SM U-124 was one of the 329 submarines serving in the Imperial German Navy in World War I. U-124 was engaged in the naval warfare and took part in the First Battle of the Atlantic under the command of Kapitänleutnant Rolf Carls (later a Generaladmiral in the Kriegsmarine).
She was interned at Karlskrona on 13 November 1918, but then surrendered to the Allies at Harwich on 1 December 1918 in accordance with the requirements of the Armistice with Germany. Lying at Portland, she was sold to James Dredging Co. on 3 March 1919 for £3,000, but then re-sold to George Cohen, who towed the boat to Swansea for scrapping. However, U-124 foundered there in October 1920, although was later salvaged and finally broken up.
