cannon was prepared to fire by the loader placing a ball
into the barrel and the spongeman ramming it down into position.
ventsman then covered the touchhole with his thumb, to stop
any premature explosion if any burning particles have been
left by a previous shot.
clear of that danger, the ventsman then pricked the shot's
cartridge, placed a firing tube and looked at the cannon's
the gun was sighted, the firer touched his portfire to the
tube and the cannon fired.
firing, a cannon would have to be moved some two metres
back to its set-up position by its gun crew, armed with
handspikes and ropes.
spongeman would then dip his fleecy ramrod into a bucket
of water and clean out the barrel of the cannon to make
sure there were no sparks to set off the next charge.
