- 146 - Pacific War Podcast - Invasion of Morotai 2 - September 9 - , 1944

Last time we spoke about the end of Operation Dan. In Yunnan, by late July, General Wei's Y Force worked to eliminate Japanese garrisons at Tengchong, Mount Song, Pingda, and Longling. The 33rd Army prepared for Operation Dan, anticipating resistance from General Honda's garrisons until September. The fall of Myitkyina prompted Honda to expedite his plans. Reinforcements were expected in Mandalay by September. General Matsuyama's forces, cut off and surrounded, provided support only through radio messages. At Tengchong, Colonel Kurashige vowed to defend against relentless attacks. Chinese forces, after intense fighting and bombing raids, breached the city's defenses. Despite heavy casualties, the Japanese resisted fiercely. Major Kanemitsu’s garrison defended Moung Song with dwindling supplies. The Chinese forces employed siege tactics and underground mines to break Japanese strongholds. The Chinese launched coordinated attacks, capturing key positions and ultimately compelling Japanese retreats.  This episode is the Invasion of Morotai Welcome to the Pacific War Podcast Week by Week, I am your dutiful host Craig Watson.

The Japanese had stationed the 14th Division at Palau and the 32nd Division at Halmahera as their primary defenses. The Halmahera-Morotai area had not assumed much importance to the Japanese until early 1944, when they began to develop Halmahera as a focal point for the defense of the southern approaches to the Philippines. In addition to the 32d Division, the Japanese had on Halmahera innumerable service organizations, and they completed or had under construction nine airfields on the island, most of them in northern Halmahera. On that island they concentrated nearly 30,000 men, including at least 11,000 combat troops.  On Halmahera, General Ishii commanded approximately 11,000 troops to safeguard nine airfields, despite having already lost most of their air power. Meanwhile, Morotai Island was defended by around 500 Formosans of the 2nd Raiding Unit, led by Major Kawashima Takenobu. General Ishii planned to counterattack from Halmahera if the Allies landed on Morotai, but soon realized Allied air and naval superiority would foil these efforts. Following their defeat in the Marianas, Tokyo reassigned the Bonin Area Group directly under its command and placed the Palau Area Group under the Southern Army, leaving General Mugikura’s 31st Army to defend Truk and other isolated outposts. General Inoue fortified Palau with elaborate defenses along the coast and inland, manned by 21,000 Imperial Japanese Army (IJA) troops, 7,000 Imperial Japanese Navy (IJN) personnel, and 10,000 laborers.  The IJN had by 1944 constructed numerous reinforced concrete blockhouses and bunkers plus dug an extensive tunnel system near the end of the northeast peninsula as well as taking full advantage of Peleliu's natural caves. This elaborate, multi-level tunnel system could shelter 1000 troops. These defenses, tunnels, the airfield, and the many support facilities were built by the 204th, 214th, and 235th Construction Battalions, mostly manned by Koreans and Okinaw
