In 1766, the Marathas under Mulhar Rao, who had been awaiting their opportunity, once more crossed the Jamuna and attacked Phaphund, where a Rohilla force under Muhammad Hasan Khan eldest son of Mohsin Khan, was posted. On receipt of this news Hafiz Rahmat advanced from Bareilly to oppose the Marathas. He was joined near Phaphund by Sheikh Kuber, the Rohilla governor of Etawah, and prepared to give battle; but Mulhar Rao refused to risk an engagement and once more retired across the Jamuna. The ambitions Najib-ud-daula had been considerably irritated by the intervention of the Rohillas on behalf of Ahmad Khan Bangladesh in 1762; and though he had been too busily engaged otherwise to pursue his plans of revenge before, he began in 1770 to plot the downfall of Hafiz Rahmat Khan.
