Who wanted the Russian army to negotiate peace?, Context: The Russian army withdrew and retreated past Moscow.

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. After Battle of Berezina Napoleon succeeded 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.
