After the Civil War
ended, soldiers were invited to a Grand Review of the Armies in Washington, D.C. Thousands of white soldiers paraded through the streets, lauded by crowds of people. The black soldiers who fought in the war were not invited. Black women in Harrisburg were outraged and organized their own Grand Review. Black soldiers from 25 states attended a Review that marched from the capitol to Simon Cameron's Mansion on November 14, 1865. On November 5 -7 this march is being recreated and descendants of the original marchers are being sought. See this website for the details.
