Shawn,
Interesting discussion you've sparked here, but I was starting to wonder if all of it was helpful in locating songs about slave revolts. Thought I'd jump in with the only story-song I can think of on a similar topic. The problem is, I don't know its origins and have no idea if it came from a black or white tradition or, for that matter, if it's a recently penned thing.
The only version I've ever heard of it is by Willie Nelson and it's called Blackjack County Chain. I didn't check if it's in Cowpie, but if it's not, I could give you the words for it if you'd like.
cheers ddw
