On 21 November 1918, following the Armistice, the entire Grand Fleet left port to escort the surrendered German fleet into internment at Scapa Flow. At the time, "Revenge" was part of the 1st Battle Squadron, commanded by Vice-Admiral Sydney Fremantle, who made "Revenge" his flagship. The 1st BS was tasked with guarding the fleet while its fate was being determined at the peace treaty negotiations at the Versailles conference. After the Germans scuttled their fleet on 21 June 1919, Fremantle had the German commander, Rear Admiral Ludwig von Reuter, brought aboard "Revenge". Fremantle accused Reuter of violating the terms of the armistice and had him and the German officers taken into captivity as prisoners of war.
