A MMUNITION—For small arms, in the British service, is generally packed in half barrels, each containing 1000 musquet, or 1500 carbine cartridges. An ammunition waggon will carry 20 of these barrels, and an ammunition cart 12 of them: their weight nearly 1 cwt. each.

The cartouch boxes of the infantry are made of so many different shapes and sizes, that it is impossible to say exactly what ammunition they will contain; but most of them can carry 60 rounds. See the word Cartridges; and for Artillery Ammunition, see the word Artillery, for the field, for the siege, and the defence of a fortified place.

The French pack all their ammunition in wagons without either boxes or barrels, by means of partitions of wood. Their 12 Pr. and 8 Pr. waggons will contain each 14,000 musquet cartridges, but their 4 Pr. waggons will contain only 12,000 each.

ARTILLERY.—The proportion of artillery and ammunition necessary to accompany an army in the field, to lay siege to a fortified place, or to defend one, must depend upon so many circumstances, that it is almost impossible, in a small work of this kind, to lay down any satisfactory rules as guides on the subject: the following principles are, however, drawn from the best authorities:

1st. Artillery for the Field.

Field Artillery is divided into Battalion Guns, Artillery of the Park, and Horse Artillery.

The Battalion Guns include all the light pieces attached to regiments of the line, which they accompany in all manœuvres, to cover and support them.

The following natures of field ordnance are attached to battalions of infantry, by different powers in Europe:

French two   4   Prs.   per   battalion.
English two 6
Danes two 3
Austrians three 6
Prussians two 6 Prs. to a battalion in the first line.
”   two 3 Prs. to a battalion in the second line.
Hanoverians two 3 Prs. per battalion.

The Artillery of the Park is composed of all natures of field ordnance. It is destined to form batteries of position; that is to say, to occupy advantageous situations, from which the greatest effect may be produced, in supporting the general movements of an army, without following it, like the battalion guns, through all the detail of its manœuvres. The park of artillery attached to an army in the field generally consists of twice as many pieces of different natures, varied according to the country in which it is to act, as there are battalions in the army. Gribauvale proposes the following proportion between the different natures of artillery for the park or reserve, viz. ⅖ of 12 Prs. ⅖ of 8 Prs. and ⅗ of 4 Prs. or reserve for battalion guns. In a difficult country he says, it may be ¼ of 12 Prs. ½ of 8 Prs. and ¼ of 4 Prs. and for every 100 pieces of cannon he allots 4 Howitzers; but this proportion of Howitzers is much smaller than what is generally given.

Horse Artillery.—The French horse artillery consists of 8 Prs. and 6 inch Howitzers.

The English of light 12 Prs. light 6 Prs. and light 5½ inch Howitzers.

The Austrian and Prussian horse artillery have 6 Prs. and 5½ inch Howitzers.

Ammunition for Field Artillery.

A proportion of Ammunition and Stores for each Nature of Field Ordnance, viz. 1 Med. 12 Pr.[1]—1 heavy 6 Pr.—2 light 6 Prs. as they are always attached to Battalions of Infantry—and one 5½inch Howitzer; according to the British Service.

  Has no limber boxes,[2] but has two waggons attached to it,
and the ammunition and stores divided between them.
 
 6 Pr.

must have a waggon attached to it, to carry the remainder. But two 6
pounders, attached to a battalion, have only one waggon between them.

This table contains, beside the proportion of ordnance with each army, also the quantity of ammunition with each piece of ordnance, and the number of rounds of musquet ammunition carried for the infantry; for each waggon in the French Service, having its particular allotment of ammunition and stores, it needs but to know the number of waggons of each description, to ascertain the quantity of ammunition and stores with an army. The following is the number of waggons usually attached to each piece of field ordnance in the French Service, and the quantity of ammunition carried with each.

Of the Movements and Positions of Field Artillery.

