SM U-52 was one of 329 submarines serving in the Imperial German Navy in World War I. U-52 was engaged in the naval warfare and took part in the First Battle of the Atlantic.

[8] The sinking of Nottingham was an important event in the German Imperial Navy's action of August 19.

[10] U-52's second notable warship kill was the French battleship Suffren, sunk 90 miles (140 km) west of Portugal at 39°30′N 11°00′W / 39.500°N 11.000°W / 39.500; -11.000.

She was sold by the British Admiralty to George Cohen on 3 March 1919 for £2,400 (£139,300 in 2025) (excluding her engines), and was broken up at Swansea.

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.
