Goldhammer has it right. "Corpsman up!" is the last thing a Navy hospital corpsman wants to hear. It was those words, after one very loud gunshot, that I heard at the beginning of the battle for Hill 50 in Quang Ngai Province, South Vietnam, in March, 1966. A combined unit of People's Army of North Viet Nam and Main Force Viet Cong soldiers ambushed my company. One of the first shots severely wounded my platoon leader, and I was shot soon after as I was attempting first aid on a wounded Marine.
After the battle, in which 10 Marines in my company were killed, I was evacuated to the hospital ship U.S.S. Repose for emergency surgery. I'm currently building a model of Repose.