Battalion Guns.—The following are the usual positions taken by battalion guns, in the most essential manœuvres of the battalion to which they are attached; but the established regulations for the movements of the infantry in the British Service, take so little notice of the relative situations for the artillery attached to it, that there is no authority for a guide on the subject. In review, both guns are to be placed, when, in line, on the right of the regiment; unlimbered and prepared for action. The guns 10 yards apart, and the left gun 10 yards from the right of the grenadiers. Nos. 7 and 8 dress in line with the front rank of the regiment. The officer, at open order, will be in front of the interval between his guns, and in line with the officers of the regiment. When the regiment breaks into column, the guns will be limbered up and wheel by pairs to the left: the men form the line of march, and the officer marches round in front of the guns. In the review of a single battalion, it is usual after marching round the second time, for one of the guns to go to the rear, and fall in at the rear of the column. Upon the regiment wheeling on the left into line, the guns, if separated, will be unlimbered to the right, but if they are both upon the right, they must be wheeled to the right, and then unlimbered; and afterwards run up by hand, as thereby they do not interfere with the just formation of the line, by obstructing the view of the pivots.

The usual method by which the guns take part in the firings while in line, is by two discharges from each piece, previous to the firing of the regiment; but this is usually regulated by the commanding officer, before the review. Though the guns when in line with a regiment in review, always remain in the intervals; in other situations of more consequence, every favorable spot which presents itself, from which the enemy can be more effectually annoyed, should be taken advantage of. In column, if advancing, the guns must be in front; if retreating, in the rear of the column. If in open column of more than one battalion, the guns in the center must be between the divisions, and when the column is closed, these guns must move to the outward flank of that division of the column, which leads the regiment to which they are attached. In changing front, or in forming the line from column, should the guns be on that flank of the battalion on which the new line is to be formed, they will commence firing to cover the formation.

In retiring by alternate wings or divisions, the guns must be always with that body nearest the enemy. That is, they will not retire with the first half, but will remain in their position till the second half retires; and will then only retire to the flanks of the first half; and when it retires again, the guns will retire likewise, but only as far as the second half, and so on.

When in hollow square, the guns will be placed at the weakest angles, and the limbers in the center of the square. In passing a bridge or defile in front, the guns will be the first to pass; unless from any particular position they can more effectually enfilade the defilé; and thereby better open the passage for the infantry. But in retiring through a defilé, the guns will remain to the last, to cover the retreat.

General Rule.—With very few variations, the guns should attend in all the movements of the battalion, that division of it, to which they are particularly attached; and every attention should be paid in thus adapting the movements of the guns to those of the regiment, that they be not entangled with the divisions of the line, and never so placed as to obstruct the view of the pivots, and thereby the just formation of the line; but should always seek those positions, from which the enemy can be most annoyed, and the troops to which they are attached, protected.

If at any time the battalion guns of several regiments should be united and formed into brigades, their movements will then be the same as those for the artillery of the park.

Artillery of the Park.

The artillery of the park is generally divided into brigades of 4 or 6 pieces, and a reserve, according to the force and extent of the front of an army. The reserve must be composed of about ⅙ of the park, and must be placed behind the first line. If the front of the army be extensive, the reserve must be divided.

The following are the principal rules for the movements and positions of the brigades of artillery: they are mostly translated from the Aide Memoire, a new military work.

In a defensive position, the guns of the largest caliber must be posted in those points, from whence the enemy can be discovered at the greatest distance, and from which may be seen the whole extent of his front.

In an offensive position, the weakest points of the line must be strengthened by the largest calibers; and the most distant from the enemy: those heights on which the army in advancing may rest its flanks, must be secured by them, and from which the enemy may be fired upon obliquely.

The guns should be placed as much as possible under cover; this is easily done upon heights, by keeping them so far back that the muzzles are only to be seen over them: by proper attention many situations may be found of which advantage may be taken for this purpose, such as banks, ditches, &c. every where to be met with.

