Smith being among the most common names, it's often easier to narrow the search by focusing on men named George Smith from the same county. In this case the 1860 census for Newton County GA lists George N. Smith, age 18, and George T. Smith, age 15, both of whom should have enrolled during the war. Let's start by identifying George Smiths indexed in companies raised in Newton County GA.

The 3^rd Georgia Sharpshooter Battalion organized in early May 1863 when General Wofford detailed fifty men from each of the five commands in his brigade. Officers and men were already enlisted in Confederate service and serving in Wofford's Brigade. George Smith of Co. "A", 3rd Georgia S.S. Battn., transferred from Co. "B", 18th Georgia Regiment, the "Newton Rifles." You've seen a summary of his capture and imprisonment. This man didn't use a middle initial and his age isn't listed, so you're still not sure about him.

What about other men named George T. Smith, the name you really want? A man named George T. Smith enlisted in Co. "H", 28^th Georgia Regiment. As shown on the 1860 census, he's from Washington County GA.

Only one other man by this name is indexed for a Georgia unit. He belongs to another company from Newton County, Co. "A", Cobb's Georgia Legion. It just so happens that this command also served in Wofford's Brigade, and this soldier was also captured near Farmville VA, Apr. 6, 1865. Interesting coincidence. Age isn't listed, but I believe he's the man you want.
