They were survivors, they refused to fight against their own people but had no problem killing Indians.
The Traitors were the ones who fought their own people. But I think when they became treasonist is after their capture. My GGG Grandpa was a conscripted Unionist. From the gitgo he did not want to foght for the confederacy, first good oportunity he deserted and enlisted in the Unon. That isn't what I deem a traitor.
Traitors were spouting off Confederates Rights and etc. but when the chips were down the turned blue.
