During the battle, the Seljuk Turks mount several attacks on the formations, but all are repulsed. The Byzantine cavalry makes two counterattacks; the first is unsuccessful. But a second attack, led by Nikephoros Bryennios (the Younger), breaks the Seljuk forces, who then turn to flight. The following day Malik Shah again attacks, his army completely surrounding the Byzantines from all sides. The Seljuk Turks are once more repulsed, with many losses. Alexios claims the victory, and Malik Shah is forced to accept a peace treaty, in which he promises to respect the frontiers of the Byzantine Empire.[28][29]
