Document 3: Tennessee: Many major battles of the American Civil War were fought in Tennessee—most of them Union victories. Ulysses S. Grant and the U.S. Navy captured control of the Cumberland and Tennessee rivers in February 1862. They held off the Confederate counterattack at Shiloh in April. Memphis fell to the Union in June, following a naval battle on the Mississippi River in front of the city. The Capture of Memphis and Nashville gave the Union control of the western and middle sections; this control was confirmed at the Battle of Murfreesboro in early January 1863 and by the subsequent Tullahoma Campaign.
Document 4: Battle of Shiloh: The Battle of Shiloh, also known as the Battle of Pittsburg Landing, was a major battle in the Western Theater of the American Civil War, fought April 6 -- 7, 1862, in southwestern Tennessee. A Union force known as the Army of the Tennessee under Major General Ulysses S. Grant had moved via the Tennessee River deep into Tennessee and was encamped principally at Pittsburg Landing, Tennessee on the west bank of that river, where the Confederate Army of Mississippi, under General Albert Sidney Johnston and second - in - command P.G.T. Beauregard, launched a surprise attack on Grant's army from its base in Corinth, Mississippi. Johnston was mortally wounded during the fighting; Beauregard, who thus succeeded to command of the army, decided against pressing the attack late in the evening. Overnight Grant was reinforced by one of his own divisions stationed further north and was joined by three divisions from another Union army under Maj. Gen. Don Carlos Buell. This allowed them to launch an unexpected counterattack the next morning which completely reversed the Confederate gains of the previous day.

Grant became famous around the nation after capturing Fort Donelson in February 1862 and was promoted to Major General by President Abraham Lincoln. After a series of decisive yet costly battles and victories at Shiloh, Vicksburg, and Chattanooga, Grant was promoted to Lieutenant General by President Lincoln in 1864 and given charge of all the Union Armies.

Document 12: Vicksburg campaign: The city had been under Union naval attack before. Admiral David Farragut moved up the river after his capture of New Orleans and on May 18, 1862, demanded the surrender of Vicksburg. Farragut had insufficient troops to force the issue, and he moved back to New Orleans. He returned with a flotilla in June 1862, but their attempts (June 26 -- 28) to bombard the fortress into surrender failed. They shelled Vicksburg throughout July and fought some minor battles with a few Confederate vessels in the area, but their forces were insufficient to attempt a landing, and they abandoned attempts to force the surrender of the city. Farragut investigated the possibility of bypassing the fortified cliffs by digging a canal across the neck of the river's bend, the De Soto Peninsula. On June 28, Brig. Gen. Thomas Williams, attached to Farragut's command, began digging work on the canal by employing local laborers and some soldiers. Many of the men fell victim to tropical diseases and heat exhaustion, and the work was abandoned by July 24. (Williams was killed two weeks later in the Battle of Baton Rouge).
