Always glad to help out a fellow researcher. I wish I could be more prompt and devote more time in my responses, because I really like the work you're doing. But right now I'm juggling a couple of research projects of my own, and going back and forth between my research and yours is a strain on my aging brain cells. Anyway, I'll do the best I can -- I just might not be as quick on the draw as I'd like to be.

Anyhow, here are the specifics of the companies which composed Williamson's short-lived battalion --

Co. A--Franklin county (enlisted at Ozark, Arkansas, February 8, 1862)
Co. B--Franklin county (enlisted at Ozark, Arkansas, February 15, 1862)
Co. C--Pope county (enlisted in Pope county, Arkansas, February 15, 1862)
Co. D--Pope county (enlisted at Russellville, Arkansas, February 13, 1862)
Co. E--Pope county (enlisted at Dover, Arkansas, February 22, 1862)
Co. F--Yell county (enlisted at Bata’s Mill, Arkansas, February 28, 1862)
Co. G--Yell county (enlisted at Dardanelle, Arkansas, February 28, 1862)
Co. H--Conway county (enlisted at Portland, Arkansas, March 1, 1862)

The battalion was still recruiting and organizing when it was swept up by General Van Dorn (along with everything else that wasn't nailed down) when he left Arkansas and took his army to Mississippi. It was apparently intended to be recruited to a full regiment. When they got to Mississippi, the battalion was formally organized for the war at Camp Churchill Clark, near Corinth, Mississippi, on May 8, 1862. However, it was decided to disband the battalion instead, so the election of officers was invalidated and the battalion formally broken up on May 25, 1862. The component companies were distributed among other Arkansas battalions and regiments.
