Operation Arquebus

'Arquebus' was a British operation by the Special Operations Executive to organise resistance groups in the Haugesund area of German-occupied Norway, establish radio contact, and investigate the possibility of brining in explosives for an attack on the aluminium plant at Saudasjøen to the north of Stavanger (15 October 1941 onward).

A two-man Norwegian party (S. Andersen and B. Haarvardsholm) was delivered by sea, and Haarvardsholm was lost whilst returning to the UK by sea in November, but Andersen remained in Norway for the rest of the war. The operation’s radio was damaged and therefore contact was made in April 1942 through a Special Intelligence Service station. A new radio was eventually sent from Stockholm in neutral Sweden during October 1942 and this allowed the establishment of full contact.
