May 1, Tatars and Cossacks decided to launch an attack from two sides on the Polish camp, after the initial firing of the camp, the Cossacks began their attack. They tried to distract the defenders from Tugay Bey attacking them from behind, but the Tatars were late and attacked at a time when the Cossacks (after two unsuccessful attacks) had already withdrawn. This made it possible to effectively repulse the Tatars. Later Khmelnytsky and Tugay Bey still tried (4 or 5 times) to attack the Poles, but each time unsuccessfully. After a six-hour struggle, Tatars and Cossacks suffered significant losses and retreated. On the night of May 1 to May 2, the Cossacks built near the Poles a rampart and placed their cannons, but at dawn, the defenders quickly attacked, seized the position, and destroyed the fortifications. A period of blockade began, interrupted by frequent fighting (during the day attacked by Tatars, and at night by Cossacks).
