s. The long gun was known for its increased range and improved mobility in comparison to its larger precursors. This allowed the long gun to establish itself as the best form of artillery to pursue an enemy. In informal usage, the length was combined with the weight of shot, yielding terms like "long nines", referring to full-length, 9-pounder guns.

is put in. Once the barrel is clean, the gunpowder is put into the base of the cannon, either loosely or in cloth bags. A piece of cloth or rope is put in after the gunpowder to assure that it stays tightly packed. The cannonball follows and is topped off with a piece of wool or cotton. This secondary piece of cotton helps to keep the cannonball in place and secure with the explosives. Long guns, being extremely heavy when fully loaded and ready to fire, had to be moved into position after being loaded. This typically took the full effort from the group of men attempting to transport it. The cannon is then pushed forward until it is in full contact with the side of the ship, and the barrel is pointed through the

. Once in position, a small hole in the back of the cannon is lined with a small amount of gunpowder. This process is called priming. From there, the cannon operator stood back from the cannon and held a string until the cannon was lined up with the enemy's ship. Once aimed in the right direction, the operator will pull the

Size regulation

Naval long guns, or long nines were originally made in only two sizes, or . This was set by the

Board of Ordnance The Board of Ordnance was a British government body. Established in the Tudor period, it had its headquarters in the Tower of London. Its primary responsibilities were 'to act as custodian of the lands, depots and forts required for the defence ...

in 1703. In the early 1700s, long guns started to dwindle in usage, but came back to prominence in 1761 when the Board of Ordnance changed its primary restriction of the size of long nines. The new protocol for manufacturing long guns included five lengths that ranged from to in length. The size of the gun often depended on the size of the ship that carried it, and how many of the guns the ship was to carry. In 1782, another change was made to the design of the long nine; it could be manufactured at a length of .

used in the naval long guns did not offer as much variety as the size of the gun did. The only ammunition used was a simple nine pound cannonball, called a nine pounder. Nine pounders were the lightest of all cannon ammunition, and therefore allowed long nines to have increased range. This played a large part behind the purpose of the gun, which was to chase and pursue a fleeing enemy ship or fleet.
