“Securing Kentucky to the Union constituted one of the major goals and turning points in the eventual success of the Union in the western theater even if some Kentuckians were frustrated in their desire both to remain in the Union and to retain their property in persons, a frustration that extended to both the commonwealth and the federal government.
Its waterways—the long, winding northern border of the Ohio River (one of the major natural water highways of the nineteenth century) and the western border on the Mississippi—formed a natural southern border with the loyal states of Ohio, Indiana, and Illinois. To lose Kentucky to the Confederacy meant placing the front lines of the war at Cincinnati, Ohio, New Albany, Indiana, and Cairo, Illinois, not the Cumberland Gap and Bowling Green, Kentucky, and Knoxville, Nashville, and Memphis, Tennessee.”
