The occupation, however, was merely nominal at first; the zamindars refused to pay revenue to Inayat Khan and, secure in their mud forts set his authority at defiance. Strong reinforcements were sent to the Rohillas, including some artillery, under Sheikh Kuber and Mullah Baz Khan, and many of the smaller forts were levelled to the grounds; but in their ravine fortresses the zamindars of Kamait in the trans-Yamuna tract still resisted the authority of Inayat Khan. Hafiz Rahmat and Inayat Khan then came in person to Etawah and operations were vigorously pressed against the refractory zamindars. Ultimately an annual tribute was agreed to by the latter. Hafiz Rahmat then departed to Bareilly, and Rohilla garrisons were established at convenient places in the district. Meanwhile, a new minister arose at Delhi called Najib Khan, better known as Najib-ud-daula, Amir-ul-umra, Shuja-ud-daula succeeded Safdar Jang as Nawab Wazir and occupied most of the Bangash possessions as far as Aligarh, with the exception of those granted by the Durrani to the Rohillas after he battle of Pandit. But the wazir's hostility to the Farrukhabad Afghans had not abated one jot, and in 1762 he persuaded Najib-ud-daula to join him in an attack on Farrukhabad. The attack was beaten off by the aid of Hafiz Rahmat Khan and matters once more settled down peacefully.
