For two weeks there had been no communication between Burnside and the outer world. Lincoln had been full of anxiety, but had found some comfort in the reports from Cumberland Gap that cannonading was still heard in the direction of Knoxville. It proved that Burnside held out, and gave additional earnestness to the President's exhortation to hurry a column to his relief immediately after Grant's victory. Grant needed no urging. A report had reached him that Burnside still was confident on the 23d, and had supplies for ten or twelve days on the scale of short rations he was issuing. On the very evening of his success he wrote to Sherman, "The next thing now will be to relieve Burnside." He directed Thomas to detach Granger's Corps, and this with part of the Army of the Tennessee would make a column of 20,000 men to march at once for Knoxville under Granger's command. Three days passed, and Grant, being dissatisfied that the relieving column was not already far on its way, directed Sherman on the 29th to take command in person and push it energetically toward Burnside. [Footnote: Official Records, vol. xxxi. pt. ii. pp. 45, 49; Sherman's Memoirs, vol. i. pp. 366, 368.] Sherman immediately went forward, and on the 1st of December he was over the Hiwassee River, approaching Loudon. He telegraphed Grant that he would let Burnside hear his guns on the 3d or 4th at farthest; but he added what throws much light on the feeling of military men in regard to campaigning in East Tennessee. In his frank and familiar style he said, "Recollect that East Tennessee is my horror. That any military man should send a force into East Tennessee puzzles me. Burnside is there and must be relieved; but when relieved, I want to get out and he should come out too." [Footnote: Official Records, vol. xxxi. pt. iii. p. 297.] From a strictly military point of view this was sound; but Burnside had been sent there more from political than from military reasons, and it was now too late to think of letting the loyal mountaineers return under Confederate rule.
