Significance

In June 1812 Napoleon led a multinational Grande Armée of around 600,000 men across the Niemen River to compel Tsar Alexander I to return to the Continental System. The Russians refused a decisive engagement, retreating deep into their territory and devastating the land behind them.

After a bloody, indecisive clash at Borodino in September, the French occupied a largely abandoned and burning Moscow but found no surrender awaiting them. With supplies exhausted and winter approaching, Napoleon began a catastrophic retreat on 19 October. Harried by Cossacks, hunger, disease and bitter cold, his army disintegrated, suffering a perilous crossing of the Berezina in late November. Of the vast force that had invaded, only a small fraction recrossed the frontier; total deaths across the campaign are estimated in the hundreds of thousands. The disaster destroyed the myth of Napoleon's invincibility, emboldened his enemies, and marked the turning point that began the collapse of his European empire.
