The Second Battle of Guam (July 21 â€” August 8, 1944) was the American capture of the Japanese held island of Guam (in the Mariana Islands) during the Pacific campaign of World War II. A few Japanese soldiers held out in the jungle. On December 8, 1945, three U.S. Marines were ambushed and killed. On January 24, 1972, Sergeant Shoichi Yokoi was discovered by hunters. He had lived alone in a cave for 27 years. After the battle, Guam was turned into a base for Allied operations. Five large airfields were built by the Seabees, and B-29 bombers flew from the island to attack targets in the Western Pacific and on mainland Japan. Four U.S. Marines were awarded the Medal of Honor for their heroic actions during the Battle of Guam: PFC Luther Skaggs Jr., PFC Frank Witek (posthumously), PFC Leonard F. Mason (posthumously) and Captain (later General) Louis H. Wilson, Jr.. Liberation Day continues to be celebrated on Guam every July 21.
