Operation Bernhard was an exercise by Nazi Germany to forge British bank notes. The initial plan was to drop the notes over Britain to bring about a collapse of the economy, but the operation was closed in early 1942, about a year after its head, Alfred Naujocks (pictured), fell out of favour with his superior officer, Reinhard Heydrich. It was reopened in July as a counterfeiting operation to finance German intelligence operations. Prisoners were sent to Sachsenhausen concentration camp to work under SS Major Bernhard Krüger, producing British notes until mid-1945 worth between £130 and £300 million. Counterfeit notes from the operation were used to pay the Turkish agent Elyesa Bazna—code-named Cicero—for his work in obtaining secrets from the British ambassador in Ankara, Turkey. Another £100,000 helped to free the Italian leader Benito Mussolini in the Gran Sasso raid in September 1943. The operation was dramatised in a 1981 BBC comedy-drama miniseries, Private Schulz, and in a 2007 Austrian film, The Counterfeiters. (Full article...)
