I believe there was a totally black regiment in the Revolutionary War in one of the New England states. Walker who used to be the Archivist at the Library of Congress wrote a book about this regiment. I heard him speak many years ago about them. I would also check the NSDAR as many of the soldiers and others who gave service in that War, were black. (www.dar.org). Blacks have always tried to help their country. There were black regiments in all the wars, including the famous Buffalo Soldiers. Annie
