CHAPTER IV. THE COMBAT IN GENERAL (CONTINUATION)
IN the last chapter we showed the destruction of the enemy as the true object of the combat, and we have sought to prove by a special consideration of the point, that this is true in the majority of cases, and in respect to the most important battles, because the destruction of the enemy's Army is always the preponderating object in War. The other objects which may be mixed up with this destruction of the enemy's force, and may have more or less influence, we shall describe generally in the next chapter, and become better acquainted with by degrees afterwards; here we divest the combat of them entirely, and look upon the destruction of the enemy as the complete and sufficient object of any combat.
What are we now to understand by destruction of the enemy's Army? A diminution of it relatively greater than that on our own side. If we have a great superiority in numbers over the enemy, then naturally the same absolute amount of loss on both sides is for us a smaller one than for him, and consequently may be regarded in itself as an advantage. As we are here considering the combat as divested of all (other) objects, we must also exclude from our consideration the case in which the combat is used only indirectly for a greater destruction of the enemy's force; consequently also, only that direct gain which has been made in the mutual process of destruction, is to be regarded as the object, for this is an absolute gain, which runs through the whole campaign, and at the end of it will always appear as pure profit. But every other kind of victory over our opponent will either have its motive in other objects, which we have completely excluded here, or it will only yield a temporary relative advantage. An example will make this plain.
If by a skilful disposition we have reduced our opponent to such a dilemma, that he cannot continue the combat without danger, and after some resistance he retires, then we may say, that we have conquered him at that point; but if in this victory we have expended just as many forces as the enemy, then in closing the account of the campaign, there is no gain remaining from this victory, if such a result can be called a victory. Therefore the overcoming the enemy, that is, placing him in such a position that he must give up the fight, counts for nothing in itself, and for that reason cannot come under the definition of object. There remains, therefore, as we have said, nothing over except the direct gain which we have made in the process of destruction; but to this belong not only the losses which have taken place in the course of the combat, but also those which, after the withdrawal of the conquered part, take place as direct consequences of the same.
Now it is known by experience, that the losses in physical forces in the course of a battle seldom present a great difference between victor and vanquished respectively, often none at all, sometimes even one bearing an inverse relation to the result, and that the most decisive losses on the side of the vanquished only commence with the retreat, that is, those which the conqueror does not share with him. The weak remains of battalions already in disorder are cut down by cavalry, exhausted men strew the ground, disabled guns and broken caissons are abandoned, others in the bad state of the roads cannot be removed quickly enough, and are captured by the enemy's troops, during the night numbers lose their way, and fall defenceless into the enemy's hands, and thus the victory mostly gains bodily substance after it is already decided. Here would be a paradox, if it did not solve itself in the following manner.
The loss in physical force is not the only one which the two sides suffer in the course of the combat; the moral forces also are shaken, broken, and go to ruin. It is not only the loss in men, horses and guns, but in order, courage, confidence, cohesion and plan, which come into consideration when it is a question whether the fight can be still continued or not. It is princ.i.p.ally the moral forces which decide here, and in all cases in which the conqueror has lost as heavily as the conquered, it is these alone.
The comparative relation of the physical losses is difficult to estimate in a battle, but not so the relation of the moral ones. Two things princ.i.p.ally make it known. The one is the loss of the ground on which the fight has taken place, the other the superiority of the enemy's. The more our reserves have diminished as compared with those of the enemy, the more force we have used to maintain the equilibrium; in this at once, an evident proof of the moral superiority of the enemy is given which seldom fails to stir up in the soul of the Commander a certain bitterness of feeling, and a sort of contempt for his own troops. But the princ.i.p.al thing is, that men who have been engaged for a long continuance of time are more or less like burnt-out cinders; their ammunition is consumed; they have melted away to a certain extent; physical and moral energies are exhausted, perhaps their courage is broken as well. Such a force, irrespective of the diminution in its number, if viewed as an organic whole, is very different from what it was before the combat; and thus it is that the loss of moral force may be measured by the reserves that have been used as if it were on a foot-rule.
Lost ground and want of fresh reserves, are, therefore, usually the princ.i.p.al causes which determine a retreat; but at the same time we by no means exclude or desire to throw in the shade other reasons, which may lie in the interdependence of parts of the Army, in the general plan, &c.
Every combat is therefore the b.l.o.o.d.y and destructive measuring of the strength of forces, physical and moral; whoever at the close has the greatest amount of both left is the conqueror.
In the combat the loss of moral force is the chief cause of the decision; after that is given, this loss continues to increase until it reaches its culminating-point at the close of the whole act. This then is the opportunity the victor should seize to reap his harvest by the utmost possible restrictions of his enemy's forces, the real object of engaging in the combat. On the beaten side, the loss of all order and control often makes the prolongation of resistance by individual units, by the further punishment they are certain to suffer, more injurious than useful to the whole. The spirit of the ma.s.s is broken; the original excitement about losing or winning, through which danger was forgotten, is spent, and to the majority danger now appears no longer an appeal to their courage, but rather the endurance of a cruel punishment. Thus the instrument in the first moment of the enemy's victory is weakened and blunted, and therefore no longer fit to repay danger by danger.
This period, however, pa.s.ses; the moral forces of the conquered will recover by degrees, order will be restored, courage will revive, and in the majority of cases there remains only a small part of the superiority obtained, often none at all. In some cases, even, although rarely, the spirit of revenge and intensified hostility may bring about an opposite result. On the other hand, whatever is gained in killed, wounded, prisoners, and guns captured can never disappear from the account.
