A lost-cause myth that cannot stand up to the facts. Here's a review of the evidence on the subject.

The most obvious fact is that the CSA congress finally agreed to black soldiers to be enlisted only on March 13, 1865. The Yankees were quite literally at the gates of Richmond, and the law allowing black soldiers was passed only after the personal plea of RE Lee.
Revealingly, Lee requested that black slave soldiers be freed on enlistment. Even with Lee's request and the obvious desperate nature of the situation, the CSA Congress could not bring themeselves to free even blacks who fought for them. They passed the law without such provision.
