 The main demand voiced by Fedorovych and his supporters—that the Cossack privileges routinely guaranteed to the limited number of registered Cossacks should be granted to all runaway peasants who claimed Cossackdom—was rejected and, according to a narrow compromise, the Cossack register was enlarged from six to eight thousand.In return, Koniecpolski demanded that Fedorovych be delivered into Polish custody.Fedorovych, uncertain of the decision that would be reached, over his head, by the "compromising" faction of Cossack leadership, left Pereiaslav along with other Cossacks dissatisfied with the agreement and headed for the Cossack stronghold of the Zaporizhian Sich.
