The scuttling of the German fleet took place at the Royal Navy's base at Scapa Flow in Scotland after the end of the First World War. The High Seas Fleet had been interned there under the terms of the Armistice whilst negotiations took place over the fate of the ships. Fearing that the fleet would be seized and divided amongst the allied powers, the German commander, Admiral Ludwig von Reuter, decided to scuttle the fleet.
The scuttling was carried out on 21 June 1919. Intervening British guard ships were able to beach a number of the ships, but 52 of the 74 interned vessels sank. Many of the wrecks were salvaged over the next few years and were towed away for scrapping. The few that remain are popular dive sites.
The signing of the Armistice on 11 November 1918, at Compiègne, France, ended the First World War. The Allied powers had agreed that Germany's U-boat fleet should be surrendered without the possibility of return, but were unable to agree upon a course of action regarding the German surface fleet. Admiral Rosslyn Wemyss suggested that the fleet be interned at Scapa Flow with a skeleton crew of German sailors, and guarded in the interim by the Grand Fleet.
