While leading a patrol he attacked an enemy formation of 12 planes (Fokker type). He engaged one enemy and sent it down out of control. One of his guns jammed and while he was repairing the gun two of the enemy planes got behind him. Unable to repair the gun and only to fire a single shot, he turned to attack, destroying a second plane, and remained in the fight until the enemy retired.
