borneo, Marine Corps B-25s from Zamboanga also flew some missions. At Sanga Sanga Island there was a Japanese coral-surfaced strip about 2800 feet long. Engineers repaired and extended this strip to a length of 5000 feet by May 2, when fighters of the 13th Air Force began moving to Sanga Sanga from Palawan to provide close support for the initial landings on Borneo. These US Army planes were replaced in mid-May by units of the Royal Australian Air Force, which employed the all-weather Sanga Sanga field during later operations on Borneo. Finally, a Japanese field 3800 feet long on Jolo Island was repaired and used for aerial supply and evacuation operations in support of ground troops throughout the Sulu Archipelago.

Eichelberger's next target was the Central Visayan Islands. For the Panay-Guimaras-northern Negros operation, codenamed Victor I, he assigned General Brush’s 40th Division, excluding the 108th Regiment, which had recently been assigned to Leyte. The 40th Division departed Lingayen Gulf on March 15 aboard ships from Admiral Struble’s Task Group 78.3. After a brief stop at Mindoro, they arrived at Panay before dawn on March 18. Following a short bombardment by destroyers, the 1st and 3rd Battalions of the 185th Regiment landed unopposed about twelve miles west of Iloilo, where they were joined by Colonel Macario Peralta’s guerrillas, who already controlled much of the island. The 185th quickly expanded its beachhead against light, scattered resistance and began advancing along the coastal road toward Iloilo in the afternoon, forcing the 170th Independent Battalion to retreat to the mountainous interior. With Iloilo secured by March 20, G Company of the 185th Regiment successfully captured Inampulugan Island on March 22, while other elements of the regiment cleared the unoccupied Guimaras Island by March 23. Additionally, Brush decided to assign the 2nd Battalion of the 160th Regiment to garrison Panay alongside Peralta’s guerrillas. No pursuit of the 170th Independent Battalion was made, allowing the Japanese to continue their guerrilla activities until the end of the war.

Meanwhile, for the operation against northern Negros, Brush planned to launch an assault with the 185th Regiment on March 29, followed by the majority of the 160th Regiment the next day, while keeping the 503rd Parachute Regiment in reserve for potential airdrops. Opposing him, Lieutenant-General Kono Takeshi’s 77th Brigade had a total of 15,000 troops but was prepared to retreat into the mountains of north-central Negros for a prolonged defense, leaving only token forces in the coastal plain to delay American advances. On March 29, the 185th Regiment landed unopposed near Pulupandan and quickly secured a bridge over the Bago River. The 185th then spread north and east, with the 160th Regiment following, successfully securing nearly the entire coastal plain of northwestern Negros by noon on April 2. As they closed in on Kono's inner fortress, the Americans overran the main Japanese outposts while the 511th was landed to bolster the assault. On April 9, Brush launched his general offensive, with his three regiments advancing slowly into rugged terrain where the Japanese held significant defensive advantages. 

On June 4 General Kono, realizing that his remaining forces were incapable of further sustained effort, directed a general withdrawal deep into the mountains behind his broken defensive lines. The surviving Japanese dispersed into small groups seeking food and hideouts and trying to avoid contact with Colonel Abcede's guerrillas who, under the direction of the 503rd Parachute Regiment, took over responsibility for the pursuit of Kono's men. On June 9 the 503rd then relieved all elements of the 40th Division in northern Negros. By that date the Japanese had lost over 4000 men killed. Kono lost another 3350 troops, mainly from starvation and disease, before the end of the war. After the general surrender in August 1945, over 6150 Japanese came down from the mountains to turn themselves in, joining about 350 others who had been captured earlier. In all, about 7100 Japanese lost their lives in northern Negros, pinning down the equivalent of an American infantry division for over two months. The 40th Division's casualties for the operation, including those of the attached 503rd Parachute, totaled approximately 370 men killed and 1035 wounded. Meanwhile, Eichelberger’s final objective in the Central Visayas was Cebu, assigned to Major-General William Arnold’s Americal Division. For Operation Victor II, Captain Albert Sprague’s Task Group 78.2 was set to land the bulk of the division at Cebu City while Colonel James Cushing’s guerrillas secured the water sources.

Opposing them were Rear-Admiral Harada Kaku’s 33rd Naval Special Base Force and Major-General Manjome Takeo’s 78th Brigade, which together comprised approximately 14,500 troops, including the 173rd Independent Battalion and the 36th Naval Guard Unit stationed at Cebu City. Additionally, around 750 soldiers from General Kataoka’s 1st Division were positioned in northern Cebu. Although the command situation on the island was chaotic, General Suzuki’s 35th Army headquarters in Leyte had been evacuated by two large motorized landing barges between March 17 and 25. Taking control of all forces on Cebu, Suzuki appointed Manjome as the de jure commander in the Cebu City area while leaving Kataoka in charge of northern Cebu, as he prepared to retreat to Mindanao.

General Manjome designed his defenses so as to control--not hold--the coastal plains around Cebu City, and for this purpose set up defenses in depth north and northwest of the city. A forward line, constituting an outpost line of resistance, stretched across the first rising ground behind the city hills 2.5 to 4 miles inland. A stronger and shorter second line, the main line of resistance, lay about a mile farther inland and generally 350 feet higher into the hills. Back of this MLR were Manjome's last-stand defenses, centering in rough, broken hills 5 miles or so north of the city. Anticipating that American forces would attempt to mount wide envelopments of his defensive lines, Manjome set up one flank protective strongpoint in rugged, bare hills about 3.5 miles north of barrio Talisay, on the coast about 6 miles southwest of Cebu City, to block the valley of the Mananga River, a natural axis of advance for forces enveloping from the south and west. Similarly, he established strongpoints on his left to block the valley of the Butuanoan River, roughly 4 miles northeast of Cebu City. Against the eventuality that the American invading forces might land north of Cebu City and strike into the Butuanoan Valley, Manjome set up another flank protective position in low hills overlooking the beach at Liloan, 10 miles northeast of Cebu City. Manjome did not intend to hold the beaches, but at both Talisay and Liloan, the best landing points in the Cebu City region, he thoroughly mined all logical landing areas. The Japanese also constructed tank barriers along the shore line and planted tank traps and minefields along all roads leading inland and toward Cebu City. The inner defense lines were a system of mutually supporting machine-gun positions in caves, pillboxes, and bunkers. Many of these positions had been completed for months and had acquired natural camouflage. Manjome's troops had an ample supply of machine guns and machine cannon and, like the Japanese on Negros, employed remounted aircraft and anti-aircraft weapons. Manjome had some light and heavy mortars, but only a few pieces of light artillery. For the rest, however, Manjome's forces were far better supplied than Kono's troops in northern Negros.

After an uneventful journey, Task Group 78.2 and the Americal Division arrived off Cebu in the early hours of March 26. Following an hour of bombardment by three light cruisers and six destroyers from Admiral Berkey's Task Force 74, the leading waves of the 132nd and 182nd Regiments landed unopposed on beaches just north of Talisay at 08:30. However, the landing was chaotic, as Japanese mines just a few yards beyond the surf line disabled ten of the first fifteen LVTs. Fortunately for the Americans, Manjome had chosen to withdraw from the beaches to establish inland defenses, resulting in minimal casualties. Once they cleared the beach minefields by 10:00, Arnold’s leading units cautiously advanced through abandoned defenses toward the main highway to Cebu City, ultimately stopping for the night about a mile and a half south of their objective. The following day, the infantry secured Cebu City without opposition and on March 28 proceeded to clear Lahug Airfield and Hill 30 to the north.

The Americans began their assault on Go Chan Hill on March 29, during which Company A of the 182nd Regiment was completely annihilated by the explosion of an ammunition dump located in caves along the hill's eastern spur. Fueled by a desire for revenge, nearly the entire 182nd returned to the attack on March 30 and successfully captured Go Chan Hill. Meanwhile, the 132nd Regiment cleared the coastal plains area north to the Butuanoan River, further securing the city's water supply sources by April 2. Unopposed, troops from the 132nd also successfully landed on Mactan Island, quickly securing an airstrip. In the meantime, as guerrillas had already taken control of much of Masbate, the 2nd Battalion of the 108th Regiment successfully landed on the island by April 7. Facing minimal opposition, the Americans pursued the scattered Japanese remnants through the hills and jungles of Masbate, killing approximately 120 Japanese soldiers by May 4.

On March 29th, the Americans attacked Go Chan Hill, suffering heavy losses. Seeking revenge, they captured it the next day, securing water supplies and defeating Japanese forces in Masbate. Then in April, Allied forces advanced strategically, overcoming fierce Japanese resistance, securing key positions, and establishing airfields, culminating in significant victories across the Philippines.

- 174 - Pacific War Podcast - The Fall of Iwo Jima - March 18 - 25 - , 1945

Last time we spoke about the fall of Mandalay. Fierce battles raged over northern Luzon as General Clarkson's forces advanced, capturing key locations while Colonel Volckmann's guerrillas targeted enemy positions. The challenging terrain favored Japanese defenses, creating fierce resistance. Despite this, American troops steadily progressed, securing hills and towns. By mid-March, the 38th Division's relentless push led to significant Japanese losses. The brutal history of POW massacres fueled American resolve, leading to further victories in the region, American forces, led by Major-General Jens Doe were given the task of invading Palawan. Despite facing fortified defenses and rough terrain, the 41st Division advanced under artillery and air support. Meanwhile, in Burma, British-Indian forces clashed with the Japanese, capturing key positions and repelling assaults. As tensions rose in French Indochina, the Japanese executed a coup, disarming French forces and establishing puppet governments. The conflict intensified, reshaping the region's power dynamics.

Today we are picking up on Iwo Jima. By March 10, General Schmidt’s Marine forces had finally breached the determined enemy defenses to reach the northeastern shore of the island. However, there were still some Japanese strongholds to eliminate in the central and southern areas. One of these was Cushman’s Pocket, named after the commander of the 2nd Battalion, 9th Marines, and located around a devastated ridge overlooking the sea, which housed the stubborn resistance southwest of Hill 362C. The other stronghold, held by General Senda’s remaining troops, was established on March 11 after General Cates initiated his final push southeast toward the sea. Consequently, while Colonel Wensinger’s 23rd Marines advanced quickly to the coast, Colonel Lanigan’s 25th Marines struggled to make headway, as they were quickly halted by intense rocket, mortar, and small-arms fire from Senda’s pocket. Unbeknownst to the Americans, Senda had committed suicide on March 8 following the failure of his banzai counterattack, leaving the disorganized Japanese forces in the pocket without leadership. Meanwhile, General Rockey’s 5th Marine Division had advanced all the way to General Kuribayashi’s last line of defense in northern Iwo Jima, where the battered defenders were prepared to make their final stand. Following a 50-minute preparation involving air, naval, and artillery support on March 11, Colonel Liversedge’s 28th Marines launched their attack on the left with three battalions in line, while Colonel Wornham’s 27th Marines attacked on the right with four battalions. However, fierce resistance soon forced the combat to close quarters, resulting in the Marines advancing only a few yards—up to 50 yards—across the front.

To the right, while the 21st Marines advanced northward to connect with the 5th Division, Colonel Kenyon’s 9th Marines resumed their assaults on Cushman’s Pocket. The 1st and 3rd Battalions effectively eliminated all resistance in the eastern sector, completely sealing off the area controlled by the Japanese. On March 12, these battalions launched an attack westward toward Cushman’s Pocket, with Colonel Withers’ 3rd Battalion serving as a holding force on the opposite flank. However, the Marines faced strong opposition and could only advance slowly against the camouflaged enemy positions. To the north, Rocky’s units continued to face intense resistance, with Liversedge making no progress and Wornham achieving only minor advances. An intelligence officer with the 5th Division estimated that a minimum of 1,000 Japanese troops were defending the northern end of the island, and stated ". . . there is no shortage of manpower, weapons, or ammunition in the area the Japanese have left to defend." The entire northern tip of the island seemed to be honeycombed with caves and passageways. When a 500-pound bomb landed in the mouth of a cave near Kitano Pint, a big puff of smoke blew out the side of a cliff over 400 yards away, and another bomb landing in a cave entrance in the same area caused a ring of smoke and dust to come up through the ground for a radius of 200 yards around the point of impact.

Meanwhile, to the south, the 25th Marines pressed eastward while Colonel Jordan’s 3rd Battalion contained the pocket from the north. Supported by tanks, flamethrowers, bazookas, anti-tank grenades, and 60mm mortars, Lanigan’s troops engaged in fierce combat with the heavily fortified Japanese forces in the pocket for four days. During this time, Jordan’s 2nd Battalion cleared the beach road, allowing the Shermans to move behind the pocket. On March 13, as Withers’ 3rd Battalion returned to the 21st Marines, Kenyon’s 1st and 3rd Battalions continued their offensive from the east, making significant gains that reduced Cushman’s Pocket to 250 yards. Meanwhile, following a successful water-borne reconnaissance of Kama and Kangoku Rocks the previous afternoon, an armored amphibian company landed on these islets without encountering any resistance. At the same time, Rocky’s weary Marines maintained pressure on the ridge above the gorge, achieving only slight gains on the right. Fortunately, by March 14, it seemed that the slow, arduous progress of the past three days had enabled the 27th Marines to push through the last strong enemy positions along the northeastern side of the island.

As a result, Liversedge was instructed to hold position while the 26th and 27th Marines advanced north and northwest against lighter resistance, successfully gaining up to 1,000 yards by March 15.After armored dozers hacked paths forward, tanks were able to lend support. The flame tanks were particularly effective during this phase and provided "the one weapon that caused the Japanese to leave their caves and rock crevices and run." Army planes flew the last air support missions of the operation on 14 March when five P-51's dropped fire bombs (gasoline and diesel oil mixture) and strafed in front of 3/27 from 1030 to 1100. From then on, the narrow confines of the area of operations prevented use of those planes that had performed so well in supporting ground troops. Artillery and destroyers continued to furnish limited support, firing a preparation for RCT 26 on 15 March and performing night harassing and illumination missions.

Meanwhile, operations against Cushman's Pocket entered their final phase on March 14, when Kenyon’s 1st and 3rd Battalions finally breached the last enemy defenses by nightfall and completed the cleanup of the pocket two days later. On March 15, Lanigan redirected the main focus of the attack on Senda’s pocket to the south, ordering the two battalions in the center to engage aggressively, resulting in a gain of approximately 200 yards and a deep penetration into the left flank of the Japanese's strongest positions. During the night, enemy forces attempted to infiltrate Marine lines from the south, but each attempt was detected and thwarted. Lanigan launched his final assault on March 16, facing only small, isolated pockets of resistance that were quickly eliminated as his battalions advanced toward the beach road. That day, with organized resistance in the 3rd Division's area of operations coming to an end, the 21st Marines were deployed to relieve the 27th Marines on the right flank to continue the northwest attack. With strong naval and artillery support, Withers’ 1st Battalion encountered light resistance in its sector on the right, while the 2nd Battalion faced tougher opposition from scattered enemy positions. Nevertheless, both battalions reached the coastline at Kitano Point by the afternoon and began mopping up. To the left, Colonel Graham’s 26th Marines also advanced cautiously northwest, with tanks effectively neutralizing enemy positions as the Marines gained about 400 yards.

Despite the presence of 500 determined enemy troops still resisting in the western section of Kitano Point and the draw to the southwest, Iwo Jima was officially declared secured by the end of the day. However, on March 17, the battle for the gorge commenced as the 26th Marines advanced under moderate rifle fire, reaching the northern coast before shifting their focus southwestward to confront the gorge in front of the 28th Marines. The gorge in which the last resisting Japanese were now cornered was rocky and steep-sided, approximately 700 yards long and between 200 and 500 yards wide. Rock outcrops cut this ravine into other minor draws that constituted major obstacles to all types of movement. The entire area was ideally suited to the type of last ditch defense the Japanese had adopted. All routes into the main gorge were swept by heavy and accurate fire from machine guns and rifles concealed in cave positions in the cliffs and outcrops. The plan for attacking this strong point called for the 28th Marines, with attached elements of the 5th Pioneer Battalion and Division Reconnaissance Company, to hold the southern rim along the steep cliffs, while the reinforced 26th Marines worked in from the north and east. For the next nine days exhausted Marines carried out a battle of attrition against the thoroughly entrenched enemy. Advances into the east end of the ravine were measured in yards as each cave had to be sealed off before further progress could be made. Flame-thrower tanks, armored bulldozers, and infantry combined operations to provide the power and teamwork necessary to penetrate the last stronghold. As they gradually pushed down the ravine, resistance concentrated around a large concrete structure built into a knoll near the eastern end. After two days of assaults that silenced the supporting positions, engineers used bulldozers to seal a door on the north side and then demolished the structure with five charges totaling 8,500 pounds of explosives. Nevertheless, the battle of attrition persisted, and it wasn't until the end of March 24 that the pocket was reduced to an area of about 50 by 50 yards at the northwest end of the draw. The following morning, units of the 28th Marines, which had taken full responsibility for the pocket, reached the coastal cliffs to finally eliminate the last remnants of resistance in the gorge. On March 20, the 147th Regiment, set to take over the defense of Iwo Jima, arrived from New Caledonia, and by March 24, it had relieved the 21st Marines to establish night ambushes and patrols.

The Japanese defenders fought tenaciously until the very end, choosing death over surrender. However, Kuribayashi had one final assault planned. In the pre-dawn darkness of March 26, the final act of the tragedy was performed. Between 200 and 300 Japanese troops from Death Valley and other scattered positions on the west coast silently crept through the ravines of the 5th Division sector headed for a tented area between Airfield No. 2 and the sea occupied by a mixture of Seabees, Air Force personnel, Shore Parties and AA Gunners. Most of them were sleeping, secure in the knowledge that the battle was virtually over. In a coordinated three-pronged attack against unsuspecting Marines and Air Force ground crews, aiming to create maximum chaos and destruction. Kuribayashi and his men stealthily cut through tents, bayoneted sleeping soldiers, and threw hand grenades, resulting in the deaths of around 44 Airmen and 9 Marines. The noise soon alerted troops from the surrounding area, and Marines from a nearby Pioneer Battalion, african american troops from a Shore Party, and soldiers from the 147th Infantry joined battle in a frenzy of shooting, punching, kicking and stabbing. Once the initial surprise wore off, the defenders retaliated, engaging in a chaotic hand-to-hand combat until the 5th Pioneer Battalion quickly organized a defensive line and halted the attack. Dawn revealed the full extent of the carnage in the ruined encampment: 44 Airman and 9 Marines lay dead with a further 119 wounded; of the attackers 262 were killed and 18 captured. Lt Harry Martin of the 5th Pioneers had hurriedly organized a defense line during the attack and single-handedly killed four enemy machine gunners before dying himself. He was to be Iwo Jima's final Medal of Honor hero, bringing the total to an incredible 27. 

The circumstances of General Kuribayashi's death have always been shrouded in mystery. Over the years various sources have suggested that he died in the fighting around Death Valley or that he killed himself in his HQ. According to General Kuribayashi’s son, Taro: “It seems that it was after sunset on March 25 to the dawn of the 26th that surviving Imperial Japanese forces were obliged to stand still under the US onslaught and showering shells. Under such circumstances, he had his sword in his left hand and ordered the chief staff officer, Colonel Takaishi, who was beside him, 'Send snipers to shoot'. Sargent Oyama heard the order. Oyama, who was seriously wounded in the last combat, fell unconscious, was hospitalized by the US and after having served as a POW came back and testified the dreadful account of the night to me. My father had believed it shameful to have his body discovered by the enemy even after death, so he had previously asked his two soldiers to come along with him, one in front and the other behind, with a shovel in hand. In case of his death he had wanted them to bury his body there and then. It seems that my father and the soldiers were killed by shells, and he was buried at the foot of a tree in Chidori Village, along the beach near Osaka Mountain. Afterwards General Smith spent a whole day looking for his body to pay respect accordingly and to perform a burial, but in vain.”

Following the destruction of this final force, the capture and occupation phase of the Iwo Jima operation was declared complete. Over 34 days of combat, approximately 18,000 Japanese soldiers were killed, and 216 were taken prisoner, while the American side suffered heavy losses: 6,821 killed, 19,217 wounded, and 137 tanks destroyed. On April 4, the 147th Regiment took over full responsibility for the ground defense of Iwo Jima as the Marines were departing the island. Throughout April and May, aggressive patrols and ambushes by infantrymen resulted in an additional 867 prisoners and 1,602 Japanese killed, with the Americans losing 15 killed and 144 wounded. Meanwhile, General LeMay’s 21st Bomber Command continued its firebombing campaign against Japan. After the successful Tokyo Great Air Raid and a less effective attack on Nagoya, LeMay decided to send 301 B-29s on the afternoon of March 13 to strike Osaka.

Despite having to use radar bombing due to cloud cover, American bombardiers achieved a denser and more uniform bombing pattern than the impressionistic methods employed in Nagoya. This resulted in the destruction of 8.1 square miles in the city's core, including commercial and industrial areas, and caused 13,129 civilian casualties, with the loss of 2 bombers and 13 others damaged. Keeping up the intensity of the firebombing campaign, LeMay dispatched 307 B-29s to attack Kobe on the night of March 16. They faced 314 enemy interceptors, which proved ineffective against the Superfortresses unleashing fire over the port. Consequently, the fire on March 17 spiraled out of control, obliterating the eastern half of the business district and devastating a significant industrial zone to the southeast, including the Kawasaki shipyards. Japanese statistics show that the destruction was appalling. About 500 industrial buildings were destroyed, 162 damaged. The loss of 65,951 houses left 242,468 persons homeless. Police reported 2,669 dead or missing and 11,289 injured.

Although the destruction was devastating for the Japanese, LeMay was disheartened to find that only 2.9 square miles of the city had burned. To complete his campaign, LeMay sent 313 bombers back to Nagoya on the night of March 19, utilizing radar techniques to cover a large portion of the city. This resulted in the burning of 3 square miles, including the Nagoya arsenal, freight yards, and Aichi’s engine works. With an average of 380 aircraft, the 21st Bomber Command conducted 1,595 sorties over 10 days, dropping a total of 9,365 tons of bombs. The results far exceeded expectations, as the B-29s left a trail of destruction across four major cities, decimating 32 square miles and destroying numerous critical targets. Thus, LeMay’s strategy proved successful, leading to incendiary area bombing becoming standard practice in the future.

The focus now shifts from the Central Pacific to the South Pacific, where we need to address the ongoing Australian operations in New Britain. Following the capture of Milim and Ea Ea in January, General Ramsay’s 5th Division aimed to continue its limited advances to the north. To secure crossings over the Ip River and patrol towards Henry Reid Bay, the entire 6th Brigade began moving to the Kiep-Milim area on January 26, completing this relocation by February 11. Concurrently, the 14th/32nd Battalion had advanced beyond the Ip and was conducting patrols towards Kalai Plantation, where they faced enemy resistance. The 36th Battalion also moved forward to Mavelo Plantation, leading to retaliatory actions against the new Australian outpost at Baia. In response, Ramsay dispatched stronger patrols to the Sai River throughout February, successfully establishing a new defensive line along the Mavelo River by the month’s end. Returning to Wide Bay, after a series of aggressive patrols and nighttime ambushes, the 14th/32nd Battalion managed to reach Kamandran Mission by mid-February. The Australians continued to advance, and by the end of the month, the 19th Battalion, which had replaced the 14th/32nd at Gogbulu Creek, secured crossings over the Mevelo River and patrolled east toward the Wulwut River. On March 3, Ramsay ordered the 6th Brigade to cross the Wulwut and capture the Waitavalo Ridge. Two days later, the 19th Battalion initiated the assault but struggled to push more than one company across the river due to fierce enemy resistance. On March 6, following an artillery bombardment, another company successfully crossed and quickly seized Cake Hill.

The next day, Lone Tree Hill was taken following another round of artillery bombardment. By March 10, Moose Hill, Young’s Hill, and Perry’s Knoll had also been captured. In the days that followed, Australian artillery began to suppress enemy mortars as infantry moved toward Kath’s Hill. By mid-March, the 14th/32nd Battalion replaced the 19th Battalion, and on March 16, the Australians resumed their offensive, facing fierce resistance but successfully encircling Bacon Hill. The assault continued the next day as the 14th/32nd fought to reach the summit of the hill. On 18th March the mortar fire was intensified from the few remaining enemy positions, and it seemed that the Japanese were firing off their ammunition while they could. The attack was resumed. When Corporal Martin's section was halted on the steep spur by fire from three posts he jumped up shouting, "They can't do that to me", and went on alone, firing posts, killing five, before he himself was hit. The decisive attack was launched through this foothold. By 3 p.m. all the Japanese had been cleared from Bacon Hill; and a patrol from Kath's, under Lieutenant Lamshed,3 penetrated to a knoll 800 yards to the east and found no enemy there. No Japanese now remained in the Waitavalo-Tol area. In the five days from the 16th to the 20th 4 officers and 53 others had been killed or wounded. 

