Soon after graduating high school, Harvey "Barney" Barnum, Jr. joined the Marine Corp Platoon Leaders Course, where he learned various military infantry tactics. Once Barnum earned his degree, he was given an officer's commission in the Marine Corps Reserves and sent to the gritty jungles of Vietnam in 1965.
On December 18, Barnum and the rest of the Marines were patrolling in the Quảng Tín Province of South Vietnam. Unbeknownst to Barnum and his men, as the Marines moved deep into the enemy territory, they were walking into a vicious trap. The Vietnamese troops had dug themselves into the nearby terrain and waiting as nearly three companies of Marines walked by, headed toward a small village.
Then, a firefight broke out, first striking the Marine's rear position and moving to the front of the patrol as the grunts entered the enemy-infested village. What happened next, no first-timer would ever expect.
The initial attack severely injured the company commander and the radio operator. This deadly wave was Barnum's first taste of real combat — and his training kicked in immediately. He went and retrieved the radio, calling for heavy fire support.
Barnum also dashed out of his position to recover the company commander and move him to safety. Moments later, Barnum's commanding officer died in his arms. With all the men looking for guidance, the young Marine knew it was up to him to assume control and direct a counterattack.
After passing out orders, the Marines laid a curtain of gunfire onto the trench line from which the enemy had so much success earlier. Barnum picked up a rocket launcher and fired it three times at the enemy position. That was the signal the attack Hueys needed.

After running out of rockets, the Marine officer directed the Hueys above towards targets to nail — and that's just what they did. This airborne attack freed up some terrain, allowing the wounded and the dead to be transported out. Although still surrounded by enemy troops, Barnum choreographed each squad as they moved from the hot zone.
In roughly 45 minutes, the men found safety.
