- 176 - Pacific War Podcast - the Invasion of Okinawa - April 1 - 8 - , 1945

Last time we spoke about the Visayas Offensive. In March 1945, the Pacific War raged on. On Iwo Jima, the US Marines, after intense fighting and heavy casualties, declared the island secured. Meanwhile, in northern Luzon, General Clarkson's division advanced towards Baguio, facing fierce Japanese resistance, while General Mullins pushed through Balete Pass. The Japanese army, grappling with severe supply shortages, was forced to evacuate Baguio. In the Visayas, General Eichelberger's forces targeted the Sulu Archipelago and Central Visayan Islands, securing key airfields. The 40th Division landed on Panay, capturing Iloilo, and launched an assault on northern Negros. On Cebu, the Americal Division landed near Talisay, encountering mines but minimal resistance, and secured Cebu City. By April, Allied forces had made strategic advances across the Philippines, overcoming Japanese resistance and establishing crucial airfields.

We have come to the grand final battlefield at last, that of Okinawa. Of course battles are raging in all sorts of other theaters like New Guinea, China, Burma, etc. However as you might imagine its becoming impossible given the week by week format to cover all of this in single episodes. So we are going to hardcore focus on Okinawa for awhile, we will circle back to the other theaters to catch up. Seriously it was the only logical way to do this and honestly in retrospect I wish the entire podcast was campaign by campaign instead of week by week. But I am a mere podcaster following the youtube series of this. But if you want to hear a campaign by campaign series, over at Echoes of War me and my cohost Gaurav are beginning to roll them out. The first series will be the entire Malayan Campaign, and I think after that I might try to do the Philippines. Regardless lets jump into the invasion of Okinawa.

As previously noted, the directive issued by the Joint Chiefs of Staff on October 3 designated Okinawa as the final target for invasion, following the establishment of air and naval bases in Luzon and Iwo Jima. Capturing this crucial island would bring the conflict to Japan's doorstep, disrupt the enemy's air communications through the Ryukyu Islands, and flank their maritime routes to the south. Consequently, from these newly established air and naval bases in the Ryukyus, American forces would be able to launch attacks on Japan's main islands and implement a more rigorous sea and air blockade, isolating them from Japanese territories to the south. This made it imperative for the Japanese Empire to maintain control over Okinawa and the Ryukyus. To this end, the 32nd Army, led by Lieutenant-General Watanabe Masao, was formed there by late March 1944. Initially, it comprised four companies and one artillery regiment stationed at Amami Oshima; five companies and one artillery regiment at Nakagusuku Bay; four companies and one artillery regiment at Iriomote Island; along with various garrison units from the 19th Air District in Okinawa. 

Under Operation Tei-Go, the Ryukyus and Formosa were to form a long zone of interprotective air bases. These bases were expected to defeat any American sea or air forces sent into the region. To avoid destruction from the air, each base was to consist of a cluster of airfields, such that if one were damaged others could be used immediately. Military and civilian crews were promptly set to work building the numerous fields. 13 base clusters had to be created, stretching in a line from Tachiarai in the northern Ryukyus to Pingting on Formosa in the south. The only remaining tasks for ground forces were the defense of these facilities and their support anchorages and the unenviable work of building the fields. Much of the energy of 32nd Army would be absorbed building these air facilities. This was more difficult since 32nd Army had only two bulldozers and one earth roller. Japan had produced dozers in small numbers at its Komatsu plant since 1943, but few had reached the front. Since soldiers were thus obliged to use shovels, hoes, straw baskets, and horse-drawn wagons, construction was slow. Moreover, because of enemy sub
