Last time we spoke about the North Borneo Offensive. General Buckner's 10th Army captured strategic locations, including Shuri Castle, marking a turning point. Simultaneously, General Eichelberger's forces liberated Mindanao, overcoming tough Japanese defenses in the mountainous terrain. As they approached Malaybalay, fierce resistance resulted in heavy casualties, but the Americans persisted, inflicting significant losses on their foes. By June 9, the Americans pressed further into the enemy's defensive lines, leading to intense combat. The Marines landed on the Oroku Peninsula, where fierce fighting revealed the tenacity of the Japanese defenders. General Ushijima prepared for a final stand, as American forces began to encircle and dismantle Japanese positions. As the campaign unfolded, Australians under Brigadier Whitehead launched the North Borneo Offensive, landing on Tarakan and swiftly pushing the Japanese into the rugged interior.

Okinawa was more than just a battlefield; it became a symbol of sacrifice, the last heroic stand of a fading empire. By this point in the war, Japan was facing inevitable defeat, yet their resolve remained unbroken. They clung to the samurai spirit, determined to fight to the bitter end out of honor and duty. The stakes were high. Japan needed precious time to fortify its home islands, to stretch the conflict as long as possible. To achieve this, over 100,000 brave souls were sent into the fray, sacrificing their lives to slow the American advance and inflict as many casualties as they could. As we've explored in previous episodes, this fierce determination fueled their resistance. And now, we stand at a pivotal moment, the final days of the Battle of Okinawa, the last major confrontation of the Pacific War.

As we last left the battlefield, it was June 16, General Buckner’s 10th Army had made significant strides, capturing most of southern Okinawa and finally breaking through the last major enemy defenses at the Yaeju Dake-Yuza Dake Escarpment. The remnants of General Ushijima’s 32nd Army were now locked in a desperate fight to hold onto the Kiyamu Peninsula, slowly being pushed back toward the sea and their ultimate demise. The following day, June 17, the assault continued with renewed determination. General Geiger’s 3rd Amphibious Corps pressed on through Kunishi Ridge, while General Hodge’s 24th Corps worked to consolidate its hard-won gains in the escarpment. On the west coast, General Shepherd’s 6th Marine Division took action as Colonel Roberts’ 22nd Marines stepped in to relieve the weary 2nd Battalion, 7th Marines at the northern slope of Mezado Ridge. With a fierce spirit, they began to push southward, successfully securing most of the ridge.

To the east, General Del Valle’s 1st Marine Division forged ahead. Colonel Snedeker’s fresh 3rd Battalion took over from the exhausted 1st Battalion and advanced 1,400 yards to seize the high ground just east of Mezado. Meanwhile, the 2nd Battalion, 5th Marines fought hard to capture the remaining positions of Kunishi Ridge, achieving only a gradual extension to the east. Colonel Griebel’s 3rd Battalion moved in behind them to reinforce the isolated Marines, bravely fending off a fierce counterattack under the cover of night. Further east, Colonel Dill’s 382nd Regiment systematically eliminated the last enemy positions in the Yuza-Ozato-Yuza Dake area, while Colonel Halloran’s 381st Regiment held firm and maintained their lines. In a key maneuver, Colonel Pachler’s 17th Regiment launched a successful assault, capturing Hill 153 before Colonel Green’s 184th Regiment took over during the night. Lastly, Colonel Finn’s 32nd Regiment secured the reverse slopes of Hill 115, preparing to launch an attack on Mabuni and Hill 89. By nightfall, Hodge’s 24th Corps had firmly secured all the commanding heights of the Yaeju Dake-Yuza Dake Escarpment. Most of Mezado Ridge and Kunishi Ridge were now in American hands, and Colonel Wallace’s 8th Marines had landed in the rear to bolster the western push. For the first time, American forces across the line looked down upon nearly eight square miles of enemy-held territory, a staggering view of what lay ahead.

