I did notice, but I didn't want to mention it because I've kind of made a mess of the names of TTL's Civil War. While I would like it to be known as the Slaveholders' Rebellion or something like that, within the text I've consistently called it the Civil War. And, given that that was the most common way to call the conflict IOTL too, from the very start, I think having the name stick would be unavoidable. My idea was that maybe the entire war is referred to as the Civil War, but the movement against Breckinridge which resulted in the coup and then the war continuing
is called the Slaveholders' Rebellion. Likewise, an idea that I had was that the
Stars and Bars would be associated with Breckinridge and his government, and the
Battle Flag with the Junta.
