For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty while serving as a platoon sergeant in Company B, in action against enemy aggressor forces. Immediately rallying the men in his area after a fanatical and numerically superior enemy force penetrated the center of the line under cover of darkness and pinned down the platoon with a devastating barrage of deadly automatic weapons and grenade fire, S/Sgt. Van Winkle boldly spearheaded a determined attack through withering fire against hostile frontal positions and, though he and all the others who charged with him were wounded, succeeded in enabling his platoon to gain the fire superiority and the opportunity to reorganize. Realizing that the left flank squad was isolated from the rest of the unit, he rushed through 40 yards of fierce enemy fire to reunite his troops despite an elbow wound which rendered 1 of his arms totally useless. Severely wounded a second time when a direct hit in the chest from a hostile hand grenade caused serious and painful wounds, he staunchly refused evacuation and continued to shout orders and words of encouragement to his depleted and battered platoon. Finally carried from his position unconscious from shock and from loss of blood, S/Sgt. Van Winkle served to inspire all who observed him to heroic efforts in successfully repulsing the enemy attack. His superb leadership, valiant fighting spirit, and unfaltering devotion to duty in the face of heavy odds reflect the highest credit upon himself and the U.S. Naval Service.
