The boat was attacked and severely damaged by a British Catalina aircraft (Sqdn 209/Z, pilot Denis E. Ryan) while attempting to cross the Straits of Gibraltar. A Hudson aircraft also appeared and dropped its charges onto the boat. The boat was severely damaged and had to abort to Brest, France. The boat was repaired in a hurry and then sailed for the Mediterranean. (Sources: Blair, vol 1, page 396)

Men lost from U-boats
Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-81 did not suffer any casualties (we know of) until the time of her loss.
