Better Than Slavery? Contraband Camps and Abuses at the Hands of Liberators (mp3)
The beauty (to me at least) of these WBTS threads is that it inspires us to look into our history and seek the truth. We can evaluate the facts and still come to differing conclusions. Or we can make up "facts" whole-cloth and disrespect the truth.
What I found is at variance with your assertion about "internment camps" for Freedmen. Here is a narrative which describes the events (yea, I know - opinions vary) and here is the preliminary report of the Freedmen's Inquiry Commission, along with a brief final report here.
There was no deliberate and malevolent "lock up the darkies" internment camps. There was a certain amount of disorder and "seat of the pants" scrambling which took place as the union attempted to care for the newly freed slaves. I suppose that a dark heart can find darkness in the events but reasonable people see it for what it was.
