In the spring of 1944, the town of Port-en-Bessin was occupied by the 1st Company of the Grenadier-Regiment 726 (716. Infanterie-Division). Its fishing port is located below a large cliff that is set up for defense by the Germans. On June 6th, at 9:30 am, the landing did not proceed as planned for the British commandos who suffered very heavy losses. Immediately after the fighting, the Allies began work to rehabilitate the port. The aim is to carry out landings of supplies, but also to set up a pipeline system: PLUTO (Pipe-Line Underwater Transport of Oil).
