The British didn't want New England in 1837, nor did New England want to leave the USA, let alone rejoin the British Empire.
I'm going to call ASB on this one
I thought as much, just wanted to try it out.
Is there any chance post 1777?
Although I must add
It doesn't have to be in 1837.
Does it need to be all of New England? Ethan Allen Attempted to sell Vermont to the British while it was the Republic of Vermont.
NEVER!!!! That would create horrid borders!
I don't know lets be inventive and call it Dominion of Canada.
