The source for Barkley's wounding story came from his Confederate pension application, filed in Bibb County, GA.
The 31st GA casualty list for Sharpsburg, MD (9/17/1862) was published in the 10/27/1862 "Columbus Daily Times".
I believe Monroe County (Forsyth, GA) had a weekly publication, but there are no known surviving copies that I am
aware of. I've located a lot of war-related Monroe County info. in the "Macon Telegraph" newspaper. Macon is in neighboring Bibb County.
I'd love to obtain a copy of your Barkley image. I'm toying with the idea of writing a Maryland Campaign history
for Lawton's Brigade (13th-26th-31st-38th-60th & 61st GA regiments).
Six of my ancestors served in Company D ("Monroe Crowders") with Barkley.
Sincerely,
Gregory C. White
