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

Picking up from last time. The Japanese naval-air counteroffensive against Admiral Spruance’s forces at Okinawa had been decisively defeated with minimal losses, allowing General Buckner’s 10th Army to proceed with the land offensive largely without interference. While General Geiger’s Marines advanced toward the sparse Japanese defenses in northern Okinawa, General Hodge’s 24th Corps in the south encountered the main enemy line of resistance centered around the Shuri fortified zone. Initially, the 32nd Army had declined to launch a land counteroffensive in conjunction with Operation Ten-Go and the Yamato’s suicide attack, fearing that the Americans might execute another amphibious landing at Machinato while the Japanese wasted their strength in a futile effort to reclaim the airfields. However, pressure from Tokyo and Formosa compelled General Ushijima to resume planning for this operation. Ultimately, it was decided that instead of initiating a broad counterattack, the Japanese would deploy a brigade-strength force overnight on April 12 to breach the American lines and advance approximately six miles. If successful, this would be followed by a general attack. Accordingly, Colonel Yoshida Masaru’s 22nd Regiment was assigned to the 62nd Division and assembled northeast of Shuri, tasked with attacking through enemy lines east of the Ginowan Road and advancing toward Shimabuku. To bolster this offensive, General Fujioka was also instructed to deploy three reserve battalions for a three-pronged attack from the west aimed at Chatan. However, Colonel Yahara, 32nd Army operations chief, strongly opposed the counterattack plan, feeling that it was not in keeping with the army's defensive mission and that it would waste men. He succeeded in getting the 1st Battalion of the 22d Regiment and elements of the 23d IIB cut from the counterattack force. He made a dire prediction that the infiltrating units, unfamiliar with the terrain in their attack sectors, would get lost, confused, and cut to pieces during a night assault. Taking a sidenote here, I read Yahara’s rather famous novel about his experience of the battle for Okinawa and I highly recommend it to all of you. It's a great insight into the perspective of the Japanese and how the leadership were beginning to change their mind on how to go about the war. Yahara, acting without Ushijima's knowledge, advised Fujioka to commit only four battalions to the attack, predicting it would inevitably fail. Meanwhile, the American offensive was still in progress. On April 9, as Major-General George Griner’s 27th Division landed at the Orange Beaches near Kadena, the ships of Colonel Waltern Winn’s 105th Regiment met with Admiral Blandy’s Eastern Islands Attack and Fire Support Group at the Kerama Islands, preparing to move to Tsugen Island overnight. Following a preliminary air and naval bombardment, which saw some Japanese mortar fire in response, Winn’s 3rd Battalion successfully landed on the morning of April 10. The Americans then advanced inland with light resistance, quickly securing the northern part of the island but failing to overrun the entrenched enemy positions in Tsugen village. The assault continued the next day against persistent opposition, but organized resistance gradually diminished, allowing the Americans to secure the rest of the island by nightfall, marking the conclusion of the Eastern Islands operation. On April 11, General Shepherd’s Marines continued to probe for the main enemy positions in northern Okinawa; the 1st Battalion, 22nd Marines patrolled eastward from their new base at Shana Wan, while the 29th Marines advanced toward Manna. Due to this progress, Buckner decided to fully merge Phases I and II, ordering the 77th Division to capture Iejima on April 16. To the south, Colonel Albert Stebbins’s 106th Regiment was attached to the 96th Division, moving toward that division's reserve area, while Colonel Gerard Kelley’s 165th Regiment relieved the 17th Regiment in the corps service area. Most significantly, General Bradley continued his attacks on Kakazu Ridge, with the 1st Battalion, 381st Regiment attempting to assault the western slopes but halted short of the ridge crest by determined defenders. At the same time, the 3rd Battalion, 383rd Regiment pushed up the northwest slopes of Kakazu Ridge but was also pinned down by intense Japanese fire. Simultaneously, following an intense artillery bombardment, the 1st Battalion of the 32nd Regiment finally succeeded in breaking into Ouki. However, additional reinforcements were thwarted by heavy Japanese fire, forcing the troops to retreat. With no further advancements, the 7th Division