I've been reading John Eisenhower's Agent of Destiny: The Life and Times of General Winfield Scott, and one of the things it talks about was Scott's role in defusing American involvement for the Rebellions of 1837. American personal involvement was relatively low, mostly cash and supplies with a scattering of troops, but the assumed death of an American citizen inflamed much of the Western states (in the 1830's that would be Ohio and such). Most of the army was in the South fighting and removing Natives from their land, and not in the position to either get personnel away from the semi-Civil War, or to fight the British/Canadian forces. Still many saw a third war with the British Empire as inevitable.
Is it possible that events could have deteriorated to the point where another war would start? Could America win and force Britain to either cede or let Canada fall into independence?
