The Battle of Okinawa was the largest amphibious assault in the Pacific War of World War II. On June 21, 1945, after 82 days of battle, the Japanese troops were defeated. This was not intended to be the final major battle of World War II, only the staging ground for the Allied invasion of Japan. The ferocity of the fighting on Okinawa, combined with the massive number of casualties, forced American strategists to seek alternative means for ending the war, as the destruction on Okinawa would surely have paled in comparison to any invasion of the Japanese home islands. The following article, originally published in the January 1946 issue of Proceedings, gives a personal account of the assault on Okinawa.
By Captain E. E. Paro, U.S. Navy
The High councils of war had reached a decision. They were in agreement and a directive was issued for a proposed amphibious operation in the Pacific.
There were many assumptions in the directive and the operation was to accomplish certain very desirable military objectives which later unfolded themselves but which are not discussed herein.
The target selected was Okinawa Shima in the Ryukyus. Information on this island was sketchy to say the least but its geographical location was very clear and definite. It is located 325 miles from the Japanese home island of Kyushu, 400 miles from Shanghai and about the same distance from Formosa. The directive stated that fanatical and determined air opposition by the entire Japanese air force could be expected. It was known that the Japanese had in existence certain paratroop units which would probably be employed, enemy surface naval opposition was a threat, and enemy troop reinforcements could be expected from any of the localities mentioned above. The target was heavily garrisoned and completely ringed by prepared enemy defense positions of great strength and in depth. It had a native population of 440,000 all of which must be assumed to be hostile. The terrain was exceedingly adaptable to defense, particularly in the northern and extreme southern positions of the island. The beaches were few and these were fringed by rough coral heads, and the depth of the water over them was unknown. The weather could be expected to be stormy for at least 20 per cent of the time and the island lay in the center of the path of most of the typhoons, which were frequent and severe.