In the following days, patrols ventured deep into enemy territory but found few stragglers. On March 21, the 19th Battalion took over again and advanced toward the Bulus and Moondei Rivers. On March 28, Ramsay ordered the 13th Brigade to relieve the 6th Brigade, a transition that was completed by April 12. Following the capture of Waitavalo Ridge, there were four months of infantry patrolling and routine maintenance by other troops, with the 16th Battalion patrolling forward to Jammer Bay in this area. Additionally, looking west, a company from the 36th Battalion successfully landed north of the Sai on March 30 but could not proceed to the Matalaili River due to heavy rains. However, Japanese positions there were heavily bombarded by aircraft and the sloop Swan, prompting the defenders to withdraw to the Toriu River in April. Meanwhile, Brigadier King’s 16th Brigade advanced to the Ninahau River by March 12, while Brigadier Moten’s 17th Brigade continued its westward push through the Torricelli Mountains, aiming to capture the Japanese base at Maprik.

Throughout March, the 2/7th Battalion executed several successful ambushes from their new bases at Ilahop, Balangabadabil, and Bombeta, while Hayforce advanced through Sinahau to the north of Utumugu and eastward to Tatimba. By early March, Moten had cleverly led the enemy to believe that the primary offensive would be launched by the 2/10th Commando Squadron from the north via Ami. As a result, the Japanese bolstered their forces in that area, successfully driving back Australian patrols from Chaulak, Gwanginan, and Wambak. On March 13, the commando outpost at Milak came under attack, with the Japanese gradually encircling the position in the following days but failing to overcome the defenders’ steadfast resistance. Fortunately, by March 17, patrols had restored communication lines, and two days later, the enemy pressure finally subsided. During this time, smaller Japanese forces also targeted the commando outposts at Murak and Aupik, but the defenders managed to repel these attacks as well. However, as the 2/10th was completely exhausted, the 2/6th Battalion was dispatched to relieve the commandos in late March amid a new wave of Japanese assaults. Meanwhile, the 2/7th Battalion was engaged in assaults on the fortified enemy positions at Ilaheta, which fell on March 20. The Australians then turned their attention to the Aupik villages, successfully focusing their efforts on the west bank of the Ninab River by the end of March, coinciding with Hayforce's crossing of the Amuk River. In the following three days, the 2/7th Battalion cleared all opposition along the eastern side of the Ninab in preparation for the final push toward Maprik. Consequently, General Miyake’s 78th Regiment was ultimately compelled to retreat toward Jamei.

Looking further north, King decided to initiate his advance towards But. By mid-March, a company from the 2/2nd Battalion had crossed the Ninahau on March 14 and quickly moved through Bai and Ultan. Although the Australian advance faced a strong enemy position that delayed progress for two days, the 2/2nd ultimately broke through Manib Creek, catching the defenders off guard and swiftly capturing the But airfield on March 17. Following this, the Australians patrolled the foothills and the Old German Road towards the Dagua airfield, encountering minimal resistance. Consequently, on March 21, the 2/2nd advanced rapidly again, successfully taking Dagua while the 2/1st Battalion moved in to secure But. At this stage, Japanese resistance along the coast was light, as General Adachi had focused on the Maprik district, which could produce more food. With the main enemy forces now concentrated in the hills to the south, King directed the 2/2nd to clear the foothills south of Dagua and eliminate the enemy in the Tokoku Pass, while the 2/3rd Battalion launched a flanking attack in the Mabam River-Hamsuk-Yalaminuni area. The 2/2nd then patrolled deep towards Magahen and Wonginara Mission, facing strong resistance at the 1410 Feature. On March 24, they finally captured the feature, while another patrol reached Wonginara without encountering enemy forces. However, in the final days of March, the Australians struggled to advance against the strong resistance of the Japanese defenders on the Wonginara Track, although one patrol successfully probed towards Kauremerak Hill.

On April 2, following intense air and artillery bombardments, the 2/2nd Battalion finally managed to break through to Tokoku Pass, which was secured the next day. Meanwhile, another patrol advanced south from Dagua to the Autogi-Walanduum area and then to the coast near Kofi. The 2/3rd Battalion moved south from Feature 1410 towards the Mabam River and Wonginara Mission, successfully eliminating a series of Japanese ridge positions by April 6. The 2/1st Battalion patrolled deep into the hills south and west of But, completely clearing the area by April 1 while also pushing eastward to capture Saburuman. Concurrently, the 2/3rd Machine-Gun Battalion advanced to the upper Ninahau, effectively clearing the region up to a north-south line about two miles beyond Muguluwela by the end of March. In early April, the machine-gunners successfully cleared the Marabus area and connected with the 2/1st Battalion. Finally, it was time to shift focus to Bougainville to continue covering the Australian offensives on the island. As previously noted, Brigadier Stevenson’s 11th Brigade had secured the Tsimba Ridge area, while Brigadier Field’s 7th Brigade was advancing south towards the Puriata River. The swift capture of Mosigetta and the unexpected secondary landing at Toko had already compelled the Japanese to retreat behind the river amid a command crisis.

The Japanese policy of resisting the southward advance more strongly even if it entailed heavier casualties failed to impose the hoped-for delay of the Australians. Nevertheless the Japanese leaders considered that the 13th Regiment's "swift damaging hit-and-run tactics" were well executed. However, Mosigetta was at length abandoned and a withdrawal south of the Puriata ordered. The landing at Toko was unexpected and caused an acceleration of this withdrawal. There now occurred a major crisis in the Japanese command. The young reserve officers were highly critical of the conduct of the campaign and blamed the policies of the older professional officers for the constant reverses. This criticism became so outspoken that, in February, a number of the younger officers were relieved of their commands; perhaps partly as an outcome of this crisis, General Hyakutake suffered a paralysis of his left side. General Kanda took command of the 17th Army and Lieutenant-General Akinaga Tsutomu, Chief of Staff of the Army, succeeded him in command of the 6th Division. "This change of command was regarded favourably by the younger officers, but it soon became apparent that Kanda intended to pursue the same policy as Hyakutake. Kanda was a shrewd, hard, fussy little professional soldier of long experience. He was steeped in tradition and a ruthless commander, but even his bitterest critics admitted his capabilities. Akinaga… was a dyed in the wool militarist and a strict disciplinarian. Unused to an active command he was plunged into a situation which was a little out of his depth. One of his staff stated that he spent too much time doing a corporal's job in his forward battalions to be a good divisional commander."

In late February, General Bridgeford’s forces advanced toward the Puriata, facing only minor rearguard positions. The 25th Battalion captured Barara on February 22 and a five-acre garden two days later, while the 61st Battalion took control of another garden measuring 600 by 400 yards near the river on March 1. Meanwhile, the 2/8th Commando Squadron was sent to secure the Makapeka area, successfully taking Commando Ridge and a ford across the Makapeka River by March 5. With General Savige aiming to reach the Hari River next, Bridgeford promptly ordered the 7th Brigade to move to the Hongorai River line. As a result, Field planned to initiate his main advance on March 11, utilizing the 25th Battalion and the 2/8th Commando Squadron, while the 61st Battalion pushed forward toward Horinu. In response, Kanda dispatched the 23rd Regiment to bolster the 13th at the front, preparing both units for a full-scale counterattack should the Australians cross the Puriata, aiming to delay the enemy long enough to finalize preparations for a decisive battle along the Silibai-Porror Rivers. By March 5, the 25th Battalion had already crossed the river and swiftly captured Slater’s Knoll, which soon came under enemy mortar fire. Patrols were sent ahead and found that the 13th Regiment was poised to fiercely contest the Australian advance. Although the northern flank of the 25th Battalion would be effectively contained along the Buin Road on March 11, two Australian companies managed to maneuver through Tokinotu to the south, reaching Hiru Hiru by the end of the day.

One of these companies moved along the eastern side of the Buin Road toward Slater's Knoll, but from March 15 to 17, they faced a heavy counterattack that ultimately forced them to withdraw. In response, Field initiated a strong offensive along the Buin Road on March 19, managing to push the Japanese back to some rear positions. Following a significant air and artillery bombardment, the attack resumed on March 22, successfully overcoming all enemy resistance. Meanwhile, the commandos advanced to Nihero, where they began extensive patrols southward towards Unanai, Hari, and the Buin Road. During one of these patrols, they captured detailed orders for a large-scale Japanese offensive planned for early April. As a result, Bridegeford decided to pause his offensive and send the 15th Brigade along with a tank squadron to Toko to reinforce his perimeter. On March 28 and 29, before Akinaga's main assault, the Japanese conducted a series of raids on the Australian lines of communication and rear areas, all of which were successfully repelled by vigilant defenders. On March 30, the 13th Regiment launched several strong attacks against the 25th Battalion, all of which were costly for the attackers and repelled, while the armored squadron advanced toward Tokinotu. Just as the tanks reached the front, the Japanese initiated another wave of fierce attacks against the 25th Battalion on March 31, which were thankfully repelled with the support of the armored units. Consequently, on April 1, two companies advanced again, establishing a perimeter 1,000 yards south of Slater's Knoll. That evening, and for the following three days, Akinaga launched a series of raids to facilitate the arrival of the 23rd Regiment for a renewed assault.

In the early hours of April 5, the Japanese began infiltrating the Australian perimeter, launching a vigorous two-pronged assault on Slater’s Knoll later that morning. The 23rd Regiment attacked about 1,000 yards to the right of the 13th and north-east of it. The attack failed, Kawano was killed and the regiment withdrew south to the rear of the 13th. The 13th Regiment with 600 men made the main attack from north and east. 

Until 6.20 a.m. wave after wave charged forward and was brought low. Some Japanese fell within four yards of the weapon-pits. The artillery sent over accurate defensive fire, registered the previous day. At dawn the surviving Japanese were heard digging in on dead ground. As the light became clearer, the Australians saw that "enemy dead lay, literally, in heaps in front of the wire", and bodies could be seen scattered over an area some 200 yards square. It was gruesome evidence of the efficient siting of weapons and choice of fields of fire in preparation for expected attack. The attackers were ordered to dig in until darkness and make full use of grenades and mortars. However, in the afternoon, tanks and artillery fire drove the Japanese from the positions they had gained, and the Japanese commander accepted defeat. All three battalion commanders in the 13th were killed. After Akinaga had reported his failure Kanda said to his Chief of Staff, Colonel Yoshiyuki Ejima: "It would not have happened if I had been in command. The enemy right flank was wide open. I would have severed his life line and controlled Toko. We could have delayed the enemy for three months." 

Concurrently, around 100 Japanese troops attacked the two forward companies along the Buin Road but were similarly repelled with ease. Following the unsuccessful counteroffensive by Akinaga, Slater’s Knoll received reinforcements while the remaining Japanese forces were being dealt with, resulting in 620 Japanese fatalities since March 28, compared to 189 Australian casualties. However, Bridgeford could not capitalize on this victory due to the prolonged supply line, which temporarily halted his offensive. As a result, while the 2/8th Commando Squadron moved forward along the Commando Road, the 13th Brigade began to relieve the battered 7th Brigade under Field on April 13. Meanwhile, in the northern sector of the 11th Brigade area, the 26th Battalion launched a significant advance northward on February 21, successfully overrunning the Lalum-Downs’ Ridge area by March 8. Two companies then advanced further north to secure the crossing of the Nagam River. On March 13, another company landed near the southern edge of Soraken Plantation and quickly pushed the enemy back behind the Nagam. Australian patrols harassed the Japanese forces at Horseshoe Knoll until March 20, when they finally withdrew. Simultaneously, the 26th Battalion eliminated the remaining enemy positions at the Compton River and secured the Soraken Peninsula, while the Taiof and Saposa Islands were also captured off the coast.

The next battalion to take over the forward positions was the 31st/51st Battalion. Perhaps the outstanding patrol leader in the 31st/51st was Lieutenant Reiter, who led out 3 patrols which killed 10 out of the 78 Japanese killed by this battalion's forays. One of these patrols was named by the battalion "the raid on Reiter's Ridge". Reiter and 15 men were given the task of harassing the Japanese occupying a prominent ridge just east of Sisivie and discovering their strength. They departed from Keenan's Ridge at 17:30 on March 27, bivouacked at a former artillery observation post and moved on at 03:00 next morning for a dawn attack. At 06:00 “the patrol moved in, and throwing grenades and firing LMG occupied a small knoll (its report stated). 2 Japanese were killed and 1 pillbox containing LMG destroyed. Patrol raced down narrow neck to a wide clearing in which several huts were sighted. Phosphorus and HE grenades were thrown. In a matter of seconds 4 more Japanese killed (2 in slit trenches, 1 as he ran and another while abluting). 2 were wounded by phosphorus grenades. 3 huts were blazing and 1 (considered to be an ammunition dump) blew up. Enemy opened up with one LMG and 15 rifles and patrol pulled out with 1 man wounded.” Instead of hastening them away Reiter assembled his men nearby in concealment and watched the enemy. At length Japanese began to move about again, and soon they were washing clothes, chopping wood and performing other tasks. There were from 25 to 30 enemy in the post. The Australians watched throughout the morning and at 12:30 opened fire with all their weapons. 2 Japanese were killed and 4 more huts set on fire. The enemy fired back, and at 01:15 Reiter withdrew his men and returned to Keenan's Ridge leaving an ambush on the enemy's track. The ambush party returned later and reported that it had seen no movement. 

On the 29th, the day after Reiter's return, a platoon of the 1st New Guinea Infantry Battalion under Lieutenant Martin set out for Buritsiotorara along the Wakunai River. There they found three huts and a large garden with seven Japanese moving about unarmed. Throwing grenades and firing from the hip the native soldiers attacked and killed all seven. Three more who emerged from a hut were chased and killed. Three of the dead men were found to be lieutenants; three machine-guns were cap-tured. Next day at Aviang, 1,200 yards away, seven more Japanese were seen, of whom three including another lieutenant were killed and the others fled.

The battle for Iwo Jima had come to a bitter end. The lessons learnt on Iwo Jima would become guidelines for the Battle of Okinawa in April and would influence allied plans for the invasion of the Japanese home islands. The war planners would later notably take into account that around a third of the troops committed to Iwo Jima, and later again at Okinawa, had been killed or wounded and that they could expect far more in Japan.

- 173 - Pacific War Podcast - Fall of Mandalay - March 11 - 18 - , 1945

Last time we spoke about the Great Tokyo Air Raid. Amidst fierce battles, Liversedge's forces captured key hills but faced relentless Japanese machine-gun fire. Despite heavy casualties, the Marines advanced, securing strategic positions. General Kuribayashi recognized their struggle, while the Japanese counterattacks faltered. After 19 grueling days, the last pockets of resistance fell, marking a costly victory for the Americans. Amid the fierce battle of Iwo Jima, General LeMay shifted tactics, launching incendiary raids on Tokyo. On March 9, 1945, 334 B-29s unleashed destruction, igniting widespread fires and devastating neighborhoods. The attack shattered Japanese morale, while LeMay's strategy proved effective, paving the way for further offensives in the Pacific. On March 3, three brigades attacked Meiktila, facing fierce resistance. Tanks overwhelmed Japanese forces, resulting in heavy casualties. As Cowan fortified defenses, Japanese counterattacks intensified. Meanwhile, in Mandalay, British-Indian troops advanced, capturing key positions. Amidst confusion and conflicting orders, the Allies pressed forward, striving for victory in Burma.

We are first picking up this week with the men fighting over northern Luzon. By March 5, General Clarkson’s 33rd Division had advanced to Agoo and Pago while gradually pushing the enemy along Route 11. Meanwhile, Colonel Volckmann’s guerrilla force was carrying out limited offensives in the Laoag, Cervantes, and San Fernando regions. Coming into Salacsac Pass from the west, the Villa Verde Trail twists up the wooded western slopes of a steep-sided height known to the 32nd Division as Hill 502. Another peak, bare crested, forming part of the same hill mass and named Hill 503, centers 250 yards northeast of the crest of Hill 502, while a similar distance to the southeast is Hill 504. Winding along the southern slopes of Hills 502 and 504, the trail continues eastward through a low saddle about 500 yards long, climbing again up the forested northwestern side of Hill 505. After crossing that hill, the trail follows a twisting course 600 yards--as the crow flies--eastward, hugging the densely wooded northern slopes of Hills 506A and 506B. Off the northeast corner of Hill 506B the trail turns south for 1000 yards--again a straight-line distance--and traverses the east side of the noses of Hill 507, designated from north to south A, B, C and D. Turning sharply east again near Hill 507D, the trail continues east another 700 yards and then enters a deep wooded saddle between Hill 508 on the south and Hill 515 to the north. After passing through this saddle, which is about 250 yards long east to west, the trail goes on eastward, dominated on the north by Hills 516 and 525. Roughly 1250 yards beyond the saddle the trail twists across the northern slopes of Hill 526, which lying about 500 yards southeast of Hill 525, marks the eastern limits of the Salacsac Pass area. A mile and a quarter of less rugged but still forested and difficult terrain lies between Hill 526 and barrio Imugan, in turn two and a quarter miles west of Santa Fe. 

Meanwhile General Mullins’ 25th Division had successfully taken control of Puncan and Digdig. Due to this unexpectedly swift progress, General Swift instructed Mullins to continue advancing toward Putlan while the 1st Battalion, 127th Regiment fought for control of Hill 502, which was secured on March 7. In response, Mullins dispatched the 161st Regiment to attack the high ground west of Route 5, the 27th Regiment to advance along and east of the highway, and the 35th Regiment to execute a wide envelopment to the east. Since this last flank approach to Putlan was completely undefended, the 1st Battalion, 35th Regiment quickly occupied Putlan on March 8. The following day, the 27th Regiment also arrived in the area and began clearing Japanese stragglers from the ravines east of Route 5 near the barrio, a task that would not be finished until March 15. Finally, despite facing rough terrain and light resistance, the 161st Regiment reached Putlan on March 10, successfully securing the high ground to the west. To the north, as the 1st Battalion, 127th Regiment struggled to make significant progress eastward after capturing Hill 502, Gill decided to send the 3rd Battalion, 127th Regiment to outflank the Salacsac Pass defenses from the south. 

Although the extremely rough, precipitous mountain country of the Salacsac Pass area, averaging 4500 feet above sea level, was covered by dense rainforest, from Hill 506B to Hill 526, there was sufficient open ground throughout to provide the defender with excellent observation. It was not too difficult for the Japanese to find positions whence they could cover with fire every square foot of the Villa Verde Trail through the pass area. The twisting of the trail also provided defense opportunities, for in a given 1000 yards of straight-line distance through the pass, the trail might actually cover a ground distance of 3000 yards. Whatever its shortcomings in other fields, the Japanese Army always had a feel for terrain, exploiting to the full every advantage the ground offered. Thus, as it moved up, the 2nd Tank Division set to work to establish a system of mutually supporting defensive positions in order to control every twist of the Villa Verde Trail and every fold in the ground throughout the pass area. Every knoll and hillock on or near the trail was the site of at least one machine gun emplacement; every wooded draw providing a route for outflanking a position was zeroed in for artillery or mortars. The cave, natural or man-made, came to characterize the defenses. Artillery was employed in quantity and quality not often encountered in engagements against the Japanese, who, as usual, made excellent use of their light and medium mortars. Finally, the 2nd Tank Division was overstocked in automatic weapons, evidently having available many more than the 32nd Division could bring to bear.

To the west, following recent successes in patrols, Clarkson opted to establish a new "secure line" stretching from Aringay southeast through Pugo to Route 11 at Twin Peaks. Consequently, patrols quickly secured Aringay and Caba without facing any opposition, then advanced east along the trails to Pugo and Galiano, and north to Bauang, where they continued to encounter minimal enemy presence. As a result of these movements, the Hayashi Detachment was ultimately withdrawn to bolster the main defenses at Sablan, enabling Volckman’s 121st Regiment to enter San Fernando on March 14. Additionally, elements of the 19th Division began arriving in the Cervantes area from Baguio and successfully expelled the guerrilla company from the town in early March. The Filipinos recaptured Cervantes on March 13 but soon found themselves targeted by Japanese artillery positioned on elevated ground. Meanwhile, looking south, by March 5, General Patrick’s 6th Division had commenced unsuccessful assaults on Mounts Pacawagan and Mataba, while General Hoffman’s 2nd Cavalry Brigade struggled to advance toward the Antipolo area. Recognizing that the success of his attack required a concentration of forces along a narrower front, General Griswold decided to focus on the Noguchi Force and the left flank of the Kobayashi Force, as the northern area was heavily fortified. He retained only one battalion as an infantry reserve and directed the remainder of his available forces, all of which were understrength, to push eastward. Alongside the deployment of the 1st Cavalry Brigade, the 103rd Regiment reached Taytay on March 7 to serve as the 1st Cavalry Division Reserve, signaling the upcoming relief of the cavalrymen in preparation for their redeployment to southern Luzon.

By March 10, General Wing’s 43rd Division had been replaced in the Clark Field area by the 38th Division and was en route to the eastern front.  The 38th Division pushed on into the untracked, ill-explored, and worse-mapped wilderness of the central Zambales Range, its progress slowed more by supply problems than Japanese resistance. In early April the division noted that the last vestiges of any controlled defensive effort had disappeared. Unknown to 11th Corps General Tsukada, on April 6, had given up and had ordered his remaining forces to disperse and continue operations, if possible, as guerrillas. For the Japanese remnants, it was a case of sauve qui peut. Some tried to escape to Luzon's west coast, whence 38th Division troops were already patrolling inland; others tried to make their way north through the mountains, only to be cut down by American patrols working southward from Camp O'Donnell. The 38th Division had killed about 8000 of the scattering Japanese by the time it was relieved by units of the 6th Division on May 3. The losses of the 38th totaled approximately 100 men killed and 500 wounded. The 6th Division, elements of which remained in the Kembu area until June 25, limited its operations to patrolling and setting up trail blocks along Japanese routes of escape. Troops of the 38th Division ultimately returned to the region and remained there until the end of the war. Insofar as US forces were concerned, the mop-up period under 11th Corps control was even more costly than had been the 14th Corps' offensive period. From February 21 to the end of June the various elements of 11th Corps committed to action against the Kembu Group lost approximately 550 men killed and 2200 wounded. The Kembu Group, during the same period, lost 12500 killed or dead from starvation and disease. By the end of the war the original 30000 troops of the Kembu Group were reduced to approximately 1500 sorry survivors, about 1000 of them Army personnel. Another 500 had already been taken prisoner.

As a result, General Tsukada ordered his remaining troops to scatter and operate as guerrillas. Meanwhile, Griswold resumed his eastern offensive on March 8. In the south, bolstered by artillery and mortars, the battered 2nd Cavalry Brigade continued to advance slowly under heavy artillery fire, reaching a point 440 yards short of Antipolo along Route 60A and overcoming the enemy cave defenses at Benchmark 11. By March 11, patrols had entered Antipolo, discovering the town was devastated and deserted, yet still under the threat of Japanese artillery and mortars positioned in the hills to the north and northeast. Simultaneously, the 1st Cavalry Brigade made significant strides to the north, also coming within 440 yards of Antipolo while clearing Benchmark 9 Hill and Hills 520 and 740. Abandoning the Montalban-San Mateo area, Patrick instructed the 1st and 20th Regiments to advance toward Mounts Baytangan and Yabang. Facing unexpectedly light resistance, the 1st Regiment advanced a mile and a half east by March 11 and secured Benchmark 8 Hill to the south despite encountering stubborn opposition. Recognizing the need to capitalize on this success, Patrick then ordered the 20th Regiment to move through the 1st and attack north toward Wawa Dam while the latter continued its eastward assault.

