Every one of these armies had enough soldiers to win. Some had overwhelming numerical superiority. Several had better weapons, better training, or better generals than their opponents. None of that mattered, because none of them had enough supplies. The history of warfare is littered with campaigns that failed not because of tactical defeat on the battlefield, but because the army ran out of food, fuel, ammunition, or water before it could fight. These are the 10 most consequential logistics failures in military history — battles that were lost before they started.
1. Napoleon's Invasion of Russia (1812) — The Army That Ate Itself

Napoleon crossed the Niemen River into Russia in June 1812 with 685,000 soldiers — the largest army Europe had ever seen. He expected a decisive battle within weeks. The Russians refused to give him one, retreating deeper into their territory and burning everything behind them. Napoleon's supply lines, already stretched thin, collapsed entirely.
The Grande Armée's logistics plan relied on foraging — living off the land. This had worked across the fertile farmlands of Western Europe. It was catastrophically inadequate for Russia's vast distances and scorched-earth tactics. Horses died by the tens of thousands from lack of fodder, immobilizing the artillery and supply wagons. Soldiers ate their own horses, then resorted to eating their leather equipment. Disease — typhus, dysentery, and starvation — killed far more men than Russian bullets. Of the 685,000 who crossed into Russia, fewer than 120,000 came back. The logistics failure didn't just lose the campaign. It destroyed the most powerful army on earth.
