SM U-83 was a Type U 81 u-boat of the German Imperial Navy (Template:Lang-de) during the First World War. She had been commissioned and deployed to operate off the coast of the British Isles and attack coastal shipping as part of the German U-boat campaign.[1]
In a six-month career, U-83 made two combat patrols into the South-Western Approaches during the Atlantic campaign. In these patrols she sank five allied merchant ships for 6,286 gross register tons (GRT). On 17 February 1917, she torpedoed the British Q-ship HMS Farnborough off the Irish coast, but was sunk by Farnborough's hidden armaments when she approached too close. There were just 2 survivors, picked up by Farnborough; 35 of her crew perished. Farnborough was commanded by the submarine hunter Gordon Campbell and had on board later Victoria Cross recipients Ronald Niel Stuart and William Williams.
