but before setting out he appointed his guest to the governorship of those parts of India (the whole of the Punjab) which belonged to him, and in this capacity Mirza Haidar resided for over a year at Lahore, "collecting taxes, suppressing revolt, protecting the frontiers, and establishing Islam." It was shortly after Kamran's return to the Punjab, (1538) that Humayun had sustained a severe defeat in Bengal at the hands of Shir Shah Sur, the Afghan leader, who was now advancing towards Agra by the left bank of the Ganges. A large part of Humayun's army having accompanied him to Bengal, he made an appeal to Kamran and his other brothers to send assistance to Agra, while he himself hurried northward. Kamran, after some hesitation, consented, and moved first to Delhi and then to Agra, with an army of 20,000 men, and in company with our author. Here dissensions took place among the brothers; Kamran repented of his decision to support the Emperor, and putting forward bad health as a reason, determined to return to Lahore, while Shir Shah was yet on the far side of the Ganges. He endeavoured to persuade Mirza Haidar to return with him, but the Mirza declined on patriotic grounds, and from that time forward (1539) became an adherent of Humayun, who treated him with great honour and called him "brother, after the Moghul fashion." The disastrous battle of Kanauj soon followed.
