Key West in Monroe County, Florida — The American South (South Atlantic)
—Dry Tortugas National Park —
The fort had no guns when Major L.G. Arnold and his 66 artillerymen arrived from Boston, January 19, 1861. As they worked on the first gun mount, a courier from an armed vessel came ashore and demanded surrender to the State of Florida. When Arnold met the messenger, he rushed to his gunport. "Tell your captain," he shouted to the messenger, "I will blow his ship out of the water if he’s not gone in ten minutes!"
The bluff worked. By the time war began in April, Arnold had mounted 68 cannon.
Technically, gunrooms are “casemates.” This fort has 303 of them. A thick wall in front and strong vaulting above protected guns and men from enemy fire. Open backs and overhead vents carried off heat and smoke.
Though designed to deliver the most concentrated firepower of its time, Fort Jackson never received more than 141 guns - a third of its full armament - because of structural failure.
