In March 1772 Francis finally left the war office, and in July of the same year he left England for a tour through France, Germany and Italy, which lasted until the following December. On his return he was contemplating emigration to New England, when in June 1773 Lord North, on the recommendation of Lord Barrington, appointed him a member of the newly constituted supreme council of Bengal at a salary of L10,000 per annum. Along with his colleagues Monson and Clavering he reached Calcutta in October 1774, and a long struggle with Warren Hastings, the governor-general, immediately began. These three, actuated probably by petty personal motives, combined to form a majority of the council in harassing opposition to the governor-general's policy; and they even accused him of corruption, mainly on the evidence of Nuncomar. The death of Monson in 1776, and of Clavering in the following year, made Hastings again supreme in the council. But a dispute with Francis, more than usually embittered, led in August 1780 to a minute being delivered to the council board by Hastings, in which he stated that "he judged of the public conduct of Mr Francis by his experience of his private, which he had found to be void of truth and honour." A duel was the consequence, in which Francis received a dangerous wound (see HASTINGS, WARREN). Though his recovery was rapid and complete, he did not choose to prolong his stay abroad. He arrived in England in October 1781, and was received with little favour.
