Guam had been a US territorial possession from 1899 until December 8, 1941, when it was invaded by the Japanese. It was the largest as well as most southern island in the Marianas chain.

Amphibious Landings

The US assault to recapture Guam was planned for July 21, 1944, against a well prepared Japanese army. Two separate landings took place by the III Amphibious Corps; one above and one below the Orote Peninsula, both on the west side of the island.

Beaches Red, Green & Blue1

 • The assault over Beaches Red, Green and Blue utilized 193 LVT(2)s and LVT(4)s of the 3rd Amphibian Tractor Battalion, and "A" company of the 11th Amtrac Battalion, transporting three infantry regiments of the 3rd Mar Div.

 • The 1st Armored Amphibian Tractor Battalion (less "A" and “B” Companies) lead the assault with 36 LVT (A)1s, equipped with a 35mm cannon.
