the beginning of 1651, King of the Commonwealth Jan II Casimir violated the terms of the Peace of Zboriv by invading the territory of the Hetmanate. The Cossack army led by B. Khmelnytsky went to meet him. While the hetman opposed the Poles near Berestechko and Bila Tserkva, the left-bank Chernihiv and Nizhyn regiments, led by Chernihiv colonel Martin Nebaba, defended the northern border of the Hetmanate from Janusz Radziwill's Lithuanian troops. The following events are covered in detail in the Chronicle of the Seer. M. Nebaba's army, leaving a guard near the crossing of the Dnieper, encamped near Ripky. And when J. Radziwill's army began the crossing, the Cossack guard let the colonel know about it. After the battle, the Cossack camp, food and weapons were seized by J. Radziwill's soldiers. In 1651, under the terms of the Peace of Bila Tserkva, the Nizhyn Regiment was liquidated. In January–February 1652, 16,000 Polish troops entered the lands of the revived Chernihiv Voivodeship. Thus, the brother of the Crown Hetman of the Commonwealth M. Kalinowski, Samuel, was stationed in Nizhyn for the winter, and "the troops who had a large army with him, spread in various cities in the Dnieper and Zadesen." Taking advantage of the liquidation of the Nizhyn Regiment, Polish official Adam Kisiel sent Mr. Luh, the governor, to his lands in the Nizhyn region. This caused a new wave of discontent and during the skirmish in Kobyzhchy Mr. Luh was killed. Colonel L. Sukhinya of Nizhyn punished those involved in the murder, but the Cossacks, dissatisfied with this, appealed to Colonel Stepan Pobodail of Chernihiv to address their deputy as hetman. S. Pobodailo agreed and went to B. Khmelnytsky. This visit of the colonel to the hetman led to the fact that B. Khmelnytsky, having studied the situation in detail, executed a number of persons involved in illegal actions. It is quite possible that L. Sukhinya was among them, because after these events his name is no longer mentioned, and Ivan Zolotarenko was appointed the new Nizhyn colonel. The following year, 1653, the Cossacks of the Pereyaslav, Chernihiv, and Nizhyn regiments, led by Colonel I. Zolotarenko of Nizhyn, again opposed the Lithuanian troops on the northern border of the Hetmanate. The hetman also sent some Tatar detachments to help I. Zolotarenko. There were no major battles, and the war of 1653 in the Nizhyn region was marked by
