When the Zaporozhian Cossacks during the Khmelnytsky Uprising reached the Belarusian lands of the PolishâÂÂLithuanian Commonwealth in 1648, it forced the army of the Grand Duchy of Lithuania of the PolishâÂÂLithuanian Commonwealth to act and start a military actions against the Zaporozhian Cossacks in 1649.
The strong forces of the Crown Army numbered around 11,000 men under the command of Prince Janusz Radziwià Âà  moved to fight against the Zaporozhian Cossacks. In February 1649, Janusz Radziwià Âà  left the PolishâÂÂLithuanian camps in Turiv and set off towards the city of Mazyr with only a cavalry. The entire PolishâÂÂLithuanian CommonwealthâÂÂs forces were preceded by an advance guard commanded by Adam Pawà Âowicz, which included, among others, three Crimean TatarâÂÂs banners which was commanded by Dzienaj Romanowski, Dawid Kià Âski and Dowgiaà Âà Âo. In the night 8âÂÂ9 February 1649, Adam Pawà ÂowiczâÂÂs bivouac PolishâÂÂLithuanian troops were unexpectedly attacked by a group of several hundred Zaporozhian Cossacks. On the morning of 9 February 1649, the main forces of the Crown Army came to the aid of the defending troops of the advance guard, which caused the Zaporozhian Cossacks to retreat to the Mazyr fortress. The attempt to capture the Mazyr fortress on the march failed, so the Prince Janusz Radziwià Âà  hurried the entire cavalry (including the reiters led by Ganchof) and sent it to attack the earthworks. After a hard battle, the Mazyr fortress was captured by the PolishâÂÂLithuanian CommonwealthâÂÂs forces.
The victorious Crown Army started burning the city of Mazyr and its inhabitants suffered serious casualties and losses because, according to Bogusà Âaw Maskiewicz, a participant in the events, the German mercenary reiters were particularly cruel to the civilian population of the captured city of Mazyr. After the fighting ended, the captured Zaporozhian Cossack prisoners were beheaded and impaled, including a commander of the Zaporozhian Cossacks Colonel Mykhenko, who was killed in the battle.
