This has absolutely nothing to do with the Civil War but I got a chuckle from the quote.
"My mental faculties remained in suspended animation while I obeyed the orders of the higher-ups. This is typical with everyone in the military."
Smedley Butler

My grandfather fought under Butler in Haiti while the first world war was on. Which quite frankly colored his perception of blacks. However one must see him in the context of his time and place.
