The Battle of Okinawa was a great battle of World War II. It took place on Okinawa Island in the Ryukyu Islands (south of the four big islands of Japan). The battle was between the military forces of the Empire of Japan and the Allies. It was the second biggest amphibious battle (from sea to land) of World War II, after the Battle of Normandy. It was also one of the longest battles in history, from April to June 1945. The Allies won the battle and occupied Okinawa. Today, Okinawa is Japanese territory, but there are still American military bases there.
Nobody thought it was to be the last great battle of the war, but it was. The Americans were planning Operation Downfall, the invasion of the four great islands of Japan. This never happened, because the Japanese surrendered after the American use of the atomic bomb in August 1945 (first in Hiroshima, and a second time in Nagasaki) and the Soviet Union declaring war on Japan.
The battle has been called "Typhoon of Steel" in English, and "tetsu no ame," "tetsu no bōfū" by the people of Okinawa, which mean "rain of steel" and "violent wind of steel", because of the very heavy firing of guns and bombs at this battle.
At some battles, such as Battle of Iwo Jima, there had been no civilians, but Okinawa had a large civilian population. The civilians dead or injured in the battle were at least 150,000. American deaths were 18,900 killed or missing and 53,000 injured, more than double of the soldiers killed at Iwo Jima and Guadalcanal put together. Several thousand soldiers who died from wounds and other causes, after the battle had finished, are not included. About a third of the civilian population of the island were killed.
There were about 100,000 Japanese soldiers killed and 7,000 captured. Some of the soldiers committed seppuku or simply blew themselves up with grenades. Some of the civilians, convinced by Japanese propaganda that the Americans were barbarians who did terrible things to prisoners, killed their families and themselves to avoid capture.
Order of battle
Overall Allied command authority for battle was Fifth Fleet (under Admiral Raymond A. Spruance). Fifth Fleet was divided into several task forces and groups.
TF 56 was the largest force within TF 50 and was built around the 10th Army. The army had two corps under its command. In all, the Army had over 102,000 Army (of these 38,000+ were artillery, combat support and HQ troops, with another 9,000 service troops), over 88,000 Marines and 18,000 Navy personnel (mostly Seabees and medical personnel).
At the start of the Battle of Okinawa the 10th Army had 182,821 men under its command. The U.S. Navy had greater casualties in this operation than in any other battle of the war.

Buckner launched another American attack on 11 May. By the end of May, monsoon rains turned hills and roads into mud. .
On 29 May, Maj. Gen. Pedro del Valle ordered Company A, 1st Battalion, 5th Marines to capture Shuri Castle.
The Japanese retreat moved nearly 30,000 men into its last defense line on the Kiyan Peninsula. The 4,000 Japanese sailors — including Admiral Minoru Ota — all committed suicide.
On 18 June, Gen. Buckner was killed by enemy artillery fire. The last Japanese stopped fighting on 21 June, although some Japanese stayed hidden.
