SM U 83 was a diesel-electric submarine of the German Imperial Navy that was used in the First World War . The submarine was sunk on February 17, 1917, southwest of Ireland by artillery from the British submarine trap Farnborough . Only one crew member survived the bombardment.

Calls

U 83 ran on 13 July 1916, which Germaniawerft in Kiel from the stack and was put into service on September 6, 1916th From the end of October 1916 the boat was assigned to the IV submarine flotilla in Emden and Borkum . The first and only in command was Lieutenant Captain Bruno Hoppe.

U 83 carried out two operations in the North Sea and in the eastern North Atlantic during the First World War . Five merchant ships with a total tonnage of 6,286 gross registered tonnes  (GRT) were sunk. These included ships from warring powers as well as a neutral sailing ship under the Swedish flag.

The largest ship sunk by U 83 was the British freighter Crown Point (5,218 GRT), which was attacked on February 6, 1917 west of the Isles of Scilly . The ship was on a voyage from London to Philadelphia . Seven people were killed in the sinking.

Whereabouts

On February 17, 1917, the crew of U 83 sighted an apparently solo merchant ship southwest of Ireland. In truth, however, it was the British Farnborough submarine trap whose commander, Gordon Campbell , lay in wait for German submarines to be sunk by hidden cannons. However, to be on the safe side, Kapitänleutnant Hoppe went to periscope depth and fired a torpedo at the target while submerged . The torpedo hit the Farnborough in the engine room and part of the crew pretended to flee the ship. Even when lifeboats with supposedly civilian castaways were floating in the water, U 83 remained submerged. It was not until the submarine had circled the heavily damaged Farnborough that Hoppe found it harmless and allowed it to surface about 100 meters away. The British naval flag immediately rose on the Farnborough and artillery fired at U 83 . One of the first shells beheaded Hoppe, who was standing on the submarine bridge. U 83 sank under the bombardment of 45 shells at the position of 51 ° 34 '  N , 11 ° 23'  W . After the sinking, eight survivors initially swam in the water, but only two could be saved. One of them died soon after from serious injuries.

The damaged Farnborough could be kept afloat until she reached Berehaven on the Irish south-west coast and was set aground there. The commander and crew received high awards for sinking U 83 .

Others

Like its sister boats, the U 83 demonstrated a high level of seaworthiness. The series became the model for the submarine class IX and foreign designs.

The commander of U 83 , Bruno Hoppe, as the commander of U 22, had mistakenly sunk U 7 , the first German submarine to be lost through self-fire .
