NYTimes actually reflects:
But for the earliest and most remarkable Memorial Day, we must return to where the war began. By the spring of 1865, after a long siege and prolonged bombardment, the beautiful port city of Charleston, S.C., lay in ruin and occupied by Union troops. Among the first soldiers to enter and march up Meeting Street singing liberation songs was the 21st United States Colored Infantry; their commander accepted the city's official surrender. Whites had largely abandoned the city, 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 freedpeople, 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.
Sometimes the facts do all the talking.
