More than 53,000 Union and Confederate veterans from 47 states converged on the battlefield for the June 29-July 4 festivities, making it perhaps the biggest such military reunion in American history. Despite the segregation and racism of the time, black veterans from both the Union and Confederacy were also among the attendees.
Another newspaper sory using the "It was written" source that can't be verified? At least this one isn't claiming the rebel vets welcomed the black vets into their lodgings with open arms.
