Yeah, my ancestor was actually a British subject, but fought for the Confederacy because he was living in Georgia when the war started. At the end of the war he and his troops refused to surrender and they fled into Mexico. He went from there to London, and then from London to British Columbia. Technically he could have been hanged if the Union captured him, but that never happened. Needless to say, he didn’t give a rip about slavery.
What a family saga!
