Marshal Mannerheim, celebrating his 75th birthday on 4 June, 1942, received a surprise visit by Adolf Hitler. Thor Damen, a sound engineer working for the Finnish Broadcasting Company, tossed a microphone on the parcel shelf of the ceremonial carriage, allowing for the two men’s conversation to be covertly recorded.
