Shiloh National Military Park preserves the American Civil War Shiloh and Corinth battlefields. The main section of the park is in the unincorporated community of Shiloh, about nine miles (14 km) south of Savannah, Tennessee, with additional areas located in the city of Corinth, Mississippi, 23 miles (37 km) southwest of Shiloh and the Parker's Crossroads Battlefield in the city of Parkers Crossroads, Tennessee. The Battle of Shiloh began a six-month struggle for the key railroad junction at Corinth. Afterward, Union forces marched from Pittsburg Landing to take Corinth in a May siege, then withstood an October Confederate counter-attack.
