Summary of Action
During Operation ROCK, a 15-man Marine reconnaissance patrol occupied an observation post on Hill 146 overlooking the Quan Duc Valley deep inside enemy-controlled territory.
In the early morning hours, the patrol was suddenly attacked by a platoon-sized North Vietnamese force using automatic weapons, satchel charges, and grenades.
Amid the chaos of the assault, a grenade landed inside the three-man fighting hole occupied by Private First Class Ralph H. Johnson and two fellow Marines.
There was no time to throw it back.
Without hesitation, Johnson shouted a warning.
Then he threw himself directly onto the grenade.
When the explosion erupted, he absorbed the full force of the blast and was killed instantly.
His selfless act saved the life of one Marine and prevented the enemy from penetrating that critical section of the patrol’s perimeter.
Private First Class Ralph H. Johnson’s extraordinary courage and sacrifice stand as a lasting example of devotion to his fellow Marines and reflect the highest traditions of the United States Marine Corps and the Naval Service.
