Drowley USA, squad leader in a platoon whose mission during an attack is to remain under cover, hold the perimeter and act as a reserve for the assault company, sees three members of the assault company fall badly wounded. Drowley rushes forward to carry the wounded to cover. After rescuing two men, Sergeant Drowley discovers an undetected enemy pillbox that is inflicting heavy casualties upon the attacking force and is the main obstacle to the success of the advance. He delegates the rescue of the third man to an assistant and runs across open terrain to one of the assaulting tanks. Signaling to the crew, he climbs to the turret, exchanges his weapon for a submachine gun and rides the deck of the tank directing it toward the pillbox with tracer fire. The tank continues to within 20 feet of the pillbox where Drowley receives a severe bullet wound in the chest. He remains on the tank and continues to direct its progress until the enemy box is located by the crew. He remains alongside the tank until the pillbox is destroyed. Sergeant Drowley is awarded the Medal of Honor. |
