Taking advantage of the internal conflict and its consequences in Hungary, Stefan Uroš I brought an invasion force to Mačva, and did considerable damage to the city and the province in the spring of 1268.

According to historian Judit Gál, when deciding on an invasion, those could also be taken into account that the Hungarian younger king Stephen entered into an alliance with the Byzantine Empire after the civil war (his daughter Anna was engaged to Andronikos Palaiologos), in addition to Stefan Uroš signed a peace treaty with the Republic of Ragusa in early 1268 to conclude the decade-long war with the Dalmatian maritime republic.

Stephen Csák sent his familiaris Nicholas, son of Mark from Szepes County to inform the royal couple of the victory.

[1] During the battle, a soldier Michael Csák bravely fought and captured two important Serbian barons: an unidentified son-in-law of King Stefan Uroš and a son of the monarch's treasurer in their full armor and with their horses in the sight of Duke Béla of Macsó.

[3] King Béla IV and Queen Maria Laskarina intended to buy the relic from Michael, who thus requested landholdings from the royal couple, instead of an amount of money.
