The Arsenal Academy was a military academy in Columbia, South Carolina, originally established in 1842 as an independent school by the state of South Carolina. In 1845, the academy became a component of the South Carolina Military Academy (now The Citadel), in which first year cadets underwent their initial year of training before completing their studies at the larger Citadel Academy in Charleston, South Carolina. The school was burned by Sherman's forces in 1865 and never reopened.
