A military dictionary

by William Duane

In the firings the loading is quick, the levelling is just, and the officers firm in their commands.

The officers, non-commissioned officers, and men ride well, and the horses are active, vigorous, and well broken.

Movements, in a general sense, may be considered under the following heads, viz.—1st. Offensive movements; the great advantage which attends this movement, consists in the measure having been previously determined upon, and a consequent preparation made for rapid execution before the design is obvious. Much however, will depend, upon the justness of the distances, and of the march in column, having been so taken as to allow of decisive operations. Manœuvre will chiefly operate where an enemy is inferior in number, inexpert in movement, weakly posted, and where the weak point is found out, and is attacked before he can move to strengthen it.

Counter-Movements of defence, are movements calculated to defeat any premeditated attack. According to the regulations they may be briefly explained by observing, that if the flank of one body be thrown forward, that of the other may by similar means be thrown back. If one body prolongs its line to outflank, the other may by the same movement maintain its relative situation. Whatever change of position is made by one body, the other may counteract it by a similar change. If the wing of one body is refused, the wing of the others may be advanced to seize an advantage.

Movements of previous formation, are military dispositions which every general must have carefully digested, before he advances upon a direct line of offensive operations. A body of troops, which has a considerable march to make previous to the attack, must always approach an enemy in one, or more columns, at open or other distances, according to circumstances. Some general knowlege of an enemy’s situation, determines the manner in which he is to be approached, the composition of the columns, the flank of each which leads, and their combination in forming. A nearer view determines a perseverance in the first direction, or a change in the leading flanks, and direction of the columns, in order to form in the most speedy and advantageous manner.

Movements of attack, are made by bodies of men advancing in line or column to attack an opposing enemy. When a considerable body of troops is to act offensively, it must form in line at latest within 1200 or 1500 paces of a posted enemy, unless the ground particularly favor, and cover from the fire of the artillery, the enfilade of which is what chiefly prevents bodies in column from approaching nearer; and that space, under the unceasing fire of their own artillery, troops in line will march over in 18 minutes.

Movements of attack, when they are made from a parallel position, must be either in line, or by a flank of the line in echellon, that flank being reinforced, and the other refused; or from a new and advantageous position taken up, and not provided against by the enemy. From an oblique position the attack is directed against a comparatively weak point of the enemy. Attacks from the centre are more liable to be enfiladed, and are sooner guarded against than from the flank.

Movements of retreat, are combinations of columns of march, covered by positions, and a strong rear guard. Troops are occasionally taken out of the retiring columns of march, to occupy positions and heights; they remain till the rear has passed, and then become the rear guard; this they continue to be, till they find other troops in like manner posted; these last in their turn become also the rear guard, and in this way are the troops of columns in such situations relieved. A rear guard will fall back by the retreat in line—the chequered retreat—the passage of lines—the echellon changes of position.

Movements in echellon of the line. Echellon, or diagonal movements, especially of a great corps, are calculated not only to disconcert an enemy, but likewise to enable the army, which adopts them, either to make a partial attack, or a gradual retreat. The attack may be formed from the centre, or from either of the wings reinforced. If successful, the divisions move up into line to improve the advantage: if repulsed, they are in a good situation to protect the retreat. In advancing, the several bodies move independent, act freely, and are ready to assist: in retiring, they fall gradually back on each other, and thereby give mutual aid and support. Echellon movements, in fact, comprise within themselves all the essential principles of extension and compression, which are found in close or open column, with the additional advantage of being better adapted to throw a considerable line into an oblique position, of presenting a narrow front, with the means of increasing it at pleasure, unexposed to the enemy’s fire and of diminishing it with the same facility and safety.

Echellon Movements on an oblique line, are best calculated to outwing an enemy, or to preserve the points of appui of a wing; possessing this advantage, that such movement may not be perceptible to the enemy, as they are short and independent lines, and when seen at a distance, appear as if a full line.
