Oh probably because I have never seen a shred of evidence to support your crazy claim that Forrest's cavalry was even 2/10 of a percent black, much less 20%.
in point of fact, you do NOT WANT to KNOW (& fail to seek) the UNcomfortable TRUTH, as the TRUTH "guts" the unionist/lunatic PROPAGANDA spread about by you & other unionists here about the southland's struggle for LIBERTY.
did you ever bother to read BLACKS IN BLUE & GRAY??? NO??? i thought NOT.
to quote the old cliche, "there are NONE blinder than those who will NOT SEE".
