The first F Section agent successfully despatched to France was the radio operator Georges Bégué, who was commissioned in the British Army under the alias of George Noble. He dropped by parachute between Valençay and Levroux on the night of 5th-6th May 1941 under the code name BOMBPROOF, chosen (before the series of professions and trees/plants had been decided upon) because he had survived a bomb dropped during the London blitz, which had killed two of his friends and badly injured a third. Bégué's mission, which he completed swiftly, was to contact Max Hymans, at one time member of parliament for the Valençay constituency, whose country house was nearby. Bégué was able to report that Hymans was willing to work in co-operation with London and support the formation of local resistance groups, whereupon Pierre de Vomécourt was parachuted to the area with the code name AUTOGIRO to set up the first F Section circuit with Bégué as his radio operator. AUTOGIRO was active until early 1942, when the circuit was broken up after the arrest of Pierre de Vomécourt, who survived the war in Colditz. Georges Bégué escaped into Spain and regained London, where he worked on F Section's staff in charge of radio communication with agents in the field. He is credited with the invention of the system of messages personnels broadcast in the overseas services of the B.B.C.
Georges Bégué was followed into the field by more than four hundred F Section agents, 39 of them women, who from May 1941 to August 1944 landed from the sea or from aircraft or dropped by parachute to serve as circuit organisers, liaison officers, radio operators, arms and sabotage instructors or couriers. Between them they set up circuits which eventually covered most of France.
