On that day, during Operation Baker near Đức Phổ in the Republic of Vietnam, Stumpf rescued three wounded comrades despite heavy fire and single-handedly disabled an enemy bunker.

Staff Sergeant Stumpf's official Medal of Honor citation reads: For conspicuous gallantry and intrepidity in action at the risk of his life above and beyond the call of duty.

The enemy's heavy volume of fire prevented the unit from moving to the aid of the injured men, but SSG Stumpf left his secure position in a deep trench and ran through the barrage of incoming rounds to reach his wounded comrades.

Arming himself with extra hand grenades, SSG Stumpf ran over open ground, through a volley of fire directed at him by a determined enemy, toward the machinegun position.

SSG Stumpf's relentless spirit of aggressiveness, intrepidity, and ultimate concern for the lives of his men, are in the highest traditions of the military service and reflect great credit upon himself and the U.S.
