David Andrew Shields was killed by Union soldiers defending Harper's Ferry on September 13th of 1862. Aliene Shields made the trip from South Carolina in honor of her great-great-uncle.
"We have never forgotten him, even 150 years later," she says.
Exactly 150 years to the day, his family gathered at the Brownsville Church of the Brethren, in front of the mountain ridge where he died.
A memorial stone with his name will sit at the base of the battlefield.
"It's something to be proud of, its something to look back on and see what our forefathers and foremothers have done before us," Shields says.
