Here's a rather fascinating article about a black man who is a member of the Sons of Confederate Veterans. Apparently his grandfather - whom he knew - was a slave who went to war with the sons of his owner. Eventually the grandfather became a soldier himself, fighting under (of all people) General Nathan Bedford Forrest. He would serve out the war as a chaplain, conducting services for soldiers on both sides of the war. When he died in 1934, a Confederate flag draped his coffin.
It's a fascinating story that leaves me with a ton of questions I'd like to ask this guy. Starting with this: wasn't it illegal for black men to fight in the Confederate army? How did he get away with fighting for the South? Especially under the notoriously racist Forrest?
Anyway, black Confederate soldiers deserve more study. What were their motivations? How did they get around the rules? Did they confuse the crap out of Union soldiers? And what effect did they have overall?
