The treaty, signed in Prague on 9 June 1598, made Wallachia a vassal state; in exchange, the emperor undertook to cover the cost of providing 5.000 mercenaries to the principality.

Another Wallachian army corps, composed of 6,000 warriors from Oltenia, led by Radu Buzescu Ban Udrea and Serbian hajduk commander Starina Novak, crossed the Transylvanian Alps through Turnu Roşu Pass.

Many of them did not fight, however, preferring instead to remain in the camp and protect the women and children of the boyars who had joined them in this campaign out of the fear of possible Tatar attacks in Wallachia.

The Wallachians gained the upper hand at the beginning of the battle, but were pushed back quickly by the charge of the Hungarian Hussars.

What is more he also invited some Székelys and other Transylvanian Hungarians to assist in the administration of Wallachia, where he wished to transplant Transylvania's far more advanced feudal system.
