The Battle of Tinian was a battle of the Pacific campaign of World War II, fought on the island of Tinian in the Mariana Islands from 24 July until 1 August 1944. The 9,000-man Japanese garrison was eliminated, and the island joined Saipan and Guam as a base for the Twentieth Air Force.
A two-prong attack through the Central Pacific and the Philippines was adopted at the 1943 Cairo Conference. Operation Granite II, was a U.S. Navy devised strategy of island hopping, calling for the seizure of Saipan, Tinian and Guam. The Gilbert and Marshall Islands had been seized by the summer of 1944, while some Japanese garrisons were left to starve.
The Japanese defending the island, the 50th Infantry Regiment, which was originally part of 29th division, were commanded by Colonel Kiyochi Ogata and his subordinate Goichi Oya. Vice-Admiral Kakuji Kakuta, commander of First Air Fleet, was headquartered in Manila, but on Tinian on an inspection tour when the invasion started.
