Vietnam -- Stumph picked up 1 of the men and carried him back to the safety of the trench. Twice more S/Sgt. Stumpf dashed forward while the enemy turned automatic weapons and machineguns upon him, yet he managed to rescue the remaining 2 wounded squad members. He then organized his squad and led an assault against several enemy bunkers from which continuously heavy fire was being received He and his squad successfully eliminated 2 of the bunker positions, but one to the front of the advancing platoon remained a serious threat. Arming himself with extra hand grenades, S/Sgt. Stumpf ran over open ground, through a volley of fire directed at him by a determined enemy, toward the machinegun position. As he reached the bunker, he threw a hand grenade through the aperture. It was immediately returned by the occupants, forcing S/Sgt. Stumpf to take cover. Undaunted, he pulled the pins on 2 more grenades, held them for a few seconds after activation, then hurled them into the position, this time successfully destroying the emplacement. With the elimination of this key position, his unit was able to assault and overrun the enemy.
