History

SM U-20 was launched in December, 1912. Commissioned the following August, U-20 began patrols with the rest of the fleet after the outbreak of World War I, and was under command of Kapitänleutnant Walther Schwieger from December, 1914. On 7 May, 1915, U-20 and Schweiger sunk the liner RMS Lusitania, sparking outrage from the United States, and forcing the Kaiser to order no further attacks on liners. Nevertheless, Schweiger and U-20 sank the RMS Hesperian, carrying troops, cargo, and functioning as a hospital ship, on 4 September. Schweiger was severely reprimanded, but retained his command, and sank the troop transport SS Cymric on 8 May, 1916. U-20s engines were damaged on 4 November, 1916, and she was run aground off Denmark. The crew detonated her torpedoes, but otherwise failed to destroy U-20, and she remained on the beach until 1925. The Danes blew up the wreck, after removing the conning tower and deck gun, placing the former on display at the Strandingsmuseum.
