Query: Pure Racist Bias

In his effort to achieve political correctness, Quarles coveniently leaves out the 60,000 black soldiers who fought proudly and bravely for their country - The Confederate States of America. Even though the "purge" of photos and records of black Confederates from 1890 to 1930 was extensive, many records, photos, and stories passed down still survive. If the reader doubts this, there are several books that tell the well documented truth available, including "Black Confederates" by Barrow, Segars, and Rosenburg.
