On 22 June, between eleven and twelve o'clock, Erdődy and Auersperg's forces attacked Ottoman positions with the army of Erdödy in front, consisting of Croatian hussars and infantry. The first assault was repulsed by Ottoman cavalry. Then the soldiers of Colonel Auersperg joined the attack followed by Eggenberg's and other commanders' men, forcing the Ottomans back towards the Kupa River. The army of Hasan Pasha was driven into a corner between the rivers Odra and the Kupa, with the bridge across the Kupa taken by soldiers from Karlovac. The Sisak garrison led by Blaž Đurak attacked the remaining Ottoman forces that were besieging Sisak. Caught in the middle between two Christian army flanks, the Ottomans panicked and started a chaotic retreat, trying to swim across the Kupa River and reach their camp. The bulk of the army, with most of the commanders, were either slaughtered or drowned in the river.
