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 northern Mississippi that Earl Van Dorn and Sterling Price had been defeated 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." He was quickly called to Richmond to explain to Jefferson Davis the charges brought by his officers about how he had conducted his campaign, demanding that he be replaced as head of the army. Although Davis decided to leave the general in command, Bragg's relationship with his subordinates would be severely damaged. Upon rejoining the army, he ordered a movement to Murfreesboro, Tennessee.
