By those words of false alloy, having put Sl. Mas`ūd Mīrzā off his guard, Khusrau Shāh and Bāī-sunghar Mīrzā moved light out of Chaghānīān, surrounded Ḥiṣār and, at beat of morning-drum, took possession of it. Sl. Mas`ūd Mīrzā was in Daulat Sarāī, a house his father had built in the suburbs. Not being able to get into the fort, he drew off towards Khutlān with Shaikh `Abu'l-lāh _Barlās_, parted from him half-way, crossed the river at the Aūbāj ferry and betook himself to Sl. Ḥusain Mīrzā. Khusrau Shāh, having taken Ḥiṣār, set Bāī-sunghar [Sidenote: Fol. 57.] Mīrzā on the throne, gave Khutlān to his own younger brother, Walī and rode a few days later, to lay siege to Balkh where, with many of his father's begs, was Ibrāhīm Ḥusain Mīrzā (_Bāī-qarā_). He sent Naẕar _Bahādur_, his chief retainer, on in advance with 3 or 400 men to near Balkh, and himself taking Bāī-sunghar Mīrzā with him, followed and laid the siege. Walī he sent off with a large force to besiege Shabarghān and raid and ravage thereabouts. Walī, for his part, not being able to lay close siege, sent his men off to plunder the clans and hordes of the Zardak Chūl, and they took him back over 100,000 sheep and some 3000 camels. He then came, plundering the Sān-chīrīk country on his way, and raiding and making captive the clans fortified in the hills, to join Khusrau Shāh before Balkh. One day during the siege, Khusrau Shāh sent the Naẕar _Bahādur_ already mentioned, to destroy the water-channels[427] of [Sidenote: Fol. 57b.] Balkh. Out on him sallied Tīngrī-bīrdī _Samānchī_,[428] Sl. Ḥusain Mīrzā's favourite beg, with 70 or 80 men, struck him down, cut off his head, carried it off, and went back into the fort. A very bold sally, and he did a striking deed. (_g. Affairs of Sl. Ḥusain Mīrzā and Badī`u'z-zamān Mīrzā._) This same year, Sl. Ḥusain Mīrzā led his army out to Bast and there encamped,[429] for the purpose of putting down Ẕū'n-nūn _Arghūn_ and his son, Shāh Shujā`, because they had become Badī`u'z-zamān Mīrzā's retainers, had given him a daughter of Ẕū'n-nūn in marriage and taken up a position hostile to himself. No corn for his army coming in from any quarter, it had begun to be distressed with hunger when the sub-governor of Bast surrendered. By help of the stores of Bast, the Mīrzā got back to Khurāsān.
