What was the reason for the fight Douglas found himself in and what happened to him physically?

If you're talking about Frederick Douglass, than this would be accurate. Douglass got into the fight because he was angry that he was being treated like an animal and he didn't want to be anymore. Though he did attack Covey, Covey never whipped or hurt Douglass again. Basically, nothing happened to him physically, other than maybe a few scratches here and there.
