Barysaw (officially transliterated as Barysaŭ, Belarusian: Бары́саў; Russian: Бори́сов, Borisov [bɐˈrʲisəf], Polish: Borysów) is a city in Belarus situated near the Berezina River in the Minsk Region. With a population of around 145,000, it lies around 74 km northeast of Minsk.
The Battle of Berezina (or Beresina) took place from 26 to 29 November 1812, between the French army of Napoleon, retreating after his invasion of Russia and crossing the Berezina (near Borisov, Belarus), and the Russian armies under Mikhail Kutuzov, Peter Wittgenstein and Admiral Pavel Chichagov. The battle ended with a mixed outcome.
Barysaw is first mentioned in the Laurentian Codex as being founded (as Borisov) in 1102 by the Polotsk prince Rogvolod Vseslavich (baptismal name Boris). During the next couple of centuries it was burned and then rebuilt slightly south of its original location.