and the 382nd Regiment were relegated to patrolling and mopping up their designated areas over the next few days. At sea, Admiral Ugaki resumed his kamikaze assaults that day, damaging the carriers Essex and Enterprise, the battleship Missouri, and eight destroyers. However, his primary operation commenced on April 12, when he launched approximately 380 aircraft for a second mass Kikisui attack, primarily targeting Admiral Turner’s Task Force 51 west of Okinawa. Thanks to cryptanalysis warnings, Turner scrambled his own fighter planes, which successfully shot down 298 Japanese aircraft. Despite attempting numerous missions, Kanoya’s specially trained 721st Kokutai Jinrai-Butai “Divine Thunder” unit had so far failed to launch a single Ohka suicide rocket against the Americans. On April 12, however, eight Betty bombers would finally launch six Ohkas against the 5th Fleet, although five Betties never returned. At RPS-14, about 70nm northwest of Okinawa, a Zero plowed into Mannert L. Abele’s engine room at 14:40, its 500lb bomb exploding and leaving the destroyer dead in the water. One minute later an Ohka came screaming in at 575mph, slammed into Mannert L. Abele and exploded. She sank in five minutes, losing 97 dead. Mannert L. Abele was the first destroyer hit by an Ohka and the last sunk by one. Destroyer-minesweeper Jeffers, en route to assist Mannert L. Abele, observed a twin-engined bomber eight miles away drop a smoking “belly tank” that suddenly rocketed towards Jeffers “at terrific speed.” Numerous 40mm hits and hard maneuvering saw the Ohka miss Jeffers astern and disintegrate. Additionally 3 battleships, 14 destroyers, 2 destroyer minesweepers, and another landing craft were damaged. Meanwhile, Admiral Rawlings’ Task Force 57 was ordered to strike the Shinchiku and Matsuyama airfields in northern Formosa, and over the next two days, 48 Avengers and 40 fighters successfully attacked Shinchiku and Kiirun Harbor. On Okinawa, the 6th Reconnaissance Company captured Bise Saki with minimal resistance, while the 29th Marines faced significant opposition southeast of Manna near Mount Yae-Take, indicating where the main enemy forces were located. This prompted Shepherd to reposition the 3rd Battalion, 22nd Marines to Awa as his new divisional reserve. At the same time, Japanese guerrillas managed to retake Ishikawa, which they would hold for the following two days. Facing south, the 96th Division made another attempt to capture Kakazu but was once again thwarted by the determined defenders. By this time, approximately 5,750 Japanese soldiers were estimated to have been killed in the southern region, while the 24th Corps suffered losses of 451 men killed, 2,198 wounded, and 241 missing. In the afternoon of April 12, 1945, in Warm Springs, Georgia, while sitting for a portrait by Elizabeth Shoumatoff, President Franklin D. Roosevelt said: "I have a terrific headache." He then slumped forward in his chair, unconscious, and was carried into his bedroom. The president's attending cardiologist, Howard Bruenn, diagnosed a massive intracerebral hemorrhage. At 3:35 pm, Roosevelt died at the age of 63. His declining health had been kept secret from the public, leading to shock and sorrow worldwide upon the news of his death. Harry Truman, who was serving as vice president in 1945, succeeded FDR as president. Meanwhile, back in Okinawa, Fujioka initiated his counteroffensive after a heavy artillery bombardment, advancing his four battalions to secretly infiltrate the American lines. On the eastern front, the 22nd Regiment struggled to advance due to becoming disoriented in unfamiliar terrain. The night attacks suffered from several unexpected problems. Heavy shelling had changed the landscape, blasting away villages and thickets, so that even though night infiltrators knew their maps and thought they knew the terrain, they lacked the landmarks needed to tell them where they actually were. Moreover, frequent illumination shells forced the eyes of night infiltrators to adjust so many times that their capacity to adjust was lost. They became temporarily blinded and so were unable to move. Because of the unfamiliar terrain and flash blindness, the Japanese night fighters had difficulty reaching their assigned objectives. In fact, it was hard for them to reach their jumping-off points. Continuous naval bombardment of crossroads and bridges forced units to rush across in small groups between shells so that the units became strung out on the roads and difficult to control. It was hard to move heavy ammunition and supplies forward because of these interdiction points and the generally churned up roads. Even when units reached their northward assembly points safely