In response, Ivan Vyhovsky, the general scribe ("pysar") of the Hetmanate and an adviser to Bohdan Khmelnytsky was elected hetman in 1657 by the Starshyna council. His election caused widespread discontent among other regiments and the Zaporizhian Host, who sent their runners to Moscow with complaints. As a result, new elections were called that same year at which Vyhovsky was reelected at the General Military Council. This election was also confirmed by Moscow's authorities who were informed according to the Pereyaslav treaty. Moscow continued to accept runners from the regions of Cossack Hetmanate completely disregarding the authority of hetman and spreading rumors that in truth Moscow did not support the candidacy of Vyhovsky. Vyhovsky, seeing the situation turning out of his control, went on to extinguish the revolt led by the Zaporozhian Kosh Otaman Yakiv Barabash and Poltava Colonel Martyn Pushkar. In the spring of 1658 Vyhovsky crossed Dnieper and confronted mutineers near Poltava with the help of Tatars. During the battle Pushkar was killed and replaced with a new colonel, while the leaders of the uprising were strictly repressed.
