His Medal of Honor Citation reads:
On board the U.S.S. TICONDEROGA during attacks on Fort Fisher, 13 to 15 January 1865. As orderly sergeant of Marine guard, and captain of a gun, Orderly Sergeant Fry performed his duties with skill and courage as the TICONDEROGA maintained a well-placed fire upon the batteries to the left of the palisades during the initial phase of the 3-day battle, and thereafter, as she considerably lessened the firing power of guns on the mount which had been turned upon our assaulting columns. During this action the flag was planted on one of the strongest fortifications possessed by the rebels.
