campaigns by Union forces earlier in 1862 had reaped much progress. The Tennessee and Cumberland Rivers had been opened to the U.S. Navy after successes at the battles of Fort Henry and Fort Donelson. The railroad hub at Corinth had been evacuated by the Confederates, causing most of West Tennessee to fall into Union control. New Orleans, the Confederacy's largest city at that time, had been captured by Admiral David Farragut. The city of Vicksburg, Mississippi, was now an important strategic aim for the Union commanders, as the western Confederates were "narrowed down all to the single line of road running east from Vicksburg." Consequentially, protecting the Confederate stronghold on the Mississippi River became a top priority for the Confederacy. Confederate General Braxton Bragg decided to divert Union attention away from Vicksburg and from Chattanooga, Tennessee, which was being threatened by a large Union force under Don Carlos Buell, by invading the border state of Kentucky. Kentucky, the most southern of the border states, produced cotton and tobacco, and was the primary supplier of hemp for rope used in the cotton industry. The state was also a major slave trade center. Kentucky, being a border state, was among the chief places where the "Brother against brother" scenario was prevalent. Southern sympathizers in Kentucky had already seceded and joined the Confederacy, but had been unable to enforce their rule over the state's territory. Kentucky officially declared its neutrality at the beginning of the war, but after Confederate General Leonidas Polk unwisely decided to occupy Columbus in 1861, the legislature petitioned the Union Army for assistance. After early 1862 Kentucky came largely under Union control. But Kentucky also had a star on the Confederate flag, and seats in the Confederate Congress. In addition, many Confederate leaders, including John C. Breckinridge, were from Kentucky. Most of Mary Todd Lincoln's relatives from the Lexington, Kentucky area were Confederate officers, and about 35,000 Kentuckians served as Confederate soldiers. But an estimated 125,000 Kentuckians served as Union soldiers. Nearly 60 infantry regiments served in the Union armies, versus just 9 in the Confederate. However, a rather large number of cavalry outfits joined the latter.
Campaign
In August 1862, Confederate General Braxton Bragg invaded Kentucky, hoping that he could arouse supporters of the Confederate cause in the border state and draw Union forces under Maj. Gen. Don Carlos Buell back beyond the Ohio River. Bragg transported all of his infantry by railroads from Tupelo, Mississippi, to Chattanooga, Tennessee, while his cavalry and artillery moved by road. By moving his army to Chattanooga, he was able to challenge Buell's advance on the city. as depicted in Harper's Weekly Once his forces had assembled in Chattanooga, Bragg then planned to move north into Kentucky in cooperation with Lt. Gen. Edmund Kirby Smith, who was commanding a separate force operating out of Knoxville, Tennessee. He captured over 4,000 Union soldiers at Munfordville, and then moved his army to Bardstown. On October 4, 1862, he participated in the inauguration of Richard Hawes as the provisional Confederate governor of Kentucky. The wing of Bragg's army under Maj. Gen. Leonidas Polk met Buell's army at Perryville on October 8 and won a tactical victory against him. , commanding general of the Union's Army of the Ohio Kirby Smith pleaded with Bragg to follow up on his success: "For God's sake, General, let us fight Buell here." Bragg replied, "I will do it, sir," but then displaying what one observer called "a perplexity and vacillation which had now become simply appalling to Smith, to Hardee, and to Polk," he ordered his army to retreat through the Cumberland Gap to Knoxville. Bragg referred to his retreat as a withdrawal, the successful culmination of a giant raid. He had multiple reasons for withdrawing. Disheartening news had arrived from North Mississippi that Earl Van Dorn and Sterling Price had failed at Corinth, just as Robert E. Lee had failed in his Maryland Campaign. He saw that his army had not much to gain from a further, isolated victory, whereas a defeat might cost not only the bountiful food and supplies yet collected, but also his army. He wrote to his wife, "With the whole southwest thus in the enemy's possession, my crime would have been unpardonable had I kept my noble little army to be ice-bound in the northern clime, without tents or shoes, and obliged to forage daily for bread, etc."
Aftermath
The invasion of Kentucky was a strategic failure, although it had forced the Union forces out of Northern Alabama and most of Middle Tennessee; it would take the Union forces a year to regain the lost ground. Bragg was criticized by some newspapers and two of his own generals, Polk and William J. Hardee, but there was plenty of blame to spread among the Confederate high command for the failure of the invasion of Kentucky. The armies of Bragg and Kirby Smith suffered from a lack of unified command. Bragg can be faulted for moving his army away from Munfordville, out of Buell's path, a prime location for a battle to Confederate advantage. Polk can also be blamed for not following Bragg's instructions on the day before and the day of the battle. Confederate President Jefferson Davis kept Bragg in command of the Army of Tennessee. President Abraham Lincoln removed Buell from command of the Army of the Ohio for being too cautious in pursuit of Bragg, replacing him with Major General William Rosecrans.
