German heavy cruiser Lützow, light cruiser Emden, light cruiser Leipzig, and destroyers passed through the Skagerrak between Denmark and Norway. Despite aerial cover by Bf 110 fighters, a British force of Beaufort torpedo bombers with fighter escort was still able to get through and attack, damaging Lützow with a torpedo hit in the engine room. Lützow was forced to return to Kiel, Germany for repairs.
