The King went to Khushab, and thence despatched Kutb Khan Banet, Khawas Khan, Haji Khan, Habib Khan, Sarmast Khan, Jalal Khan Jaloi, 'Isa Khan Niazi, Barmazid Gur, and the greater part of his army, in pursuit of the Emperor, towards Multan. He instructed them not to engage the Emperor, but to drive him beyond the borders of the kingdom, and then to return. When they had gone two marches, they heard that the Mughal army had divided into two portions. The Afghan army was in great anxiety, lest, as the force with the King was so small, the Mughals should make forced marches, and attack him. The Afghan army, therefore, also dividing itself into two divisions, the one under Khawas Khan, 'Isa Khan, and others, crossed the river, and marched along the bank of the Jelam towards Multan; and Kutb Khan and the rest remained and marched along the nearer bank of the same stream.
