Patrol and loss
The boat's only patrol was preceded by a trip from Kiel in Germany to Bergen in Norway. U-422 then left Bergen on 8 September 1943 and headed for the Atlantic Ocean via the gap between Iceland and the Faroe Islands. U-422 was depth charged and strafed by what was reported as a Handley Page Halifax on the 23rd. Three men were wounded, two of them seriously. Medical assistance could only be given when the submarine rendezvoused with U-460, a 'milch cow' supply vessel.
Forty-nine men went down with the U-boat; there were no survivors.
U-422 took part in one wolfpack, namely.
