When Sherman captured Atlanta in early September 1864, he knew that he could not remain there for long. His tenuous supply line ran from Nashville, Tennessee, through Chattanooga, Tennessee, then one hundred miles through mountainous northern Georgia. The army he had just defeated, the Army of Tennessee, was still in the area and its leader, John Bell Hood, swung around Atlanta to try to damage Sherman’s lifeline. Of even greater concern was the Confederate cavalry of General Nathan Bedford Forrest, a brilliant commander who could strike quickly against the railroads and river transports on which Sherman relied.
During the fall, Sherman conceived of a plan to split his enormous army. He sent part of it, commanded by General George Thomas, back toward Nashville to deal with Hood while he prepared to take the rest of the troops across Georgia. Through October, Sherman built up a massive cache of supplies in Atlanta. He then ordered a systematic destruction of the city to prevent the Confederates from recovering anything once the Yankees had abandoned it. By one estimate, nearly 40 percent of the city was ruined. Sherman would apply to the same policy of destruction to the rest of Georgia as he marched to Savannah. Before leaving on November 15, Sherman’s forces had burned the industrial district of Atlanta and left little but a smoking shell.
