Erica,
Here are two sources I had on the shelf.
Look to the Earth: Historical Archaeology and the American Civil War. edited
by
Clarence R. Geier, Jr and Susan E. Winter. 1994 University of Tennessee
Press
The Sevierville Hill Site: A Civil War Union Encampment on the Southern
Heights of Knoxville, Tennessee . edited by Charles Bentz and Yong W. Kim.
Tennessee Anthropological Association Miscellaneous Paper No 17. University
of Tennessee Transportation Center Report of Investigations No 1.
Also, try the TennArch website, look for Sam Smiths email address at the
State Archaeologists office, he has been conducting an ongoing Civil War site
inventory and may be able to help.
