Kapitänleutnant Richard Hartmann commanded U-49 throughout her career until she was sunk on 11 September 1917 in action in the Bay of Biscay. While surfaced, U-49 attacked the merchant ship British Transport, which had sailed Brest, France bound for Archangel in Russia, laden with munitions and other explosives. After a gun battle lasting five hours, U-49 fired two torpedoes at British Transport. Both missed, and the merchantman then rammed and sank her at 46°17′N 14°42′W; all hands were lost.[2]

It was the first time in the war that a merchant ship had sunk a U-boat. In February 1918 British Transport's Master, Captain AT Pope, was made a Companion of the Distinguished Service Order,[3][4][5] three of her officers were awarded the DSC,[6] seven of her crewmen were awarded the DSM and three were mentioned in dispatches.[7]
