U-52's second notable warship kill was the French battleship Suffren, sunk 90 miles (140 km) west of Portugal at 39°30′N11°00′W / 39.500°N 11.000°W / 39.500; -11.000.[11] on 26 November 1916. All 648 men were lost as the torpedo ignited a magazine and the ship sank within seconds.[12]
U-52 was surrendered to the Allies at Harwich on 21 November 1918 in accordance with the requirements of the Armistice with Germany. She was sold by the British Admiralty to George Cohen on 3 March 1919 for £2,400 (£139,300 in 2024) (excluding her engines), and was broken up at Swansea.[13]
One of the ordinary seamen on board U-52 was Julius Schopka (1896–1965). After the war he emigrated to Iceland and became an Icelandic citizen. In 1928, together with Icelandic journalist Árni Óla he published his memoirs from the war years, in Icelandic, Kafbátahernaðurinn (The Submarine Warfare). That book was in turn used by Icelandic author Illugi Jökulsson when he published the book Úr undirdjúpunum til Íslands — Julius Schopka, U-52 og heimsstyrjöldin fyrri (From the Depths to Iceland — Julius Schopka, U-52 and the First World War) in 2019. Illugi also used the unpublished memoirs of Hans Walther, who was captain of the U-52 for most of her operational time.[14]
