SM UB-27 was a German Type UB II submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. The U-boat was ordered on 30 April 1915 and launched on 10 February 1916. She was commissioned into the German Imperial Navy on 23 February 1916 as SM UB-27.[Note 1] UB-27 sank 13 ships in 17 patrols for a total of 19,437 gross register tons (GRT).[3]
On 29 April 1916 in the North Sea about 15 nautical miles (28 km; 17 mi) south-east of Souter Point near Whitburn, County Durham, UB-27 opened with her deck gun fire at SS Wandle, an 889 GRT "flat-iron" collier of the Wandsworth, Wimbledon and Epsom District Gas Company.[4] The collier engaged the submarine and survived.[4] Afterwards in Britain it was believed Wandle had sunk UB-27 and the master, G.E.A. Mastin, and his crew were celebrated.[5][6]
UB-27 disappeared after 22 July 1917. HMS Halcyon reported ramming and depth charging a U-boat on 29 July 1917. A postwar German study concluded that it was possible that Halcyon sank UB-27 at 52°47′N 2°24′E / 52.783°N 2.400°ECoordinates: 52°47′N 2°24′E / 52.783°N 2.400°E.[2]
