Accordingly, a Maratha army was invited to Delhi for the purpose of first wresting Farrukhabad from Ahmad Khan and of afterwards invading Rohikhand. The united forces of Najib-ud-daula and the Marathas advanced from Delhi; but at Koil Najib-ud-daula fell ill and retraced his steps, leaving his eldest son, Zabita Khan to operate with the Marathas. Zabita Khan however, was by no means disposed to fight against his brother Afghans. The Marathas, knowing this, kept him practically a prisoner in their camp and he requested Hafiz Rahmat Khan to obtain his release. Hafiz Rahmat Khan accordingly opened negotiations with the Marathas for the release of Zabita Khan; but the Maratha leaders demanded as their price the surrender of the jagirs of Etawah and Shikohabad. Hafiz Rahmat Khan was not disposed to agree to those terms, and while negotiations were proceeding for buying off the Marathas Zabita Khan escaped. Several desultory engagements now took place between the Marathas and the Afghan forces. Inayat khan was summoned by his father to Farrukhabad in order that he might be consulted regarding the surrendering of his jagirs. But although Dhunde Khan agreed to give up Shikohabad Inayat Khan refused to surrender Etawah.
