EDWARD C. NONNWEILER, Master Sergeant, Infantry, United States Army. Sergeant Nonnweiler, a member of Company D, 7th Cavalry Regiment, 1st Cavalry Division, displayed extraordinary heroism against the enemy near Ma-dong, Korea on 13 August 1950. In the course of a sneak attack on his unit’s position, Sergeant Nonnweiler spotted the enemy and shouted a warning to his comrades. He immediately moved forward and placed into action a 75mm recoilless rifle on the exposed slopes of the hill in complete view of the enemy, firing the weapon as fast as it could be loaded. With complete disregard for his own safety he deliberately diverted the heavy enemy fire on himself, thus enabling his comrades to place themselves in a more advantageous firing position. The mortar crews were able to divert their fire from another target and place the full force of the mortar fire to their unit’s front. Sergeant Nonnweiler was hit by a burst of machine-gun fire, but despite serious wounds and with his right arm useless, he managed to load and fire the weapon into the charging enemy’s midst, until twice again he was wounded leaving him in such pain that he had to crawl from his position to seek safety where his wounds could be treated. His selfless courage and conspicuous devotion to duty saved his unit from possible annihilation by the overwhelming enemy force. The extraordinary heroism of Sergeant Nonnweiler reflects great credit on himself and is in keeping with the high traditions of the military service.
