The Serbs had the initial advantage after their first charge, which significantly damaged the Ottoman wing commanded by Yakub Çelebi. When the knights' charge was finished, light Ottoman cavalry and light infantry counterattacked and the Serbian heavy armor became a disadvantage. In the center, Serbian troops managed to push back Ottoman forces, except for Bayezid's wing, which barely held off the Bosnians commanded by Vlatko Vuković. Vuković thus inflicted disproportionately heavy losses on the Ottomans. The Ottomans, in a ferocious counterattack led by Bayezid, pushed the Serbian forces back and then prevailed later in the day, routing the Serbian infantry. Both flanks still held, with Vuković's Bosnian troops drifting toward the center to compensate for the heavy losses inflicted on the Serbian infantry.
