Frederick Douglass was no more an authority about the war than anyone else.

As a newspaper man and a regular public speaker on political issues it is highly likely that he was better versed in the events of the war than your average citizen. Same goes for Horace Greeley who corroborated Douglass' comments about the black confederates.

Frederick Douglass had no better information on what was going on in the war than did other people. Horace Greeley was a crackpot.
