Gun firing
| Морской словарь |
Firing a smoothbore muzzle-loading naval cannon required a great amount of hard work and manpower. the weapon was essentially just a pipe (the barrel), sealed at one end to form a chamber. a wet swab was first thrust down the pipe, to extinguish any embers from a previous firing which might prematurely ignite the next charge. coarse gunpowder was then put into the open end (the “mouth”) either loose with a powder spoon, or pre-wrapped in a cloth or paper cartridge, and pushed down to the chamber with a rammer. a quantity of wadding was then rammed on top of the powder, a cannonball or other form of shot was pushed home on top of the wadding, and another wad was rammed on top of the ball. this not only created a better seal, but also stopped the shot from rolling out due to swaying of the ship. the gun was then “run out,” its crew heaving on the gun tackles until the front of the carriage was hard up against the bulwark, and the barrel protruded through the port. this took the majority of the manpower, since a naval cannon and its carriage could weigh more than two tons and be hard to move if the ship was rolling. a small amount of fine-quality “mealed” gunpowder was then put into the vent (touchhole) and the gun was ready to fire. ignition was initially achieved by thrusting a redhot priming iron (spike) down the vent. this worked well but required an open furnace on the gundeck, creating a fire hazard. the next solution was a slow match applied with a linstock. this also worked well, but progressively eroded the vent, leading to a loss of muzzle velocity due to leakage of propellant gas. in 1697, metal firing tubes were introduced. after removing its paper seal, the tube was placed in the vent and ignited by slow-match or portfire. however, hot and possibly ragged metal tubes lying on the deck after firing were a hazard to the bare feet of gun crews, so they were replaced by goose quills in 1778. however, the quills burned completely on firing, bringing back the problem of vent erosion. finally, in 1790, the problem was effectively solved by introduction of the flintlock.