A BATTERY in the field should never be discovered by the enemy till the very moment it is to open. The guns may be masked by being a little retired; or by being covered by troops, particularly cavalry.

To enable the commanding officer of artillery to choose the proper positions for his field batteries, he should of course be made acquainted, with the effect intended to be produced; with the troops that are to be supported; and with the points that are to be attacked; that he may place his artillery so as to support, but not incommode the infantry; nor take up such situations with his guns, as would be more advantageously occupied by the line. That he may not place his batteries too soon, nor too much exposed; that he may cover his front and his flanks, by taking advantage of the ground; and that he may not venture too far out of the protection of the troops, unless some very decided effect is to be obtained thereby.

The guns must be so placed as to produce a cross fire upon the position of the enemy, and upon all the ground which he must pass over in an attack.

They must be separated into many small batteries, to divide the fire of the enemy; while the fire from all these batteries, may at any time be united to produce a decided effect against any particular points.

These points are the débouchés of the enemy, the heads of their columns, and the weakest points in the front. In an attack of the enemy’s position, the cross fire of the guns must become direct, before it can impede the advance of the troops; and must annoy the enemy’s positions nearest to the point attacked, when it is no longer safe to continue the fire upon that point itself.

The shot from artillery should always take an enemy in the direction of its greatest dimension; it should therefore take a line obliquely or in flank, but a column in front.

The artillery should never be placed in such a situation, that it can be taken by an enemy’s battery obliquely, or in flank, or in the rear; unless a position under these circumstances, offers every prospect of producing a most decided effect, before the guns can be destroyed or placed hors de combat.

The most elevated positions are not the best for artillery, the greatest effects may be produced from a height of 30 or 40 yards at the distance of about 600 and about 16 yards of height to 200 of distance.

Positions in the rear of the line are bad for artillery, because they alarm the troops, and offer a double object to the fire of the enemy.

Positions which are not likely to be shifted; but from whence an effect may be produced during the whole of an action, are to be preferred; and in such positions a low breast work of 2 or 3 feet high may be thrown up, to cover the carriages.

Artillery should never fire against artillery, unless the enemy’s troops are covered, and his artillery exposed; or unless your troops suffer more from the fire of his guns, than his troops do from yours.

Never abandon your guns till the last extremity. The last discharges are the most destructive; they may perhaps be your salvation, and crown you with glory.

The parks of artillery in Great Britain are composed of the following ordnance; 4 medium 12 pounders; 4 desaguliers 6 pounders; and 4 light 5½ inch howitzers.

The following is the proposed line of march for the three Brigades when acting with different Columns of Troops, as settled, in 1798.

2d. Artillery and Ammunition for a Siege.

Necessary considerations in forming an estimate for this service.

The force, situation, and condition of the place to be besieged; whether it be susceptible of more than one attack; whether lines of circumvallation or countervallation will be necessary; whether it be situated upon a height, upon a rocky soil, upon good ground, or in a marsh; whether divided by a river, or in the neighborhood of one; whether the river will admit of forming inundations; its size and depth; whether the place be near a wood, and whether that wood can supply stuff for fascines, gabions, &c.; whether it be situated near any other place where a depot can be formed to supply stores for the siege. Each of these circumstances will make a very considerable difference in proportioning the stores, &c. for a siege. More artillery will be required for a place susceptible of two attacks, than for the place which only admits of one. For this last there must be fewer pieces of ordnance, but more ammunition for each piece. In case of lines being necessary, a great quantity of intrenching tools will be required, and a numerous field train of artillery. In case of being master of any garrison in the neighborhood of the besieged town, from whence supplies can readily be drawn, this must be regarded as a second park: and too great a quantity of stores need not be brought at once before the besieged place. The number of batteries to be opened before the place must determine the number of pieces of ordnance; and on the quantity of ordnance must depend the proportion of every species of stores for the service of the artillery.

