This was a British operation by the Special Operations Executive to establish radio contact and organise resistance groups on the eastern side of the Oslofjord in German-occupied Norway (5 February/July 1942).
A two-man Norwegian party was delivered by sea and air in the form of E. N. Stenersen, the organiser, who arrived on 5 February by sea, and E. K. Jacobsen, the radio operator, who arrived on 27 March by air. Stenersen made initial contact with the local resistance organisation and was asked him to make his radio available. He also found a site for the radio operator, and in May escaped to Stockholm in neutral Sweden. In July Jacobsen was seized by the Gestapo, who attempted unsuccessfully to simulate his radio ‘fist’, but escaped in December 1942.
