Advance Redoubt was built to assist Fort Barrancas (700 yards south) in protecting the Navy Yard from overland assault. Although Redoubt was begun in 1845 construction dragged on for almost fifteen years. It is unique among the early American forts at Pensacola in being designed solely for resisting a land-based assault.
Advance Redoubt was only manned during the Civil War. At the conclusion of the Civil War it became evident that the masonry forts could not stand up to the fire of modern rifle artillery and were therefore rendered obsolete.
