How did Napoleon travel to and from Russia safely after the burning of Moscow?

It’s actually an interesting question. Given virtually his entire army was totally destroyed, and he was the most sought man in Russia, how could he possibly have survived? Of course, he might not have, and the French simply put a double in his place. This is a real possibility. I believe he had his own transport, his personal carriage and horses, and very loyal guards. That might have done the trick. He simply fled, leaving his entire army to freeze to death. That might explain this paradox. https://www.quora.com/unanswered/How-did-Napoleon-travel-to-and-from-Russia-safely-after-the-burning-of-Moscow
