Here is an excerpt from an article "Black Confederate Soldiers" by the black George Mason professor (who sometimes fills in for Rush) Walter Williams (Source: http://www.lizmichael.com/blkconfd.htm )
"DURING OUR WAR OF 1861, ex-slave Frederick Douglass observed, "There are at the present moment, many colored men in the Confederate Army doing duty ... as real soldiers, having muskets on their shoulders and bullets in their pockets, ready to shoot down ... and do all that soldiers may do to destroy the Federal government." ... Erwin L. Jordan's book "Black Confederates and Afro-Yankees in Civil War Virginia" cites eyewitness accounts of the Antietam campaign of "armed blacks in rebel columns bearing rifles, sabers, and knives and carrying knapsacks and haversacks." ...
In April 1861, a Petersburg, Virginia newspaper proposed "three cheers for the patriotic free Negroes of Lynchburg" after 70 blacks offered "to act in whatever capacity may be assigned to them" in defense of Virginia. Erwin L. Jordan cites one case where a captured group of white slave owners and blacks were offered freedom if they would take an oath of allegiance to the United States. One free black indignantly replied, "I can't take no such oaf as dat. I'm a secesh nigger." ... A second slave said, "I ain't going out here on no dishonorable terms." One of the slave owners took the oath but his slave, who didn't take the oath, returning to Virginia under a flag of truce, expressed disgust at his master's disloyalty saying, "Massa had no principles."
... These are but a few examples of the important role that blacks served, both as slaves and freemen in the Confederacy during the War Between the States.
The flap over the Confederate flag is not quite as simple as the nation's race experts make it. They want us to believe the flag is a symbol of racism. Yes, racists have used the Confederate flag, but racists have also used the Bible and the U.S. flag. Should we get rid of the Bible and lower the U.S. flag? Black civil rights activists and their white liberal supporters who're attacking the Confederate flag have committed a deep, despicable dishonor to our patriotic black ancestors who marched, fought and died to protect their homeland from what they saw as Northern aggression.
They don't deserve the dishonor. "
