In mid-May, 1863, after six months of unsuccessful attempts, Maj. Gen. Ulysses S. Grant's Army of the Tennessee finally converged on Vicksburg, defended by a Confederate army under Lt. Gen. John C. Pemberton. Capture of the Mississippi River town was critical to Union control of the strategic river.

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.

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
