Zone libre
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 "Zone libre" was placed under German military administration in November 1942, the network needed to grow to gather information in the whole of France. Hollard recruited hotel personnel and domestic workers working in requisitioned hotels or private houses to cater to German troops.
