Founded in early 1944, Maquis Bernard's was based in the forest of Saint-Brisson. It was commanded by Louis Aubin, a retired policeman, aka Bernard, and Joseph Pelletier, aka Joseph. In the summer of 1944, the Maquis set up camp in the forest of Coeuzon, at Ouroux-en-Morvan, with around one thousand men. The Headquarters of the Resistance in Nièvre also based its command post here, and was used by the prefect Jacquin, appointed by General de Gaulle, making Ouroux-en-Morvan the clandestine prefecture of Nièvre.
