U-422 operated with the following Wolfpacks during its career:
Leuthen (15 Sep 1943 - 24 Sep 1943)
Attacks on this boat
23 Sep 1943
The boat was depth charged and strafed by an allied aircraft identified as a Halifax. 3 men were wounded, two of them seriously. After requesting medical assistance the boat rendezvoused with milch cow U-460 on the 29th of September. (Sources: Blair, vol 2, page 424)
4 Oct 1943
While being refuelled by U-460 (along with U-264 and U-455) the boats were attacked by Avenger aircraft from the carrier escort USS Card. After putting up heavy flak the smaller VIIC boats dived, leaving U-460 on the surface. She was destroyed when she also tried to dive. U-422 was then attacked later in the day and sunk. (Sources: Blair, vol 2, page 429)
2 recorded attacks on this boat.
Men lost from U-boats
Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-422 did not suffer any casualties (we know of) until the time of her loss.
