For conspicuous gallantry and intrepidity in action at the risk of his life above and beyond the call of duty. Pfc. Nash distinguished himself while serving as a grenadier with Company B, in Giao Duc District. When an ambush patrol of which he was a member suddenly came under intense attack before reaching its destination, he was the first to return the enemy fire. Taking an exposed location, Pfc. Nash suppressed the hostile fusillade with a rapid series of rounds from his grenade launcher, enabling artillery fire to be adjusted on the enemy. After the foe had been routed, his small element continued to the ambush site where he established a position with 3 fellow soldiers on a narrow dike. Shortly past midnight, while Pfc. Nash and a comrade kept watch and the 2 other men took their turn sleeping, an enemy grenade wounded 2 soldiers in the adjacent position. Seconds later, Pfc. Nash saw another grenade land only a few feet from his own position. Although he could have escaped harm by rolling down the other side of the dike, he shouted a warning to his comrades and leaped upon the lethal explosive. Absorbing the blast with his body, he saved the lives of the 3 men in the area at the sacrifice of his life. By his gallantry at the cost of his life are in the highest traditions of the military service, Pfc. Nash has reflected great credit on himself, his unit, and the U.S. Army.
