Lieutenant Fitzgerald and three others delayed their retreat as long as possible in order to provide covering fire and to direct fire from surrounding friendly forces. Many calls were made to orbiting gunship aircraft, artillery units, and Fast Patrol Craft to provide defensive fire. The Viet Cong attack, however, was swift and well coordinated. It soon became apparent that the South Vietnamese forces were decimated and that the American bunker was the sole remaining source of resistance. As the situation deteriorated, Fitzgerald ordered his last three remaining defenders to retreat while he used arms fire to cover their escape. Fitzgerald was mortally wounded in this action.
