Battery I was formed in 1861 by Charles W. Keith of Joliet and Henry B. Plant of Peoria. More than a hundred men were mustered into service in December near Springfield and left for Cairo in February 1862. The battery trained at Camp Paine across the Ohio River in Kentucky until March, when the men were dispatched to the South. During the war, the Battery was attached to three different armies: the Army of the Mississippi, the Army of the Ohio, and the Army of the Cumberland.
Clyde C. Walton’s foreword and the narrative discuss the variety of weapons used by the unit, including James, Parrott, and Rodman guns and the bronze, muzzle-loading Napoleons that fired twelve-pound projectiles. The book also includes an account of the prisoner-of-war experience of Battery I lieutenant Charles McDonald, biographical sketches of the battery soldiers, and eighteen maps and five line drawings.
