先島諸島
During World War II, there was an air battle waged against the Sakishima Islands' two largest islands that lasted for 82 days in order to neutralize Kamikaze airfields. Twenty-five US escort carriers, five larger fast carriers with their air groups consisting of fighters and torpedo bombers along with heavy naval patrol bombers and an assortment of DD-Destroyers and DE-Destroyer Escorts along with the British Pacific Fleet bombed, rocketed and fired their guns at runways and other targets daily while the land battle raged on Okinawa 175 miles away. This was the least publicized battle for its size that took place involving the Americans and British during the war. The thirty-two thousand seasoned Imperial Japanese Army (IJA) and Naval (IJN) troops on Miyako did not surrender until 27 days after Japan formally surrendered. The amount of ordnance expended against the Sakishima Islands may have exceeded the ordnance spent on the island of Iwo Jima. The Sakishima Islands did not suffer a ground invasion during World War II, although a great deal of anti-submarine warfare and convoy battles took place in the waters immediately surrounding the archipelago in the years leading up to the Okinawa campaign. A number of American and Japanese submarines were lost on the approaches to these islands as they formed a vital outlying defense to the Empire's shipping bottlenecks in the Formosa (Taiwan) and Luzon Straits.
