A groundbreaking revisionist history of the last days of the Vietnam War that reveals the acts of American heroism that saved more than one hundred thousand South Vietnamese from communist revenge. In 1973 U.S. participation in the Vietnam War ended in a cease-fire and a withdrawal that included promises by President Nixon to assist the South in the event of invasion by the North. But in early 1975, when North Vietnamese forces began a full-scale assault, Congress refused to send arms or aid. By early April that year, the South was on the brink of a defeat that threatened execution or years in a concentration camp for the untold number of South Vietnamese who had supported the government in Saigon or worked with Americans.
