On 15 September 1944, United States Marine Corps forces landed on the southwestern shore of the island of Peleliu in the Palau island chain, 470 nautical miles due east of the Philippine island of Mindanao. This action, called Operation Stalemate II by American planners, was a phase in the Pacific Theatre of World War II. Whether possession of the island was necessary for the Allied cause has been the source of much controversy.

Peleliu was the least-known island that the US invaded in the Pacific Theatre. Pre-war maps were sorely lacking and the results of photoreconnaissance were poor. Thus, the Marines were completely unprepared for the hard, sharp surface of blistering hot bare coral over much of the landing area.

Defeating the entrenched Japanese forces turned out to be far more arduous than anticipated. Two regiments of Army troops were unexpectedly needed to finish conquest of the island. Peleliu was finally declared secure on 15 November 1944.

US Command Structure

Naval

The roles of Commander in Chief, Pacific Ocean Areas (CINCPOA) and Commander in Chief, U.S. Pacific Fleet (CINCPAC), were both exercised by Admiral Chester W. Nimitz from his headquarters at Pearl Harbor, Hawaii.

Since the Palaus lie in the Southwest Pacific, their capture was the responsibility of the U.S. Third Fleet, led by Admiral William F. Halsey from aboard his flagship, fast battleship New Jersey.

The ships and embarked troops of Operation Stalemate II, were under the overall command of Rear Admiral Theodore S. Wilkinson aboard amphibious command ship Mount Olympus.

Ground Troops

Marine Corps planning for Stalemate II was conducted by Major General Julian C. Smith. However, because the III Amphibious Corps was still struggling with the capture of Guam, operational command for the Palaus was turned over to Major General Roy S. Geiger.
