Professor David Blight of Yale writes of “The First Decoration Day” on May 1, 1865.
“Union soldiers were kept in horrible conditions in the interior of the track; at least 257 died of exposure and disease and were hastily buried in a mass grave behind the grandstand. Some twenty-eight black workmen went to the site, re-buried the Union dead properly, and built a high fence around the cemetery. They whitewashed the fence and built an archway over an entrance on which they inscribed the words, ‘Martyrs of the Race Course.’
“Then, black Charlestonians in cooperation with white missionaries and teachers, staged an unforgettable parade of 10,000 people on the slaveholders’ race course. The symbolic power of the low-country planter aristocracy’s horse track (where they had displayed their wealth, leisure, and influence) was not lost on the freedpeople. A New York Tribune correspondent witnessed the event, describing ‘a procession of friends and mourners as South Carolina and the United States never saw before.’
“At 9 am on May 1, the procession stepped off led by three thousand black schoolchildren carrying arm loads of roses and singing ‘John Brown’s Body.’ The children were followed by several hundred black women with baskets of flowers, wreaths and crosses. Then came black men marching in cadence, followed by contingents of Union infantry and other black and white citizens.”
