There is a great song by The Cutters: Fields of Gettysburg -- written by Phillip Morgan, quoted from the liner notes: behind the song,"Phillip's twice great grandfather, Creed Henry Harper, enlisted in the Confederate Army at age 16, two weeks after Virginia seceded. He was one of five brothers from a family that had freed their slaves years before. All five enlisted, out of love and loyalty to Virginia and to a Southern way of life. At Gettysburg, he was a first sergeant of Company C of the 53rd Virginia Infantry in Armistead's brigade of Pickett's Division. This song is largely his own words, passed down by Phillip's maternal grandmother, who was raised by him."
