The Sacred Squadron was formed on 23 November 1812, by the Bobr River (perhaps at Borisoff, in modern Belarus) to serve as Napoleon's bodyguard. It was disbanded on 10 December 1812, in Kowno (modern Kaunas, Lithuania). It therefore served during the crossing of the Berezina (26-29 November), and continued to exist for a few days after Napoleon's departure for Paris on 5 December.
