VII.
Skirmishers, by the looseness of their formation, are dangerously exposed to charges from small parties of the enemy’s light cavalry; and in districts destitute of continuous fences, but abounding in hollows, isolated patches of wood, or other features convenient for concealment, such attacks may burst forth with most confusing suddenness. Except in ground absolutely impracticable for cavalry, skirmishers must move in constant expectation of them.
The eye of the officer should be accustomed to recognise habitually those frequently occurring posts of defence against cavalry, copses, walls, hedges, ditches, &c., which are preferable to small squares; and the minds of men should be well prepared by previous instruction and explanation, to recollect, in an instant, in what their strength in such cases consists, and to be undaunted in it.
Against great charges of cavalry, large squares are unquestionably the safest and most efficient; but, in opposition to the small dashes which occur in skirmishing, large squares are often impracticable, and small ones more advisable, as being more rapidly formed and broken up.
Squares have a moral strength in proportion to the mutual acquaintance of the men and officers who compose them. Men of the same company stand better together than those of mixed companies, and men of the same regiment better than those of different corps. However, as in the field thorough mixtures do occur, and as they, if observed, are likely above all other things to bring on charges from the enemy’s cavalry, squares of mixed masses should, in instruction, at times be practised.
It is not necessary to describe the different modes by which, on the drill field, men may be thrown into confusion. When this state of things has been brought about, mixed, irregular, rallying squares can be formed by adding the “double quick” to the ordinary sounds for squares against cavalry.[[13]]
The “double quick” is required to mark the necessity for instantaneous irregular masses, in contradistinction to the more regular squares, which on the drill field skirmishers should always endeavour to form, unless at the time otherwise ordered. It cannot be too constantly upheld as a permanent principle that, even in skirmishing, order is the rule and irregularity the exception.
On the signal “double quick” in immediate succession to the sounds established for the formation of squares,[[14]] officers, exercising most actively their intelligence, in proper numbers and at proper distances, hold up their swords or caps, and the men rush round them into masses of defence without any regard to company or other distinctions.
These mixed squares, as well as all others, may “commence firing”—“cease firing”—“advance”—“retire”—“take ground to a flank,”—or “close” to any particular square, by order, or by the simple sounds for these movements. The “close” may be important to form a large square from several small ones, the cavalry still hovering near.
To these mixed squares also, the word or sound to “extend” may be given. The men then, without regard to regular places, extend away to the right and left from each square, and double into files.
When the ground is nearly occupied, the officer in command fixes on a point of direction, to which the whole conform.
In the event of infantry skirmishers pressing forward to harass a square, or of cavalry endeavouring to prevent its movements by hovering near without charging, one or two ranks from the rear face may, by order, move briskly round by the right and left—double into files—cover the front at a short distance, and rush round again to their places whenever there appears a necessity for the square itself to fire.
In drill in general, and in that of light infantry in particular, instructors confine themselves by far too closely to mere formal directions, to the neglect of pithy practical explanations. In nothing is this last addition more required than in reference to charges of cavalry.
A column of horsemen, coming rapidly on with all its denseness, its height, its dust, its shouts, and its clangour, appears to the untrained mind as altogether irresistible. But appearances are not in themselves realities—let cavalry to the utmost stretch of mortal might,—
“Come as the winds come when forests are rended;”
And “come as the waves come when navies are stranded;”
one thing only will be required to enable squares of infantry, like deep-rooted rocks, to disperse these wild winds and waves, right and left, in dust, froth, and confusion—a well impressed knowledge of their own strength; accompanied as a natural consequence, by a deliberate employment of that, when properly used, most destructive weapon, the musket.[[15]] Nor can more blame attach to cavalry for such results, than would apply to infantry for failing, in clear day-light, before well-barricadoed buildings or well-scarped redoubts. Neither in similar cases owe success, when they get it, to their own conduct or efficiency, but to the needless panic of their enemy.
Such conclusions as to the relative strength of cavalry, are established by a string of facts more or less evident, stretching from Ilium, through Pharsalia, to Waterloo; and every fact is worth a thousand opposing ingenious speculations.
