From today's featured articleSMS Oldenburg was the fourth Helgoland-class battleship of the Imperial German Navy. Built between 1909 and 1912 at the Schichau-Werke shipyard in Danzig, Oldenburg was assigned to I Battle Squadron of the High Seas Fleet for most of her career, including World War I. Oldenburg participated in all of the major fleet operations during the conflict against the British Grand Fleet, including the Battle of Jutland on 31 May and 1 June 1916, the largest naval battle of the war. The ship also saw action in the Baltic Sea against the Imperial Russian Navy. After the German collapse in November 1918, most of the High Seas Fleet was interned and then scuttled in Scapa Flow during the peace negotiations. The four Helgoland-class ships remained in Germany but were ceded to the Allied powers as war reparations; Oldenburg was given to Japan, which sold the vessel to a British ship-breaking firm in 1920. She was scrapped in Dordrecht in 1921. (This article is part of a featured topic: Battleships of Germany.)
