The Pacific War - week by week

- 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.

Last time we spoke about the return to Bataan. In late January, the 43rd Division secured the Rosario region, while the 25th and 6th Divisions eliminated enemy detachments and advanced towards Manila. General Krueger received reinforcements and planned a coordinated attack. On January 28, an assault began, with guerrillas aiding American forces in capturing strategic locations. A daring raid freed 522 POWs, while MacArthur planned further landings to cut off Japanese retreat. By January's end, American forces were poised for a final offensive, pushing closer to victory in Luzon. The ZigZag Pass became a fierce battleground, where Colonel Nagayoshi’s well-camouflaged defenses faced relentless assaults from American forces. Despite challenges, the 129th and 20th Regiments made strategic gains, while the 35th Regiment maneuvered through treacherous terrain. Meanwhile, paratroopers from the 511th struggled with scattered landings but secured key positions. As the fighting intensified, the Allies prepared for a decisive invasion of Iwo Jima, aiming to establish a stronghold for future operations against Japan.

As we last observed, by February 3, General Iwanaka’s 2nd Tank Division was fending off assaults from the 6th and 25th Divisions in the San Jose area but was on the verge of being encircled. Meanwhile, General Griswold’s 14th Corps had successfully taken control of Clark Field and was reorganizing for a final offensive against the Kembu Group. General Hall’s 11th Corps had landed on the Bataan Peninsula and was engaged in combat with the Nagayoshi Detachment at ZigZag Pass. Additionally, General Swing’s 11th Airborne Division had landed at Nasugbu and had successfully captured Tagaytay Ridge in preparation for an advance toward Manila from the south. The 37th and 1st Cavalry Divisions were advancing on Manila from the north, with the latter’s two Flying Columns reaching the outskirts of the Filipino capital. At this stage, the capital was defended by Admiral Iwabuchi’s Manila Naval Defense Force, which had consolidated its forces into three primary operational sectors: the Northern Force, led by Colonel Noguchi Katsuzo, responsible for Intramuros on the south bank and all areas of the city north of the Pasig; the Central Force, commanded by Iwabuchi himself, encompassing all of metropolitan Manila south of the Pasig River and extending inland to Guadalupe; and the Southern Force, under Captain Furuse Takesue, covering the Nichols Field and Fort McKinley sectors, as well as the Hagonoy Isthmus. Iwabuchi intended for the Noguchi Force to retreat to Intramuros after disabling the Pasig bridges, while other units carried out extensive demolitions of military infrastructure, including the port area, bridges, transportation systems, water supply, and electrical installations. However, since the Japanese did not anticipate the Americans' arrival for another two weeks, they were ill-prepared to execute these missions or launch any significant counterattacks.

Recognizing that the cavalry units were twelve hours ahead of the 148th Regiment, Griswold authorized General Mudge to enter the city. Consequently, late in the afternoon, the 8th Cavalry’s Flying Column encountered minimal resistance as it crossed the city limits and advanced towards the gates of Santo Tomas University, where nearly 4,000 American and Allied civilian internees were being held, facing severe shortages of food and medical supplies. Upon their arrival at Santo Tomas, the advance elements of the 8th Cavalry, a medium of the 44th Tank Battalion serving as a battering ram, broke through the gates of the campus wall. Inside, the Japanese Army guards--most of them Formosans--put up little fight and within a few minutes some 3500 internees were liberated amid scenes of pathos and joy none of the participating American troops will ever forget. But in another building away from the internees' main quarters some sixty Japanese under Lt. Col. Hayashi Toshio, the camp commander, held as hostages another 275 internees, mostly women and children. Hayashi demanded a guarantee for safe conduct from the ground for himself and his men before he would release the internees. General Chase, who had come into the university campus about an hour after the 8th Cavalry entered, had to accept the Japanese conditions. In the end, Hayashi obtained permission to lead his unit out with what arms they could carry in exchange for the release of the Allied internees held as hostages. They were then taken by the Americans to the outskirts of Manila early on February 5 and released. Meanwhile, Hayashi was subsequently killed in action.

While General Chase worked to secure the release of the internees, Troop G of the 8th Cavalry continued its march south towards the Pasig River but was ultimately compelled to retreat due to heavy fire from the Far Eastern University. Meanwhile, frustrated with the slow progress of General Jones’ 38th Division, Hall ordered the 34th Regiment to move past the 152nd and press the attack eastward. Unfortunately, Colonel William Jenna’s enveloping assault with the 1st Battalion also failed to penetrate Colonel Nagayoshi’s robust defenses. As a result, Jenna opted to deploy his entire regiment in a coordinated three-pronged attack, which commenced on February 4. Initially, the attack, supported by the 1st Battalion of the 152nd Regiment, showed promise; however, due to ongoing strong resistance, including intense mortar and artillery fire, the 34th Regiment had to relinquish much of the territory it had captured by dusk. To the north, the 149th Regiment resumed its advance along the bypass trail and successfully made contact with patrols from the 40th Division near Dinalupihan by the end of February 4, having already reached the town.

Looking northeast, with enemy armored units at Muñoz and Lupao effectively contained, the 161st Regiment successfully established roadblocks on Route 8 southeast of San Isidro. Most notably, the 1st Regiment entered San Jose in the morning with little resistance and quickly secured the area, thereby completely isolating the majority of the 2nd Tank Division before it could receive orders to withdraw. As a result, the 6th and 25th Divisions were able to methodically eliminate the enemy's isolated strongholds at their convenience. Further south, by the end of the day, the 8th Cavalry liberated 4,000 internees at Santo Tomas; Troop F also secured Malacañan Palace; the 2nd Squadron, 5th Cavalry advanced toward Quezon Bridge but faced strong resistance at Far Eastern University, where the enemy successfully destroyed the bridge before retreating; and the 148th Regiment entered Manila, moving south through the Tondo and Santa Cruz Districts to reach the northwest corner of Old Bilibid Prison, where they freed 800 prisoners of war and 530 civilian internees. Finally, to the south, the 2nd Battalion, 511th Parachute Regiment departed from Tagaytay Ridge along Route 17, swiftly passing through Imus and Zapote to secure the Las Piñas River bridge. The 1st Battalion followed in the late afternoon but was ultimately halted by mortar and artillery fire at Parañaque. On February 5, the paratroopers managed to cross the Parañaque and began advancing north along Route 1, engaging in house-to-house and pillbox-to-pillbox combat as they moved 2,000 yards north over the next two days.

Simultaneously, the majority of the 145th Regiment commenced operations in the densely populated Tondo District along the bay, while other units advanced into the San Nicolas and Binondo Districts to combat the fires ignited by Noguchi’s demolitions. Throughout February 5 the 37th Division's men had heard and observed Japanese demolitions in the area along and just north of the Pasig in the Binondo and San Nicolas Districts as well as in the North Port Area, on the 145th's right front. The Northern Force was firing and blowing up military stores and installations all through the area and, as these tasks were completed, was withdrawing south across the river. Insofar as 14th Corps observers could ascertain, there was no wanton destruction, and in all probability the fires resulting from the demolitions would have been confined to the North Port Area and the river banks had not an unseasonable change in the wind about 20:30 driven the flames north and west. The 37th Division, fearing that the flames would spread into residential districts, gathered all available demolitions and started destroying frame buildings in the path of the fire. The extent of these demolitions cannot be ascertained--although it is known that the work of destruction continued for nearly 24 hours--and is an academic point at best since the demolitions proved largely ineffectual in stopping the spread of the flames. The conflagration ran north from the river to Azcarraga Street and across that thoroughfare into the North Port Area and Tondo District. The flames were finally brought under control late on February 6 along the general line of Azcarraga Street, but only after the wind again changed direction.

The 148th Regiment fought its way to the Santa Cruz District but was unable to reach the bridges before they were destroyed. The 5th and 8th Cavalry Regiments cleared the eastern part of the city north of the Pasig with minimal resistance, and the 7th Cavalry secured the Novaliches Dam and the Balara Water Filters, which were found intact but rigged for demolition. To the northwest, the battle for ZigZag Pass continued. Dissatisfied with his progress, Hall had previously informed Jones that the exhibition of his division was the worst he had ever seen--a rather severe indictment of an entire division, as only the 152nd Regiment had yet seen any real action on Luzon. Furthermore, the 152nd was a green unit that had been in combat scarcely 48 hours by February 2. Nevertheless, as he believed that the 152nd had at most encountered only an outpost line of resistance, that the principal Japanese defenses lay a mile or so east of the horseshoe, and that the 152nd had found "nothing that an outfit ready to go forward could not overcome quickly", Hall assumed direct control over the 34th Regiment for the main assault and left only the 152nd under Jones’ command, which was to follow the 34th through the ZigZag to mop up bypassed pockets of Japanese resistance. Yet the fighting at the horseshoe on February 3 and 4 was equally disappointing, costing the 34th some 41 men killed, 131 wounded, and 6 missing while on the same days the 152nd lost 4 men killed, 48 wounded, and 1 missing. The 34th had extended the front a little to the north of the horseshoe and a bit east of the eastern leg, but neither the 34th nor the 152nd had made any substantial gains beyond the point the 152nd had reached on February 2. The Japanese still held strong positions north of the horseshoe and they still controlled the northeastern corner and about half the eastern leg. The 34th’s greatest contribution during the two days, perhaps, was to have helped convince Hall that the Japanese had strong defenses throughout the ZigZag area and that the regiment had indeed reached a Japanese main line of resistance. It had not been until evening on February 4 that Hall was convinced that the 34th and 152nd Regiments had encountered a well-defended Japanese line.

Hall instructed Jones to launch an eastward attack with all available forces. Although the initial phase of the attack was promising, the 2nd Battalion of the 34th Regiment became trapped and had to retreat. After sustaining significant casualties, Jenna ordered the 1st Battalion to fall back as well and halted the 3rd Battalion's advance. This left the 152nd Regiment, which achieved considerable progress and cleared much of the northern and central sections of the ridge; however, its 1st Battalion was ultimately ambushed at close range and forced to retreat in chaos during the night. The following day, due to heavy losses, the 34th Regiment was withdrawn from combat, and the reserve 151st Regiment was deployed to support the 152nd. The 2nd Battalion of the latter was also pulled back from the southeastern corner of the horseshoe as artillery focused on Nagayoshi’s defenses. Nevertheless, at noon, Hall called for another assault, prompting Jones to reluctantly advance the 152nd Regiment, with only its 3rd Battalion making significant headway against the northeast corner of the horseshoe.

Hall had already made his decision; he relieved Jones and appointed Brigadier-General Roy Easley to take temporary command, with General Chase scheduled to arrive on February 7 to lead the 38th Division. Looking westward, after a week of securing previously held areas, General Brush had positioned the 185th Regiment in the north and the 108th Regiment in the south, while the 160th Regiment maintained its positions at Storm King Mountain in preparation for a renewed assault on the Kembu Group. However, before the divisional attack could resume, the 160th Regiment became engaged in a fierce battle for McSevney Point, which was finally secured by dusk on February 8. After fending off several banzai-style counterattacks, the Americans learned on February 10 that the Takaya Detachment had retreated. Meanwhile, the 185th began its advance toward Snake Hill North on February 7, taking three days of intense fighting to capture half the ground leading to this objective. The 108th also moved westward on February 8, making slow progress as it cleared the paths to the Japanese hill strongholds. Further northwest, the 6th and 25th Divisions were conducting mop-up operations in the San Jose sector. By February 6, the 20th Regiment's pressure on Muñoz had resulted in the destruction of nearly 35 tanks, although another 20 remained operational. The next morning, Colonel Ida finally attempted to escape via Route 5; however, the entire Japanese column was successfully destroyed while the 20th Regiment secured Muñoz.

At Lupao, the 35th Regiment continued to push the Japanese garrison into an increasingly confined area. As a result, on the night of February 7, the defenders attempted to flee, with five tanks successfully breaking through the 35th’s perimeter. The dismounted Japanese forces in the town dispersed, and by noon on February 8, the 35th had taken control of Lupao with minimal resistance. Meanwhile, the Japanese garrison at San Isidro had retreated before the 161st Regiment could capture the town on February 6. The 63rd Regiment successfully took Rizal on February 7, while the 20th Regiment secured Bongabon and cleared the route to Cabanatuan on February 8. Strong patrols were then dispatched toward Dingalen and Baler Bays, which were found deserted by February 12. Back in Manila on February 7, the 37th Division assumed control of the eastern part of the city, while cavalry units advanced beyond the city limits to clear the suburbs east of the San Juan River, with the 8th Cavalry pushing toward San Juan del Monte despite heavy resistance. Most notably, under a strong artillery barrage, the 148th Regiment crossed the Pasig River in assault boats, facing intense machine-gun, mortar, and artillery fire. Despite this fierce opposition, two battalions managed to assemble in the Malacañan Gardens area by the end of the day. Further south, the 511th Parachute and the reinforced 188th Glider Regiment launched an unsuccessful coordinated attack on Nichols Field. Over the next two days, the 511th secured a narrow strip of land between the Parañaque River and the western runway of the airfield, overrunning some defenses at the northwest corner, while the 188th struggled to gain ground in the south and southeast.

On ZigZag, Chase managed to deploy three regiments for his initial assaults, with the 151st and 152nd Regiments attacking from the west, while the 149th Regiment advanced from the east. The 5th Air Force initiated an extensive bombing and strafing campaign against the pass, and corps and division artillery increased their support fire. Despite this, the Japanese stubbornly held their ground, and it wasn't until the evening of February 8 that the 151st and 152nd Regiments overcame the last significant defenses near the horseshoe area. On that day, the 7th Cavalry captured San Juan Reservoir, and the 8th Cavalry successfully attacked San Juan del Monte, completing the area’s reduction as the defenders retreated toward Montalban. The 145th Regiment launched a final assault on the Tondo District pocket, which would be completely eliminated the following day, while the 148th Regiment cleared the Pandacan District with minimal resistance. The 129th Regiment crossed the Pasig River in the afternoon and moved west toward Provisor Island but was halted by heavy fire at the Estero de Tonque.

On February 9, the 8th Cavalry secured El Deposito, an underground reservoir supplied by artesian wells, and advanced south to reach the north bank of the Pasig River. The 148th Regiment began clearing the Paco District but failed to eliminate a strongpoint at Paco Railroad Station and the nearby Concordia College and Paco School buildings. Meanwhile, Company G of the 129th Regiment managed to cross to Provisor and entered the boiler plant, only to be quickly repelled by a Japanese counterattack.

After an improvised evacuation overnight, tith close support--so close that the fifteen survivors had to keep prone--from the 2nd Battalion's mortars, Company G's isolated group hung on for the rest of the day while the battalion made plans to evacuate them so that artillery could again strike the island. After dark Company G's commander, Captain George West, swam across the Estero de Tonque dragging an engineer assault boat behind him. Although wounded, he shuttled his troops back to the east bank in the dim light of flames from burning buildings on and south of the island. When a count was taken about midnight, Company G totaled 17 casualties--6 men killed, 5 wounded, and 6 missing--among the 18 men, including Captain West, who had reached Provisor Island during the previous eighteen hours.

Despite facing strong resistance, Company E successfully crossed and captured the eastern half of the boiler plant. The Americans gradually cleared the remainder of the boiler house, but every attempt to venture outside drew fire from all available Japanese weapons in range of Provisor Island. At the same time, the 148th Regiment finally secured the Paco District after the enemy abandoned their stronghold during the night, allowing the Americans to gain control of the east bank of the Estero de Paco. The 1st Battalion of the 129th Regiment advanced to both this estero and the Estero de Tonque. The 8th Cavalry crossed the Pasig, establishing a bridgehead about 1,000 yards deep in the Philippine Racing Club area, while the 5th Cavalry moved south alongside the 8th, encountering only scattered resistance as they also crossed the Pasig at Makati. Swing’s forces consolidated their gains and established a solid line from the northwest corner to the southwest corner of Nichols Field, eliminating the last Japanese resistance on the western side, while elements of the 511th Parachute Regiment advanced along Route 1 nearly a mile beyond the field’s northwest corner. On this day, the 11th Airborne Division came under the control of the 14th Corps, with Griswold ordering Swing to maintain pressure on Nichols Field without launching a general assault toward Manila. Now, however, it was time to leave the Philippines and shift focus to Bougainville to cover the ongoing Australian offensive.

Following the capture of Pearl Ridge, Brigadier Stevenson’s 11th Brigade assumed control of the central and northern sectors, while General Bridgeford’s 3rd Division focused its efforts in the Jaba River region to prepare for an offensive southward. By the end of December, the 15th Battalion had landed in the Tavera River area, and the 47th Battalion launched an attack up the Jaba River to disrupt enemy forces. In the first week of January, Brigadier Monaghan redeployed his troops, with the 42nd Battalion and 2/8th Commando Squadron taking over from the 47th to enable its movement down the coast to support the 15th Battalion. As a result, the Australians swiftly occupied the mouth of the Adele River and secured the Tavera area. By January 12, the 47th Battalion had advanced to the mouth of the Hupai River; however, with the Japanese seemingly reinforcing the Kupon-Nigitan-Mendai area on the Australian flank, Monaghan decided to slow his advance while the 2/8th Commandos conducted reconnaissance toward the Pagana River. With no threats emerging, the 42nd Battalion relieved the 47th on January 17 and advanced unopposed to Mawaraka. In the subsequent days, a long-range patrol from the New Guinea Battalion landed by sea and moved forward to Motupena Point, where they caught a Japanese listening post by surprise. While Monaghan awaited relief from Brigadier Field’s 7th Brigade in late January, patrols ventured deep into the Sisiruai area and continued to scout beyond Mawaraka. Meanwhile, the 2/8th Commandos moved to Sovele Mission and patrolled the mountains toward Kieta, occasionally assisting the Kapikavi people in their guerrilla warfare against the Japanese.

While the 11th Brigade concentrated in its northern operations, patrols generally guided by native police were sent out for from 1 day to 6 days to probe forward through the bush. The 11th Battery relieved the 10th and it replaced its short 25-pounders with long 25-pounders, with their greater range, in order to support these deep patrols more effectively; from posts on Pearl Ridge and Keenan's Ridge observers directed the bombardment of the Japanese positions on the slopes beyond. The firing of the guns, far below at the foot of the Laruma escarpment, could not be heard at Pearl Ridge and the only warning that the Japanese had was the brief whistle of the approaching shells. Partly as a result of the skilful guidance of the native police the patrols killed many Japanese and suffered relatively small losses. The 26th Battalion, the first to do a tour of duty here, suffered its first death in action on January 7 when a patrol led by Lieutenant Davis met an enemy patrol. Private Smith died of wounds and three corporals were wounded as a result, so the hill where the clash occurred was then named Smith's Hill. As the 26th Battalion advanced toward Smith’s Hill, Stevenson had assembled Lieutenant-Colonel Joseph Kelly’s 31st/51st Battalion at Sipaai by January 7.

The strategy involved moving towards Soraken Harbour through extensive inland patrols designed to drive the enemy back to the coastal area, where they could be decisively defeated. Consequently, the main contingent of the 31st/51st began its advance along the coastal route, while a long-range patrol headed inland via Totokei towards Lalum. By January 16, the Australians reached Rakussia without any issues; however, in the following days, they would need to fight their way to Puto, as the flanking force was also advancing towards Kunamatoro. On January 21, the 31st/51st launched an assault on Tsimba Ridge, where the Japanese had set up their primary defensive positions. The determined defenders successfully repelled several attacks over the next few days, prompting the Australians to attempt an outflanking maneuver on January 25, with a company moving inland to cross the Genga River and attack Tsimba from the north. For the next six days, the Japanese launched strong counterattacks against this bridgehead but suffered significant losses. Ultimately, after a heavy artillery bombardment on February 6, the Australians were able to advance to the western end of the northern side of Tsimba, completely encircling the Japanese forces. The following day, the defenders counterattacked but were pushed back, yet they stubbornly held onto their remaining position at the western tip of the ridge. After an air and mortar assault, Tsimba was finally cleared on February 9, as the Japanese retreated towards the harbour during the night. In the subsequent two weeks, the Australians secured Lalum and the Gillman River, while another flanking force took control of Kunamatoro.

On February 22, the 31st/51st Battalion was relieved by the 26th Battalion. Subsequently, the 55th/53rd Battalion took over at Pearl Ridge, where it continued to advance along the Numa Numa trail to engage the majority of the 81st Regiment. The nature of the deep patrols may be illustrated by drawing on the report of the one which killed the largest number of Japanese (26 confirmed kills). Lieutenant Goodwin and 10 infantrymen of the 55th/53rd, with an artillery observer (Lieutenant Ford) and his team, a native police boy and 2 native scouts, set out on March 2 to gain topographical information and information about the enemy, and find suitable supply-dropping points. They were out for 5 days. On the first morning they saw signs of a Japanese patrol of 3 some 45 minutes ahead of them and traced their movements. The Australians moved 5400 yards that day. Next morning near the Numa Numa trail one of the natives reported that Japanese were nearby. Goodwin detailed 3 men to block the track and led 3 others in from the side to deal with the enemy. They crept stealthily forward and found 6 Japanese in a lean-to. Goodwin gave each man a target and all 6 of the enemy were killed. While Goodwin was examining the bodies there was a burst of fire from a ridge overlooking them. The Australians withdrew to dead ground, circled the enemy and marched on into his territory, the Japanese fire continuing for 15 minutes after they had gone. They travelled 7600 yards that day. The 4th was spent reconnoitring the area they had then reached. Next day they had moved some 5000 yards on the return journey when scouts reported Japanese round the junction of their native pad and a creek that lay ahead. Goodwin moved the patrol to a ridge overlooking the Japanese and sent 3 men to cover the track to the west. After killing 15 Japanese and throwing 15 grenades into the area, the patrol then moved 700 yards and bivouacked for the night. Next day—the 6th—6 hours of marching brought them back to their starting point. 

Meanwhile, in the south, Field initiated his own offensive by deploying the 61st Battalion to capture the Kupon-Nigitan-Mosina area, which was successfully taken by February 9. Concurrently, the 25th Battalion advanced along the Tavera despite facing strong resistance, eventually connecting with the 61st Battalion in the Mendai-Sisiruai area. The 9th Battalion also progressed along the Hupai, successfully occupying Makotowa by the end of January and then embarking on a challenging march toward Mosigetta, which was captured on February 16. The following day, a company from the 61st Battalion linked up with the 9th Battalion from the north. Additionally, after quickly securing the Sovele area, the 2/8th Commandos began reconnoitering the Sisiruai-Birosi area on February 2. By February 13, they had established a new base at Opai and discovered that the gardens north of the Puriata River were free of enemy forces. Furthermore, a detached company of the 25th Battalion traveled by barge from Motupena Point to Toko and began pushing inland toward Barara, with the remainder of the battalion expected to arrive shortly to support this advance. However, it is now time to shift focus from Bougainville to the ongoing Burma offensives.

