Fort Sidney Johnston
(1862 – 1865), Oven Bluff
A CSA heavy-gun river defense on the Tombigbee River, west of Carlton. Built to prevent Union gunboats from ascending the river further inland. Constructed in the fall of 1862 as Oven Bluff Battery, formally named in June 1863. Not abandoned until after the fall of Mobile in April 1865, when its magazines were blown up by the garrison.
