nst Bragg, was relieved of the command of the Army of the Cumberland, which fell to Rosecrans, who had achieved success at Corinth, during the fall. McClellan, because of his failure to follow Lee after Antietam, was ordered to turn over the Command of the Army of the Potomac to Burnside. As the end of the year drew nigh, Rosecrans was established with his army at Nashville, and Bragg was at Murfreesboro, 30 miles south. The events of that season were well calculated to enthuse the Confederate and to depress the Federal force. On December 13 was fought the Battle of Fredericksburg, where the Army of the Potomac was repulsed, with frightful slaughter, by the Army of Northern Virginia, under Lee. A week later, the immense depot of supplies at Holly Springs,--supplies that Grant had gathered to aid him in his campaign against Vicksburg,--was captured. On December 29, Sherman, in a preliminary movement of this campaign, was hurled back, stunned and bleeding, from an assault upon Chickasaw Bluffs.
