Battle of Peleliu

The Battle of Peleliu, codenamed Operation Stalemate II by the US military, was fought between the United States and Japan during the Mariana and Palau Islands campaign of World War II, from 15 September to 27 November 1944, on the island of Peleliu. US marines of the 1st Marine Division and then soldiers of the US Army's 81st Infantry Division fought to capture an airfield on the small coral island of Peleliu. The battle was part of a larger offensive campaign known as Operation Forager, which ran from June to November 1944 in the Pacific War. Major General William Rupertus, the commander of the 1st Marine Division, predicted that the island would be secured within four days.
