Napoleon, isn't he the guy who lost 97% of his army in the winter?

There is a great graphic, drawn in 1869 by Minard, that shows the size of Napoleon's army over the duration of his campaign to attack Moscow. (The beige line is going to Moscow, the black line is the retreat.)

Napoleon starts out with a force of 422,000, and ends up with just 10,000. Given this fiasco, in the face of cold weather, how is Napoleon a good name for a furnace? (Or do I just know too much useless junk for my own good?)
