Battle of Okinawa

[33][34] The nicknames refer to the ferocity of the fighting, the intensity of Japanese kamikaze attacks and the sheer numbers of Allied ships and armored vehicles that assaulted the island.

After the battle, Okinawa provided the victorious Allies with a fleet anchorage, troop staging areas, and airfields in close proximity to Japan as they planned to invade the Japanese home islands.

[19]: 97 The protracted length of the campaign under stressful conditions forced Admiral Chester W. Nimitz to take the unprecedented step of relieving the principal naval commanders to rest and recuperate.

[44] Operation Ten-Go (Ten-gō sakusen) was the attempted attack by a strike force of ten Japanese surface vessels, led by Yamato and commanded by Admiral Seiichi Itō.

Several kamikaze attacks caused significant damage, but as the Royal Navy carriers had armored flight decks, they experienced only a brief interruption to their force's operations.

[19]: 50–60 On 31 March, Marines of the Amphibious Reconnaissance Battalion landed without opposition on Keise Shima, four islets just 8 mi (13 km) west of the Okinawan capital of Naha.

The 2nd Marine Division conducted a demonstration off the Minatoga beaches on the southeastern coast to deceive the Japanese about American intentions and delay movement of reserves from there.

The terrain was mountainous and wooded, with the Japanese defenses concentrated on Mount Yaedake, a twisted mass of rocky ridges and ravines on the center of the peninsula.

[19]: 105–108 The next American objective was Kakazu Ridge (26°15′32″N 127°44′13″E / 26.259°N 127.737°E / 26.259; 127.737)(see ja:嘉数の戦い), two hills with a connecting saddle that formed part of Shuri's outer defenses.

The effort led the 32nd Army's staff to conclude that the Americans were vulnerable to night infiltration tactics but that their superior firepower made any offensive Japanese troop concentrations extremely dangerous, and they reverted to their defensive strategy.

Battleships, cruisers, and destroyers joined the bombardment, which was followed by 650 Navy and Marine planes attacking the Japanese positions with napalm, rockets, bombs, and machine guns.

The losses might have been greater except for the fact that the Japanese had practically all of their infantry reserves tied up farther south, held there by another feint off the Minatoga beaches by the 2nd Marine Division that coincided with the attack.

The ground advance began to resemble a World War I battlefield, as troops became mired in mud, and flooded roads greatly inhibited evacuation of wounded to the rear.

The 32nd Army was able to move nearly 30,000 personnel into its last defense line on the Kiyan Peninsula, which ultimately led to the greatest slaughter on Okinawa in the latter stages of the battle, including the deaths of thousands of civilians.

In addition, there were 9,000 IJN troops supported by 1,100 militia, with approximately 4,000 holed up at the underground headquarters on the hillside overlooking the Okinawa Naval Base in the Oroku Peninsula, east of the airfield.

On 19 June, Brigadier General Claudius Miller Easley, the commander of the 96th Infantry Division, was killed by Japanese machine-gun fire, also while checking on the progress of his troops at the front.

[19]: 468–471  Colonel Yahara had asked Ushijima for permission to commit suicide, but the general refused his request, saying: "If you die there will be no one left who knows the truth about the battle of Okinawa.

Four days from the closing of the campaign, Buckner was killed by Japanese artillery fire, which blew lethal slivers of coral into his body, while inspecting his troops at the front line.

[23] The Allies destroyed 27 Japanese tanks and 743 artillery pieces (including mortars, anti-tank and anti-aircraft guns), some of them eliminated by the naval and air bombardments but most knocked out by American counter-battery fire.

[90] The museum writes that "some were blown apart by [artillery] shells, some finding themselves in a hopeless situation were driven to suicide, some died of starvation, some succumbed to malaria, while others fell victim to the retreating Japanese troops.

In March 2007, the national Ministry of Education, Culture, Sports, Science and Technology (MEXT) advised textbook publishers to reword descriptions that the embattled Imperial Japanese Army forced civilians to kill themselves in the war to avoid being taken prisoner.

"[102][103] On 29 September 2007, about 110,000 people held the biggest political rally in the history of Okinawa to demand that MEXT retract its order to textbook publishers regarding revising the account of the civilian suicides.

The resolution states, "It is an undeniable fact that the 'multiple suicides' would not have occurred without the involvement of the Japanese military and any deletion of or revision to (the descriptions) is a denial and distortion of the many testimonies by those people who survived the incidents.

[105] The ministry's Textbook Authorization Council allowed the publishers to reinstate the reference that civilians "were forced into mass suicides by the Japanese military", on condition it is placed in sufficient context.

[114] At least 90% of the buildings on the island were destroyed, along with countless historical documents, artifacts, and cultural treasures, and the tropical landscape was turned into "a vast field of mud, lead, decay and maggots".

The US cleared the surrounding waters of mines in Operation Zebra, occupied Okinawa, and set up the United States Civil Administration of the Ryukyu Islands, a form of military government, after the battle.

Because Japan surrendered when it did, the anticipated series of battles and the invasion of the Japanese homeland never occurred, and all military strategies on both sides which presupposed this apparently-inevitable next development were immediately rendered moot.

Some military historians believe that the Okinawa campaign led directly to the atomic bombings of Hiroshima and Nagasaki, as a means of avoiding the planned ground invasion of the Japanese mainland.

This view is explained by Victor Davis Hanson in his book Ripples of Battle: ... because the Japanese on Okinawa ... were so fierce in their defense (even when cut off and without supplies), and because casualties were so appalling, many American strategists looked for an alternative means to subdue mainland Japan, other than a direct invasion.
