 In August 1942 , she conducted Operation Wunderland , a sortie into the Kara Sea to interdict Soviet shipping and attack targets of opportunity . The length of the mission and the distances involved precluded a destroyer escort for the operation ; three destroyers would escort Admiral Scheer until they reached Novaya Zemlya , at which point they would return to Norway . Two U @-@ boats — U @-@ 251 and U @-@ 456 — patrolled the Kara Gate and the Jugor Strait . The Germans originally intended to send Admiral Scheer with her sister ship Lützow , but since the latter had run aground the previous month , she was unavailable for the operation .
