The American invasion of the island of Okinawa , codenamed Operation Iceberg, took place 1 April 1945. The Japanese military was determined to inflict a casualty rate so high that the U.S. government would choose not to invade the Japanese home islands. To this end, the southern portion of the island had been covered with the most extensive system of fortifications and fields of fire yet encountered in the Pacific War.
The island was not declared secure until 22 June, a period of 82 days. Lieutenant General Simon Bolivar Buckner Jr. became the highest ranking U.S. military officer to be killed in action in the Second World War.
