41,714[4] At least 1,462 including dead, injured, deserted [6] Up to 2,000 dead[6] Russo-Lithuanian War Swedish stage Báthory's campaign The siege of Polotsk (Russian: Осада Полоцка, Polish: Oblężenie Połocka, Belarusian: Аблога Полацка) was a siege by forces of the Polish–Lithuanian Commonwealth under Stefan Bathory on the Russian-held city of Polotsk.

Polotsk had been captured and heavily fortified by the Russians under Ivan the Terrible in 1563 because the river Dwina, which led to the key city of Riga, flowed through it.

Hungarian soldiers, led by Caspar Bekes, Polish soldiers, led by Mikolaj Mielecki, and Lithuanian soldiers, led by Mikolaj Radziwill, converged at the Dzisna fortress, joined Bathory's men, and moved on to Polotsk, with a total force of about 42,000.

The primary focus was on the central fortress: first with artillery, which failed because it only punctured the wooden walls, then with cannons, and eventually with fire.

[9] After taking the city, Bathory's forces then moved to besiege Velikiye Luki.
