In 1917, Britain began running regular convoys to Norway, escorted by light forces; the Germans raided these convoys twice late in the year, prompting Admiral David Beatty, who had replaced Jellicoe the previous year, to send battle squadrons of the Grand Fleet to escort the convoys. The High Seas Fleet went to sea on 23 April to attack one of the escorted convoys, but after the battlecruiser suffered a serious mechanical accident the next day, the Germans were forced to break off the operation. "Revenge" and the rest of the Grand Fleet sortied on 24 April once they intercepted wireless signals from the damaged "Moltke", but the Germans were too far ahead of the British, and no shots were fired.