Initially, in the north, General Matsuyama’s 56th Division began its retreat towards Hsenwi and Lashio, successfully breaching the roadblocks established by the 114th Regiment in late January. Meanwhile, the Mars Task Force struggled to dislodge the determined defenders at Namhpakka. Despite capturing Hpa-pen and executing a clever encirclement against Loikang in early February, they managed to take the ridge only after the Japanese had already completed their withdrawal to Hsenwi on February 4. The 56th Division then focused its efforts on the Lashio region, while the 4th, 55th, and 168th Regiments returned to their original divisions, with the 168th specifically tasked with defending Meiktila. On that same day, the first official convoy from the India-Burma Theater reached Kunming via the Ledo Road, which would later be renamed the Stilwell Road in honor of the individual who initiated this ambitious endeavor. Meanwhile, on February 1, General Festing’s 36th Division attempted to cross the Shweli River at Myitson but was met with heavy small arms fire from the Japanese. As a result, the British opted to mislead the enemy, stationing the 72nd Brigade, which included the 114th Regiment, on a small island while the 26th Brigade crossed downstream on February 8, successfully capturing Myitson two days later. In the following days, the 26th Brigade fortified its positions; however, General Naka decided to go on the offensive, deploying his 56th Regiment in increments as it advanced north from Mongmit. Consequently, the 114th and 56th Regiments launched a series of intense counterattacks against the 26th Brigade’s foothold, effectively containing the British-Indian forces, although they were unable to push them back across the river.

Simultaneously, the Chinese 1st Provisional Tank Group, leading the 30th Chinese Division southward, fought its way to Hsenwi on February 19. The 50th Chinese Division, which crossed the Shweli River without opposition, reached the significant nonferrous Bawdwin mines on February 20. Meanwhile, General Slim continued his Extended Capital offensive, with General Stopford’s 33rd Corps advancing towards Mandalay, while General Messervy’s 4th Corps quietly maneuvered through the Myittha valley toward the Irrawaddy River in the Chauk-Pakokku region. In early February, Stopford made persistent and determined attempts from the north to seize Mandalay, reinforcing the perception that this was Slim’s primary focus. By February 12, General Gracey’s 20th Indian Division had also arrived at Allagappa, where the 80th Brigade promptly began crossing the Irrawaddy. In the following days, the British-Indian forces would need to defend this bridgehead against fierce counterattacks from the 33rd Division. Additionally, negotiations began to persuade General Aung San’s Burma National Army to join the Allies. 

In Burma, one man above all others could see the writing on the wall for the Japanese. The Allies received news on January 1 that the Burmese military leader General Aung San and his Burma National Army (BNA) would be prepared to switch sides. An operation by Special Operations Executive (SOE) – codenamed Nation – was launched to liaise with the BNA and the leadership of another group, the Anti-Fascist Organization (AFO), and so facilitate this delicate transfer of loyalties. The first parachute drop of agents was to Toungoo on January 27 and comprised an all-Burma force. It reported that the BNA – or significant parts of it – was ready to turn, but that the AFO needed arming. A team parachuted into Burma on March 20 reported that action by the BNA would begin in a week. 

At the same time, General Evans’ 7th Indian Division was advancing toward the Irrawaddy, aiming to cross the river at Nyaungu. Comprehensive deception tactics, known as Operation Cloak, were implemented to disguise the Nyaungu crossings. The 28th East African Brigade feigned a southward movement to reclaim the Chauk and Yenangyaung oilfields, and dummy parachute drops were carried out east of Chauk to support this ruse. The 114th Indian Brigade also exerted significant pressure on Pakokku to create the impression that crossings were planned there as well. While the 33rd Indian Brigade stealthily approached Nyaungu via Kanhla, the 48th and 63rd Brigades of the 17th Indian Division, reorganized as motorized units, departed from Imphal and began their descent down the Myitha valley.

Worried about the enemy buildup near Nyaungu and Pakokkku, General Tanaka opted to send one battalion from the 215th Regiment to bolster defenses in Nyaungu and Pagan. From February 10 to 12, the 114th Brigade successfully captured Pakokku, while the 28th Brigade took control of Seikpyu. Although the 114th Brigade managed to fend off strong enemy counterattacks, elements of the 153rd Regiment recaptured Seikpyu after several days of intense fighting. On the morning of February 14, the 2nd Battalion of the South Lancashire Regiment crossed the Irrawaddy, landing on a beach a mile northeast of Nyaungu and quickly securing the high ground above, followed shortly by the rest of the 33rd Brigade. The next day, the 89th Indian Brigade began crossing the river, with Evans’ forces advancing outward and successfully clearing the Nyaungu area by the end of February 16. Meanwhile, to the south, General Christison’s 15th Corps continued its offensive in Arakan in early February. General Wood’s 25th Indian Division repelled fierce counterattacks from the 154th Regiment, while General Stockwell’s 82nd West African Division pursued the retreating Japanese forces. General Lomax’s 26th Indian Division chose to bypass the enemy stronghold at Yanbauk Chaung to the northeast, moving swiftly through Sane and engaging some delaying forces at Namudwe. Additionally, due to the perceived weakness in the boundary between the 28th and 15th Armies, General Sakurai had to send the Kanjo Force, centered around the 112th Regiment, to reinforce Yenangyaung. At this point, most of the 2nd Division had also been dispatched to Saigon to stage a coup against the French government in Indochina, leaving Sakurai with only the depleted 49th Division and 16th Regiment in reserve.

By 1944, with the war going against the Japanese after defeats in Burma and the Philippines, they then feared an Allied offensive in French Indochina. The Japanese were already suspicious of the French; the liberation of Paris in August 1944 raised further doubts as to where the loyalties of the colonial administration lay. The Vichy regime by this time had ceased to exist, but its colonial administration was still in place in Indochina, though Admiral Jean Decoux had recognized and contacted the Provisional Government of the French Republic led by Charles de Gaulle. Decoux got a cold response from de Gaulle and was stripped of his powers as governor general but was ordered to maintain his post with orders to deceive the Japanese. Instead Decoux's army commander General Eugène Mordant secretly became the Provisional Government's delegate and the head of all resistance and underground activities in Indochina. Following the South China Sea Raid in January 1945, six US navy pilots were shot down but were picked up by French military authorities and housed in the central prison of Saigon for safe keeping. The French refused to give the Americans up and when the Japanese prepared to storm the prison the men were smuggled out. The Japanese then demanded their surrender but Decoux refused, so Lieutenant-General Tsuchihashi Yuitsu, the Japanese commander of the 38th Army, decided to begin preparations for a coup against the French colonial administration in Indochina.

As a result, he chose to send the Kamui Detachment, centered around the 55th Cavalry Regiment, to Letpadan to bolster his reserve forces, which also welcomed the arrival of the Sakura Detachment in Prome. Meanwhile, Lomax’s troops successfully captured Ramree village on February 8, forcing the Japanese defenders to retreat chaotically to the mainland. The remainder of the month was spent clearing the rest of the island. Consequently, Stockwell was instructed to bypass Kangaw and initiate an advance toward An. However, by February 15, the 154th Regiment had started to withdraw to positions west and north of the Dalet River, while the Matsu Detachment hurried toward Tamandu, the next target for an amphibious assault.

The battle for Manila was just kicking up. Over 4000 internees at Santo Tomas had been rescued and hard earned victories were being won over the formidable ZigZag Pass. Meanwhile the efforts on Bougainville continued against fierce and stubborn Japanese resistance.

- 167 - Pacific War Podcast - the Return to Bataan - January 28 - February 4 - , 1945

Last time we spoke about the Mandalay Offensive. In the midst of intense warfare, General Krueger positioned his troops strategically to bolster the assault at Rosario. As the American forces repelled counterattacks and advanced, they faced fierce Japanese resistance, particularly at Binalonan and Hill 600. Despite heavy casualties, the Americans gradually gained ground, clearing key areas and preparing for further offensives. Meanwhile, Japanese defenses were fortified but weakened by shortages. As battles raged, both sides braced for decisive confrontations in the ongoing struggle for control of Luzon. In a fierce battle across the hills of Luzon, the 103rd Regiment aimed to secure key positions but faced heavy resistance, capturing Hill 800 by nightfall. The 172nd Regiment achieved surprise at Hill 900, while other regiments advanced under relentless fire. Meanwhile, in Burma, the British-Indian forces captured Shwebo, pushing deeper against Japanese defenses. The Mars Task Force disrupted supply lines, leading to a Japanese retreat. Amidst the chaos, both sides suffered heavy losses, marking a pivotal moment in the campaign.

By the end of January, as previously noted on Luzon, the 43rd Division had secured most of the Rosario region and Route 3 from Pozorrubio to the crucial junction with Route 11. The 25th Division had successfully eliminated the Shigemi Detachment at San Manuel, while the 6th Division had cleared the Cabaruan Hills and established outposts between Balungao and Guimba. Meanwhile, the 14th Corps had advanced to Clark Field, where it was engaged in a fierce battle with the Kembu Group. By January 27, the 40th Division had breached General Tsukada’s northern defensive line, and the 37th Division had fortified Mabalacat, Angeles, and Runway No. 1 in preparation for the final push toward Manila. On that same day, General Krueger received significant reinforcements, with the arrival of the 1st Cavalry Division, the 32nd Division, and the 112th Cavalry Regiment at Lingayen Gulf. He planned to gather the cavalry division at Guimba to launch a coordinated advance toward the capital along the eastern side of the Central Plains via Route 5. After returning the reserve 35th Regiment to General Mullins, Krueger intended to deploy the 32nd Division, minus the 126th Regiment in Army Reserve, to the San Manuel-Asingan area. This would allow the 25th and 6th Divisions to narrow their fronts and continue south and southeast toward the Licab-Lupao line with reduced risk of exposing the 1st Corps’ flank. Additionally, this strategy would enable the 37th Division to resume its advance toward Manila. However, General Griswold wanted to push Tsukada’s forces further into the Zambales Mountains first, directing General Beightler to assault the enemy’s southern defensive line centered around Fort Stotsenburg, while only the 148th Regiment and the 37th Reconnaissance Troop moved south along Route 3 to San Fernando.

On January 28, the attack commenced as planned, with the 129th Regiment advancing westward through Runway No. 2, but it was quickly halted by the formidable forward defenses of the Eguchi Detachment. Meanwhile, with the assistance of Filipino guerrillas, reconnaissance units from the 37th Division successfully secured the San Fernando bridges intact. To the north of the Bamban River, the 160th Regiment faced unexpectedly light resistance as it moved along its ridge line to capture open-crested Hill 620, although it would later encounter stronger opposition when it reached the main defenses of the Takaya Detachment. At the same time, General Patrick began gathering the 1st and 20th Regiments at Guimba and Victoria, while the 6th Reconnaissance Troop advanced toward Cabanatuan, where they identified a significant Japanese concentration. Further north, the 35th Regiment advanced unopposed to barrio Gonzales, while the 27th Regiment moved overland and successfully dislodged a Japanese outpost from barrio Pemienta.

Meanwhile, MacArthur was planning a secondary landing on the Zambales coast of Luzon, assigning Major-General Charles Hall’s 11th Corps, which included the 38th Division and the 34th Regiment, to land at San Antonio and quickly advance across the base of Bataan to prevent any significant Japanese retreat into the peninsula. He also aimed to divert the Kembu Group’s attention to relieve some pressure on the 14th Corps. However, General Yamashita had no intention of retreating to Bataan and had only dispatched Colonel Nagayoshi Sanenobu’s 39th Regiment to defend the peninsula and the Kembu Group’s right flank. On January 26, Hall’s 11th Corps had departed Leyte Island aboard vessels from Admiral Struble’s Task Group 78.3, heading directly to Luzon for the San Antonio landing, codenamed Operation Mike 7.

The convoy reached its destination on the morning of January 29. After receiving reports from Filipino guerrillas indicating that there were no Japanese forces in the landing area, Struble decided to cancel the planned pre-assault bombardment. Instead, he ordered Hall’s four regiments to land simultaneously across a nearly six-mile stretch of coastline from San Antonio. Upon landing, the 151st Regiment secured San Felipe and San Antonio, while the 149th Regiment quickly moved inland to capture the San Marcelino Airstrip. However, they discovered that guerrillas led by Captain Ramon Magsaysay had already taken control of the airstrip three days prior. Before nightfall, the 34th Regiment and the 24th Reconnaissance Troop advanced south along Route 7 to the northern shore of Subic Bay. To the east, the 160th Regiment made significant progress, advancing nearly two miles southwest and breaching a stronghold at the center of the Takaya Detachment. The 129th Regiment also managed to penetrate enemy defenses into Fort Stotsenburg but was halted at barrio Tacondo by six tanks from the Yanagimoto Detachment. Despite this setback, the inability of the Japanese counterattacks to reclaim lost territory compelled Tsukada to order the Eguchi and Yanagimoto Detachments to retreat to their main line of resistance. Meanwhile, further north, units from the 1st and 20th Regiments successfully captured Licab and Talavera, cutting off the road between Cabanatuan and Muñoz. The 27th Regiment engaged a small tank-artillery force from the 2nd Tank Division that had become trapped along the highway between Gonzales and Pemienta. 

With the rapid advances of the 6th and 25th Divisions, the 2nd Tank Division main strength in the Tayug-Triangle Hill area was in danger of being cut off from its sole remaining escape route into the northern bastion via San Jose and Highway 5. To meet the new situation, General Iwanaka was directed to pull back all remaining division strength from the Tayug-Umingan and Triangle Hill sectors with the exception of small outpost forces to be left at Gonzales and Umingan to delay an enemy advance from the northwest. The division was instead to concentrate the bulk of its forces in a triangular-shaped area bounded by Lupao, Muñoz and Rizal. These new dispositions had barely been effected when enemy elements swept around the outpost force at Gonzales and cut its withdrawal route to Umingan, forcing the detachment to withdraw through the hills after destroying most of its tanks and all of its mechanized artillery. From 20:00 on the 29th until 04:30 the next morning the force tried unsuccessfully to break through the Pemienta perimeter, against a sharp enemy. By the time the action had ended the 27th Regiment had killed 125 Japanese and had destroyed 8 tanks, 8 artillery prime movers, 4 tractors, 8 105-mm howitzers and 5 trucks, while only losing about 15 men killed and 45 wounded. Only four tanks succeeded in breaking through the enemy encirclement and escaped along the highway to Umingan. The next day, the 27th Regiment began positioning itself to attack Umingan from the north and northwest, while the 35th Regiment started preparations for a holding attack from the west and southwest.

In an effort to avert the mass execution of prisoners of war at Cabanatuan, Lieutenant-Colonel Henry Mucci led a contingent of approximately 233 men, composed of Filipino guerrillas, soldiers from the Alamo Scouts, and Mucci’s 6th Ranger Battalion. They traversed 30 miles cross-country between January 28 and 30 to liberate 522 weakened prisoners during the night. Most of the prisoners had vacated the camp by 2010 hours. Rangers and guerrillas had to carry most, piggy-backing them or making hasty litters from rifles and shirts. It was 2 miles to the Pampanga River, where carts waited to take them to Platero to be treated, fed, and organized. Many were still in shock and had not yet fully understood that they were free. At 2040 hours, Capt Prince was at the Pampanga River supervising the loading of stumbling prisoners into 25 carts as Rangers and prisoners trickled in. The rest of the Scouts established an ambush at the crossing site. At 2045 hours, one hour after the raid was launched, Prince fired the third red flare and departed for Balangkare. The loaded carabao carts were ordered on their way to Balangkare at 2145 hours. 

Meanwhile Major Robert Lapham’s guerrilla forces provided cover for their escape, successfully returning them to Allied lines on January 31. During this operation, around 270 Japanese soldiers were killed at the camp, with an additional 900 casualties along the Cabu River. Over 270 Japanese lay dead or dying in the smoldering camp; most of the wounded dying by dawn as no aid was forthcoming. Japanese bodies were literally stacked at the Cabu bridge and scores more littered the riverside woods. The 359th Battalion had ceased to exist. In the morning, battalion commander Capt Oyanu was still alive, but most of his officers were dead. Only 255 men of 1,200 survived and most were wounded.

 

In contrast, the Americans suffered only 2 fatalities and 7 wounded, along with 12 wounded Filipinos and 2 dead prisoners. Fortunately, the anticipated retaliation against the Filipino population did not occur, as the Japanese retreated from the area within a day of the raid, while the 20th Regiment secured the road junction barrio of Baloc and began advancing toward Muñoz. On January 30, Griswold continued his vigorous offensive against Clark Field; the 129th Regiment cleared the hills near Dolores and took control of the abandoned Fort Stotsenburg area, while the 160th Regiment made only 500 yards of progress against the determined Takaya Detachment. The 108th Regiment finally captured Hill 5 and Thrall Hill. Further south, patrols from the 37th Division reached within a mile of Calumpit and the Pampanga River, and on Bataan, the 34th Regiment took Olongapo after a fierce skirmish, while the 2nd Battalion of the 151st Regiment captured Grande Island at the entrance to Subic Bay.

At the same time, MacArthur was strategizing another secondary landing on Luzon, this time utilizing General Swing’s 11th Airborne Division to assault Nasugbu, located 45 miles southwest of Manila. With this operation, MacArthur aimed to initiate a southern advance toward Manila while simultaneously hindering Japanese forces in southern Luzon from moving north to challenge Krueger’s main offensive. General Eichelberger intended to deploy the 187th and 188th Glider Regiments and advance them approximately twenty miles along Route 17 to Tagaytay Ridge. There, the 511th Parachute Regiment would conduct an airdrop to secure the ridge for the ground troops and capture adjacent sections of Route 17 before the Japanese could regroup to defend the highway. In opposition, General Yokoyama had assigned only the Fuji Force to defend the area south of Manila. This force, centered around Colonel Fujishige Masatoshi’s reinforced 17th Regiment, had only deployed the 3rd Battalion of the 31st Regiment in the Tagaytay Ridge region, with a small outpost at Nasugbu and its main defenses positioned on Mounts Cariliao and Batulao. At this stage, Yokoyama was nearing completion of the organization of the diverse Shimbu Group forces east of Manila into a cohesive combat task force. To the north, near Ipo, he had stationed the Kawashima Force, which was composed of the 82nd Brigade and the 31st Regiment. To the south, the main contingent of the former Manila Defense Force had been relocated from the Philippine capital and renamed the Kobayashi Force, guarding the Wawa-Montalban area. However, the departure of General Tsuda’s 105th Division to the northern stronghold had created a significant gap in the Shimbu Group’s defenses. Although Yokoyama intended to address this vulnerability with the Noguchi Detachment, Major-General Noguchi Susumu's troops were still in the midst of a lengthy march from the Bicol Peninsula by the end of January.

As a temporary solution, the Okita Detachment, a composite force consisting of five battalions centered around the 186th Independent Battalion, and the Kuromiya Detachment, a three-battalion unit based on the 181st Independent Battalion, were deployed in the Bosoboso-Antipolo region. Meanwhile, the Kogure Detachment, organized around the 1st Surface Raiding Base Force, was stationed at Lamon Bay. Manila was entrusted to Rear-Admiral Iwabuchi Sanji’s Manila Naval Defense Force, which included approximately 13,700 naval personnel from the 31st Special Base Force responsible for defending the islands of Manila Bay and the capital, along with some Army reinforcements.

On January 27, Swing’s 11th Airborne Division departed from Leyte Island aboard ships from Admiral Fechteler’s Task Group 78.2, heading directly to Nasugbu Bay to carry out Operation Mike 6. Following an uneventful journey and a brief preliminary bombardment on January 31, the 188th Glider Regiment successfully landed with minimal resistance and quickly advanced inland toward the Palico River, aiming for the section of Route 17 that leads to Tagaytay Ridge. Pleased with the initial landing, Swing subsequently deployed the 187th Glider Regiment and the division artillery, which began to relieve the rear elements of the 188th by midday. At the same time, the majority of the 188th secured the Palico bridge and crossed the river to reach Route 17.

Further north, under pressure from MacArthur and Krueger, the 148th Regiment successfully crossed the Pampanga River and captured Calumpit, just as Beightler was dispatching the 145th Regiment along Route 3 to assist in the advance toward Manila. At Clark Field, the 108th Regiment was patrolling forward, while the 160th Regiment faced challenges in breaking through enemy defenses. Meanwhile, the 129th Regiment launched an attack on the main positions of the Eguchi Detachment at Top of the World hill, successfully securing its steep, grassy southern and southeastern slopes.

On Bataan, General Jones sent the 152nd Regiment to travel through Olongapo and advance east along Route 7, while the 149th Regiment moved east toward Dinalupihan via a challenging trail located about 1,200 yards north of the highway. By the end of January, the 32nd Division had successfully taken control of the recently vacated Tayug area. The 6th and 25th Divisions reorganized in preparation for their final push towards San Jose, and the 1st Cavalry Division gathered at Guimba. The World War II brigade structure of Maj. Gen. Verne D. Mudge's dismounted 1st Cavalry Division differed greatly from that of the triangular infantry division of the period. Instead of three infantry regiments the 1st Cavalry Division had four cavalry regiments--the 5th and 12th in the 1st Cavalry Brigade, the 7th and 8th in the 2d Cavalry Brigade. Each regiment had two cavalry squadrons, each smaller than an infantry battalion, as opposed to the three battalions of an infantry regiment. Each cavalry regiment contained a weapons troop armed with 81-mm. mortars, .30-caliber and .50-caliber machine guns, and bazookas, but there was no heavy weapons troop within each squadron. The cavalry regiments lacked the antitank and cannon companies of an infantry regiment. 1st Cavalry Division Artillery was composed of one 75-mm. howitzer battalion, three 105-mm. howitzer battalions, and, for obvious reasons, an attached 155-mm. howitzer battalion. Reinforcing combat and service attachments brought the division's strength up to nearly 15,000 men, somewhat less than the strength of the reinforced 37th Division at the same time. On paper, each of the four cavalry regiments numbered 1,750 men--in contrast to the 3,000-odd of an infantry regiment--but none of the 1st Cavalry Division's regiments was up to strength. The division had received few replacements since entering combat on Leyte in October, and it had come to Luzon after very little rest from its arduous campaign through Leyte's mountains.

The 1st Cavalry division was ready to advance towards Cabanatuan as General Mudge dispatched two reinforced motorized squadrons. On February 1, the Flying Columns, led by General Chase, crossed the Pampanga River and began their southern march with minimal resistance. As a result, Cabanatuan and Gapan were quickly captured, although some opposition was encountered south of the Peñaranda River. Meanwhile, the 188th Glider Regiment continued its advance towards Tagaytay Ridge, facing heavy enemy fire from Mount Cariliao but still managing to secure the important Mount Aiming. The 148th Regiment swiftly moved down Route 3 and captured Malolos with little resistance. However, the 152nd Regiment faced increasingly strong resistance at ZigZag Pass.

