This project is about the Siege of Vicksburg, Mississippi.
http://en.wikipedia.org/wiki/Siege_of_Vicksburg
The Siege of Vicksburg (May 18 – July 4, 1863) was the final major military action in the Vicksburg Campaign of the American Civil War. In a series of maneuvers, Union Maj. Gen. Ulysses S. Grant and his Army of the Tennessee crossed the Mississippi River and drove the Confederate Army of Vicksburg led by Lt. Gen. John C. Pemberton into the defensive lines surrounding the fortress city of Vicksburg, Mississippi.
Vicksburg was the last major Confederate stronghold on the Mississippi River; therefore, capturing it completed the second part of the Northern strategy, the Anaconda Plan.
When two major assaults (May 19 and 22, 1863) against the Confederate fortifications were repulsed with heavy casualties, Grant decided to besiege the city beginning on May 25. With no reinforcement, supplies nearly gone, and after holding out for more than forty days, the garrison finally surrendered on July 4. This action (combined with the surrender of Port Hudson to Maj. Gen. Nathaniel P. Banks on July 9) yielded command of the Mississippi River to the Union forces, who would hold it for the rest of the conflict.
The Confederate surrender following the siege at Vicksburg is sometimes considered, when combined with Gen. Robert E. Lee's defeat at Gettysburg by Maj. Gen. George G. Meade the previous day, the turning point of the war. It cut off the states of Arkansas, Louisiana, and Texas from the rest of the Confederacy, as well as communication with Confederate forces in the Trans-Mississippi Department for the remainder of the war.
Background[edit] Further information: Vicksburg Campaign
After crossing the Mississippi River south of Vicksburg at Bruinsburg and driving northeast, Grant won battles at Port Gibson and Raymond and captured Jackson, the Mississippi state capital on May 14, 1863, forcing Pemberton to withdraw westward. Attempts to stop the Union advance at Champion Hill and Big Black River Bridge were unsuccessful. Pemberton knew that the corps under Maj. Gen. William T. Sherman was preparing to flank him from the north; he had no choice but to withdraw or be outflanked. Pemberton burned the bridges over the Big Black River and took everything edible in his path, both animal and plant, as he retreated to the well-fortified city of Vicksburg.[5]
The Confederates evacuated Hayne's Bluff, which was occupied by Sherman's cavalry on May 19, and Union steamboats no longer had to run the guns of Vicksburg, now being able to dock by the dozens up the Yazoo River. Grant could now receive supplies more directly than by the previous route, which ran through Louisiana, over the river crossing at Grand Gulf and Bruinsburg, then back up north.[5]
Over three quarters of Pemberton's army had been lost in the two preceding battles and many in Vicksburg expected General Joseph E. Johnston, in command of the Confederate Department of the West, to relieve the city—which he never did. Large masses of Union troops were on the march to invest the city, repairing the burnt bridges over the Big Black River; which Grant's forces crossed on May 18. Johnston sent a note to his general, Pemberton, asking him to sacrifice the city and save his troops, something Pemberton would not do. (Pemberton, a Northerner by birth, was probably influenced by his fear of public condemnation if he abandoned Vicksburg.)[6]
Opposing forces and the defenses of Vicksburg
As the Union forces approached Vicksburg, Pemberton could put only 18,500 troops in his lines. Grant had over 35,000, with more on the way. However, Pemberton had the advantage of terrain and fortifications that made his defense nearly impregnable. The defensive line around Vicksburg ran approximately 6.5 miles, based on terrain of varying elevations that included hills and knobs with steep angles for an attacker to ascend under fire. The perimeter included many gun pits, forts, trenches, redoubts, and lunettes. The major fortifications of the line included Fort Hill, on a high bluff north of the city; the Stockade Redan, dominating the approach to the city on Graveyard Road from the northeast; the 3rd Louisiana Redan; the Great Redoubt; the Railroad Redoubt, protecting the gap for the railroad line entering the city; the Square Fort (Fort Garrott); a salient along the Hall's Ferry Road; and the South Fort.[8]
Maj. Gen. Ulysses S. Grant's Union Army of the Tennessee brought three corps to the battle: the XIII Corps, under Maj. Gen. John A. McClernand; the XV Corps, under Maj. Gen. William T. Sherman; and the XVII Corps, under Maj. Gen. James B. McPherson.
