1. Embattled Rebel: Jefferson Davis as Commander in Chief by James M. McPherson (Penguin, 2014).
Clearly intended as a companion piece to McPherson's Lincoln as C-in-C book, this one looks like another light popular history in similar vein to that one and the author's more recent naval war overview. When I'm done with it I'm sending it to Dimitri as a Christmas present.
2. The Smell of Battle, the Taste of Siege: A Sensory History of the Civil War by Mark M. Smith (Oxford UP, 2014).
Drawing inspiration from Sumter, First Bull Run, Gettysburg, Vicksburg, and Charleston (the Hunley) events, Smith "considers how all five senses, including sight, shaped the experience of the Civil War and thus its memory, exploring its full sensory impact on everyone from the soldiers on the field to the civilians waiting at home."
3. A Dog Before a Soldier: Almost-lost Episodes in the U.S. Navy's Civil War by Chuck Veit (Author, 2010).
I missed this one when it first came out, but found the author's interview on CWTR to be fascinating. In ten chapters, the book explores the contributions of naval landing parties to Civil War campaigns. As the subtitle suggests, Veit aims for detailing more obscure actions that nevertheless had great impact. For a self-published study, the book's presentation is unusually professional, including footnotes and numerous top quality maps and illustrations.
