I also show Oliver Buntin in the Pickens Greys [the "second" Pickens Greys formed, as opposed to the original which was assigned to the 41st Ala. Inf.]
This company was organized at Bridgeville on 5/23/1863 for the "purpose of home defense". Members were equipped mostly with shotguns, with just a few rifles.
This is most likely part of the "home guard from Bridgeville and Carrollton" which engaged Sutherland between Garden and Carrollton, and again at King's Store.
