Korean War Medal of Honor Recipient. He was awarded the Medal of Honor for his heroic actions of November 2, 1950. His citation reads "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, First Battalion, Seventh Marines, First Marine Division (Reinforced), in action against enemy aggressor forces in the vicinity of Sudong, Korea, on 2 November 1950. 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, Staff Sergeant 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 forty yards of fierce enemy fire to reunite his troops despite an elbow wound which rendered one 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 loss of blood, Staff Sergeant 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 United States Naval Service." He received his Medal of Honor from President Harry S. Truman on February 6, 1952. His remains were cremated and scattered at sea.
