Construction edit

SM UB-85 was built by AG Weser of Bremen and following just under a year of construction, launched at Bremen on 26 October 1917, and was commissioned later that same year. Like all Type UB III submarines, UB-85 carried 10 torpedoes and was armed with a 8.8 cm (3.46 in) deck gun. UB-85 would carry a crew of up to 3 officers and 31 men and had a cruising range of 8,180 nautical miles (15,150 km; 9,410 mi). UB-85 had a displacement of 516 t (508 long tons) while surfaced and 647 t (637 long tons) when submerged. Her engines enabled her to travel at 13.4 knots (24.8 km/h; 15.4 mph) when surfaced and 7.5 knots (13.9 km/h; 8.6 mph) when submerged.

Service history edit

On her second patrol, she was picked up by HM Drifter Coreopsis II [Note 2] off the coast of Belfast, Ireland on 30 April 1918, after she was partially flooded through a semi-open hatch while trying to evade attack by the British vessel.[3] The ingress of water could not be controlled, since cables for a heater in the officers' compartment had previously been laid through a watertight door, by order of Kapt. Krech.[5] The submarine was forced to surface and was abandoned by her crew while under fire. No casualties occurred amongst the 34 crew and they were taken as prisoners of war.[6]

Relationship with cryptozoology edit

Under interrogation, the captain is reported to have said that the submarine had surfaced the night before to recharge the batteries and had been attacked by a large sea creature that had damaged the vessel and left it unable to submerge. The crew had fired their sidearms at the creature.[7][8]

Wreck edit

Engineers working on an electricity cable, the Western HVDC Link, discovered the almost intact wreck of a UB-III class submarine, believed to be either UB-85 or UB-82, lying off the Galloway coast in October 2016.[9] Dr Innes McCartney who identified the wreck said: "We are certainly closer to solving the so-called mystery of UB-85 and the reason behind its sinking - whether common mechanical failure or something that is less easily explained."[7]
