On April 30, 1863, Maj. Gen. Ulysses S. Grant's army crossed the Mississippi River at Bruinsburg, 30 miles south of his objective of Vicksburg. Grant hoped to move east toward the capital at Jackson to block the Confederate army there under Gen. Joseph E. Johnston from reinforcing Vicksburg. Port Gibson, ten miles east of Bruinsburg on the Bayou Pierre River, commanded the best approach routes and was the first Federal objective. A Confederate force there was commanded by Maj. Gen.

On May 12th, 1863, after days of hard marching towards Jackson, Mississippi, Maj. Gen. Ulysses S. Grant fought to secure the crossings of Fourteenmile Creek southwest of Raymond, which would provide a vital water source for his men and animals and serve as a staging area for a strike on the Confederate rail supply line between Clinton and Edwards, Mississippi. Cutting the railroad here would cut off supplies to Grant's ultimate goal, the Mississippi River city of Vicksburg 30 miles to the west. At around…READ MORE

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. After crossing the…READ MORE

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.

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.

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.
