Guam, a U.S. territory, gets invaded by Japan a few days after Pearl Harbor and remains under occupation for two and a half years before the Americans arrive to take Saipan and Guam back, and finished off as well the Japanese fleet in a classic turkey shoot. The Guamanians are thankful as expressed on their smiling faces, making it one of the most inspiring segments of Victory at Sea. Meanwhile, the Americans are preparing the bases in the islands as well as in other areas of the Marianas for the ultimate bomber offensive against Japan.
