On 20 July Doroshenko resumed the siege of the Polish garrison at Bila Tserkva and sent his younger brother Gregory and 2,000 Cossacks to Podolia. He sent the Kalnitsky regiment to Crimea to help Adil Giray against Zaporozhians.

Most of the Budjak Mirzas who were with Gregory Doroshenko, on learning of the approach of the Polish militia, hastily left their ally and returned to their camps. Grand Crown Hetman Jan Sobieski advanced against Doroshenko and the Crimean horde. On 26 August at Bratslav the Polish army routed the Cossack and Tartar troops.

Despite the victory, Sobieski withdrew to Bar, where he arrived on 30 August.. How many days passed between Doroshenko resuming the siege at Bila Tserkva and his withdrawal to Bar?
