The Chachnāma (Fatḥnāma-yi Sind) 30: The answer of Siharas.

30

Siharas said to Matta, "Chach was a great king, and had an extensive territory under his sway. As he is dead, I will bring his possessions under my own rule, if I take them. They will form a great addition to my kingdom, and I will appoint you over one of their divisions." Siharas then sent his brother Barhas, son of Kasais. The son of the daughter of the great Chach, who ruled over Kashmir and Ramal, also agreed to join him, and they proceeded with their armies till they reached the banks of the Hasi, where they encamped. The agents and officers of Chandar, who were still in the fort of Deo, fled. The invaders took the place, and advanced on their journey till they arrived at Band Kahuya, where they halted for one month, and performed the worship of Budh. They sent a messenger with a letter to Chandar to induce him to come, make his submission, and sue for protection.
