The Battle of Angaur was a battle of the Pacific campaign in World War II, fought on the island of Angaur in the Palau Islands from 17 September 1944 to 30 September 1944.
Angaur is a tiny volcanic island, just 3 miles (4.8 km) long, separated from Peleliu by a 6-mile (9.7 km) strait. A very small indigenous population lived by farming, fishing, and phosphate mining. In mid-1944 the Japanese had 1,400 troops on the island, under the overall command of Palau Sector Group commander, Lieutenant General Sadae Inoue.
The weak defenses of the Palaus and the potential for airfield construction made them attractive targets for the Americans after the capture of the Marshall Islands, but shortage of landing craft meant that operations against the Palaus could not begin until the Mariana Islands were secure.
