This is how to fire a Civil War cannon, step-by-step

With ATACMS, MLRS, HIMARs, the M109A6, and the M777, American artillery can and does deliver a huge punch at a distance. Compared to them, Civil War cannons look downright puny.


Don't take that to the bank, though. These old cannon were pretty powerful in their day. The Smithsonian Channel decided to take a look at how to fire a Civil War cannon from start to finish using the Model 1841 12-pound howitzer.

According to Antietam on the Web, the howitzer of the time had a 4.62-inch bore (117 millimeters) and a 53-inch long barrel. It had a range of 1,072 yards – or about the same distance an M40 sniper rifle chambered in 7.62mm NATO can reach out and touch someone.

It had three types of ammo: canister, which was essentially a giant shotgun shell; spherical case shot, which became known as a shrapnel shell; and a common shell, which was your basic impact-fused or time-fused explosive shell.

Without further ado, here's the video from the Smithsonian Channel showing how to fire this cannon, using an authentic replica.
