On Independence Day, a day after Gettysburg, federal troops won another great victory far to the west. When General Halleck was called east in July 1862, Ulysses S. Grant resumed command of the Union troops. Grant was one of the most controversial officers in the army. At West Point he had compiled an indifferent record, ranking twenty-first in a class of thirty-nine. During the Mexican War he served well, but when he was later assigned to a lonely post in the West, he took to drink and was forced to resign his commission. Thereafter he was by turns a farmer, a real estate agent, and a clerk in
Vicksburg Campaign Unable to seize Vicksburg by direct assualt, Grant swept to the south, crossed the Mississippi near Port Gibson, and then took Vicksburg from the east.
A leather goods store. In 1861, approaching age forty, he seemed well into a life of frustration and mediocrity.
The war gave him a second chance. Back in service, however, his reputation as a ne’er-do-well and his unmilitary bearing worked against him, as did the heavy casualties suffered by his troops at Shiloh. Yet the fact that he knew how to manage a large army and win battles did not escape Lincoln. According to tradition, when a gossip tried to poison the president against Grant by referring to his drinking, Lincoln retorted that if he knew what brand Grant favored, he would send a barrel of it to some of his other generals. Grant never used alcohol as a substitute for courage. “Old Ulysses,” one of his soldiers said, “he don’t scare worth a damn.”
Grant’s major aim was to capture Vicksburg, a city of tremendous strategic importance. Together with Port Hudson, a bastion north of Baton Rouge, Louisiana, it guarded a 150-mile stretch of the Mississippi. The river between these points was inaccessible to federal gunboats. So long as Vicksburg remained in southern hands, the trans-Mississippi region could send men and supplies to the rest of the Confederacy.
Vicksburg sits on a bluff overlooking a sharp bend in the river. When it proved unapproachable from either the west or the north, Grant devised an audacious scheme for getting at it from the east. He descended the Mississippi from Memphis to a point a few miles north of the city. Then, leaving part of his force behind to create the impression that he planned to attack from the north, he crossed the west bank and slipped quickly southward. Recrossing the river below
Vicksburg, he abandoned his communications and supply lines and struck at Jackson, the capital of Mississippi. In a series of swift engagements his troops captured Jackson, cutting off the army of General John C. Pemberton, defending Vicksburg, from other Confederate units. Turning next on Pemberton, Grant defeated him in two decisive battles, Champion’s Hill and Big Black River, and drove him inside the Vicksburg fortifications. By mid-May the city was under siege. Grant applied relentless pressure, and on July 4 Pemberton surrendered. With Vicksburg in Union hands, federal gunboats could range the entire length of the Mississippi. Texas and Arkansas were for all practical purposes lost to the Confederacy.
Lincoln had disliked Grant’s plan for capturing Vicksburg. Now he generously confessed his error and placed Grant in command of all federal troops west of the Appalachians. Grant promptly took charge of the fighting around Chattanooga, Tennessee, where Confederate advances, beginning with the Battle of Chickamauga (September 19-20), were threatening to develop into a major disaster for the North. Shifting corps commanders and bringing up fresh units, he won another decisive victory at Chattanooga in a series of battles ending on November 25, 1863. This cleared the way for an invasion of Georgia. Suddenly this unkempt, stubby little man, who looked more like a tramp than a general, emerged as the military leader the North had been so desperately seeking. In March 1864 Lincoln summoned him to Washington, named him lieutenant general, and gave him supreme command of the armies of the United States.
