Ten days were spent at Kanauj in preparations for the passage of the Ganges but Akbar, on hearing that Iskandar was preparing to make a stand at Lucknow, crossed the river and, covering the 70 miles between Kanauj and Lucknow in two nights and a day, surprised Iskandar and forced him to flee. The horses of the cavalry were so spent that pursuit was impossible and Iskandar was thus able to join Khān Zamān before Mānikpur, but he, learning that Akbar had occupied Lucknow, raised the siege, retreated with all speed across the Ganges and took refuge in the rough and broken country to the north-east of the Gumti.
