1. The Battle of Monroe's Crossroads and the Civil War's Final Campaign by Eric J. Wittenberg (Savas Beatie, 2015).
Originally published in hardcover in 2006 and newly released in paperback, this book is an essential part of the 1865 Carolinas Campaign library. To read my review, go here.
2. Lincoln and the Jews: A History by Jonathan D. Sarna and Benjamin Shapell (Thomas Dunne Books, 2015).
This is an oversize (almost coffee table dimensions) pictorial and documentary study that "provides readers both with a captivating narrative of [Lincoln's] interactions with Jews, and with the opportunity to immerse themselves in rare manuscripts and images, many from the Shapell Lincoln Collection,..." Sarna and Shapell "reveal how Lincoln's remarkable relationship with American Jews impacted both his path to the presidency and his policy decisions as president."
