The battle began by an attack of Moldavian infantry and Tatar–Cossack cavalrymen. From the beginning, the Moldavians, Tatars and Cossacks were driven back by the Wallachian military forces and Lithuanian defenders. Subsequently, both armies advanced to meet in a marshland, where a great melee began. Wallachians, Polish-Lithuanians, Seimeni Serb and Hungarian mercenaries destroyed the entire force of Cossacks and Tatars, with their swords and bayonets; the Moldavians, alongside the German and Austrian mercenaries, retreated a kilometer to prepare for the attacks. They resisted a series of attacks by the Wallachian-led combined troops, until finally the Wallachians bombarded their positions. The German and Austrian mercenaries were all killed during the bombardment. 1,000 Moldavians, 4,000 Cossacks and 1,000 Tatars were taken as prisoners, and mistreated by Wallachians. Almost half of them perished in captivity or were sold as slaves, including Ecaterina Cercheza, the wife of Vasile Lupu.[2]
The battle was a Wallachian decisive victory, resulting in the ousting of the Moldavian Prince and his replacement with Gheorghe Ștefan. There was a brief Wallachian occupation of Iași, and a siege of Suceava (where Tymofiy was killed).
