The initiative to invade Kentucky came primarily from Confederate Maj. Gen. Edmund Kirby Smith, commander of the Department of East Tennessee. He believed the campaign would allow them to obtain supplies, enlist recruits, divert Union troops from Tennessee, and claim Kentucky for the Confederacy. In July 1862 Col. John Hunt Morgan carried out a successful cavalry raid in the state, venturing deeply into the rear areas of Buell's department. The raid caused considerable consternation in Buell's command and in Washington, D.C. During the raid, Morgan and his forces were cheered and supported by many residents. He added 300 Kentucky volunteers to his 900-man force during the raid. He confidently promised Kirby Smith, "The whole country can be secured, and 25,000 or 30,000 men will join you at once."
