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. 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.

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.
