SM U-86
SM U-86
was a Type U 81 style submarine manufactured in the Germaniawerft, Kiel
Kiel
shipyard for the German Empire
German Empire
during World War I.[1] On 27 June 1918, under the command of Lieutenant Helmut Patzig, U-86 sank the Canadian hospital ship HMHS  Llandovery Castle
Llandovery Castle
off the coast of Ireland, in violation of international law and standing orders of the Imperial German Navy. When the crew took to the lifeboats, U-86 surfaced, ran down all the lifeboats except one, and shot at the people in the water. Only the 24 people in the remaining lifeboat survived. They were rescued shortly afterwards and testified as to what had happened. The 234 others on board Llandovery Castle were lost, including fourteen nursing sisters.[6] USS Covington,[7] the former Hamburg America ocean liner SS Cincinnati, was torpedoed by U-86 on 1 July 1918 and sank the next day.[8] Covington was the 17th largest ship sunk or damaged by U-boats during the war.[1]

A 1918 Canadian propaganda poster used U-86's sinking of Llandovery Castle as a focal point for selling Victory Bonds.

After the war, the captain of U-86 Helmut Patzig, and two of his lieutenants were arraigned for trial on war crimes, but Patzig fled to the Free City of Danzig, and his trial was stopped on 20 March 1931 by virtue of the Laws of Amnesty. Lieutenants Ludwig Dithmar and Johan Boldt were convicted and sentenced to four years in prison, but were released after only 4 months. U-86 was surrendered after the war and sank in the English Channel

Design[edit] German Type U 81 submarines were preceded by the shorter Type UE I submarines. U-86 had a displacement of 808 tonnes (795 long tons) when at the surface and 946 tonnes (931 long tons) while submerged.[2] She had a total length of 70.06 m (229 ft 10 in), a pressure hull length of 55.55 m (182 ft 3 in), a beam of 6.30 m (20 ft 8 in), a height of 8 m (26 ft 3 in), and a draught of 4.02 m (13 ft 2 in). The submarine was powered by two 2,400 metric horsepower (1,800 kW; 2,400 shp) engines for use while surfaced, and two 1,200 metric horsepower (880 kW; 1,200 shp) engines for use while submerged. She had two propeller shafts. She was capable of operating at depths of up to 50 metres (160 ft).[2] The submarine had a maximum surface speed of 16.8 knots (31.1 km/h; 19.3 mph) and a maximum submerged speed of 9.1 knots (16.9 km/h; 10.5 mph).[2] When submerged, she could operate for 56 nautical miles (104 km; 64 mi) at 5 knots (9.3 km/h; 5.8 mph); when surfaced, she could travel 11,220 nautical miles (20,780 km; 12,910 mi) at 8 knots (15 km/h; 9.2 mph). U-86 was fitted with six 50 centimetres (20 in) torpedo tubes (four at the bow and two at the stern), twelve to sixteen torpedoes, and one 10.5 cm (4.1 in) SK L/45 deck gun (from 1917). She had a complement of thirty-five (thirty-one crew members and four officers).[2] Summary of raiding history[edit]