On March 11, the 103rd Regiment took over from the 2nd Cavalry Brigade and quickly began planning to outflank General Noguchi’s defenses located southeast of Antipolo. However, due to concerns over American advances, General Yokoyama ordered the Noguchi Force to retreat to secondary defensive positions while preparing for a three-pronged counterattack set for March 12. The primary effort involved four reserve battalions from the Kobayashi Force, which launched an attack southward from Mount Mataba toward Marikina but were quickly halted by intense air and artillery fire, falling far short of their target. Additionally, the 182nd Independent Battalion attempted a counterattack toward Benchmark 8 but was unsuccessful, while the majority of the Kawashima Force advanced south from the Ipo Dam area to assault the rear installations of the 6th Division west of the Marikina River, where they were easily repelled by March 15.

During this so-called counterattack, Griswold continued his offensive, with the 103rd Regiment swiftly advancing through the deserted Antipolo to Benchmark 7 Hill, and the 20th Regiment moving over a mile north to secure a position on a grassy ridge less than a mile southeast of Mount Mataba's summit. On March 14, the 1st Regiment resumed its eastern assault, successfully advancing north to a bare peak about a mile southwest of Mount Baytangan, despite facing strong resistance that caused heavy casualties, including the loss of General Patrick, who was succeeded by Brigadier-General Charles Hurdis as commander of the 6th Division. Simultaneously, Wing initiated a coordinated offensive with two regiments toward Mounts Yabang, Caymayuman, and Tanauan, aiming to flank the Shimbu Group's left. Although the 103rd and 179th Regiments achieved significant progress that day, Noguchi’s determined defenders managed to maintain control of Benchmark 7.

Looking further south, Griswold was preparing to launch a two-pronged offensive in southern Luzon. General Swing’s 511th Parachute Regiment and the 187th Glider Regiment were set to advance towards Lipa from the north and northwest, while the 158th Regiment gathered near Nasugbu to attack southeast along Route 17 toward Balayan Bay. In response, Colonel Fujishige’s Fuji Force had established several small positions in the area to prevent American forces from flanking the Shimbu Group's main defenses by rounding the eastern shore of Laguna de Bay. Swing’s offensive commenced on March 7, with the 187th Glider Regiment descending the steep southern slopes of Tagaytay Ridge to the northern shore of Lake Taal, ultimately stopping at a hill two miles west of Tanauan due to strong resistance. The 511th Parachute Regiment moved out from Real, reaching within a mile of Santo Tomas while launching unsuccessful frontal assaults on Mount Bijiang. Meanwhile, the 158th Regiment advanced from Nasugbu, quickly securing Balayan before pushing eastward with little opposition toward Batangas, which fell on March 11. On its eastward path, the regiment bypassed significant elements of the 2nd Surface Raiding Base Force on the Calumpan Peninsula, necessitating that a battalion clear that area by March 16. At the same time, other units of the 158th Regiment encountered robust Japanese defenses blocking Route 417 at Mount Macolod, where their advance came to a halt. Concurrently, General Eichelberger continued his offensive against the central islands of the Visayan Passages, with reinforced companies from the 1st Battalion, 19th Regiment successfully landing on Romblon and Simara islands on March 11 and 12, respectively.

Most importantly for Eichelberger, he was about to initiate his Visayas Campaign. To disrupt Japanese communication lines across the South China Sea, the 8th Army needed to quickly capture airfields that would allow the Allied Air Forces to project land-based air power over the waters west of the Philippines more effectively than from Clark Field or Mindoro. Consequently, the first target chosen was Palawan, which was defended by only two reinforced companies from the 102nd Division. Additionally, MacArthur's strategy included the eventual reoccupation of the East Indies, starting with the capture of Japanese-controlled oil resources in northern Borneo as soon as land-based air support was available. The Zamboanga Peninsula and the Sulu Archipelago were identified as the second targets, although these areas were defended by stronger garrisons from the 54th and 55th Independent Mixed Brigades. Despite this, Eichelberger tasked Major-General Jens Doe’s 41st Division with executing these invasions. For the Palawan invasion, codenamed Operation Victor III, Brigadier-General Harold Haney was appointed to lead a force primarily composed of the 186th Regiment, which would be transported to the island by Admiral Fechteler’s Task Group 78.2. The convoy departed from Mindoro on February 26, escorted by Rear-Admiral Ralph Riggs’ cruisers and destroyers. Following a naval bombardment, Haney’s Palawan Force successfully landed at Puerto Princesa on February 28 without encountering any opposition. They quickly secured the town and the two airstrips to the east, advancing to the western and southern shores of the harbor by late afternoon to establish a defensive perimeter.

As the first day progressed, it became clear to the American troops that the Japanese troops would not put up a fight at Puerto Princesa and had withdrawn into the hills to the northwest. More disturbing was the revelation of a massacre of approximately 140 American prisoners of war the previous December. The presence of a passing Allied convoy made the alarmed Japanese believe that an invasion was imminent and had herded their prisoners into air-raid shelters, subsequently setting the shelters afire and shooting prisoners who tried to escape. Only 11 American prisoners of war miraculously survived immolation and escaped the shooting. Sheltered by natives until the Americans landed, they emerged during the battle to tell their horrifying tale, which only hardened American resolve to end Japanese rule over the island.

By March 1, the 186th Regiment had successfully taken control of Irahuan and Tagburos. In the following week, American forces would eliminate two or three heavily defended strongholds located ten miles north-northwest of Puerto Princesa, where the enemy garrison was ultimately defeated. The Palawan Force also conducted reconnaissance of several offshore islets, discovering no Japanese presence on some and swiftly clearing others. However, due to the poorly compacted soil, the new airfield on the island would not be operational until March 20, which was too late for any aircraft based in Palawan to assist with the Zamboanga landings. Consequently, on March 8, two reinforced companies from the 21st Regiment were flown to the airstrip at Dipolog, which had been secured by Colonel Hipolito Garma’s guerrilla 105th Division. On the same day, sixteen Marine Corsairs arrived to provide air support for the invasion of Zamboanga, codenamed Operation Victor IV. For this operation, Doe assigned the remainder of his division, which was to be transported by Rear-Admiral Forrest Royal’s Task Group 78.1. After three days of pre-assault bombardments and minesweeping, the convoy finally set sail southward and entered Basilan Strait from the west early on March 10. Troops from the 162nd Regiment landed almost without opposition around 09:15 near barrio San Mateo and quickly secured Wolfe Field, while the 163rd Regiment was also landing. Doe’s two regiments then began to advance inland, facing minimal resistance as they established a night perimeter. With the Japanese having withdrawn, the 162nd and 163rd Regiments easily secured Zamboanga City, San Roque Airfield, and the rest of the coastal plain by dusk on March 11, with one company extending further to Caldera Bay to the west.

To drive the Japanese forces from the elevated positions overlooking the airfield, Doe dispatched the 162nd Regiment towards Mount Capisan and the 163rd Regiment towards Mount Pulungbata. Additionally, the guerrilla 121st Regiment was tasked with blocking the east coast road in the Belong area. Supported by continuous artillery fire and close air support from Marine Corps planes, the two regiments of the 41st Division faced arduous tasks. General Hojo's troops held excellent defenses in depth across a front 5 miles wide, some portions of the line being 3 miles deep. All installations were protected by barbed wire; abandoned ground was thoroughly booby-trapped; mine fields, some of them of the remote-control type, abounded; and at least initially the 54th Independent Mixed Brigade had an ample supply of automatic weapons and mortars. While Japanese morale on the Zamboanga Peninsula was not on a par with that of 14th Area Army troops on Luzon, most of the 54th Independent Mixed Brigade and attached units had sufficient spirit to put up a strong fight as long as they held prepared positions, and Hojo was able to find men to conduct harassing counterattacks night after night. Finally, the terrain through which the 41st Division had to attack was rough and overgrown, giving way on the north to the rain forests of the partially unexplored mountain range forming the backbone of the Zamboanga Peninsula. Only poor trails existed in most of the area held by the Japanese, and the 41st Division had to limit its advance to the pace of bulldozers, which laboriously constructed supply and evacuation roads. Once the American troops entered the peninsula's foothills, tanks could not operate off the bulldozed roads. The next day, the 186th Regiment was deployed to relieve the fatigued 163rd Regiment on the eastern front. By the end of the month, it had expanded the front eastward and northward against diminishing resistance, ultimately forcing Hojo’s forces to retreat into the rugged interior of the peninsula.

For now, however, we will shift our focus from the Philippines to Burma to continue our coverage of the Chinese-British-Indian offensives. As we last observed, General Stopford’s 33rd Corps was aggressively advancing into Mandalay against a weakened 15th Army, while General Cowan’s 17th Indian Division had successfully captured Meiktila and was preparing to withstand the combined assaults of the 18th and 49th Divisions. Cowan's forces conducted a robust defense, managing to delay the arrival of the 49th Division until March 18 and successfully repelling General Naka’s initial attacks on Meiktila’s main airfield. Furthermore, with the reserve 5th Indian Division moving closer to the front in preparation for an advance towards Rangoon, General Slim decided to airlift the 9th Brigade to reinforce Cowan’s troops, which landed on Meiktila’s main airfield under enemy fire between March 15 and 17.

Due to the slow progress on this front and General Katamura's preoccupation with the battles along the Irrawaddy, he was unable to manage the southern units simultaneously. Consequently, General Kimura decided to assign the 33rd Army to take over the fighting in Meiktila. General Honda promptly moved to Hlaingdet, where he was tasked with overseeing the 18th, 49th, and 53rd Divisions. On March 18, he ordered the 18th Division to secure the northern line of Meiktila and neutralize enemy airfields. He instructed the 49th Division to advance along the Pyawbwe-Meiktila road and directed the 53rd Division to regroup near Pyawbwe. However, on that same day, Cowan launched a counterattack by sending two tank-infantry columns to disrupt Japanese preparations along the Mahlaing road and in the villages of Kandaingbauk and Shawbyugan. They faced heavy resistance at Shawbyugan and ultimately had to withdraw. The relentless air assaults also compelled the Japanese to operate primarily at night, limiting their ability to respond with similar force to British offensives. On the night of March 20, Naka decided to initiate a significant attack on Meiktila’s main airfield. However, with the 119th Regiment delayed at Shawbyugan, the 55th Regiment had to proceed alone, supported by some tanks, against the defenses of the 99th Brigade around Kyigon. Heavy artillery and mortar fire ultimately disrupted their assault. Meanwhile, as the 49th Division was consolidating its forces to the southeast, Cowan opted to send two tank-infantry columns to eliminate enemy concentrations at Nyaungbintha and Kinlu. Although the initial sweeps met little resistance, the 48th Brigade encountered strong Japanese positions at Shwepadaing on March 21.

The next day, Cowan dispatched two tank-infantry columns to secure the Shwepadaing and Tamongan regions, but the British-Indian forces still struggled to eliminate the enemy defenders. That night, Lieutenant-General Takehara Saburo initiated his first significant assault, with the majority of the 106th Regiment targeting the defensive positions of the 48th Brigade in southeastern Meiktila. Despite the fierce and relentless attacks from the Japanese throughout the night, they were ultimately repelled by artillery and machine-gun fire, suffering heavy casualties. On March 23, Cowan sent another tank-infantry column to chase the retreating Japanese forces; however, the reformed 169th Regiment at Kinde successfully defended against this advance. Meanwhile, on the night of March 24, Naka launched another major offensive with the 55th and 119th Regiments, managing to capture Meiktila’s main airfield. In response, Cowan quickly dispatched a tank-infantry column to clear the Mandalay road, successfully securing the area northeast of Kyigon by March 26. At this time, Honda had relocated his headquarters to Thazi to better coordinate the battle, although his troops had already suffered significant losses. For the next three days, Cowan’s tanks and infantry continued to advance along the Mandalay road while the 63rd and 99th Brigades worked to eliminate Naka’s artillery units south of Myindawgan Lake. By mid-March, Stopford’s relentless pressure had forced the 31st and 33rd Divisions to retreat in chaos. On March 20, organized resistance in Mandalay was finally shattered as the 2nd British Division linked up with the 19th Indian Division. Consequently, the beleaguered Japanese units had no option but to withdraw in disarray towards the Shan Hills to the east.

Following the collapse of the 15th Army front, the 33rd Army received orders on March 28 to hold its current positions only long enough to facilitate the withdrawal of the 15th Army. Consequently, while Cowan’s units cleared the region north of Meiktila, Honda halted all offensive actions and promptly directed the 18th Division to secure the Thazi-Hlaingdet area. Additionally, the weakened 214th Regiment was tasked with moving to Yozon to support the withdrawal of the 33rd Division, while the 49th and 53rd Divisions were assigned to contain Meiktila to the south. As the battles for Mandalay and Meiktila unfolded, the reinforced 7th Indian Division at Nyaungu faced several intense assaults from General Yamamoto’s 72nd Independent Mixed Brigade throughout March, ultimately advancing to Taungtha and clearing the route to Meiktila by the month's end. Meanwhile, in northern Burma, the 36th British Division advanced toward Mogok, which fell on March 19, while the 50th Chinese Division approached the Hsipaw area. Interestingly, the Japanese abandoned Hsipaw without resistance but launched a fierce counterattack between March 17 and 20. Ultimately, General Matsuyama had no option but to prepare for a withdrawal south toward Lawksawk and Laihka. At this stage, the 38th Chinese Division resumed its advance to Hsipaw; however, facing strong opposition along the route, they did not arrive until March 24, when the entire Burma Road was finally secured. General Sultan believed this was his final maneuver and recommended relocating the Chinese forces back to the Myitkyina area for air transport back to China, except for those needed to secure the Lashio-Hsipaw region. Additionally, the 36th Division continued its eastward push and eventually linked up with the 50th Division in the Kyaukme area by the end of the month before being reassigned to Slim’s 14th Army.

Looking south, the 74th Indian Brigade and West African forces advanced toward Kolan, while the 26th Indian Division established a new beachhead in the Letpan-Mae region. The 154th Regiment maintained its position near the Dalet River, preventing the remainder of the 82nd West African Division from joining the offensive. On March 23, General Miyazaki decided to launch an attack on Kolan. Although the assault achieved moderate success, Miyazaki soon recognized that he was outnumbered and opted to begin a final withdrawal toward the An Pass, completing this by the end of the month.

 

Meanwhile, on March 17, the 121st Regiment sent its 3rd Battalion to engage the enemy in the Sabyin area and hold their position along the Tanlwe River for as long as possible. Despite strong resistance from the Japanese, British-Indian forces managed to cross the Tanlwe by March 27 and successfully captured Hill 815 two days later. By March 30, the 22nd East African Brigade had also reached Letpan when High Command decided to relieve the units of the 26th Division and return them to India.

In a related development, tensions were rising in French Indochina, where the local government refused to permit a Japanese defense of the colony. By early March, Japanese forces began redeploying around the main French garrison towns in Indochina. The Japanese envoy in Saigon Ambassador Shunichi Matsumoto declared to Governor Admiral Jean Decoux that since an Allied landing in Indochina was inevitable, Tokyo command wished to put into place a "common defence" of Indochina. Decoux however resisted stating that this would be a catalyst for an Allied invasion but suggested that Japanese control would be accepted if they actually invaded. This was not enough and Tsuchihashi accused Decoux of playing for time. On 9 March, after more stalling by Decoux, Tsuchihashi delivered an ultimatum for French troops to disarm. Decoux sent a messenger to Matsumoto urging further negotiations but the message arrived at the wrong building. Tsuchihashi, assuming that Decoux had rejected the ultimatum, immediately ordered commencement of the coup.

The 11th R.I.C. (régiment d'infanterie coloniale) based at the Martin de Pallieres barracks in Saigon were surrounded and disarmed after their commanding officer, Lieutenant-Colonel Moreau, was arrested. In Hue there was sporadic fighting; the Garde Indochinoise, who provided security for the résident supérieur, fought for 19 hours against the Japanese before their barracks was overrun and destroyed. Three hundred men, one third of them French, managed to elude the Japanese and escape to the A Sầu Valley. However, over the next three days, they succumbed to hunger, disease and betrayals - many surrendered while others fought their way into Laos where only a handful survived. Meanwhile, General Eugène Mordant led opposition by the garrison of Hanoi for several hours but was forced to capitulate, with 292 dead on the French side and 212 Japanese. An attempt to disarm a Vietnamese garrison ended badly for the Japanese when 600 of them marched into Quảng Ngãi. The Vietnamese nationalists had been armed with automatic weapons supplied by the OSS parachuted nearby at Kontum. The Japanese had been led to believe that these men would readily defect but the Vietnamese ambushed the Japanese. Losing only three killed and seventeen wounded they inflicted 143 killed and another 205 wounded on the Japanese before they too were overcome. A much larger force of Japanese came the next day but they found the garrison empty. In Annam and Cochinchina only token resistance was offered and most garrisons, small as they were, surrendered. Further north the French had the sympathy of many indigenous peoples. Several hundred Laotians volunteered to be armed as guerrillas against the Japanese; French officers organized them into detachments but turned away those they did not have weapons for. In Haiphong the Japanese assaulted the Bouet barracks: headquarters of Colonel Henry Lapierre's 1st Tonkin Brigade. Using heavy mortar and machine gun fire, one position was taken after another before the barracks fell and Lapierre ordered a ceasefire. Lapierre refused to sign surrender messages for the remaining garrisons in the area. Codebooks had also been burnt which meant the Japanese then had to deal with the other garrisons by force. In Laos, Vientiane, Thakhek and Luang Prabang were taken by the Japanese without much resistance. In Cambodia the Japanese with 8,000 men seized Phnom Penh and all major towns in the same manner. All French personnel in the cities on both regions were either interned or in some cases executed. The Japanese strikes at the French in the Northern Frontier in general saw the heaviest fighting. One of the first places they needed to take and where they amassed the 22nd division was at Lang Son, a strategic fort near the Chinese border.

The defences of Lang Son consisted of a series of fort complexes built by the French to defend against a Chinese invasion. The main fortress was the Fort Brière de l'Isle. Inside was a French garrison of nearly 4000 men, many of them Tonkinese, with units of the French Foreign Legion. Once the Japanese had cut off all communications to the forts they invited General Émile Lemonnier, the commander of the border region, to a banquet at the headquarters of the Japanese 22nd Division. Lemonnier declined to attend the event, but allowed some of his staff to go in his place. They were then taken prisoner and soon after the Japanese bombarded Fort Brière de l'Isle, attacking with infantry and tanks. The small forts outside had to defend themselves in isolation; they did so for a time, proving impenetrable, and the Japanese were repelled with some loss. They tried again the next day and succeeded in taking the outer positions. Finally, the main fortress of Brière de l'Isle was overrun after heavy fighting. Lemonnier was subsequently taken prisoner himself and ordered by a Japanese general to sign a document formally surrendering the forces under his command. Lemonnier refused to sign the documents. As a result, the Japanese took him outside where they forced him to dig a grave along with French Resident-superior (Résident-général) Camille Auphelle. Lemonnier again was ordered to sign the surrender documents and again refused. The Japanese subsequently beheaded him. The Japanese then machine-gunned some of the prisoners and either beheaded or bayoneted the wounded survivors.

Lang Son experienced particularly intense fighting, with the 22nd Division relentlessly assaulting the 4,000-strong garrison for two days until the main fortress was captured. The Japanese then advanced further north to the border town of Dong Dang, which fell by March 15. The battle of Lạng Sơn cost the French heavy casualties and their force on the border was effectively destroyed. European losses were 544 killed, of which 387 had been executed after capture. In addition 1,832 Tonkinese colonial troops were killed (including 103 who were executed) while another 1,000 were taken prisoner. On 12 March planes of the US Fourteenth Air Force flying in support of the French, mistook a column of Tonkinese prisoners for Japanese and bombed and strafed them. Reportedly between 400 and 600 of the prisoners were killed or wounded. 

Nonetheless, the coup was highly successful, with the Japanese subsequently encouraging declarations of independence from traditional rulers in various regions. On 11 March 1945, Emperor Bảo Đại was permitted to announce the Vietnamese "independence"; this declaration had been prepared by Yokoyama Seiko, Minister for Economic Affairs of the Japanese diplomatic mission in Indochina and later advisor to Bao Dai. Bảo Đại complied in Vietnam where they set up a puppet government headed by Tran Trong Kim and which collaborated with the Japanese. King Norodom Sihanouk also obeyed, but the Japanese did not trust the Francophile monarch. Nationalist leader Son Ngoc Thanh, who had been exiled in Japan and was considered a more trustworthy ally than Sihanouk, returned to Cambodia and became Minister of foreign affairs in May and then Prime Minister in August. In Laos however, King Sisavang Vong of Luang Phrabang, who favoured French rule, refused to declare independence, finding himself at odds with his Prime Minister, Prince Phetsarath Ratanavongsa, but eventually acceded on 8 April.

March 1945, saw US forces advance in Luzon, overcoming Japanese defenses through strategic maneuvers, while guerrilla activities intensified amid challenging terrain and heavy resistance. Meanwhile, in Burma, British-Indian forces advanced against Japanese troops, capturing key locations and in French Indochina the Japanese unleashed a brutal coup d'etat ushering in independence movements.

- 172 - Pacific War Podcast - Tokyo Great Air Raid - March 4 - 11 - , 1945

Last time we spoke about the Fall of Manila. General LeMay's B-29 bombers wreaked havoc on Japan, targeting key factories at a high cost. On February 19, US Marines landed on Iwo Jima, facing fierce Japanese resistance and heavy casualties. By February 23, after relentless fighting and harsh conditions, they raised the American flag atop Mount Suribachi, marking a hard-won victory. This moment inspired a legacy for the Marine Corps, as battles raged on in the Pacific. Meanwhile troops attacked General Kobayashi's defenses at Mounts Pacawagan and Mataba, struggling to gain ground. Reinforcements arrived, leading to coordinated assaults, but progress was slow. Meanwhile, General Yamashita reorganized his forces in response to increased guerrilla activity. As American divisions advanced, they faced fierce resistance but gradually secured key positions. Guerrilla leader Volckmann disrupted Japanese supply lines, significantly impacting their operations. Amidst the chaos, a daring rescue mission freed over 2,000 internees, though it provoked brutal reprisals against civilians.

Today we are continuing with the ongoing battle over Iwo Jima. By the end of February, Colonel Liversedge’s 28th Marines had successfully secured Mount Suribachi, while the other regiments from the 3rd, 4th, and 5th Marine Divisions advanced toward the O-2 Line, situated beyond Airfield No. 2. This location was where General Kuribayashi maintained his primary defensive positions, which were heavily fortified with caves, tunnels, and traps. On March 1, General Rockey continued his offensive on the left flank as the fresh 28th Marines moved through the weary 27th Marines, led by Colonel Wornham, and launched an assault on Hill 362A and its adjacent positions. The corps' 155mm howitzers and 5th Division artillery commenced firing a preparation at K-minus 45 minutes. One battleship and two cruisers from the gunfire and covering force added their heavy fires from 08:00 to 08:30. Aircraft from the support carrier group delivered strikes throughout the day, but did not participate in preparation for the attack. This proved one of the busiest days for Task Force 54 since D-Day as fire support ships dueled with enemy shore batteries until late afternoon. Shortly after dawn enemy guns in the northern part of the island opened up, and at 07:25 the destroyer Terry took a direct hit by a 6-inch shell, suffering heavy casualties. The battleship Nevada immediately engaged these hostile installations, and after completing their mission in support of the landing force, the cruisers Indianapolis and Pensacola shifted to counter battery fire. At 10:25 the destroyer Colhoun was hit by a major-caliber projectile, and soon after this enemy shells straddled the destroyer Stembel. Counter Battery fire continued throughout the day with the Nevada destroying one casemated gun and starting a fire in another emplacement, while the Pensacola's batteries accounted for a third Japanese gun.

Following the robust aerial, naval, and artillery bombardment, Liversedge’s forces achieved some initial success, including capturing the hilltop, but were ultimately halted by intense machine-gun fire from Nishi Ridge to the north. However, the 3rd Battalion along the coast managed to advance approximately 350 yards against lighter resistance. In the center, General Erskine also pressed forward beyond Airfield No. 2, with Colonel Withers’ 21st Marines advancing north and northeast about 500 yards into the incomplete Airfield No. 3. At the same time, General Cates continued to send his troops into the fray. Colonel Jordan’s 24th Marines replaced Colonel Wensinger’s exhausted 23rd Marines on the left and fought to dislodge the enemy from Hill 382. They succeeded in advancing about 100 yards along the division's left boundary and 50 yards on the right, establishing a foothold on elevated terrain overlooking Minami village. Further south, Colonel Lanigan committed only his 1st Battalion to eliminate the salient around the Amphitheater and Turkey Knob, but this assault was again met with fierce Japanese gunfire.