Lt. Gen. John C. Pemberton's Confederate Army of Mississippi inside the Vicksburg line consisted of four divisions, under Maj. Gens. Carter L. Stevenson, John H. Forney, Martin L. Smith, and John S. Bowen.
Surrender and aftermath
Further information: Vicksburg Campaign Aftermath
On July 3, Pemberton sent a note to Grant, who, as at Fort Donelson, first demanded unconditional surrender. But Grant reconsidered, not wanting to feed 30,000 hungry Confederates in Union prison camps, and offered to parole all prisoners. Considering their destitute state, dejected and starving, he never expected them to fight again; he hoped they would carry home the stigma of defeat to the rest of the Confederacy. In any event, it would have occupied his army and taken months to ship that many prisoners north.[38] Most of the men who were paroled on July 6 were exchanged and received back into the Confederate Army on August 4, 1863, at Mobile Harbor, Alabama. They were back in Chattanooga, Tennessee, by September and some fought in the Battles for Chattanooga in November and against Sherman's invasion of Georgia in May 1864. The Confederate government protested the validity of the paroles on technical grounds and the issue was referred to Grant who, in April 1864, was general in chief of the Army. The dispute effectively ended all further prisoner exchanges during the war except for hardship cases.[39]
Surrender was formalized by an old oak tree, "made historical by the event." In his Personal Memoirs, Grant described the fate of this luckless tree:
It was but a short time before the last vestige of its body, root and limb had disappeared, the fragments taken as trophies. Since then the same tree has furnished as many cords of wood, in the shape of trophies, as the 'True Cross'.[40]
The surrender was finalized on July 4, Independence Day, a day Pemberton had hoped would bring more sympathetic terms from the United States. Although the Vicksburg Campaign continued with some minor actions, the fortress city had fallen and, with the surrender of Port Hudson on July 9, the Mississippi River was firmly in Union hands and the Confederacy split in two. President Lincoln famously announced, "The Father of Waters again goes unvexed to the sea."[41]
Union casualties for the battle and siege of Vicksburg were 4,835; Confederate were 32,697 (29,495 surrendered).[4] The full campaign, since March 29, claimed 10,142 Union and 9,091 Confederate killed and wounded. In addition to his surrendered men, Pemberton turned over to Grant 172 cannons and 50,000 rifles.[42]
Legacy
The works around Vicksburg are now maintained by the National Park Service as part of Vicksburg National Military Park.
A Guide to America's Greatest Historic Places
"...the decisive Civil War campaign in the West that gave the Union control of the Mississippi River and divided the Confederacy in two. Strategically situated on high bluffs overlooking the Mississippi, Vicksburg, with its almost impregnable defenses, was known as the Gibraltar of the Confederacy and was the key link in a chain of Confederate fortifications extending from Louisville, Kentucky, to New Orleans, Louisiana. Its capture was considered essential to the Union. After Federal attempts to seize Vicksburg by land and amphibious assault failed in 1862, General Ulysses S. Grant, on May 18, 1863, launched a campaign to take the stronghold by siege. After 47 days the beleaguered city, defended by Confederates under General John C. Pemberton, surrendered on July 4. Today remains of 9 major Confederate forts, 13 Union approaches, miles of breastworks, gun emplacements, and rifle pits, as well as 1,600 monuments marking the positions of the armies, are preserved. About 2 miles north of town is the Vicksburg National Cemetery, where 17,912 soldiers are buried."
