Tinian was not garrisoned by the Japanese military until the latter stages of World War II, when the Japanese realized its strategic importance as a possible base for American Boeing B-29 Superfortress bombers. The island was seized by the Allies during the Battle of Tinian from 24 July to 1 August 1944. Of the 8,500-man Japanese garrison, 313 survived the battle. At the time, there were an estimated 15,700 Japanese civilians (including 2700 ethnic Koreans) on the island. Many hundreds were also killed in the crossfire, took their own lives, or were executed by the Japanese military to avoid capture by the Americans.Prefer, Nathan N.
