1. Grant at Vicksburg: The General and the Siege by Michael B. Ballard (SIUP, 2013).
This the first book length history of the siege portion of the Vicksburg Campaign to appear since the publication of the third volume of Bearss's trilogy. Where Bearss delved into the on-the-ground minutiae associated with each of a series of Vicksburg siege approaches, Ballard offers a more top down "in-depth exploration of Grant’s thoughts and actions during this critical operation."
2. The 6th United States Cavalry in the Civil War: A History and Roster by Donald C. Caughey and Jimmy J. Jones (McFarland, 2013).
Early adopting followers of Civil War blogs and Crossed Sabers in particular will know that Don Caughey has been working on this project, a well researched unit history and detailed roster, for a long time.
