Attacks on U-403 during this patrol
30 Jul 1943
The boat was on the surface with the U-43 when Wildcat and Avenger aircraft from the escort carrier HMS Santee attacked the boats. Both dived and U-403 was attacked by two depth charges while the U-43 was attacked by a Fido homing torpedo. U-403 escaped but U-43 did not, being lost with all 55 hands.
