Léon Werth, aged 36, served in the French army from August 1914 to August 1915. He uses Clavel to voice his anti-war position in this novel as well as in the one that immediately preceded it, Private Clavel’s War on War . Both are examples of modernist writing, based on the detailed notes Werth kept every day. Clavel’s war is presented as a character sketches, snatches of conversation, impressionistic notations, polemical arguments and interior monologue. In this follow-up novel, Werth portrays Clavel’s fellow-patients, nurses, and doctors in hospitals and convalescent homes, and his Parisian friends, all of whom have contrasting views on the war. Clavel soon learns he must conceal his anti-war attitude to avoid being informed on by a fellow-patient, nurse or doctor, with the result that he would be returned to the front, irrespective of his physical fitness.
Léon Werth was a French writer and art critic, a friend of Octave Mirbeau and a close friend and confidant of Antoine de Saint-Exupéry.
Werth wrote critically and with great precision on French society through World War I, colonization, and on French "collaboration" during World War II.
