He was an aid man with the 1st Platoon of Company C during an attack on the town of Alemert, Germany. The platoon, committed in a flanking maneuver, had advanced down a small, open valley overlooked by wooded slopes hiding enemy machineguns and tanks, when the attack was stopped by murderous fire that inflicted heavy casualties in the American ranks. Ordered to withdraw, Cpl. Kelly reached safety with uninjured remnants of the unit, but, on realizing the extent of casualties suffered by the platoon, voluntarily retraced his steps and began evacuating his comrades under direct machinegun fire. He was forced to crawl, dragging the injured behind him for most of the 300 yards separating the exposed area from a place of comparative safety. Two other volunteers who attempted to negotiate the hazardous route with him were mortally wounded, but he kept on with his herculean task after dressing their wounds and carrying them to friendly hands. In all, he made 10 separate trips through the brutal fire, each time bringing out a man from the death trap. Seven more casualties who were able to crawl by themselves he guided and encouraged in escaping from the hail of fire. After he had completed his heroic, self-imposed task and was near collapse from fatigue, he refused to leave his platoon until the attack had been resumed and the objective taken. Cpl. Kelly's gallantry and intrepidity in the face of seemingly certain death saved the lives of many of his fellow soldiers and was an example of bravery under fire.
