Cavalry in Future Wars. Friedrich von Bernhardi
not place the individual out of action immediately, and we may therefore anticipate that many horses will not be stopped in the charge, despite severe injuries. But this drawback the Infantry can meet by opening fire sooner. To the Artillery this does not apply; and, in any case, this objection is not of such importance as to neutralize in any way the other advantages conferred by modern weapons.
Owing to the fact that the extent of the danger zone has been very considerably increased, and that within these zones the amount of fire which has to be faced in a given time has been intensified to a degree which formerly could hardly have been dreamt of, it has ceased to be possible to ride straight at the front of an unshaken enemy.
Thus, essentially the Cavalry has been driven out of its former place of honour on the battle-fields of the plains, and has been compelled to seek the assistance of the cover the ground affords in order to carry its own power of destruction into immediate contact with its enemy, and only under most exceptionally favourable conditions will it still be possible to deliver a charge direct across the open.
Further, as far as the Infantry are concerned, it will be quite the exception to encounter them in closed bodies; generally we shall have to ride against extended lines, which offer a most unfavourable target for our purpose.
The difficulties both of observation and reconnaissance have also been materially increased, for, on the one hand, the increased range of the firearm compels one to keep further away from the enemy, thus making it more difficult to judge with accuracy his strength and positions; on the other, the use of smokeless powder, which no longer reveals the position of the firing line, renders a more thorough searching of the ground even more indispensable than formerly.
The possible participation of the civilian inhabitants of the invaded Nation in the War will hamper most severely all forms of Cavalry action other than on the battle-field. In intersected districts it may, indeed, suffice to paralyze completely the execution of all patrolling duties; and thus the offensive finds itself confronted by a new and permanent element of danger and delay, whose gravity we may estimate by the events which occurred in the latter portion of the Franco-German War, and we may be quite certain that in future all such experiences will be very much intensified.
Lastly, the fall in the numerical proportion of the Cavalry to the other Arms is all to our disadvantage. The greater numbers of the latter cover larger areas, and whether to cover these or to reconnoitre them, it will be necessary to embrace far larger spaces, notwithstanding our relatively smaller numbers—i.e., on each square mile we shall only be able to employ, on an average, a largely reduced number of patrols, etc.
Tactically this want of numbers again affects us. If the necessity to intervene arises, not only have we better firearms against us, but relatively a larger number of troops. Each tactical advantage secured will thus exercise far less effect than formerly upon our opponent, since the fraction of the enemy's force ridden down represents a smaller proportion of his whole Army.
If an Infantry Brigade, one of a force of ten Army Corps, is annihilated, the effect is not nearly so far-reaching as if this Brigade formed part of an Army of two or even three Corps.
If in these changed relations there are obviously factors which materially limit the tactical importance of Cavalry, and which must make the solution of their strategical tasks far more difficult, on the other side we find opportunities in the probable phenomena of a future War which, though less obvious, nevertheless on investigation lead us to the conclusion that the importance of the Arm is even greater than formerly, opening for it a wider sphere of activity, and even on the battle-field revealing new chances of success.
Let us consider these opportunities more closely. The greater the pitch of nervous tension to which men are wrought up in battle, the greater the pitch of excitement reached, the more decisive will be the reaction when the flood-tide of defeat overwhelms them.
Now that all European States are straining every nerve to employ enormous masses of men from the first moment of hostilities, in order thus to gain an advantage whilst their enemy is still concentrating, and when we further consider how these exertions must increase the strain throughout the nation to the very utmost, it must be apparent that the first great decision of Arms must be of overwhelming importance. Not only the troops directly concerned, but the 'masses' behind them, find themselves for the moment involved in the consequences of victory or defeat. Hence the reaction in either direction, owing to the lower average quality of the troops, their greater numbers, the increased difficulties of moving them, and the susceptibility to congestion of their rearward communications, must be far greater and far more disastrous than hitherto under similar tactical conditions.
The more important it is to secure a favourable decision, the more difficult with growing masses to divert an operation once commenced, to give it a new direction or assign it a new objective, the less possible it becomes to alter dispositions which may have been issued on false premises; hence again the greater grows the value of thorough and active reconnoitring.
If this holds good, more especially for the first great collision, it remains also a guiding principle for all future operations; for, on the one side, it is probable that even in its later stages the War will be conducted with comparatively great masses; on the other, as we have seen, the importance of the strategical element has unquestionably grown; hence the value of efficient reconnaissance has been proportionably intensified.
In similar measure the importance of screening has also developed. In proportion as the assailant is compelled to resort to turning movements and surprises, the defender is obliged to have recourse to timely changes of front and unexpected counter-attacks; hence for both timely reconnaissance of the enemy's, as well as for trustworthy screening of one's own operations, the extended employment of the mounted Arms has become imperative. In other words, although reconnaissance and screening for strategical purposes by the Cavalry have been rendered more difficult by the conditions we must expect to meet in the future, on the other hand, they have gained enormously in importance. And it is not in this direction alone that the value of the Arm has increased, but it has also had a new and important field of activity thrown open to it owing to the increased susceptibility the rearward communications of the enemy and his railways have developed.
As a consequence of the increased liability to interruption of these communications, and also of the far more serious confusion to which any such interruption can give rise, it has become far more difficult than in the past to execute offensive flanking operations, changes of front, or counter-attacks, all of which are movements which the practical strategist must bear in mind. On paper and on the map such undertakings appear to present no more elements of friction than formerly, but on the ground itself those who have once seen masses of several corps all huddled together know that things are very different. All such movements nowadays are tied to the railway-lines, and these, again, are congested by the flow of food and ammunition, which must at all costs be maintained. Fresh units also of troops may be coming up to the front, whose arrival is of the last importance in the plans of the generalissimo, and a single broken viaduct may throw confusion into the whole design.
In a densely-populated and fruitful district the resulting failure of supply may be endured, but it is very different when in a poverty-stricken district the supply of a whole Army depends on perhaps a single line of railway.
Thus the Cavalry sees itself confronted by a task in the solution of which it can achieve results of decisive importance in a new direction, for the following reasons: The relative importance of the Arm during actual operations having been materially increased, the period of concentration preceding actual collision (notwithstanding the fact that the actual effectiveness of Cavalry in the face of modern firearms has been decreased) offers opportunities which under certain conditions promise higher results than formerly.
If every delay in the march which may be caused by the action of Cavalry against the flanking lines of advance of an Army concentrating for battle is detrimental, how much greater would be the disorganization resulting from similar operations after defeat! Very rarely in such a case would it be possible to retire eccentrically by the same roads which were used for advance. The beaten troops generally drift back quite involuntarily in the direction into which they have been compelled