Realizing they were forced from their last defensive positions and that their destruction was imminent, the 32nd Army began to unravel, collapsing into chaos. On June 18, Hodge’s troops seized the opportunity to strike decisively. The 32nd Regiment advanced down the coast toward Mabuni, facing increasing resistance. The 184th Regiment moved down the reverse slopes of Hill 153, closing in on Medeera, while the 381st Regiment speedily crossed the plateau, tackling scattered enemy fire to seize the high ground just 400 yards north of Medeera. Simultaneously, Dill’s 3rd Battalion crashed through a rugged maze of caves and pillboxes, making a daring 600-yard advance to the base of the rocky ridge north of Aragachi. To the west, Griebel’s 1st Battalion circled the eastern end of Kunishi Ridge, battling heavy resistance to gain the lower slopes of Hill 79. Further west, Roberts’ 2nd Battalion pushed through the 3rd and aimed for Kuwanga Ridge, successfully seizing an 1,800-yard stretch by late afternoon. As they advanced, the 3rd Battalion, 4th Marines moved forward to occupy the eastern end of the ridge. Meanwhile, the remainder of the 22nd Marines began to mop up the remnants of resistance on Mezado Ridge. Tragedy struck when Colonel Roberts was tragically killed by a sniper near his observation post during this operation. Lieutenant-Colonel August Larson would succeed him in command. Sadly, Roberts would not be the only American commander to fall that day.

In the heart of the Marine line, the 8th Marines were finally called into action in the morning to relieve the weary 7th Marines. After a rigorous artillery bombardment to soften up the enemy defenses, Wallace’s 2nd Battalion began its advance south toward the Kuwanga-Makabe Road, successfully capturing the high ground just north of the road by late afternoon. Meanwhile, General Buckner decided to visit Wallace’s command post on Mezado Ridge around midday. He observed the 8th Marines’ steady progress in the valley, taking stock of their relentless push forward. Tragically, as he was leaving the observation post, disaster struck. Five artillery shells rained down, one striking a coral outcrop near him. The jagged shards of coral filled the air, and Buckner was mortally wounded in the chest. He died within minutes, just days shy of achieving his goal: the complete capture of Okinawa.

With Buckner's passing, General Geiger, as the senior troop commander, took over temporary command of the 10th Army for the remainder of the battle. Buckner became the highest-ranking American military officer killed in World War II and would hold that somber distinction throughout the entire 20th century. On June 18, the final written order from General Ushijima of the 32nd Army outlined a daring escape plan. He designated an officer to lead the "Blood and Iron Youth Organization," tasked with conducting guerrilla warfare once organized combat had ceased. Simultaneously, he ordered his remaining troops to make their way to the northern mountains of Okinawa, where a small band of guerrillas was rumored to be operating.  In his message he congratulated them on fulfilling their "assigned mission in a manner which leaves nothing to regret." He urged them to "fight to the last and die for the eternal cause of loyalty to the Emperor."

This movement was not to happen in haste. Soldiers were instructed to travel in small groups of two to five over the course of several days. They were urged to don civilian clothes and avoid confrontation whenever possible. In a clever stratagem, most of the army staff officers were directed to leave the command post disguised as native Okinawans, aiming to infiltrate American lines and find safety in northern Okinawa. Some individuals, like Colonel Yahara, were entrusted with the mission of reaching Japan to report to the Imperial General Headquarters. Others were tasked with organizing guerrilla operations, focusing on harassing the rear areas of the 10th Army and Island Command, determined to continue the fight against the American forces in any way they could. Again I have read Yahara’s book on the battle of Okinawa and despite being full of apologetic stuff and attempts to make himself look better, its one of the most insightful books on the Japanese perspective. You get a lot of information on how bad it was for the Okinawan civilians in caves, harrowing stuff. I highly recommend it.

The American attack pressed on into June 19, though it faced delays due to the influx of civilian and military prisoners. Not all of the 32nd Army survivors were imbued with a will "to die for the eternal cause of loyalty to the Emperor." Loudspeakers mounted on tanks in the 7th Division's front lines and on LCI's that cruised up and down the coast line were successful in convincing over 3,000 civilians to surrender. Far more significant, however, were the 106 Japanese soldiers and 2
