Here’s Emmanuel Dabney, an interpretive historian and ranger at the Petersburg National Battlefield Park speaking on the Freedmen’s Bureau. This was at the 2015 Emerging Civil War Symposium. The video’s description says, “Emmanuel Dabney talked about the extensive records of the Freedmen’s Bureau and what they reveal about the lives of former slaves. He also described how the bureau issued food and clothing, operated hospitals and temporary, camps, helped locate lost family members, and provided education and legal services.”
I think he does a really good job with this.
