Attacks on U-403 during this patrol

30 Jul 1943
The boat was proceeding on the surface with U-43 when Avenger and Wildcat aircraft from the US escort carrier USS Santee. Both boats dived: two depth charges were dropped on U-403, and a Fido homing torpedo was launched at U-43. U-403 escaped, but U-43 was lost with her crew of 55. (Sources: Blair, vol 2, page 397)

18 Aug 1943
An attack on U-403 on 18 Aug. 1943 in the Atlantic off Dakar in position 14.11N, 17.40W, in which a British Hudson bomber (Sqdn. 200/O) dropped depth charges, was believed to have sunk her, but in fact caused only minor damage.

The boat was sunk later the same day in another attack.
