1st Sgt Mathew G Wiggtinton, Co I, 48th Alabama Regt, went to Talladega to receive a parole on May 23, 1865. On Mar 21, 1865, he had sent sent home on furlough, leaving Jackson Hospital at Richmond, Va. Wigginton had been there since being exchanged nearby on prisoner-of-war release in early March 1865.
On Dec 3, 1863, Sgt Wigginton had been captured during Longstreet's retreat from Knoxville and sent to prison at Rock Island, Ill. His Confederate service record reports date of capture as Dec 4, 1863, Loudon, Tenn. Listed as "absent, sick" on the compiled company roster during the Battle of Knoxville, Nov 25, 1863, Wigginton could have been left in a hospital and captured there.
The compiled roster from the ADAH shows that Mathew G Wigginton missed Gettysburg, being absent - sick, but served both days at Chickamauga. He was appointed 1st Sergeant from the ranks on Sept 20, 1863. An earlier injury received in battle kept him in different hospitals from September 1862 until Apr 4, 1863.
A year earlier Wigginton had been wounded in the left thigh during the Battle of Sharpsburg, Md. There were more American casualties on this day at Sharpsburg than during the American Revolution, the War of 1812 and the Mexican War combined. The casualty total at Sharpsburg equaled that of the two-day Battle of Shiloh.
Here's a link to media about the 48th Alabama in that battle --
Wigginton had been present during the capture of Harpers Ferry, a just a day or so earlier, but Sharpsburg was his first real battle. He enlisted Apr 26, 1862, at age 26, Abernathy, Calhoun County, Ala. The consolidated roll shows him a resident of Kemp's Creek, and married. I don't see his name or Louisa's listed on the 1866 state census of Alabama.
Wigginton's military service file contains most of this information and many other documents, some with his signature. Copies can be ordered through this message board.