This relief enabled Erskine to initiate a late two-regiment offensive, with the 21st Marines on the left and Colonel Kenyon’s 9th Marines on the right, although this effort did not achieve any significant progress. The following day, the assault persisted, but the 9th Marines made minimal headway against a strong enemy position on the right, while the 21st Marines advanced toward the base of Hill 362B and the southern edge of Airfield No. 3. Concurrently, Liversedge’s 28th Marines successfully cleared Hill 362A and moved toward Nishi Ridge, where they repelled a fierce counterattack by 150 Japanese soldiers. Colonel Graham’s 26th Marines were once again deployed to fill the gap between the 3rd and 5th Marine Divisions, managing to gain approximately 500 yards to the north. Jordan’s 24th Marines finally captured Hill 382 and advanced about 300 yards on the left flank. Meanwhile, Lanigan’s 1st Battalion made another unsuccessful attempt to infiltrate and take the high ground north of Turkey Knob. As described by an intelligence officer with the 4th Marine Division “As a result of a close study of the enemy's recent defensive action, aided by observation from OP's and air reconnaissance, the following explanation is suggested of the enemy's defense in this Div's Z of A. The enemy remains below ground in his maze of communicating tunnels throughout our preliminary arty fires. When the fire ceases he pushed OP's out of entrances not demolished by our fires. Then choosing a suitable exit he moves as many men and weapons to the surface as he can, depending on the cover and concealment of that area, often as close as 75 yards from our front. As our troops advance toward this point he delivers all the fire at his disposal, rifle, machine-gun, and mortar. When he has inflicted sufficient casualties to pin down our advance he then withdraws through his underground tunnels most of his forces, possibly leaving a few machine gunners and mortars. Meanwhile our Bn CO has coordinated his direct support weapons and delivers a concentration of rockets, mortars and artillery. Our tanks then push in, supported by infantry. When the hot spot is overrun we find a handful of dead Japs and few if any enemy weapons. While this is happening, the enemy has repeated the process and another sector of our advance is engaged in a vicious fire fight, and the cycle continues.” 

Meanwhile the remainder of the 25th Marines managed to advance 300 yards along the coast without facing any opposition. On March 3, the capture of Hill 362A enabled flame-thrower tanks to assist in the advance northward. The 5th Marine Division prepared to press on with its assaults through Nishi Ridge and Hill 362B. The majority of the 28th Marines faced strong resistance as they moved forward over 200 yards. Liversedge’s 1st Battalion and Graham’s 1st Battalion executed a coordinated attack to take the main enemy positions ahead of them. Meanwhile, the remainder of the 26th Marines surged forward, achieving a gain of over 500 yards, which allowed them to relieve Kenyon’s 3rd Battalion and secure the summit of Hill 362B.

In the center, the 9th Marines remained in a stalemate, while the 21st Marines launched a vigorous attack to the northeast, successfully capturing the summit of Hill 357 at the eastern edge of the Motoyama Plateau. They then attempted another assault southeast toward Hill 362C, which resulted in a modest gain of about 250 yards. Meanwhile, in the 4th Marine Division’s sector, Wensinger’s 23rd Marines were deployed in the center, where determined Japanese defenders continued to thwart intense American assaults, despite the partial reduction of the Turkey Knob blockhouse. To the left, the 24th Marines resumed their offensive southeast, advancing up to 350 yards in the center. During the eight days of deadlock and fierce conflict in the Hill 382 and Turkey Knob areas, the weather had been generally favorable. Mild temperatures and fair skies predominated, although early in the morning ground haze combined with smoke to limit observation, and on a few days light showers fell in the afternoon. Night temperatures sometimes went below 60°F, and it was then that tired Marines were grateful for the characteristic subterranean heat of the island that warmed their foxholes. The next day, March 4, dawned gray and sullen, and intermittent showers fell from the overcast skies. Visibility was so limited that all air strikes were canceled and aerial observation seriously curtailed.

On the right, Cates’ Marines pressed the attack southeast but could only gain 150 yards against the defenders' fierce resistance. To the left, after a failed Japanese infiltration attempt overnight to gather food and water, both the 9th and 21st Marines made no progress with their costly eastward assaults. Finally, supported closely by flame-throwing tanks and combat engineers, Rockey’s Marines fought fiercely but achieved only minor advances, prompting Wornham’s 27th Marines to be thrown back into the battle to reinforce the two battered assault regiments. March 5 was then dedicated to reorganizing and resupplying the three Marine Divisions in preparation for a renewed effort the next day. Additionally, the reserve 3rd Marines, led by Colonel James Stuart, were sent back to Guam without having landed on Iwo Jima.

The three divisions accordingly resumed the offensive on March 6 after a terrific artillery and naval gunfire bombardment. First, on the left, Erskine attacked with his three regiments abreast yet failed to make any significant advance. Then, in the center, the 9th and 21st Marines likewise unsuccessfully attacked towards Hill 362C, though the latter managed to clear the entire Hill 357 area. Lastly, Wensinger’s 23rd Marines passed through the 24th on the division left and pressed on forward against heavy opposition, successfully gaining between 150 and 350 yards while Jordan’s battalions gained up to 150 yards in their front. Additionally, the 25th Marines mopped up in its area and Cates’ Provisional Battalion kept hammering against the Amphitheater-Turkey Knob area. In the knowledge that the battle was swinging irrevocably in favor of the Americans, General Kuribayashi radioed Tokyo: "Our strongpoints might be able to fight delaying actions for several more days. I comfort myself a little seeing my officers and men die without regret after struggling in this inch-by-inch battle against an overwhelming enemy...". The General's predictions were, if anything, on the pessimistic side as his garrison would prolong the battle for another three weeks.

Although the fighting was dragging terribly, on this day Brigadier-General Ernest Moore successfully landed on Airfield No. 1 alongside 28 P-51s and 12 P-61s of the 15th Fighter Group to take over control of island air activities. The following day, the Island Commander, Major-General James Chaney, assumed responsibility for base development, air defense, and operation of the airfields. Meanwhile, Schmidt was continuing his coordinated offensive, with the 28th Marines meeting only scattered resistance as it pushed 500 yards north; the 26th Marines overrunning the enemy defenses and gaining about 150 yards before resistance stiffened once again; the 27th Marines attacking on a narrow front but likewise gaining only 150 yards; the 21st Marines achieving tactical surprise to reach Hill 331 and then pushing 250 yards more to Hill 362C, which was ultimately seized as well; the 9th Marines ferociously attacking east but gaining only 200 yards before a rain of fire stopped them; the 23rd Marines recovering from a savage Japanese night counterattack and then pushing around 150 yards against strong resistance; the 24th Marines only progressing over 50 yards as it neutralized a number of enemy defenses; and the 25th Marines and the Provisional Battalion continuing secondary operations against the Amphitheater-Turkey Knob area.

On March 8, Rockey pressed on toward the northeast coast, with the 28th Marines advancing against minimal resistance, gaining between 300 and 500 yards along the shoreline. Meanwhile, the 26th Marines faced a complete stalemate against the intricate network of pillboxes and interconnected caves that had once comprised the village of Kita. The 27th Marines managed to advance approximately 150 yards with tank support. In the center, the 21st Marines shifted northeast again, successfully gaining 300 yards through the last organized resistance in the area, while the 9th Marines captured Hill 362C and continued their eastward assault, reaching the edge of the plateau overlooking the beach and initiating a flanking maneuver south of Hill 331. On the right flank, the 23rd and 24th Marines continued their attacks but made little headway against the enemy's formidable defenses.

That night, General Senda launched a strong counterattack that caught the Americans off guard. Two of Senda’s orderlies would survive and report what occurred during the daring counterattack. Many of his troops believed that Inoue was a superior leader who inspired his men to perform outstanding feats of bravery; others thought he was a maniac. The sight of the Stars and Stripes flying on top of Mount Suribachi had filled him with increasing rage. He is quoted as saying: "We shall destroy their banner, we shall replace it with ours in the name of the great Emperor and the great people of Japan." Inoue was in charge of the Naval Guard Force who manned the shore guns that sank and damaged many of the US warships and landing craft, and was described as a bombastic and temperamental character, a fine swordsman, heavy drinker, and womanizer. His bizarre plan almost beggars belief. The Captain was certain that the airfields would be lightly defended by service troops. He and his men would move southward, destroying B29 bombers as they passed; climb Mount Suribachi and tear down the Stars and Stripes; and replace it with the Rising Sun as an inspiration to all Japanese troops on the island.  However this never came to be. The determined defenders, bolstered by heavy artillery and machine-gun fire, repelled the assault, resulting in approximately 800 Japanese casualties. Under relentless pressure in a shrinking area where most critical terrain features had been seized, the disorganized Japanese forces saw a fleeting opportunity to escape destruction, raid American-controlled airfields, and reclaim Mount Suribachi with this counterattack. However, its failure effectively depleted Senda’s remaining strength and chances for continued resistance. The following day, Cates resumed the offensive, with the 23rd Marines making minor gains along their front, while Jordan’s 3rd Battalion achieved a notable breakthrough of 300 yards.

Furthermore, the Provisional Battalion was disbanded, and Lanigan’s 2nd Battalion assumed control of the Amphitheater-Turkey Knob region. In the center, Erskine persisted in his advance toward the sea, with patrols from the 9th and 21st Marines successfully reaching the beach as American forces continued to secure the area. Meanwhile, to the left, Rockey faced significant resistance, with his troops soon coming under intense and precise fire from elevated positions extending southeast from Kitano Point. Consequently, the 26th and 27th Marines remained in a stalemate while the 28th Marines moved forward. On March 10, Liversedge’s men advanced approximately 40 yards across extremely challenging terrain and against fierce opposition, while Graham’s 2nd Battalion gained an additional 75 yards, with the rest of the 26th and 27th Marines still held in place. Over the past 14 days, Rockey’s 5th Marine Division advanced 3,000 yards along the west coast, ultimately pushing Kuribayashi’s forces into a final pocket at the northern tip of the island. 

In a dispatch to Tokyo on March 10, General Kuribayashi summed up the Japanese situation in this manner: “Although the attacks of the enemy against our Northern districts are continuing day and night, our troops are still fighting bravely and holding their positions thoroughly… 200 or 300 American infantrymen with several tanks attacked "Tenzan" all day. The enemy's bombardments from one battleship (or cruiser), 11 destroyers, and aircraft are very severe, especially the bombing and machine-gun fire against Divisional Headquarters from 30 fighters and bombers are so fierce that I cannot express nor write here.” Not until 15 bloody days later did Marines eliminate the last pocket of organized enemy resistance in the northern end of the island. By D+19 all that remained for the enemy force was to fight and die for the Emperor.

This advance came at a significant cost, with Rockey suffering 1,098 men killed and 2,974 wounded during this time. In the center, the 21st Marines reported that all organized resistance in their area had been eliminated, while the 9th Marines moved toward the beach, facing harassment from enemy fire from a resisting pocket on their right. Nevertheless, Erskine’s 3rd Marine Division successfully secured the airfield areas and only needed to eliminate this last remaining pocket in their zone. However, personnel losses during this 14-day campaign were substantial, with Erskine losing 831 men killed and 2,241 wounded.

Finally, Cates took over from the 24th Marines as he initiated his final offensive eastward. Consequently, the 23rd Marines advanced southeast with minimal resistance, covering approximately 700 yards before stopping at a strategic high ground about 500 yards from the beach, while patrols moved toward the coast near Tachiiwa Point. Simultaneously, Lanigan's 1st and 3rd Battalions pushed 600 yards southeast against stronger opposition and successfully occupied the key terrain southwest of Higashi. Meanwhile, the 2nd Battalion advanced northeast to join them, effectively driving the remaining enemy forces into a small pocket in that area. Over the last 14 days, Cates' 4th Marine Division engaged in relentless assaults, fighting fiercely from Charlie-Dog Ridge past Hill 382, the Amphitheater, Turkey Knob, through Minami, and the formidable defenses northeast of Hill 382, nearly reaching the coast. 

The Japanese conducted an astute defense in this sector. General Kuribayashi had planned well, but much credit for execution of the plan in the 4th Marine Division zone must go to General Senda, who commanded the 2nd Mixed Brigade and exercised tactical control during the battle. Enemy weapons and minefields were well placed to take maximum advantage of terrain features, fire control was excellent when judged by Japanese standards, and camouflage discipline outstanding. Machine-gun positions controlled draws, while mortars were disposed to deliver fire on routes of approach, including the crests, forward, and reverse slopes of ridges. The one obvious mistake made by the Japanese in this long, grueling defense to the death was the night counterattack of March 8. This action cost them many lives and gained no advantage. Even this rather hopeless plunge can be somewhat justified, however, when the situation that existed then is seen from the Japanese point of view. By March 8, the enemy was under heavy, constant pressure in an ever-shrinking area where most of the critical terrain features had been captured. He was quickly becoming dispossessed and disorganized, with few courses of action remaining. Because communications were undoubtedly badly disrupted, it is possible that the Japanese facing the 4th Division did not realize just how hopeless his cause appeared and therefore harbored some hope that the counterattack might not be in vain. The cost was significant, with Cates suffering 848 men killed and 2,836 wounded. 

While the battle raged on Iwo Jima, General LeMay was also preparing for a major raid on Tokyo, known as Operation Meetinghouse. After a precision strike by 192 B-29 bombers against Musashi on March 4, which resulted in minimal damage due to heavy cloud cover, a decision was made to move away from the 21st Bomber Command's traditional focus on precision bombing. This eighth fiasco at Musashi marked the end of a well-defined phase of 21st Bomber Command's operations. The effort to knock out the Japanese aircraft industry by high-altitude, daylight precision bombing of carefully selected targets had failed. Production of aircraft engines, not grossly off scheduled programs when 21st Bomber Command came to the Marianas, fell off sharply during the last two months of 1944 and production of aircraft declined slightly during the same period. In neither case, however, could the shortages be accounted for by destruction wrought by the B-29's; indeed, the output of Franks at Ota had decreased from 300 a month to 100 before the first air strike. Not one of the nine high-priority targets had been destroyed, although Akashi had been effectively crippled and production had been slowed down at Mitsubishi's engine and assembly plants at Nagoya and at Nakajima-Ota. Musashi had suffered only 4% damage after 835 B-29 sorties had been sent against it; Navy planes had done more harm in a single strike. Probably the indirect effects of the B-29 raids were most important: with the fall of Saipan, Japanese industrialists had begun to lose confidence in their supposed immunity from air attack. Although under governmental pressure for increased production, they began, with the first attacks on Nakajima and Mitsubishi, to hunt for underground or forest cover, and the official directive for dispersal issued in mid-January merely served to quicken a process already well under way. This radical change in manufacturing techniques, never as efficiently conducted as the similar movement in Germany had been, explains in part the slowdown in production in late 1944 and early 1945.  In 22 missions comprising 2,148 sorties, the command dropped 5,398 tons of bombs on Japan targeting the Imperial aircraft industry, but only about half of the bombers hit primary targets. Losses were substantial, largely due to fierce enemy interceptors and the lengthy overwater journey from the Marianas to Japan, which lacked any friendly bases for refueling or repairs.

As a result of the high costs associated with unescorted daylight missions, the susceptibility of Japanese cities to incendiary attacks, and the minimal impact of precision bombing with high explosives, General Arnold ultimately opted for a comprehensive incendiary campaign. In preparation for the forthcoming assault on Okinawa, LeMay was tasked with initiating a series of intensive incendiary strikes from low altitudes. This lower bombing altitude would enhance accuracy, increase bomb load, and prolong the lifespan of B-29 engines. Although this approach carried risks, LeMay believed that the intense Japanese anti-aircraft fire was not overly threatening, as only two B-29s had been lost due to flak alone. He also decided to conduct these missions at night, which would decrease the likelihood of heavy cloud cover and strong winds, simplify navigation, and enable the bombers to reach the two new emergency airstrips at Iwo Jima by dawn. The first mission was set to commence immediately, with 334 B-29s from the 73rd, 313th, and 314th Bombardment Wings taking off in the late afternoon of March 9, carrying approximately 2,000 tons of bombs. The target was a rectangular area in northeastern Tokyo known as Zone I, measuring about 4 by 3 miles and encompassing most of Asakusa, Honjo, and Fukagawa Wards. After a turbulent journey, the initial pathfinders successfully identified their targets under favorable weather conditions and marked them shortly after midnight with fires

However LeMay's decision came late. With the first mission set for the night of March 9, the field orders were not cut until the 8th. Although operational details would vary significantly from normal practice, there was no time to consult Washington as was so frequently done. Arnold was not even informed of the revolutionary plans until the day before the mission. The decision to attack at night ruled out the command's standard technique of lead-crew bombing. Formation flying at night was not feasible, and with flak rather than enemy fighters the chief danger, a tight formation would be a handicap rather than a source of defensive strength. With planes bombing individually from low altitudes, bomb loads could be sharply increased, to an average of about six tons per plane. Lead squadron B-29s carried 180 x 70-pound M47s, napalm-filled bombs calculated to start "appliance fires," that is, fires requiring attention of motorized fire-fighting equipment. Other planes, bombing on these pathfinders, were loaded with 24 x 500-pound clusters of M69s. Intervalometers were set at 100 feet for the pathfinders, 50 feet for the other planes. The latter setting was supposed to give a minimum density of 25 tons (8333 M69s) per square mile.

Late reports indicated widespread fires that forced formations to search extensively for targets, with visibility severely hampered by smoke and bomb runs complicated by turbulence from intense heat waves. During the three-hour assault, a total of 279 B-29 bombers targeted Tokyo, successfully dropping 1,665 short tons of bombs on the primary objective. Additionally, 19 Superfortresses, unable to reach Tokyo, attacked alternative or last-resort targets. The Japanese were taken completely by surprise by this tactical shift, resulting in only moderate resistance; intense anti-aircraft fire destroyed 14 B-29s and damaged another 42, while enemy interceptors had no significant effect. The fires were so intense that they nearly extinguished themselves by mid-morning, only halted by wide gaps like rivers. Subsequent photographs revealed that 15.8 square miles had been devastated, including 18% of the industrial sector, 63% of the commercial area, and the core of the densely populated residential district. Tokyo’s highly effective firefighting system was also caught off guard, leading to the destruction of 95 fire engines and the deaths of 125 firefighters, while lightweight buildings were completely consumed along with their contents. Little rubble remained; only a few fire-resistant structures, marked by heat damage, stood in the devastated areas. In total, 267,171 buildings were destroyed, 83,793 people lost their lives, 40,918 were injured, and 1,008,005 were left homeless. Moreover, it took 25 days to recover all the bodies from the debris. Radio Tokyo referred to the raid as “slaughter bombing,” with one broadcast stating that “the sea of flames engulfing the residential and commercial districts of Tokyo was reminiscent of the holocaust of Rome, caused by Emperor Nero.”

The attack significantly undermined the morale of Japanese civilians, and along with other firebombing raids in March, it led many to believe that the war situation was worse than their government had acknowledged. In response, the Japanese government implemented a mix of repression, including severe penalties for those accused of disloyalty or spreading rumors, and launched an ineffective propaganda campaign aimed at restoring confidence in the nation's air and civil defense efforts. Meanwhile, LeMay and Arnold viewed the operation as a considerable success. As Tokyo mourned its losses, another 313 B-29s were sent on the afternoon of March 11 to execute a similar strike on Nagoya; however, due to minimal wind to spread the fires from the widely dispersed bombs, the results were less impressive. Nonetheless, only one B-29 was lost during the raid, with another 20 sustaining damage. It became evident, as LeMay had predicted, that the Japanese lacked effective tactics for nighttime interception. Now, attention shifts to Burma to report on the ongoing Chinese-British-Indian offensives. On General Slim’s primary front, General Stopford’s 33rd Corps continued its vigorous advance toward Mandalay, while General Cowan’s 17th Indian Division successfully made its way to the Meiktila area in the Japanese rear. In response, Generals Kimura and Katamura sent several reinforcements to this crucial area, but only the 1st Battalion, 168th Regiment, led by Colonel Yoshida, managed to arrive in time to establish some defenses in the town, quickly transforming buildings in Meiktila into bunkers and strongpoints. On February 28, Cowan dispatched the 63rd Brigade to launch an attack from the west and the 48th Brigade to advance from the north along the Mahlaing-Meiktila road, while the 255th Tank Brigade executed a wide flanking maneuver to approach from the east. As a result, the 63rd Brigade secured Kyaukpyugon and set up a roadblock southwest of Meiktila; the 48th Brigade advanced to a bridge over a chaung approximately a mile from the town; and the 255th Brigade fought its way to Kyigon and Khanda, successfully destroying several bunkers near Point 860.

On March 1, following a heavy air and artillery bombardment, Cowan’s three brigades began to push into Meiktila despite fierce resistance. The 48th Brigade, bolstered by a tank squadron, advanced down the Mandalay-Meiktila road, quickly clearing Kyigon before entering the town, where they reached within 100 yards of the railroad line before the attack was halted in the late afternoon. To the east, the majority of the 255th Tank Brigade captured Point 860 and began clearing the camouflaged bunkers along the ridgeline, while a combined force of tanks and grenadiers advanced to within 200 yards of the railroad station before being recalled. Meanwhile, the 63rd Brigade, supported by a tank squadron, cleared the village of Kanna and continued past it to secure the railroad line and the main Kyaukpadaung-Meiktila road. The following day, the 17th Indian Division tightened the encirclement around Meiktila, inflicting significant casualties on the outnumbered defenders and destroying numerous enemy bunkers.

On March 3, the three brigades commenced the task of eliminating the last remaining Japanese forces in and around Meiktila. They faced intense sniper and machine-gun fire from every building. However, due to the tanks' superior firepower, the Japanese strongholds were systematically taken down one by one. By the end of the day, the town was cleared, with an estimated 2,000 Japanese troops killed, including Colonel Yoshida. Additionally, 47 field pieces and anti-tank guns were captured, and the supply dumps surrounding Meiktila were secured. Cowan now needed to organize the town's defenses, anticipating a swift and fierce Japanese counterattack. Immediately after the town's capture, Kimura ordered the 18th Division to work with the weakened 49th Division to reclaim Meiktila, while Katamura reinforced General Naka with the majority of the 119th and 214th Regiments, a strong artillery unit, and the battered 14th Tank Regiment. Following the capture of Meiktila, Cowan’s forces spent the next few days clearing the area of any remaining snipers and stragglers. For the town's defense, Cowan assigned each brigade and the divisional infantry to four sectors, each featuring a heavily fortified redoubt. He also tasked the 99th Brigade with defending Kyigon and Meiktila’s airfield. To maintain the initiative for the 17th Division, Cowan aggressively deployed strong mobile columns of tanks, mechanized artillery, and infantry to disrupt the Japanese formations as they approached Meiktila. Consequently, while the 18th and 49th Divisions advanced, Ywadan and Nyaungaing were secured on March 5. In the following days, the main roads leading to Mahlaing, Kyaukpadaung, Pyawbwe, Thazi, and Mandalay were cleared, and the enemy units of the 214th Regiment at Thangongyi and Yego were successfully repelled on March 8.

General Naka was now prepared to initiate his primary assault on Meiktila, instructing his units to concentrate their efforts north of the town, while the 214th Regiment made an unsuccessful attempt to move southwest to connect with the 49th Division. In response to these movements, on March 10, Cowan sent a robust tank-infantry force along the Mahlaing road to escort a previously dispatched column back to Meiktila, successfully inflicting significant casualties on the 56th Regiment as the British-Indians secured the Leindaw-Kyanngyagon area. However, the troops faced harassment from artillery fire originating from south of Myindawgan Lake, prompting Cowan to launch another armored sweep on March 14 to eliminate this threat. Although the 55th Regiment managed to capture the hill north of Meiktila after Cowan’s tanks and infantry withdrew, the Japanese forces were unable to prevent their return, which resulted in further heavy losses. Concurrently, other tank-infantry units disrupted the advance of the 49th Division, effectively delaying the assembly of Japanese forces to the south and east of Meiktila until March 18. Additionally, a strong raid by the Komatsubara Unit was successfully repelled on March 14. In Stopford’s sector, the 19th Division was preparing to launch its final offensive southward toward Mandalay, while the 2nd and 20th Divisions, after fierce fighting to expand their bridgeheads, were advancing east to assault the southern approaches to Mandalay. With close support from artillery and aircraft, General Rees’ forces successfully breached the primary defenses of Lieutenant-General Yamamoto Kiyoe’s 15th Division, reaching the northern outskirts of Mandalay by March 7.

