There are other reasons, however, why a sharp lookout should be kept during a hostile cavalry charge. All cavalry drill regulations recognize that a charge has greater chances of succeeding when it is made in deep formation, in successive lines, or simultaneously from several directions. The fire of the infantry is distributed, and, unless a good lookout is kept, a part of the cavalry, scarcely or not at all molested by fire, may perhaps succeed in driving the attack home. This will be the case when infantry allows itself to be enticed into developing a heavy fire in a direction from which only a feint is made, while the main attack comes from another, or from several other directions. Well led infantry will, therefore, never employ more rifles in repulsing cavalry than are absolutely necessary, while the mere threat of a cavalry charge will induce badly led infantry to develop an excessive volume of fire. On open terrain, when the approaching cavalry is visible at a considerable distance, and when the infantry itself is exposed to effective fire, the prone aiming position is to be preferred. The men lying flat on the ground are not so easily wounded by the hostile troopers, and the horses will generally avoid stepping on them, besides which, the danger space is greater than when the men fire standing. In rolling or close country, where cavalry cannot be seen by men lying down, the aiming position kneeling or standing should properly be assumed. The losses inflicted by hostile fire must then be endured. Horses and riders are more apt to lose dash when charging an upright human wall that is spouting fire, than when charging a kneeling or prone opponent who scarcely offers an obstacle to the charge. What is of greater importance, however, is that men standing upright can more easily execute a change of front, fire on passing cavalry, and use their bayonets in case the cavalry actually penetrates their line. The British and Italian regulations very properly prescribe that the front rank of a body of infantry in close order should kneel in such cases.