While more rugged terrain than the ZigZag Pass area is to be found on Luzon, few pieces of ground combine to the same degree both roughness and dense jungle. Route 7 twists violently through the pass, following a line of least terrain resistance that wild pigs must originally have established. The jungle flora in the region is so thick that one can step 5 yards off the highway and not be able to see the road. The Japanese had honeycombed every hill and knoll at the ZigZag with foxholes linked by tunnels or trenches; at particularly advantageous points they had constructed strongpoints centered on log and dirt pillboxes. All the defenses were well camouflaged, for rich jungle foliage covered most positions, indicating that many had been prepared with great care and had been constructed well before Colonel Nagayoshi's 39th Regiment had reached the area in December. Colonel Nagayoshi had plenty of food and ammunition for a prolonged stand, and he also possessed numerous mortars and machine-guns. His artillery, however, was inadequate for the task at hand and he lacked certain types of medical supplies, especially malaria preventatives and cures. He had so scattered his mortars and artillery in order to protect them against American artillery and air strikes that his troops would often have difficulty massing their fires. Finally, his defensive line was scarcely 2000 yards wide northwest to southeast, thus rendering his whole position susceptible to vigorous outflanking maneuvers. On the other hand, he had good troops, well-prepared positions, and excellent defensive terrain.

The 129th Regiment secured the summit of Top of the World hill, effectively ensuring Clark Field's protection from all but long-range artillery fire. The 20th Regiment launched its initial attack on Muñoz, which was thwarted by Colonel Ida Kumpei’s tanks fortified as pillboxes. Additionally, the 27th Regiment attempted to advance towards Umingan but was unable to break through, while elements of the 35th Regiment bypassed this area and occupied barrio San Roque.

February 2 mirrored the previous day in the San Jose sector, as the 20th and 27th Regiments continued their battle against the determined Japanese defenders. Meanwhile, Mullins dispatched the 35th Regiment in a two-pronged maneuver towards Umingan, successfully clearing most of the town by noon. In an effort to recover lost time, Mullins then directed the 35th toward Lupao in the afternoon, but its leading battalion was ultimately halted by intense Japanese artillery, mortar, and machine-gun fire. With their forward units stalled at Muñoz and Lupao, Patrick and Mullins resorted to flanking tactics. Accordingly, Patrick sent the 1st Regiment along the Talavera River to attack San Jose from the southeast, while the 63rd Regiment attempted to bypass Muñoz to the east and rejoin Route 5 north of the town. In turn, Mullins ordered the 161st Regiment to move cross-country to positions on Route 99 south of Lupao, then advance to Route 8 between San Isidro and San Jose while the 35th surrounded and cleared Lupao. However, on this day, the 105th Division successfully evacuated San Jose along with its stockpiled ammunition, regrouping north at Puncan and rendering the entire San Jose offensive ineffective. Simultaneously, Chase’s Flying Columns passed through Gapan and entered Sabang, fording the Angat River to launch two simultaneous advances to the south and east. The 148th Regiment secured Plaridel after a brief but fierce skirmish, while the 152nd Regiment faced setbacks in the ZigZag Pass due to nighttime Japanese counterattacks and artillery fire. The 149th Regiment became disoriented and had to return to Olongapo, and the 188th Glider Regiment managed to break through to barrio Aga amidst heavy resistance, while the 1st Battalion of the 187th Glider Regiment moved forward to begin the assault toward Tagaytay.

On February 3, Swing’s glider infantry launched an assault on the western end of Tagaytay, while paratroopers from the 511th Parachute Regiment began to drop along the ridge in a rather scattered manner. The first echelon of the 511th, about 915 in all, had come to Tagaytay Ridge aboard 48 C-47 aircraft of the 317th Troop Carrier Group. The planes had flown north from Mindoro to approach Tagaytay Ridge from the northeast in order to avoid fire from Japanese anti-aircraft weapons west of the drop zone. The first 18 planes, carrying about 345 troops, dropped over the assigned area. At this juncture, planes from succeeding flights were nearly 6 miles and 3 minutes behind the lead aircraft. About 08:20 one of these later planes dumped out a couple of bundles of supplies. Taking this as a signal that they were over the proper drop zone, 'troopers of the succeeding 30 planes began jumping. Aircraft pilots, realizing they had not yet reached the proper point, attempted to halt the jumping, but the 511th's jump-masters continued sending the paratroopers out. Most of them landed almost 5 miles east-northeast of the assigned drop zone. A second group of 51 C-47s began approaching the drop area about 12:10. Some 80 men from the first 5 aircraft of this group landed in the proper place. The rest started out of their planes when they saw on the ground the collapsed chutes of the first misplaced jump. In the end, only 425 men landed on the assigned drop zone; the others, about 1325 in all, made scattered landings 4.5 to 6 miles to the east and northeast. The 11th Airborne Division, blaming the 317th Troop Carrier Group for the premature dropping, reported that the "true reason was the refusal of the Air Force to cooperate in a combined training program for Airborne and Air Force troops." In any event, it appears that some lack of jump discipline within the 511th contributed to the scattered, premature jumping.

Fortunately for them, they encountered minimal resistance as they secured the unoccupied ridge. To the north, the 148th Regiment continued its advance southward, facing delays at several tidal streams that were unbridged and unfordable, but managed to reach a point two miles south of Marilao by day’s end. At the same time, the 5th Cavalry’s Flying Column destroyed a Japanese outpost at Angat and moved through the guerrilla-held Norzagaray before crossing the Santa Maria River to join the 8th Cavalry’s Flying Column, which had already progressed to Talipapa and was nearing the outskirts of Manila. Meanwhile, the 27th Regiment successfully eliminated the remaining enemy pockets at Umingan; the 3rd Battalion of the 35th Regiment, advancing over elevated terrain northeast of Lupao, established a position on Route 8 approximately 1500 yards southeast of Lupao, while the rest of the regiment continued to launch unsuccessful frontal assaults on the town. The 20th Regiment managed to overrun a few Japanese strongholds at Muñoz but was unable to break through.

On 3 February the 2d Battalion, 20th Infantry, moved in on the northwest, but could not reach Route 99 in its sector. The 3d Battalion pushed across that road at the southwest corner of Muñoz, but gained only half a block into the main section of the town. The 1st Battalion, on the south side of Muñoz, made negligible progress. By dusk, the 20th Infantry had overrun a few Japanese strongpoints, but in order to hold its gains had had to destroy completely and physically occupy every position it had reached so far. Muñoz, General Patrick had begun to realize, was going to be a costly, hard, and time-consuming nut to crack. The 20th Infantry had not yet closed with the main Japanese defenses, but had spent most of the last three days pinned down by Japanese artillery, tank, and machine gun fire. Only by hugging the ground and taking advantage of the little cover even shattered tree stumps afforded had the regiment kept its casualties down to 15 men killed and 90 wounded. Meanwhile the 63rd Regiment successfully bypassed Muñoz and advanced up Route 5 toward Caanawan; and the 1st Regiment similarly advanced along the San Jose-Rizal road, assembling at two points 1000 yards south and 1500 yards east of San Jose. Now, however, it is time to leave Luzon and head toward the Central Pacific.

Following the successful capture of the Marianas and the establishment of B-29 Superfortress air bases on these islands, the Allies were finally able to conclude Operation Matterhorn and cease using bases in China and India for conducting raids on the Japanese mainland and other targets in East Asia. Between June 5, 1944, and January 17, 1945, General LeMay’s 20th Bomber Command executed a total of 29 combat missions, inflicting significant damage on key military installations in southern Japan, Manchuria, Formosa, and Indochina, with a total loss of 73 B-29s. Meanwhile, General Hansell’s 21st Bomber Command, reinforced by the 313th Bombardment Wing, struggled to achieve similar outcomes in both daylight precision bombing and area incendiary bombing, with the first three missions of January yielding the same disappointing results as those in December and November. 

On January 3rd, Norstad's incendiary test mission was run on 3 January, when ninety-seven B-29's got off for Nagoya. Each plane carried a mixed load of bombs -14 x 350-pound M18 IB clusters fuzed to open at 8,000 feet and one 420-pound fragmentation cluster fuzed to open 1,000 feet below releasing altitude. What with aborts and planes straying from course, only fifty-seven bombed the urban area designated as primary target, most of them releasing visually though cloud cover was rated as 6/10. Some fires were started but there was no holocaust. Smoke rising to 20,000 feet combined with cloud to make observation of results impossible for the attackers. As a test, then, the mission was inconclusive. To the citizens of Nagoya, who were better informed than intelligence officers of 21st Bomber Command, the damage seemed slight. On January 9th, having satisfied Norstad's requirement, the command returned to its program of precision bombing against aircraft factories. Performance for the most part was of a piece with what had gone before. On 9 January 1945 seventy-two B-29's were sent against Musashino near Tokyo. High winds broke up the formations so that only eighteen planes were able to bomb the target; twenty-four bombs, widely scattered in the plant area, destroyed one warehouse and damaged two others-a slight return for the effort expended and the six B-29's lost. On January 14th, at the Mitsubishi Aircraft Works at Nagoya on the 14th, precision bombing was again less than precise. Seventy-three B-29's were airborne and forty bombed, getting four GP's-one ton-into the No. 5 Works area and damaging three buildings.

Frustrated by this, Hansell increasingly blamed his crews for the unsatisfactory outcomes. Remarkably, he would only achieve his first fully successful B-29 attack on his final mission of the war. The target for the January 19 strike was virgin, a plant of the Kawasaki Aircraft Industries Company located 2 miles northwest of Akashi, a village on the Inland Sea some 12 miles west of Kobe. The Akashi works housed Kawasaki's general headquarters and one of the company's two large production units, which built the twin-engine fighters Nick and Randy and engines for Tony, Oscar and Frank fighters. Smaller than Nakajima and Mitsubishi, Kawasaki in 1944 delivered 17% of Japan's combat airframes and 12% of its combat engines. Against Akashi, Hansell sent 77 B-29s, plus 3 others in a diversionary strike. With good weather, 62 bulled it through to the Kawasaki factory, dumped 155 tons of GPs, and then returned with no losses. Interpreting strike photos, intelligence officers estimated that 38% of the roofed area showed major damage. This was an understatement. Every important building in both the engine and airframe branches had been hit and production was cut by 90%. Indeed, the Kawasaki Company liquidated the combined plant and dispersed the machine tools, which had suffered only slightly, to other sites. The Akashi shops were given temporary repairs at the cost of 226 tons of critical materials and over 9000000 yen, but the installation was used thereafter only for limited assembly jobs. It is a pity that the full results of this mission could not have been known to Hansell. His first completely successful B-29 attack, Akashi seemed to epitomize the doctrines of precision bombardment he had championed-and it was his last strike of the war. Unaware of this success, Hansell was replaced the following day as head of the 21st Bomber Command by the determined LeMay, who immediately suggested a shift to firebombing Japan's major cities at low altitude during nighttime, marking a stark departure from Hansell’s previous strategies. However, the only obstacle in the flight path was Iwo Jima, which could alert the Japanese to an impending raid and still had operational airfields capable of launching intercepting fighters. These airfields had also been used for sporadic air assaults on the Marianas, although few attacks were actually carried out in January.

Capturing Iwo Jima would resolve these issues, and Admiral Nimitz aimed to establish emergency landing facilities for B-29s based in Saipan, as well as a base for their fighter escorts targeting Japan. Consequently, he decided to proceed with the invasion, codenamed Operation Detachment. After this operation, Nimitz planned to invade Okinawa to secure and develop a robust air and naval base for the assault on the Japanese home islands, which we will discuss further later. For the Iwo Jima operation, Admiral Spruance was once again given overall command of the "big blue fleet," which was re-designated as the 5th Fleet. Under his command, Vice-Admiral Richmond Turner led Task Force 51, the Joint Expeditionary Force, responsible for landing Lieutenant-General Holland Smith’s Expeditionary Troops. Turner was supported by Rear-Admiral William Blandy’s Task Force 52, the Amphibious Support Force, which included ten escort carriers; Rear-Admiral Harry Hill’s Task Force 53, comprising all transports and landing craft; Rear-Admiral Bertram Rodgers’ Task Force 54, which had six battleships and five cruisers for shore bombardment; and Vice-Admiral Marc Mitscher’s Task Force 58, the Fast Carrier Force. For the amphibious invasion, Major-General Harry Schmidt’s 5th Amphibious Corps would deploy the 3rd, 4th, and 5th Marine Divisions, planning to land the 4th and 5th Divisions side by side with two regiments each along the two-mile stretch of beach between Mount Suribachi and the East Boat Basin on the island's southeast coast. Smith and Schmidt also decided to limit corps artillery to two battalions of 155mm howitzers, organized as the 1st Provisional Field Artillery Group, due to the limited space available for emplacements on the island.

After landing, Major-General Clifton Cates’ 4th Marine Division would take control of the Motoyama Plateau and its airfields, while also capturing the O-1 Line on the corps’ right flank. Meanwhile, Major-General Keller Rockey’s 5th Marine Division would secure the Mount Suribachi region before advancing northeast to capture the O-1 Line on the corps’ left flank. They would then push forward across the island until Iwo Jima was fully secured. At the same time, Major-General Graves Erskine’s 3rd Marine Division would remain in reserve, with only its 21st Marine Regiment deployed as the corps reserve. To aid in this effort, the 7th Air Force, under Generals Harmon and Hale, had been consistently targeting Iwo Jima’s facilities since August 1944. Following intense attacks in December, which included bombardments by Rear-Admiral Allan Smith’s 5th Cruiser Division against Iwo Jima, Haha Jima, and Chichi Jima were again struck on January 5, but the next bombardment wouldn’t occur until January 25. 

A fighter sweep by 28 P-38s opened the attack at 0945; 62 B-29s bombed at 1100 and 102 B-24s at noon; Crudiv 5 (Rear Admiral Allan E. Smith), comprising heavy cruisers Chester, Pensecola and Salt Lake City with six destroyers, arrived off Iwo at 1330 and opened bombardment at 1347. "Hoke" Smith approached the island from the west, rounded Mount Suribachi and then reversed track in a half-circle. Unfortunately the sky was so heavily overcast as to force the planes to bomb by radar and to hamper ships' spotting. Surface visibility was good enough to enable the island to be well covered by a naval bombardment, which lasted for 70 minutes and expended 1500 rounds of 8-inch and 5334 rounds of 5-inch shell. The bombers dropped 814 tons of bombs. Photographs, taken three days later, showed that both airfields on Iwo were wholly or in part operational, but no more enemy air raids hit the Marianas until Christmas Day. The job of keeping Iwo airfields neutralized was now turned over to B-24s of VII A.A.F. Between 8 December 1944 and 15 February 1945 they flew at least one strike daily over the island. The day before Christmas, Rear Admiral Smith's heavy cruisers, together with five destroyers, delivered a second bombardment, coordinated with a B-24 strike. This strike was slightly more eventful than the initial one in December, but even less effective. The bombardment, which expended 1500 rounds of 8-inch, provoked return fire from a 6-inch coast defense battery (designated "Kitty" on the target maps) in the northeast part of the island, but "Kitty's" claws managed to strike no closer than 200 yards. As proof of the slight damage inflicted by this bombardment, the Japanese were able to pay a vicious return visit to Saipan on Christmas Eve, a raid of 25 planes which destroyed one B-29 and damaged three more beyond repair.

Crudiv 5 returned 27 December for a repeat performance, lighter than the others; and a fourth bombardment was set up for 5 January 1945. While fighter planes and B-24s hit Iwo Jima the same cruisers and six destroyers bombarded Chichi Jima, 145 northward, and the slightly nearer Haha Jima. Their hope was to catch a convoy bringing Japanese supplies to these islands, whence they were forwarded to Iwo by small craft at night. Destroyer Fanning, steaming ahead of the group as radar picket, encountered at 0206 a surface target, later identified as LSV-102, which she sank. At 0700 Admiral Smith's group opened a one hour and 49 minutes' bombardment of Chichi Jima. During it, destroyer David W. Taylor suffered an underwater explosion, probably from a mine, which flooded her forward magazine. The Haha Jima bombardment by Salt Lake City and two destroyers lasted for an hour. Crudiv 5 then pounded Iwo Jima for another hour and three quarters. The reply was negligible, and a few aircraft which made passes at the cruisers were easily driven off.

Starting on the last day of January and continuing for two weeks, 7th Air Force aircraft bombed the island day and night, occasionally joined by LeMay’s Superfortresses. For ten weeks, Iwo Jima faced near-daily bombardments from land-based aircraft, with nearly 6,800 tons of bombs dropped. Additionally, there were five naval bombardments that fired 203 rounds of 16-inch shells, 6,472 rounds of 8-inch shells, and 15,251 rounds of 5-inch shells. Under normal circumstances, such a heavy and sustained bombardment would have been more than enough to devastate an island of that size. However, the Japanese managed to restore the airfields on Iwo Jima just hours after each attack and continued to strengthen their defenses on the island.

Following the fall of Saipan, the Japanese appointed Lieutenant-General Kuribayashi Tadamichi to oversee the defenses of the Bonin Islands, renaming the Ogasawara District Group as the 109th Division. Kuribayashi stationed Major-General Tachibana Yoshio’s 1st Mixed Brigade and most of Colonel Iida Yusuke’s 17th Independent Mixed Regiment on Chichi Jima, along with several other units across the islands. He accurately predicted that Iwo Jima would be the target for an Allied landing and took measures to make it virtually indestructible. To this end, he coordinated with Major-General Senda Sadasue’s 2nd Mixed Brigade, Colonel Ikeda Masuo’s 145th Regiment, and Lieutenant-Colonel Baron Nishi Takeishi’s severely weakened 26th Tank Regiment, which had sustained heavy losses from American submarines at sea. Additionally, Major Fujiwara Tamachi’s 3rd Battalion of the 17th Independent Mixed Regiment and a robust artillery unit led by Colonel Kaido Chosaku were included in the defense. Rear-Admiral Ichimaru Toshinosuke also provided a significant naval garrison on the island, centered around the 27th Air Flotilla, bringing Kuribayashi’s total forces to approximately 21,060 men, far exceeding the American estimate of 13,000. Aware that the beaches would be vulnerable to enemy naval and air assaults, Kuribayashi opted to strengthen the Mount Suribachi and Motoyama Plateau areas.

The Mount Suribachi area was made a semi-independent defense sector, its heavily fortified positions bristling with weapons of all types, ranging from casemated coast-defense guns and artillery to automatic weapons emplaced in mutually supporting pillboxes. The narrow isthmus connecting Suribachi to the rest of the island was lightly held by infantry, but heavily defended by enfilade fire from artillery, rockets, and mortars emplaced on both the high ground in the south (Suribachi area) and the northern portion of the island. The main defense line was a belt of mutually supporting positions organized in depth, running generally northwest-southeast across the island. It stretched from the cliffs north of the western beaches south to include Airfield Number 2; then, turning eastward through Minami, terminated at the rugged coast north of the eastern beaches. Pillboxes, blockhouses, bunkers, and dug-in tanks strengthened the defenses in the naturally formidable terrain everywhere throughout this belt. The second defense line generally bisected the remaining area in the northern portion of the island. It began several hundred yards below Kitano Point on the northwest coast, cut through Airfield Number 3 and the Motoyama area in the center, and terminated between Tachiiwa Point and the East Boat Basin on the eastern coast. Man-made emplacements were not as numerous in this second line, but natural caves and other covered positions afforded by the fantastically rugged terrain were skillfully organized for the defense. The beaches would be lightly defended but would receive fire support from the elevated positions. A substantial reserve force, including tanks, was also prepared to counterattack and push the Americans back into the sea if they managed to establish a foothold. In a shift from traditional Japanese defensive strategies, Kuribayashi moved away from full-scale counterattacks and suicidal banzai charges, instead instructing his troops to hold their mutually supportive positions to the last and to carry out small unit counterattacks at cutoff points.

The Allied forces continued their advance through Luzon, battling Japanese defenses, liberating prisoners, and securing key locations, paving the way for a final push toward Manila. Meanwhile, on Iwo Jima, General Kuribayashi was preparing for a final stand, hoping beyond hope to make the Americans pay so dearly they might end the war.

- 166 - Pacific War Podcast - the Mandalay Offensive - January 21 - 28 , 1945

Last time we spoke about the South China Sea Raid. In January, General Krueger reinforced the American beachhead at Lingayen Gulf while Admiral Halsey launched Operation Gratitude, targeting enemy ships based on faulty intelligence. Despite not finding the expected battleships, American forces decimated a Japanese convoy, sinking numerous vessels and claiming 113 enemy aircraft. Meanwhile, on Luzon, the 1st and 14th Corps advanced against Japanese defenses, capturing key positions despite fierce resistance. As both sides prepared for counteroffensives, the battle intensified, marking a pivotal moment in the Philippines campaign. On January 17, the 58th Brigade and supporting regiments launched a daring operation to destroy enemy positions. As American forces advanced, they faced fierce resistance, but some regiments achieved notable successes. Task Force 38 executed airstrikes on Formosa and Hong Kong, inflicting damage despite heavy losses. Meanwhile, Japanese forces struggled to regroup amid American pressure. General Suzuki devised a plan to fortify Leyte, but ongoing air raids hampered supply efforts. Tensions escalated as both sides prepared for decisive confrontations in the ongoing battle for control.

This episode is the Mandalay Offensive

We last left off with, General Krueger strategically positioned General Mullins’ 25th Division on the right flank of the 43rd Division to bolster the assault forces at the Rosario front. This maneuver was also intended to facilitate the continuation of the 14th Corps’ advance to the south. Following the successful repulsion of General Nishiyama’s local counterattack, General Wing ordered the 63rd, 158th, and 172nd Regiments, which had been stalled, to launch an offensive from the west along the Damortis-Rosario road. Simultaneously, the 103rd and 169th Regiments were tasked with advancing northward along Route 3, originating from Pozorrubio. In contrast, while the 58th Independent Mixed Brigade and the 23rd Division worked to contain General Swift’s 1st Corps, General Yamashita was reinforcing the San Jose sector. He further instructed the Shigemi Detachment to maintain a defensive position in Binalonan. Although the 27th and 161st Regiments had successfully relieved the 103rd Regiment in the Binalonan area, Major-General Shigemi Isao ultimately opted to halt further troop movements. He decided to leave only a small garrison in Binalonan while the majority of his forces prepared for a decisive stand at San Manuel.

 

As the situation unfolded, the 3rd Battalion of the 161st Regiment encountered minimal resistance, allowing them to advance into the northern half of Binalonan by nightfall on January 17. In a parallel effort, General Patrick directed the 1st Regiment towards Urdaneta, where they successfully eliminated a small outpost belonging to the Shigemi Detachment. Additionally, he dispatched the 20th Regiment to the Cabaruan Hills, where they achieved their objective by reaching Lunec and securing the central area of the hills by the end of the day. On January 18, the offensive momentum of the 6th and 25th Divisions persisted. The 20th Regiment advanced to a low ridge approximately 2,500 yards west of Cabaruan, where American forces identified the primary defenses of the 2nd Battalion, 71st Regiment. Meanwhile, the 161st Regiment successfully cleared Binalonan, and the 27th Regiment moved forward to seize control of the Bactad area, further consolidating their gains in the region.

