Historic Blakeley State Park

This aerial view of a portion of the reconstructed battlefield at Historic Blakeley State Park shows Redoubt 4, the heart of the Confederate defenses. Redoubts were temporary fortifications, typically of earthworks, usually located outside a larger main fort. On April 9, 1861, some 2,500 Union soldiers (part of a force of 16,000) attacked the few hundred Confederate defenders (a portion of the 3,500 troops there in total) in the redoubt. The Union scored a decisive victory and then marched on the city of Mobile and took control of it three days later.
