“With a grenade he led a charge onto the bunker and took out the bunker and saved a number of his platoon,” David Poxon said.

“They landed in a landing zone that was occupied by Viet Cong and first thing the enemy opened up and shot one of Bob’s men. And Bob, being a platoon leader, ran across open ground, tried to secure the position and tried to help the fallen soldier,” he said.

Robert Poxon was mortally wounded in the ensuing firefight.

David Poxon said his father felt guilty for encouraging his son to be a soldier, but he always looked back with pride.

“[He had] the realization that Bob died saving his men, and if he wasn’t there the casualties for his platoon would have been much greater,” he said.

Along with Medal of Honor recipients from the Army, the stamps also honor those from the Navy and Marines.
