In 1675, in last days of July, Sirko announced his intentions to Cossacks about the planned campaign to "shake up the whole Crimea mercilessly".
[4] Sirko wanted to take revenge on the Crimean Tatars and Ottomans for their attempt to destroy Sich the previous winter.
[11] In the summer of 1675, the Russian government decided to conduct a raid on the territory of the Crimean Khanate, for which they allocated a detachment of Prince Cherkassky (747 people, however, due to illness and desertion, at the time of the outbreak of hostilities, he numbered about 546).
Due to their small numbers, the Russians began negotiations with Ataman Sirko, persuading him to allocate 1,500 to 2,500 men.
[11][12] Khan Selim I Giray heard about the news of the enemies in Crimea on their way to the capital of the Crimean Khanate, Bakhchysarai.
Khan thought that the Tatars in Crimea managed to reorganise and were coming to his aid, so he once again attacked Sirko's army, but suffered another defeat with heavy losses.
[11] Sirko with his Cossacks and captives got a safe distance away from Crimea to the place called Chorna Dolyna, also known as Black Valley.
As Sirko stood over corpses of the executed captives, he was quoted to have said:[15] Brothers, forgive me, but it is better that you should lie here awaiting the terrible judgment of God than go back to Crimea to help them [Tatars] increase in numbers and risk the eternal damnation of your souls.The Crimean-Ottoman forces suffered heavy losses.
And because your deed upset us and gave us the disappointment, then reconcile ancient ancestors and our brethren, we decided to try take revenge on your Khan mercy and all the Khanate, but not secretly, but openly, chivalrously.Ivan Sirko sent a letter to Hetman Samoylovych describing the success of his campaign with his allies, claiming to have avoided serious losses.
