Book excerpt: The Battle of Moskova has given rise to a multitude of partisan and controversial theories about the validity of the victory, the mistakes the Emperor made, his behaviour, the number of soldiers in the two opposing armies, the relative scale of the losses, and what happened after the battle. The author examines in great detail Napoleon's 1812 campaign, attempting to get closer to the truth by consulting extensive statistics and witnesses' reports in the archives. The evolution of the battle is described with plates of uniforms, flags, paintings of the battle and new color maps.
