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.

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. On August 25, Union infantry beg…READ MORE

Despite a series of defeats in the closing days of November, 1864, Confederate Lieut. Gen. John Bell Hood continued to drag his bloodied Army of Tennessee, approximately 30,000 strong, north towards Nashville. The city was protected by 55,000 Union soldiers, which should have precluded further offensive operations, but Hood was determined and his situation was dire. Hood reached Nashville on December 2nd and staked out a position south of the city, hoping to draw the Union forces into a costly attack. Ulys…READ MORE
