@Coctaanatis I know this already, and I also know that accusing somebody of being a "Unionist" was all it took for the Confederacy to seize their property and possibly hang them.
The Confederacy also persecuted Quakers and recent immigrants.
The Tennessee Union 13th Calvary was feared by the Confederacy,. 30,000 Tennesseeans joined the Union Army. Something similar happened in North Carolina.
