The Chachnāma (Fatḥnāma-yi Sind) 13: Chach proceeds to the fort of Askalanda.

13

When Chach was informed that the enemy had gone to Askalanda, he placed one of his officers in charge of the fort (of Pabiya) and proceeded to that city. He pitched his tents in its vicinity. There was a great and brave man in the fort of Askalanda, who was in the interest of Chach, and had influence over the people in the fort. All the chief inhabitants always took his advice and never acted contrary to his opinion. Chach sent a man to him and promised to make him governor of that fort. He also ordered a farman to be prepared, granting him the governorship of the fort, on the condition that he would kill Chatera, the chief (malik) of Pabiya, or take him prisoner. Pabiya was also to be made over to him. He agreed to these terms and conditions. He sent his son to Chach, and by occasionally visiting Chatera, gained his confidence, so that he was never prevented from going into his Court either by day or by night. When he found an opportunity, he suddenly killed Chatera and sent his head to Chach. Rai Chach showed him great favour and honour, granted him a reward in token of his pleasure, and made him the independent chief of that fort. The great and noble men of the city attended on him, and made him presents. He treated them all with honour and respect, and kept them faithful to their allegiance. Chach gave him some prohibitions and admonitions, so that he continued faithful in obedience and never disobeyed his orders.
