After making a last-ditch stand against the Japanese on Mindanao, Fort received orders to surrender from his higher command. However, despite surrendering Fort let the Maranaos claim the U.S. Army's rifles and equipment, which they would then use in
guerrilla warfare. Fort was then escorted by the
Kempeitai to Manila, where he remained for several months. In November 1942 the Japanese sought Fort's help in talking to the Moro people, who had started a new rebellion against the occupying forces. Specifically, Fort was supposed to tell the Moro that since the U.S. Army had surrendered they must also surrender. An Allied
war crimes tribunal later sentenced Tanaka to death by hanging for the executions of Fort and three other Americans, and he was executed at
Sugamo Prison on April 9, 1949. After Fort's execution Moro
guerrilla groups staged revenge attacks against Japanese forces. named Ignacio S. Cruz said he located Fort's remains and turned them over to the
American Graves Registration Service. and six other families of missing soldiers filed a lawsuit against the U.S. government's
Defense POW/MIA Accounting Agency. The families are seeking an order to exhume the bodies of Fort and others and do DNA tests to identify the remains. ==Military awards==
