The 456th had 117 bombers destroyed or written off as salvage during its overseas assignment. Of this number, 91 were lost in combat (20 shot down by fighters, 56 by flak, and 15 by unknown means), with 74 of those crashing in Axis-controlled territory, 10 in the Adriatic Sea, 2 in Switzerland, 3 in Soviet-controlled territory in Poland, one on the island of Vis, and one over Italy. 18 aircraft were destroyed in non-combat related accidents: 4 in flying crashes, 4 on take-offs, 6 on landings, 2 in a mid-air collision over the base, and 2 in accidents while on the ground. 8 battle-damaged aircraft were written off as beyond economical repair. 36 of the original 61 bombers were destroyed and all but one of the rest taken out of service as "war weary".
