[1] The operation aimed to make contact with local resistance groups in the Oslo area and to sabotage shipping.
As preparation for an invasion in Scandinavia in 1944, SOE began to attack industrial targets and coastal shipping in German occupied Norway.
Fish oil factories that used gylcorel in explosives had already been targeted by the British as early as 1940 and other missions had been carried out against the German nuclear program and to damage train lines.
Three SOE operatives from Company Linge; Tor Sternersen, Martin Olsen and wireless telegrapher Oddvar Sandersen dropped into Norway on 23 January 1943.
They made contact with Milorg and set up 4 'X-groups', which were groups of six men trained in silent killing, especially the elimination of informers.
