After a short skirmish Humayun’s army was defeated, and the Afghans ... arrived first at the head of the bridge broke it down, while artillerists and archers seated in boats kept the army under a perfect hail of fire, drowning them in the ocean of destruction. Muhammad Zaman Mirza was overwhelmed by the tempest of death, and Humayun urged his horse into the water and was in dread of drowning, in fact was on the point of drowning, when a water carrier came to his aid and rescued him from that whirlpool of destruction. Then he turned towards Agra. Shir Khan wrote this verse upon that event:— Thou givest sovereignty to Farid the son of Hasan, Thou givest the army of Humayun to the fishes. Although the master (Ustad) has [this second verse]— One thou exaltest and givest him sovereignty, Another thou castest down from his throne to the fishes. This event occurred in the year 946 H. and to commemorate it the following chronogram was written: Salamat az sar-i ab-i Nil raft. And Shir Khan after the victory turned back, and came to Bangala, and after fighting several engagements put to death Jahangir Quli Beg with all his following. In that country he read the khutba in his own name, and assumed the title of Shir Shah, and in the following year proceeded with a vast army intending to capture Agra.
