One month after Napoleon Bonaparte's massive invading force entered a burning and deserted Moscow, the starving French army is forced to begin a hasty retreat out of Russia.
Following the rejection of his Continental System by Czar Alexander I, French Emperor Napoleon I invaded Russia with his Grande Armée on June 24, 1812. The enormous army, featuring more than 500,000 soldiers and staff, was the largest European military force ever assembled to that date.
During the opening months of the invasion, Napoleon was forced to contend with a bitter Russian army in perpetual retreat. Refusing to engage Napoleon's superior army in a full-scale confrontation, the Russians under General Mikhail Kutuzov burned everything behind them as they retreated deeper and deeper into Russia. On September 7, the indecisive Battle of Borodino was fought, in which both sides suffered terrible losses. On September 14, Napoleon arrived in Moscow intending to find supplies but instead found almost the entire population evacuated, and the Russian army retreated again. Early the next morning, fires broke across the city set by Russian patriots, and the Grande Grande Armée's winter quarters were destroyed. After waiting a month for a surrender that never came, Napoleon, faced with the onset of the Russian winter, was forced to order his starving army out of Moscow.
During the disastrous retreat, Napoleon's army suffered continual harassment from a suddenly aggressive and merciless Russian army. Stalked by hunger and the deadly lances of the Cossacks, the decimated army reached the Berezina River late in November but found its route blocked by the Russians. On November 26, Napoleon forced a way across at Studienka, and when the bulk of his army passed the river three days later, he was forced to burn his makeshift bridges behind him, stranding some 10,000 stragglers on the other side. From there, the retreat became a rout, and on December 8 Napoleon left what remained of his army to return to Paris with a few cohorts. Six days later, the Grande Armée finally escaped Russia, having suffered a loss of more than 400,000 men during the disastrous invasion.
