The Battle of Shiloh, also known as the Battle of Pittsburg Landing was a major battle of the American Civil War in the state of Tennessee, which occurred from April 6-7, 1862.
Elements of Confederate General Albert Sidney Johnston Army of the Mississippi attacked Union General Ulysses S. Grant's Army of the Tennessee on the morning of April 6 in a preemptive strike. It was Grant's intention to join up with General Don Carlos Burell's Army of the Tennessee and attack Johnston at Corinth.
Later that day, Johnston was killed and General PGT Bueregard took command of the Confederates. Driving the Federals back to near the Tennessee River, Beuregaurd ceased operations for the night, in order to finished the fight the next day. This allowed Buell to join Grant and allow the Federals to win the battle the next day.
