Battering-Train, a train of artillery used solely for besieging a strong place, inclusive of mortars and howitzers: all heavy 24, 18, and 12 pounders, come under this denomination; as likewise the 13, 10, and 8 inch mortars and howitzers.
Battering-Ram. See the article [Ram].
BATTERIE de Tambour, a French beat of the drum similar to the general in the British service.
Batterie en roüage, Fr. is used to dismount the enemy’s cannon.
Batterie par camarades, Fr. the discharge of several pieces of ordnance together, directed at one object or place.
BATTERY, in military affairs, implies any place where cannon or mortars are mounted, either to attack the forces of the enemy, or to batter a fortification: hence batteries have various names, agreeably to the purposes they are designed for.
Gun-Battery, is a defence made of earth faced with green sods or fascines, and sometimes made of gabions filled with earth: it consists of a breast-work parapet, or epaulement, of 18 or 20 feet thick at top, and of 22 or 24 at the foundation; of a ditch 12 feet broad at the bottom, and 18 at the top, and 7 feet deep. They must be 7¹⁄₂ feet high. The embrasures are 2 feet wide within, and 9 without, sloping a little downwards, to depress the metal on occasion. The distance from the centre of one embrasure to that of the other is 18 feet; that is, the guns are placed at 18 feet distance from each other; consequently the merlons (or that part of solid earth between the embrasures) at 16 feet within, and 7 without. The genouilliers (or part of the parapet which covers the carriage of the gun) are generally made 2¹⁄₂ feet high from the platform to the opening of the embrasures; though this height ought to be regulated according to the semi-diameter of the wheels of the carriage, or the calibre of the gun. The platforms are a kind of wooden floors, made to prevent the cannon from sinking into the ground, and to render the working of the guns more easy; and are, strictly speaking, a part of the battery. They are composed of 5 sleepers, or joists of wood, laid lengthways, the whole length of the intended platform; and to keep them firm in their places, stakes must be driven into the ground on each side: these sleepers are then covered with sound thick planks, laid parallel to the parapet; and at the lower end of the platform, next to the parapet, a piece of timber 6 inches square, called a hurter, is placed, to prevent the wheels from damaging the parapet. Platforms are generally made 18 feet long, 15 feet broad behind, and 9 before, with a slope of about 9 or 10 inches, to prevent the guns from recoiling too much, and for bringing them more easily forward when loaded. The dimensions of the platforms, sleepers, planks, hurters, and nails, ought to be regulated according to the nature of the pieces that are to be mounted.
The powder magazines to serve the batteries ought to be at a convenient distance from the same, as also from each other; the large one, at least 55 feet in the rear of the battery, and the small ones about 25. Sometimes the large magazines are made either to the right or left of the battery, in order to deceive the enemy; they are generally built 5 feet under ground; the sides and roof must be well secured with boards, and covered with earth, clay, or something of a similar substance, to prevent the powder from being fired: they are guarded by centinels. The balls are piled in readiness beside the merlins between the embrasures.
The officers of the artillery ought always to construct their own batteries and platforms, and not the engineers, as is practised in the English service; for certainly none can be so good judges of those things as the artillery officers, whose daily practice it is; consequently they are the properest people to direct the situation and to superintend the making of batteries on all occasions.
Mortar-Battery. This kind of battery differs from a gun-battery, only in having no embrasures. It consists of a parapet of 18 or 20 feet thick, 7¹⁄₂ high in front, and 6 in the rear; of a berm 2¹⁄₂ or 3 feet broad, according to the quality of the earth; of a ditch 24 feet broad at the top, and 20 at the bottom. The beds must be 9 feet long, 6 broad, 8 from each other, and 5 feet from the parapet: they are not to be sloping like the gun platforms, but exactly horizontal. The insides of such batteries are sometimes sunk 2 or 3 feet into the ground, by which they are much sooner made than those of cannon. The powder magazines and piles of shells are placed as is mentioned in the article [Gun-Battery].
