Guam: The Radioman
In 1941, the Japanese forces took control of the U.S. territory in Guam and most of the U.S. citizens escaped. Six soldiers, however, were left behind. Two-and-a-half years later, only one had successfully managed to escape capture: George Tweed, the Radioman. The reason for his success included good hiding spots and his intimate knowledge of electronics — but the biggest source of support came from the people of Guam who risked their lives to keep him safe.
