BERESINA, or BEREZINA, a river of Russia, rising in the north of the province of Minsk, and falling into the Dnieper, after a course of 200 miles. It is connected with the Dwina by a canal, which thus establishes a communication between the Black Sea and the Baltic. The passage of the Beresina is celebrated as one of the most disastrous events in the retreat of Napoleon from Moscow. See FRANCE.
