 Following the armistice with Germany in November 1918 , the majority of the High Seas Fleet was to be interned in the British naval base in Scapa Flow . Bayern was listed as one of the ships to be handed over , though Baden initially was not . The battlecruiser Mackensen , which the British believed to be completed , was requested instead . When it became apparent to the Allies that Mackensen was still under construction , Baden was ordered to replace it . On 21 November 1918 , the ships to be interned , under the command of Rear Admiral Ludwig von Reuter , sailed from their base in Germany for the last time . The fleet rendezvoused with the light cruiser HMS Cardiff , before meeting a massive flotilla of some 370 British , American , and French warships for the voyage to Scapa Flow . Baden arrived at Scapa Flow separately on 14 December 1918 .
