SM U-106

SM U-106 was one of the 329 submarines serving in the Imperial German Navy in World War I. U-106 was commissioned on 28 Jul 1917, under the command of Kapitänleutnant Hans Hufnagel, and participated in one wartime patrol starting on 2 September 1917. On 18 September 1917, during the First Battle of the Atlantic, U-106 was credited with the sinking of HMS Contest, an Acasta class destroyer, and damaging "City of Lincoln", a 5,867 ton steamer, in the Western Approaches. She was lost off Terschelling after striking a mine on 7 October 1917.

In 2009 the Royal Netherlands Navy found the wreckage of the ship north of Terschelling, while charting sea-routes. The news was made public in March 2011, after the ship's identity had been confirmed by German authorities and the crewmembers' families had been informed. The ship will stay in place as a wargrave.
