Part 17 of my "Heritage" travel campaign.
I visited the Shiloh National Military Park, located in Hardin County, Tennessee. https://www.nps.gov/shil/index.htm
The Battle of Shiloh, also known as the Battle of Pittsburgh Landing, was a battle in the American Civil War that was fought on April 6th & 7th in 1862. On April 6th, a Union force of about 45,000 (Army of the Tennessee) led by General Ulysses S. Grant, was confronted by a smaller Confederate force of just over 40,000 (Army of Mississippi) led by General Albert S. Johnston, in a surprise attack on Grant's base in Corinth, Mississippi.
Johnston was mortally wounded in the attack and General P.G.T. Beauregard assumed command of the Army of Mississippi.
Beauregard was against a night attack after his Army's victory after the first day, as he wanted his exhausted men to rest and be ready for the next day.
But during the night of the first day, one of Grant's own divisions reinforced his Army, as well as three divisions from the Army of the Ohio, led by General Don Carlos Buell. On April 7th, now with numbers of about 63,000, Union forces launched a surprise counterattack in the morning and erased the previous day's Confederate gains.
The Battle of Shiloh was a Union victory.
Casualties (dead, wounded, captured, missing) from both sides totaled about 23,700 (13,000 Union, 10,700 Confederate).
