The cannon is a large turret that fires either lead or iron cannonballs. It could cripple an enemy vessel with one direct hit. They were located on British warships, Coloniel warships, and on land as well. Warships took a month to build so the cannons couln't be used until then. On the ship they carried a certian amount of ammunition based on how long the trip would be. The most famous cannon from the Revolutionary War was the Howizter.
Cannon balls came in various sizes and shapes. A normal cannonball was between four and six pounds. A four-pounder was about 3.055 inches in diameter. A six-pounder was about 3.499 inches in diameter.
Some special shots were the chained shot, the barred shot, the grape shot, and the hot shot. The chained shot was two cannonballs attached with a chain that spun in the air and did some serious damage. The barred shot was one cannon ball with a bar of wood in the middle of it. It looked like half a cannonball, then a bar, then the other half of the cannonball. The grape shot was a canvas bag filled with smaller cannonballs, it was very light and fired an extremly long distance. A "hot shot" was a normal iron cannonball that was put in a furnace first and then fired at the enemy. How's that for dangerous?
A chopper knife was used to light the fuse. If a cannon had too much recoil it could actually make a hole in a ship. Cannons were smooth-bored and long as well, this provided a sleek, accurate shot. With some cannons shot, it could fire up to 800 feet! With some others it could only fire a mesely 200 feet. If a land cannon got just the right shot, it could kill a whole group of enemy soldiers. The cannon size ranged from a two-pounder to a fifty-pounder. When a cannon was fired it was angled betwwen zero and fourty-five degrees.
Quick fact: Henry Knox, who Fort Knox was named after actually found a way to turn one heavy four-pounder into three light six-pounders.
