The Battle of Malyi Utlyuh was fought on 31 October 1655 between the armies of the deposed Khan Mehmed IV Giray and forces loyal to the Khan of Crimea Islam III Giray. The rebels defeated Mirza Appak's loyalist army near Kyzyl-yar, enabling the rebels to besiege the city.
After the Battle of Trudove, Jerzy Wisniewski's Polish mercenaries and Mehmed IV Giray's rebels besieged Kyzyl-yar Fortress. Mirza Appak, Mirza Divey, and Ahmed-pasha's armies, loyal to Islam III Giray, marched to Kyzyl-yar to lift the siege, but Wisniewski persuaded Ahmed-pasha to join Mehmed IV's cause, while Mirza Divey and his army entered the garrison at Kyzyl-yar. This left Mirza Appak alone to face the rebels, and, after Mirza Appak refused to join the uprising, the combined rebel armies attacked his force. In the ensuing battle on the Malyi Utlyukh River, the battle-hardened Polish and Tatar mercenaries of Wisniewski's army easily defeated the unarmored Tatar horsemen, especially once they became bogged down at the river crossing. Mirza Appak's army was destroyed, and Wisniewski and his allies returned to the siege of Kyzyl-yar.
