Don't you think that's kind of a lazy posting?
How do I know these are white men?
How do I know they were connected with any Indian units?
Finally, what's your point? That you found three (3) possible whites in Confederate Indian units after the Spring of 1862, so that justifies a claim of thousands of Black Confederates charging up Cemetery Ridge?
If you don't have time to construct a posting with more detail than this, I don't have time to respond.
