Sheremetev capitulated after the battle of Chudniv and ordered Baryatinsky to withdraw from the ancient city according to his new treaty with the Poles.
At the same time, discontent began to rise in the Polish army due to missing payments, leading to widespread desertion.
Baryatinsky's determined action allowed to alleviate the consequences of the Chudniv battle and to keep a significant part of Ukraine unter Russian control until the end of the war.
