It's an improbable outcome, but we have AHCs for a reason. I'm not sure what those reasons are, but anyway. It was a common belief in the United States, I believe, that the Canadians(and the Canadiens) would greet the Americans as liberators. How would you make the Canadians (and the Canadiens) support the American mission of removing British control over Canada and instead have American control over Canada (or at least, reparations for the press of American merchants and the lessening of trade restrictions)? Could this turn the tide in the War, or was it doomed anyway? Would any of this be even possible?
