Thank you for this. I'm sorry to have to add a pessimistic note. Yes, the proclamation that day declared slavery over, but the former slaves were not quite "free." The rest of the proclamation reads:

"[T]he connection heretofore existing between them becomes that between employer and hired labor. The freedmen are advised to remain quietly at their present homes and work for wages. They are informed that they will not be allowed to collect at military posts and that they will not be supported in idleness either there or elsewhere."
