Well said
@Cavalry Charger! This is indeed an interesting topic. Clyde Bell was the supervisory ranger at Gettysburg when he died in 2013. He recommended the book,
Wasted Valor: The Confederate Dead at Gettysburg by Gregory A. Coco for folks who want to learn more about the Confederates buried at Gettysburg.
According to a post Mr. Bell made in
The Blog of Gettysburg Military Park, research has found that at least seven Confederate soldiers, through cases of mistaken identity, were buried in the Soldiers’ National Cemetery where six remain to this day. Mr. Bell related the story of Major Benjamin W. Leigh.... "Major Leigh, the assistant adjutant general of General Edward Johnson’s Division, was originally among those buried in the Soldiers’ National Cemetery, but his remains have since been disinterred in the national cemetery, properly identified and sent with proper ceremony to Shockoe Hill Cemetery in Richmond. The initial decision to move the Confederate officer’s remains from his field grave to the national cemetery remains a mystery. Major Leigh was shot down in the final moments of the fighting at Culp’s Hill. His bravery and courage in his final moments was witnessed by numerous Union soldiers, who provided the officer a decent burial on the hill side, going to far as to mark his grave with his initials and unit. He was mistaken during the exhumation process for a Union soldier."
I think the most recent discovery of a Confederate soldier's body occurred in 1995 near the Railroad Cut. The identity of this soldier and the army in which he served could not be readily identified during the archaeological excavation of the remains, but several battle experts believe he fought for the Confederacy and was most likely a Mississippi soldier.