by night, they were immediately exposed to aerial observation and artillery fire at dawn, since they lacked enough time to dig in. Units that attacked across American lines safely in darkness had the same problem: they lacked time to dig in and so were utterly exposed to artillery fire at morning light. Night attacks, like flanking maneuvers, were a kind of cure-all in prewar Japanese doctrine. But they failed to provide the expeditious results on Okinawa that IJA doctrine had led the 32d Army Staff to expect. Consequently, Yoshida’s four infiltration attempts, each involving about a squad, were effectively repelled by troops from the 32nd, 184th, and 382nd Regiments before midnight. The only significant attack came from around 45 Japanese soldiers against the positions held by Company G of the 184th, which quickly returned fire, forcing the enemy to retreat to their caves and trenches. In contrast, the assault on the 96th Division on the western front was intense, sustained, and well-coordinated. The forward units of Major-General Nakajima Tokutaro’s 63rd Brigade launched their own local offensive to maintain pressure on the thin line held by the 382nd and 383rd Regiments, while elements from the 23rd, 272nd, and 273rd Independent Battalions infiltrated the American lines and moved into the Ginowan area. The majority of the 272nd Division launched an assault on American positions at Kakazu Ridge, enduring intense naval and artillery fire but ultimately being repelled by the determined defenders after several hours of combat. By morning, the bodies of 317 enemy soldiers were counted on the ridge, whereas the Americans suffered 50 casualties. Meanwhile, the 273rd Division attacked along the west coast against the recently arrived 2nd Battalion of the 106th Regiment, which decisively repelled the Japanese assault and nearly annihilated the independent battalion. Despite this, some units from the 23rd and 272nd Independent Battalions managed to penetrate approximately 1,000 yards behind American lines between Nishibaru and Kaniku but became isolated after dawn on April 13. Throughout the day, Bradley's troops worked to eliminate these infiltrators, many of whom detonated explosives when trapped. When these units retreated into Japanese lines later that night, only half of their original numbers had survived. Just before midnight, the reserve 9th Company of the 22nd Regiment launched an attack against the 184th Regiment following preparatory artillery fire, but this offensive was quickly disrupted by artillery, mortars, and machine-gun fire. On April 14, Nakajima’s forces attempted two more assaults on Kakazu in the early hours, but these attempts were similarly thwarted by artillery and machine-gun fire. Given the failures of the offensives, Ushijima had no choice but to order a suspension of the attack, resulting in a shift to a defensive posture for the Japanese. Over the two days of combat, the 24th Corps reported killing 1,594 Japanese soldiers and capturing four, with losses of fewer than 100 American troops. In the northern region, an extensive air and naval bombardment of Iejima commenced while the Fleet Marine Force Amphibious Reconnaissance Battalion landed on Minna Island, securing it without encountering resistance to position artillery units for General Bruce’s upcoming attack, which would involve the 305th and 306th Regiments. Meanwhile, in northern Okinawa, the 29th Marines continued to advance against enemy positions at Yae-Take through vigorous patrolling, preparing for a morning assault the next day. Concerned about the pace of progress, Shepherd relieved Colonel Bleasdale of command, replacing him with veteran Colonel William Whaling. However, Shepherd recognized that taking the 1,200-foot summit would require more than one regiment, so he ordered the 4th Marines to move from the east coast to Yofuke and then to the southwest corner of the Motobu Peninsula. Additionally, Colonel Shapley’s 3rd Battalion was tasked with moving to Kawada, while the reinforced 2nd Battalion of the 22nd Marines rapidly advanced up the west coast to secure Hedo Misaki. On April 14, Shepherd initiated a coordinated assault on Yae-Take, with Whaling’s 3rd Battalion and Shapley’s 2nd Battalion advancing from the area around Toguchi against unexpectedly light resistance, while the rest of the 29th Marines moved out from Itomi to clear the Itomi-Toguchi Road. Although the eastern front faced strong opposition and required a change in strategy to advance southwesterly for better elevation advantage, rapid progress was made on the west, prompting Shapley to commit his reserve 1st Battalion to secure the exposed right flank. At the same time, Whaling’s 3rd Ba…
