General Howard led the march from Atlanta this morning with the right wing and cavalry following the railroad southeast toward Jonesboro. General Slocum with the Twentieth Corps led the left wing off to the east by Decatur and Stone Mountain, toward Madison. These are divergent lines, designed to threaten both Mason and Augusta at the same time, so as to prevent a concentration at our intended destination, Milledgeville, the capital of Georgia, distant southeast about one hundred miles. I allow seven days for each column to reach Milledgeville. I will remain in Atlanta with the Fourteenth Corps, and the rear-guard of the right wing, to complete the loading of the trains, and the destruction of the buildings of Atlanta which could be converted to hostile uses.
