The bishop and the priests, from the outset, were quite alive to the gravity of the situation. They could not forget that the delegates to the continental congress, who were now appealing to French Canada to join the rebellious colonists, had only a few weeks before issued an address to the people of England in which they expressed their astonishment that the British parliament should have established in Canada "a religion that had deluged their land in blood and dispersed impiety, bigotry, persecution, murder, and rebellion through every part of the world." Almost simultaneously with the capture of the forts on Lake Champlain, Bishop Briand issued a _mandement_ in which he dwelt with emphasis on the great benefits which the people of French Canada had already derived from the British connection and called upon them all to unite in the defence of their province. No doubt can exist that these opinions had much effect at a time when Carleton had reason to doubt even the loyalty of the English population, some of whom were notoriously in league with the rebels across the frontier, and gave material aid to the invaders as soon as they occupied Montreal. It was assuredly the influence of the French clergy that rendered entirely ineffectual the mission of Chase, Franklin, and the Carrolls of Maryland--one of whom became the first Roman Catholic archbishop of the United States--who were instructed by congress to offer every possible inducement to the Roman Catholic subjects of England in Canada to join the revolutionary movement.
