Soooooooo you're not counting the second independent republic in the Americas after us?
That was Haiti and they fought for their nation’s independence.
Correct. And there was bloodshed to end slavery. See your post above.
It's fair to say there was bloodshed over slavery all over the Americas in fact, whether there was an official 'war' or not. Just yesterday was the anniversary of the execution of Nat Turner. And for that matter, John Brown leading another slave revolt was a major trigger of the Civil War too, before the War happened.
