This opportunity came in 1775, when the
Russo-Turkish War (1768–1774) ended, which the Cossacks helped Moscow win, and the Cossacks became unnecessary. On April 23, 1775, the Council of the Imperial Court decided to liquidate the Sich. In early June 1775, Russian troops under the command of Russian General of Serbian descent
Peter Tekeli, returning from an Ottoman campaign, set off from the
Fortress of St. Elizabeth and suddenly surrounded Sich. The Cossacks did not expect such a development, and therefore in
Zaporozhzhia at that time there were very few soldiers: only a few thousand
Cossacks in the Sich, while the rest went to
palankas and winter quarters after the war. Instead, under the command of Peter Tekeli, there were significant forces: 10 infantry and 13 Don Cossack regiments, 8 regiments of regular cavalry, reinforced by 20
Hussars and 17
Pikiners squadrons. Peter Tekeli announced an imperial decree to eliminate the Zaporozhian Sich. The Sich society, given the very unequal forces, had no choice but to surrender to the will of the victors. It was clear that the resistance of several thousand besieged Cossacks would be in vain, while the breakthrough of other Cossack troops to the besieged Sich was almost impossible for many reasons. Among these reasons is the large number of Russian troops and the fact that almost all the Cossack officers were in the Sich, thus leaving Cossacks who were not surrounded without command. A council headed by Kosh Ataman
Petro Kalnyshevskyi convened at the Sich, and fierce debates erupted in an attempt to find a way out of the hopeless situation. The council decided not to shed Christian blood and voluntarily laid down its arms in front of the
Muscovites. In addition, the Cossacks feared, in case of resistance, a bloody revenge on their families (the Sich still had old Cossacks who remembered the events of 1709, when
Peter I conducted a brutal punitive expedition against Ukraine, including the infamous
Baturyn massacre that became the culmination of those horrible events). Zaporozhian Cossacks took part in many campaigns of the Russian army and witnessed the brutality of Russian troops in storming enemy settlements. As the participants in the events at the Sich recalled, their '''' did not want to surrender to Catherine at all, but other Cossacks said: “No, brother, we have parents and children: a Muscovite will stub them". So they decided and surrendered. == Consequences of the liquidation of the Zaporozhian Sich ==
