Soon after the Battles of Lexington and Concord, the fledgling United Colonies invaded the British Province of Quebec. Despite the heroic efforts of men like General Richard Montgomery, Colonel Benedict Arnold, and Colonel Daniel Morgan, the 1775-76 invasion failed at the granite walls of Quebec City. A second, lesser known invasion, led by George Rogers Clark succeeded wonderfully a few years later, resulting in the largest capture of British territory during the American Revolution.
