1. More Than Freedom: Fighting for Black Citizenship in a White Republic, 1829-1889 by Stephen Kantrowitz (Penguin, 2013).
Kantrowitz attempts to "show how the fight to abolish slavery was always part of a much broader campaign by African Americans to claim full citizenship and to remake the white republic into a place where they could belong."

A history (the first book length treatment?) of the famed Chamberlain-Gordon connection.
3. The College of William and Mary in the Civil War by Sean M. Heuvel and Lisa L. Heuvel (McFarland, 2013).
The book "describes the fate of the College and also explores in-depth the war service of the College's students, faculty, and alumni, ranging from little-known individuals to historically prominent figures such as Winfield Scott, John Tyler, and John J. Crittenden. The College's many contributions to the Civil War and its role in shaping pre- and post-war higher education in the South are fully revealed".
