- 189 - Pacific War Podcast - The Invasion of Balikpapan - July 1 - 8, 1945

Last time we spoke about liberation of Luzon.. American forces, led by General Eichelberger and supported by General Krueger's armies, relentlessly advanced against the entrenched Japanese defenders of General Yamashita’s 14th Area Army. Amid thick jungle and treacherous terrain, battles raged through the northern mountain ranges, as American troops aimed to restore the Filipino government. Facing overwhelming odds, the Japanese forces displayed extraordinary resilience, temporarily halting American progress. Remarkable efforts from General Swift’s 1st Corps across Routes 9 and 11 led to significant breakthroughs as American forces captured critical positions, including Sablan and Baguio. However, the Japanese command, complacent and misjudging the American strategy, fell into disarray. As the tide turned with relentless American assaults, key Japanese positions were systematically dismantled. By late April, most of Luzon was liberated, restoring hope and autonomy to the Filipino people.

The battles for Okinawa and Luzon just closed up, and today we are going to be venturing back to the Dutch East Indies. As we left off in mid-May, the tides of war were shifting dramatically on the island of Luzon, with General Krueger's 6th Army celebrating significant victories across the region. In the north, General Swift’s 1st Corps had successfully secured the scenic Baguio area, known for its lush mountains and cool climate, a stark contrast to the tropical heat that engulfed much of the Philippines. Yet, the fighting was far from over, as fierce battles continued on three major fronts. Colonel Volckmann’s guerrilla 121st Regiment was making strides, snagging much of the strategically vital Bessang Pass, a crucial artery connecting northern Luzon to the central regions. However, their success came at a cost, leaving them overextended amidst fierce Japanese resistance. Meanwhile, General Gill’s weary 32nd Division managed to claim dominance over the rugged terrain of Salacsac Pass along the historic Villa Verde Trail, known for its breathtaking views and treacherous paths that had challenged both soldiers and their supply lines.

General Mullins’ 25th Division achieved a remarkable breakthrough by capturing the key Balete Pass, opening the way for further advances. Not stopping there, the 25th Division pressed onward, quickly redirecting their focus northward towards the town of Santa Fe. By May 24, the 27th Regiment had cleared the Sawmill River valley, an area teeming with dense foliage and rugged hills, a significant accomplishment that paved the way for the next objectives. From there, the 1st Battalion expertly maneuvered eastward against the imposing Kanami Ridge. On May 22, the 161st Regiment dealt a heavy blow to Japanese positions in a stronghold on Mount Haruna, a location known for its steep, challenging slopes. Following this triumph, they began their descent down the northern slopes of Haruna Ridge, gearing up for a critical junction with the Villa Verde Trail by May 27. Meanwhile, the 35th Regiment launched a vigorous assault from Balete Pass, systematically clearing out the remaining Japanese caves and fortifications by May 26, culminating in the capture of Santa Fe the very next day. At Salacsac, the Japanese forces, led by General Iwanaka, initiated a limited counteroffensive, presumably to buy time for a strategic evacuation of their increasingly tenuous positions. If delay was indeed Iwanaka's intention, he executed it well; it wasn’t until May 19 that the American supply line was finally deemed secure again. The 2nd Battalion of the 128th Regiment resumed its push east from Hill 525, but the progress was slow. By May 22, the 1st Battalion had only managed to advance a mere 500 yards east from Hill 508, while the 3rd Battalion commenced a southward and southeastward advance from Hill 516 on May 16. It was not until May 24 that the relentless fighting in the region bore fruit, leading to the eventual clearing of the area, and Salacsac Pass was officially declared secured.

On that pivotal day, General Iwanaka began the difficult task of withdrawing the remnants
