Last time we spoke about the breakthrough on Okinawa. Despite relentless attacks on critical positions like Sugar Loaf Hill and Wana Ridge, American Marines encountered heavy casualties. Yet, they persisted, inching forward against tenacious resistance. As mid-May approached, the situation for Japanese commanders deteriorated. Encircled and suffering significant losses, they began plotting a retreat to more defensible positions. On the ground, Marines battled through mud and enemy fire, showcasing incredible resolve amidst dire circumstances. Communication crumbled, supplies dwindled, and morale waned, yet the determination of both sides was undeniable. By late May, the tides shifted further in favor of the Allies, marking pivotal breakthroughs despite the challenges. Amidst ruin and chaos, the relentless struggle for control over Okinawa symbolized the brutal nature of war and the unwavering spirit of those fighting on both sides, setting the stage for an eventual Allied victory.

As we last left off, the battle for Okinawa was reaching a critical juncture. General Buckner’s 10th Army had made significant gains, successfully breaking through the fortified Japanese defenses on both flanks. The 6th Marine Division, under General Shepherd, had effectively established control over the Naha area, while General Arnold’s 7th Division achieved an impressive penetration at Yonabaru. However, despite these advancements, the remainder of the American forces faced formidable obstacles. They were grappling with relentless rain, fierce enemy resistance, and severe supply shortages, which left them effectively stalled in front of Shuri. In response to the encroaching American forces, General Ushijima had dispatched General Fujioka’s 62nd Division to launch a counter-offensive aimed at driving the invaders out of Yonabaru. Meanwhile, Ushijima was preparing his 32nd Army for a strategic withdrawal south to the Kiyamu Peninsula. Fortunately for the Americans, they had caught wind of the defenders' intentions. Recognizing the urgency of the situation, on May 27, General Buckner ordered his troops to apply strong and unrelenting pressure on the enemy. The goal was clear: keep the Japanese forces off balance and prevent an easy transition to new defensive positions. Although the continuing downpour hindered the possibility of a large-scale, coordinated army-wide attack, it did not deter Buckner’s strategy. Instead, he initiated a series of strong combat patrols along the front lines, which immediately encountered stiff resistance from Japanese troops that had not yet begun their withdrawal. On the west coast, as patrols from Colonel Roberts’ 22nd Marines scouted the area, they discovered that the Japanese had largely abandoned Naha. This news spurred the 2nd Battalion into action. They crossed the Asato River, moved through the lines established by Shepherd’s Reconnaissance Company, and pressed deeper into the western part of Naha. Simultaneously, Colonel Shapley’s 4th Marines made their last desperate push to extend American control into eastern Naha, fighting valiantly against the entrenched enemy. Farther east, Colonel Finn’s 32nd Regiment once again faced fierce resistance from the hastily committed 62nd Division, which staunchly defended its position. However, not all was lost; patrols from Colonel Green’s 184th Regiment managed to reach Inasomi, meeting only scattered resistance. This breakthrough provided a crucial indication that the enemy had no intention of withdrawing into the Chinen Peninsula.

