According to Chambers' description of the battle, the Silesian cavalry initiated combat with the vanguard (mangudai) of the Mongol army. After the Silesians were repelled, the cavalry of Greater Poland, led by Sulisław, and the cavalry of Opole then attacked the Mongols. The Mongol vanguard retreated, inducing the allied cavalry to pursue, thereby separating them from the Polish infantry. Although the mangudai fled, Mongol light cavalry flanked the Polish forces. A smokescreen was used to hide the Mongol movements and confuse the Europeans. While the Mongol light cavalry attacked from the flanks and the heavy cavalry attacked from the front, Mongol archers peppered the Polish forces with arrows.
