During the
Khmelnytsky Uprising, Chortomlyk Sich guarded the then southern borders of Ukraine. Cossacks of the Sich took part in
Bohdan Khmelnytskyi's campaigns, excelling in the
battles of Zhvanets (1653),
Horodok (1655), during the second siege of
Lviv (1655), etc. The national recognition of the Chortomlyk Sich spread during the time of kish otaman
Ivan Sirko (1659—1680), who lived exclusively in the sich for 17 years and was elected a kish otaman more than 15 times, favoring his military merits. In particular, he became famous for the defeat of the 60,000-strong Ottoman-Tatar army, which suddenly attacked Chortomlyk Sich on New Year's Eve in 1675; as well as the Crimean campaign of 1676, when the Cossacks led by Sirko for the first time crossed the
Syvash bay and threatened the Khan's capital
Bakhchysarai. After the defeat of Ivan Mazepa and his supporters at the
Battle of Poltava in 1709, the Chortomlyk Sich was destroyed by the Moscovite armed forces together with the capital of
Cossack Hetmanate,
Baturyn and other Ukrainian cities. == References ==
