Marine 1st Lt. Harvey “Barney” Barnum jumped to the ground when he came under fire during an ambush in Vietnam that killed his radio operator and commander.
Collecting himself, Barnum realized he was now the highest-ranking officer of a rifle company he'd just joined. He called in artillery and, amid gunfire, dragged the commander to safety, where he died in Barnum’s arms. Then he proceeded to mount a counterattack, oversee evacuation of the wounded and lead the unit’s eventual break out to rejoin the battalion.
