The sources do not mention any 1677 letter from Ivan Serko (Sirko) saying the Cossacks would not separate from Moscow, so the claim can be neither confirmed nor refuted.

What was said

… They went out of their way to save Turkey um bye sending Circle away. So that's, and throughout all of this, Circo tried to enlist the assistance of Samolovich on the on the left bank. After a while, Circo did endorse the pro moscow, um, but even said in a letter of 1677 that we aren't going to separate from you.

What we found

Context. Soloviev's history quotes a letter from Serko to the tsar in the context of his 1673 visit to Moscow, in which he pledges loyal service, but it does not mention 1677 or separation from Moscow.[1]

Context. A Cossack letter from Sirko to Tsar Alexei, dated to the year 172 in the source's calendar, professes loyal service to the tsar, but it is not dated 1677 and does not contain the claimed separation statement.[2]

Context. The Encyclopedia of Ukraine entry describes Sirko's 1678 military action with the Russian army, his later anti-Muscovite stance after 1667, and his preserved letters to Doroshenko (1673) and the Crimean khan (1679), but no 1677 letter to Moscow.[3]

Context. Wikipedia's entry on Sirko covers his 1659 election as Kosh Otaman, his alliance with Russia, and the later letter to the Ottoman sultan, with no mention of a 1677 letter about not separating from Moscow.[4]
