In April 1918, the High Seas Fleet again sortied, to attack British convoys to Norway. They enforced strict wireless silence during the operation, which prevented Room 40 cryptanalysts from warning the new commander of the Grand Fleet, Admiral Beatty. The British only learned of the operation after an accident aboard the battlecruiser forced her to break radio silence to inform the German commander of her condition. Beatty then ordered the Grand Fleet to sea to intercept the Germans, but he was not able to reach the High Seas Fleet before it turned back for Germany. The ship was present at Rosyth, Scotland, when the High Seas Fleet surrendered there on 21 November.
