I’ve always found this little Civil War anecdote pretty amusing:
On April 22, 1862, the cannon was fired for the first time. It was a rather spectacular failure.
…
Screaming spectators ducked and covered as the twinned, spinning projectiles plowed through a nearby wood and destroyed a cornfield before the chain connecting the balls broke. One of the cannonballs then collided into and killed a cow; the other demolished the chimney of a nearby home.
The article delves into the entire history of the now slightly famous double-barreled cannon. This is a good story for all you Civil War enthusiasts out there.
