If you haven't read it, read Is Paris Burning? by Larry Collins and Dominique LaPierre. True story about the French Underground in Paris working with German General von Choltitz to save the city from Hitler's order to burn it to the ground. I couldn't put the book down once I started reading it. Very interesting and well written documentary.

Edit: I didn't read it in French, but shouldn't be too hard to find the French version.
