On July 21, 1944, Guam was assaulted by the US Marine from the 3rd Amphibious Corps. The Japanese managed to contain the attackers on the two landing beach and counterattacked, but failed to repulse the landing. Afterwards, the Marines renewed their assault, and reached the northern tip of Guam by August 10, 1944.

After Guam was secured, the island was developed into a major base area with several airfields to support B-29 Superfortress operations against the Japan.
