SM U 49 was a diesel-electric submarine of the German Imperial Navy , which in the First World War was used.

Calls

U 49 was launched on 26 November 1915 at the Imperial Shipyard in Gdansk from the stack and was put into service on 31 May in 1916. The first and only commander of the submarine was Richard Hartmann .

During the First World War, U 49 carried out six patrols in the eastern North Atlantic . A total of 38 merchant ships from the Entente and neutral states with a total tonnage of 86,433 GRT were sunk.

On its last mission, U 49 was supposed to destroy a submarine cable west of the Dogger Bank. However, it turned out that the cutting device for cutting the cable was defective. Captain Hartmann therefore decided to continue the trade war in the Atlantic. The British steamer Vienna was sunk about 340 miles west of Ouessant ( France ) on September 11, 1917 .

Whereabouts

On the evening of September 11, 1917, U 49 met the armed freighter British Transport in the north-east Atlantic . There was an artillery duel until the German submarine submerged. At nightfall, the British ship sighted the tracks of two torpedoes, which it was able to avoid. The waterway of the submarine was also visible as a phosphorescent strip on the surface of the sea, at the end of which the submarine could be seen like a shadow. According to an instruction to British merchant masters, the British Transport rammed the submarine ahead with extreme force. U 49 lost speed and began to sink over the stern . When the submarine crew wanted to disembark, the British managed a shell hit into the interior of the submarine. U 49 then sank rapidly. All crew members were killed. The sinking occurred about the following west position of Biscay : 46 ° 17 '  N , 14 ° 42'  W .
