In this March 27, 1973 photo, an American GI takes a nap atop his luggage as he and other troops wait to begin out processing at Camp Alpha in Saigon, as withdrawal of U.S. troops resume after a 10-day dispute over POWs. All U.S. troops are due out Thursday. As the last U.S. combat troops left Vietnam 40 years ago, angry protesters still awaited them at home. North Vietnamese soldiers took heart from their foes' departure, and South Vietnamese who had helped the Americans feared for the future. While the fall of Saigon two years later — with its indelible images of frantic helicopter evacuations — is remembered as the final day of the Vietnam War, Friday marks an anniversary that holds greater meaning for many who fought, protested or otherwise lived it.
