More about this marker. The plaque is likely in error. These guns were not part of Fort Marion's armament before the Civil War (the date of manufacture rules that out). The columbiads were part of a batch produced for the Confederacy early in the Civil War.
According to reports, the fort contained only 8-inch howitzers (which are still at the fort today) and 32-pounder smoothbore guns, when recaptured by Federals in March 1862. The Federals may have captured the columbiads elsewhere and moved them to Fort Marion for safe-keeping.
Clearly the cannons were at Fort Marion after the war. However, their use by the Army after the war would be limited. The elevation system would require pre-Civil War carriages. Further, the guns were not constructed in the manner used by the regulation Federal 8-inch guns, and would be suspect when firing full charges.
