Newly released MI5 information shows that the allied defeat in Norway in 1940 may have been caused by a German espionage triumph:
[Marina] Lee is said to have infiltrated the headquarters of the British Expeditionary Forces in Norway and obtained information about the plan drawn up by British commander Gen Auchinleck.
German commander, Gen Eduard Dietl, who was holding the Norwegian port of Narvik, was reportedly considering a withdrawal, but the disclosure of these details meant his forces could block the Auchinleck plan.
British, French and Norwegian troops were later forced to withdraw from German-controlled Norway.
Born in St Petersburg, Russia, Lee was married to a Norwegian communist and had trained as a ballerina before becoming “a highly valued and experienced German agent”, according to the files.
She is described as “blonde, tall, with a beautiful figure, refined and languid in manner” and reportedly spoke five languages.
One account says she personally knew Stalin — leading to conjectures she was working for both Berlin and Moscow who, at that time, were on the same side, our reporter says.
