Is paris burning? (1966)

Near the end of World War II, General Dietrich von Choltitz receives orders to burn down Paris if it becomes clear the Allies are going to invade, or if he's unable to maintain control of the city. After much contemplation, Choltitz ignores orders, enraging the Germans and giving hope to various resistance factions that the city will be liberated. Choltitz, alongside Swedish diplomat Raoul Nordling, helps a leader organise his forces.
