63.12.1

In the course of the same year, Dawood Khan, the son of Sooliman Kirany, ruler of Bengal, took up arms. Moonyim Khan, Khan Khanan, was sent against him, and after several actions compelled him to sign a treaty; but the King, dissatisfied with the instrument, committed the management of Bengal to Raja Todur Mul, and sent him with orders either to expel Dawood Khan or compel him to pay tribute. Dawood Khan, being threatened at the time with a civil war by Lody Khan Afghan, who discovered an inclination to usurp his authority, consented to pay tribute. Having shortly after seized Lody Khan, he put him to death; and being relieved from that domestic danger, he broke the treaty with Moonyim Khan, and attacked him at the confluence of the Soane and the Ganges, where Dawood Khan was defeated, and having lost his fleet of boats, he fled. Moonyim Khan instantly crossed the Soane, and laid siege to Patna.
