Under the pseudonym "Pointer", Girard was the regional head of the Alliance or "Arche de Noé" resistance network in occupied France from 1940 to 1945, the only network whose supreme commander was a woman, Marie-Madeleine Fourcade (Alias "Hérisson"). This network was notable for giving almost all of its three thousand agents codenames based on animals : Bleu d'Auvergne, Setter, Labrador, Bichon, Abeille, Aigle... Divided up by region, the network's central command was "Hôpital" (centre-west sector), which Girard led from 1943 to September 1944. In 1944, his sector numbered 185 main agents across 16 départements, from south of the Loire to north of the Garonne, a sector particularly marked by the Tulle and Oradour-sur-Glane massacres. Its agents were from diverse social backgrounds – the mayor of La Rochelle and colonel in the reserve Léonce Vieljeux, the student Roland Creel, the vicar of Tulle cathedral Charles Lair, the usselois doctor Jean Sirieix, the intelligence commissioner Henry Castaing, the briviste businessman Pierre Bordes, the secretary-general to the council of Guéret Roland Deroubaix, the creusois lawyer René Nouguès or the electrician Vincent Renaud, as well as civil servants, peasants, surgeons, railway workers, architects, and ushers.
