history

The order for the boat was awarded to the Germania shipyard in Kiel on August 23, 1914 . The keel was laid on December 19, 1914, the launch on November 25, 1915, the commissioning under Lieutenant Walter Rumpel finally took place on February 24, 1916.

After its commissioning on February 24, 1916, the boat belonged to the 1st Flotilla until May 25, 1916. From May 25, 1916 until its sinking, the boat belonged to the 2nd Flotilla.

During its service, U 51 undertook a patrol without sinking the ship.

First patrol

When leaving the mouth of the Ems, U 51 was on July 14, 1916 at position 53 ° 56 '  N , 7 ° 55'  E. Coordinates: 53 ° 56 '0 "  N , 7 ° 55' 0"  E of the British submarine HMS H5 (Lt. H. "Crom" Varley) sunk. Varley had not received an assignment from the British Admiralty for this area of ​​the sea. Out of "boredom" he had left the operating area assigned to him and had run into more promising waters. Of two torpedoes shot down , one hit U 51 below the tower. Despite being in enemy waters, Varley showed up to take German survivors to England as evidence of the sinking. The H 5 was however taken under fire by two German torpedo boats and forced to dive. After several hours of pursuit, H 5 escaped.

In U 51 , 18 survivors and the commander crowded into the bow space . Since there weren't enough diving rescuers , they waited for slow death by suffocation . After four hours they tried to get out, but only two of the men in the bow reached the surface of the water. Three other men were released from the stern compartment, one of whom died when surfacing.

Memorial in Bremen

The boat was lifted in November 1968. 21 dead were recovered and buried in the Osterholz cemetery in Bremen . A memorial there commemorates the accident and the crew members who died.
