The Wikipedia article of the day for January 13, 2018 is SMS Wittelsbach.
SMS Wittelsbach (His Majesty’s Ship Wittelsbach) was the lead ship of her class of pre-dreadnought battleships, built for the German Imperial Navy. She was the first capital ship built under the Navy Law of 1898, which was brought about by Admiral Alfred von Tirpitz. Wittelsbach was laid down in 1899 at the Wilhelmshaven Navy Dockyard and completed in October 1902, armed with a main battery of four 24 cm (9.4 in) guns and with a top speed of 18 knots (33 km/h; 21 mph). During World War I the ship served in the IV Battle Squadron, with limited non-combat duty in the Baltic Sea, including during the Battle of the Gulf of Riga in August 1915. By late 1915, crew shortages and the threat from British submarines forced the navy to withdraw older battleships like Wittelsbach. The ship then saw service in auxiliary roles, first as a training ship and then as a ship’s tender. In 1919, after the war, she was converted to a tender for minesweepers.
