Fitzgerald also served with Utility Squadron Six (VC-6) at NAS Norfolk, Virginia, while working on the Drone Anti-Submarine Helicopter (DASH) program.
Seaman Fitzgerald eventually earned selection for officer training by appointment to the United States Naval Academy at Annapolis, Maryland with the Class of 1963.
This group's compound was located adjacent to the village of Co Luy, near the delta of the Tra Khuc River, and about 70 miles southeast of Da Nang.
In this position, he advised the Republic of Vietnam Navy on defense measures and on the capture of military supplies and contraband destined for Viet Cong forces.
Many calls were made to orbiting gunship aircraft, artillery units, and Fast Patrol Craft to provide defensive fire.
Aware that his bunker was the only remaining source of resistance, Lieutenant Fitzgerald requested an artillery barrage to be laid down on his own position and ordered his men to evacuate the base toward the river.
By his fearless dedication to duty, courage under fire, and heroic actions in defense of the base, despite overwhelming odds, Lieutenant Fitzgerald served as an inspiration to all persons engaged in the counterinsurgency effort in Vietnam and upheld the highest traditions of the United States Naval Service.
