The first town assaulted in Muhammad's Sindh campaign was Debal and upon the orders of al-Hajjaj, he exacted a retribution on Debal by giving no quarter to its residents or priests and destroying its great temple. From Debal, the Arab army then marched northeast taking towns such as Nerun and Sadusan (Sehwan) without fighting. One-fifth of the war booty including slaves were remitted to al-Hajjaj and the Caliph. The conquest of these towns was accomplished with relative ease; however, Dahir's armies being prepared on the other side of the Indus had not yet been confronted. In preparation to meet them, Muhammad returned to Nerun to resupply and receive reinforcements sent by al-Hajjaj. Camped on the east bank of the Indus, Muhammad sent emissaries and bargained with the river Jats and boatmen. Upon securing the aid of Mokah Basayah, "the King of the island of Bet", Muhammad crossed over the river where he was joined by the forces of the Thakore of Bhatta and the western Jats.
