Lieutenant General Leonidas Polk was a distinguished West Point graduate, the first Episcopal Bishop of Louisiana, a university founder, and a Confederate commander beloved by his troops, esteemed by the public, and killed on the field of battle. In spite of his many accomplishments, historians invariably disparage Polk's generalship and even his personal character--but is their treatment fair or accurate? This work employs a balanced perspective to shed new light on Polk's military leadership and reveal unexpected truths that explain his conflict with General Braxton Bragg. A seemingly insignificant piece of correspondence, along with an exploration of both men's writings, coalesce into an understanding of the root cause of the command dysfunction and chronic failures of the Army of Tennessee.
