I don't see prior military service for John L. Lewis. The earliest date you can assign to him would be Sept. 4, 1863, as shown on the company roll. This company enrolled in Confederate service at Elyton AL, members served under orders of the Conscript Bureau in Jefferson County, 2nd Congressional District of Alabama.
I have an ancestor in the same company. Capt. Truss and his men served as military police in Jefferson, St. Clair and Shelby Counties.
