The 51st Regiment, Tennessee Infantry was organized at Henderson Station, Tennessee, in January, 1862. The 52nd was also organized at the same time with men from Tipton, Fayette, Shelby, Madison, and Jackson counties. A detachment of the 52nd was captured at Fort Donelson, then in October it was active in the fight at Perryville. Later the unit was assigned to D.S. Donelson's, M.J. Wright's, Vaughan's, and Palmer's Brigade. During April, 1862, it was consolidated with the 52nd Regiment and called the 51st Consolidated.

It participated in many battles of the Army of Tennessee from Murfreesboro to Atlanta, returned to Tennessee with Hood, and was involved in the North Carolina Campaign.

The Nashville Campaign, culminating with the last major battle of the Civil War, is one of the most compelling and controversial campaigns of the conflict. The campaign pitted the young and energetic James Harrison Wilson and his Union cavalry against the cunning and experienced Nathan Bedford Forrest with his Confederate cavalry. This book is an analysis of contributions made by the two opposing cavalry forces and provides new insights and details into the actions of the cavalry during the battle. This campaign highlighted important changes in cavalry tactics and never in the Civil War was there closer support by the cavalry for infantry actions than for the Union forces in the Battle of Nashville. The retreat by Cheatham's corps and the Battle of the Barricade receive a more in-depth discussion than in previous works on this battle. The importance of this campaign cannot be overstated as a different outcome of this battle could have altered history. The Nashville Campaign reflected the stark realities of the war across the country in December 1864 and would mark an important part of the death knell for the Confederacy.
