The first Decoration Day, as the commemoration of the nation’s war dead was originally called, was observed on May 1, 1865. The African American origin of the holiday was suppressed by white Southerners. David W. Blight, a professor of history and the director of the Gilder Lehrman Center for the Study of Slavery, Resistance and Abolition at Yale University, discovered the hidden history while digging through the archives at Harvard University.
In a 2011 op-ed piece in the New York Times, Dr. Blight wrote:
Whites had largely abandoned the city [Charleston, SC], but thousands of blacks, mostly former slaves, had remained, and they conducted a series of commemorations to declare their sense of the meaning of the war.
The largest of these events, forgotten until I had some extraordinary luck in an archive at Harvard, took place on May 1, 1865. During the final year of the war, the Confederates had converted the city’s Washington Race Course and Jockey Club into an outdoor prison. Union captives were kept in horrible conditions in the interior of the track; at least 257 died of disease and were hastily buried in a mass grave behind the grandstand.
After the Confederate evacuation of Charleston black workmen went to the site, reburied 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.”
The symbolic power of this Low Country planter aristocracy’s bastion was not lost on the freed people, who then, in cooperation with white missionaries and teachers, staged a parade of 10,000 on the track. 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.”
The procession was led by 3,000 black schoolchildren carrying armloads of roses and singing the Union marching song “John Brown’s Body.” Several hundred black women followed with baskets of flowers, wreaths and crosses. Then came black men marching in cadence, followed by contingents of Union infantrymen. Within the cemetery enclosure a black children’s choir sang “We’ll Rally Around the Flag,” the “Star-Spangled Banner” and spirituals before a series of black ministers read from the Bible.
