1. The Chattanooga Campaign ed. by Steven E. Woodworth and Charles D. Grear (SIUP, 2012).
The third volume in SIUP's Civil War Campaigns in the Heartland series.
2. One Drop in a Sea of Blue: The Liberators of the Ninth Minnesota by John B. Lundstrom (Minn Hist Society Pr, 2012).
A thick regimental history, this book details the 9th's military service in Missouri, Mississippi (where they played a key role at Brice's Crossroads), Tennessee (Nashville), and Alabama (Mobile). Many of its members also languished in Andersonville prison. The 'liberators' moniker stems from a Missouri event involving 38 soldiers who blocked the attempted recovery of a family of fugitive slaves. The owner being a loyal Unionist, the men were arrested and held on mutiny charges.
