The Battle of Sich took place between the Ottoman-Crimean army and the Zaporozhian Cossacks, during the Ottoman-Crimean campaign into the Sich, at night on 19 December 1674. Detailed description of this battle only appears in Velychko's chronicle.
Sultan Mehmed IV and Khan Selim I Giray planned a campaign into the Sich with the goal of destroying it, thus ending the frequent Cossack campaigns and raids of Ivan Sirko into their lands. In autumn of 1674, Sultan sent 15,000 Ottoman Janissaries to Crimea. In total, 15,000 Janissaries and 40,000 Tatars were to take part in the campaign.
Turkish-Tatar army launched their campaign into the Sich once the rivers froze, at night to avoid getting detected. The Khan used captured Cossacks to gain access into Sich, expecting to take Cossacks by surprise as they were asleep. However, they were noticed by a Cossack named Shevchuk or Chefchika, who alerted his comrades, and made the presence of intruders in the Sich known to the other 150âÂÂ350 Cossacks, which allowed them to react on time and equip their guns. Cossacks launched an attack on the Turkish-Tatar army, firing at them with muskets from all directions, which put the Turkish-Tatar army into the state of disorganized panic. Each shot killed 2âÂÂ3 Janissaries due to lack of space between the Sich Kurins, not allowing Janissaries to move freely. Janissaries couldn't fire back either. Cossacks took advantage of the panic among Janissaries, taking out their sabres and getting into hand combat with them. As a result, nearly all Ottoman Janissaries were wiped out. Khan Selim I Giray hastily retreated back to Crimea with remnants of Turkish-Tatar army before the 2,000 Cossack cavalrymen could catch up to them.
Cossacks came out victorious. 13,500 Turks were killed and 150 were captured. Tatars also suffered heavy losses. Cossacks suffered 50 killed and 80 wounded. Cossacks disposed of enemy corpses by throwing them in wholes of frozen river, under the ice. As a result of this battle, Ottomans ceased their attempts of destroying Cossacks militarily. Later, Ivan Sirko with Cossacks sent a reply to Khan Selim I Giray. They wrote:
Nonetheless, Sirko agreed to the Khan's request to release 150 Janissary captives as part of ransom. Initially, Sirko blamed Petro Doroshenko for the attack in a separate letter, but Doroshenko in his reply assured Sirko he has nothing to do with it. Ivan Sirko wanted revenge for the attack on Sich, this inspired his Crimean Campaign in 1675.
The historicity of this battle initially risen doubts due to its only mention appearing in Velychko's chronicle. However, it was later discovered that this battle is also mentioned in chronicle of , but in less detail.
