The XIV Corps was a unit of the United States Army that played a significant role during the American Civil War. Established in 1862, it was part of the Army of the Cumberland and participated in key battles, including the Battle of Chickamauga and the Battle of Missionary Ridge. The corps was known for its effective leadership and strategic maneuvers. After the Civil War, the XIV Corps was reactivated during the Spanish-American War and later served in various capacities, including in the Philippines. The corps was eventually inactivated in 1900, but its legacy remains a notable part of military history.
