Firishta's History (Gulshan-i Ibrāhīmī) 8.3.2

8.3.2

Musaood continued his march from Herat to Nyshapoor, and from thence to Toos. At Toos, he was attacked by another horde of Suljooks, which he defeated with great slaughter; but having received intelligence that the inhabitants of Badwird had given up their forts to the Suljooks in that quarter, he marched immediately against them, retook the forts, and cleared that country of the enemy. He now returned to Nyshapoor, where he spent the winter. In the spring of the year 431 he returned to Badwird, which had been again invaded in his absence by Toghrul Beg, who fled upon the Sooltan's approach towards Badwird and Tedzen. Musaood returned by the route of Suruksh, whose inhabitants refused to pay the revenue. Some of their chiefs being punished, the rest became more tractable, and after their submission the King continued his march to Dundunaken. At this place the Suljooks, collecting their forces, surrounded the King's army on the 8th Rumzan, A. H. 431, and secured the passes on all sides. Musaood drew up his army in order of battle, to induce the enemy to come to action, which they by no means declined, advancing on all sides with barbarous shouts, and with great impetuosity. This uncommon method of charging discouraged the Ghiznevide troops; and, whether through fear or perfidy, several generals, in the commencement of the battle, rode off with their whole squadrons, and joined the enemy.
