SM U 31 was a diesel-electric submarine of the German Imperial Navy that was used in the First World War .
Calls
U 31 was launched on January 7, 1914 at the Germania shipyard in Kiel from the stack and was put into service on September 18 1914th The first and only commander of the submarine was Siegfried Wachendorff .
U 31 only carried out an incomplete patrol on which no sinkings were achieved.
Whereabouts
On January 13, 1915, U 31 ran out to the Hoofden –Smith Knoll operational area off the south-east coast of England. Since then, the boat has been considered lost. All 35 crew members including the commander Oberleutnant zur See Wachendorff died.
In September 2012, the Dutch company Fugro , which was commissioned by ScottishPower and Vattenfall to investigate the seabed with sonar for the construction of a wind farm , located around 55 miles (approx. 89 km) off the coast of Norfolk in 30 m water depth of a wreck that one did not expect there. At first it was suspected that the find was the last missing Dutch submarine “ Mr. Ms. O 13 “from the Second World War . The submarine could be clearly identified on the basis of film recordings made by divers afterwards of the wreck and a metal plaque labeled with SM submarine U-31 , which Dutch navy divers recovered from the bridge of the boat.
According to the underwater archaeologist Mark Dunkley , it can be assumed that U-31 was destroyed by a mine and sank to the sea floor together with the 35-strong crew. The place where the submarine was found is now an official war cemetery , the wind farm planned there is being built elsewhere.
