Springing from the author's first-hand experience as an ambulance driver and Red Cross worker during World War I, this autobiographical first novel is noteworthy for its vivid and colorful evocation of France at that time and for its passionate indictment of war.

The author's disillusionment with war for a time turned him toward socialism and against capitalism. Ultimately, after being labeled "pro-German" and "pacifist", the author concluded that the quasi-religion of Marxism turned loose more brutal aggression than "poor old Capitalism ever dreamed of".
