To March before any central point or the left flank. The battalion makes a successive countermarch from the right flank towards the left, and when the right division is arrived at the point from whence it is to advance in column, it again countermarches to its right, a space equal to its front, then faces, moves on, and is thus successively followed by part of the battalion. The other part of the battalion, beyond the point of advancing, faces inwards, when necessary makes a progressive march in file, and then fronts. Each division belonging to this part of the battalion follows successively till the whole stand in column.
To March by files behind the centre or left flank. The right proportion of the battalion countermarches from the right by files successively by the rear, and the other proportion of the battalion, according to circumstances, makes a progressive march by files from its right to the central point, and there begins to countermarch; at that point the leading or head division fronts into column, and moves on, each successive division doing the same. When the left of a battalion is to be in front, the same operations take place by an inverse march of the several divisions.
This method, however, of marching by files into open column, should be resorted to as little as possible, and never when it can be conveniently avoided. The formation of open column from battalion and line is better done by the wheelings of companies, subdivisions, or sections.
To March up in charging order, is to advance towards the enemy’s line with a quick but firm and steady pace, till you get within a few paces of the opposing body, when an increased rapidity must be given to the whole, but not to run so as to lose breath, the officers on this occasion must be particularly attentive to the several divisions in their charge, keeping them well dressed to their centre, and thereby preventing dangerous openings and consequent confusion. The French call this the [pas de Charge].—Which see under [Pas]. See Am. Mil. Lib.
Points of March, one or more objects which ought always to be prepared for the direction of any considerable body, every leader of which who moves directly forward in front, must take care to conduct it in a line perpendicular to that front. But should a leader, either in file or front, have only one marked point of march, ascertained to him, he will himself instantly look out for small intermediate points.
To March in file to a flank, is to reduce a line by marching out from its several divisions towards a given flank, there to remain in close or open column, of brigades, regiments, grand divisions, companies, &c. Nothing is more essential in all deployments into line, and in the internal movements of the divisions of the battalion, than the accuracy of the march in file. After facing, and at the word march, the whole are directed to step off at the same instant, each man replacing, or rather overstepping the foot of his preceding comrade: that is the right foot of the second man comes within the left foot of the first, and thus of every one, more or less overlapping, according to the closeness, or openness of the files and the length of step. The front rank will march straight along the given line, each soldier of that rank must look along the necks of those before him, and never to right or left. The centre and rear ranks must look to, and regulate themselves by their leaders of the front rank, and always dress in their file. File marching is always made in quick time.
March of a battalion in line, is a regular continuity of files advancing forward in two or three ranks, each rear file preserving a perpendicular direction to its leader, and the ranks being kept parallel to each other at given distances; so that the whole line shall continue straight without being deformed by a concavity or convexity of figure. The march of the battalion in line, either to front or rear, being the most important and most difficult of all movements, every exertion of the commanding officer, and every attention of officers and men, become peculiarly necessary to attain this end. The great and indispensible requisites of this operation are, that the direction of the march be perpendicular to the front of the battalion as then standing; that the shoulders and body of each individual be perfectly square, that the files touch lightly at the elbow only, and finally, that an accurate equality of cadence and length of step be given by the advanced guides or serjeants, whom the battalion in every respect must cover, and which equality of cadence and length of step every individual must follow and comply with. If these essential rules are not observed, its direction will be lost, the different parts will open and attempt to close, and by so doing, a floating of the whole will ensue, and disorder will arise at a time when the remedy is so difficult, and perfect order so imperiously wanted.
In order to ensure these essential requisites, and to produce perfect correctness, the serjeants must be trained to this peculiar object, on whose exactness of cadence, regularity of step, squareness of body, and precision of movement, the greatest dependance can be placed, these are the proper guides of manoeuvre. The habitual post of the two principal directing serjeants, is to be in the centre of the battalion, betwixt the colors. One of them is posted in the front rank, and one in the rear, that they thereby may be ready to move out when the battalion is to march; another also covers them in the supernumerary rank.
Whenever the battalion is formed in line and halted, the front directing serjeant or guide, after having placed himself perfectly and squarely in the rank, must instantly cast his eyes down the centre of his body, from the junction of his two heels, and by repeated trials endeavor to, take up and prolong a line perpendicular to himself, and to the battalion; for this purpose he is by no means to begin with looking out for a distant object, but if such by chance should present itself in the prolongation of the line, extending from his own person, he may remark it. He is therefore rather to observe and take up any accidental small point on the ground within 100 or 150 paces. Intermediate ones cannot be wanting, nor the renewal of such as he afterwards successively approaches to in his march. In this manner he is prepared, subject to the future correction of the commanding officer, to conduct the march.
To March forward or advance in line, when the battalion has been halted and correctly dressed—Is to step off, according to any given word of command, in quick or ordinary time, and to march over a perpendicular line of direction, without deviating to the right or left, or unnecessarily opening or closing during the movement; the commanding officer having previously placed himself 10 or 12 paces behind the exact line of the directing serjeant, will, if such file could be depended on, as standing truly perpendicular to the battalion, (and great care must be taken to place it so) remark the line of its prolongation, and thereby ascertain the direction in which it should march; but, as such precision cannot be relied on, he will from his own eye and from having the square of the battalion before him, with promptitude make such correction, and observe such object to the right or left, as may appear to him the true one; and in doing this, he will not at once look out for a distant object, but will hit on it, by prolonging the line from the person of the directing serjeant to the front; or he will order the covering serjeant to run out 20 paces, and will place him in the line in which he thinks the battalion ought to advance. The directing serjeant then takes his direction along the line which passes from himself, betwixt the heels of the advanced serjeant, and preserves such line in advancing, by constantly keeping his object in view.
