Combat Action
Led "Flanker Right" — 4 Nov 1965 action near Position Cavalair
As D Company XO, Trapnell was alerted by the company commander, Capt. Samuel Linton, to take the "Flanker Right" element — 2nd Platoon of A Company, a medic, an interpreter, and others — forward to the camp and LZ to organize the elements already engaged, sweep and secure the area, and evacuate casualties. The element came under heavy sniper and B-40 fire on the hill. Trapnell directed the evacuation of the wounded and dead and the destruction of the enemy camp before the action closed that evening. He later recalled the fight in his 2008 eulogy for Recon Platoon Sergeant Clint Marshall.
