Summary of Action
On 9 February 1969, during Operation TAYLOR COMMON, two platoons of Company I were returning from a reconnaissance operation when they were suddenly struck by intense automatic-weapons fire and grenades from a well-concealed North Vietnamese Army force occupying fortified positions. The leading element of the column was isolated, and several Marines were wounded in the opening moments of the ambush.
Lance Corporal William R. Prom, serving as a machinegun squad leader, immediately assumed control of one of his machineguns and began delivering return fire. With complete disregard for his own safety, he advanced forward under fire to a position that allowed him to place more effective covering fire on the enemy while corpsmen administered first aid to the wounded.
Recognizing that evacuation would be impossible unless the enemy was driven off, L/Cpl. Prom again moved forward, pouring a devastating volume of accurate machinegun fire into the enemy positions. His actions were instrumental in routing the North Vietnamese force and allowed the platoon to regroup and continue its movement.
Shortly thereafter, the platoon again came under heavy fire, and another Marine was critically wounded. Reacting instantly, L/Cpl. Prom moved forward once more to shield his injured comrade. Though he was himself severely wounded and no longer able to fire his weapon, he continued advancing to within a few yards of the enemy positions.
Standing fully exposed to hostile fire, L/Cpl. Prom calmly and accurately directed the fire of his supporting elements, ensuring the pressure on the enemy was maintained. While performing this act of extraordinary bravery, he was mortally wounded. Inspired by his fearless leadership and sacrifice, the Marines launched a determined assault that destroyed the enemy force.
Lance Corporal William R. Prom gave his life so that others might live.
