Some Southerners suspected in 1864 what we now know—Sherman had not retreated. Rather, he had concluded that only his infantry could effectively break Hood’s lines of supply and had resolved to move almost all of his force to the southwest of the city. The movement began on August 25. One corps was sent back to the Chattahoochee bridgehead to guard the railroad that connected Sherman with the North. The remaining Federal troops pulled out of their trenches and marched away to the west and south. By noon on the 28th, Howard’s Army of the Tennessee had reached Fairburn, a small station on the Atlanta and West Point Railroad, 13 miles southwest of East Point. Later that afternoon, Thomas’ troops occupied Red Oak, on the railroad 5 miles to the northeast. The Northerners spent the rest of the 28th and the 29th destroying the tracks. The rails were torn up, heated, and twisted so that they were useless. Only one railroad, the Macon and Western, running southeast from East Point to Macon, now remained in Confederate hands. Sherman soon moved to cut it. By August 29, Hood had learned of the activities of the Federals at Fairburn. It was clear that the railroad to Macon would be Sherman’s next objective and the Southern commander acted to defend that line. However, he badly misjudged the situation and thought that only two corps of Sherman’s army were to the southwest. Late on August 30, Hood ordered Hardee to take two corps of the Southern army, move against the raiding column, and drive it away. Both armies were soon closing in on Jonesborough, 14 miles below East Point on the Macon railroad. By that evening, advance elements of the Union forces had crossed the Flint River and entrenched a position 1 mile west of Jonesborough. During the night, Hardee’s Southerners moved into the town by rail; by morning they were deploying in front of the Federal line. Hardee had his own corps (temporarily led by Maj. Gen. Patrick R. Cleburne) and Lee’s. It took until mid-afternoon to complete preparations for an attack. The Confederates advanced about 3 p.m., their assault falling mostly on an entrenched salient on the east bank of the Flint held by the Army of the Tennessee. The attack was fierce but uncoordinated and failed to drive back the Northerners. When the fighting ceased that night, the relative positions of the armies were unchanged. Meanwhile, Schofield’s Army of the Ohio had managed to break the Macon railroad near Rough-and-Ready, a small station between Jonesborough and East Point. This movement led Hood to conclude that Sherman’s main force was attacking Atlanta from the south. The Confederate commander, therefore, ordered Lee’s Corps to leave Hardee at Jonesborough and move toward Atlanta to help defend the city. Lee began this movement at 2 a.m. the next morning.
