Army of Shadows: Army of Shadows (French: L'armée des ombres ) is a 1969 French film directed by Jean-Pierre Melville.  It is a film adaptation of Joseph Kessel's 1943 book of the same name, which blends Kessel's own experiences as a member of the French Resistance with fictionalized versions of other Resistance members.  "Army of Shadows" follows a small group of Resistance fighters as they move between safe houses, work with the Allied militaries, kill informers, and attempt to evade the capture and execution that they know is their most likely fate.  While portraying its characters as heroic, the film presents a bleak, unromantic view of the Resistance.
