When I was at East Texas State University back in the Stone Age, I did an honors thesis on Smith County, Texas, During the Civil War. The following year (1977) the Smith County Historical Society published it as a small book, now long out of print. This is basically a paragraph from page 37. But to get to the primary sources, I used the Tyler Reporter (newspaper) a lot, the Smith County Commissioners Court minutes (a polling place was set up in each camp), an item out of Winkler's "Checklist of Texas Imprints, 1861-1876" published in the Southwestern Historical Quarterly, and notes taken from a typescript of the Tyler Post Order Book. I've since found a few other things here and there concerning the camps around Tyler, the men passing through, and the assistance rendered by local women.
I've not done much work on the 11th Texas as unit, though.
