7. Infantry _breech-loading weapons_ would be very useful to troops in square, when charged by cavalry; since, being rapidly reloaded, they would enable the square to repulse, with a volley, each subdivision successively, where the charging column is formed at the usual distances. But it is doubtful whether, on the whole, these weapons are preferable to muzzle-loaders. Certain it is, that they exhaust the ammunition much more rapidly, and so cause a suspension of fire, and a withdrawal from the line of battle, till a new supply can arrive. And, to obtain this new supply, a long time is generally required; infantry ammunition being usually carried in the second, or more distant ammunition train, instead of the first, or nearest one, as it ought to be. 8. Although a reserved fire is much the most reliable in repulsing cavalry, the men may sometimes be ordered to commence the fire at a _considerable distance_. In such case, they should be instructed to aim at the horses, instead of their riders, as affording a better mark. 9. European cavalry is often practised, on arriving within four hundred yards, or effective grape-shot distance, of an infantry square, to halt, and then open at the centre, unmasking a battery of horse-artillery, which plays for a certain time on the square, when the cavalry closes again, and charges. A square, however, attacked in this manner, is _not in so much danger_ of being broken as might be imagined. The enemy's guns, after being unmasked, would usually require several trial rounds to get the exact range; and our sharpshooters, who could safely be thrown forward one hundred yards, with the new rifled arms, ought, in the mean time, to inflict such loss on the cavalry, as well as on the battery, as to cause it either to retire, or to charge feebly, and, therefore, ineffectively. At the very worst, the square would have ample time to re-form its ranks, and deliver a deadly volley before the cavalry could reach it, as it also would if this operation were attempted much nearer, say at two hundred yards. In this last case, a few volleys from the square itself, with the new arms, would probably be destructive enough to prevent the charge altogether. 10. It is hardly necessary to observe, that troops formed in square, when charged by cavalry, can secure their safety only by _standing firm_. A single opening will suffice to let in the enemy, who will then easily ride over the square, and cut it in pieces. Whereas, if the square remain unbroken, cavalry can inflict upon it no loss, or but a trifling one. 11. In repulsing a cavalry charge, coolness and presence of mind will sometimes enable troops to accomplish _extraordinary results_.