As the assault continued, British-Indian forces were set to enter the city on March 9. However, the determined defenders clung to Mandalay Hill and Fort Dufferin, aiming to extend the conflict and fight to the death. While Mandalay was under siege, the 62nd Brigade stealthily advanced east to Maymyo on March 11, catching the garrison off guard. The next day, Mandalay Hill ultimately fell while Fort Dufferin was being heavily bombarded within the city. By mid-March, the 2nd Division was nearing the capture of Ava, and the 20th Division was steadily advancing east to sever the supply routes from Mandalay to the south. In northern Burma, General Sultan was also pursuing his offensive. After establishing a bridgehead at Myitson, General Festing’s 36th British Division faced minimal resistance and successfully took Mongmit on March 9 before continuing southward to Mogok. To the east, the 38th Chinese Division encountered only weak delaying positions as it moved towards Lashio, which was successfully occupied by March 7. At this point, the 56th Division, now independently commanding this area, was gradually retreating towards Hsipaw and Kyaukme. Although General Sun paused his advance until the Generalissimo granted permission to resume the offensive later in the month.

Mountbatten feared that if more Chinese troops were withdrawn from Burma it might not be possible to take Rangoon before the monsoon rains began. This was an unpleasant prospect, so Mountbatten went to Chungking on March 8 for two days of conference with the Generalissimo. When the conference of March 9 concluded, the Generalissimo, according to the American minutes, said that he would recapitulate his decision of halting the Chinese advance at Lashio. In so doing, he remarked that the details of withdrawal would be settled later and that no final decisions would be made before General Wedemeyer was able to take part in them. Then he stated that unless there was a simultaneous amphibious attack on Rangoon, operations would stop at Lashio and Mandalay and the Allies would assume the defensive. The Chinese would stop at Lashio, but details of their operations between Lashio and Mandalay would be settled later between the staffs. The misunderstanding became quite apparent in mid-March when General Sultan, under whose command the Chinese were, received conflicting orders. Mountbatten ordered Sultan to move his forces southwestward toward Mandalay, yet the Generalissimo directed that the Chinese divisions stay in the Lashio area. As a compromise and to avoid having the Chinese wait idly around Lashio, Sultan suggested that a smaller task force be directed to proceed south. But the Generalissimo and his American advisers stood firm, lest the shift of troops to China be delayed. This in turn caused the British to believe that if the Chinese were not going to advance they should be withdrawn forthwith and end the burden on the line of communications. The 50th Chinese Division began to push south after securing the Namtu region and by mid-March reached Hsipaw. Meanwhile, in South Burma, the 82nd West African Division had taken Dalet, while the 25th Indian Division engaged in a struggle for control of the Ruywa-Tamandu area. Additionally, the 2nd West African Brigade was advancing inland toward An, posing a significant threat to the Japanese rear areas.

Due to the rapid advancement of Slim’s offensive, Admiral Mountbatten had to prioritize air supply for the 14th Army. This situation soon compelled General Christison to send the 25th Indian Division back to India, as his logistical support was becoming increasingly strained. Capturing Tamandu and establishing a Forward Maintenance Area there became essential. After successfully clearing Dokekan, the 74th Indian Brigade crossed the Me Chaung on March 4 to circumvent the main enemy defenses. The British-Indians pressed on, launching attacks on Tamandu in the following days, but the determined defenders put up strong resistance. Eventually, General Miyazaki withdrew most of the 111th Regiment and ordered it to attack the 2nd West African Brigade from the rear, which was finally contained by March 17. With the 25th Division scheduled to withdraw to Akyab by the end of the month, the 74th was reassigned to the 82nd West African Division and launched a final assault on Tamandu on March 11, successfully capturing the abandoned objective. The British-Indians then began to advance towards Kolan, reaching the vicinity of the town by mid-March. Simultaneously, the 154th Regiment counterattacked the West Africans at Dalet, successfully halting the enemy’s advance beyond the river. Meanwhile, the 4th Indian Brigade landed at Mae near Letpan on March 13 from Ramree Island and established a roadblock to prevent enemy escape. In response, the 121st Regiment sent several companies to conduct a delaying action aimed at slowing the enemy's southward advance.

The battle for Iwo Jima intensified as the Marines advanced against fortified Japanese positions, facing heavy resistance and suffering significant casualties while capturing key terrain over several weeks of fierce combat. Meanwhile General LeMay shifted from precision bombing to incendiary raids on Tokyo, resulting in significant destruction and civilian casualties, while Japanese morale plummeted amid military setbacks.

 

- 171 - Pacific War Podcast - The Fall of Manila - February 25 - March 4 - , 1945

Last time we spoke about the invasion of iwo jima. General LeMay's B-29 bombers targeted Japan, inflicting heavy damage on Kobe and Ota's Nakajima factory, though at a cost of lost aircraft. Meanwhile, U.S. forces prepared for the Iwo Jima assault. On February 19, Marines landed amid intense bombardment, facing fierce Japanese resistance. Progress was slow, with heavy casualties. By February 21, they fought to capture Mount Suribachi. Amidst the chaos, kamikaze attacks struck American carriers, causing significant losses and foreshadowing the brutal battles ahead. In the midst of a relentless rain on February 22, Colonel Liversedge led the 28th Marines in a fierce assault on Mount Suribachi, facing determined Japanese resistance. Despite harsh conditions and significant casualties, the Marines pushed forward. On February 23, they reached the summit, raising the American flag to symbolize their hard-fought victory. The Secretary of the Navy, inspired by the moment, declared it would ensure the Marine Corps' legacy for centuries. As battles continued, the Marines faced heavy losses but remained resolute in their mission.

As we last observed in Manila, General Griswold's forces had effectively confined the remnants of Admiral Iwabuchi's troops to Intramuros, the South Port Area, and the Philippine Commonwealth Government buildings located at the southeastern edge of the Walled City. Available information led to the conclusion that the Japanese defenses were strongest on the southern and eastern sides of the Walled City and that the Japanese expected attack from these, the most logical directions. Japanese garrisons in the Legislative, Finance, and Agriculture Buildings just across Padre Burgos Street southeast of Intramuros could cover these approaches. The 37th Division could, of course, take the government buildings before launching an assault on Intramuros, but it would be easier to attack the government buildings after Intramuros fell. Conversely, planners deemed it feasible to strike into Intramuros from the west, since Japanese defenses along the west wall, across Bonifacio Street from the Manila Hotel and the South Port Area, appeared weak. But in this case, American troops would first have to clear the South Port Area and then, advancing from the west, would have to attack toward much of their own supporting artillery. The artillery's best positions for close support were on the north and northeast, across the Pasig, and on the east, in the area south from the General Post Office to the City Hall, and much of the artillery ultimately did fire from these areas. About halfway from the northeast to the northwest corner of Intramuros the ancient wall ended, providing direct access into the Walled City at the Government Mint. The only other obstacle on the north was a low sea wall running along the south bank of the Pasig, and Japanese defenses along the north face appeared weak except at the northeast corner. Planners therefore decided that there would be an excellent chance to execute a successful amphibious assault from the north bank of the Pasig against the north-central side of the Walled City. 

Given that the Japanese defenses were strongest on the southern and eastern sides of the Walled City, and that the ancient wall ended at the Government Mint between the northeast and northwest corners of Intramuros, it was decided to initiate an amphibious attack from the north bank of the Pasig River targeting the north-central section of the Walled City, executed by the 129th Regiment with close artillery support. However, aware that the Japanese had established a complex tunnel system for rapid troop movement within Intramuros, General Beightler deemed it essential to conduct a secondary assault on Quezon Gate near the northeastern entrance to keep the Japanese forces off balance and to split their attention. Since the Japanese had fortified this area with strong pillboxes just inside the walls, the division concluded that heavy artillery would be required to create an additional breach in the thick wall just south of Quezon Gate, where the 145th Regiment would launch its attack. Furthermore, as the Japanese could target the advancing troops with enfilade fire from the three government buildings to the south, Allied artillery would need to neutralize these buildings during the assault on Intramuros. Lastly, the 1st Cavalry Brigade positioned to the west and southwest of Intramuros would block any potential escape routes for Japanese forces from the Walled City.

So far, General MacArthur had severely restricted the employment of air in the metropolitan area. In late January and early February Marine Corps SBDs had bombed or strafed a few pinpointed targets in the North and South Port Areas and had also hit some obvious Japanese gun positions in the open areas of Luneta Park and Burnham Green. One or two strikes may also have taken place against specific targets within Intramuros, but all in all it appears that planes of the Allied Air Forces flew no more than ten or twelve individual sorties against targets within the city after February 3. Before that time both carrier-based and land-based aircraft had presumably limited their strikes to targets within the port areas and to oil storage facilities in Pandacan and Paco Districts. Of course some bombs had gone astray during these strikes and had caused damage within Intramuros, while additional damage within the Walled City had resulted from both American and Japanese artillery fire the first two weeks of the battle for Manila. When approached with General Griswold’s plan to carry out an intensive aerial bombardment against the Walled City, MacArthur once again objected: “The use of air on a part of a city occupied by a friendly and allied population is unthinkable. The inaccuracy of this type of bombardment would result beyond question in the death of thousands of innocent civilians. It is not believed moreover that this would appreciably lower our own casualty rate although it would unquestionably hasten the conclusion of the operations. For these reasons I do not approve the use of air bombardment on the Intramuros district.”

However, General MacArthur had previously issued orders limiting air operations in the metropolitan area, leading him to reject this proposal. Not wanting to rely solely on infantry for the assault, Griswold and Beightler decided to organize a significant artillery preparation, as they were not explicitly prohibited from using artillery. After several unsuccessful attempts to persuade the Japanese in Intramuros to surrender or release the numerous Filipino civilians they were holding hostage, Griswold initiated the bombardment of Intramuros on February 17, creating several breaches in the east wall. On February 22, Allied artillery began targeting the north wall to breach it and eliminate a Japanese stronghold at the Government Mint, while additional guns took up positions for the final barrage before the infantry assault the following morning. Between 07:30 and 08:30 on February 23, the Americans executed the last preparatory bombardment, effectively damaging the walls of Intramuros and covering much of the interior. Once the supporting fire ceased, the infantry assault commenced, with the 3rd Battalion, 129th Regiment swiftly crossing the Pasig River without opposition and advancing through the Government Mint into Intramuros. Simultaneously, the 2nd Battalion, 145th Regiment climbed over the breach south of Quezon Gate and entered through the gate unopposed, quickly moving southwest toward Letran University.

Ten minutes into the assault, Griswold’s artillery resumed fire for the next half hour, deploying high explosives, smoke, and white phosphorus across a 100-yard-wide area between the east and west walls. This aimed to seal off the southern third of Intramuros, preventing the Japanese forces there from observing movements to the north or sending reinforcements. The total artillery and mortar fire supporting the assault amounted to 230 tons, equivalent to over 11,650 rounds. By 08:50, the 129th and 145th Regiments connected at Letran University, with the 129th advancing toward Beaterio Street and Fort Santiago against minimal resistance, while the 145th cleared Letran University and secured the first two blocks southwest of Quezon Gate. At 10:45, the 1st Battalion of the 145th Regiment moved through Parian Gate and headed south. As American troops pushed deeper into Intramuros, the Japanese began to recover from the artillery bombardment, offering sporadic resistance from isolated machine-gun and rifle positions. Nonetheless, the 129th successfully cleared the west wall north of Beaterio Street and captured Fort Santiago in the afternoon. However, the 145th had to halt its advance about four blocks southwest of Quezon Gate as the Japanese started releasing nearly 3,000 civilian hostages from San Augustin and Del Monico Churches. Once the civilian evacuation was complete, American tanks and self-propelled artillery targeted Japanese positions within those churches and other strongholds in the southwestern section of Intramuros. Despite the efforts, the troops were unable to reach the south or west walls before nightfall due to fierce resistance.

Meanwhile, the 1st Squadron, 12th Cavalry, along with the 2nd Squadron, 5th Cavalry, began clearing the South Port Area, facing relatively light opposition except at one strongpoint. Meanwhile, the 1st Squadron, 5th Cavalry, and elements of the 148th Regiment contained the enemy at the government buildings. On February 24, while the 129th was finishing operations at Fort Santiago, the 145th continued its offensive, successfully cornering the last pockets of resistance in its area into the Aquarium, situated in a bastion at the southwest corner of Intramuros. Although the resistance was fierce in this location, a tunnel linking the bastion to the main wall was unexpectedly left unguarded, allowing Company C to break through into the Aquarium with ease. The final assault commenced in the afternoon, resulting in 115 Japanese casualties as the last organized resistance within Intramuros was overcome. In total, approximately 1,000 Japanese were killed, and 25 were captured during the assault on Intramuros, with the Americans suffering 25 killed and 265 wounded. Concurrently, the cavalrymen completed the clearing of the South Port Area and turned their attention to the government buildings, which would necessitate another intensive preparatory bombardment. 

The imposing, columned façade of the Philippine Commonwealth's Legislative Building--the Philippine Capitol--fronted on Padre Burgos Street opposite the southeast corner of Intramuros and lay 150 yards south of the City Hall. About 100 yards south of the Legislative Building was the Bureau of Finance, and another 250 yards to the south-southeast, near the intersection of General Luna and San Luis Streets, lay the main building of the Bureau of Agriculture and Commerce. Architecturally similar to the old Senate and House Office Buildings in Washington DC, the three government structures were modern, earthquake-proof edifices constructed of heavily reinforced concrete. The oblong Legislative Building, with wings four stories high and a central portion rising another two and a half floors, was constructed around two open courtyards. The Finance and Agriculture Buildings, both five-story trapezoids, each featured a central courtyard. The buildings were strong not only by virtue of their construction but because all approaches to them led across wide open ground. Sandbag emplacements and barricades of other types blocked all readily accessible doors and windows, and window-emplaced machine guns covered all approaches. Despite the fact that the Japanese in the three buildings had advantages of position and elevation that permitted them to endanger American and Filipino movements over large areas of Manila, the 14th Corps and the 37th Division at first considered starving the Japanese garrison out. But the two headquarters soon decided this would take too long. Information from prisoners and Filipino hostages who had escaped from the buildings indicated that the Japanese garrisons in the three structures had sufficient strength, ammunition, food, and water to withstand a protracted siege. On February 26, after an hour of final artillery preparation, the 1st Battalion, 148th Regiment entered the ground floor of the Legislative Building from the rear, while the 5th Cavalry attacked the Agriculture Building; however, both units were successfully repelled by the determined defenders. The following day, after a failed attempt to smoke the Japanese out of the Legislative Building, heavy artillery was used to demolish the north and south wings, leaving only the damaged central section, which was subsequently cleared by the infantry.

At the same time, the 5th Cavalry cleared out the apartment building and several nearby structures in preparation for another attack on the Agriculture Building, which commenced on February 28 following a three-hour artillery bombardment that caused significant portions of the building to collapse. Facing no initial resistance, the cavalrymen quickly accessed the remnants of the first floor but soon encountered strong opposition from pockets of resistance at the northwest and southeast corners. With support from tanks and armed with small arms, bazookas, and portable flamethrowers, the 5th Cavalry managed to clear the above-ground debris by nightfall, although a few Japanese soldiers remained hidden in basement areas. Ultimately, on March 1, after a failed appeal for surrender, demolitions along with burning gasoline and oil eliminated the last of the Japanese resistance. During this time, artillery, tanks, and tank destroyers relentlessly bombarded the Finance Building from various angles. Eventually, the 1st Battalion of the 148th Regiment would clear the remnants of this building during their final assaults on March 2 and 3. Late on March 3, Griswold joyfully informed Krueger that organized resistance in the Manila area had come to an end. The cost of reclaiming Manila was significant, with over 1,000 Americans killed and 5,500 wounded in the metropolitan area between February 3 and March 3. In contrast, the Japanese suffered approximately 16,000 fatalities in and around Manila. During periods of calm in the fighting, Japanese troops often vented their anger and frustration on the city's civilians, committing acts of violent mutilation, rape, and massacres in schools, hospitals, and convents. This led to the deaths of at least 100,000 Filipino civilians, both from deliberate actions by the Japanese during the Manila massacre and from artillery and aerial bombardments by American and Japanese forces. If you listened to the very first episode of this podcast series, I actually began it with what is known as the Manila massacre. During lulls in the battle for control of Manila, Japanese troops took their anger and frustration out on the civilians in the city. Violent mutilations, rapes, and massacres occurred in schools, hospitals and convents, including San Juan de Dios Hospital, Santa Rosa College, Santo Domingo Church, Manila Cathedral, Paco Church, St. Paul's Convent, and St. Vincent de Paul Church. The Bayview Hotel was used as a designated "rape center". General Yamashita was convicted as a war criminal for the Manila massacre, although Admiral Iwabuchi's marines had committed the atrocities and Yamashita had earlier ordered him to evacuate Manila. 

By the end of the Battle of Manila, the public transportation system no longer existed; the water supply and sewage systems needed extensive repairs; the electric power facilities did not function; most of the streets needed repaving; and 39 out of 100 or more large and small bridges had been destroyed, including the 6 over the Pasig River. The University of the Philippines and the Philippine General Hospital were largely irreparable. Lower class residential districts north of the Pasig and upper class apartments south of the river had been destroyed; the Philippine Commonwealth's government's center had been wiped out; the 400-year-old landmark of Intramuros had been nearly razed; severe damage had been inflicted on the economically important installations in the North and South Port Areas; and the industrialized Paco and Pandacan Districts had been badly battered. Many buildings still standing would ultimately have to be torn down as unsafe for occupancy. Millions upon millions of dollars' worth of damage had been done and, as a final shocking note of tragedy, an estimated 100000 Filipino civilians had lost their lives during the battle.

However, Manila was officially liberated, marking the end of nearly three years of Japanese military occupation in the Philippines. Following Manila's fall, Krueger aimed to eliminate the Shimbu and Shobu Groups to finalize the liberation of Luzon. Meanwhile, MacArthur deemed it crucial to establish a safe, direct shipping route through the central Philippines to support the creation of large air, naval, and logistical bases on Luzon. Consequently, he instructed the 6th Army to secure southern Luzon and the Bicol Peninsula while also ordering General Eichelberger’s 8th Army to seize the islands in the Visayan Passages and the northern part of Samar. To facilitate the southern Philippines Campaign, MacArthur reassigned the 40th and 41st Divisions, the 19th and 34th Regiments of the 24th Division, and the 503rd Parachute Regiment back to the 8th Army. Additionally, he designated the 37th Division to garrison Manila. With the 43rd Division sent south to replace the 40th at Clark Field, Krueger assigned the recently arrived 33rd Division, led by Major-General Percy Clarkson, to take control of the Damortis-Rosario sector. Meanwhile, as the 188th Glider Regiment cleared Ternate Island, Krueger also decided to deploy the 11th Airborne Division and the 158th Regiment to secure the northern shores of the Visayan Passages and open Batangas and Balayan Bays. However, this left only the 1st Cavalry Division and the 112th Cavalry Regiment available for operations against the Shimbu Group, leading Krueger to reluctantly redeploy the 6th Division south to reinforce the 14th Corps, leaving just the 25th, 32nd, and 33rd Divisions under the 1st Corps for operations in northern Luzon.

After making these adjustments, Krueger and Griswold began strategizing their offensive eastward against General Yokoyama’s Shimbu Group, which had recently received the Noguchi Detachment from the Bicol Peninsula. To ensure the security and recovery of the Manila Bay area, General Patrick’s 6th Division was tasked with first capturing Wawa Dam and its pipeline connections, followed by securing Ipo Dam and its related facilities, essential for meeting Manila's water needs. Meanwhile, General Hoffman’s 2nd Cavalry Brigade was assigned to secure the Antipolo-Tagig region. Between February 20 and 22, even before the fierce fighting in Manila began to ease, the 7th Cavalry crossed the Marikina River to take control of Taytay and then ventured into the Sierra Madre foothills. The 8th Cavalry followed suit, crossing the river to secure Tagig. On February 23, the 2nd Cavalry Brigade advanced east toward Antipolo, but General Noguchi effectively utilized artillery and conducted small-scale nightly infiltration attacks, successfully harassing and delaying the cavalrymen, who could only measure their progress in feet. Noguchi’s effective passive defense meant that by March 4, the 2nd Cavalry Brigade was still a mile and a half from Antipolo, having incurred heavy casualties during this frustrating advance. Among the wounded was General Mudge, who was temporarily replaced by Hoffman as commander of the 1st Cavalry Division. On February 22, the 6th Division also began crossing the Marikina River, with the 20th Regiment fording at Marikina town and the 63rd Regiment crossing at Montalban and San Mateo. Facing no resistance, the 20th Regiment advanced a mile into the steep, grassy hills northeast of Marikina, while the 63rd probed into the high ground east of San Mateo by the evening of February 23.

The troops initiated an assault on General Kobayashi’s primary defenses at Mounts Pacawagan and Mataba, but made minimal progress before the 1st Regiment arrived from Bataan on February 25. With this new reinforcement, Patrick launched a coordinated attack involving three regiments against Pacawagan and Mataba. However, by March 4, they had only secured a tenuous foothold on the northern crest of Pacawagan, as the efforts of the 1st and 20th Regiments were entirely unsuccessful.

 

Meanwhile, noticing an uptick in guerrilla activity in the Bontoc and Baguio areas, which indicated a potential major enemy offensive on Baguio, and considering the possibility of an airborne assault in the Cagayan Valley, General Yamashita began reorganizing his forces while preparing the defenses of the triangular redoubt in northern Luzon. He kept most of the 103rd Division stationed in the Aparri and Vigan sectors, assigned the 177th Independent Battalion to secure the naval air base at Tuguegarao, and started organizing eight provisional companies from the remnants of the 2nd Parachute Group at Echague. He tasked the 10th Division with defending the Salacsac-Balete Pass sector to the last man, gathered the remnants of the 2nd Tank Division at Dupax to reform as an understrength infantry division, and relocated the 105th Division to Bagabag, where it would be bolstered by the 10th Regiment. Additionally, he assigned these three divisions to Major-General Konuma Haruo’s self-sufficient Bambang Branch, transferred the 19th Division to the Bontoc area to combat the enemy guerrillas, tasked the Hayashi Detachment with holding San Fernando, began moving the worn-out 58th Independent Mixed Brigade north to defend Route 9, and ordered the fatigued 23rd Division to continue containing the enemy in the Rosario-Baguio sector.

General Swift’s 1st Corps, which had recently lost two divisions, was focusing its main efforts against Baguio. Clarkson’s 33rd Division was set to advance north along Route 11, while General Gill’s 32nd Division would move northwest through the Ambayabang, Agno, and Arodogat valleys from the south and southeast. Meanwhile, General Mullins’ 25th Division planned to launch a holding attack on the Bambang front. However, in mid-February, as Clarkson’s forces continued to pressure Japanese troops entrenched along the Hill 600-Hill 1500 ridgeline, they learned that General Sato's withdrawal to the north was already in progress to bolster the San Fernando front. Additionally, the 130th and 136th Regiments successfully cleared the last Japanese forces from the north-central part of the ridgeline by February 22, although they were unable to capture the Hill 600 complex. At the same time, the 32nd and 25th Divisions conducted extensive patrols in their areas, discovering that the Japanese were guarding every approach to the north as various units made contact with Japanese outposts. During this period, the Americans also identified the Baguio-Aritao supply road. Severing this link in the Japanese defensive network would provide the 1st Corps with a significant tactical advantage. Given that the Baguio end of the supply road was more heavily defended and that breaking through to Aritao would threaten the critical Bambang and Bagabag positions, Krueger and Swift decided that the 25th and 32nd Divisions would concentrate their efforts on the Bambang front, while the Baguio front would be maintained in a holding capacity.

