U-665 sent its last radio message on 21 March 1943 announcing its arrival at the rendezvous point off La Pallice in 36 hours. The boat was posted as missing when it failed to meet its escort on 23 March or to report its position.

    Notes. This attack was directed against U-448 inflicting no damage.

Wolfpack operations

U-665 operated with the following Wolfpacks during its career:
   Neuland (4 Mar 1943 - 6 Mar 1943)
   Ostmark (6 Mar 1943 - 11 Mar 1943)
   Stürmer (11 Mar 1943 - 20 Mar 1943)

Men lost from U-boats
