There is absolutely no evidence to show that either Thomas Jackson or Jefferson Davis ever freed a single slave. Both were meticulous men who kept careful records. If they had ever freed any of their slaves then there would be a paper trail. There is none. Both men have a number of detailed biographies available, including ones written by their wives. None of these biographies say that either man ever freed a slave. Your claim is false.
Now, prove me wrong.
I believe the ball is in YOUR corner.
