Andrew W Miles enlisted in the 16th Georgia Infantry Company E aka "Cobbs Infantry" which was formed in Habersham County, GA. He was enlisted on July 24, 1861 in Clarkesville, GA by Captain Benjamin Edward Stiles (later appointed LtCol).
Your Andrew W Miles was 5th Sergeant of Co E. Appears on a roll for receipt of clothing dated Nov 27, 1864. There are no cards in his file to indicate he was admitted to the hospital for illness or injury.
The 16th was sent from Athens, GA to Richmond, Va where they were commanded by General Howell Cobb and remained encamped in the city from Aug 1861 through the winter. The regiment had a force of 488 effectives in April, 1862. They fought with Magruder on the Peninsula (Yorktown, Lees Mill, Williamsburg) and the Seven Days Battles (Savages Station, Allens Farm, Malvern Hill.) They were then sent to join the Army of Northern Virginia. They fought at Crampton's Gap South Mountain where 500 Confederates tried to defend against 15,000 approaching Union soldiers; then atAntietam, Fredericksburg, Chancellorsville, and Gettysburg.
The Regiment moved with Longstreet by rail but arrived late and was not engaged at Chickamauga. The Regiment was part of Longstreets force at Knoxville (and Fort Sanders), then returned to Virginia and suffered heavy casualties at The Wilderness and Spotsylvania. They were engaged at North Anna, Cold Harbor, and Petersburg. Later the unit was part of Early's operations in the Shenandoah Valley and the Appomattox Campaign Cedar Creek, Saylors Creek, and Appomattox Court House.
They lost 11 killed and 50 wounded at Malvern Hill, and of the 368 engaged at South Mountain (Crampton's Gap), fifty-two percent were disabled. Sustained 70 casualties in the Sunken Road at Fredericksburg and 133 at Chancellorsville. It is estimated by some that the casualties sustained by the 16th Georgia in the Peach Orchard and the Wheatfield at Gettysburg may have been as high as 34% of the 303 effectives. The 16th lost many at Sayler's Creek and surrendered only 2 officers and 51 men.
Andrew W Miles was there with the 16th Georgia when they surrendered at Appomattox Court House. He would have signed the Oath there and received his pardon.
