In 1862, with the outcome of the Civil War far from certain, Union and Confederate leaders began to pinpoint locations vital for their army's success. Tennessee was one such possession. Although nominally under Confederate control, with Union loyalists in the east, Confederate supporters in the west and a mixture in the central region, the state did not have ironclad loyalty to either cause. For the Union, gaining control of Tennessee meant crippling the transportation options of the Confederacy, giving Union forces access to the rivers and mountain passes which would potentially lead them to the heart of the Confederacy and victory over the South. For the Confederacy, maintaining control of Tennessee was vital not only to protect its southernmost states but also to retain control of the state's agricultural products and mineral wealth, neither of which it could afford to lose.
