"This letter is an incredible insight, we never see Napoleon emotively speaking in this way before," says Chataignier. "Only in letters to (his wife) Josephine did he ever express anything near to emotion. Moscow knocked him."
"This letter is unique. Not only is it all in code, but it's the first time we see this different Napoleon. He went into Moscow in 1812 at the height of his power. He returned profoundly weakened. In Moscow, the Russians had fled days before and burnt down the city. There was no victory for Napoleon, nor were there any provisions for his starving, dying army," says Jean-Christophe Chataignier of the auction house.
