Many people visit cemeteries and memorials on Memorial Day, particularly to honor those who died in military service. Many volunteers place an American flag on each grave in national cemeteries.
On May 1, 1865, in Charleston, South Carolina, recently freed African-Americans held a parade of 10,000 people to honor 257 dead Union Soldiers, whose remains they had reburied from a mass grave in a Confederate prison camp. Historian David W. Blight cites contemporary news reports of this incident in the Charleston Daily Courier and the New-York Tribune.
