Then, while Humāyūn was making an easy conquest of a defenceless but devastated area, Sher Khān, who had hitherto carefully avoided facing him in the field, set about cutting his communications. He besieged Benares and sent Khavāss Khān, whom he had recalled from Gaur, to Monghyr with instructions to seize the officer whom Humāyūn had left in command of that city.
