I gave you a figure of 65,000, with 13,00 of which 13,000 of these black men "saw the elephant." I even posted the website. If you dispute those, feel free to contact Dr. Williams and question his research. For myself, until these numbers are proved wrong I'll continue to site them as my source.
To say these men had no effect on a battle or the war is just plain wrong. I am sure that whatever number they served in they did have an effect, regardless if it was hauling ammo or caring for the wounded. On the other side of the coin if you wish to promote the contributions of the USCT as releasing white men to battle, then the Southern blacks did the same thing.
Your whole entire argument is nothing more than smoke and mirrors.
