Sir,
Books that I recommend you start with:
Bentonville: The Final Battle of Sherman & Johnston by Nathaniel Cheairs Hughes, Jr. University of North Carolina Press, Chapel Hill and London, 1996.
Moore's Historical Guide to the Battle of Bentonville by Mark A. Moore, Savas Publishing Company, 1997.
Last Stand in the Carolinas: The Battle of Bentonville by Mark L. Bradley. Savas Woodbury Publishers, 1996.
Homeward Bound: The Demobilization of the Union and Confederate Armies, 1865- 1866 by William B. Holberton. Stackpole Books, Mechanicsburg, PA, 2001.
This Astounding Close: The Road to Bennett Place by Mark L. Bradley. University of North Carolina Press, Chapel Hill and London, 2000.
Also, of course, the Official Records of the War of Rebellion.
There are points of the retreat from Nashville that I am intensely interesting in from the point of view of the regiment and the brigade I research. Please let me know if you have any questions.
Respectfully,
Gerald D. Hodge, Jr.
