It is of especial importance that the troops should regain their mobility after an attack has been carried out. When the led horses can be moved, this is an easy matter. Where, however, they are immobile, as will generally be the case where full force has to be put into the fight, there will be considerable loss of time unless it be possible for the led horses to be brought up, part at a time, by any mounted reserve that may have been left in the rear. In spite of this disadvantage, the desire to render the led horses mobile should not be allowed to lead to the undertaking of a dismounted action with insufficient numbers.
This desire to regain the horses as rapidly as possible is frequently to be observed at manœuvres, and not only leads to dismounting and leaving the led horses mobile, but is sometimes allowed to exercise too much influence on the question of where the horses are to be left. In war this consideration should never influence the conduct of the fight, nor lead to the undertaking of a dismounted fight in a half-hearted manner, or precipitately, and thus paralysing the energy of the attack. It should never induce a commander to keep his horses too close to the battlefield and thereby exposed to danger, in order that he may more quickly regain them. If dismounted action has been determined on, the main condition is that the attack should be successfully carried out, and all other matters must be subordinated to this end.
The precepts of the new Regulations do not, to be sure, harmonise with this view. According to them, even when led horses are not required to be mobile, only three-quarters of the men dismount, and each man will hold four horses (366).[25] The number of rifles will be greatly diminished by these measures (by about a quarter); and it is not quite clear, at least to me, what corresponding advantage is to be gained. The measure is, however, so far-reaching that it merits special criticism—the more so as the Regulations themselves lay stress upon the rapid energetic conduct of the fight, and at the same time make such action more difficult by weakening the numbers in the firing-line.
Will the horses thus retain a certain degree of mobility? This would be a mischievous delusion. Even if such measures allow of short distances being covered at a walk on the level drill-ground, such a thing is out of the question in the field and in the proximity of a fight. How will one man lead four horses, and at the same time carry four lances? A practical impossibility.
The Regulations also give no clear directions as to how the lances are to be carried during these evolutions. On the other hand, the number of men formerly detailed fully sufficed for holding the horses when it was not required to move them. There seems therefore to be some other reason for this measure.
I have asked myself the question as to whether the fact that more men are to be left with the horses than formerly will perhaps make it possible to defend the led horses by dismounted patrols. The directions contained in the Regulations (368)[26] that hostile patrols must be kept at a distance by single sentries posted by the commander of the led horses indicates that such was perhaps the intention. But it appears to me that even this object cannot be obtained in such a way. The sentries, if they are to defend the led horses from long-range fire in open country, must be pushed forward in considerable numbers, and very far, almost at rifle range. With single sentries close at hand, no proper protection is afforded, nor can posts be sent out 1,000 yards without giving them a strength which the force cannot afford. If, however, the protection of the led horses in difficult country is to be provided for, a few sentries will most assuredly not suffice to prevent hostile patrols approaching unobserved.
In order to properly protect the led horses they must either be so disposed that they are actually covered from the view and fire of the enemy, or else secured by an escort strong enough to prevent hostile action against them. There is no third course.
Taking these things into consideration I cannot regard the limitation of the number of rifles in the firing-line imposed by the Regulations as justifiable. It seems to me that here a sacrifice is made with no corresponding advantage resulting.
This anxiety seems also to have influenced, to a certain degree, the text of the Regulations. In paragraph 367[27] the attempt is made to compensate in some measure for the danger created by the weakening of the firing-line. That is to say, the squadron leader is allowed in either method of dismounting (with half or three-quarters of the men) to reinforce the firing-line, if the situation demands, by diminishing the number of horse-holders. But it seems to me that this arrangement is not quite practicable, and does not sufficiently take into account the difficulties that will continually result therefrom in the conduct of a real fight.
First of all, it must be regarded as extremely hazardous to leave such measures altogether in the hands of squadron leaders. Only consider, for example, the case of a brigade commander who dismounts half his men in order to keep his led horses mobile, and during the attack makes the discovery that the horses cannot follow because the squadron leaders have reinforced the firing-line from the horse-holders! Throughout the Regulations there are no sort of directions for limiting the initiative of the squadron leader in such matters in the case of the larger bodies of troops.
