Many blacks fought for and served in the Army of the Confederacy with distinction. This is a fact recognized by the Union at the time. Many blacks fought believing it would move them closer to freedom—we shall never know if this would have happened—but it was possible. Only with the Civil Rights Movement—and opposition of the so called Dixiecrats that the battle flag of the CSA has been vilified as a hate symbol. Others fought for the south as well—Cherokee Indians, and others. Some from the North came to defend the idea of succession. Black Confederates need to be honored—there is a group that needs a monument!
This includes a monument at Arlington Cemetery: http://www.blackconfederatesoldiers.com/black_soldiers_memorials_5.html
