1. The Civil War in the Border South by Christopher Phillips (Praeger, 2013).
I haven't had the chance to see much of this series of introductory histories to various Civil War subjects, but liked the one that I did read (Daniel Sutherland's American Civil War Guerrillas).
2. The Bloody 7th by Glen Allan Swain, Jr. (Broadfoot, 2014).
This is one of the newest volumes from the South Carolina Regimental-Roster series. The 7th certainly forged an enviable reputation within Kershaw's brigade. Author Glen Swain also revealed that 8th and 20th volumes are on the way (from different authors), these last two filling out the brigade's full complement of subunits.
3. The Last Citadel: Petersburg, June 1864 - April 1865 by Noah Andre Trudeau (Savas Beatie, 2014).
It's probably safe to say that for many Civil War readers Trudeau's The Last Citadel served as their first comprehensive introduction to the Petersburg Campaign. The just released "150th Anniversary Edition" from Savas Beatie has "updated text, redrawn maps, and new material."