There must be a battery to enfilade every face of the work to be besieged, that can in any way annoy the besiegers in their approaches. These batteries, at least that part of them to be allotted for guns, need not be much longer than the breadth of the rampart to be enfiladed, and will not therefore hold more than 5 or 6 heavy guns; which, with two more to enfilade the opposite branch of the covert way, will give the number of guns for each ricochet battery. As the breaching batteries, from their situation, effectually mask the fire of the first or ricochet batteries, the same artillery generally serves for both. Having thus ascertained the number of heavy guns, the rest of the ordnance will bear the following proportion to them:

The fewer natures of ordnance which compose the demand the better, as a great deal of the confusion may be prevented, which arises from various natures of ammunition and stores being brought together.

The Carriages for the Ordnance are generally as follows:

Ammunition for the Ordnance.

The following proportion of artillery and ammunition was demanded by a very able officer, for the intended siege of Lisle, in 1794, which place was thought susceptible of two attacks.

Of the Arrangement of Artillery at a Siege.

The first arrangement of the artillery at a siege is to the different batteries raised near the first parallel, to enfilade the faces of the work on the front attacked, which fire on the approaches. If these first batteries be favorably situated, the artillery may be continued in them nearly the whole of the siege; and will save the erection of any other gun batteries, till the besiegers arrive on the crest of the glacis. It however frequently happens, from local circumstances, that the besiegers cannot avail themselves of the most advantageous situations for the first batteries. There are four situations from which the defences of any face may be destroyed; but not from all with equal facility. The best position for the first batteries, is perpendicular to the prolongation of the face of the work to be enfiladed. If this position cannot be attained, the next that presents itself is, on that side of the prolongation which takes the face in reverse; and under as small an angle as possible. From both these positions the guns must fire en ricochet. But if the ground, or other circumstance, will not admit of either of these being occupied by ricochet batteries, the battery to destroy the fire of a face must be without the prolongation, so as to fire obliquely upon the outside of the face. The last position, in point of advantage, is directly parallel to the face. From these two last positions the guns must fire with the full charges.

The second, or breaching batteries at a siege, are generally placed on the crest of the glacis, within 15 or 18 feet of the covert way; which space serves as the epaulment: but if the foot of the revetment cannot be seen from this situation, they must be placed in the covert way, within 15 feet of the counterscarpe of the ditch. These batteries must be sunk as low as the soles of the embrazures, and are in fact but an enlargement of the sap, run for the lodgement on the glacis or in the covert way. In constructing a battery on the crest of the glacis, attention must be paid that none of the embrazures open upon the traverses of the covert way. These batteries should consist of at least four guns; and if the breadth between the traverses will not admit of this number, at the usual distances, the guns must be closed to 15 or 12 feet from each other.

The mortars are generally at first arranged in battery, adjoining the first gun batteries, or upon the prolongation of the capitals of the works; in which place they are certainly least exposed. Upon the establishment of the half parallels, batteries of howitzers may be formed in their extremities, to enfilade the branches of the covert way; and upon the formation of the third parallel, batteries of howitzers and stone mortars may be formed to enfilade the flanks of the bastions, and annoy the besieged in the covert way. In the lodgement on the glacis, stone and other mortars may also be placed, to drive the besieged from their defences. A great object in the establishment of all these batteries, is to make such an arrangement of them, that they mask the fire of each other as little as possible; and particularly of the first, or ricochet batteries. This may very well be prevented till the establishment on the crest of the glacis, when it becomes in some degree unavoidable: however, even the operations on the glacis may be so arranged, that the ricochet batteries be not masked till the breaching batteries be in a great state of forwardness: a very secure method, and which prevents the soldiers in trenches being alarmed by the shot passing over their heads, is to raise a Parados, or parapet, in the rear of the trenches, at such parts where the fire from the besieger’s batteries crosses them. For further details on this subject, and for the manner of constructing batteries, see the word Battery; also the words Ricochet, Breach, Magazine, Platform, &c.
