Governor of Upper Canada. A small steamboat owned by the American invaders, with which they kept up communications with their own side of the river, and which was laden with arms and ammunition for the insurgents, was cut adrift from her moorings on the night of December 29th, set on fire, and left to sweep over the cataract. The affair led to a great deal of diplomatic correspondence between the American and British Governments; but the preceding violation of Canadian soil by a body of adventurers precluded the Cabinet of Washington from making any serious demands on that of London. Ultimately, in the course of 1838, the President (Mr. Van Buren) issued a proclamation calling on all persons engaged in schemes for invading Canada to desist from the same, on pain of such punishments as the law attached to the offence. This put an end to the difficulty so far as the two countries were concerned; but the insurrection was not yet entirely suppressed. Although the worst disaffection was in Lower Canada, both provinces were disturbed by movements of a disloyal nature. Upper Canada was excited by the fiery appeals of a Scotsman named William Lyon Mackenzie; Lower Canada by the incitements of Louis Joseph Papineau, one of the disaffected French provincials. The two divisions of the colony, however, were jealous of each other, and this hampered what might otherwise have been a more dangerous rising. The Radical party in England supported the cause of the malcontents, and insisted on the necessity of at once redressing all grievances. The Government of Lord Melbourne maintained that the rebellion must be first suppressed; and undoubtedly that was the only course consistent with Imperial authority. In the autumn of 1837, a small party of English troops was beaten at St. Denis; but another detachment was successful against the rebels, and the garrisons of the various cities, though extremely small, held their own against the rising tide of insurrection. Aided by the Royalists, the Government force under Sir John Colborne inflicted some severe blows on the enemy; yet the movement continued throughout the greater part of 1838. On the 16th of January in that year, however, the Earl of Durham had been appointed Governor-General of the five British colonies of North America, and Lord High Commissioner for the adjustment of the affairs of Canada. The liberal policy thus inaugurated, and the victories obtained over the rebels by Sir John Colborne, Sir Francis Head, and others, brought the revolt to an end before the close of the year, and the colony soon afterwards entered on a future of prosperity.
