Since Khanenko’s regiment numbered only 4,000 soldiers, he asked for help from the Castellan of Podlasie, Karol Luzecki, with 2,500 cavalry and dragoons.

Khanenko and Luzecki joined forces on July 18, and marched towards the village of Czetwertynowka.

Their army consisted of a traditional Cossack tabor in the center, Polish cavalry on both sides, and dragoons in the back.

After a small skirmish, a Cossack unit loyal to Doroshenko was pushed beyond the Boh river.

The skirmish, due to the efforts of Khanenko and Luzecki, ended in a costly Polish-Cossack victory, as their losses were very high.