Simultaneously, Wing's units were gearing up for a significant new offensive. In line with this strategy, the 2nd Battalion of the 169th Regiment advanced along Route 3, deftly circumventing the town of Sison, and finally reached a crucial road junction located to the northeast of the town. Meanwhile, to the north, the 172nd Regiment executed a successful nighttime ambush against a Japanese artillery battalion. Following this victory, they dispatched a company to seize control of a strategically important hill, rising 600 feet and situated approximately 1,000 yards north of Rosario. This position enabled American forces to exert control over a substantial portion of the surrounding area. By the conclusion of the day, the 158th and 63rd Regiments established contact through patrols about a mile south of Amlang, as they prepared for a coordinated assault that was set to launch on January 19. This offensive culminated in the collapse of the last Japanese defenses just two days later. Concurrently, the 172nd Regiment successfully established a patrol base on Hill 606. From this vantage point, patrols ventured into Rosario, discovering the town was heavily mined, riddled with booby traps, and defended by concealed machine-gunners and riflemen hiding amidst the rubble of the buildings.

On January 19, the 103rd Regiment initiated an assault on Hill 600, located at the southern end of the ridge line east of Route 3. At the same time, the 2nd Battalion of the 169th Regiment faced several intense counterattacks from retreating Japanese forces that had been bypassed at Mount Alava and Sison. Despite the fierce resistance, the relentless pressure from Japanese troops and increasingly heavy artillery fire ultimately compelled the battalion to withdraw by noon. Nevertheless, the American operations succeeded in diminishing the Japanese presence in the region. Looking southward, the 161st Regiment cautiously advanced toward San Manuel, while the 27th Regiment effectively moved into Asingan, successfully cutting off Shigemi’s escape route. Further south, the 1st Regiment rapidly progressed along Route 3 toward the Agno River, capturing the towns of Villasis, Carmen, and Rosales. Meanwhile, the 20th Regiment commenced an assault on the 2nd Battalion of the 71st Regiment stationed in the Cabaruan Hills.

On the front commanded by General Griswold, the 14th Corps was in the process of mobilizing along the Camiling-Anao line, preparing to initiate an advance toward the Tarlac-Victoria line. The 160th Regiment began its march, covering seven miles southward from Camiling along Route 13, while the 129th Regiment took a strong position in Anao, establishing vital contact with other outposts of the 37th Division stationed at Paniqui. The advances made on January 20 were notably swift, with the 148th Regiment successfully capturing the towns of Gerona and Pura. Meanwhile, the 37th Reconnaissance Troop made significant progress by entering the guerrilla-occupied area of Victoria, and units from the 40th Division advanced to within four miles of Tarlac, signaling a promising push toward their objectives.

In the area around Cabaruan, the Japanese forces had sustained heavy losses during the initial attack. In response, Colonel Patrick made the strategic decision to withdraw two battalions from the hills to reinforce the southern advance. Probing slowly through the roughest ground in the Cabaruan Hills on January 20 and 21, the 20th Regiment's reinforced battalion jumped off in the morning of the 22nd in what was expected to be the last attack, its way paved by an especially heavy artillery and air bombardment. But from the start, operations did not go as planned. The air strike, conducted by Fifth Air Force A-20s was four hours late, subjecting the infantry to "a nerve racking wait," and did not include requested napalm. Air and artillery concentrations were, however, well placed, and it seemed improbable to the waiting infantry that many Japanese could have lived through them. A combined tank-infantry assault began about 12:30 and proceeded slowly but steadily for almost two hours. Then the attackers were stopped cold by a tremendous burst of rifle, machine-gun, and light artillery fire from the very hillsides that had received the weight of the bombardments. Company E, in the lead, fell back; Company G's officers were all either killed or wounded, and the company was temporarily scattered; Company F was pinned in place; and two supporting tanks were knocked out. Casualties mounted quickly to 10 men killed and 35 wounded.

As a consequence, Patrick found it necessary to redirect one battalion from the 1st Regiment to support the ongoing attack. Simultaneously, the remainder of the 20th Regiment pressed forward toward Cuyapo, while the bulk of the 1st Regiment continued its eastward movement toward the guerrilla-held Balungao. Additionally, the 6th Reconnaissance Troop reached Guimba, successfully establishing contact with patrols from the 14th Corps, which was crucial for coordinating their efforts. On another front, with Mount Alava now vulnerable, the 169th Regiment launched a vigorous assault on January 20, managing to secure the summit of the mountain by nightfall. In contrast, the 103rd Regiment continued to face heavy casualties during their frontal assaults against Hill 600, ultimately gaining only a precarious foothold on the exposed southern slopes. Meanwhile, in a significant naval development, Admiral Halsey’s Task Force 38 exited the South China Sea through the Balintang Channel on January 20. The task force was poised to execute further strikes against Formosa, aiming to disrupt enemy operations and bolster the Allied offensive in the region.

The following day, with significantly improved weather conditions, Admiral McCain’s aircraft carriers launched a coordinated series of airstrikes targeting Formosa, the Pescadores Islands, and the southern Ryukyu Islands. These operations resulted in the destruction of 104 Japanese aircraft on the ground, the sinking of seven oil tankers, and the loss of seven transport ships, along with additional damage inflicted on another seven vessels. 

For the first time since November 1944, TF 38 felt the sting of kamikazes. Operating just 100nm east of Formosa, TF 38 was not difficult to find. Just after noon, a single aircraft appeared to conduct a conventional bombing attack on TG 38.3’s light carrier Langley. One bomb hit forward. Personnel casualties were light, but the carrier was conducting flight operations three hours later. Within minutes, another aircraft also evaded radar detection and the CAP to commence a suicide dive against Ticonderoga. The kamikaze struck the flight deck and penetrated where its bomb exploded. An impending strike was spotted and ready to launch; now these aircraft provided fuel for the fire which was quickly spreading. Just before 1300hrs, another group of eight kamikazes and five escorts resumed the attack on TG 38.3. Only two suicide aircraft survived the CAP to dive on the wounded Ticonderoga. One was sent spinning into the water by antiaircraft fire, but the final attacker crashed into the carrier’s island. More fires were started. The crew succeeded in putting out the flames by 1415hrs and correcting a nine-degree list by 1800hrs. Though the ship was saved, the cost was high. Some 143 men were killed and 202, including her captain, were wounded. In addition, the air group lost 36 aircraft. As a final farewell, kamikazes attacked the two destroyers on picket duty just 65nm off Formosa at 1310hrs. A single Zero had joined a returning strike. Before it could be identified as enemy, it dove on destroyer Maddox, striking her amidships. This and the explosion of the bomb aboard created a fire that was quickly extinguished. After a final day of strikes on January 22 against the Ryukyus, during which eight ships were sunk, Task Force 38 set course for Ulithi. Upon arrival, Admiral Halsey transferred command of the Fast Carrier Force to Admiral Spruance, who would lead the final offensives in the Central Pacific. 

Meanwhile, back on Luzon, on January 21, the 160th Regiment swiftly cleared the town of Tarlac and began its advance toward San Miguel. Simultaneously, the 145th and 148th Regiments moved unopposed toward La Paz. The speed of 14th Corps' advance had stretched Griswold’s supply lines abnormally and had exposed his left from Cuyapo to La Paz, a distance of nearly 25 miles. He had no definite information about suspected Japanese concentrations in the vicinity of Cabanatuan, on Route 5 just 15 miles east of La Paz. His worries about the security of his flank were hardly put to rest by reports of new contacts with Japanese forces at Moncada, now 20 miles behind the front, and at La Paz. Elements of the 129th and 145th Regiments easily took care of the Japanese in the Moncada area; but during the night of January 21, a pitched battle developed at La Paz when a platoon of Japanese infantry, supported by one tank, attacked a 148th Regiment perimeter at a road junction a mile west of town. The Japanese finally withdrew after destroying a bridge that carried a secondary road across a river a mile east of La Paz; but because of this, Griswold reported to General Krueger that it would be impossible to extend 14th Corps' left any further south until he had more information about Japanese forces east of La Paz. To mitigate this risk, he decided to keep General Beightler’s 37th Division positioned in reserve while General Brush’s 40th Division continued its advance southward along Route 3 toward Bamban.

As a result, elements of the 160th Regiment and the 40th Reconnaissance Troop reached Capas and conducted patrols toward Camp O'Donnell on January 22. Meanwhile, the 161st Regiment began probing the defenses established by Japanese forces under Shigemi. The 103rd Regiment faced severe losses during their assault on Hill 600, necessitating a withdrawal to reorganize. Concurrently, the 169th Regiment launched an attack on Hill 355, making slow and costly progress against fierce resistance on the steep, barren slopes. By January 24, most of Hill 355 had been cleared, allowing the 3rd Battalion of the 103rd Regiment to move in and conduct mop-up operations in the area.

As the 158th Regiment looked northward and secured the area around Amlang, they initiated an eastward push towards the positions held by the 172nd Regiment. However, their advance was slow, with only a modest gain of 500 yards achieved. Over the next two days, the 158th faced a grueling battle, making painstaking progress as they advanced foot by foot across exposed hills and ridges, all while enduring relentless machine-gun, mortar, and artillery fire. It wasn't until January 26 that they successfully broke through to Cataguintingan, where they provided much-needed support to the 172nd Regiment's ongoing assaults into Rosario. Meanwhile, by the evening of January 23, the 161st Regiment had managed to secure the southern slopes of the barren ridge north of San Manuel. They established trail blocks in the Aboredo Valley, effectively controlling movement in the area. To the south, the 108th Regiment had taken control of the Capas region, while the 160th Regiment successfully captured Bamban. However, it became increasingly evident that the American forces were now confronting the well-fortified and organized defenses of the Kembu Group.

The Kembu Group's strength lay in the terrain it held, in the depth of its defenses, and in the great number of automatic weapons (aircraft and anti-aircraft) it possessed. Its major weaknesses were its immobility; the inadequate training and armament of the bulk of its troops; shortages of food, ammunition, and field artillery; and the rudimentary state of many defensive installations, a state deriving from the late start in establishing the positions at and west of Clark Field. The health of the command was poor from the start, and medical supplies were short. Morale was not of the highest order, and many of the troops were easily disaffected Formosan, Okinawan, and Korean labor personnel. In brief, the Kembu Group was the poorest armed, prepared, and supplied of Yamashita's three defense commands. On the other hand, as the 40th Division was soon to learn, even poor service troops, whatever their state of training and armament, can put up stiff resistance in good defensive terrain. 

In preparation for the defense of Clark Field, General Tsukada assembled a diverse array of forces, totaling approximately 30,000 troops, although the majority consisted of air and naval personnel. He strategically divided his Army units into four distinct detachments. The Takayama, Takaya, and Eguchi Detachments were positioned along the first and second lines of defense, facing eastward toward Highway 3. Their defensive line extended from the hills west of Bamban to the vicinity of Fort Stotsenburg. In contrast, the Yanagimoto Detachment maintained its mobile units at Angeles and Porac, ready to respond to any potential enemy paratrooper landings on the southern flank of the Clark Field defenses.

Additionally, Rear-Admiral Sugimoto Ushie commanded naval units comprising about 15,000 men, tasked with defending positions behind the two forward lines. In light of this formidable opposition, General Griswold made the strategic decision to utilize January 24 for consolidation and regrouping. This involved preparing for further advances southward while also probing into the enemy defenses that had already been uncovered. The 160th Regiment was able to secure Lafe Hill, although they were unable to establish a foothold on Hill 500, highlighting the challenges that lay ahead. To the north, American forces initiated another offensive against the Cabaruan Hills. The units of the 1st Regiment made only modest progress, yet they managed to advance closer to the main defensive positions as night fell. Meanwhile, at San Manuel, the 161st Regiment launched its first assault against the Shigemi Detachment, which encountered unexpectedly fierce resistance. As a result, the Americans were only able to establish a fragile foothold in the northern section of the town.

Further north, Wing directed the 103rd Regiment to set up a line of departure along Route 3, aiming to strike eastward at the northwestern slopes of Hill 600. At the same time, they were tasked with advancing up the southwestern slopes of the exposed Hill 700 to secure that strategic location, as well as Hill 800 to the northwest. The 169th Regiment, advancing to the left of the 103rd, was assigned to capture Question Mark Hill. Concurrently, the 63rd and 172nd Regiments were ordered to launch simultaneous assaults on Hills 900 and 1500, respectively, while the reserve 3rd Battalion of the 63rd Regiment was also committed to clear Benchmark Hill. This coordinated attack was scheduled for January 25. The initial phases of the assault showed promise, with the supporting forces making significant headway. However, the 103rd Regiment faced considerable difficulties, managing to secure Hill 800 only by nightfall. Notably, the 172nd Regiment achieved tactical surprise, successfully clearing most of Hill 900. Over the next two days, the 63rd Regiment regrouped around Hill 1500 in preparation for its own offensive.

Simultaneously, the 161st Regiment continued its slow advance southward through San Manuel, facing intense opposition. Patrick's units on the Cabaruan Hills managed to gain a mere 300 yards against determined resistance. Meanwhile, Brush pressed his attack on Clark Field, with the 160th Regiment clearing Hill 500 and advancing nearly a mile along the ridge from Lafe Hill, while the 108th Regiment secured Hills E and G. The following day, the 40th Division continued its southward maneuver. Any movement by American troops along the generally open ridges west of Route 3 inevitably brought down Japanese machine-gun and mortar fire, often augmented by fire from the dismounted aircraft automatic weapons, anti-aircraft guns, and light artillery. Seeking cover and usually pinned in place, the American infantry would call for close-in mortar and artillery support, wait for the concentrations to be fired, and then drive forward a few yards, when the process had to be repeated. Each time, the Americans managed to overrun a few Japanese machine-gun or rifle strongpoints. There was little choice of routes of advance. Draws, providing some concealment in scrub growth or bamboo thickets, were usually covered by well-emplaced Japanese weapons both within the draws and on the ridges to each side. Possession of the high ground, as ever, was essential. Yet the troops had to employ draws whenever possible to outflank Japanese ridgeline strongpoints, and often draws and ravines proved to be the only routes by which tanks, tank destroyers, and cannon company self-propelled mounts could get to the front to fire against Japanese cave positions along the sides of the ridges. The capture of one Japanese-held cave served only to disclose another, and one machine-gun position was overrun only to provide access to the next. Dislodging the Kembu Group from such defenses in depth was to prove a slow, laborious, and costly process, demanding the closest teamwork between the infantry and its supporting arms. Casualties, as a rule, would not be heavy on any one day--progress would be too slow and the troops would spend too much of their time pinned down awaiting fire from supporting weapons. But a daily attrition rate of about 5 men killed and 15 wounded for each battalion engaged would soon begin to have its effect.

Meanwhile the 160th Regiment swiftly captured Hills 636 and 600 in rapid succession. However, the 108th Regiment lost control of Hill G during the engagement. On January 26, Griswold committed the 37th Division to the fight, with the 145th Regiment successfully capturing Mabalacat and Mabalacat East Airfield. They then shifted westward across Route 3, overrunning Clark Field Runway Number 1. In the Cabaruan Hills, American forces gained only 150 yards at a considerable cost. In response, Patrick decided to deploy another battalion from the 1st Regiment to eliminate this pocket of resistance. The following day, this two-battalion assault proved successful, resulting in the destruction of an entire battalion of Japanese troops, with over 1,400 enemy soldiers killed. Further north, the 161st Regiment finally broke through the main defenses of Shigemi’s forces. Before dawn most of the Japanese left in San Manuel scrambled across the draw on the east side of town and fled to join the 10th Reconnaissance Regiment north of San Nicolas, but not before launching a final counterattack to cover their escape. At 0930 the 161st Infantry's two battalions resumed the drive southward through the town, and by 1330 San Manuel was clear. In a heroic but tactically unimportant stand the Shigemi Detachment had virtually fulfilled its self-imposed desire for annihilation in place. The detachment had lost 750 men killed; all its tanks, artillery, trucks, machine guns, and mortars had been either captured or destroyed. Probably no more than 250 troops escaped, and many of them were unarmed and wounded. The 161st Infantry and attached units had lost approximately 60 men killed and 200 wounded; the 716th Tank Battalion lost 3 tanks.

Meanwhile, Wing's offensive continued on January 27, with the 103rd Regiment successfully reaching the crest of Hill 700 and the northwestern slopes of Hill 600. Unfortunately, they lost both positions to a brutal Japanese counterattack amidst a violent tropical downpour. On January 28, the 172nd Regiment captured Rosario, while the 63rd secured the southern crest of Hill 1500. Both regiments completed the capture of this strategic feature by January 30, thereby finalizing the occupation of the crucial road junction area. Further south, on January 27, the 160th Regiment advanced only 500 to 800 yards to the west and southwest. The 108th Regiment made a more substantial advance of about 1,000 yards southwest from Hills E and G but failed to reach Hill 5. The 145th Regiment pushed south along Route 3 for an additional three miles, reaching Culayo and Dau before taking control of the guerrilla-occupied Angeles, which had recently been abandoned by the retreating Yanagimoto Detachment. In a similar vein, the 148th Regiment secured Magalang without encountering any resistance.

As we shift our focus from Luzon, we turn our attention to Burma, where we will delve into the ongoing developments of Operation Capital. Picking up from our previous discussions, we find ourselves in Central Burma, where the 2nd British Division and the 19th Indian Division are making significant strides toward Shwebo. The 2nd British Division successfully captured Ye-u on January 2, followed by the establishment of a crucial bridgehead across the Mu River just three days later. Meanwhile, the 19th Indian Division also advanced, reaching the Shwebo area by January 5.

On January 8, a coordinated assault was launched by units from both divisions, culminating in the capture of Shwebo after two days of intense and brutal combat. To the west, General Festing’s 29th Brigade began probing the northern flank of the 15th Division at Twinnge. Concurrently, other elements of the 19th Division worked to solidify their positions by establishing additional bridgeheads over the Irrawaddy River at Thabeikkyin and Kyaukyaung. On January 10, the 20th Indian Division captured Budalin and subsequently pushed towards Monywa, where the 33rd Division had only left a small contingent to serve as a rearguard. However, the campaign faced unexpected challenges; heavy rainfall during the first week of January brought all transport operations of the 4th Corps to a standstill, significantly hampering the Lushai Brigade's planned assault on Gangaw.

After enduring a heavy aerial bombardment, the attack on Gangaw finally commenced on January 10. The Lushai Brigade managed to overpower the limited defending forces, forcing them to retreat after a brief skirmish. With Gangaw now under their control, the Lushai Brigade refocused their efforts on reconnaissance, monitoring the flanks of the 7th Indian Division. Meanwhile, the 28th East African Brigade took the lead in the advance, successfully displacing a Japanese garrison at Tilin on January 22. By this time, the 114th Brigade had begun to follow in the wake of the East Africans, while the 89th Brigade executed a long maneuver to the left, advancing toward Pauk in parallel with the other offensives. Although General Kimura was aware of some movements on his southern flank, he perceived these as mere feints by minor forces intended to divert his attention southward.

Following a relentless barrage of artillery and air strikes, the 20th Division launched its offensive against Monywa on January 20. This assault faced fierce resistance, and it took two days of intense and bloody combat before the division was able to secure control of the town. After capturing Monywa, the 80th Brigade advanced towards Myaung, while the 110th Brigade shifted its focus to Ayadaw before launching an attack on Myinmu. By January 25, they had successfully established a bridgehead in that area. Meanwhile, to the east, the 2nd Division commenced its assault on Sagaing on January 14. They made significant headway against the forward defenses of the 31st Division, with other units managing to secure a bridgehead at Ywathitgyi. General Katamura, concerned about the expanding bridgeheads established by the 19th Division across the Irrawaddy River, ordered the 15th and 53rd Divisions to neutralize these positions before they could become fortified.

As a result, during the last week of January, the Japanese forces executed a series of coordinated night attacks on Kyaukmyaung. By this time, British-Indian troops had dug in deeply, supported by formidable artillery and machine-gun positions. The ensuing conflict was marked by brutal carnage, with the 15th Division suffering a staggering loss of one-third of its personnel, while the 53rd Division was compelled to withdraw to Kyaukse after incurring heavy casualties. In parallel, the 89th Brigade successfully occupied Pauk on January 28, as General Messervy’s forces geared up for a decisive push towards Meiktila. Looking northward, General Sultan was also advancing his own offensive aimed at reopening the Burma Road to China. He ordered the 50th Chinese Division to move towards Lashio and deployed the Mars Task Force to Hosi. Additionally, he dispatched the 36th British Division towards Mongmit, although the British advance was expected to be slow until additional forces could be brought into alignment for a more coordinated effort.

General Sun’s newly established 1st Army initiated a delayed offensive against Namhkam, which resumed in early January. This resurgence was marked by the 90th Regiment's strategic capture of the hill that overlooks the southwestern entrance to the Shweli River valley. Concurrently, the 112th Regiment advanced through Loiwing, subsequently crossing the river to approach Namhkam from the northeast. Meanwhile, the 88th Regiment entered the valley via the main road, making a direct push across the small plain toward Namhkam. The 89th and 114th Regiments executed a broader maneuver around the southern end of the Shweli valley; the 89th crossed the river on January 7 and advanced northward toward Namhkam, while the 114th crossed three days later, navigating through the hills toward the Namhkam-Namhpakka trail.

To the south, the 475th Regiment progressed through Mong Hkak and reached Mong Wi on January 6, preparing for another challenging march across the hilly terrain toward Hosi, with the 124th Cavalry Regiment following closely behind. So close is Tonkwa to the mountains that the 475th found the trail rising steeply on the 1st day's march east. Like a crazily twisted drill it bored its way farther east and ever higher. In some places it was 15 to 20 feet across; in others, just wide enough for a man and a mule. As they rounded the turns, the men would peer ahead and look out across the valleys to where lay row on row of hills. Trees were everywhere. In flat places carved by erosion, the Burmese had cut and farmed terraces, and little villages clung to the mountains like limpets to a rock. Because existing maps were unreliable, so that map reconnaissance could not locate water and bivouac areas, and because the sheer fatigue of climbing the steeper slopes was formidable, march schedules went down the mountain side, with quite a few steel helmets and an occasional mule. Halts were a matter of common sense leadership at platoon or company level. The march was tactical but no Japanese were encountered, though rumor of their nearness kept the men alert. The Chinese had passed that way before, while a screen of Kachin Rangers was preceding the American column. Speaking the local dialects and carrying radios and automatic weapons, the Kachins were an excellent screen which masked the MARS Task Force while reporting anything that might be suspicious. Despite the difficult march, crossing the 400-foot wide Shweli was not too hard. The bridge built by the Chinese some weeks before still stood, a triumph of Oriental ingenuity, with bundles of bamboo for pontons and vines for cable. The Shweli was beginning to tear it apart, but work parties from the 475th kept it operable. 

Meanwhile, spurred into action by General Wedemeyer after a month of inactivity, General Wei’s Y-Force finally resumed its offensive operations in late December. They promptly dispatched the 2nd, 6th, and 71st Armies to launch an assault on the forward positions of the 56th Division at Wanting. Simultaneously, the 53rd Army executed a wide flanking maneuver to the west, aiming to encircle and attack the Japanese forces from the rear. Faced with the intense pressure of this four-pronged offensive, General Matsuyama was compelled to withdraw the 148th Regiment to a position north of Mongyu. He also ordered the Yoshida Force to mount a counteroffensive toward Muse and committed the reserve 2nd Regiment to secure Namhpakka. On January 5, the 53rd Army reached the vicinity of Muse and began crossing the river; however, they were met with fierce resistance from Matsuyama's timely counterattack, which thwarted their advance.