Volckmann’s missions as assigned by 6th Army, which assumed control of USAFIP(NL) on January 13, were to gather intelligence, ambush Japanese patrols, seize or destroy Japanese supplies, disrupt Japanese lines of communication, and block Japanese routes of withdrawal into and exit from the Cagayan Valley. It was not, apparently, initially intended that Volckmann's force would engage in sustained efforts against major Japanese units, and there seems to have been little hope that Volckmann's, or any other guerrilla unit, would ever become effective combat organizations. The most help General MacArthur and Krueger probably expected was in the form of harassing raids, sabotage, and intelligence. But Volckmann--and other guerrilla leaders on Luzon as well--interpreted his missions as broadly as his strength and armament permitted. By the end of February USAFIP(NL) had cleared much of the west coast of Luzon north of San Fernando and also controlled the north coast west of Aparri. Volckmann had rendered Route 11 between Baguio and Tuguegarao and Route 4 from Libtong to Bagabag virtually impassable to the Japanese. Indeed, one of the main reasons that Yamashita moved the 19th Division north had been to regain control over the two vital highways so that supplies could continue moving into the final redoubt. While USAFIP(NL) did not possess sufficient strength to attack major Japanese concentrations or to hold out against large-scale punitive expeditions, it had diverted and pinned down Japanese forces that could undoubtedly have been used to better advantage elsewhere. It would appear that by mid-February USAFIP(NL) had accomplished far more than MacArthur or Krueger had either expected or hoped.

Meanwhile, the 121st Regiment secured the highway from Vigan south to Libtong, with Company L capturing Cervantes and pushing the 357th Independent Battalion into the Bessang Pass. Elements of the 121st then shifted their focus to San Fernando, which they attempted to attack unsuccessfully in late February and early March. Following Swift’s new strategies, the 33rd Division began patrolling the approaches to Baguio in the last week of February, successfully overrunning the last Japanese positions on Hill 600 and in the Arodogat Valley. Along Route 11, the 71st Regiment executed a successful fighting withdrawal, while American patrols along the coast occupied Agoo and advanced to Pugo with minimal resistance, only to encounter the first sections of the Tuba Trail defended by elements of the 64th Regiment. On the main front, the 25th Division commenced its advance to Puncan on February 21, while the 32nd Division began its push up the Villa Verde Trail toward Santa Fe. The 127th Regiment broke through the trail’s outpost line on February 24; the 35th Regiment advanced unopposed along Route 100, reaching Carranglan on February 26; the 161st Regiment targeted high ground overlooking Puncan from the west and successfully secured the trail junction on February 28, diverting the enemy’s attention; and the 27th Regiment pushed north along Route 5, facing fierce resistance while clearing the Lumboy area on February 27.

On Villa Verde, the 127th Regiment advanced to the Cabalisiaan River crossing by March 1, where they once again defeated the 10th Reconnaissance Regiment. After leaving one battalion to secure the crossing, the 127th continued their advance and encountered the weakened Japanese defenders on March 3. Recognizing the threat to the Salacsac Pass, Konuma promptly sent reinforcements to the 10th Reconnaissance Regiment and ordered General Iwanaka’s recently reorganized 2nd Tank Division to prepare for deployment to the Salacsac Pass, taking command of all troops along the Villa Verde Trail. While these reinforcements were en route, the 127th Regiment continued to assault the remaining positions of the 10th Reconnaissance Regiment, ultimately reaching the western entrance of Salacsac Pass on March 5. Meanwhile, to the south, a battalion from the 35th Regiment descended a rugged trail into Puncan from the northeast and secured the heights overlooking the damaged town on March 1. The next day, as patrols entered the deserted Puncan, the rest of the regiment cautiously advanced west along Route 100 from Carranglan, occupying Digdig without resistance on March 3. Over the following two days, organized resistance began to crumble throughout the Lumboy-Puncan area, with Mullins’ three regiments successfully connecting at Puncan and Digdig after the encirclement of a 1,250-man enemy force. Concerned about these developments, Konuma quickly decided to bolster the 10th Division with the Takachiho Unit and the majority of the 10th Regiment. Additionally, the 2nd Battalion of the 126th Regiment began its advance up the Ambayabang Valley on February 25, successfully reaching Lawican by March 5. In response to this new threat, Yamashita swiftly directed his reserve 16th Reconnaissance Regiment to secure the upper reaches of the Ambayabang.

Finally, to the south, the Americal and 24th Divisions were tasked with initiating operations to secure the Visayan Passages. Consequently, on February 19, the 1st Battalion of the 182nd Regiment landed on Capul Island and launched an assault on Biri Island the next day. After discovering other unoccupied islets near Samar, the battalion established a base at the northwestern tip of Samar, ultimately defeating the last organized resistance in that region by March 1. Meanwhile, elements of the 19th Regiment landed on Verde Island on February 23, managing to secure the island by March 3. The 1st Battalion of the 21st Regiment made an unopposed landing on Lubang Island on February 28, and the 1st Battalion of the 132nd Regiment successfully captured Ticao and Burias Islands on March 3. Additionally, on the morning of February 23, a task force comprising the 1st Battalion of the 188th Glider Regiment, the 1st Battalion of the 511th Parachute Regiment, a Provisional Reconnaissance Platoon from the 11th Airborne Division, several guerrilla groups led by Lieutenant-Colonel Honorio Guerrero, along with supporting artillery, tank destroyers, and amphibious tractors, executed a carefully coordinated rescue of 2,147 internees from an internment camp near Los Baños on Laguna de Bay. The 1st Battalion of the 188th Glider Regiment, commanded by Lieutenant-Colonel Robert Soule, launched a diversionary ground attack from the west, while the majority of the 1st Battalion of the 511th Parachute Regiment crossed Laguna de Bay using amphibious tractors. Company B of the 511th Parachute Regiment parachuted directly into the camp, and the Reconnaissance Platoon along with the guerrillas, who had already infiltrated the area, created chaos throughout the camp.

The task force eliminated the Japanese garrison of about 250 guards and managed to escape through enemy-held territory before the Fuji Force could mount a counterattack. The casualties were minimal: only 3 Americans and 2 Filipinos lost their lives, while 2 Americans and 4 Filipinos were injured. However, starting two nights after the raid, the 17th Regiment, along with Kempeitai police and Filipino Ganaps, began terror raids in the surrounding barrios, resulting in the deaths of up to 1,500 Filipino civilians over the next few nights. It was now time to leave the Philippines and return to New Guinea to support the ongoing Australian campaign in Aitape-Wewak. Previously, Brigadier Martin’s 19th Brigade had fought its way to Malin and Abau, while Colonel Buttrose’s 2/5th Battalion secured Perembil, Asiling, Samisai, and Maharingi. On January 12, Brigadier Moten directed the battalion to initiate a three-pronged offensive toward Luwaite, Bulamita, and Bombisima. The advance was rapid, as patrols encountered only small enemy groups, and all three objectives were successfully captured by the end of January. After the capture of Malin, the 2/8th Battalion and the 2/9th Commando Squadron patrolled the rugged terrain between Nimbum Creek and the upper Danmap for three weeks, facing some resistance on Long Ridge. Due to this pressure, General Aotsu’s force received additional reinforcements in the latter half of January before withdrawing to join the defenses of the 20th Division, while General Mano’s 41st Division retreated to Balif and Salata. Meanwhile, General Stevens had ordered Brigadier Roy King’s 16th Brigade to relieve the 19th at the Danmap, but catastrophic floods hindered the completion of this relief in the south before the month ended.

In the north, the 2/1st Battalion took over from the 2/11th Battalion on January 24 and began advancing patrols along Nambut Hill, where they faced significant resistance. Due to these patrols, the Australians launched a company attack on February 4, which the defenders easily repelled. Following a heavy air bombardment, the enemy stronghold was captured on February 7, and another company took McNeil’s Creek four days later. Meanwhile, the 2/3rd Battalion initiated an assault on Long Ridge, inflicting considerable casualties on the enemy at Cory's Spur. At this juncture, Stevens decided to sequentially capture But, Dagua, and Wewak, as well as Maprik in the mountains, and to push eastward. The 16th Brigade was the first to advance to Wank Creek and then to the Anumb River. King promptly sent the 2/1st Battalion to secure Nambut Creek while the 2/3rd Battalion moved to the Wolhuk Creek-Una Creek line. By February 18, the 2/1st Battalion had fully secured Nambut Hill, with one company advancing along the coast and pushing the Japanese across the creek the next day. By February 22, the area up to Balam Creek was occupied, and barges had delivered supplies at Wank Creek for four days. The following day, they reached the Anumb River and began patrolling toward Sowom while a sloop bombarded enemy positions along the coast. Finally, on February 28, the 2/2nd Battalion relieved the weary 2/1st Battalion and started preparing for operations against But. Simultaneously, the 2/3rd Battalion successfully established the Wolhuk Creek-Una Creek line and sent patrols northward to connect with both the 2/1st and 2/2nd Battalions.

In early February, the 2/5th Battalion launched an attack on Salata, Balif, and Balaga, sending three companies southward. Salata and Bombeta were captured on February 3, followed by Balif three days later, while Balaga remained successfully defended. The 2/6th Cavalry Commando Regiment was tasked with supporting Moten’s advance toward Maprik, prompting the 2/10th Commando Squadron to move to Ami. After the Australians secured the Balaga-Numango area on February 13, Buttrose dispatched two companies to capture Barangabandangi and Malahun, which fell by February 17. At this time, the 2/10th Commando Squadron had also advanced northeast of Ami to Walahuta, Kualigem, and Amahaur, resulting in several Japanese casualties. Meanwhile, the 2/7th Commando Squadron conducted patrols deep into the Atob River and the headwaters of the Screw River. The 2/5th Battalion was preparing for relief by the 2/7th Battalion but first needed to fend off a strong counterattack at Malahun on February 23. During the 2/5th's advance, most of the 40th Division withdrew south into a densely populated garden area bordered by the Nanu and Amuk Rivers. This southern flank could not be overlooked as the Australians moved toward Maprik, so Moten sent a company from the 2/6th Battalion to advance through M'Bras, Asanakor, Yubanakuor, and then east to the heavily fortified Sinahau villages, pushing the enemy toward Maprik for destruction. Additionally, a rumor was spread among the locals that the commandos would advance on Maprik via Ami, which successfully prompted the Japanese to reposition most of their forces to the north and northeast.

Meanwhile, by early March, the 2/7th Battalion had completed the relief of the 2/5th Battalion and successfully occupied Asanakor on March 7, followed by Inimbi on March 8, Yubanakuor on March 9, and Balangabadabil, Ilahop, and Armimin on March 10. To the north, the 2/2nd Battalion also finished its relief at the Anumb. Additionally, the 2/3rd Machine-Gun Battalion and the 2/9th Commando Squadron took over from the 2/3rd Battalion in the mountainous region. The latter began advancing towards Arohemi on March 4, where they encountered a strong Japanese force that resisted for three days. After a significant airstrike, the Australians managed to clear the area west of the Anumb River by March 9. Simultaneously, the 2/2nd Battalion pushed forward to Simbi Creek, successfully clearing the area and reaching the Ninahau River by March 12.

The battle for Manila is finally over. The capital of the Philippines came at a terrible cost for the Americans, Japanese and innocent Filipino civilians. It would be only a matter of time until the Americans moped up the Philippines and continued onwards to the Japanese home islands.

- 170 - Pacific War Podcast - Invasion of Iwo Jima - February 18 - 25 - , 1945

Last time we spoke about the liberation of Bataan and Corregidor. The Shimbu Group's commander launched a coordinated raid on northern Manila, aiming to weaken enemy defenses. Despite heavy casualties, the Allies captured key locations, including Nichols Field. Meanwhile, General Chase's 38th Division overcame strong Japanese defenses at ZigZag Pass, while General Hall's forces secured Bataan. Plans for an airborne assault on Corregidor were set for February 16, leveraging surprise against the outnumbered Japanese garrison. American forces launched the strategic attack on Corregidor, dropping paratroopers from the 503rd Regiment. Despite facing sporadic fire, they secured key positions. The following days saw intense skirmishes as the 3rd Battalion, 34th Regiment landed and established a foothold. Over eight days, they repelled numerous Japanese counterattacks, inflicting heavy casualties. By February 26, organized resistance crumbled, leading to the island's capture. Meanwhile, in Manila, American troops advanced, clearing buildings and securing the city, inching closer to victory in the Philippines.

A few weeks ago we spoke about Operation Detachment. Admirals Nimitz and Spruance were planning an invasion of Iwo Jima with General Schmidt’s 5th Amphibious Corps. During a thorough campaign of preliminary air and naval bombardment against the Volcano Islands, the 4th and 5th Marine Divisions, along with other Corps units, were loading at Hawaii between December 25 and January 25. Once training and loading were complete, Admiral Turner’s Task Force 51 and Admiral Hill’s Task Force 53 left Pearl Harbor on January 27, initially heading toward Saipan. By February 12, Admiral Spruance’s 5th Fleet had gathered in the Marianas and was prepared to sail for Iwo Jima. Additionally, Admiral Mitscher’s Task Force 58 had departed Ulithi to conduct a series of supporting air strikes over and around Tokyo, known as Operation Jamboree. Task Force 58 sortied from Ulithi 10 February and shaped a course eastward of the Marianas and Bonins. On the 12th, the air groups rehearsed with the 3rd Marine Division on Tinian. Two days later the task force fueled at sea from one of Admiral Beary's replenishment groups. Everything possible was done to guard against detection. Measures included radio deception, scouting by Pacific Fleet submarines to dispose of any picket vessels there might be en route, scouting by B-29s and Navy Liberators from the Marianas to clear the air. On the 15th a scouting line of five destroyers ranged ahead of the carriers, and antisubmarine air patrol was set up. At 1900 a high-speed run-in began towards launching positions, where the carriers arrived at dawn 16 February. Thanks to these precautions, and to thick weather most of the way, they arrived undetected.

General LeMay’s 21st Bomber Command, which was being reinforced by the 313th and 314th Bombardment Wings, would also assist Detachment with several strikes against Japan. Following some unremarkable high-altitude daytime missions in late January, 129 B-29s from the 73rd and 313th Bombardment Wings targeted Kobe on February 3, using a mix of incendiaries and fragmentation bombs. This attack caused significant damage to the urban area and local war production, resulting in the loss of 2 bombers and damage to 35 others. Subsequently, on February 10, a precision strike was launched against Ota’s Nakajima aircraft factory, with 84 out of 118 dispatched B-29s successfully bombing the site. However, only 14% of the bombs hit the target, leading to the loss of 12 bombers and damage to 29. Nearly one-third of the factory buildings sustained damage, primarily from the incendiaries combined with high-explosive bombs.

Five days later, LeMay dispatched 117 B-29 bombers to target Mitsubishi's engine works in Nagoya. However, an unexpected cold front resulted in only 33 bombers reaching the target area, yielding lackluster results. Meanwhile, after conducting some assault rehearsals, Spruance’s amphibious support forces and tractor groups set sail for Iwo Jima on February 14, followed two days later by Turner’s main assault convoy. At the same time, the reserve 3rd Marine Division continued loading at Guam, with its 21st Marines departing for Iwo Jima on February 16, followed by the main body of the division the next day. On the morning of February 16, Admiral Blandy’s Amphibious Support Force arrived off Iwo Jima and promptly commenced the final preliminary bombardment and minesweeping operations, although inclement weather hindered these efforts. However, the next day, Task Force 52 successfully carried out these missions; beach reconnaissance by UDTs faced heavy mortar fire, resulting in the sinking of one LCI gunboat, damage to eleven others, and casualties of 44 killed and 152 wounded. Despite this, the frogmen encountered no obstacles on the beaches and managed to create accurate maps of the approaches. Meanwhile, by February 16, Mitscher’s carriers had quietly moved to a position 60 miles off the coast of Honshu, launching extensive fighter sweeps against airfields in Tokyo Bay and bombing raids on aircraft frame and engine plants in the Tokyo area. 

About 100 Japanese fighters attacked Admiral Davison's planes as they crossed the coast and about 40 of them were shot down. American pilots found the Japanese on the whole reluctant to engage; Admiral Mitscher had correctly told his pilots, "He is probably more afraid of you than you are of him". In fact the IJAAF 10th Hiko Shidan immediately ordered an IJAAF night-fighter group and all “second-class” personnel to take cover, while all aircraft not intercepting were ordered to be dispersed, fuel tanks drained, and ammunition unloaded. In contrast, American pilots reported Tokyo antiaircraft fire “the most accurate and intense yet encountered.” By nightfall, Rear-Admiral Matthias Gardner’s night-flying carrier group conducted a sweep of night fighters to cover the enemy airfields at dusk. This operation was repeated the following morning, but poor weather ultimately forced the carriers to retreat toward Iwo Jima.

Despite this, significant damage was inflicted on aircraft frame and engine facilities, with 10 vessels sunk, including the unfinished escort carrier Yamashio Maru. A total of 531 aircraft were reported destroyed, at the expense of losing 88 planes and damaging two destroyers. On February 18, after the enemy battery camouflage had been obliterated during the previous two days of bombardment. This revealed batteries not previously known to exist, the island's defenses were for the first time properly revealed; and formidable they were indeed. Fortunately for the Americans, the support of UDTs with LCI gunboats had convinced General Kuribayashi that the main landing had started, and to repel it he unmasked batteries that would have caused very heavy casualties on D-day had they not been discovered two days before. This was the only serious mistake made by the Japanese general in his defensive tactics, which won the rueful admiration of his enemies.

Blandy opted to focus on the immediate area and flanks of the eastern beaches. Heavy ships moved closer to 2,500 yards to deliver concentrated direct fire on all targets. Consequently, bombardment ships provided continuous direct fire throughout the day, effectively dismantling enemy defenses. However, during the night, the Japanese launched a minor raid that caused significant damage to the destroyer minesweeper Gamble and the destroyer escort Blessman. At 06:00 on February 19, Turner’s main force arrived off Iwo Jima and began maneuvering into final positions. Simultaneously, Admiral Rodgers’ warships executed the last pre-landing bombardment, coordinated with air strikes from Mitscher’s carriers. Between 08:25 and 08:55, as the first wave crossed the line of departure and advanced toward the shore under the protective rocket fire of gunboats, shells fell heavily on Iwo Jima, marking the most intense pre-landing bombardment of World War II. At 08:57, as the leading armored amtracs approached their targets, naval gunfire shifted inland and to the flanks. The LVTs of the first wave touched down on Iwo Jima at 09:02 and began moving forward through the high terraces of soft black volcanic ash, engaging inland targets from the water to support subsequent landings. Three minutes later, the Marines of the 4th and 5th Divisions started landing side by side on the Green, Red, Yellow, and Blue beaches.

The assault infantry battalions of the Landing Force received assistance throughout D-Day from all the supporting arms available to the Amphibious Support Force. Carrier pilots of Task Force 58 and the escort carriers of Task Force 52 flew missions all day as airborne observers and spotters maintained constant vigilance over the target. Including pre-H-Hour strikes, 606 support aircraft flew 26 missions on February 19 and dropped 274500 pounds of bombs. These planes also fired 2254 rockets into the island defenses and dropped over a hundred napalm bombs. Air and naval gunfire liaison teams remained in communication with both air and sea supporting units through the hectic hours that followed the beach assault. Naval rifles from 5- to 16-inch caliber pounded enemy positions in response to Marine requests. Gunfire support vessels engaged enemy artillery that covered landing areas from high ground to the north, and concentrated on concealed Japanese mortars that shelled landing areas with deadly effect.

The units quickly reorganized and began their advance inland, facing only light resistance, although their progress was hampered by the sandy terrain. General Kuribayashi’s forces, however, had been waiting in well-fortified underground positions as planned, emerging only after the bombardment ceased to unleash a barrage of machine-gun, rifle, and mortar fire on the advancing troops. As the initial waves of Marines struggled to advance, congestion along the shore became increasingly critical, while the full force of the Japanese defenders was unleashed shortly after 10:00. By 10:30, elements from all eight assault battalions had landed on the island, successfully bringing ashore about 6,000 men and bulldozers that were clearing paths for tank deployment. On the far left flank, Colonel Harry Liversedge’s 28th Marines, having landed on Green Beach, initiated a rapid advance across the half-mile isthmus below Mount Suribachi to isolate this crucial position. The attack unfolded in such a way that some units were delayed while others managed to break through and continue westward despite suffering heavy casualties, ultimately crossing the island while the bypassed enemy was being dealt with. By midday, the reserve 3rd Battalion and tanks landed under heavy fire to join the afternoon assault on Suribachi, but intense enemy fire hindered their progress to the assault positions. Consequently, the 2nd Battalion launched an attack on its own, gaining only 150 yards before retreating to regroup with the 3rd Battalion for the night.

At the same time, Colonel Thomas Wornham’s 27th Marines had landed on the Red Beaches, making swift progress inland despite increasing casualties and bypassing numerous enemy positions. By 11:30, Company A was moving across the southern end of Airfield No. 1, establishing a presence along the western edge while other units continued to advance past the airfield. The 1st Battalion launched an attack on the airfield with tank support but faced strong enemy resistance, resulting in minimal gains. Meanwhile, the 2nd Battalion pushed westward and reached the cliffs overlooking the western coast. Additionally, the reserve 3rd Battalion landed and began clearing bypassed positions, while the artillery units from the 13th Marines and General Rockey’s reserve 26th Marines also arrived in the afternoon as the 27th and 28th Marines solidified their positions. By nightfall, although the 5th Marine Division was still a considerable distance from the O-1 Line, it had established a firm foothold on the island, with Mount Suribachi isolated and portions of the airfield under their control. To the east, General Cates' 4th Marine Division also landed successfully, with Colonel Walter Wensinger’s 23rd Marines coming ashore at the Yellow Beaches and Colonel John Lanigan’s 25th Marines landing on Blue Beach 1 and the southern part of Blue Beach 2. The two regiments began their advance inland, hindered by intense enemy fire but managing to gain between 400 and 600 yards by midday. As tanks were being deployed, the 3rd Battalion of the 25th Marines moved to the right to clear the remaining area of Beach Blue 2 and encircle the threatening quarry zone.

At this stage, as the assault battalions continued their advance, Wensinger and Lanigan deployed their reserve battalions to cover the gaps in their attack lines. With the support of tanks that had finally reached the front, the 23rd Marines advanced towards Airfield No. 1 and successfully captured its outskirts. Meanwhile, the 25th Marines initiated a coordinated assault, with the 3rd Battalion advancing about 200 yards along the beach to secure the problematic quarry, while the other two battalions moved north to seize the high ground to the northwest of the quarry. By the end of the day, Cates had also landed half of the artillery from the 14th Marines, along with his reserve 24th Marines, which began to relieve some of the frontline units from both assault regiments. Although the penetration by the 4th Marine Division was not as extensive as intended, by nightfall, the front lines included the eastern edge of the airfield and extended sufficiently inland from the Blue Beaches to ensure the beachhead could be held successfully. The Marines, forced to advance across open terrain while enduring intense fire from well-concealed positions that were difficult to target, fell significantly short of the O-1 objective. Nonetheless, by the end of the day, six Marine regiments, an equal number of artillery battalions, and two tank battalions had landed and were positioned to defend the narrow beachhead against a potential night counterattack. 

Throughout this first day, the situation on the beaches prevented landing of any but the highest priority "hot cargo." This consisted of ammunition, rations, water, and signal equipment brought to the beach in LCVPs and LCMs. Shore party teams, working under extremely adverse conditions without sufficient trucks and other heavy equipment, could do little more than stack the supplies on the beach above the high water mark. LVTs and weasels made trips from the beach dumps inland carrying these supplies to the troops and returned bearing wounded men. The busy amtracs also made nonstop trips from LSTs, ferrying critically needed items direct to Marines on the front lines. Most of the transports and other vessels of the task force retired from the island at nightfall, but some command ships, preloaded LSTs, and hospital LSTs remained behind. Emergency items, especially 81mm mortar ammunition, were brought in during the night, but actually very little unloading was accomplished and many of the wounded spent this night on the beach because they could not be evacuated. Some progress was made cutting exits through the terrace and clearing mines, but enemy fire and the shortage of equipment limited this activity. Despite this, the Japanese did not launch any large-scale assaults, although their mortars and artillery relentlessly bombarded Marine lines along the front throughout the night. Consequently, Allied casualties on this first day totaled 548 killed and 1,755 wounded.

On February 20, the goal was for the 28th Marines to take Mount Suribachi while other units advanced north to capture the two airfields. Initially, in the south, after a coordinated air and naval bombardment, Liversedge launched another assault on the volcano but managed to gain only 75 yards by midday. During the forenoon, Marines gained only 50-70 yards. Aircraft and ships pounded Japanese positions and the 3d Battalion, 13th Marines fired mission after mission, but stiff enemy resistance continued, particularly from well-camouflaged pillboxes hidden in the brush to the front of the Marine lines. These emplacements, too close to friendly troops to be engaged by heavy support weapons, could only be silenced by coordinated attacks of assault demolition teams using flamethrowers and explosive charges.

