The Athens Double-Barrelled Cannon
Athens, Clarke County, Georgia
Marker Inscription
The Athens Double-Barrelled Cannon. This cannon, the only known one of its kind, was designed by Mr. John Gilleland, a private in the "Mitchell Thunderbolts," an elite "home guard" unit of business and professional men ineligible because of age or disability for service in the Confederate army. Cast in the Athens foundry, it was intended to fire simultaneously two balls connected by a chain which would "mow down the enemy somewhat as a scythe cuts wheat." It failed for lack of a means of firing both barrels at the exact instant. It was tested in a field on the Newton's Bridge road against a target of upright poles. With both balls rammed home and the chain dangling from the twin muzzles, the piece was fired; but the lack of precise simultaneity caused uneven explosion of the propelling charges, which snapped the chain and gave each ball an erratic and unpredictable trajectory. Lacking a workable firing device, the gun was a failure. It was presented to the City of Athens where, for almost a century, it has been preserved as an object of curiosity, and where it performed sturdy service for many years in celebrating political victories. 029-5 GEORGIA HISTORICAL COMMISSION 1957

The Story
Designed by Athens gunsmith John Gilleland, a member of a home-guard unit of men too old or infirm for regular Confederate service, this double-barrelled cannon was meant to fire two chain-linked balls at once to "mow down" advancing enemies. Cast in a local foundry, it failed in testing because the barrels could not be discharged at precisely the same instant, sending the balls on wild, erratic paths. The gun survives in Athens as a beloved curiosity—one of a kind and famously ineffective.
Why it matters
The odd cannon is a folk emblem of Confederate improvisation and the era's inventive desperation, remembered less for battlefield use than as a monument to a gloriously failed idea.
The story behind this marker
AI contextThe era
The Athens double-barrelled cannon is a product of the Civil War as it was experienced far behind the front lines. By the time it was cast in 1862, the war had shattered any illusion of a quick, tidy conflict, and the Confederacy — short on industry, iron, and manpower — was improvising constantly to arm itself. Backyard foundries, converted workshops, and homegrown inventors were part of the war effort in a way that would have been unthinkable in a peacetime army.
Athens in the 1860s was a college town and a place of business and professional men, and it raised its own home-guard companies — units of citizens too old, too young, or too infirm for regular service, who drilled to defend the town if the fighting ever reached it. It was out of exactly this milieu, and this anxiety, that the strange cannon emerged.
It was also an age enchanted by mechanical ingenuity. The mid-nineteenth century believed deeply that a clever device could solve almost any problem, and warfare inspired no end of inventive schemes. The double-barrelled cannon belongs to that hopeful, restless spirit of invention — the same spirit that produced both genuine breakthroughs and gloriously impractical contraptions.
People & events
The gun was the brainchild of John Gilleland, a private in the Mitchell Thunderbolts — the marker describes them as an elite home-guard unit of business and professional men kept out of the regular Confederate army by age or disability. Gilleland's idea was audacious in its simplicity: build a cannon with two barrels that would fire two balls at the same instant, the balls joined by a chain, so that the linked shot would sweep across advancing troops — in the inscription's memorable phrase, to mow down the enemy somewhat as a scythe cuts wheat.
Cast in the Athens foundry, the piece was taken out to a field on the Newton's Bridge road and tested against a row of upright poles standing in for enemy soldiers. Both balls were rammed home, the chain left dangling between the twin muzzles, and the gun was fired.
The result was the whole problem in miniature. The two charges did not ignite at precisely the same instant, so the balls left the barrels unevenly, the chain snapped, and each ball went careening off on its own wild, unpredictable path. Without a way to fire both barrels at the exact same moment, the weapon simply could not do the one thing it was designed to do, and it was judged a failure.
Its place in the American story
The double-barrelled cannon has earned a lasting place in American memory precisely because it did not work. It stands as a folk emblem of Confederate improvisation — the story of a home front trying to invent its way toward a strength it did not otherwise possess.
More broadly, it captures something true about nineteenth-century America's romance with invention. For every device that changed the world, there were countless ingenious near-misses that foundered on some small, stubborn physical reality — here, the impossibility of igniting two charges in perfect unison with the technology at hand. The gun is a monument to the gap between a brilliant idea and a workable one.
And there is a gentle irony in its afterlife. A weapon conceived to devastate an enemy never served that purpose; instead, presented to the City of Athens, it spent years being fired in celebration of political victories, becoming a beloved civic noisemaker. Its fame rests not on destruction but on the good-humored memory of a bold experiment that failed.
If you visit
This is a monument in Athens, and the object at its heart is genuinely one of a kind — the marker calls it the only known cannon of its type. Look at the twin barrels side by side and imagine the chain that was meant to stretch between them; the design's ambition and its fatal flaw are both visible in that shape.
Come ready to be charmed rather than awed. The story here is warm and a little comic — a town's inventive dreamer, a test against a row of poles, a chain snapping, cannonballs flying every which way. It's a piece of history that invites a smile, and a favorite of families and curious travelers passing through the college town.
On an Athens visit, the cannon fits neatly among the city's other landmarks as a short, memorable stop. Read the inscription, note that for nearly a century it was kept simply as an object of curiosity, and you'll understand why locals have long held a soft spot for their magnificently failed war machine.

Cook & Brother Confederate Armory
Athens, GA
When the Civil War cut the Confederacy off from European arms, two recent English immigrants, Ferdinand and Francis Cook, set out to build the weapons the South could no longer buy. They first established their armory in New Orleans, but as Union forces closed in on that port city in 1862 they hauled the precious rifle-making machinery inland to Athens, Georgia. Here, along the Oconee River, their works turned out Enfield-pattern rifles for Confederate soldiers, making it one of the few private armories to supply the Southern war effort.
Ben T. Epps, Georgia's Pioneer Aviator
Athens, GA
A self-taught mechanic and inventor, Ben T. Epps designed, built, and flew the first airplane in Georgia in 1907 — just four years after the Wright brothers. From his Athens shop he built a series of ever-lighter monoplanes, including a 1924 model weighing just 350 pounds and powered by a motorcycle engine, and he opened an airfield here in 1917. He died in 1937 from a crash on takeoff at this very field.
Birthplace of Bill Arp
Lawrenceville, GA
Charles Henry Smith was born in Lawrenceville in 1826, but Georgia came to know him by his pen name, "Bill Arp." A lawyer and Confederate major, he first used the humorous persona in 1861 and spent more than forty years as one of the South's most beloved newspaper humorists and gentle philosophers. His column ran until his death in 1903, softening hard times with wit.
The Capture of Covington
Covington, GA
As the Battle of Atlanta raged to the west in July 1864, Union cavalry armed with rapid-firing Spencer repeaters swept into the undefended town of Covington. In the violence that followed, a resisting citizen and a furloughed Confederate soldier were killed, and the raiders destroyed or carried off supplies useful to the Confederacy before riding on toward Oxford.
