Unanimously celebrated as an authentic representation of French railroad workers' resistance against the Germans during the Occupation, René Clément's La Bataille du rail (The Battle of the Rails, 1945) was a valuable piece of ideological capital in the wake of France's liberation. Through a close reading of the film's production and reception, this article shows that the film's heroic blueprinting of the Resistance was the result of mediation between two opposing points of view: that of the Marxist Left, which sought to portray the Resistance as belonging to the working class, and that of the Gaullists, who were intent on promoting the myth of an idealized "True France" without class or ideological divisions and united in its opposition to the Germans.