As the clocks struck midnight, a significant yet largely unnoticed transition occurred in the waters off Okinawa: Admiral Halsey’s 3rd Fleet relieved Admiral Spruance’s 5th Fleet. For the troops ashore, this change in command went by without a hint of recognition. The same ships and task groups continued their crucial support for ground operations, now operating under new numerical designations and leadership. However, Halsey faced an immediate challenge as Admiral Ugaki launched an extensive Kikisui attack, a large-scale kamikaze assault involving 110 enemy aircraft. The day of May 27 proved costly, with three destroyers, one destroyer minesweeper, two transports, one subchaser, and two auxiliary ships all suffering damage. The following morning brought clear skies, which only heightened the danger for American naval forces. Several kamikaze aircraft succeeded in sinking the destroyer USS Drexler, while also inflicting damage on a transport ship, three freighters, and a landing craft throughout the day. Meanwhile, on land, Colonel Whaling’s rehabilitated 29th Marines took over from the battered 4th Marines along the west coast. The 1st Battalion executed a concerted attack alongside the 22nd Marines, advancing successfully by 250 yards through the rubble-strewn city of Naha. In an impressive display of momentum, Roberts’ men pushed forward unopposed toward the Kokuba estuary, eventually encountering resistance near Ono-Yama Island. To the east, the improvement in weather allowed Colonel Mason’s 1st Marines to launch a coordinated offensive. The 2nd Battalion fought valiantly, climbing to the peak of 110 Meter Hill. The forward elements of Company E gained the hill crest but were forced to withdraw by vicious enemy fire which raked their positions. Lieutenant Colonel Magee felt that his depleted battalion, down to a total strength of 277 men in the rifle companies, might recapture the hill, but "it could not possibly hold it against a strong enemy counterattack." Although new replacements were available to regiments for training or other use, a division order prevented their being sent to front line units during a battle situation that called for the utmost in skill and knowledge of veterans. Throughout most of the morning and all of the afternoon, 2/1 concentrated the fire of its supporting weapons on the reverse slopes of 110 Meter Hill and engaged the Japanese in a fierce and continuous fire fight. Nightfall brought no cessation of enemy resistance, and many infiltrators were killed in the battalion's lines. In contrast, the 3rd Battalion experienced relatively little opposition, allowing some patrols to penetrate into Wana Draw. At the same time, Colonel Griebel’s 3rd Battalion effectively moved its front line to the Asato River, while his 1st Battalion achieved a significant milestone by capturing Beehive Hill. However, despite the break in the rain, the conditions on the ground rendered large-scale movements impractical, stalling further advances across the battlefield.

Despite Arnold’s determined efforts to push west through Fujioka’s blocking positions, progress was minimal. Nevertheless, he was able to consolidate his grip on the Ozato hill mass as Green’s 2nd Battalion advanced to a position within 1,000 yards of Shinazato, strategically located at the neck of the Chinen Peninsula. The lack of success from the 62nd Division in driving back the breaching American forces reinforced General Ushijima’s resolve to evacuate Shuri while the opportunity still existed. In light of this, he ordered the withdrawal to commence the following evening. On May 29, while the 7th Reconnaissance Troop managed to scout a significant portion of the Chinen Peninsula without incident, the 7th and 96th Divisions faced fierce resistance as they attacked toward the road network south of Shuri. The enemy’s resolute defense resulted in only minimal gains for the American assault units. General Bruce's 77th Division, after what can be described as "a day almost entirely spent in hand-to-hand combat," found itself unable to penetrate the intense cordon of defensive fire that protected the Japanese positions. In stark contrast, to the west, Griebel’s 1st Battalion made a rapid advance, quickly gaining the crest of Shuri Ridge. They launched a bold assault on Shuri Castle.

On May 25, as part of the final stages of the Okinawa campaign, the American battleship USS Mississippi bombarded the castle for three days, and by May 27, it was engulfed in flames. That night, the Japanese forces retreated, abandoning Shuri while US troops pursued them southward. The 1st Battalion of the 5th Marines had started its attack on 29 May with Companies B and C in assault and Company A following in trace of Company C. The Marines quickly gained the crest of Shuri Ridge and Lieutenant Colonel Shelburne requested permission for one of his companies to storm Shuri Castle which commanded his position. Although the castle was in the zone of action of the 77th Infantry Division, General del Valle gave his assent to the request in view of the great danger of enemy action from the strong point. The 1st Marine Division commander felt that "at that time the position of the 77th Division was such that it would have taken several hard day's fighting through enemy resistance" before the castle could be taken. Company A drove east along the muddy ridge line, overwhelming the few Japanese in its path, and by 1015 the castle, core of the Shuri bastion, had been secured. The Marine unit entered Shuri through a gap in the covering forces caused
