The British Calcutta Council condemned the Treaty of Surat, sending Colonel Upton to Pune to annul it and make a new treaty with the regency. The Treaty of Purandhar (1 March 1776) annulled that of Surat, Raghunathrao was pensioned and his cause abandoned, but the revenues of Salsette and Broach districts were retained by the British. The Bombay government rejected this new treaty and gave refuge to Raghunathrao. In 1777, Nana Phadnavis violated his treaty with the Calcutta Council by granting the French a port on the West coast. The English retaliated by sending a force towards Pune.
