It was the official policy of the Confederate States that white officers of U.S. colored troops were not to be afforded the same treatment and consideration as officers of U.S. white troops.

Reference--"A Digest of Military and Naval Laws of the Confederate States," Part XVIII, Para. 511: That every white person, being a commissioned officer, or acting as such, who, during the present war, shall command negroes or mulattoes in arms against the Confederate States, or who shall arm, train, organize, or prepare negroes or mulattoes for military service against the Confederate States, or who shall voluntarily aid negroes or mulattoes in any military enterprise, attack, or conflict in such service, shall be deemed as inciting servile insurrection, and shall, if captured, be put to death, or be otherwise punished, at the discretion of the court.
