“Expendable Warriors’ is an autobiographical account of the battle of Khe Sanh by one of the genuine American heroes of the 1968 Tet Offensive. That alone makes the work both a primary historical source and interesting reading material…[B]eyond history and autobiography, Col. Clarke offers two significant criticisms of the way the Vietnam War was fought: the lack of unity of command, and the misguided attempt to measure victory by body count. Professional and amateur historians will appreciate this text, and so will teachers of political and military science, as well as teachers of international relations.”
