In hindsight, this failed Confederate breech-loading gun may have been a bit ahead of its time (or improved technology)

The road to innovation is lined, shall we say, with disappointments.

A double-barreled cannon on outdoor display in Athens, Ga., is one such example. Its inventor hoped to convince the Confederate army that the two rounds, joined by a chain, would mow down infantry and cause chaos.

It did cause chaos. Test-fired in April 1862 in the early months of the Civil War, the gun turned out to be a flop. On one try, the chain holding the two rounds broke -- with one ball hitting a chimney and another killing a cow, according to observers. Another firing resulted in the rounds going off-center and plowing “up about an acre of ground, tore up a cornfield, mowed down saplings, and then the chain broke, the two balls going in different directions.”

About a year later and 140 miles to the southwest, innovators at the Columbus Iron Works on the banks of the Chattahoochee River were experimenting with another relative oddity at the time: breech-loading artillery.

Manufacturers in Europe were trying their hand with such technology, including production of the Whitworth, an English rifled gun that saw limited use during the Civil War. Benefits of such guns included protection for the crew by being behind the weapon, accuracy of fire and faster reloading. Southern breech-loading guns included the Williams and Hughes models.

Designers and craftsmen at the Columbus Iron Works, a large war materials, steam engine, iron cladding and artillery manufacturer for the South, decided to build and test a breech loader.

According to its history, the Columbus piece was designed by engineer and steamboat Capt. W.J. McAlister and Freeman C. Stewart, who worked for the iron works, which was then under command of the Rebel navy.

Prior to the war, some 200 steamboats traveled between Columbus south and the river’s exit in the Florida Panhandle, carrying cotton, crops and other items. Like other captains, McAlister lived near the riverfront and main wharf.

The barrel was fashioned from the wheel shaft of the steamer John C. Calhoun, which had its own misfortunate history. In 1860, its boilers exploded and the mail vessel caught fire, sinking near Ridleyville, Fla. At least one man died and others suffered horrible burns.

A 1978 article in the Columbus Ledger-Enquirer newspaper gave a brief description of how McAlister and Stewart fared in 1863.

The lathe work on the gun was done by Jacob G. Burrus. His sibling, George, paid a visit to the site, which was close to a naval yard.

"On a visit to my brother at the Columbus Iron Works, I found him engaged at the lathe turning the gun. When completed, it was tested three times, but the recoil broke the stirrup through which the breech screws passed for holding the breech plug in place.

"It was finally pronounced a failure. The federal raiders broke off a trunnion to prevent its further use. But it did service as a corner post at Springer's corner."

At this time in their development, breech loaders were fickle and presented some challenges.

An article in Wikipedia says: “The major problem to be solved with breech-loading artillery was obturation: the sealing of the breech after firing to ensure that none of the gases generated by the burning of the propellant (initially gunpowder) escaped rearwards through the breech. This was both a safety issue and one of gun performance – all the propellant gas was needed to accelerate the projectile along the barrel.

“The second problem was speed of operation – how to close the breech before firing and open it after firing as quickly as possible, consistent with safety.”

Eventually, designers came up with ways to create a safe seal and mechanisms that made the technology work. Along, the way they perfected what became forerunners of modern artillery. This Encyclopedia Brittanica article details how changes were made to improve breech-loading artillery, including increasing the strength of certain parts of the barrel to handle the pressure from firing of the weapon.

Today, the iron works gun sits outside the Columbus Museum on Wynnton Road. A sign affixed to its stand calls it “the first breech loading cannon.” It notes that Federal Wilson’s Raiders broke the trunnion when they took the city in April 1865.

The website for an auction house that sold a small replica outlined the concept: “This gun has a simplistic ingenious swiveling strap breech that allows easy access to bore for projectile and powder bag. Strap is then returned to position and screw is turned which closes breech, then friction primer is positioned through breech seal for firing.”

The Columbus Museum’s website says: “The breech-loading cannon is a testament to Columbus residents’ ingenuity and innovation in time of war.” It notes the North did not develop such a weapon, instead using a few imported Whitworths.

What became of the investors of the Columbus breech-loader? I have had no luck on McAlister, but Freeman died in February 1908 at age 77. He was superintendent of the Columbus Iron Works for 30 years after the war.

The W.C. Bradley Co. donated the cannon to the museum in 2016.
