Background

Unternehmen Wunderland (Operation Wonderland) was a coordinated raid of the pocket battleship Admiral Scheer and U-boats in the Kara Sea occurred in 1942, resulting in a limited German success. A follow-up similar operation code-named Unternehmen Wunderland II was planned for 1 August 1943 with involvement of the Lützow but her participation was cancelled. Despite the official end of Wunderland II for 4 October 1943, operations in Kara Sea resumed the following year until 4 October 1944.[1]

Unternehmen Wunderland II

Since August 1943 U-255 operated near Novaya Zemlya as a refuelling station for a BV 138. The BV 138 searched for Kara Sea convoys to be attacked by Lützow and the Wiking Gruppe.[2]
