Battle of Guam 

On July 21, 1944, US troops landed on Guam, initiating a three-week battle to recapture the island. The largest of the Mariana Islands, Guam had been a United States possession since its capture from Spain in 1898.  However, following the attack on Pearl Harbor, Japanese forces took the island on December 10, 1941.
