What happened November 1812 AD

Napoleon and his army left. In early November Napoleon got concerned about loss of control back in France after the Malet coup of 1812. His army walked through snow up to their knees, and nearly 10,000 men and horses froze to death on the night of 8/9 November alone.

The French suffered in the course of a ruinous retreat, including from the harshness of the Russian Winter. The Armée had begun as over 400,000 front line troops, with fewer than 40,000 crossing the Berezina River in November 1812. The Russians had lost 150,000 in battle and hundreds of thousands of civilians.
