Abstract: In his chronicles for L’Écho de Paris from 1914 to 1920, M. Barrès sought to reconstruct an “edifice of friendship”. This project made him attentive to the redistribution of the positions of authority which conflict brought about, and made him redefine his discursive legitimacy. He conceived of his role as that of an interpreter reproducing or amplifying discourses coming from all social horizons, and he put his personal authority at the service of those who had experienced combat.
