According to Ben MacIntyre's "For Your Eyes Only: Ian Fleming and James Bond," "Among Fleming's more remarkable ideas were: scuttling cement barges in the Danube at its most narrow point in order to block the waterway for German shipping; forging Reichsmarks to disrupt the German economy; dropping an observer (possibly Fleming himself) on the island of Heligoland to monitor the shipping outside Kiel; sinking a lump of concrete off Dieppe with men inside it to observe the German coastal defenses; luring German secret agents to Monte Carlo and capturing them; and floating a radio ship in the North Sea to broadcast depressing and/or irritating propaganda to the Germans."
Although he collaborated with the Nazis, the Germans remained wary of Admiral Darlan due to his malleable loyalties and forced him to resign from his position as Admiral. He held several less important positions before being assassinated by a lone French Royalist in 1942.
Fleming's chauffeur listens to the song "Boum" by Charles Trenet on the radio, which was also heard on Silva's island in Skyfall (2012).
