Main article: Battle of Guam (1944)

On 21 July 1944, United States Marine and Army forces landed on the west coast of the island of Guam, the southernmost of the Mariana Islands. The island, a U.S. territory prior to World War II, had been captured by forces of the Empire of Japan 8–10 December 1941.

The invasion of Guam was part of Operation Forager, an effort to recapture the entire Marianas chain from Japan. The Guam landings had been tentatively set for 18 June but a large Japanese carrier attack and stubborn resistance by the unexpectedly large Japanese garrison on Saipan led to the invasion of Guam being postponed for a month.

The island was declared secure on 10 August 1944.
