Lorient Submarine Base

Lorient Submarine Base was a submarine naval base located in Lorient, France. It was built in 1941 by the German Kriegsmarine, and was continued to be enlarged until 1943. After the German defeat it was used by the French Navy. It was decommissioned in 1995 and converted to civilian use.After the fall of France in June 1940 the head of Germany’s U-boat Arm, Konteradmiral Karl Dönitz, was keen to use the French Atlantic ports as forward bases for his U-boat force then engaged in a commerce war against the United Kingdom. Prior to this U-boats had to travel from ports in Germany to their patrol areas, losing valuable time in the long transits necessary. From the coast of France these distances were substantially reduced, with a corresponding increase in the active range and endurance of the U-boat force. Dönitz lost no time in sending teams of engineers and base personnel to the ports, beginning with Lorient. Already a French naval base, Lorient had the facilities Dönitz needed, as well as numerous cafes and bars, and a red-light district. A special train loaded with replenishment supplies and ordnance, and the personnel to manage them arrived in Lorient at the end of June, and the first U-boat, U-30 docked a week later. U-30 had departed Wilhelmshaven on 8 June and arrived at Lorient on 7 July after a 30 day patrol which had accounted for 5 allied ships. She was repaired and resupplied in 7 days, departing on her next patrol on 13 July.
