 Dunham again advanced ahead of his platoon in an assault on enemy positions farther up the hill.Coming under machinegun fire from 65 yards to his front, while rifle grenades exploded 10 yards from his position, he hit the ground and crawled forward.At 15 yards range, he jumped to his feet, staggered a few paces toward the timbered machinegun emplacement and killed the crew with hand grenades.
