Also: "An army marches on it's stomach".

Or in the case of Napoleon in Russia when they ran out of supplies, it marches on the 200,000 dead corpses of starved and frozen to death soldiers, with some help from countless slaughtered horses killed for food; and boot leather boiled soft enough to chew.

That's what you get when your supply plan buffers 50 days for rapid assault & victory while the enemy retreats, retreats, retreats, scorched-earth all the way. Hell, the Russians torched the entire city of Moscow to deny it to the enemy so it couldn't be used as a stop over on the way to St. Petersburg.

That was pretty much the end of Napoleon's campaign in Russia, and the beginning of his downfall. You don't get 500,000 troops killed in a single campaign and come home to fanfare and accolades.

In fact his failures during that campaign foreshadowed his downfall with a (failed) military coup. This was actually slightly convenient for Napoleon, giving him a reason to get the heck out of Russia before the final end came: extremely fortunate since the very small remaining body of troops retreating back west were not especially happy with their failed commander.