Ten days later, Sun’s forces initiated a well-coordinated offensive against Namhkam, which ultimately succumbed on January 16 as the 55th Regiment retreated toward Khonung. With the Shweli Valley now firmly under Allied control, Matsuyama began to tighten his defensive perimeter in anticipation of a final withdrawal toward Hsenwi. On January 17, the Mars Task Force made significant progress by reaching the Hosi sector, where they immediately engaged Japanese outposts. The 475th Regiment successfully secured the advantageous high ground near Nawhkam village. Over the next two days, American forces clashed with the 4th Regiment, capturing the strategically important Loikang Ridge and the elevated terrain overlooking Namhpakka. On January 19, the Mars Task Force attempted to disrupt Japanese supply lines by blocking the Burma Road through demolition and artillery bombardment, coinciding with the arrival of the 55th Regiment, which was sent to bolster the defenders. In a parallel effort, the 114th Regiment managed to sever the Namhkam-Namhpakka trail at Loilawn on the same day.

Faced with this escalating threat from the south and the intensifying Chinese assaults on Wanting, the 56th Division was compelled to further contract its defensive perimeter. As a result, Wanting fell on January 20. Fortunately for Matsuyama, General Wei received orders from the Generalissimo to conclude the Salween campaign immediately, which meant that the Chinese forces would remain in their positions until they could be relieved by Sultan’s units. Over the course of nearly nine months of intense combat, Wei’s Y-Force had successfully reoccupied an impressive 24,000 square miles of Chinese territory and had defeated one of the most elite divisions of the Japanese army, along with elements from two additional divisions. However, the fighting was far from over. Sun continued to dispatch the 112th and 113th Regiments toward Wanting and Mongyu, aiming to clear the final stretch of the road leading to China. Meanwhile, the 89th and 114th Regiments pressed eastward to cut off the Burma Road north of Namhpakka, further complicating the situation for the Japanese forces.

In the southern region, from January 20 to January 24, the Mars Task Force continued its strategic operations, executing ambushes and demolition missions while successfully repelling several intense counterattacks from enemy forces. By late January, pressure by MARS Task Force and that of the Chinese forces in the north began to register on the Japanese. The soldiers of the 4th Regiment could see the aerial activity that kept MARS supplied. Not recognizing what they saw, they were so impressed by a big supply drop on the 24th that they sent a report to the 56th Division of a large airborne force being landed along the Burma Road. Accepting this report, General Matsuyama decided to destroy his ammunition and retreat south. His superiors on January 24 agreed to let him retreat, but only after he had evacuated casualties and ammunition. Forty vehicles with gasoline accompanied by a Major Kibino of the 33rd Army staff were sent north to support the 56th in its withdrawal. The Japanese truck convoy made its run north the night of January 24. The trucks were heard, and the Americans placed heavy fire on the road. Kibino had been making the trip in a tankette. Hit by a 4.2-inch mortar shell, it burst into flames clearly visible from the American lines. Kibino clambered out, jumped on a truck, and succeeded in getting his convoy through to the 56th Division. Next day the derelict tankette was credited to the 2nd Battalion, 475th Regiment. But  Encouraged by the additional supplies of gasoline and inspired by the heroic examples of Major Kibino and the personnel of the truck companies, the 56th Division renewed its efforts and, during the next four days effected the evacuation of over 1000 casualties and moved several tons of ammunition to Hsenwi. 

Meanwhile, General Matsuyama began to systematically reposition his forces toward Namhpakka, a strategic maneuver that would enable Chinese troops to occupy Mongyu on January 27. In a broader context, by the end of January, the 36th and 50th Divisions were also engaged in crossing the Shweli River, preparing to advance their offensives further southward. In the Arakan region, Operation Romulus exceeded expectations. The 1st Battalion of the 111th Regiment had been defending Akyab. On December 31, as the rear guard of the Sakura Detachment crossed the Kaladan River and moved eastward the Battalion was ordered to withdraw to Ponnagyun. As intelligence suggested very few Japanese were left on Akyab island, a recce aeroplane reported the locals showing no anxiety and on January 2 messages were dropped in Urdu and Burmese asking them to sit on the ground if the island was still occupied or stand with their hands in the air if not. Captain Jimmy Jarrett of ‘C’ Flight, 656 AOP Squadron, then landed to a rousing reception and found the Japanese had quit on December 31, although nobody believed him until a senior officer flew in to confirm it.

This prompted General Christison to swiftly initiate an amphibious invasion. Notably, this operation was executed without the anticipated naval bombardment and without deploying the reserve 26th Indian Division. As a result, the 3rd Commando Brigade successfully captured Akyab on January 3, facing no resistance, and the 25th Indian Division soon followed, reinforcing the area. From Akyab, the 9th York and Lancasters were transported by boat to establish a strategic blockade along the Yo River at Ponnagyun. There, they encountered significant Japanese forces. After a fierce engagement, however, the Japanese defenders were compelled to retreat toward Myohaung by January 11. In response to the evolving situation, Admiral Mountbatten devised a plan to land the 3rd Commando Brigade and the 25th Division on the Myebon Peninsula. This operation aimed to sever the primary lines of communication for Japanese forces, while preparations were made for the 26th Division to conduct a landing on Ramree Island.

In response to the urgent military situation, Operation Passport was swiftly conceived and executed on January 12. British-Indian forces successfully landed at the southern tip of the peninsula, supported by both air and naval operations. Once ashore, the commandos advanced inland, facing intense resistance from fortified hill positions. Their efforts culminated in the capture of Pagoda Hill and the village of Myebon. However, as they pushed forward, opposition intensified, making it increasingly difficult for the British-Indian troops to reach Hill 831.

Simultaneously, the 82nd West African Division, now commanded by Major-General Hugh Stockwell, entered the Kaladan Valley to relieve the 81st Division, which had been engaged in combat for over a year. The West African forces began to apply pressure against the Matsu Detachment units stationed at Myohaung and Minbya, although these Japanese forces managed to maintain their positions despite the mounting assaults. Meanwhile, planning was underway for the deployment of the 3rd Commando Brigade and the 51st Indian Brigade to land at Kangaw, coinciding with General Lomax’s invasion of Ramree Island. 

Early on January 21 the naval bombardment group opened fire. Christison and the other Force Commanders were watching through field glasses from the bridge of HMS Queen Elizabeth in her first engagement since the Dardanelles in 1915. Christison later said: ‘Some shells fell on a marsh behind the Jap defences, and I saw a number of duck spring up. “Duck”, I shouted. “The Royal Navy never ducks”, said the Admiral.’ With her second salvo Queen Elizabeth scored a direct hit on the Japanese ammunition depot, which facilitated the landing operations. The 71st Indian Brigade successfully captured Kyaukpyu with minimal resistance. This victory enabled them to advance toward Minbyin and Kyaupyauk, both of which fell into their hands by January 23.

In the subsequent days, the brigade continued its advance toward the Yanbauk Chaung, where they encountered fierce Japanese defenses. At the same time, other elements of the division worked to secure Cheduba and Sagu Kyun Islands, further consolidating their strategic position in the region. On January 22, the commandos and the 51st Brigade successfully landed in the Kangaw area near the Min River. However, they faced violent and frequent counterattacks from Japanese forces, which hindered their ability to expand their beachhead. Despite these challenges, the intense pressure from the commandos ultimately forced the Japanese defenders at Hill 831, Myohaung, and Minbya to retreat toward Kani, marking a significant shift in the operational landscape.

General Krueger's forces advanced against Japanese defenses, capturing key positions despite heavy resistance and casualties. Meanwhile, in Burma, British-Indian troops advanced, seizing key locations despite heavy resistance. Both fronts faced intense combat, leading to significant territorial gains against Japanese forces by the end of January.

- 165 - Pacific War Podcast - South China Sea Raid - January 14 - 21 , 1945

Last time we spoke about the invasion of Luzon. As Operation Mike 1 commenced, General Swift’s 1st Corps prepared to assault Lingayen Gulf while General Griswold’s 14th Corps rehearsed at Huon Gulf. Despite successful diversionary strikes, Japanese forces anticipated an invasion. On January 2, enemy ships were spotted heading towards Luzon, confirming fears of a large-scale operation. Kamikaze attacks intensified, damaging Allied vessels, including the USS Long, which sank after being hit. Amidst bombardments, Filipino citizens demonstrated resilience despite the destruction, reflecting their loyalty and hope during the turmoil. As dawn broke on January 9, Kinkaid’s amphibious convoys approached Lingayen Gulf, initiating a fierce assault. Preceded by heavy bombardments, American forces landed on the beaches, facing minimal resistance. The 14th Corps advanced toward key locations, while the 1st Corps secured strategic positions despite enduring sniper fire. By nightfall, they established a significant beachhead. Despite sporadic Japanese counterattacks, American troops pressed forward, and reinforcements were deployed to maintain momentum. The stage was set for a crucial campaign in Luzon.

This episode is the South China Sea Raid

As we last left off, the 1st and 14th Corps had just successfully established a beachhead on Lingayen Gulf. On January 11, General Krueger further reinforced his position by landing additional reserves, aiming to effectively confront the formidable enemy forces entrenched in the eastern hills. Concurrently, Admiral Halsey’s 3rd Fleet units made their entrance into the South China Sea to execute an ambitious raid known as Operation Gratitude. This operation was prompted by misleading intelligence reports suggesting that the hybrid battleship-carriers Ise and Hyuga were stationed in Cam Ranh Bay. In response, Halsey ordered Admiral Bogan’s Task Group 38.2 to launch an assault on these supposed targets. This task group was primarily composed of the battleships New Jersey and Wisconsin, which were directed to bombard the bay and eliminate any Japanese vessels that had sustained damage from prior airstrikes.

To enhance their operational capabilities, Halsey established Task Group 38.5, specifically designed for night operations, which included the night-capable carriers Enterprise and Independence. On January 12, aircraft from these carriers were deployed for a predawn reconnaissance mission over Cam Ranh Bay and its adjacent waters in search of enemy targets. Despite their efforts, the search yielded no results, indicating that the earlier intelligence had been inaccurate. Nevertheless, all three carrier groups proceeded with their planned strikes at 07:30, while the surface action group advanced toward Cam Ranh.

Halsey’s strategic gamble proved to be remarkably successful. Although the Ise and Hyuga were not present in the bay, American aviators discovered a wealth of enemy shipping, including three significant Japanese convoys. Sherman’s TG 38.3 encountered the most valuable target off Qui Nhon north of Cam Ranh. This was convoy Hi-86 with nine merchants and a heavy escort. The convoy had departed Cape St Jacques on January 9 and was headed north. The escort comprised light cruiser Kashii and five kaibokan. Late on January 11, it reached Qui Nhon Bay and anchored. After leaving Qui Nhon Bay, it was discovered by TG 38.3. In two large attacks, aircraft from Essex, Ticonderoga, Langley, and San Jacinto laid waste to the convoy. None of the nine merchant ships in the convoy survived this onslaught. Cargo ships Yoshu Maru and Eiman Maru (loaded with bauxite and raw rubber), along with tanker San Luis Maru, were sunk. The other six ships were damaged and forced to beach. Otsusan Maru (a cargo ship converted to tanker), passenger-cargo ship Tatebe Maru, cargo ship Kyokuun Maru, cargo ship Yusei Maru, ore carrier Tatsubato Maru, and cargo ship Banshu Maru No. 63 all became constructive total losses. The escort for this large convoy met a similar fate. Light cruiser Kashii was hit amidships by a torpedo in the early afternoon. This was followed by two bomb hits aft that detonated her depth-charge magazine. Kashii sank stern first with 621 members of her crew; only 19 survived. CD-23 was attacked north of Qui Nhon and sunk with her entire crew of 155 officers and men. CD-51 suffered the same fate. After she blew up and sank, her depth charges detonated with fatal consequences for any survivors; 159 men were lost. From the entire convoy, only kaibokans Daito and Ukuru, and corvette CD-27 survived, albeit in a damaged state.

As a result, Admiral McCain’s Task Force 38 conducted an impressive total of 984 strike missions throughout the day. This relentless assault led to the sinking of the light cruiser Kashii, two minesweepers, eight kaibokans, two subchasers, five transport ships, fourteen cargo vessels, and nine oilers. Additionally, four kaibokans, one subchaser, three transports, four cargo ships, and two oilers were damaged. This operation marked the highest number of ships sunk by airstrikes in a single day during the war, showcasing the effectiveness of the American air campaign and the critical role of intelligence in naval warfare.

In addition to inflicting significant damage on Japanese shipping, the aviators under Admiral Halsey achieved remarkable success by claiming the destruction of 113 enemy aircraft, both in the air and on the ground, while sustaining the loss of 23 American aircraft. The impact of these operations extended beyond aerial engagements; critical infrastructure was also targeted. Airfields, docks, and oil storage facilities located between Tourane and Saigon suffered considerable damage. Notably, the railway station in Nha Trang and a vital bridge on the route connecting Saigon to Bien Hoa were also affected, disrupting transportation and supply lines.

 

Meanwhile, Bogan’s surface strike group was unable to locate any Japanese vessels during their operations and instead focused their firepower on bombarding Cam Ranh Bay, further demonstrating the ongoing conflict's intensity.

Turning to the situation in Luzon, the 1st and 14th Corps were poised to advance their offensives. To the west, the 185th Regiment and the 40th Reconnaissance Troop initiated a push toward the recently vacated Port Sual. The 160th Regiment maintained a watchful presence at Aguilar, while patrols from the 148th Regiment ventured into towns occupied by guerrilla forces, specifically Urbiztondo and Bayambang. In the eastern sector, the 6th Division was temporarily held back to prevent the creation of a potentially hazardous gap along the front of the 1st Corps. However, the reinforced 43rd Division continued its advance against the most formidable Japanese defenses encountered on Luzon to date. Along the coastline, the 158th Regiment dispatched patrols into Damortis, discovering the town largely deserted. The 172nd Regiment attempted an attack on Hill 580, which ultimately proved unsuccessful, while the 63rd Regiment was deployed to close the widening gap between the 158th and 172nd Regiments.

The primary objective of these coordinated efforts was to defeat Major-General Sato Bunzo’s 58th Independent Mixed Brigade and secure control of the Damortis-Rosario road. The Damortis-Rosario road, a 2-lane, concrete-paved section of Route 3, led east from the junction of Route 3 and the coast road at Damortis, about 8 miles north of San Fabian, to the junction of Routes 3 and 11, 8 miles inland and a mile east of Rosario. Seizure of the Damortis-Rosario stretch of Route 3 would present 1st Corps with an easy means of access to Route 11, in turn providing a 2-lane asphalt-paved axis of advance toward Baguio along the deep valley of the Bued River. Equally important, if the 1st Corps could quickly gain control over the Damortis-Rosario road and the Routes 3-11 junction, the corps could largely overcome the threat of counterattack against the 6th Army's beachhead from the north and northeast. The Damortis-Rosario road ran sometimes across wooded ravines and sometimes over ridge tops for 3/4 of the way to Rosario, and then continued across open farm land and through Rosario to a junction with Route 11. The road was dominated by broken ridges and steep-sided hills to both the north and the south for the first 5 miles inland. South of the road the hills and ridges were grass-covered; to the north many of the draws and ravines contained thick scrub growth. Bare, steep heights north, northeast, and east of Rosario controlled the Routes 3-11 junction. The 58th Independent Mixed Brigade, defending the Damortis-Rosario road, had all the advantages of observation, while the relatively soft rock and dirt mixture of the hills and ridges gave the brigade ample opportunity to indulge in what was soon to appear to the 1st Corps as the Japanese Army's favorite occupation--digging caves and tunnels. Achieving this would mitigate the threat of a counterattack against the 6th Army's beachhead from the north and northeast. With the security of its left flank assured, the 14th Corps could then accelerate its advance toward General Krueger’s main objective: the Central Plains-Manila Bay region. This strategic maneuvering was crucial for consolidating American forces and ensuring a successful campaign in the Philippines.

At the same time, the 169th Regiment faced ongoing challenges at Hill 318 and the southern part of the Japanese-held third ridgeline, while the 103rd Regiment made unsuccessful attempts to advance toward the Hill 200 complex, which was firmly defended by the 2nd Battalion, 64th Regiment. Meanwhile, General Tominaga executed his final large-scale kamikaze attack during the Philippines Campaign, successfully damaging two destroyer escorts, one destroyer transport, and five merchant ships. The final attacks were recorded on January 13. Only two suicide aircraft were dispatched, both IJA Ki-84 Franks. One surprised the crew of escort carrier Salamaua. Unengaged by antiaircraft fire, the Frank hit amidships. One of the aircraft’s bombs exploded on the hangar deck and the second passed through the ship creating a hole near the waterline. The carrier was left without power while major fires took hold. Damage control was ultimately successful, but not before 15 were killed and 88 wounded. Salamaua was out of the war until April. Also on this day, attack transport Zeilin was hit by a probable IJN aircraft conducting an impromptu suicide attack.

Ultimately, the 4th Air Army was scheduled to evacuate to Formosa on January 15, marking the end of the threat from Japanese air power in the Philippines, although the Allies were not yet aware of this. Since the initial kamikaze assault on the Mindoro-bound convoys on December 13, Japanese aircraft had sunk 24 vessels and damaged 67 others. Casualties from these air attacks aboard ships were approximately 1,230 men killed and 1,800 wounded, while the Allies estimated they had destroyed around 600 Japanese aircraft during the same timeframe. Back in Lingayen Gulf on January 13, the 172nd Regiment once again advanced up the grassy, steep slopes of Hill 580, successfully securing most of the area against fierce resistance. Simultaneously, the 63rd Regiment attacked north from Hill 247 and captured Hill 363, despite lacking artillery support.

Artillery support was to have been provided by the 43rd Division's 155-mm. howitzer battalion, the 192nd Field Artillery Battalion, since the 63rd Regiment's own 105-mm. battalion had been sent south with the rest of the 6th Division. Unfortunately, the 192nd Field Artillery did not learn it was to support the 63rd until after dark on January 12, and could not start moving to good close support positions until daylight on the 13th, after the 63rd had started its attack. Unlike a 105-mm. battalion, the 192nd did not normally operate in direct support roles and lacked the forward observers and communications the lighter battalions possessed. The 192nd might therefore have been expected to take some time to prepare for its direct support mission, but the battalion reported it could have provided some support--with at least one battery--by noon on the 13th had not Colonel Ralph C. Holliday, commanding the 63rd Regiment, insisted that wire be laid for artillery liaison officers and forward observers, a job that was not completed for almost 36 hours. Colonel Holliday may have been influenced in his decision by the fact that the artillery's SCR-610 radio did not work efficiently in the broken terrain of the middle ridge line where the 63rd was attacking. It was not, indeed, until the 43rd Division had supplied the 192nd Field Artillery with infantry SCR-300 sets that the battalion was able to establish satisfactory radio communications. Then, on January 14, the first radio brought up to the battalion's forward observers was promptly destroyed by Japanese artillery, which also cut wire that had already been laid. Support was again delayed, so the entire battalion was not in position and ready to give the 63rd Regiment the support it needed until midafternoon on January 15. Meanwhile the 169th Regiment completed the clearing of the southern end of the ridgeline, while the 103rd Regiment continued its unsuccessful efforts to take Hill 200.

To the west, the 6th Division established a fortified line extending from Malasiqui to Manaoag. They promptly dispatched reconnaissance units to the east and south to gather intelligence on enemy movements. The 185th Regiment achieved a significant victory by successfully assaulting Port Sual, while the 160th Regiment engaged in several skirmishes with the reinforced 23rd Reconnaissance Regiment, which had retreated from Port Sual at the onset of the conflict. Meanwhile, patrols from the 148th Regiment advanced into Wawa, strategically located between Bayambang and Urbiztondo. The following day, the 185th Regiment continued its momentum by capturing the crucial road junction town of Alaminos on the Bolinao Peninsula. Some of its elements also pushed northward toward Cabalitan Bay, where they discovered that Allied Naval Forces had already landed to establish a seaplane base, enhancing their operational capabilities in the region.

Looking to the east, the 103rd Regiment made gradual but consistent progress along Hill 200, while the 169th Regiment executed a costly frontal assault to clear Hill 318, suffering significant casualties in the process. The 172nd Regiment advanced north along the third ridge, successfully seizing Hill 565 despite facing scattered resistance. The 63rd Regiment continued its slow advance northward, persistently harassed by Japanese artillery and mortar fire, which impeded their progress. Additionally, the 158th Regiment initiated an offensive toward Rosario but was quickly compelled to retreat due to intense Japanese artillery and machine-gun fire. In contrast, General Yamashita, while cautious about launching a major counteroffensive, recognized the necessity of limited offensive actions to regain the initiative. He believed that such actions would effectively disrupt the enemy's advance inland. Consequently, he ordered General Nishiyama’s 23rd Division to conduct a robust raiding attack against the San Fabian-Alacan sector during the night of January 16. This strategic decision aimed to exploit the element of surprise and inflict damage on the enemy forces, thereby buying time for his troops to regroup and fortify their positions.

In a strategic initiative aimed at maximizing the destruction of enemy weaponry, supplies, and critical base installations, the 58th Brigade, along with the 71st and 72nd Regiments, was instructed to assemble specialized "suicide" raiding units. These units comprised carefully selected soldiers, heavily armed with automatic firearms and supported by demolition teams trained for explosive operations. In addition, a fourth unit was to be formed from the Shigemi Detachment of the 2nd Armored Division, which had recently positioned itself on the southern flank of the 23rd Division. This unit would consist of a mobile infantry company and a medium tank company. The operational plan called for these units to breach the enemy’s beachhead perimeter simultaneously at various locations on January 17. Their objective was to swiftly execute their missions and then withdraw to safety. As preparations for this limited counteroffensive unfolded, the American forces continued their own offensive operations, which had commenced on January 15.

In this context, the 158th Regiment launched an eastward assault, successfully advancing approximately 1,000 yards. Meanwhile, the 63rd Regiment cautiously pushed forward over a mile and a half northward from Hill 363. The 172nd Regiment made a rapid advance to the Cataguintingan road junction, effectively establishing a battalion at the edge of Route 3, about a mile and a half west of Rosario. In contrast, the 169th Regiment encountered challenges during a two-pronged attack on Hill 355, leading General Wing to order the regiment to bypass the hill to the south and reposition overland to Route 3 at barrio Palacpalac. Conversely, the 103rd Regiment achieved significant success in their assault on the Hill 200 complex. Further to the west, patrols from the 185th Regiment advanced westward, successfully reaching Dasol Bay. Additionally, a battalion from the 129th Regiment crossed the Agno River at Wawa and continued south along a dusty gravel road toward Camiling. Other elements of the 160th Regiment also moved down from Aguilar to Camiling, consolidating their position in the area.

