All but a few members of the Fifty-seventh lived within a close radius of eighty miles from each other. More than just an account of their military engagements, this is a collective biography of a close-knit group. Relatives and neighbors served and died side by side in the Fifty-seventh, and Walker excels at showing how family ties, friendships, and other intimate dynamics played out in wartime settings. Humane but not sentimental, the history abounds in episodes of real feeling: a starving soldier’s theft of a pie; another’s open confession, in a letter to his wife, that he may desert; a slave’s travails as a camp orderly.

Drawing on memoirs and a trove of unpublished letters and diaries, Walker follows the soldiers of the Fifty-seventh as they push far into Unionist Kentucky, starve at the siege of Vicksburg, guard Union prisoners at the Andersonville stockade, defend Atlanta from Sherman, and more. Hardened fighters who would wish hell on an incompetent superior but break down at the sight of a dying Yankee, these are real people, as rarely seen in other Civil War histories.
