Williams had, I submit, a dual purpose - that blacks served widely and willingly in the rebel army and that their service was valued and respected by white Southerners of the period. The first half has an element of truth in it. The second is plain ridiculous.
Sorry, but I see absolutely nothing in the article that suggests an argument on William’s part that “blacks served widely and willingly”; Mr Williams simply cites historical records and the writings of Charles Wesley, black historian, that certain numbers of negroes/blacks served willingly in the Confederate army.
Not true. There are many instances in the diaries of Southern soldiers and officers of Confederates giving "huzzahs' and 3 cheers for their fellow black soldiers, as they were either on their way to, or returning from, a battle.
Your anti-southern bias and hatred is showing, and it is not attractive.