After completing refueling operations over the previous days, Task Force 38 resumed its northern advance to launch an assault on Formosa on January 15. Despite Admiral McCain's recommendation to cancel the strike due to inclement weather conditions, Admiral Halsey opted to proceed with the operation. As a result, a series of airstrikes were executed against Formosa and the Pescadores Islands throughout the day. The 16 fighter sweeps conducted during this operation managed to destroy only 16 Japanese aircraft in the air and an additional 18 on the ground. However, the bombing missions targeting enemy shipping proved more effective, leading to the sinking of the destroyers Hatakaze and Tsuga, along with one transport vessel and two merchant ships, albeit at the cost of losing 12 American aircraft.

Following these strikes, Task Force 38 redirected its course toward Hong Kong, which came under attack on January 16. Unfortunately, the American forces encountered severe weather conditions and faced intense anti-aircraft fire. This resulted in a limited success, with the Americans sinking just one transport ship, five oilers, one cargo vessel, and one guardboat. Additionally, they inflicted damage on the destroyer Hasu, three destroyer escorts, one corvette, one transport, and one oiler. The strikes also caused significant destruction to key infrastructure, including Kai Tak Airport, the Kowloon and Taikoo docks, the Aberdeen dockyard, the Kowloon-Canton railway, and the Macau Naval Aviation Center. In a broader campaign, the Americans executed secondary strikes against Canton and Hainan Island, as well as targeting several airfields along the Chinese coast, particularly between the Leizhou Peninsula and Swatow. However, this ambitious operation came at a steep cost, with Task Force 38 suffering a total loss of 49 aircraft—27 due to operational issues and 22 as a result of enemy action. With the South China Sea Raid concluded, Admiral Halsey directed his fleet toward the Luzon Strait, adhering to Admiral Nimitz's request. Ultimately, Halsey's aggressive campaign resulted in the destruction of approximately 300,000 tons of Japanese shipping and an estimated 615 Japanese aircraft, all at the expense of 201 American planes.

Returning to the Lingayen Gulf, Wing's offensive operations persisted on January 16. The 63rd, 158th, and 172nd Regiments continued their assaults toward the town of Rosario. However, they encountered fierce resistance from the determined Japanese defenders, which significantly hampered their progress. In contrast, the 169th Regiment achieved a notable advancement by reaching Palacpalac, while the 103rd Regiment successfully captured the strategically important Hill 200 complex. From their newly secured positions, elements of the 103rd Regiment pursued the retreating Japanese forces toward Pozorrubio. Meanwhile, two reinforced companies advanced toward Potpot, and both towns ultimately fell into American hands on January 17.

In a broader strategic context, General Krueger directed General Griswold to dispatch additional troops south of the Agno River in preparation for a decisive push toward Manila. By January 17, the 14th Corps had established outposts at key locations including Moncada, Nampicuan, Anao, and Paniqui, solidifying their control over the area. Simultaneously, Japanese General Nishiyama was preparing to initiate a local counteroffensive by nightfall on January 16. However, the 72nd Regiment's raiding unit was unable to participate due to enemy penetrations disrupting their plans. On the northern front, Sato’s raiding unit conducted a minor raid against an artillery position held by the 158th Regiment, but this attack proved largely inconsequential. In contrast, the raiding unit from the 71st Regiment executed a more impactful maneuver by advancing down the Bued River valley. They successfully infiltrated the rear installations of the 172nd Regiment, where they ignited a gasoline dump, damaging several trucks in the process. This raid resulted in the deaths of two American soldiers and injuries to eight others. At Palacpalac, confusion reigned as the retreating 2nd Battalion of the 64th Regiment inadvertently engaged with the perimeter of the 1st Battalion of the 169th Regiment. This chaotic encounter cost the Japanese approximately 100 men before they retreated in disarray, further illustrating the tumultuous nature of the battlefield.

In a dramatic turn of events, the tank raiding unit launched a surprise attack on the newly established outpost at Potpot. Initially, the first two tanks managed to breach the perimeter, unleashing a barrage of machine-gun fire in all directions as they sped away down the road toward Manaoag. However, the remaining tanks, along with their infantry support, encountered fierce resistance from determined defenders, leading to a sharp and intense fire fight that lasted two hours. Despite their initial success, the attackers were ultimately repelled. As dawn broke, the two tanks that had previously penetrated the defenses returned down the Manaoag road, but this time they met their demise, successfully destroyed by the defenders who had regrouped and fortified their positions. Since the onset of the invasion, the 1st Corps had suffered significant casualties, with approximately 220 men killed and 660 wounded. In stark contrast, Griswold’s forces experienced far lighter losses, with only 30 killed and 90 wounded. With the enemy's counterattack thwarted, the 43rd Division managed to secure positions that effectively reduced the likelihood of another large-scale surprise offensive from the Japanese forces. However, to completely eliminate the remaining threats, Commander Wing recognized the necessity of securing control over the Rosario junction and establishing a solid hold on Route 3 to the south of this critical point.

The challenge was considerable, as Japanese artillery, mortars, and machine guns positioned on the surrounding high ground commanded all approaches to Rosario. Consequently, Wing had no choice but to restrict the 172nd Regiment to a defensive holding action on its left flank while directing its right flank to seize the high ground immediately to the north and northwest of Rosario. In addition, the 63rd and 158th Regiments were tasked with neutralizing the enemy stronghold along the Rosario-Damortis road. To expedite the capture of the road junction, Wing also planned for the 103rd and 169th Regiments to launch an offensive drive north along Route 3. This coordinated effort aimed to strengthen their strategic position and diminish the Japanese threat in the region, ultimately paving the way for a more secure and stable front.

In response to the evolving battlefield situation, General Krueger ultimately ordered General Mullins’ 25th Division to secure the right flank previously held by Wing’s forces. This strategic move prompted the 27th and 161st Regiments to begin the process of relieving the 103rd and 169th Regiments. By doing so, the 6th Division would be able to resume its advance, now directed towards Urdaneta and the Cabaruan Hills, critical areas for the ongoing campaign. To the west, Krueger aimed to maintain the 14th Corps along the Agno River line until General Swift's 1st Corps could effectively neutralize the enemy resistance stretching from Damortis to Urdaneta. This would enable Swift's forces to maneuver southward alongside Griswold's corps. However, General MacArthur was eager to initiate a southern advance toward Manila as soon as possible. Consequently, he instructed the 14th Corps to reposition its main forces back to their previous outpost line south of the Agno by January 20. Following this, the corps was to launch an offensive towards Tarlac and Victoria. Once they established a presence along the Tarlac-Victoria line, the corps would prepare to advance toward Clark Field, a vital objective necessary for the successful neutralization of Japanese strongholds at Iwo Jima and Okinawa.

To bolster this offensive, MacArthur also planned to deploy the 11th Corps on the western coast of Luzon, just north of the Bataan Peninsula. This amphibious operation aimed to disrupt Japanese defensive strategies in the Clark Field area, thereby enhancing the overall effectiveness of the Allied campaign. In contrast, in reaction to the loss of the Hill 200 complex, Japanese General Yamashita ordered the 2nd Tank Division to advance immediately into the Tayug sector. There, Lieutenant-General Iwanaka Yoshiharu would take command of the 10th Division forces already stationed in the region. The armored units were tasked with positioning themselves along the trail north of San Nicolas and on both sides of the Ambayabang River, with the objective of containing any potential enemy advances to the east. Additionally, the Shigemi Detachment received orders to move its main forces from San Manuel to Binalonan, where they were to defend the town resolutely, prepared to hold their ground against any assault.

In addition, General Okamoto was tasked with positioning his main forces to secure the immediate approaches to San Jose. Meanwhile, General Tsuda's 105th Division was instructed to advance northward through Cabanatuan as quickly as possible to establish defensive positions behind the 10th Division, specifically at Minuli and north of Carranglan. However, not all of these strategic plans could be effectively executed. By January 17, Yamashita discovered that the Villa Verde Trail was impassable for tanks and trucks, rendering it unusable for the planned armored movements. Furthermore, the terrain in the Tayug-San Nicolas area proved to be unsuitable for armored operations, complicating the situation further.

On January 17 the 14th Area Army commander belatedly learned that the 10th Division had never concentrated at San Jose and that it had made no real effort to dispose itself along the entire Tayug-Umingan-Lupao-San Jose defense line for which it was responsible. General Okamoto, the division commander, had decided that he did not have sufficient strength to hold the relatively open ground assigned to him. Most of his 39th Regiment was with the Kembu Group; the bulk of the 10th Regiment, greatly understrength, was attached to the 103rd Division for the defense of northern Luzon; and, at least as late as of January 15, he had received no word as to when he might expect the attached Tsuda Detachment to arrive in the San Jose area from the east coast. He had therefore withdrawn most of his troops up Route 5 from San Jose and had started disposing them along the line Yamashita had intended the 105th Division to hold; leaving behind only a reinforced infantry company and two artillery battalions to secure the all-important railhead. Okamoto had directed the 10th Reconnaissance Regiment to remain in the San Nicolas area, and he stationed three or four rifle companies of his 63rd Regiment along the Tayug-Lupao line and in rising ground to the southwest.

Confronted with these unexpected developments, Yamashita concluded that he had no choice but to accept the redeployment of the 10th Division as an established fact. Consequently, he ordered the 2nd Tank Division, which had already begun its movement toward Tayug, to concentrate its main forces southeast of Tayug to safeguard the immediate approaches to San Jose. Additionally, the 6th Tank Regiment was assigned to position itself in Muñoz to cover the southwestern approach to the area. To further bolster defenses, Tsuda was instructed to deploy two of his five advance battalions to San Jose. However, as these tactical adjustments were being made, it became necessary to shift focus away from Luzon and turn attention toward Leyte, where the final operations on the island were unfolding. It is important to note that the majority of General Suzuki’s forces had successfully retreated to the Villaba-Mount Canguipot region, although some strong elements remained isolated further to the east. With General Eichelberger’s 8th Army assuming control of the island, American forces commenced the final phase of operations to secure Leyte, methodically working to eliminate any remaining pockets of resistance.

From January 1 to February 15, the 11th Airborne Division conducted patrols in the Burauen area, where they engaged and successfully eliminated a well-entrenched enemy force positioned on the southern slopes of Mount Majunag. Meanwhile, the 96th Division carried out extensive patrols in the eastern mountainous regions before taking over from the 11th Airborne Division. In the southern part of the island, the 7th Division launched numerous patrols and deployed a reinforced battalion that effectively neutralized all enemy forces in the Camotes Islands. Additionally, the 77th Division focused on clearing various pockets of enemy resistance located in northwestern Leyte.

By late January, the Americal Division arrived to assist in the cleanup operations in Samar and Leyte, a mission that was successfully completed by February 24, with support from the 1st Filipino Regiment. However, during this time, Japanese General Suzuki was formulating his strategy for Operation Chi-Go. This operation involved the amphibious movement of several military units to different islands within the Visayas using large motorized landing barges. Suzuki's initial plan entailed deploying the majority of the 1st Division to establish a garrison on Cebu Island, while the headquarters of the 35th Army was to relocate to Davao. This strategic move would enable him to take direct command of military operations on Mindanao. Following this, he intended to dispatch the 41st and 77th Regiments to Mindanao, assign the 26th Division to the Bacolod area on Negros Island, and send the 5th Regiment along with units from the 102nd Division to Cebu. Furthermore, the 16th Division and the 68th Brigade, commanded by General Makino, were to remain in Leyte to engage in guerrilla warfare tactics. 

The 102nd Division presented certain difficulties. There had been instances of 40 to 50 deserters fleeing to Cebu or Negros on boats they had built for themselves. Deserters that were apprehended were court-martialed. General Suzuki for some time had been out of touch with General Fukei, the commanding general of the 102nd Division, which was in the Mt. Pina area. By chance, one of Suzuki's officers learned that Fukei was planning to evacuate to Cebu. Suzuki was incensed since he and his staff felt that Fukei "was violating the military code in taking these steps without consent." He therefore ordered Fukei to remain at Leyte. Fukei did not answer but his chief of staff sent the following reply: "We appreciate the efforts of Army but at the present time we are very busy preparing for retreat. The division commander and chief of staff are unable to report to Army Headquarters." Suzuki was "entirely displeased" with the reaction of Fukei and sent his chief of staff, General Tomochika, to investigate the situation. When Tomochika arrived he found that Fukei, with his chief of staff and some headquarters personnel, had already left for Cebu. The sequel to these events was that Suzuki relieved Fukei of his command and ordered him to remain on Cebu until he received further orders. Upon the arrival of Suzuki in Cebu in the spring of 1945, Fukei was sentenced to confinement for thirty days. Suzuki asked IGHQ in Tokyo for authority to court-martial Fukei but no reply was forthcoming. In the end, Fukei was released and later returned to command of the 102nd Division.

In the midst of ongoing military operations, Suzuki implemented measures to ensure that the forces stationed on Leyte could sustain themselves. He instructed his troops to make the most of local resources by utilizing available food and materials. This included directives to cultivate sweet potatoes and Indian corn, with the hope of sourcing all necessary provisions from the surrounding areas outside their operational base. However, the Japanese forces faced significant challenges due to relentless American air raids and mop-up operations, which severely hindered their ability to procure supplies. The hostile environment made it difficult for them to plant and harvest the crops they had intended to grow. Despite these obstacles, the Japanese managed to capitalize on the conclusion of the harvest season. They were able to secure substantial amounts of food that had been stored by local Filipinos, including a considerable quantity of coconuts and sweet potatoes. By early January, the 1st Division began its gradual movement toward Cebu, successfully transporting around 800 men to the island by mid-January. Unfortunately, the situation worsened as enemy PT boats established a stringent sea blockade, rendering maritime transportation impractical until mid-March. This blockade left approximately 2,000 men from the 1st Division, along with other units of the 35th Army, stranded on Leyte.

Simultaneously, the Imahori Detachment, alongside the Mitsui Shipping Unit and the 77th Regiment, advanced to the southern Matag-ob area and subsequently moved toward Villaba, reaching their destination in early February. The majority of the 26th Division also made progress, arriving in the region north of Ormoc in mid-January before commencing a northwestward movement. By February, they successfully established contact with the rest of the 35th Army. Meanwhile, the remnants of the 16th Division could only reach the Valencia area in February, where they would remain until the end of the month. For the foreseeable future, the Japanese units left behind on Leyte faced the daunting task of defending against the advancing Americal Division and the 1st Filipino Regiment, which were steadily gaining ground.

Admiral Halsey launched Operation Gratitude, targeting Japanese shipping. Despite misleading intel, they decimated enemy convoys, showcasing the effectiveness of airstrikes and securing strategic advances in Luzon. American forces advanced through Luzon while Task Force 38 struck Formosa and Hong Kong. Despite fierce Japanese resistance and challenging weather, the Allies steadily gained ground, though both sides suffered significant losses in the campaign.

- 164 - Pacific War Podcast - Invasion of Luzon - January 7 - 14 , 1945

Last time we spoke about the Aitape-Wewak Campaign. General Dunckel’s task force successfully invaded Mindoro, establishing airfields to support operations on Luzon. With General Eichelberger's 8th Army and General Krueger's 6th Army poised to capture Lingayen Gulf, guerrilla forces on Luzon provided crucial intelligence. As plans for the Luzon invasion solidified, General Yamashita prepared defenses, predicting an assault between January 10 and 20. Despite dwindling resources, he aimed to delay the enemy’s advance. Meanwhile, Allied forces readied for a swift amphibious attack to secure Manila and restore the Philippine government. In December, Australian forces established outposts at Yasile and Yambes, successfully repelling Japanese attacks. After fierce clashes, they advanced 40 miles along the coast. Meanwhile, the U.S. military bolstered defenses in Saipan and launched bombing raids on Japanese facilities, achieving mixed results. Despite heavy losses, they began to impact Japanese production capabilities. As the month ended, the Japanese launched a final assault on the Marianas, but the Allies continued their strategic advances, setting the stage for future operations.

We last left off with the plans for Operation Mike 1 being finished. General Swift’s 1st Corps was ready to land on the eastern beaches of Lingayen Gulf, while General Griswold’s 14th Corps prepared to go ashore on the western beaches. Additionally, successful diversionary operations had been conducted on Mindoro, and Admiral McCain’s Task Force 38 executed several moderately successful strikes against Formosa and the Ryukyu Islands in early January. Meanwhile, the 14th Corps elements staging at New Britain completed loading on 10 December; those mounting at Bougainville finished two days later. On the 17th all groups of the III Amphibious Force rendezvoused at Huon Gulf, eastern New Guinea, to rehearse the Lingayen assault. General Griswold felt that the 37th Division's rehearsal was satisfactory but had much fault to find with the 40th Division, remarking upon a "general failure to observe the spirit of the rehearsal." As a result, further training was conducted at Manus Island in the Admiralties, where the convoy reassembled on 22 December.

On December 27, Admiral Wilkinson dispatched his LSTs and LSMs, followed by the remainder of Task Force 79 four days later. On the same day, Admiral Barbey’s convoy, which included Major-General Leonard Wing’s 43rd Division, loaded at Aitape before proceeding to Sansapor to load Major-General Edwin Patrick’s 6th Division. Task Force 78 departed Sansapor on December 30, heading to a rendezvous point with other elements of Admiral Kinkaid’s Luzon Attack Force. By January 4, all components of Task Force 77 had successfully gathered at Leyte Gulf, with MacArthur personally boarding the light cruiser Boise. Kinkaid’s minesweepers, Admiral Oldendorf’s Bombardment and Fire Support Group, and most of Admiral Durgin’s escort carriers had already left the gulf on January 2 to conduct preliminary operations off Luzon. By January 6, the rest of the Luzon Attack Force began moving toward Lingayen Gulf, led by Admiral Berkey’s light cruisers.

As Mindoro-based aircraft significantly increased the intensity of their assaults during the last week of December—sinking seven transports and two escorts, and destroying over 140 aircraft. General Yamashita's tense and expectant forces were still racing against time to complete,their battle preparations when the first warnings came that the enemy was again on the move. At 1322 on 2 January, a naval lookout post on Surigao Strait reported that a long train of about 80 enemy ships, screened by destroyers, was moving through the strait into the Mindanao Sea. Other reports which followed immediately warned that large numbers of invasion craft were gathered in the Leyte, Palau and Marianas areas, and that enemy submarines had appeared in force off the west coast of Luzon. At first it was thought that the enemy convoy was merely a reinforcement and resupply group destined for Mindoro. On 3 January, however, developments began to point more conclusively toward a full-scale amphibious operation against Luzon. In the afternoon, just as the initially sighted enemy group passed into the Sulu Sea, a large enemy naval task force, including 12 escort carriers, four battleships and eight cruisers, was reported following in its wake through Surigao Strait. Another delayed report stated that an enemy transport convoy of 90 ships, under strong naval escort, had been spotted the previous day northwest of Palau, heading in the direction of Leyte Gulf.

General Yamashita grew concerned that a large-scale amphibious operation against Luzon was imminent. Consequently, he decided to relocate his headquarters to Baguio. These concerns were validated in early January when Japanese lookouts spotted Kinkaid’s warships and transports approaching the island. In response, General Tominaga ordered aggressive kamikaze attacks on the Allied vessels, with a major assault on January 4 causing severe damage to the escort carrier Ommaney Bay, which ultimately had to be scuttled. The following day, Japanese attacks persisted, damaging two escort carriers, two cruisers, and three destroyers, among other ships. In retaliation, Durgin’s carrier aircraft launched strikes on Manila Bay, successfully sinking the destroyer Momi and damaging the Hinoki. On January 6, McCain’s carriers joined the effort, with American pilots tasked with targeting air facilities at Manila and Clark Field. Despite adverse weather conditions limiting the effectiveness of the strike, they succeeded in sinking one transport and six oilers, as well as destroying 32 Japanese aircraft. Meanwhile, as Oldendorf’s warships commenced their bombardment and minesweeping operations, kamikaze attacks continued.

The destroyer minesweeper USS Long (DD-209/DMS-12) missed the attack on Pearl Harbor by about two days, but then immediately started anti-submarine patrols and escort missions. Its long trajectory in the Pacific War saw it make escort runs to Midway, Palmyra and Canton; participate in the invasions of Amchitka, Attu and Kiska in Alaskan waters; escort reinforcements to Roi and Namur in the Marshalls; participate in the invasions of the Admiralties, Hollandia, Saipan and Palau; and be one of the first vessels to enter into Leyte Gulf back in October. During the invasion of Lingayen Gulf, Long began mine sweeps on January 6, evading and firing upon Japanese aircraft as she carried out her intricate mission. Shortly after noon, beginning her second run, Long spotted two Zeros heading for her. Long went to 25 knots and opened fire, but a kamikaze crashed into her portside below the bridge about 1 foot above the waterline. With fires and explosions amidships, Long lost power and internal communications, and was unable to fight fires forward. Her commanding officer, Lieutenant Stanley Caplan, fearing an explosion in the forward magazine, gave permission for men trapped on the forecastle to leave the ship; but through a misunderstanding the crew abandoned ship. Later that afternoon a second plane attacked Long and exploded at the same spot, destroying the bridge and breaking the ship's back. Long finally capsized and sank the following morning. Alongside the Long, battleships California and New Mexico, along with the cruisers Columbia, Australia, and Louisville, five destroyers, another minesweeper, and one transport were damaged.

Admiral Oldendorf was worried with good reason. Previously, kamikaze operations against his ships and those of other naval commands, though dangerous, had generally been executed by relatively untrained pilots who had taken few precautions to avoid detection and anti-aircraft fire and who often appeared to be flying partially damaged, lightly armored planes carrying little ordnance. In January the kamikazes had been operating in a far different manner. There was now a definite program of kamikaze operations, for the vast majority of the perhaps 100 Japanese aircraft that had attacked the forces under Admiral Oldendorf's command since January 2 had at least attempted kamikaze crashes. In addition, the pilots seemed to be more skilled. They took every advantage of radar-blanketing terrain, especially in the Lingayen Gulf area, and flew toward target ships at extremely low altitudes, thus helping to avoid both radar and visual detection. Flight tactics included radical maneuvering designed not only to avoid anti-aircraft fire and Allied planes but also to confuse observers as to which ship was the actual target. Finally, many of the kamikaze planes were heavily armored and armed. The Allies had expected great results from the relatively new proximity fuze for shipboard 5-inch antiaircraft weapons, but the Japanese planes usually appeared so suddenly and took such violent evasive action that 5-inch batteries could seldom track properly. The employment of the expensive special ammunition was, therefore, generally useless, and was sometimes even dangerous to friendly ships. Having missed approaching kamikazes by such distances that fuzes were not activated, shells sometimes sailed on to explode on or near Allied vessels, thereby causing some damage and many casualties. 

