Okinawa · Chapter 1 of 9
The island before the invasion
Okinawa was an inhabited homeland before it became a military objective. Farms, villages, family tombs, sacred places, and the old royal capital at Shuri occupied the ground that operational maps reduced to ridges and numbered hills. The island had been the center of the Ryukyu Kingdom before incorporation into Japan. Its residents cannot simply be folded into the Japanese garrison: many were children, elderly people, or families trying to survive a war they did not direct.
For the Allies, the island offered airfields, anchorages, and room for a great forward base close to Japan. Operation Iceberg was designed to turn those assets against the Japanese homeland. Okinawa also lay on the approaches between Japan, Taiwan, and the East China Sea. Taking it would support air and naval operations and preparations for a possible invasion of Japan.
The attacking Tenth Army joined Army and Marine divisions under Lt. Gen. Simon B. Buckner Jr. Admiral Raymond Spruance commanded the Fifth Fleet, while Vice Adm. Richmond Kelly Turner directed the amphibious forces. Their resources were enormous, but amphibious superiority was not the same as freedom of action once troops moved inland.
Lt. Gen. Mitsuru Ushijima’s 32nd Army concentrated its main defense in the south. Chief of staff Isamu Cho and operations officer Hiromichi Yahara helped shape decisions, sometimes pulling in different directions. Deep shelters, reverse-slope positions, artillery, and mutually supporting strongpoints were intended to make American firepower less decisive. The Japanese aim was attrition: delay the Americans, inflict losses, and keep their supporting ships exposed offshore.
The result was a campaign with several clocks running at once. The fleet had to protect an anchorage under air attack. Infantry had to reduce a fortified landscape. Engineers had to make a base while fighting continued. Civilians had to find food, water, and shelter in the middle of all three. To understand Okinawa, follow those overlapping experiences rather than one uninterrupted arrow moving south.
