Battle on the Nemiga River

[1] In retaliation, Vladimir attacked and pillaged Polotsk, killed Rogvolod, and took his daughter Rogneda by force, adding the city to his territorial possessions.

By 1021, Bryacheslav set his sights on Novgorod; he attacked and ransacked the city, but on the journey home, he was overtaken by Vladimir's son Yaroslav I the Wise, then ruling in Novgorod, on the banks of the Sudoma River; he was defeated and fled, leaving behind his Novgorodian captives and loot.

While his father had been an irritant to the Rus princes in the Middle Dnieper region, Vseslav's campaigns in the north were much more serious.

[6] The precise course of battle is unknown, though it has become legendary as a bloodbath; The Tale of Igor's Campaign referred to "the bloody banks of the Nemiga" being sown not with blessings but with bones.

However, in June, after the battle, the Yaroslav princes called for negotiations, “kissed the cross” (took an oath) and made promises of future safety; Vseslav was invited to Iziaslav's camp to celebrate the peace and was promptly arrested together with two of his sons and taken to prison in Kiev.
