U-266 operated with the following Wolfpacks during its career:
Jaguar (10 Jan 1943 - 27 Jan 1943)
Pfeil (4 Feb 1943 - 9 Feb 1943)
Amsel (22 Apr 1943 - 3 May 1943)

Men lost from U-boats
Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-266 did not suffer any casualties (we know of) until the time of her loss.
