Pemberton. Capture of the Mississippi River town was critical to Union control of the strategic river. Vicksburg was located on a high river bluff defended with artillery, and Pemberton's men had constructed a series of fortifications in an 8-mile arc surrounding the city on the landward side.

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.

Battle - Nashville - Nashville, Tennessee

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

After his march to the sea, Maj. Gen. William T. Sherman headed north in early 1865 to unite with Lt. Gen. Ulysses S. Grant's army in Virginia. Only Confederate Gen.
