Firishta's History (Gulshan-i Ibrāhīmī) 62.4.6

62.4.6

When the news of Tartar Khan's defeat reached Sikundur Shah Soor, he exacted an oath of fidelity from his officers, and marched with eighty thousand horse, a large train of artillery, and a number of elephants, towards Punjab. Beiram Khan advanced as far as the fort of Nowshera, and prepared it for a siege by laying in provisions. Sikundur Shah Soor encamped before the place, and Beiram Khan sent continual letters to Lahore, to hasten the march of Hoomayoon, who soon after joined. Beiram Khan in the interim made repeated sallies from the city, and greatly distressed the enemy in his camp. On the last day of Rujub, while the Prince Akbur was visiting the pickets of the camp, the Afghans drew up their forces and offered battle.
