The Russian army withdrew and retreated past Moscow. Napoleon entered the city, assuming its fall would end the war and Alexander would negotiate peace. However, on orders of the city's governor Feodor Rostopchin, rather than capitulation, Moscow was burned. After five weeks, Napoleon and his army left. In early November Napoleon became concerned about the 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. After the Battle of Berezina Napoleon managed to escape but had to abandon much of the remaining artillery and baggage train. On 5 December, shortly before arriving in Vilnius, Napoleon left the army in a sledge.
