General John Bell Hood of the Confederate Army of Tennessee attempted to capture Nashville, the final realistic chance for a battlefield victory against the Northern juggernaut. Hood's former West Point instructor, Major General George Henry Thomas, led the Union force, fighting those who doubted him in his own army as well as Hood's Confederates. Through the bloody, horrific battles at Spring Hill, Franklin and Nashville and a freezing retreat to the Tennessee River, Hood ultimately failed. Civil War historian James R. Knight chronicles the Confederacy's last real hope at victory and its bitter disappointment.
