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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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