Lille Society of Pigeon-fanciers

La Societé colombophile lilloise, the Lille Society of Pigeon Fanciers, was a society in northern France, with hundreds, if not thousands, of members. Feldgendarmerie Sergeant Adolf Hitler, who had worked with carrier pigeons in the war, knew that the society was likely to be a hotbed of espionage and subversion against the Kaiserreich. He joined the Society in his undercover persona of Koppensteiner, a merchant from Antwerp. At one meeting of the Society, Hitler heard about Madame Lea's meeting house, and found the clue that allowed him to apprehend Jacques Doriot.
