By distinct difficulties, I was making a pointed reminder of the fact that Canada was under complete British occupation, you know? I kinda doubt a Georgian or South Carolinian regiment would have had much luck in 1780, either.
Not to mention that it is much harder and more dangerous to travel from Canada to the US in 1777 than from Kentucky to Tennesee or points south or east in 1860. Not exactly comparable situations.
Being under complete British occupation doesn't preclude traveling southward - or northward in the case of the Georgia and South Carolina Lines.
And more dangerous than in 1862-1864 (when most of the Confederate Kentucky regiments were raised - only a few were present in 1861), though?
Besides, all you asked for was "how much if at all did the Canadiens believe it"; clearly, some did enough to risk their lives. Wheather enough did so enough to risk a lengthy and hazardous journey through a war zone to join the Continental Army at a time when it was not doing so hot is irrelevant to the question you asked. Now you're just nitpicking and moving goalposts.
No, I'm pointing out that we have "a few" in all of two regiments that may or may not have ever reached full strength (to the extent any Continental regiment ever did, since expecting them to do better than say the Maryland Line is unfair). That's something as opposed to "total hostility", but it's not a particularly impressive turn out, either.
So my point is, and the reason for the original question (and follow up questions), is 'did Canadians
in general believe this?"
We have, from the wiki article, 300+ for Livingston, 250+ for Hazen. Out of an authorizes strength of 1000+.
And this with the opportunity for them to join from September (when Livingston starts recruiting) to June (the American retreat) - Hazen managing 250 in February-April for a regiment authorized in January.
If it's "moving the goal posts" to find there being less than a regiment raised as a sign of a lack of enthusiasm, then I wonder how you take it by comparison to the success (such as it was) of Continental recruiting efforts elsewhere.
