At dawn, Friday, August 30, 1968, I woke inside my cockroach-infested hooch at LZ Betty, sixteen miles south of the Demilitarized Zone, to go on my twenty-second and last patrol. I was the sergeant and team leader of a five-man long-range reconnaissance patrol assigned to the First Cavalry Division’s First Brigade, whose area of operation was from Quang Tri City, near the coast of South Vietnam, to the heavily forested mountains out west, halfway to Laos.
