Attacking with aerial depth charges and one Mark 24 FIDO acoustic homing torpedo, U-422 was sunk immediately while the other three submarines submerged. As more aircraft and escort ships arrived in the area, a hunt for the other submarines ensued resulting in U-460 being sunk by aerial depth charges about seven miles away. U-264 and U-455 got away but U-264 was damaged. ww2dbase [F4F Wildcat | TBF Avenger | U-460 | Card | Mark XXIV | DS]
