I have seen some of those numbers, but I don't have time now to research for you.
I think "Southern Wealth and Northern Profits" has some data on that.
It seems that there was quite a bit of "unloading of slaves" from North to South. The high activity level of the "slave pens" in Washington, D. C. being the center of activity. Richmond also saw a large population of slaves moving from North to South.
If I come across more specific data over the weekend, I will let you know.
Those in the North who were involved in pro slavery were
DEMOCRATS!!!!!!!
The Republicans should make a big political issue out of this.
Thanks. It would also be interesting to know whether this trade increased or decreased over time as slavery became more of a "moral" issue over time with more northerners.
IOW, were more slaves sold rather than freed from the first northern states to outlaw slaves than with the later ones?
