Like in so many revolutionary movements, there was
Remember, they were agitating for responsible government, for more democracy, rather than directly for independence. Although there was some republican sentiment.
Note that the GOT responsible government, as a political result of the failed military action. So in some senses the DID win.
And, as funnyhat pointed out, if Britain had to bring troops over to crush the rebellion, which iirc they didnt even bother to do, theyd have done it.
A temporary Patriote military victory (and how would you pull THAT off), MIGHT make things worse when they are inevitably crushed - if Britain views them as treasonous rather than subjects fighting for British rights...
Like in so many revolutionary movements, there was disagreement about the desired end state, especially between the Upper Canada rebellion in 1837, the Lower Canada rebellion in 1837, and the 1838 actions, and between the various stripes of patriotes, chasseurs, hunters, etc. - there were those who wanted something more under the British crown, than the Chateau clique and/or Family Compact (i.e, the seigneurial system), there were those who wanted outright independence, and there were those who were essentially loyal, but thought the military response was overkill, and so helped some of those on the wanted list escape Wetherall et al.
There were also those who were essentially French Canadian nationalists, and those who were Republican "unionists" (in reference to including both upper and lower Canada in an independent state) and almost everything in between - including anticlericalist and antiseigneurial liberals ("les rouges"), all of whom found themselves in alliance at times and at odds at times as well.
It's worth going through the Dictionary of Canadian biography listings - start with Louis-Joseph Papineau (or his father Joseph, for that matter) and William Lyon Mackenzie - and then hit the various links. The overlap with those who took positions on the rebellion losses bill and annexation in 1849, and the burning of Parliament, is very interesting, much less those who were still in public life at the time of Confederation in 1867.
The views of those executed by the British
or transported alone represented probably a half-dozen points of view...
