In the summer of 1966, in the middle of the Vietnam War, eighty young volunteers arrived at the Marine Corps Recruit Depot on Parris Island, South Carolina, from all over the eastern United States. For the next eight weeks, as Platoon 1005, they endured one of the most intense basic training programs ever devised. Parris Island was not a place for idle conversation or social gatherings, and these men remained from start to finish almost complete strangers. W. D. Ehrhart did get to know one Marine, his bunkmate John Harris, who quietly shared his sweetheart's letters. He was a friend who, Ehrhart learned almost thirty years later, died in Vietnam in 1967. In 1993, Ehrhart began what became a five-year search for the men of his platoon. Who were these men alongside whom he trained? Why had they joined the Marines at a time when being sent to war was almost a certainty? What do they think of the war and of the country that sent them to fight it? What does the Corps mean to them? What Ehrhart learned offers an extraordinary window into the complexities of the Vietnam Generation and the United States of America then and now.
