The Ottoman army entered Transylvania on October 9, near Kelnek (Câlnic), led by Ali Koca Bey. The Akıncıs attacked a few villages, homesteads, and market towns, taking a number of Hungarians, Vlachs, and Saxons captive. On October 13, Koca Bey set up his camp in the Breadfield (Kenyérmező), near Zsibót. Koca Bey was obliged into the campaign by the insistence of Basarab cel Tânăr, a Wallachian prince, who himself brought 1,000–2,000 infantry to the cause.

The battle commenced in the afternoon. Stephen V Báthory, the Voivode of Transylvania, fell from his horse and the Ottomans nearly captured him, but a nobleman called Antal Nagy whisked the voivode away. Having joined battle, the Ottomans were in ascendancy early on, but Kinizsi charged against the Turks with the Hungarian heavy cavalry and 900 Serbs under Jakšić assisted by "numerous courtiers of the king". Ali Bey was forced to retreat. Kinizsi moved laterally to vigorously smash the Turkish center and before long Isa Bey also withdrew. The few Turks who survived the massacre fled into the mountains, where the majority were killed by the local men. The hero of the battle was Pál Kinizsi, the legendary Hungarian general and a man of Herculean strength in the service of Matthias Corvinus' Black Army of Hungary.
