This would have been deadly if it had worked: In 1862, Confederate private John Gilleland of Georgia’s Mitchell Thunderbolts designed a double-barreled cannon. Gilleland intended that the barrels would fire two balls connected by a chain that would “mow down the enemy somewhat as a scythe cuts wheat.”

Unfortunately he couldn’t devise a way to fire both muzzles at the same instant, so in testing the chain simply snapped and sent both balls off on unpredictable trajectories. The cannon was never used in battle, and today it’s displayed as a curiosity before the city hall in Athens, Ga.
