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. Polish cavalry continued the advance, but the opponent counterattacked, which resulted in heavy Polish losses.
The skirmish, due to the efforts of Khanenko and Luzecki, ended in Polish victory, but it was a Pyrrhic victory, as the losses were very high.
