Determined to reoccupy the city, Bragg followed the Federals north, brushing with Rosecrans' army at Davis' Cross Roads. While they marched on September 18th, his cavalry and infantry skirmished with Un…READ MORE

Johnston established a four-mile defensive position protecting the Western & Atlantic Railroad west and north of Resaca, where the railroad crossed the Oostanaula River. On May 13th, Sherman tested the Rebel lines, sending forward divisions to skirmish with the Confederates, with little substantive result. On the 14th, the fighting erupted into a full-…READ MORE

Fearing envelopment northwest of Atlanta, Confederate Gen. Joseph E. Johnston withdrew his army to a new defensive position astride Kennesaw Mountain near Marietta. Johnston selected this position in order to protect the Western & Atlantic Railroad, his supply link to Atlanta. Prior to taking up this new line on June 19th, Johnston had pioneers working through the night digging trenches and erecting fortifications, turning Kennesaw into a formidable earthen fortress.

Weary of Gen. Joseph E. Johnston's pattern of retreat through northwest Georgia in the face of Maj. Gen. William T. Sherman's advancing armies, President Jefferson Davis removed him from command of the Army of Tennessee, replacing him with Lieut. Gen. John B. Hood. On July 20th, Hood determined to take the fight to the enemy by setting upon an isolated portion of Sherman's forces in front of Atlanta. Hood's target would be the Union corps of Maj. Gens.

Despite the defeat at Peach Tree Creek, Confederate Lieut. Gen. John Bell Hood still had hopes of driving Maj. Gen. William T. Sherman's Yankees from the outskirts of Atlanta with an offensive blow. On the night of July 21, 1864, Hood ordered Lt. Gen. William J. Hardee's corps to make 15-mile night march and assault the Union left flank east of the city, held by Maj. Gen. James B. McPherson's Army of the Tennessee. Joining the attack with Hardee would be the corps of Maj. Gen. Benjamin Cheatham. Hood attac…READ MORE

By late August 1865, the city of Atlanta was not yet subdued by Maj. Gen. William T. Sherman's armies. A few supply lines remained open to the city supporting the army of Lieut. Gen. John B. Hood encircled there. Union cavalry raids inflicted only superficial damage, quickly repaired by the Confederates. Sherman determined that if he could destroy the Macon & Western and Atlanta & West Point Railroads to the south the Rebel army would be forced to evacuate the city.
