[1] In February, the Crown troops led by Marcin Kalinowski began to concentrate in the vicinity of Bar, and then, under the influence of news of peasant uprisings, they moved towards Bracław.

[1] On the morning of 11 March 1651, Polish troops led by Marcin Kalinowski and Liantskoroński clashed with Cossacks commanded by Ivan Bohun near Vinnytsia.

The siege of Vinnitsa lasted until 20 March, during which the Cossacks successfully repulsed the attacks, using both fortifications and brilliant tactics.

Attempts at negotiation failed, as the Cossacks refused to surrender Bohun and their weapons, and on hearing of incoming aid decided to continue defending.

In the end, the Polish army, weakened and lacking in morale, retreated, avoiding total defeat by crossing the Southern Bug.
