Fire-masters-mate. His duty is, to aid and assist the chief fire-master, and he should be skilled in every kind of laboratory works.
Fire-pan of a gun, is the receptacle for the priming powder.
Fire-pot, in the military art, a small earthen pot, into which is put a charged grenade, and over that, powder enough to cover the grenade; the whole covered with a piece of parchment, and two pieces of quick match across lighted: it breaks and fires the powder, as also the powder in the grenade, which has no fuze, that its operations may be quicker: it burns all that is near it.
Fire-works, are particular compositions of different sorts, made with sulphur, salt-petre, and charcoal. They are used in war, and on rejoicing days.
Fire-workers, were formerly subordinate to the fire-master and his mate; had afterwards the rank of youngest lieutenants to the regiment of artillery; but now that rank is abolished, and they are all second lieutenants. They were supposed to be well skilled in every kind of laboratory-work, which knowlege is an essential qualification in every officer of that regiment.
Fire-locks, so called from their producing fire of themselves, by the action of the flint and steel; the arms carried by a foot-soldier: they were formerly 3 feet 8 inches in the barrel, and weighed 14lb.; at present the length of the barrel is from 3 feet 3 inches to 3 feet 6 inches and the weight of the piece from 9 to 12lb. British fire-locks carry a leaden bullet of which 29 make 2lb. Its diameter is .550 of an inch, and that of the barrel ¹⁄₅₀th part of the shot. Fire-locks were first made use of in 1690, when matchlocks were universally disused; but when invented we cannot ascertain. A fire-lock is called, by writers of about the middle of the last century, a snaphaan, which being a low Dutch word, seems to indicate its being a Dutch invention. Formerly, both in the manual and platoon exercises, the term fire-lock was always adopted—as shoulder your fire-lock, present your fire-lock—At present a more simple and brief mode of expression prevails as, shoulder arms, carry arms, &c.
FIRING in line. According to regulations, the following principal heads constitute firing in line.
The object of fire against cavalry is to keep them at a distance, and to deter them from the attack; as their movements are rapid, a reserve is always kept up. But when the fire commences against infantry, it cannot be too heavy, nor too quick while it lasts; and should be continued till the enemy is beaten or repulsed. This may not improperly be called offensive fire.
Defensive fire, belongs principally to infantry, when posted on heights, which are to be defended by musquetry. As soldiers generally aim too high, and as fire is of the greatest consequence to troops that are on the defensive, the habitual mode of firing should therefore be rather at a low level of three or four feet than a high one.
On these occasions the men are generally drawn up 3 deep; in which case the front rank may kneel when it can be safely and usefully done; but this is now generally rejected, and the third rank loads for the centre rank, which fires the guns of both centre and rear rank.
