Preoccupied by the Venetian threat in the Eastern Mediterranean, the Ottoman Empire could not provide them with concrete assistance, but encouraged the formation of a joint Tatar-Cossack front against the Poles and offered diplomatic support, Sakul said, adding that the journals of Evliya Çelebi, a famous Ottoman explorer, provided a beaming account of the Ukrainian forces as "our Cossack brothers."
"Obviously, the Ukrainians were grateful for the Ottoman support. So much so that renowned Cossack Hetman Petro Dorosenko was given the title of Sancakbeyi (district ruler) by the Ottoman Empire and Sultan Mehmet IV sent reinforcements to aid the Ottoman army during the Siege of Kamenets (against the Polish) in 1672."
