Offers an in-depth examination of Alabama's black and white Union soldiers and their contributions to the eventual success of the Union army. Christopher Rein contends that the state's anti-Confederate residents tendered an important service to the North, primarily by collecting intelligence and protecting logistical infrastructure.

"Alabamians in Blue is a well researched and revealing study white and black enlistees in Union army regiments. Christopher Rein presents a complex story on a large canvass but with fine detail that reveals the importance of environmental factors, social divisions, racial ideology, and soldier motivation in understanding how the American Civil War unfolded on the ground. This creatively conceived book offers a compelling account of ordinary people buffeted by the cruel winds of war." --George C. Rable, University of Alabama, Emeritus, and author of Damn Yankees! Demonization and the Defiance in the Confederate South
