When every lingering scrap of fire had been extinguished inside the barrel they would thrust home the powder bags, then the six-inch shell with its carefully cut fuse protruding from the wooden bung, and the gunner would ram a spike down the touchhole to pierce a canvas powder bag and afterward push a reed filled with more powder down into the punctured bag.
Probably a gunner ranging his piece or testing a rebored touchhole.
The cannon was put on the floor, aiming towards an empty part of the room, three grains of powder were thrust into the touchhole and a match was put to it.
Sharpe was mentally counting the seconds, imagining the gun being pushed back into place and then being sponged out, the gunner's thumb over the touchhole to stop the rush of air forced by the incoming sponge from setting fire to any unexploded powder in the breech.
It was loaded to the muzzle; but just as the pilot was about to apply a red-hot coal to the touchhole, Mr. Fogg said, “Hoist your flag!”
The Sergeant took a length of wire that hung looped on his belt and rammed it through the cannon's touch-hole, piercing the canvas bag beneath, then selected a priming tube, a reed filled with finely milled powder, and slid it down into the powder charge, but leaving a half-inch of the reed protruding above the touchhole.

The powder in the pan would light, and the flame would flash through the touchhole to ignite the larger quantity of powder behind the ball.
He primed his gun, pouring a little powder into the flashpan next to the touchhole, then closed the cover of the pan.
Harper cocked the flintlock that was soldered onto the carronade's touchhole.