Tanks then moved in to provide support, allowing the attack to progress from pillbox to pillbox; however, by the end of the day, the Marines had only advanced 200 difficult yards. Meanwhile, Schmidt’s other regiments initiated a coordinated offensive to the north following extensive artillery, naval gunfire, and air support. Despite facing heavy resistance, the 23rd Marines successfully overran most of Airfield No. 1 by noon. Wensinger continued to push his units in the afternoon, but progress was limited as tanks were hindered by minefields and rough terrain. Wornham’s 27th Marines pressed their attack on the left flank, overcoming enemy mortar and artillery fire to gain about 800 yards along the coast. In contrast, Lanigan’s 25th Marines, affected by friendly fire, made only minimal advances against enemy crossfire from concealed positions. At 1600, friendly planes misdirected their fire to the 25th Marine’s area, adding terror to the situation. An air strike consisting of .50-caliber machine-gun strafing, rockets, and bombs fell on troops of Company B of the 24th Marines, which was positioned on top of the quarry some 400 yards inland from the eastern shore. This strike was made without a preliminary "dry-run", and despite the fact that yellow front line panels were displayed prior to and during the aerial attack. The 1st Battalion, 24th Marines suffered five killed and six wounded as a result of this misguided effort. Shortly after the planes left the area, this battalion reported that friendly artillery and naval gunfire was being registered on its lines. Due to the slow progress, Schmidt attempted to land his reserve 21st Marines, but high seas and congested beaches ultimately thwarted these efforts. Nevertheless, the remaining 14th Marines were landed, albeit with significant casualties, and elements of the corps artillery began to come ashore. During the night, there were no counterattacks on Mount Suribachi, but the 4th and 5th Marine Divisions had to fend off some small counterattacks on their front lines.

On February 21, following a strike involving 40 aircraft, Liversedge’s 28th Marines launched another assault on the volcano. The 1st Battalion on the right swiftly advanced along the west beach to the base of Suribachi, while the 3rd Battalion in the center pushed nearly to the foot of the mountain despite facing heavy resistance. Meanwhile, the 2nd Battalion on the left moved cautiously along the east beach toward the volcano's base, with Company F heading toward Tobiishi Point. At the same time, other regiments continued their offensive towards O-1 after a bombardment from air, artillery, rockets, and naval gunfire. Rockey’s units made significant progress, advancing over 1,000 yards, while the 23rd Marines achieved similar gains on the left flank, where slightly sheltered areas allowed for local and limited encirclement, but only advanced 100 yards in the right and center. The 25th Marines maintained steady pressure against the strong enemy defenses, gaining between 50 and 300 yards across the front. Colonel Hartnoll Withers’ 21st Marines successfully landed this time; due to heavy casualties in the center, they were assigned to relieve the exhausted 23rd Marines. By nightfall, the Marines had to fend off several local counterattacks and infiltration attempts. 

During the night, 50 kamikaze planes targeted Blandy’s Task Force 52. They were picked up by the radar of the USS Saratoga, a veteran carrier of the Pacific War, and six fighters were sent to intercept. They shot down two Zeros but the remaining Zeros plowed on through the low lying cloud, two of them trailing smoke, and slammed into the side of the carrier turning the hangers into an inferno. Another solitary attacker smashed into the flight deck leaving a gaping hole 100 yards from the bow. Damage control teams worked wonders and within one hour the fires were under control and the Saratoga was able to recover a few of her planes. Another aircraft, a "Betty" twin engined bomber, tore into the escort carrier USS Bismarck Sea. The decks were full of aircraft and the ensuing explosion caused uncontrollable fires. Abandon ship was sounded and 800 men went over the side. Within a few minutes a huge explosion ripped off the entire stern of the carrier and she rolled 38 over and sank. Three other ships were also damaged: the escort carrier USS Lunga Point was showered with flaming debris as four aircraft were blasted out of the sky; the minesweeper Keokuk was damaged when a "Jill" dive bomber hit her deck; and LST 477 loaded with Sherman tanks received a glancing blow. The Saratoga, with destroyer escort, returned to Pearl Harbor, but by the time the damage was repaired the war was over. The kamikazes had done their work well: 358 men killed, one carrier sunk, and another severely damaged. It was a grim preview of the mayhem they would later cause during the invasion of Okinawa in April.

On February 22, amidst a dreary cold rain, Liversedge renewed his assault on Suribachi, where only half of the original garrison remained to oppose the Marine advance. There was no let-up in the weather on Wednesday as Marines of the 28th Regiment, drenched to the skin and bent by the wind, prepared to renew the attack on Suribachi. Fresh supplies of ammunition had been brought to the front during the night, but the Shermans were mired in mud and the Navy declined to supply air support in the appalling weather. It was to be up to the foot soldier with rifle, flamethrower, grenade, and demolition charge to win the day. Colonel Atsuchi still had 800-900 men left and they had no intention of allowing the Americans an easy victory. Major Youamata announced: "We are surrounded by enemy craft of all sizes, shapes and descriptions, enemy shells have smashed at our installations and defenses, their planes bomb and strafe yet we remain strong and defiant. The Americans are beginning to climb the first terraces towards our defenses. Now they shall taste our steel and lead."

Throughout the day, the 28th Marines engaged Japanese positions on the lower slopes of the mountain, with the 3rd Battalion making the final push to the base of Suribachi while the other two battalions cleared the coastline to completely encircle the volcano. Simultaneously, Schmidt’s northern sweep continued, with the 21st Marines replacing Wensinger’s troops, and Colonel Chester Graham’s 26th Marines taking over on the 5th Division front. The 26th Marines advanced approximately 400 yards in the center but ultimately had to withdraw as the flanking units could not progress; the 21st Marines began their assault on the formidable defenses of Colonel Ikeda’s 145th Regiment in front of Airfield No. 2, managing to advance only about 250 yards on the right; and the 25th Marines were unable to launch an attack on the left due to Withers’ lack of significant gains and had to fend off several local Japanese counterattacks. Marine "Howlin' Mad" Smith aboard the USS Auburn was counting the cost. Three days of battle and the Regimental Returns listed 2,517 casualties for the 4th Division and 2,057 for the 5th: 4,574 dead and wounded and the O-1 line had just been reached. Little did he know that as his Marines approached the hills, ravines, canyons, gullies, and cliffs of the north the worst was yet to come. Additionally, as the 4th Division remained stalled, Cates ordered Colonel Walter Jordan’s 24th Marines to relieve the weary troops of Lanigan on the right. During the night, most of Task Force 58 departed the area for a second air strike against Tokyo, which significantly limited the availability of aircraft for direct support of ground forces on Iwo Jima.

On February 23, the 28th Marines under Liversedge launched their final assault on Suribachi. The 2nd Battalion was tasked with scaling the volcano's heights, while the 1st Battalion advanced south around the mountain's western side. To their surprise, they encountered no enemy fire, and small patrols reached the crater's edge by 09:40. 1st Lieutenant Harold G. Schrier, executive officer of Company E, and a 40-man detachment set out to follow the patrols and occupy the highest point of land on Iwo Jima. The number of live Japanese lurking in caves along this north face was unknown, so flankers were sent out to guard against ambush as Schrier's men clawed their way warily upward. Still there was a mysterious lack of enemy activity, and the only Japanese encountered were the harmless dead. Positions along the rim of the crater were reached at about 10:15, and as Marines scrambled over the lip, the tenseness was eased by action. A small defending force challenged the patrol and a short, hot fight developed. Even while this skirmish was in progress, some of the men located a length of Japanese iron pipe, secured a small American flag to one end, and raised the Stars and Stripes at 10:20. It was an inspiring sight for thousands of Americans on Iwo as the flag waved bravely from the summit. Shortly after the mounting of this flag that measured only 54 inches by 28 inches, an unidentified Marine went aboard LST 779, beached near the base of the volcano, to obtain a larger set of colors. As this second and larger (8 feet by 4 feet 8 inches) flag was being carried up the slopes of Suribachi, photographer Joe Rosenthal, who covered the Iwo operation for the Associated Press, noticed it and instantly started in close pursuit. His efforts that morning resulted in the now famous picture of the second flag raising.

Also since it's one of my favorite movies, I wanted to add this passage from the book “Flags of our Fathers” by James Bradley

The Secretary of the Navy, James Forrestal, had decided the previous night that he wanted to go ashore and witness the final stage of the fight for the mountain. Now, under a stern commitment to take orders from General Holland "Howlin' Mad" Smith, the secretary was churning ashore in the company of the blunt, earthy general. Their boat touched the beach just after the flag went up, and the mood among the high command turned jubilant. Gazing upward, at the red, white, and blue speck, Forrestal remarked to Smith: "Holland, the raising of that flag on Suribachi means a Marine Corps for the next five hundred years".

Forrestal was so taken with fervor of the moment that he decided he wanted the Second Battalion's flag flying on Mt. Suribachi as a souvenir. The news of this wish did not sit well with 2nd Battalion Commander Chandler Johnson, whose temperament was every bit as fiery as Howlin Mad's. "To hell with that!" the colonel spat when the message reached him. The flag belonged to the battalion, as far as Johnson was concerned. He decided to secure it as soon as possible, and dispatched his assistant operations officer, Lieutenant Ted Tuttle, to the beach to obtain a replacement flag. As an afterthought, Johnson called after Tuttle: "And make it a bigger one."

Following this, the 28th Marines conducted mopping-up operations to eliminate remaining enemy positions and seal off caves at the base of Suribachi. All accessible outer and inner slopes were covered as the Marines annihilated enemy snipers and blasted shut the many cave entrances, sealing in an uncounted number of Japanese. Much observation equipment was found, emphasizing the fact that this had been an excellent point of vantage from which hostile observers directed murderous fire against the entire beachhead. Marine artillerymen, ready and eager to seize this advantage, hastened to move flash-ranging equipment into position.

By nightfall, approximately 122 Japanese soldiers were killed while attempting to infiltrate American lines. Over the five-day period, the 28th Marines suffered 895 casualties, while nearly 2,000 Japanese were either killed or trapped in over 1,000 caves in the area. Kuribayashi had not anticipated the loss of this strategically significant location so early in the battle, and the survivors who managed to breach American lines faced severe reprimands upon their return to the north. For the remainder of the month, the 28th Marines focused on clearing out stubborn Japanese forces, reorganizing, and reequipping. Meanwhile, fighting in the north persisted as the three assault regiments advanced toward the O-2 Line. The 26th and 21st Marines faced heavy fire and struggled to make progress, while the 24th Marines advanced along their entire front, gaining up to 300 yards in some areas. On this day, the situation on the beach steadily improved as clearance efforts, construction of exits, and unloading continued, facilitating the arrival of essential ammunition and an additional 25 tanks.

On February 24, following extensive air, naval, and artillery preparations, the offensive resumed. However, the initial failure of tanks to join the assault due to minefields and heavy anti-tank fire forced the Marines to advance slowly under intense fire from various sources. In the center, the 3rd Battalion, 21st Marines advanced 800 yards, reaching the north side of the east-west runway of Airfield No. 2, while the 2nd Battalion gradually moved northward around the end of the runway by noon. In the afternoon, as tank support began to arrive, Withers’ 3rd Battalion captured the hill north of the airstrip after a fierce hand-to-hand battle. Simultaneously, his 2nd Battalion coordinated with the 26th Marines to seize the elevation beyond the airfield. Graham’s troops easily secured the ground in front but had to pause their advance when they found themselves about 400 yards ahead of the 21st Marines. On the right flank, the 24th Marines initially made significant progress alongside Withers’ men toward the airfield but were ultimately halted by the strong defenses on Charlie-Dog Ridge. 

Running along the southeast edge of the east-west runway of Airfield Number 2 was a ridge known only as "Charlie-Dog Ridge." In prolongation of this ridge, on a lower level to the southeast, was a semicircular rise of ground that formed the "Amphitheater." In this area, Japanese engineers had constructed some of the most formidable defenses on the island. From the south, the approach traversed bare flat ground swept by guns on the ridge. To the east, the route led across a weird series of volcanic outcroppings and draws. It was against these positions that the 24th Marines moved out on D-plus-5. Assault squads then had to methodically clear the ridge, moving from one strongpoint to another, using fire and explosives until Charlie-Dog was secured. While the overall gains for the day were notable by Iwo Jima standards, the casualty figures were also high, with the Marines suffering 1,034 killed and 3,741 wounded during the five-day push to the second airfield. Additionally, the remainder of General Erskine’s 3rd Marine Division began landing that day to officially take control of the central area.

On February 25, a decision was made to hold back the 26th Marines to allow the 3rd Division to align with them. After another intense bombardment, Colonel Howard Kenyon's 9th Marines advanced through the 21st to continue the assault, but the two-battalion attack only managed to gain a meager 100 yards against Ikeda's determined defenders. Kenyon then deployed his reserve 3rd Battalion in the center, but it also failed to break through. To the east, the 23rd and 24th Marines launched simultaneous attacks, but only the 23rd made significant progress, overrunning the eastern end of the strip and establishing a foothold on the high ground to the north. Meanwhile, in the morning, Mitscher's carriers conducted a second strike on Tokyo.

The Japanese sighted 600 US carrier aircraft on February 25, but Rear Admiral “Ted” Sherman reported, “The enemy opposition was only halfhearted and Japanese planes which were not shot down seemed glad to withdraw from the scene … as swiftly and unceremoniously as possible. Even here, over their own capital, the enemy were notably inferior to our naval aviators in aggressiveness, tactics, and determination.” TF-58 aircraft hit the Ota and Koizumi aircraft plants, but increasingly snowy, stormy weather meant Mitscher canceled further Tokyo strikes at 1215hrs. Spruance and Mitscher decided to hit Nagoya instead. En route to Nagoya that night destroyers USS Hazelwood and Murray sank three small Japanese craft. Eventually Mitscher realized TF-58 would not reach launching position on time, and at 0530hrs Spruance and Mitscher canceled the Nagoya strikes and headed south to refuel. TF-58 claimed 47 Japanese planes shot down and 111 destroyed on the ground for a total of 158 Japanese planes destroyed on February 25. Two hangars, one radar station, and two trains were destroyed. About 75 percent of the Ota engine plant’s buildings were destroyed and an additional 15 percent heavily damaged. The Koizuma plant had also been heavily hit, and five coastal vessels and several smaller craft sunk, with another 14 vessels damaged. Total US losses were nine aircraft to antiaircraft fire and four to operational causes; four pilots were lost.. After TF-58 aircraft had plastered the Nakajima Ota airframe plant with 45 tons of bombs, February 25 photoreconnaissance revealed Ota to be 60 percent destroyed and 30 percent heavily damaged, although half of this was believed due to B-29s. After the photos TF-58 aircraft dropped another 13 tons on the plant. The Nakajima Koizuma plant was attacked on February 25 with 35 to 40 tons of bombs, with hits concentrated in the center of the plant. Reconnaissance showed 20 percent of the Koizuma roof damaged. The Hitachi–Tachikawa aircraft engine plant was attacked by one Task Group strike, with US airmen reporting “excellent results.” Photographs showed many bomb hits, but smoke made precise damage assessments difficult. Slight damage was also inflicted on the Tachikawa airframe plant. TF-58 planes struck the B-29s’ nemesis, the Musashino-Tama aircraft engine plant, with 40 tons of bombs in the center of the Tama complex. 

On that day, LeMay also dispatched 231 B-29s to attack Tokyo with incendiaries, with 172 successfully dropping 453.7 tons of bombs, incinerating a square mile of the city. This operation served as the "conclusive" test of the incendiary bombs that the 20th Air Force had requested, with valuable lessons to be learned for future use. The next day, the 26th Marines resumed their attack despite the high ground on the left remaining unclaimed, successfully advancing over 300 yards in the right and center. In the center, the 9th Marines continued their assault with the 1st and 2nd Battalions side by side, but they made no notable gains.

On the right flank, the 23rd Marines launched another assault towards Hill 382, facing heavy resistance and managing to advance only about 200 yards. Concurrently, Lanigan’s 25th Marines moved through the battered 24th Marines, achieving an advance of approximately 100 yards before encountering intense machine-gun fire from the Amphitheater and Turkey Knob. On February 27, Wonrham’s 27th Marines took over from the exhausted 26th and continued to push northward despite rising casualties, successfully overrunning several strongpoints and gaining about 500 yards across the front. In the center, the 9th Marines finally breached the enemy's main defenses towards Hill 199-O and captured Hill Peter, securing Airfield No. 2. Meanwhile, on the right, the 4th Division pressed on against the heavily fortified Japanese positions at the Meatgrinder, advancing only 150 to 200 yards on each flank while struggling to make headway against the Amphitheater and Turkey Knob. In the final attack of the month, the 27th Marines advanced towards Hill 362A, reaching its base but were forced to retreat nearly 100 yards due to Japanese counterattacks and loss of communication. In the center, Withers’ 21st Marines moved past the 9th Marines and rapidly advanced north of Airfield No. 2, making significant progress on the right as they swept through Motoyama village and captured the high ground overlooking Airfield No. 3. To the east, Cates continued to send troops into the Meatgrinder, with the 23rd Marines gaining over 200 yards and launching an attack on Hill 382, while the 25th Marines struggled to make any headway against the Amphitheater and Turkey Knob, achieving only minor gains along the coast.

And thus we have begun one of the most brutal battles of WW2, let alone the Pacific War. It was a controversial decision to invade Iwo Jima and the Americans could never have predicted how the Japanese would change their tactics to turn the entire ordeal into one giant meat grinder.

- 169 - Pacific War Podcast - Liberation of Bataan and Corregidor - February 11 - 18 - , 1945

Last time we spoke about the battle of Manila. In early February, General Iwanaka's 2nd Tank Division faced encirclement as American forces advanced. General Griswold's 14th Corps captured Clark Field, while the 8th Cavalry liberated 4,000 internees at Santo Tomas University. Amid fierce fighting, Japanese defenses crumbled, and by February 9, American troops secured key districts in Manila. Despite heavy resistance, they pressed on, clearing areas and establishing a foothold across the Pasig River. In the wake of Pearl Ridge's capture, Australian brigades advanced through Bougainville, engaging Japanese forces along the Jaba and Tavera rivers. Brigadier Monaghan's troops secured strategic positions, while the 2/8th Commandos aided local guerrillas. In January, significant battles unfolded at Tsimba Ridge, where fierce resistance led to an encirclement of Japanese troops. Meanwhile, in Burma, Allied forces executed deceptive maneuvers and launched offensives, as General Aung San’s Burma National Army prepared to switch sides, signaling a shift in the war's momentum.

As we previously noted, General Griswold had three divisions stationed in Manila, which had achieved significant advancements by February 10. Estimating the strength of the Americans in the Manila area at little more than a regiment, General Yokoyama apparently felt that he had a good opportunity to cut off and isolate the Allied force. Conversely, he was also interested in getting the Manila Naval Defense Force out of the city quickly, either by opening a line of retreat or by having Iwabuchi co-ordinate a breakthrough effort with a Shimbu Group counterattack, scheduled for the night of February 16. Not knowing how far the situation in Manila had deteriorated--communications were faulty and Admiral Iwabuchi had supplied Yokoyama with little information--Yokoyama at first directed the Manila Naval Defense Force to hold fast. The question of a general withdrawal, he told Iwabuchi, would be held in abeyance pending the outcome of the counterattack. There is no indication that the Shimbu Group commander intended to reinforce or retake Manila. Rather, his primary interest was to gain time for the Shimbu Group to strengthen its defenses north and northeast of the city and to move more supplies out of the city to its mountain strongholds, simultaneously creating a good opportunity for the Manila Naval Defense Force to withdraw intact.

However, the commander of the Shimbu Group was simultaneously orchestrating a large-scale, coordinated raid on northern Manila, intending to weaken the enemy's offensive capability by targeting their vulnerable eastern flank before they could solidify their positions. Therefore, on the night of February 16, the majority of the 31st Regiment was set to assault Caloocan Airfield, while three provisional battalions of the Kobayashi Force would attack Quezon, Banlat Airfield, and the surrounding areas of Rosario. This meant that Iwabuchi’s forces would need to withstand the unyielding American assaults for another week before receiving support. Meanwhile, Griswold was strategizing to cut off the last remaining routes for withdrawal and reinforcement available to Iwabuchi. To achieve this, the 5th and 8th Cavalry Regiments were tasked with advancing southwest toward Manila Bay to make contact with the 11th Airborne Division, effectively encircling the city. Thus, Griswold continued his offensive on February 11, with Company E of the 129th Regiment successfully clearing Provisor Island without resistance and further establishing a presence on the mainland, west across Estero Provisor. Other elements of the 37th Division were gradually advancing across the Estero de Paco despite heavy enemy fire, while the 5th Cavalry made limited progress at Nielson Field. The 8th Cavalry pushed nearly to the Estero de Paco along the division boundary against scattered opposition, the 511th Parachute Regiment advanced north toward Libertad Avenue, and the 187th Glider Regiment secured the southeast corner and southern runway of Nichols Field.

The next day, to complete the encirclement of Manila, the 5th Cavalry swiftly advanced across Nielson Field, facing sporadic rifle fire, and successfully connected with the 511th at Libertad Avenue before reaching the shores of Manila Bay. Simultaneously, the 12th Cavalry Regiment relieved the 8th and rapidly moved westward to establish contact with the 5th at Villarruel Street. Further south, following intense artillery and air bombardment, the 187th and 188th Glider Regiments finally breached the Japanese defenses at Nichols Field. The attack was preceded by artillery and mortar concentrations and by an air strike executed by Marine Corps SBD's from the Lingayen Gulf fields, support that succeeded in knocking out many Japanese artillery positions. The 2d Battalion, 187th Infantry, attacked generally east from the northwest corner of the field; the 188th Infantry and the 1st Battalion, 187th Infantry, drove in from the south and southeast. By dusk the two regiments had cleared most of the field and finished mopping up the next day. The field was, however, by no means ready to receive Allied Air Force planes. Runways and taxiways were heavily mined, the runways were pitted by air and artillery bombardments, and the field was still subjected to intermittent artillery and mortar fire from the Fort McKinley area. With the seizure of Nichols Field, the 11th Airborne Division substantially completed its share in the battle for Manila. Since its landing at Nasugbu the division had suffered over 900 casualties. Of this number the 511th Infantry lost approximately 70 men killed and 240 wounded; the 187th and 188th Infantry Regiments had together lost about 100 men killed and 510 wounded, the vast majority in the action at Nichols Field. The division and its air and artillery support had killed perhaps 3,000 Japanese in the metropolitan area, destroying the 3d Naval Battalion and isolating the Abe Battalion. From then on the division's activities in the Manila area would be directed toward securing the Cavite region, destroying the Abe Battalion, and, in co-operation with the 1st Cavalry Division, assuring the severance of the Manila Naval Defense Force's routes of escape and reinforcement by clearing Fort McKinley and environs. 

Meanwhile, at ZigZag Pass, General Chase’s 38th Division had begun to make headway against the strong defenses of the Nagayoshi Detachment, with the 152nd and 149th Regiments set to launch a coordinated attack from the east and west on February 12. It wasn't until the afternoon of February 13 that the 149th and 152nd made their first brief contact from their respective sides of ZigZag. The 149th then captured the last organized Japanese stronghold on February 14, and the following day both regiments completed their mopping-up operations. Nearly 2,400 Japanese soldiers were killed at the pass during this battle, though about 300 men under Colonel Nagayoshi managed to escape south into Bataan. The 38th Division and the 34th Regiment, in turn, suffered around 1,400 casualties, including 250 killed. Meanwhile, General Brush’s 40th Division continued its offensive against the Kembu Group.

