What impact did Sherman's campaign have on Confederate morale?

After General John Bell Hood abandoned Atlanta, he moved the Confederate Army of Tennessee outside the city to recuperate from the previous campaign. In early October he began a raid toward Chattanooga, Tennessee, in an effort to draw Sherman back over ground the two sides had fought for since May. But instead of tempting Sherman to battle, Hood turned his army west and marched into Alabama, abandoning Georgia to Union forces. Apparently, Hood hoped that if he invaded Tennessee, Sherman would be forced to follow. Sherman, however, had anticipated this strategy and had sent Major General George H. Thomas to Nashville to deal with Hood. With Georgia cleared of the Confederate army, Sherman, facing only scattered cavalry, was free to move south.
