11. Cavalry must never pursue, unless its supports are close at hand.
In pursuing, it must be circumspect, and not go too far. Union and order are indispensable; for, without them, a slight resistance may suffice to cause a repulse.
VIII.—Its Attack on Infantry.
First, as to its [Attack Generally.]
Secondly, its attack [On Squares.]
1. Cavalry must avoid distant engagements with infantry; in which the latter must always have the advantage.
2. The slightest cavalry charge on the flank of infantry will rout it.
3. As to a cavalry attack in front: If the infantry stand firm, the chances are against its success. If the infantry cannot be attacked in flank, the cavalry should therefore wait till it has been shattered by artillery, or has become exhausted, or demoralized, or till it begins to manœuvre.
4. If the infantry be in line, or in column, cavalry should attack it in flank; if in square, at one of its angles; if in several squares, at one of its flank ones, so as to avoid a cross-fire from the other squares. If a flank square be broken, the next one to it, being no longer protected by the fire of any other square, may be attacked with the same prospect of success; and so on successively.
5. But if the hostile infantry have supporting cavalry, we must not charge in such a manner as to enable it to take us in flank.
