There is an historical marker there at the cemetery which reads:
“Here are buried 268 Confederate Soldiers most of whom died of wounds or
Disease in the several Confederate hospitals located in Newnan. Some were
killed in the battle fought south of here, 30 July 1864. Due to the efficiency of
the local hospitals, only two are “Unknown.” Most of these men were veterans
of many hard fought battles. Every state in the Confederacy is represented in
these burials. Also, buried here are two Revolutionary War Soldiers, and onefrom the First World War.”
One on end of the Confederate Cemetery there is a wonderful monument erected by the Ladies Memorial Association which has two crossed flags on the top with the inscription, "Our Confederate Dead. No cause e're rose so just and true, none fell so free from crime."
Certainly the most famous grave at Newnan's Oak Hill Cemetery is that of Private William Thomas Overby who was posthumously awarded the Confederate Medal of Honor. His grave is located adjacent to the Ladies Memorial and a flagpole flying the Confederate Battle Flag. The local Sons of Confederate Veterans Sharpsburg Sharpshooters Camp 1729 reinterred Pvt Overby in a January 1997 funeral with full military honors and placed a beautiful memorial granite slab over his grave. Pvt Overby was known as the Nathan Hale of the Confederacy; he was executed as a spy after he was captured by Union troops and refused to divulge the whereabouts of the headquarters of his commander Confederate Cavalry Colonel John Singleton Mosby. http://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GRid=13378985 provides a short synopsis of the story of Pvt Overby but there are volumes written about Overby including the book of his name "William Thomas Overby Proud Partisan Ranger".