By February 12, the 185th Regiment had successfully secured Snake Hill North with minimal resistance, while also capturing Hills 810 and 1000. Meanwhile, the 160th Regiment made significant advances against Snake Hill West and Scattered Trees Ridge. The 108th Regiment, after neutralizing the Japanese strongholds on the hill, began attacking the remnants of the Eguchi and Yanagimoto Detachments at Hill 7. On February 15, the 185th captured Hill 1500, coinciding with the 160th clearing Snake Hill West and preparing to advance toward Object Hill. The next day, Hill 7 fell to the 108th, while the 160th reached the summit of Object Hill and broke through Scattered Trees Ridge. By February 20, the 160th had cleared the rest of Object Hill and established a foothold on Sacobia Ridge. Whatever the costs, the 40th Division's advances to February 20 marked the end of the Kembu Group as a threat to 6th Army and 14th Corps. Clark Field, Route 3, and the army and corps right were now secure beyond all shadow of doubt. The Kembu Group had defended its ground well since January 24, when 14th Corps had first gained contact, and had inflicted nearly 1500 casualties upon 14th Corps units--roughly 285 men killed and 1180 wounded--but had itself lost around 10000 men killed. The 20000 troops General Tsukada still commanded were hardly in good shape. Supplies of all kinds were dwindling rapidly, morale was cracking, and centralized control was breaking down. The only defenses still intact were those held by the naval 13th and 17th Combat Sectors, and those had been heavily damaged by air and artillery bombardments. Troops of the 6th Army would continue to fight the Kembu Group, but after February 20 operations in the Kembu area were essentially mop-ups. 11th Corps, not 14th, would be in charge of the final mop-up operations in the Kembu area.

Under General Hall’s leadership, the 40th Division resumed the mop-up operation on February 23, but was replaced by elements of the 43rd Division just five days later. In the following ten days, this division would ultimately eliminate General Tsukada’s last defensive position, pushing the Kembu Group further into the Zambales Range. Back in Manila, on February 13, chaos erupted as Iwabuchi’s forces prepared for their final stand in the Filipino capital. After February 12th the 14th Corps troops found themselves in a steady war of attrition. Street-to-street, building-to-building, and room-to-room fighting characterized each day's activity. Progress was sometimes measured only in feet; many days saw no progress at all. The fighting became really "dirty." The Japanese, looking forward only to death, started committing all sorts of excesses, both against the city itself and against Filipinos unlucky enough to remain under Japanese control. As time went on, Japanese command disintegrated. Then, viciousness became uncontrolled and uncontrollable; horror mounted upon horror. The men of the 37th Division and the 1st Cavalry Division witnessed the rape, sack, pillage, and destruction of a large part of Manila and became reluctant parties to much of the destruction. Although the 14th Corps placed heavy dependence upon artillery, tank, tank destroyer, mortar, and bazooka fire for all advances, cleaning out individual buildings ultimately fell to individual riflemen. To accomplish this work, the infantry brought to fruition a system initiated north of the Pasig River. Small units worked their way from one building to the next, usually trying to secure the roof and top floor first, often by coming through the upper floors of an adjoining structure. Using stairways as axes of advance, lines of supply, and routes of evacuation, troops then began working their way down through the building. For the most part, squads broke up into small assault teams, one holding entrances and perhaps the ground floor--when that was where entrance had been gained--while the other fought through the building. In many cases, where the Japanese blocked stairways and corridors, the American troops found it necessary to chop or blow holes through walls and floors. Under such circumstances, hand grenades, flame throwers, and demolitions usually proved requisites to progress. In response to the encirclement of Manila, Yokoyama concluded that the situation in the city was irreparable and ordered Iwabuchi to relocate to Fort McKinley and begin withdrawing his troops immediately, without waiting for the Shimbu Group's counterattack. However, Iwabuchi did not receive this order until two days later, by which time he and his troops were determined to fight to the death, taking as many enemies with them as possible.

The 129th Regiment made an unsuccessful attempt to assault the New Police Station and the Manila Club. Meanwhile, the 148th Regiment reached Taft Avenue but could not launch an attack on the Philippine General Hospital and the University of the Philippines. The 5th and 12th Cavalry Regiments turned north, taking two days to fight through the Pasay suburb to Vito Cruz Street. On February 14, although the 148th Regiment struggled to make any headway against Iwabuchi’s strong defenses, the 129th, supported by tanks, managed to break through to the Manila Club and the New Police Station. However, the Japanese quickly regrouped at the latter location and began throwing hand grenades from the second floor, forcing the Americans to retreat. Simultaneously, a battalion-sized guerrilla force led by Major John Vanderpool was dispatched to contain the Abe Provisional Battalion at Mabato Point, while elements of the 11th Airborne Division and the 1st Cavalry Division began clearing the routes to Fort McKinley. On February 15 and 16, the 129th conducted probing attacks on the New Police Station, the shoe factory, and Santa Teresita College, while tanks and artillery maintained consistent fire on all buildings still held by the Japanese. The 3rd Battalion of the 148th Regiment reached Manila Bay via Herran Street and then turned to assault the hospital from the south, while the 2nd Battalion made limited progress against the main hospital structures. The 12th Cavalry successfully entered La Salle University and the Japanese Club, and the 5th Cavalry pushed through Harrison Park, clearing Rizal Stadium, with the entire area being secured by February 18.

In the early hours of February 16, Yokoyama initiated his limited offensive, with the 31st Regiment advancing toward Novaliches while General Kobayashi’s three battalions attacked Marikina.The 112th Cavalry RCT, which had replaced the 12th Cavalry along the 1st Cavalry Division's line of communications, broke up the northern wing's counterattack between 15 and 18 February. In the Novaliches-Novaliches Dam area, and in a series of skirmishes further west and northwest, the 112th Cavalry RCT dispatched some 300 Japanese, losing only 2 men killed and 32 wounded. Un-co-ordinated from the start, the northern counterattack turned into a shambles, and the northern attack force withdrew in a disorganized manner before it accomplished anything. The Kobayashi Force's effort was turned back on the morning of the 16th, when American artillery caught this southern wing as it attempted to cross the Marikina River. During the next three days all Japanese attacks were piecemeal in nature and were thrown back with little difficulty by the 7th and 8th Cavalry Regiments, operating east and northeast of Manila. By 19 February, when the southern counterattack force also withdrew, the 2d Cavalry Brigade and support artillery had killed about 650 Japanese in the area west of the Marikina from Novaliches Dam south to the Pasig. The brigade lost about 15 men killed and 50 wounded.

Consequently, Yokoyama's only achievement was the escape of the remnants of the 3rd and 4th Naval Battalions from the Fort McKinley area, which was later occupied by American forces. Additionally, from February 15 to 20, the 511th Parachute Regiment thoroughly searched the Cavite Peninsula and the adjacent mainland but encountered only a few Japanese stragglers. Meanwhile, to secure the Bataan Peninsula, Hall divided his forces into two groups: East Force and South Force. The East Force, consisting of the recently arrived 1st Regiment and led by Brigadier-General William Spence, was tasked with advancing down the east coast to divert Japanese attention from the Mariveles landing, which was to be executed by Chase’s 151st Regiment. Accordingly, the 151st Regiment boarded Admiral Struble’s Task Group 78.3 vessels at Olongapo just as the 1st Regiment was passing through Orani and beginning its southward advance, reaching Pilar by the end of February 14. The following day, after conducting minesweeping and bombardment operations—during which the destroyers La Vallette and Radford were unfortunately disabled by mines—Struble successfully landed the 151st at Mariveles under machine-gun and rifle fire. The Americans found no Japanese forces before sunset, but during the night, they had to fend off a counterattack by approximately 100 enemy troops. During the night of 15-16 February an estimated 300 Japanese attacked the 1st Infantry's perimeter near Orion, but the U.S. regiment, losing 11 killed and 15 wounded, beat off the Japanese and killed 80 of them in a melee of confused, sometimes hand-to-hand fighting. The incident marked the end of organized Japanese resistance in southern Bataan.

The 151st spent the following days securing the Mariveles area while simultaneously sending patrols northward along both sides of the Bataan Peninsula. They connected with the 1st Regiment at Limay on February 18. By February 21, the Americans had advanced across Bataan to Bagac, encountering only abandoned defensive positions and a few Japanese stragglers. However, Nagayoshi’s remaining 1,000 troops managed to take refuge in the jungled slopes of Mount Natib, where elements of the 38th Division, the 6th Division, and Filipino guerrillas systematically hunted them down. While Bataan was being cleared, Generals MacArthur and Krueger were also planning the invasion of Corregidor Island. The assault plan involved Colonel George Jones’ 503rd Parachute Regiment airdropping onto the island, supported by a nearly simultaneous shore-to-shore operation conducted by the reinforced 3rd Battalion, 34th Regiment, from the recently secured Mariveles. 

The decision to employ paratroopers to make the principal assault against an objective of Corregidor's size and terrain merits attention. Shaped like a tadpole, with its bulbous head pointing west toward the South China Sea, Corregidor is but three and a half miles long and one and a half miles across at its point of greatest width. The prospective cost of amphibious assault was, indeed, one of the chief factors that led to a decision to use paratroopers. Planners saw the obvious risks in sending parachute troops against such a small and rough target, but in view of the GHQ SWPA estimate that the Japanese garrison numbered only 850 men, the cost of the airborne operation promised to be less than that involved in an amphibious attack. Krueger intended to land almost 3,000 troops on Corregidor on 16 February, over 2,000 of them by parachute. Another 1,000 men or more would come in by parachute or landing craft the next day. Planners hoped that such preponderant strength, combined with intensive air and naval bombardment, might render the seizure of the island nearly bloodless. An equally important (if not even more decisive) factor leading to the decision to employ paratroops was the desire to achieve surprise. GHQ SWPA and Sixth Army planners hoped that the Japanese on Corregidor would judge that no one in his right mind would even consider dropping a regiment of parachutists on such a target. The defenses, the planners thought, would probably be oriented entirely toward amphibious attack.

The attack was scheduled for February 16, with paratroopers set to land on a parade ground and a golf course at Topside. They would then immediately assault Malinta Hill before the Japanese garrison could recover from the shock of the preparatory air and naval bombardment and the surprise of the parachute drop, with the amphibious troops launching their attack two hours after the paratroopers began jumping. Although Corregidor had been under attack by Allied Air Forces since January 22, General Kenney’s forces intensified their assaults at the start of February. By February 16, the 5th and 13th Air Force planes had dropped approximately 3,125 tons of bombs on the island. Naval bombardment also commenced on February 13, in conjunction with the bombardment and minesweeping in preparation for the capture of Mariveles.

On the morning of February 16, air and surface forces conducted their final preliminary bombardment before the paradrop. Launching from Mindoro, the 317th Troop Carrier Group transported the first wave of the 503rd Parachute Regiment in two columns of C-47s, swiftly dropping them over Corregidor at 08:30. Encountering only sporadic Japanese rifle and machine-gun fire, the paratroopers successfully secured the Topside drop zones by 09:45. However, approximately 25% of the paratroopers were injured, and many others failed to land on Topside. One unexpected blessing resulted from the scattered drop of paratroopers in the 0830 lift. Captain Itagaki, having been informed that landing craft were assembling off Mariveles, had hurried with a small guard to an observation post near Breakwater Point, obviously more concerned with the imminent amphibious assault than with the possibility that paratroopers might drop out of the C-47's already in sight of Corregidor. Suddenly, his attention was rudely diverted as twenty-five to thirty paratroopers who had been blown over the cliffs near the point began pelting down around the observation post. Fired on by the Japanese, the small American group quickly assembled and attacked. In the ensuing skirmish eight Japanese, including Captain Itagaki, were killed. Effective control among the Japanese units, already rendered practically impossible by the destruction of the communications center during the preassault air and naval bombardment, now ceased altogether. Leaderless, the remaining Japanese were no longer capable of coordinated offensive or defensive efforts. Each group would fight on its own from isolated and widely separated strongpoints.

Meanwhile, the 3rd Battalion, 34th Regiment departed Mariveles Harbor on 25 LCMs and made their way to the western end of Corregidor, landing on the south beach at 10:28. Contrary to expectations, the first four waves faced no opposition as they came ashore. However, as the fifth wave arrived, Japanese machine-guns opened fire from Ramsay Ravine, Breakwater Point, and the cliffs at San Jose Point. Despite this, Companies K and L advanced quickly and established a strong position on top of Malinta Hill by 11:00. This ensured total surprise, as the paradrop effectively drew Japanese attention away from the amphibious craft approaching Corregidor. At 12:40, the second wave of the 503rd began to land successfully on the drop zones, facing only limited fire from Japanese automatic weapons. With these reinforcements, the paratroopers were positioned to secure the remainder of Topside by the end of the day. However, during the night, the infantrymen would need to fend off a series of small but determined Japanese counterattacks along the northern side of Malinta Hill.

For eight consecutive days leading up to February 23, the 3rd Battalion, 34th Regiment successfully defended against relentless banzai charges, mortar assaults, and a suicide squad of soldiers equipped with explosives, resulting in approximately 300 Japanese casualties. On the afternoon of 17 February the 1st Battalion, 503d Infantry, and other reinforcements reached Bottomside by landing craft. Japanese rifle and machine gun fire, most of which passed overhead, "expedited" the movement ashore, and the battalion soon joined the rest of the regiment on Topside. The troops already on Topside had spent the day expanding their hold, systematically reducing the first of the many Japanese bunkers, pillboxes, and underground defenses they were to encounter, and had developed a pattern for the destruction of the Japanese installations. First, aircraft or naval fire support ships--the air arm using napalm extensively--were called upon to strike positions accessible to these types of bombardment; then the infantry attacked almost as the last shell or bomb burst. When this method failed, the 503d's own 75-mm. pack howitzers and lesser weapons were brought forward for direct fire. Next, having stationed men with submachine guns and rifles at advantageous points to cover approaches to a Japanese position, infantry assault teams moved forward behind white phosphorus hand grenades and the extremely close support of flame thrower teams. To avoid backflash and assure the deepest possible penetration of cave defenses, flame thrower operators often projected their fuel unignited, and then used white phosphorus grenades to fire it. If the Japanese within the caves still could not be induced to give up the fight, engineer demolition experts blocked the cave entrances. One Japanese tactic was both advantageous and disadvantageous to the 503d Infantry. Each night small groups of Japanese would attempt to reoccupy positions cleared during the previous day. To the 503d, this often meant some dirty, repetitive work, and additional casualties. On the other hand, the Japanese sometimes reoccupied tactically indefensible positions that proved easy to take out. The 503d Infantry seems to have been happy to let the Japanese occasionally return to such positions, secure in the knowledge that the only result would be more Japanese killed at no cost to the attackers. The only way to keep the Japanese from reoccupying less vulnerable positions was to stop night infiltration, a process that in turn required the blocking of the underground passageways that abounded on Topside. By these methods Japanese casualties began to mount rapidly. On the 17th, for example, over 300 Japanese were killed; nearly 775 were killed the next day. In the same two days Rock Force's casualties were approximately 30 killed and 110 wounded.

The Japanese resistance at Topside finally crumbled two days later after the Americans effectively repelled a fierce counterattack. The last significant opposition, concentrated at Wheeler Point, concluded with a small-scale banzai charge on the morning of February 23. By the end of that day, the 503rd had largely cleared the western section of Corregidor. Following intense air and naval bombardments, the paratroopers launched a final assault on the eastern end of the island on February 24, systematically destroying several strongholds over the next two days. Shortly after 1100 on 26 February the Japanese on Corregidor executed their final, suicidal tour de force, blowing an underground arsenal at Monkey Point amid scenes of carnage on both sides. As the dust from terrific explosions settled, a hollow appeared where a small knoll had previously stood. Debris had flown as far as Topside where one man, almost a mile from the explosion, was injured by flying rock. Other debris hit a destroyer 2,000 yards offshore. A medium tank was hurled 50 yards through the air, most of its crew killed. Bits and pieces of American and Japanese troops splattered the ground; rock slides buried alive other men of both forces. Over 200 Japanese were killed outright, while Rock Force lost some 50 men killed and 150 wounded. This explosion signified the end of organized resistance on Corregidor, and by 16:00, elements of the 503rd Parachute Regiment had reached the island's eastern tip. Mopping-up operations continued until March 2, when Hall and Jones determined that the island was secure. Ultimately, by the conclusion of the battle, the Americans had suffered approximately 215 killed and 790 wounded, while the Japanese losses were estimated at 5,200 killed and 20 captured.

On February 17, in Manila, the 129th Regiment secured the damaged shoe factory and cleared several buildings along the south bank of the Pasig River before being relieved by the 145th Regiment. During 17 February, with the aid of support fires from the 1st Battalion, now on the south side of Herran Street, the 2d Battalion smashed its way into the two most easterly of the hospital's four wings and overran the last resistance in the Nurses' Dormitory and the Science Building. The advance might have gone faster had it not been necessary to evacuate patients and other Filipino civilians from the hospital. By dusk over 2,000 civilians had come out of the buildings; the 148th Infantry conducted 5,000 more to safety that night. At the end of the 17th the 148th had overcome almost all opposition except that at the Medical School and in a small group of buildings facing Padre Faura Street at the northwestern corner of the hospital grounds. The next day, the 145th cleared Santa Teresita College but could not establish a presence inside the New Police Station. Meanwhile, the 148th consolidated its gains before being relieved by the 5th Cavalry. The 11th Airborne Division began besieging the Abe Provisional Battalion at Mabato Point, ultimately destroying this unit by February 23.

On February 19, the 5th Cavalry launched an assault on and cleared the Medical School and Assumption College, while the 1st Squadron of the 12th Cavalry advanced north along the bay, facing strong opposition, and successfully reached Padre Faura Street. At the same time, the police station and San Pablo Church underwent intense artillery and tank bombardment, with the church eventually falling to the 145th by nightfall. After further artillery and tank fire nearly leveled the police station, American forces secured its ruins on February 20. The 145th also began attacking City Hall and the General Post Office, making minimal progress in the initial days. Supported by heavy bombardment, the 5th Cavalry managed to capture Rizal Hall and the Administration Building but was eventually forced to withdraw after the Japanese detonated significant explosives. The 12th Cavalry overcame the last resistance at the High Commissioner's residence and pressed onward to San Luis Street.

The next day, the 12th swiftly entered the Manila Hotel and successfully took control of the area after a fierce battle. Meanwhile, the 5th Cavalry captured the Administration Building with minimal resistance, but they did not secure Rizal Hall and University Hall until February 24. During this time, the 145th Regiment continued its assault on City Hall and the General Post Office, which ultimately fell by February 22. As a result, Griswold’s forces had effectively confined the remnants of Iwabuchi’s troops to Intramuros, the South Port Area, and the Philippine Commonwealth Government buildings at the southeastern edge of the Walled City, leaving behind a trail of destroyed and damaged public and private structures. The fall of Manila was imminent; however, we must now shift our focus away from the Philippines to cover the Burma offensives. As we last reported, by mid-February, General Messervy’s 4th Corps had successfully established a bridgehead over the Irrawaddy River at Nyaungu, while General Stopford’s 33rd Corps continued to advance towards Mandalay, with the 19th Indian Division moving toward Madaya by the end of the month. Concerned about the bridgehead established by the 20th Indian Division, General Kimura decided to withdraw the main force of the 18th Division, which was engaged with the 36th British Division at Myitson. Consequently, after leaving the 114th Regiment at Mongmit, General Naka began relocating the majority of his division to Hsumhsai and then to Mandalay. In addition to the 18th Division, Kimura assigned the Kanjo Force to the 15th Army, further instructing General Katamura to prepare a general offensive aimed at destroying Stopford’s bridgeheads while the reinforced 31st Division continued its counterattacks against the 20th Division.

As attention turned to Nyaungu, a flurry of activity ensued to transport supplies to the 255th Indian Tank Brigade and the 48th and 63rd Indian Motorized Brigades across the river using boats and barges. General Cowan devised a plan for these units to gather at Mahlaing, capture the Thabutkon airstrip, where the air-transportable 99th Indian Brigade would land, and ultimately encircle and take Meiktila. With all his units successfully across by February 21, Cowan launched his advance towards Meiktila, quickly taking Seywa and Ngathayauk with minimal resistance. The following day, British-Indian forces attacked Taungtha from two fronts, with the southern group facing some opposition at the village of Oyin. Despite the Japanese putting up fierce and determined resistance, they were ultimately overwhelmed by the superior firepower of the British tanks. Upon realizing this new threat to his rear, Kimura halted his previous offensive and swiftly redirected the 53rd Division to Taungtha to block the enemy's advance towards Meiktila. Meanwhile, to bolster Kimura’s focus on Mandalay, the 2nd British Division crossed the Irrawaddy near Ngazun on the night of February 24, encountering heavy opposition but managing to secure a bridgehead two days later. Nonetheless, by February 24, the 48th Brigade reached Taungtha ahead of Kimura’s reinforcements and captured the town with light resistance. In the afternoon, the 63rd Brigade and the tanks moved through and continued towards Mahlaing, arriving on February 25. The next day, the Mahlaing area was completely cleared, and the Thabutkon airstrip was successfully captured. Realizing the seriousness of the situation, Kimura quickly dispatched the 18th and 49th Divisions along with the remaining forces of the 53rd Division towards Meiktila,  but only the 1st Battalion, 168th Regiment under Colonel Yoshida would arrive in time.

At Meiktila, Major-General Kasuya Tomekichi, commander of No. 2 Field Transport, which had responsibility for all the transport units supporting the 15th and 33rd Armies, was put in charge of the defense of the town. Kasuya had approximately 2500 administrative and line of communications troops available, and another 2000 from various Japanese Army Air Force units, including the 52nd and 84th Airfield Battalions and the 36th Anti-Aircraft Battalion. The administrative and line of communications troops were hastily organized into three emergency infantry companies and a mobile reserve force. Any hospital patient who could walk or shoot was sent out to man a bunker. Kasuya set up a western and eastern sector for the defense of the town, with the dividing line being Meiktila's northern and southern artificial lakes. The troops in Meiktila hurriedly prepared bunkers throughout the town and laid mines and booby traps along the approaches. Kasuya opened up the ordnance depots around the town and ensured that all units were well supplied with medium and light machine-guns, and had plenty of ammunition.

Cowan quickly began airlifting troops from the 99th Brigade to Thabutkon on February 27, with the operation expected to conclude by March 2. During the airlift, armored car patrols advanced along the main road to Meiktila, where they encountered a formidable Japanese roadblock that the 63rd Brigade later destroyed. That evening, advance patrols observed fires in Meiktila as the Japanese started to destroy their supply depots. The Battle for Meiktila was imminent; however, while General Slim’s 14th Army continued its Extended Capital offensive, new developments were also occurring in northern and southern Burma. In the north, the 36th Division finally secured Myitson following the withdrawal of the 18th Division and began moving toward Mongmit. The 50th Chinese Division, bolstered by the 1st Chinese Separate Regiment, crossed the Myitnge River at Namtu but encountered fierce resistance, with the 113th Regiment launching nine separate counterattacks before relinquishing the bridgehead. Meanwhile, the 30th Chinese Division advanced toward Lashio, supported by Kachin guerrillas. However, General Wedemeyer and the Generalissimo decided to withdraw all Chinese-American troops back to China once Lashio was captured, allowing them to prepare for a potential offensive toward Canton and Hong Kong. In the south, the 82nd West African Division continued its push toward An, facing strong opposition from General Koba’s forces at the Dalet River, while the 63rd Indian Brigade readied for an amphibious assault on Ruywa. Additionally, with a robust garrison in the Tamandu sector, General Miyazaki planned to gather his remaining units at An and launch a counteroffensive to eliminate all enemy forces west of the pass.

Before he could proceed, the 53rd successfully landed at Ruywa on February 16 with minimal opposition. In the following days, British-Indian forces quickly secured the area. By February 22, the 2nd West African Brigade had also arrived at the beachhead and immediately began a swift advance eastward toward An, while the 74th Indian Brigade was being deployed. The 74th then launched an attack toward Tamandu and, on February 28, began assaulting the main defenses of the 111th Regiment. However, upon learning of the enemy's approach to Meiktila, General Sakurai ordered the 72nd Independent Mixed Brigade to attack the Nyaungu bridgehead after some earlier probing attacks had failed. He also instructed Miyazaki to send the Koba Detachment, primarily composed of the 154th Regiment, to reinforce Yenangyaung. Consequently, facing less resistance in the north, Dalet would ultimately fall to the West Africans by the end of the month.

In Manila, General Yokoyama planned a counterattack to isolate Allied forces, but chaos ensued as American troops advanced. Fierce street fighting within Manila led to significant casualties, marking a brutal struggle for control. Paratroopers launched a surprise assault on Corregidor, overwhelming Japanese defenses, but taking significant losses in the process. Despite injuries and challenges, they secured the island, leading to significant enemy casualties and the end of organized resistance.
