1. Born to Battle: Grant and Forrest--Shiloh, Vicksburg, and Chattanooga by Jack Hurst (Basic Books, 2012).
Hurst continues his series juxtaposing the personal backgrounds and military careers of Grant and Forrest. I still think it a bit odd to pair two guys with such a large gap in respective command responsibilities.
2. Rhode Island's Civil War Hospital: Life and Death at Portsmouth Grove, 1862-1865 by Frank L. Grzyb (McFarland, 2012).
Portsmouth Grove Hospital served thousands of Union wounded and Confederate prisoners. This well researched and illustrated book examines the levels of care offered at the facility and the lives of patients, staff, and civilian benefactors. A roster of soldiers serving as hospital guards is included, as well as a burial register of those that died at the hospital.
