Ashras gave command of his cavalry to Thabit Qutnah, who managed to rout the raiders and drive them to Amul. There the Arabs defeated the Türgesh, although a decisive victory eluded them as Türgesh reinforcements crossed the river and allowed the raiders to escape to safety back over the Oxus.[12][13] At length Ashras got his forces across, linked up with Qatan ibn Qutayba, and began to advance on Bukhara.
