Best I can tell, there is no service record under the name Isaac Beeson or a similar spelling. If you have all the papers submitted, it may include the names of witnesses for Confederate service, as well as the names of officers under which the veteran was said to have served. Any other details from the pension would be helpful.

Also, best I can tell, Isaac Beeson is one of several men from St. Clair, Blount and DeKalb by that name for whom no service can be determined. Others are James H., William P., William S. and Henry Beason/Beeson. Also, Jasper H. Beason of St. Clair County was taken to Camp of Instruction at Talladega but I find no service in an actual military command.
