In the 1770s, cannon operation worked as follows: each cannon would be manned by two gunners, six soldiers, and four officers of artillery. The right gunner was to prime the piece and load it with powder, and the left gunner would fetch the powder from the magazine and be ready to fire the cannon at the officer's command. On each side of the cannon, three soldiers stood, to ram and sponge the cannon, and hold the ladle. The second soldier on the left was tasked with providing 50 bullets.<ref name="EB1771">{{cite book|title=Encyclopædia Britannica|year=1771|publisher=[[Encyclopædia Britannica, Inc.]]|location=Edinburgh|chapter=Gunnery}}</ref>

Before loading, the cannon would be cleaned with a wet sponge to extinguish any smouldering material from the last shot. Fresh powder could be set off prematurely by lingering ignition sources. The powder was added, followed by wadding of paper or hay, and the ball was placed in and rammed down. After ramming, the cannon would be aimed with the elevation set using a quadrant and a [[plumb-bob|plummet]]. At 45 degrees, the ball had the utmost range: about ten times the gun's level range. Any angle above a horizontal line was called random-shot. Wet sponges were used to cool the pieces every ten or twelve rounds.<ref name="EB1771"/>

During the [[Napoleonic Wars]], a British gun team consisted of five gunners to aim it, clean the bore with a damp sponge to quench any remaining embers before a fresh charge was introduced, and another to load the gun with a bag of powder and then the projectile. The fourth gunner pressed his thumb on the vent hole, to prevent a draught that might fan a flame. The charge loaded, the fourth would prick the [[bagged charge]] through the vent hole, and fill the vent with powder. On command, the fifth gunner would fire the piece with a [[slow match]].<ref>{{cite book|last=Holmes|first=Richard|title=Redcoat: the British Soldier in the age of Horse and Musket|year=2002|publisher=[[W.

When a cannon had to be abandoned such as in a retreat or surrender, the touch hole of the cannon would be plugged flush with an iron spike, disabling the cannon (at least until metal boring tools could be used to remove the plug). This was called "spiking".

A gun was said to be ''honeycombed'' when the surface of the bore had cavities, or holes in it,<ref>Griffiths, ''The Artillerist's Manual'', 53.</ref> caused by corrosion or casting defects.
