212.3.6

Alla-ood-Deen, the son of Bheilole Padshah, having reached the court, experienced the most honourable reception from Bahadur Shah, and his son Tartar Khan became enrolled among the nobles of the state. So confident was Bahadur Shah of success, that he already began to allot to his officers the different districts of Dehly, before he had even marched his army for its subjection. On the following year a sum of three crores of rupees was furnished to Imad-ool-Moolk, the governor of Runtunbhore, to provide Tartar Khan with a force of forty thousand men; and this prince opened the campaign by reducing Byana, a fortress near Agra. Hoomayoon instantly deputed his brother, Hindal Mirza, to keep Tartar Khan in check till he could come in person; but the Mogul troops had scarcely arrived within a few miles of Tartar Khan’s camp at Byana, before the boasting but dastardly Afghans, of which his army was composed, deserted him, leaving him with a force considerably short of twelve thousand men. Tartar Khan, ashamed of the defection of his countrymen (particularly after assuring Bahadur Shah of his confidence in their attachment), refused to retreat before the superior force of Hindal Mirza, but resolved to meet his fate, whatever might be the result. The two armies being drawn out advanced slowly to the attack. Tartar Khan made the first charge, with a few confidential retainers, on the centre of the Dehly line, but his troops were defeated, and he fell covered with wounds.
