The Confederate forces had now acquired an advantage which it appears was lost by the detaching of Longstreet on an expedition to drive Burnside from Knoxville; and perhaps also by the neglect of an opportunity for making a united bold advance into Tennessee. At the time that Bragg's forces were thus weakened by the absence of Longstreet and were held as besiegers of Chattanooga in the lines along Missionary ridge and Lookout mountain, Federal reinforcements drawn from Virginia and Tennessee in large numbers were hurried to the relief of Rosecrans. General Grant was also ordered to take command and Rosecrans was relieved.
About the middle of November the Federal army had been increased to 80,000 men, nearly doubling the force of Bragg, and inspired with confidence by the arrival of a new commander. Confiding in this force and appreciating the value of a quick blow while Longstreet was away, General Grant moved against Bragg, and on November 25th drove him from Lookout mountain and Missionary ridge to a new position near Dalton, in Georgia. This much accomplished, a large reinforcement was sent rapidly to Burnside, at Knoxville, causing Longstreet to withdraw toward Virginia.
