respectively. At this day both classes alike carry both a steel weapon and a firearm. A vast amount may depend (and otherwise I should not be writing) on the way the weapon may be permitted to govern mounted tactics, but from time immemorial it has been the superior mobility derived from the horse that has given to Cavalry, using the word in its widest sense, all the special functions which distinguish it from Infantry. Let us beware, then, if we find a writer coupling together the horse and the steel weapon as though, by some immutable law, they were inseparable factors of efficiency. Surely, they are not. The common denominator is the horse. To ignore the lance or sword is not, with all respect to Sir John French, to ignore the horse.[11] The sole issue is, by the agency of what weapon can the horse, in conjunction with the will and the manual skill and strength of the man, be used to the best advantage?
If the horse has his merits, he has his drawbacks. Let us consider both, strictly in relation to the question of weapons. Let us remember at the outset what is too often forgotten, that the weapon is only used in actual combats. In all those phases of war which precede combat, for the rapid transportation from one point to another of any body of troops great or small, ease of movement and secrecy of movement are the paramount considerations. In a strategic raid or a tactical turning movement, in any operation, offensive or defensive, from the action of a patrol to the action of a division, the carriage of troops into the zone of combat is a problem of mobility and secrecy pure and simple. Any weapon which unduly burdens the horse or rider, or renders them unduly conspicuous, is an obstacle to those ends only to be justified by showing that it is indispensable for combats. Similarly, any system of training which is designed to facilitate combat with any particular weapon, but which reacts unfavourably upon mobility or secrecy prior to the phase of combat, is, to that extent, to be deprecated. The scout exemplifies the principle in its extreme form. Acting as a scout, he is not meant to fight, but to move quickly, and to see without being seen. It is quite possible that a few unarmed scouts might decide the fate of armies; certainly scouts have, in fact, done so without recourse to weapons.
Hitherto, so far as the merits and drawbacks of the horse are involved, we are concerned only with his speed and endurance on the one hand, and his visibility on the other. But as soon as we regard the horse as entering the zone of combat, we are confronted with a new and serious qualification to his value—namely, his vulnerability. This, in one degree or another, is an invariable source of weakness. The danger to be incurred may be reduced to a minimum, as in the case of the pursuit of utterly demoralized troops. Surprise and stratagem may modify the risk to an indefinite extent, but the risk always exists, and can be overcome in the last resort only by a mobility so high as to transcend it. We arrive thus at the two opposing factors, mobility and vulnerability, the one tending to counteract the other; and from the physical point of view it is upon the correct estimate of the relative strength of these two factors that the solution of every tactical mounted problem depends. It goes without saying that the invention and improvement of the firearm, by immensely extending the zone of vulnerability and immensely increasing the degree of vulnerability within that zone, has profoundly affected the conditions of this ever-present problem. The reader, no doubt, will add that the same general principle applies to Infantry. True; but there is especially good reason to insist on its application to mounted troops.
Arrived at this point, we must, for the sake of clearness, disregard the hybrid type of horseman, and picture, for the time being, as separate personalities, the horseman armed with a steel weapon and the horseman armed with a firearm. Later on we will fuse the two personalities in one, when we come to consider training. But for the present I want to concentrate attention on the relative value in combat of fire and steel.
Let us take first the horseman armed with the steel weapon.
Two characteristics must be noted at once: (1) His steel weapon is used from horseback only; (2) as against riflemen, whether mounted or dismounted, it is only used in offence. In both these respects it differs from the bayonet.
In encounters on horseback with other steel horsemen (assumed, as before, to be pure steel horsemen) it may in a sense be said to be used both in defence and offence, but these encounters do not immediately concern us. If two bodies of horse agree to settle accounts in that way, that is their own affair. The best swordsmen and riders will win. We are contrasting fire and steel, and the steel as against riflemen is only used in offence—why will soon appear. We must picture, then, our steel horseman as acting offensively.
Now, in the physical sphere, while the improvements in the firearm have greatly increased both the zone and degree of the horseman’s vulnerability, there is nothing to redress the balance in favour of the horse or the steel weapon. Both the speed of the former and the efficacy of the latter remain practically constant quantities from age to age. By comparison with firearms, steel weapons may be said to be incapable of improvement. As missiles they have been obsolete for centuries. As manual implements their range is the range of a man’s arm, plus their own length. They cannot be used at any point short of actual contact with the enemy, a point which must be reached with the rider in the saddle, while the growth in the destructive efficacy of the firearm, directed against so large a target as that presented by rider and animal combined, has steadily reduced the horseman’s power of reaching that point without mishap. Even after he reaches it, he still presents the same large area of vulnerable surface as compared with a man on foot.
On the other hand, if and when he obtains contact, he gains in two ways. His weapon gains in efficacy relatively to the firearm, since for the moment the factor of range has been equalized, or almost equalized. Secondly, his horse has a new merit, its weight; but this is not an individual, but a collective merit, only developed by the combined weight of many horses.
That brings me to a consideration of the steel weapon’s sole function in war—the shock charge. We are to regard the man now as a member of a mass. He and his comrades, by the impact due to the united momentum of their horses, aim at producing “shock,” with its stunning physical effect on the defence. Aided by shock, they use their steel weapons.
Now, what are the necessary conditions for the production of genuine shock? First, the horsemen must attack in dense formation, precisely the formation which offers the best target for rifle-fire. Second, in order to make shock effective, the riflemen who are the object of attack must also be in tolerably dense formation, otherwise there is nothing substantial on which to exert shock. This, of course, is one of the greatest of the modern limitations to shock, for the whole tendency in war is towards loose and away from dense formations, the cause being the increased efficacy of firearms.
Thirdly, since the ground must be covered at high speed and with absolute cohesion in order to obtain momentum and to minimize vulnerability, the ground must in every case be such as to permit of high speed, fairly smooth, fairly level, fairly open, and, above all, continuously practicable up to the supreme moment of contact. Any concealed obstruction or entanglement met with in traversing the danger zone may irretrievably compromise the charge. For true shock a ragged, disjointed impact is useless. Clean, sharp, and shattering impact is the only end worth attainment. The ground may fulfil all these requirements up to the last few yards, but in the last few yards a sunk ditch, a wire fence, not to speak of more visible obstacles, such as hedges, walls, earthworks, or any of the common features of an ordinary defensive position, may render the whole enterprise nugatory. If the reader will bear in mind the average character of ground in European countries, he will recognize another serious limitation to the employment of shock.
Fourthly, supposing that all the conditions hitherto enumerated are satisfied, speed is still dependent on the freshness of the horses. Whatever their exertions in the performance of the innumerable and highly responsible duties of Cavalry not necessarily involving combat, the horses must be capable, whenever and wherever the opportunity occurs, of a vigorous gallop, ending with the super-gallop known as the “charge,” at this supreme moment—the one and only moment in which the steel horseman fulfils his rôle. Modern war proves this standard of freshness to be chimerical. In peace-training you may compromise on speed as much as you please, and in point of fact the rigorous directions of “Cavalry Training” (p. 125) are often diluted to a canter ending in a short gallop. Futile compromise! The less speed, the greater and longer the vulnerability of the mass, and the less shock.
