No. 30, is that you?

At the turn of the 20th Century, the U.S. Army fielded an impressive array of “disappearing” guns along the American seacoast and few remain. In all, the Army would order some 75 “super heavy” 12-inch disappearing guns, 128 slightly smaller 10-inch guns on similar mounts, 64 8-inch disappearing guns, and the most common type: 152 assorted 6-inch models.

Of the Army’s mixed bag of 419 disappearing guns in various sizes, just four survive in the U.S. today still mounted on disappearing carriages. Two 10-inch guns are currently located at Battery Worth at Fort Casey on Whidbey Island, Washington, and a pair of remaining 6-inch “sister” guns are installed at two locations 2,200 miles apart– one at Battery Chamberlin on the Presidio in San Francisco and the other at Battery Cooper on Fort Pickens near Pensacola, Florida.

I recently visited with the latter and delved into its strange history.

I present to you, a 6-inch rapid-fire rifled gun, Model of 1905, Serial No. 30, on Disappearing Carriage, Model of 1903, located at Battery Cooper near Fort Pickens on Santa Rosa Island in West Florida, just a few miles off Pensacola Beach. Once common, it is one of just two still in existence in the country in its original format.

What is a Rodman?

Ever seen that comical ‘cannon’ that the circus performers shoot acrobats out of? Well, if you were to make a real one out of cast iron, you would have a Rodman. Thomas Jackson Rodman was a Union artillery officer and engineer who came up with a radically different way of making large guns. Until 1861, most large cannon were cast in one huge block of iron and then drilled out. This made the gun prone to developing cracks that could (and did) break apart the entire gun over time. Rodman invented a method of hollow casting the gun in layers using water constantly pumped over the metal to cool it. This made large and strong cannon that dwarfed the older cast guns. They are identified by thier characteristic coke-bottle shape and flat cascabels.

They were the Rodmans…
