v4.c17.47

Mahābat Khān, the most capable soldier in the imperial forces, had for some years been governor of Kābul and had kept order in that difficult province. He was now summoned to take command, and after some demur, owing to his suspicions of Āsaf Khān whom he rightly believed to be his enemy, was persuaded to accept the post by the formal appointment of Āsaf Khān to Bengal. Shāh Jahān was unable to capture the fort of Āgra with its treasure, but plundered the city which had no walls. He then marched north to meet his father's army, and though he was successful in detaching 'Abdullah Khān, who came over with a large force during the battle, he was decisively beaten at Bilochpur (March, 1623), and lost Rājā Bikramājīt, one of his best commanders.
