Firing mechanism of Columbus breech loader (Picket photos) |
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.
