Did you know Forrest quit the KKK because he thought it was getting to Violent and wasn't helping the post civil war south. For a man like Forrenst to quit the KKK due to the level of violence says something. As far as Fort Pillow , the North was warned by the Confed. what would happen to Colored union soilders and thier officers captured in battle.
As I said, there are 2 sides to the Forrest myth and the truth lies in between...