Concerned about the effectiveness of the kamikaze attacks and recognizing that achieving air superiority did not prevent the enemy's suicide planes, Oldendorf opted for a psychological strategy. He ordered the minesweeper and bombardment groups to persist with their operations, even while sustaining damage, to convince the Japanese that their suicide missions were failing. Kinkaid shared these concerns and requested the cessation of all diversionary air operations to concentrate the main air offensive on Luzon. As a result, Admiral Halsey’s carrier-based aircraft and General Kenney’s ground forces were tasked with neutralizing all Japanese airfields in Luzon, supported by Durgin’s escort carriers. On January 7, McCain’s strikes on Luzon and Oldendorf’s bombardment of the Lingayen beaches continued, while underwater demolition teams entered the gulf to undertake the dangerous mission of dismantling beach obstacles. Again contrary to expectations, no beach obstacles were found. The "frog men" encountered only a little rifle and machine gun fire, and the few beach defenses they observed appeared to be unoccupied. Their tasks and those of hydrographic ships were completed on the 8th.

In retaliation, 20 to 25 kamikazes targeted various segments of the Luzon Attack Force, managing to sink two minesweepers and damage one LST. That night, Kinkaid’s destroyers successfully sank the Hinoki off Manila Bay. However, on January 8, the 3rd Fleet units began advancing towards Formosa, as MacArthur and Admiral Nimitz suspected that the kamikazes were launching from there. Without Halsey’s additional air support, the Japanese suicide planes once again attacked the Luzon Attack Force, this time damaging the cruiser Australia and the escort carriers Kitkun Bay and Kardashan Bay, as well as inflicting damage on an LSI, an LST, and an APA.

Due to significant losses, by the end of the day, the 2nd Air Fleet and the 1st Combined Base Air Force headquarters were disbanded. The 1st Air Fleet received orders to withdraw to Formosa for reorganization, while the severely weakened units of the 4th Air Army were set to continue limited attack operations for a short time until a final evacuation could be carried out. Returning on the morning of the 8th to resume bombardment about 08:00, one section again hit the Lingayen area. About ten minutes later a destroyer standing close inshore and a spotting plane from a battleship reported that Filipinos were forming a parade, complete with United States and Philippine flags, in the town of Lingayen. The fire was shifted to more westerly targets while leaflets were quickly prepared instructing the Filipinos to clear the area. A spotting plane dropped the leaflets and the paraders dispersed. Bombardment started again as soon as the area seemed vacated. The reasons for resuming the bombardment of Lingayen and its environs in the face of this friendly demonstration ashore are unknown, especially since neither underwater demolition teams nor spotting planes had discovered any signs of Japanese activity in the area. The town, at least, seemed safely in the hands of the Filipinos. The most obvious explanation is that erroneous intelligence, having indicated that strong defenses would be encountered in the area, made it incumbent upon Admiral Oldendorf to continue the bombardment whether he wanted to or not. Too much was at stake to take a chance. The Filipinos in the Lingayen area could hardly have been pleased as they saw their homes and public buildings damaged or destroyed by what to them must have seemed an unnecessary bombardment. It seems a tribute both to the Filipinos and to the prewar administration of the United States in the islands--as well as a severe and obvious indictment of Japanese occupation policies--that the people of the Philippines took such adversities in their stride, not permitting personal resentments to overcome judgment and loyalty.

Throughout the rest of 8 January, bombardment of the landing beach areas continued without incident. Practically no military installations or targets were found in the Lingayen town and airstrip area, and relatively few were discovered in the San Fabian region. The San Fabian bombardment vessels ran out of targets by 1530 and moved back up the gulf to strike the San Fernando area for another forty-five minutes, completing the task that the Japanese kamikazes had interrupted on the 6th. The Lingayen area ships had long since ceased their firing for the day. Thus ended preliminary bombardment operations. The heavy bombardment of the San Fernando sector on the 6th aroused great anxiety in General Yamashita's headquarters. An enemy landing in that sector would fall north of the main positions of the 58th Independent Mixed Brigade and create serious danger of a thrust toward Baguio over the Bauang-Naguilian Highway. The only means of meeting this potential threat was to change the planned employment of the 19th Division. The division was still in the San Fernando-Naguilian area due to postponement of its scheduled movement inland, and intense enemy air activity over the whole Lingayen area made it improbable that it could move in any case. Consequently, on 7 January, the Area Army ordered the division to assume responsibility for the defense of the sector north of a line running through Santiago, Magungunay, Mt. Bilbil, and Asin. Its main strength was to be concentrated between Naguilian and Baguio.

With preliminary operations finished, Kinkaid’s amphibious attack convoys arrived at the entrance to Lingayen Gulf around 04:00 on January 9. As the amphibious ships began landing operations, the fire support vessels of Admirals Barbey and Wilkinson positioned themselves for final pre-assault bombardment. In support of these efforts, McCain struck Formosa, destroying 47 Japanese aircraft, sinking seven ships, and damaging eleven others. Throughout the week, the fast carriers conducted a total of 3,030 offensive sorties, dropping approximately 700 tons of bombs at the cost of 86 aircraft. Pleased with the results of the anti-kamikaze operation, Nimitz finally permitted Halsey to launch a major raid into the South China Sea, codenamed Operation Gratitude. Meanwhile, back in Luzon, the pre-assault bombardment commenced at 07:00, gradually shifting fire from the landing beaches to the flanks of the assault area. At 09:00, the first amphibious vehicles began their approach from a departure line about 4,500 yards offshore, while rocket-armed landing craft and aircraft bombarded the beaches.

The landing beaches of the 14th Corps were located across the middle of Lingayen Gulf's southern shores and centered on Lingayen airstrip and the nearby grounds of the capitol of Pangasinan Province. In peacetime one would have considered the shore line a beautiful swimming beach, a magnificent strand of firm sand stretching eastward almost 9 miles from the mouth of the Calmay River to the mouth of the Dagupan. The east bank of the Dagupan, which enters the gulf midway between Lingayen and San Fabian, delineated the boundary between the 14th and the 1st Corps, and bridges over the Dagupan were expected to provide the first easy means of contact between the two corps. Since there was a gap of over 6 miles between the 1st Corps' westernmost beaches and the 14th Corps' easternmost, it was imperative that the Dagupan crossings be seized without delay. Planners anticipated that inasmuch as 1st Corps troops would be a mile or so closer to the river at the moment of landing they would be the first to reach the bridges, but it was 14th Corps' responsibility to relieve 1st Corps at the crossings as soon as possible. The 37th Division was to drive toward the Dagupan, while the 40th Division would make a quick thrust west and northwest to Port Sual and Alaminos. Port Sual, located at the southwestern corner of Lingayen Gulf, and at the western extremity of the Army Beachhead Line, possessed some importance as the site of minor port facilities. Alaminos, about twelve miles northwest of Port Sual, lay inland on the Bolinao Peninsula. Early capture of road junctions at Alaminos would help forestall Japanese attempts to organize counterattacks against the 6th Army's right flank.

In contrast, the beaches assigned to the 1st Corps were more widely spaced. The units of the 6th Division were scheduled to land on the Blue Beaches, located midway between the Dagupan River mouth and that of the Bued River. The 103rd Regiment was to land on White Beach 3 at San Fabian, while the 169th Regiment would land on White Beach 2, nearly two miles to the northeast. Additionally, the 2nd Battalion of the 172nd Regiment was set to land on the nearby White Beach 3. Fortunately for the American forces, they encountered minimal resistance as the initial waves approached the shore, facing only some challenges from the ebb tide. Shortly after 09:30, the 1st and 20th Regiments landed on the Blue Beaches, with the 1st Regiment quickly securing the mouth of the Bued River and advancing three miles inland to Mangaldan, while the 20th Regiment moved toward Dagupan. Meanwhile, Wing’s regiments landed on their designated beaches to the northeast but faced harassment from snipers, artillery, and mortar fire from Lieutenant General Nishiyama Fukutaro’s 23rd Division. However, the assault waves of the 14th Corps moved more slowly than expected, reaching the western beaches only by 09:40. The 185th Regiment captured Orange Beach, the 160th Regiment took Green Beach, the 148th Regiment secured Yellow Beach, and the 129th Regiment landed unopposed on Crimson Beach.

After landing on the beaches, the 1st Battalion of the 185th Regiment marched to the Agno River's mouth. Meanwhile, the 40th Reconnaissance Troop established a roadblock on the main road, just three miles east of Port Sual. The 2nd Battalion of the 185th Regiment advanced directly inland through Lingayen, successfully crossing the Calmay River and an east-west segment of the Agno River. Similarly, the 160th Regiment crossed the Calmay and assembled nearly four miles inland. The reserve 2nd Battalion of the 108th Regiment landed at Lingayen, while the 148th Regiment moved straight inland, crossing both the Calmay and Dagupan Rivers toward San Carlos. The 129th Regiment entered Dagupan and crossed the Patan River to reach Calasiao, with its 3rd Battalion eventually extending the line to connect with the 148th. By the end of the day, Griswold had established a beachhead stretching northwestward from Calasiao for nearly twenty miles to the outpost near Port Sual. At the same time, Wing's units encountered the most significant resistance from three tiers of ridges that overlooked the 43rd Division's beaches from the north, northeast, and east. 

The 43rd Division had the most hazardous and difficult S-day tasks. On the division's left low hills lay scarcely three-quarters of a mile inland from WHITE Beaches 1 and 2. Stretching northward, and coming still closer to Lingayen Gulfs eastern shore, a first line of low, grass-covered hills formed a somewhat broken ridge line, the seaward slopes of which grew steeper as the hills proceeded north along the coast. Beyond this first range, which averaged less than 250 feet in height, lay another, more irregular north-south ridge that rose to 350 feet. Still further east--a little over three miles inland--was yet a third steep-sided, grass-covered ridge line, this one averaging around 600 feet high. The three tiers of ridges overlooked the 43rd Division's beaches from the north, northeast, and east. They provided the Japanese with natural defensive terrain, excellent observation, good positions from which to deliver direct fire on the beaches, and cover behind which there was protection from the essentially flat trajectory of naval support fires. Moreover, the ridges were close to assembly areas further inland that could provide large Japanese forces with cover and concealment. In a single night the Japanese could move considerable strength from these assembly points into the tiers of hills to launch a counterattack against the 6th Army's left.

While the 2nd Battalion of the 172nd Regiment advanced toward Hill 247, the 169th Regiment moved eastward, successfully reaching Binday and extending its lines north along the gentle slopes leading to Hill 470. Meanwhile, the 2nd Battalion of the 172nd Regiment quickly secured the barrios of Mabilao and Alacan, ultimately capturing Hill 247 despite scattered resistance. As small arms and mortar fire intensified, combat patrols advanced toward Hill 385, coinciding with the remainder of the 172nd coming ashore.

Finally, the 103rd Regiment took control of San Fabian without facing any opposition and then advanced generally south and southeast toward Hill 200, halting just north of San Jacinto by the end of the day. While the assault units of the 1st Corps successfully landed by dusk on January 9, Swift’s advance was not as deep as Griswold’s, leaving several dangerous gaps between his units. Throughout the day, the Japanese launched sporadic kamikaze attacks on the Luzon Attack Force, causing significant damage to the battleship Mississippi, hitting the cruisers Columbia and Australia again, and damaging one destroyer escort. Meanwhile, friendly anti-aircraft fire resulted in numerous casualties aboard the battleship Colorado. In response to the enemy landings, Yamashita decided to deploy the 2nd Tank Division to the Agno River line near Tayug, where the armored units were to execute a counterattack from the northern flank if the enemy overextended. He also sent five battalions under Lieutenant-General Tsuda Yoshitake to secure the Cabanatuan area, ordered Lieutenant-General Okamoto Yasuyuki’s 10th Division to position elements in the Triangle Hill and Tayug sectors to counter a potential enemy advance from Lingayen toward San Jose, stationed the majority of the 11th Independent Regiment at Bongabong, and directed the Noguchi Detachment to move from Bicol to the Manila area. During the night, the 12th Surface Raiding Regiment, based at Port Sual, attempted to disrupt further enemy landings with a full-scale suicide boat attack on ships near the beachhead. Taking advantage of the element of surprise, the small explosive-laden boats approached undetected but only succeeded in sinking one LCI and damaging eight other vessels.

In other areas, increased guerrilla activities and Allied airstrikes in northern Luzon had nearly stopped the Japanese from collecting and transporting vital food supplies to the critical defense zones within the Baguio-Mankayan-Bambang triangle. This disruption would hinder the 14th Area Army's capacity to conduct a prolonged defensive campaign. Although plans for a desperate, full-scale counteroffensive were developed, Yamashita decisively rejected this strategy, instead ordering the 2nd Tank Division to cancel its intended counterattack and regroup at Lupao, approximately eight miles northwest of San Jose. Meanwhile, on January 10, Griswold’s forces continued their advance inland: the 185th Regiment moved west toward Port Sual; the 160th Regiment progressed southward about eight miles; the 148th Regiment quickly advanced to San Carlos; and the 129th Regiment pushed forward to Malasiqui, where the 14th Corps faced enemy resistance for the first time since the landing. Additionally, the reserve 108th and 145th Regiments successfully landed on the Lingayen beaches. To the north, the 6th Division shifted generally south and southeast, covering about four miles across flat, dry, open farmland, and by nightfall, it secured a front of approximately seven miles from west to east. As they continued northeast, the 103rd Regiment expanded its front, with its 2nd Battalion advancing toward Manaoag while the other two battalions moved to the area northwest of Hill 200. Lastly, the 169th and 172nd Regiments encountered the most intense resistance thus far, providing an early glimpse of the challenges that would impede the 43rd Division for the upcoming month.

The 1st Battalion, 169th Regiment, supported by close artillery and mortar fire, engaged in combat along the steep, grassy slopes of Hill 470, ultimately capturing the summit by nightfall. Meanwhile, the rest of the regiment advanced across the Bued River toward Hills 355 and 318, but halted near the river due to heavy artillery, mortar, and machine-gun fire. To the north, the 172nd Regiment cleared Hill 385 and then moved toward Hills 351 and 580, gradually advancing along the southern section of the third ridge line, which was located inland from the beaches. Additionally, its 1st Battalion progressed two miles along the graveled coastal road and conducted patrols along the ridge crest. By nightfall, Krueger had determined that the 6th Army Reserve should be deployed in the 1st Corps’ area, as outlined in the pre-assault plans, due to the significant resistance faced by the 43rd Division. He suspected that the apparent lack of enemy resistance to the west was a trap, designed to lure the 6th Army into overextending its lines, making its flanks susceptible to a counterattack from the east. Fortunately for the Americans, Tominaga’s kamikaze attacks began to diminish in the days following the landing, with an attack on January 10 resulting in damage only to the destroyer escort LeRay Wilson and one transport ship. The next day, the 43rd Division continued to face challenges in Luzon. The Japanese mortar and artillery fire along the 172nd’s eastern front was so severe that Wing decided to shift the regiment's attack direction from east to north, resulting in minimal progress as they redeployed to strike toward Hills 351 and 580 from Hill 470. Additionally, the reserve 158th Regiment was landed to relieve the 1st Battalion, 172nd Regiment, on the coastal road.

Looking southeast, the 169th Regiment nearly encircled Hill 318. However, despite receiving maximum support from Durgin’s carrier aircraft, naval gunfire, and division artillery, they were unable to dislodge the Japanese forces, who had entrenched themselves in the hillside. Meanwhile, Griswold’s advance inland to secure the Army Beachhead Line continued to progress well on January 11. On the 11th the 185th Infantry patrolled and consolidated its positions on the west flank, suffered no casualties, killed 5 Japanese, and captured another. Early in the morning a Chevrolet sedan of 1940 or 1941 vintage, occupied by two Japanese, came calmly down the coast road from the direction of Port Sual. Obviously unaware that Company C, 185th Infantry, maintained a roadblock on the highway, the Japanese practically ran into the American outpost before they realized their situation. Before they could recover from their surprise and consternation, both Japanese were dead, and Company C had acquired some luxurious transportation.

Meanwhile the 160th Regiment reached Aguilar, a road junction already held by Filipino guerrillas. The 108th Regiment closely followed the 160th, and the 148th Regiment established a line from Dumpay westward for four miles to Bacnar, with patrols extending further south to Urbiztondo and Bayambang. By the end of the day, the 14th Corps had either occupied or outposted nearly all the territory within the Army Beachhead Line in its sector. However, with Swift’s units unable to keep up with the advance southward, Griswold faced the risk of exposing his eastern flank if he continued to push forward. Therefore, the 1st Corps needed reinforcement to prevent widening the gap along the corps boundary. As a result, the reserve 63rd Regiment and the 13th Armored Group were deployed in the San Fabian area, while the 6th Ranger Battalion, which had landed at Blue Beaches the previous day, moved to the Dagupan area. Additionally, Major-General Charles Mullins’ 25th Division began to assemble between the Agoi and Patalan Rivers. Despite these developments, casualties had been significantly lower than expected, with 55 men killed and around 185 wounded, primarily from the 43rd Division. Japanese casualties in ground operations were also relatively low, with American estimates suggesting between 150 and 200 Japanese killed.

Meanwhile, Task Force 38 made its way into the South China Sea via the Luzon Strait on January 10, accompanied by the refueling group. Although poor weather conditions thwarted a scheduled refueling on that day, Task Force 38 was completely fueled by noon on January 11 and prepared to carry out Halsey’s ambitious raid.

As Allied forces prepared for a major assault on Luzon, kamikaze attacks intensified, leading to fierce battles and unexpected challenges, but Filipino resilience shone through despite devastation. On the shores of Lingayen Gulf, American forces launched a strategic landing, facing minimal resistance, but soon encountered fierce Japanese counterattacks as they advanced inland.

- 163 - Pacific War Podcast - Aitape-Wewak Campaign - December 31 - January 7 - , 1944

Last time we spoke about the Victory at Leyte. In the Ormoc Valley, General Krueger's forces pushed the Japanese into a retreat toward Palompon. As the Americans advanced, they faced entrenched enemy positions and challenging terrain. On Christmas Day, the 77th Division successfully captured Palompon, cutting off the Japanese's main route. General Suzuki, forced to relocate his headquarters, prepared for a counteroffensive. Despite fierce resistance, American troops continued to push forward, eliminating remaining Japanese units and securing strategic positions along the coast as the year closed. As General Eichelberger's 8th Army took command of Leyte Island, the 77th Division relieved other units in preparation for future operations. Meanwhile, American forces faced fierce resistance while securing strategic positions on Samar and Mindoro. Despite enemy air assaults, they successfully disrupted Japanese plans, including a failed counter-landing. In Bougainville, Australian troops engaged in intense fighting, capturing Pearl Ridge after fierce battles. Their victory provided a crucial vantage point for future offensives, marking a significant moment in the campaign.

As previously discussed, General Dunckel’s task force successfully invaded Mindoro. Despite recent enemy efforts to reclaim control of the island, the Americans managed to establish airfields that enabled land-based aircraft to target specific locations on Luzon while also safeguarding the assault and resupply ships heading to Lingayen Gulf. This location was chosen because it had direct access to Luzon's key military objective, the Central Plains-Manila Bay region, and it featured the best and most extensive landing beaches on the island. With General Eichelberger’s 8th Army taking charge of Leyte and Mindoro, General Krueger’s 6th Army was assigned to capture and secure a beachhead at Lingayen Gulf and then advance south through the Central Plains to seize Manila and open Manila Bay. Furthermore, air and logistical bases would be established on Luzon to support future operations against Japan, and the legitimate government of the Philippine Commonwealth would be reinstated in its capital. For Operation Mike I, the reconquest of Luzon island, the Southwest Pacific's intelligence estimates concerning Japanese strengths, dispositions, capabilities, and intentions on Luzon were reasonably accurate from the start of planning. The abundance of information must be attributed in large measure to the efforts of guerrillas on Luzon, an island that was becoming a veritable hotbed of guerrilla resistance, both American-led and Filipino-led. Carefully nurtured by MacArthur's headquarters, especially after mid-1943, the guerrilla organizations had grown steadily in strength and effectiveness not only as sabotage units but also as valuable sources of information. The Leyte invasion in October 1944 gave great encouragement to the guerrillas, who redoubled their efforts in preparation for the invasion of Luzon, which they realized could not be too far off. Throughout 1944 supplies of all types had been sent to the guerrillas, first by submarine and later by airdrop and clandestine inter-island transportation. After the establishment of the Allied base on Leyte, the flow of supplies increased by leaps and bounds. The guerrillas themselves established a network of radio communications that soon came to be sustained and, to some extent, controlled by MacArthur's headquarters, which also sent into Luzon special intelligence parties to develop new sources of information and provide guerrilla efforts with more effective direction. In the end, one of the major difficulties Southwest Pacific intelligence agencies had was not obtaining information from Luzon but rather sifting the plethora of guerrilla reports, which attained every conceivable degree of accuracy and detail. Once sifted, the information had to be evaluated and correlated with that received from other sources such as radio intercepts, captured documents, and prisoner interrogations.

MacArthur allocated the majority of his Army's ground combat and support forces, most of General Kenney's Allied Air Forces, and nearly all of Admiral Kinkaid's Allied Naval Forces ships and landing craft. He needed to ensure enough forces to defeat a strong Japanese garrison, secure a beachhead against potential fierce resistance, advance south through the Central Plains against expected strong defenses, defend the beachhead from anticipated counterattacks, and secure the Central Plains-Manila Bay area within four to six weeks.

Krueger was assigned command of the 1st Corps, which included the 6th and 43rd Divisions, as well as the 14th Corps, comprising the 37th and 40th Divisions. In reserve were the 25th Division, the 11th Airborne Division, the 158th Regiment, the 13th Armored Group, and the separate 6th Ranger Battalion. Supporting these units were 13 nonorganic field artillery battalions of various calibers, two chemical mortar battalions, two additional tank battalions, the majority of five engineer boat and shore regiments, four amphibious tractor battalions, and 16 engineer aviation battalions, totaling approximately 203,000 personnel, of which 131,000 were classified as combat troops. 

By the way, since I mentioned one, for those curious, a Chemical Mortar Battalion were US Army non-divisional units attached to infantry divisions during WW2. They were armed with 4.2-inch chemical mortars. Chemical shells were on standby during WW2, to be used in retaliation should the enemy employ chemical weapons first. Toxic agents such as phosgene or mustard gas could be used as well as white phosphorus. Additionally, Eichelberger’s 8th Army was tasked with conducting a subsidiary landing on Luzon with the 11th Corps, which included the 32nd Division and the separate 112th Cavalry and 503rd Parachute Regiments. Furthermore, MacArthur designated the 33rd and 41st Divisions as General Headquarters Reserve and made plans to send the 33rd and 38th Divisions, along with the 1st Cavalry Division and the 19th and 34th Regiments, to Luzon within two months. Krueger’s plan for the Lingayen assault, set for January 9, involved an amphibious attack on the southern beaches of the gulf, which were lightly defended but presented numerous obstacles that impeded maneuverability. Aiming for a swift landing with a robust force to achieve tactical surprise, Krueger opted for a broad front assault, with Major-General Innis Swift’s 1st Corps landing on the eastern beaches near San Fabian and Major-General Oscar Griswold’s 14th Corps on the western beaches facing Lingayen town. Each corps would land two divisions side by side, with one regiment from each division held in floating reserve.

