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. T. Beauregard, launched an attack on Grants army from its base in Corinth. Johnston was killed in action during the fighting, Beauregard, who succeeded to command of the army. 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 a counterattack the next morning which completely reversed the Confederate gains of the previous day. On April 6, the first day of the battle, the Confederates struck with the intention of driving the Union defenders away from the river, Johnston hoped to defeat Grants army before the anticipated arrival of General Buells Army of the Ohio. The Confederate battle lines became confused during the fighting, and Grants men instead fell back to the northeast. A Union position on a sunken road, nicknamed the Hornets Nest. Benjamin Prentisss and William H. L. Wallaces divisions, provided critical time for the remainder of the Union line to stabilize under the protection of artillery batteries. Wallace was mortally wounded when the position collapsed, while several regiments from the two divisions were surrounded and surrendered. General Johnston was shot in the leg and bled to death while leading an attack. Beauregard, his second in command, acknowledged how tired the army was from the days exertions, Confederate forces were forced to retreat from the area, ending their hopes of blocking the Union advance into northern Mississippi. Smiths orders were to lead raids intended to capture or damage the railroads in southwestern Tennessee, Brig. Gen. William T. Shermans troops arrived from Paducah, Kentucky, to conduct a similar mission to break the railroads near Eastport, Mississippi. Halleck also ordered Grant to advance his Army of West Tennessee on an invasion up the Tennessee River, Grant left Fort Henry and headed upriver, arriving at Savannah, Tennessee, on March 14, and established his headquarters on the east bank of the river. Grants troops set up camp farther upriver, five divisions at Pittsburg Landing, Tennessee, meanwhile, Hallecks command was enlarged through consolidation of Grants and Buells armies and renamed the Department of the Mississippi. With Buells Army of the Ohio under his command, Halleck ordered Buell to concentrate with Grant at Savannah, Buell began a march with much of his army from Nashville, Tennessee, and headed southwest toward Savannah. The railroad was a supply line connecting the Mississippi River at Memphis, Tennessee to Richmond. Maj. Gen. Ulysses S. Grant developed a reputation during the war for being concerned with his own plans than with those of the enemy
