152.2.4

After some time, Sultan Shah, Jalal-ud-Din, Mahmud, son of I-yal-Arsalan, Khwarazm Shah, was ousted by his brother, Takish, Khwarazm Shah, and presented himself at the Court of Sultan Ghiyas-ud-Din. After a time he became seditious, as has been previously recorded, and departed for Khita, and from thence brought aid, and took Marw, and began to ravage the frontier districts of the territories of Ghur, and commenced harrying and plundering them, until, in the year 588 H., Sultan Ghiyas-ud-Din commanded, so that Sultan Mu’izz-ud-Din from Ghaznin, Malik Shams-ud-Din of Bamian, and Malik Taj-ud-Din-i-Harab, from Sijistan, with their forces, assembled at Rudbar of Marw, and they came and confronted the forces of Sultan Shah, who, with his troops, marched out of Marw, and proceeded up [the river]; and, in opposing the Sultan, used to make irregular and sudden attacks, and to continually harass the foragers of the Sultan’s army. For a period of six months this harassing warfare went on ; and the two armies continued in proximity to each other until Sultan Mu'izz-ud-Din commanded that a ferry over the river Murgh-ab should be sought for, and he crossed it [with his own forces], and the other troops crossed over after him ; and Sultan Shah was defeated and put to the rout.