The initial missions of the two corps were the same: to capture the beachhead area within their designated zones, protect the flanks of the 6th Army, and maintain communication with one another. Both corps were also ready to advance quickly inland to secure a crossing over the Agno River, which would serve as the starting point for the final push south toward Manila and Manila Bay. Anticipating some congestion on the beaches, Krueger decided to keep the 25th Division, the 158th Regiment, and the 13th Armored Group afloat until January 11. On that date, the 158th would land on the extreme left of the 1st Corps to block the coastal corridor along the eastern shore of the gulf, preventing any Japanese counterattacks from the north. Similarly, the 25th Division and the 13th Armored Group were also ready to be deployed in Swift’s area for both defensive and offensive operations. To facilitate the amphibious assault, Kinkaid took direct command of Task Force 77, which comprised the entire 7th Fleet, along with some Australian and Dutch vessels assigned to MacArthur, as well as warships borrowed from Admiral Nimitz’s Pacific Ocean Areas. Kinkaid organized his Luzon Attack Force into several combat components, with Admiral Barbey’s Task Force 78 tasked with landing the 1st Corps and Admiral Wilkinson’s Task Force 79 responsible for the 14th Corps. Admiral Oldendorf once again led the Bombardment and Fire Support Group, which included six battleships and five heavy cruisers, while Admiral Berkey headed the Close Covering Group of four light cruisers. This time, Kinkaid’s escort carriers were under the command of Rear-Admiral Calvin Durgin, who had a total of 17 escort carriers to provide convoy protection, conduct airstrikes on the target area alongside pre-assault minesweeping and bombardment, and offer close air support for ground operations until that responsibility was handed over to Kenney's land-based aircraft.

Admiral Halsey’s 3rd Fleet would once again play a crucial role in the operation by targeting enemy airfields, while also being ready to provide direct support if the Japanese gathered enough surface forces to initiate a significant naval confrontation. Meanwhile, Kenney’s Allied Air Forces were tasked with safeguarding the convoy’s sides and rear through overwater reconnaissance and attacks on enemy facilities in the southern Philippines and the Dutch East Indies, with General Whitehead’s 5th Air Force responsible for carrying out most of these missions. Additionally, army aircraft were to protect convoys traversing central Philippine waters and offer air support for ground operations whenever possible. To complement Operation Mike I, a comprehensive deception strategy was in place, aimed at diverting the enemy’s attention to a potential Allied threat against Formosa and southern Japan through naval activities in nearby waters. Consequently, Admiral McCain’s Task Force 38 launched its initial strikes in support of the Lingayen operation on January 3 and 4. Although poor weather conditions hindered attacks on Formosa and the Ryukyu Islands, they still achieved moderate success. MacArthur also aimed to mislead the Japanese into believing that the primary focus of any Allied offensive on Luzon would be directed towards western Batangas or the Bicol Provinces. Therefore, on January 1, Company I of the 21st Regiment advanced on Bongabong along Mindoro's east coast, beginning the clearance of northeastern Mindoro. The next day, Company B of the 503rd Parachute Regiment started operations on the northwestern coast, moving towards Mamburao. On January 3, Company K of the 21st Regiment landed without opposition at Buenavista on the southwestern shore of Marinduque Island and established positions to set up radar installations.

Meanwhile, other troops continued their advance toward Calapan, ultimately intercepting the recently landed enemy raiding unit at Pinamalayan on January 8, compelling it to retreat back to Calapan. Although some Japanese forces managed to reach Mansalay on the southeast coast of Mindoro and infiltrated overland toward San Jose, all attempts to raid enemy airfields were unsuccessful. Conversely, the 21st Regiment successfully captured Calapan on January 24, resulting in approximately 135 Japanese casualties, while the Americans incurred the loss of 1 soldier killed and 7 wounded. By the end of the month, Dunckel's forces had killed 170 Japanese and taken 15 prisoners, at a cost of 16 American soldiers killed, 71 wounded, and 4 missing, not including casualties from Japanese air attacks, which raised the Allied totals to 475 killed and 385 wounded.

Looking back to Luzon, General Yamashita was also focused on finalizing plans and preparations to counter the impending enemy assault. During the latter part of December, battle preparations proceeded with discouraging slowness. Overburdened transport facilities, enemy strafing and bombing attacks, guerrilla interference and an acute shortage of automotive fuel impeded progress in every direction. On the other hand, there were numerous indications that General MacArthur was virtually ready to strike. In the Batangas area, enemy air reconnaissance was conspicuously frequent, while the dropping of dummy parachutists and the activity of small surface craft along the coast also caused grave alarm in the 8th Division. Other reports indicated that guerrilla forces were beginning to assemble in the mountains east of Manila, and that enemy submarines were delivering arms to guerrillas in the Lamon Bay area.

Yamashita accurately predicted that the invasion would occur between January 10 and 20, targeting either the Batangas area or Lingayen Gulf. However, recognizing that he lacked sufficient forces for a decisive battle, particularly given the decimation of Japanese air power and the enemy's air superiority. As of the 1st of December the Japanese Army and Navy had probably had a combined air strength of some 500 planes in the Philippines, the bulk of them based on Luzon. This strength had been largely destroyed by Allied air strikes in support of the Mindoro operation and during Japanese air attacks against Mindoro-bound convoys and the Mindoro beachhead area. By the 20th of December, the Japanese Naval Air Service in the Philippines had no more than 30 planes, and the Japanese Army Air Force was down to approximately 100 first-line combat aircraft. About that date, some 50 naval planes flew to Luzon from Formosa to renew attacks against Mindoro, and shortly thereafter, it appears, a few Army aircraft also came down from Formosa or the home islands to reinforce Luzon. Many of these planes were lost during continued attacks against Mindoro until, by 31 December, the Japanese had probably no more than 150 operational aircraft left on Luzon, and about a third that many on other fields in the Philippine archipelago, for a total of about 200. Yamashita planned to execute a coordinated delaying strategy, launching local counteroffensives only when conditions were favorable. This approach aimed to deplete enemy resources and buy valuable time to reinforce Japanese defenses in Formosa and the Ryukyus. Consequently, on December 19, Yamashita finalized a new operational outline that established two forces: one to cover northern Luzon and the other for central and southern Luzon.

The plans outlined an initial strategy for the forces defending coastal regions to inflict significant damage on the enemy during their landing. This would be followed by delaying actions aimed at hindering the capture of crucial inland communication hubs and airfields. The final phase would involve a sustained last stand in the three mountainous areas previously identified as zones of ultimate resistance. To delay further enemy operations against Formosa and the Ryukyus, Yamashita decided to strengthen the northern sector, as its mountainous terrain and limited access routes from the central Luzon plain offered the best tactical conditions for prolonged resistance. As a result, Southern Luzon would be nearly stripped of troops to reinforce the second-largest concentration of forces in the mountains east of Manila. Yamashita positioned the 103rd Division in the Aparri coastal area, with three battalions stationed on the northwest coast; the 23rd Division, along with the 58th Independent Mixed Brigade, near the eastern shore of Lingayen Gulf; the 10th Division in the San Jose, Umingan, and Natividad sectors, along with the 11th Independent Regiment at Baler and Dingalan Bays; the 2nd Tank Division as a mobile unit in the Cabanatuan-San Miguel area, with the 6th Tank Regiment in Manila; the Manila Defense Force responsible for Manila and the surrounding mountains, with a garrison on Corregidor and the 39th Regiment on the Bataan Peninsula; the 8th Division securing key communication points to the east and west of Lake Taal, as well as important coastal positions in Batangas; the majority of the 105th Division stationed in the critical area east of Manila, while the Noguchi Detachment continued to hold Bicol; and the 82nd Brigade occupying coastal positions in the Lamon Bay region.

Upon its arrival on Luzon, the 19th Division was tasked with gathering its main forces south of San Leon, while also deploying units to secure critical locations around Tuguegarao and Echague. Additionally, the 2nd Mobile Regiment and the newly landed 2nd Glider Regiment were ordered to bolster defenses in the Clark Field area, which was primarily protected by ground air units. However, by the end of the month, due to the slower-than-anticipated withdrawal of the 105th Division, Yamashita instructed the 8th Division to relocate its main forces to the region east of Manila, leaving only the 17th Regiment stationed in Batangas Province. Lieutenant-General Yokoyama Shizuo then took command of the Shimbu Group, which encompassed all forces in the southern half of Luzon, below a line approximately extending from Manila to Lamon Bay. That is gonna be it for the Philippines today as we now need to head over to the Aitape-Wewak region. 

In the coastal sector the 19th Brigade had moved forward in accordance with Stevens' orders of 26th November that it should relieve the 2/7th Commando Squadron, clear the enemy from the area west of the Danmap, and concentrate round Babiang and Suain in preparation for operations east of the river. A company of the 2/4th Battalion had therefore relieved the 2/7th Squadron at Suain and Babiang on the 29th and 30th November. In the next 16 days patrols clashed with small groups of Japanese on seven occasions, and killed 28 without loss to themselves. By 17th December the main body of the 2/4th Battalion was at Suain, with a company at Idakaibul and one at Babiang. 

In the second week of December, the squadron expanded its control by establishing outposts at Yasile and Yambes, from which they successfully repelled several minor Japanese attacks. On 11th December an enemy patrol approached the perimeter held by Byrne's troop at Yambes. The Australians held their fire until the Japanese were 35 to 50 yards away, killed 6 and, during the day, 2 more. There were patrol clashes that day and on the 13th. At 1.30 a.m. on the 15th an enemy force of at least 35 attacked. This time the Australians let the leading Japanese come to within three yards of the perimeter then fired with automatic weapons and threw grenades. After pressing the attack for a while the enemy withdrew, dragging away their wounded and about 10 dead. By mid-December, the commandos had advanced along the coastal sector to the Danmap, over 40 miles from Aitape and approximately 20 miles into the Torricellis, without encountering significant enemy forces. The majority of Lieutenant-General Mano Goro’s 41st Division was positioned south of the Danmap, with the reinforced 237th Regiment under Major-General Aotsu Kikutaro occupying forward positions between the Anumb and Danmap Rivers.

Following the defeat at the Driniumor River, General Adachi’s 18th Army implemented a strategy to minimize contact with the enemy. They positioned outpost forces for ambush and scattered their units across a broad area, especially in locations where they could cultivate food and regain their strength. Despite these measures, many soldiers faced hunger, malnutrition, and illness, and they often lacked essential modern military equipment. Meanwhile, on December 12, Stevens instructed the seasoned 17th Brigade, led by Brigadier Murray Moten, to relieve the 2/7th Squadron at Tong and conduct patrols south towards Mimbiok and Yanatong, southeast to establish a base at Musimbe, and east to set up a base at Musu. Subsequently, the 2/7th Squadron was to relocate to Makuir and scout a route through Chem to the Dandriwad River and Babiang, aiming to establish a forward base on the Danmap, about five miles east of Makuir. In line with this plan, Moten dispatched Major Ian McBride’s Piper Force, consisting of two companies from the 2/5th Battalion, which arrived at Tong on December 20. That day Major Goode of the 2/7th Squadron reported that, except for foraging parties, the area which he had been ordered to patrol had been cleared of the enemy. The squadron had killed 26 Japanese and lost two killed and five wounded; two attached Papuan police had been wounded. The squadron's headquarters were now moved to Lambuain and it began its new task: to clear the Walum area. Walum village was occupied on 30th December after clashes in which several Japanese were killed. Documents captured by the squadron that day indicated that the main enemy line of communication from the coast to Balif was via Walum- Womisis-Womsak. At the same time, Piper Force occupied Musimbe and Musinau, coinciding with the arrival of the rest of the 2/5th Battalion in the Yambes area. Meanwhile, Stevens ordered the 19th Brigade to seize the Abau-Malin line and eliminate the enemy at the Danmap. On December 14, Martin sent the majority of the 2/4th Battalion to cross the river, with one company successfully fighting through Lazy Creek to reach Rocky Point.

As the other companies assembled, the 2/8th Battalion began its advance into the foothills to establish a forward base at Idakaibul and move towards Malin. Patrolling from Lazy Creek the 2/11th had two sharp clashes with the enemy force west of Niap on 30th and 31st December, three Aus- tralians and 11 Japanese being killed. At Matapau village, early on 2nd January, from 30 to 35 Japanese attacked the perimeter of Captain Royce's company. Artillery fire was brought down and the Japanese with- drew leaving six dead. This was the beginning of five days of sharp fighting against Japanese who seemed determined to stop the advance along the Old German Road. As soon as the enemy's attack had been repulsed Royce's company pushed forward along the road to a spur whence the artillery observer, Captain Lovegrove, might direct fire. A platoon crossed the little Wakip River at 10.20 a.m. but came under fire from Japanese on the steep-sided spur. The infantry withdrew and accurate artillery fire was brought down. At 2.10 p.m. the spur was occupied and from it Lovegrove directed fire on a pocket of Japanese so close that he had "to almost whisper his orders into the phone". In the day 14 Japanese were killed, and two Australians killed and five wounded, of whom four remained on duty. Next day, and on the 4th and 5th, there was sharp fighting round the spur and towards Niap, and on the 6th, after a strike by 11 bombers and a bombardment by the artillery, a platoon attacked across the Wakip but was held by the resolute enemy pocket at Niap.

On January 7, the Japanese defense was finally breached when three tanks broke through the beach and entered the town, followed by infantry. The next day, the leading company of the 2/8th Battalion entered Malin without facing any opposition. However, the 2/11th Battalion struggled to advance towards Doreto Bay, as the determined defenders repelled their attacks for another ten days. On January 18, a company executed a successful flanking maneuver through the foothills to Nimbum Creek and eventually positioned itself south of Abau, capturing the town two days later. Meanwhile, Lieutenant-Colonel Alfred Buttrose had sent one company to assault Perembil and secure the Musu area, while another advanced through Sumul towards Maharingi, and McBride’s company at Musinau moved eastward to patrol deep into the south. On January 3, the Australians unexpectedly drove a strong force of the 238th Regiment from Perembil, though they had to fend off several counterattacks in the following days. Continuing their advance, Asiling fell on January 9, followed by Samisai two days later, and another company secured Maharingi by January 15. Now, it is time to return to the Marianas to prepare for the next missions of General Hansell’s 21st Bomber Command. 

The United States military took steps to improve Saipan's defenses after the damaging raids of November 27. In a frantic effort to detect future intruders, Admiral Hoover stationed two destroyers 100 miles northwest of Saipan to provide early radar warning, and an AN/TPS-3 radar was rushed to Saipan from Oahu by air. The destroyers in some instances gave ample warning, but on other occasions the enemy planes still managed to come in unannounced. Arnold became frustrated that the microwave early warning radar set still was not in use; and on December 3 Admiral Nimitz ordered that the highest priority be given to installing the radar. Despite this, it still was not ready until after the conclusion of the Japanese air campaign. Two B-24 Liberator bombers fitted with air-to-air radar sets were also dispatched to Saipan. This was the first use of airborne warning and control aircraft by the United States, but they were not used in combat.

To maintain pressure on the enemy following the San Antonio strikes, he conducted a night radar mission with 30 Superfortresses on November 29, although it was unsuccessful. This mission was part of his preparations for a daylight attack on the Nakajima Aircraft Plant in Ota, scheduled for December 3. By D minus I weather reports were forbidding: at bombing altitudes over Ota, winds were reaching velocities of I 80 miles per hour or more. At 01:30 on the 3d it was decided that the only hope for the day was to go back to Musashino where visible bombing might be possible." Crews had already been briefed twice for the target; the 73d Wing hurriedly cut field orders and by 0945 eighty-six bombers were heading for Tokyo. Seventy-six got over the city to find clear weather but high winds; 59 planes bombed visually from a mean altitude of 28,700 feet with poor results.

Out of this mission, six bombers were lost, and another six were damaged, resulting in just 26 bombs hitting the plant area, causing minimal damage to buildings and equipment. Once again, the strike was disappointing. Musashi's records indicate that twenty-six bombs fell in the plant area with some small damage to buildings and equipment and almost none to machinery; Japanese casualties were moderately high. Strike photos, the command's only source of information, seemed to show even less damage, and for these slight results the command had paid dearly, with six B-29's lost and six damaged.

In response, on December 7, several Japanese aircraft, including two squadrons of Ki-67 bombers, launched a coordinated attack from both high and low altitudes, destroying three B-29s and damaging 23 others. This assault was observed by Lieutenant-General Millard Harmon, the commander of Army Air Forces in the Pacific, who had been sent by Nimitz to coordinate an extensive attack on Iwo Jima’s installations using both air and surface forces. On December 8th, at 0945 twenty-eight P-38’s swept over the island, followed at 1100 by the B-29’s and at noon by the Liberators. Hoover’s crusiers began seventy minutes of shelling at I 347. The bomb load carried by the planes forcefully illustrated the difference in performance between the heavy and very heavy bomber at 725 miles tactical radius: the 62 B-29’s dropped 620 tons, 102 B-24’s only 194 tons.” All told, enough metal was thrown to produce a good concentration on Iwo’s eight square miles, but because the bombers had been forced to loose by radar, results, so far as they could be judged from photography-handicapped, like the bombing, by adverse weather-were much less decisive than had been expected. Eyen so, the enemy’s raids on Saipan stopped until 25 December. Although the results were not as decisive as hoped, the enemy raids on Saipan were temporarily halted. On December 13, Hansell sent 90 Superfortresses to bomb the Mitsubishi Aircraft Engine Works in Nagoya. 

The choice for primary visual target was the Mitsubishi Aircraft Engine Works at Nagoya, and the same company’s aircraft works was named as radar target; strays, it was hoped, would spill into crowded Nagoya, Japan’s second city and an industrial center of great importance. The engine works, still in top priority for 21st Bomber Command, lay in the northeast section of Nagoya, about two and a half miles from Nagoya Castle. The plant was considered by the JTG as a single target though it actually consisted of three separate but closely related units of the vast complex comprising the Mitsubishi Heavy Industries, Ltd.: I) the No. 2 Engine Works, responsible for research, design, and manufacture of prototype engines; 2) the No. 4 Engine Works, which between 1939 and 1945 manufactured 44,004 engines, the most important model being the Ha-102, a 1,000-horsepower motor used on the Nick and Dinah 2; and 3) the No. 10 Engine Works, which furnished castings and forgings for all Mitsubishi engine plants. On the 13th, the 73d Wing was able to get ninety bombers up, most of them carrying ten 500-pound GP’s but one squadron from each group loaded with incendiary clusters. As on previous missions, a number of planes failed to reach the primary target: sixteen B-29’s aborted and three bombed targets of opportunity. Japanese resistance was lively and, in all, four B-29’s were lost, thirty-one damaged.

Despite significant losses, the recent bombing campaign demonstrated improvement, resulting in the destruction of an assembly shop and seven auxiliary buildings. Additionally, damage was inflicted on an assembly shop, a prototype engine-manufacturing facility, two other shops, and 11 buildings, leading to approximately 351 casualties. The bombing, if of less than pickle-barrel precision, showed improvement. Strike photos indicated that 16 per cent of the bombs dropped had fallen within 1,000 feet of the aiming point and that 17.8 per cent of the roofed area had been destroyed?’ Although this in itself was encouraging, had intelligence officers been able to read from their photos the whole story, there would have been even more optimism on Saipan. At the No. 4 Engine Works an assembly shop and 7 auxiliary buildings were destroyed, and an assembly shop and 11 buildings were damaged; at the No. 2 Engine Works a prototype engine-manufacturing shop and 2 other shops were damaged; and personnel losses ran to 246 killed and 105 injured. 

For the first time, the 21st Bomber Command made a noticeable impact on the aircraft industry, prompting the Japanese to start relocating equipment to underground facilities. Plant officials calculated that the attack reduced productive capacity from 1,600 to 1,200 engines per month; after December 13 parts were no longer machined at No. 4 Engine Works, and engine production was limited to assembling parts on hand and those received from other plants. Mitsubishi officials had been considering the advisability of dispersing the Nagoya facilities ever since the fall of Saipan. After the strike of December 13 the transfer of equipment to underground sites began, but even at the end of the war the movement had not progressed far enough to allow production in the new plants.

Five days later, Hansell dispatched 89 B-29s to target the Mitsubishi Aircraft Works in Nagoya. The Mitsubishi Aircraft Works was the giant assembly plant which used most of the engines produced in the No. 4 Engine Works. Located on reclaimed land at the northeast corner of Nagoya harbor, it was, like the engine works, composed of three integrated plants: I) the No. I Airframe Works for research and experimental engineering; 2) the No. 3 Airframe Works, which built navy planes-Zeke and Jack fighters and Betty bombers; and 3) the No. 5 Airframe Works, which manufactured bombers and reconnaissance and transport planes for the army. Large, compact, and conspicuous, this complex offered an excellent visual target, and the proximity of the harbor's shore line made it suitable for radar strikes as well. On this 18 December attack many planes, as usual, failed to follow the flight plan so that only sixty-three planes bombed the primary target. Cloud cover was heavy and forty-four of these dropped by radar, to add considerably to the damage caused by an earthquake on 7 December. Though few bombs were plotted in the area, 17.8 percent of the roofed area appeared to have been destroyed. The No. 3 Works suffered extensive damage to the sheet-metal, heat-treatment, fuselage assembly, and final-assembly shops, and at No. 5, approximately 50 per cent of the total assembly area was damaged. Casualties, in dead and injured, amounted to 464. 

On December 22, Hansell was compelled to alter his tactics and initiated a daylight incendiary mission. Unfortunately, only 48 B-29s targeted Mitsubishi's engine works due to poor weather, resulting in minimal damage. The Nagoya mission on the next day, though using only incendiaries, was not in fulfillment of Norstad’s request; it involved only 78 bombers dispatched instead of IOO and it was planned as a daylight precision attack. The weather turned bad, however, and before the last formations were over Nagoya the target was covered by 10/10 cloud. Only forty-eight planes bombed the Mitsubishi plant and they had to drop by radar; strike photos were few and revealed little. Actually there was not much damage to reveal: 252 fire bombs fell in the area of the No. 4 Works, damaging a few buildings but hurting no machine tools and causing no loss to pruduction

On Christmas night, the newly renamed 6th Air Army, led by Lieutenant-General Sugawara Michio, launched its final significant assault on the Marianas, deploying 25 aircraft to bomb from both high and low altitudes. This attack resulted in the destruction of one B-29, serious damage to three others, and minor damage to 11. Overall, the Japanese had deployed over eighty planes over Saipan and Tinian, losing around 37, while managing to destroy 11 B-29s, seriously damaging 8, and causing minor damage to 35. Finally, on December 27, Hansell's last mission involved a return trip to Nakajima, where only 39 out of 72 dispatched B-29s caused little damage to the Musashi plant, although an incendiary attack unfortunately set a hospital on fire.

In a fierce battle for control, forces devised a strategy to defend coastal regions and key locations in Luzon. As troops repositioned, Australian commandos clashed with Japanese units, achieving victories despite challenges. Meanwhile, U.S. bombers targeted Japanese industrial sites, inflicting damage but facing heavy losses, marking a pivotal struggle in the Pacific theater.
