Michael, I had not replied to your earlier request as I could not pin an individual down as not surviving the war. Using civilwardata.com, when I query "A.James, they list 114 CS soldiers. James is a fairly common surname. The list seldom has info on CS individuals as to whether they survived the war. Looking at the 114, the site lists 4 "A.James; 50 with various given names beginning with "A", but no mid initial. All these records would have to be researched.
There are two additional records that might be your man. A.F.James, a corporal, was in the Texas 9th cavalry, Co E. Ashbell F.James of the Virginia 20 cavalry, Co F.
Best of luck with your search.
