Johnston traveled to Columbia, South Carolina, to begin a virtual retirement. However, as the Confederacy became increasingly concerned about Sherman's March to the Sea across Georgia and then north through the Carolinas, the public clamored for Johnston's return. The general in charge of the Western Theater, P.G.T. Beauregard, was making little progress against the advancing Union force. Political opponents of Jefferson Davis, such as Sen. Louis Wigfall, added to the pressure in Congress. Diarist Mary Chesnut wrote, "We thought this was a struggle for independence. Now it seems it is only a fight between Joe Johnston and Jeff Davis." In January 1865, the Congress passed a law authorizing Robert E. Lee the powers of general in chief, and recommending that Johnston be reinstated as the commander of the Army of Tennessee. Davis immediately appointed Lee to the position, but refused to restore Johnston. In a lengthy unpublished memo, Davis wrote, "My opinion of General Johnston's unfitness for command has ripened slowly and against my inclinations into a conviction so settled that it would be impossible for me again to feel confidence in him as the commander of an army in the field." Vice President Alexander H. Stephens and 17 senators petitioned Lee to use his new authority to appoint Johnston, bypassing Davis, but the general in chief declined. Instead, he recommended the appointment to Davis.
