Creation and organisation
The Réseau AGIR was created by Michel Hollard in 1941.

(S.I.S.).
During the war, the network was codenamed "''Z 165''" after the codename given to Hollard himself by the ''Intelligence Service''. ''AGIR'' or ''Réseau AGIR'' only emerged after Hollard's return from the
Liberation of France.
Early 1941, Hollard became the
concessionaire for the Seine department for the "Maison ''Gazogène Autobloc''", headquartered in Dijon, that, among other things, produced
wood gas generators for automobiles and supplied its clients with
charcoal
Charcoal is a lightweight black carbon residue produced by strongly heating wood (or other animal and plant materials) in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, ca ...
. Hollard was allowed to travel in search of wood nationwide and purchase wood to turn it into charcoal to preserve the increasingly scarce fuel in occupied France.
In 1941, Hollard traveled to the French Free Zone and crossed the Swiss border for the first time to offer his services as a spy to the British embassy in

. He was greeted icily despite intelligence about France's wartime automotive manufacturing capabilities that he had brought with him to show his goodwill. When he came back a month later, the second meeting was much warmer since the British military attaché had made the necessary checks about him. Hollard was tasked to report the position and description of the German forces in the French
Occupied Zone, especially the armored divisions. He committed to delivering intelligence every three weeks.
His job enabled him to travel around France using his job as a cover. Mostly traveling by train, he primarily established contacts with railway employees who, due to their work, had knowledge of the occupying forces' activities or knew how to obtain it.
From the very beginning, Hollard insisted that all actions should be organized through personal contacts only and that the exchange of researched material should only be forwarded or handed over to him personally. He distrusted the means of communication, such as the telephone or even radio, and saw in it a source of vulnerability for the network for the enemy. AGIR used signals with basic code like e.g. an open barn door indicated a Swiss border clear of soldiers. Entirely self-sufficient, the network did not rely on parachute drops or wireless transmitters. Intelligence was collected and sent to Switzerland every 3 weeks.
Hollard paid for the AGIR expenses, out of his pocket, until the British intelligence recognized the importance of the information collected by the network and offered to finance it. The network could rely on safe houses to cross the Swiss border and a safe place near

Early 1942, Hollard had recruited a total of 6 agents, distributed throughout the Occupied Zone, to report the movement of German forces as requested by the British. All of them were personally financed by Hollard. The network could also rely on volunteers to gather information on German facilities like aerodromes and factories. Railway employees and
station masters also played an important to report changes in enemy positions. When the ''

AGIR prepared a more detailed report in October about Bois Carré, which is located 1.4 km east of
Yvrench, that claimed it had "a concrete platform with the center axis pointing directly to London". AGIR reconnoitered 104 V-1 facilities and helped pinpointing the
Watten bunker, the first V-2 launching site.
AGIR also provided sketches of V-1 launching sites such as one by André Comps of Bois-Carré. It was labeled "''
Yvrench'' ''B

At the same time, André Bouguet, SNCF station director and AGIR informant, noticed transports that led north via Rouen. The destination of these transports was the
Auffay train station. With the help of René Bourdon, the station manager there, and his assistant Pierre Carteron, Hollard was able to penetrate a shed of the local sugar factory in which the transported V-1 were stored, hidden under a
tarpaulin and made precise dimensional sketches of the devices. The S.I.S. found an astonishing resemblance to Danish Lt-Colonel
Hasager Christiansen's sketch that he had made of an aircraft that crashed on

Thanks to Hollard's reports and information from his agents of the Réseau AGIR, the V1 launch sites located in the North of France, across North-Eastern Normandy to the Strait of Dover, were systematically bombed by the Royal Air Force between mid-December 1943 and March-end 1944, as a part of the