The losses in a battle consist more in killed and wounded; those after the battle, more in artillery taken and prisoners. The first the conqueror shares with the conquered, more or less, but the second not; and for that reason they usually only take place on one side of the conflict, at least, they are considerably in excess on one side.
Artillery and prisoners are therefore at all times regarded as the true trophies of victory, as well as its measure, because through these things its extent is declared beyond a doubt. Even the degree of moral superiority may be better judged of by them than by any other relation, especially if the number of killed and wounded is compared therewith; and here arises a new power increasing the moral effects.
We have said that the moral forces, beaten to the ground in the battle and in the immediately succeeding movements, recover themselves gradually, and often bear no traces of injury; this is the case with small divisions of the whole, less frequently with large divisions; it may, however, also be the case with the main Army, but seldom or never in the State or Government to which the Army belongs. These estimate the situation more impartially, and from a more elevated point of view, and recognise in the number of trophies taken by the enemy, and their relation to the number of killed and wounded, only too easily and well, the measure of their own weakness and inefficiency.
In point of fact, the lost balance of moral power must not be treated lightly because it has no absolute value, and because it does not of necessity appear in all cases in the amount of the results at the final close; it may become of such excessive weight as to bring down everything with an irresistible force. On that account it may often become a great aim of the operations of which we shall speak elsewhere. Here we have still to examine some of its fundamental relations.
The moral effect of a victory increases, not merely in proportion to the extent of the forces engaged, but in a progressive ratio-that is to say, not only in extent, but also in its intensity. In a beaten detachment order is easily restored. As a single frozen limb is easily revived by the rest of the body, so the courage of a defeated detachment is easily raised again by the courage of the rest of the Army as soon as it rejoins it. If, therefore, the effects of a small victory are not completely done away with, still they are partly lost to the enemy. This is not the case if the Army itself sustains a great defeat; then one with the other fall together. A great fire attains quite a different heat from several small ones.
Another relation which determines the moral value of a victory is the numerical relation of the forces which have been in conflict with each other. To beat many with few is not only a double success, but shows also a greater, especially a more general superiority, which the conquered must always be fearful of encountering again. At the same time this influence is in reality hardly observable in such a case. In the moment of real action, the notions of the actual strength of the enemy are generally so uncertain, the estimate of our own commonly so incorrect, that the party superior in numbers either does not admit the disproportion, or is very far from admitting the full truth, owing to which, he evades almost entirely the moral disadvantages which would spring from it. It is only hereafter in history that the truth, long suppressed through ignorance, vanity, or a wise discretion, makes its appearance, and then it certainly casts a l.u.s.tre on the Army and its Leader, but it can then do nothing more by its moral influence for events long past.
If prisoners and captured guns are those things by which the victory princ.i.p.ally gains substance, its true crystallisations, then the plan of the battle should have those things specially in view; the destruction of the enemy by death and wounds appears here merely as a means to an end.
How far this may influence the dispositions in the battle is not an affair of Strategy, but the decision to fight the battle is in intimate connection with it, as is shown by the direction given to our forces, and their general grouping, whether we threaten the enemy's flank or rear, or he threatens ours. On this point, the number of prisoners and captured guns depends very much, and it is a point which, in many cases, tactics alone cannot satisfy, particularly if the strategic relations are too much in opposition to it.
The risk of having to fight on two sides, and the still more dangerous position of having no line of retreat left open, paralyse the movements and the power of resistance; further, in case of defeat, they increase the loss, often raising it to its extreme point, that is, to destruction. Therefore, the rear being endangered makes defeat more probable, and, at the same time, more decisive.
From this arises, in the whole conduct of the War, especially in great and small combats, a perfect instinct to secure our own line of retreat and to seize that of the enemy; this follows from the conception of victory, which, as we have seen, is something beyond mere slaughter.
In this effort we see, therefore, the first immediate purpose in the combat, and one which is quite universal. No combat is imaginable in which this effort, either in its double or single form, does not go hand in hand with the plain and simple stroke of force. Even the smallest troop will not throw itself upon its enemy without thinking of its line of retreat, and, in most cases, it will have an eye upon that of the enemy also.
We should have to digress to show how often this instinct is prevented from going the direct road, how often it must yield to the difficulties arising from more important considerations: we shall, therefore, rest contented with affirming it to be a general natural law of the combat.
It is, therefore, active; presses everywhere with its natural weight, and so becomes the pivot on which almost all tactical and strategic manoeuvres turn.
If we now take a look at the conception of victory as a whole, we find in it three elements:- 1. The greater loss of the enemy in physical power.
2. In moral power.
3. His open avowal of this by the relinquishment of his intentions.
The returns made up on each side of losses in killed and wounded, are never exact, seldom truthful, and in most cases, full of intentional misrepresentations. Even the statement of the number of trophies is seldom to be quite depended on; consequently, when it is not considerable it may also cast a doubt even on the reality of the victory. Of the loss in moral forces there is no reliable measure, except in the trophies: therefore, in many cases, the giving up the contest is the only real evidence of the victory. It is, therefore, to be regarded as a confession of inferiority-as the lowering of the flag, by which, in this particular instance, right and superiority are conceded to the enemy, and this degree of humiliation and disgrace, which, however, must be distinguished from all the other moral consequences of the loss of equilibrium, is an essential part of the victory. It is this part alone which acts upon the public opinion outside the Army, upon the people and the Government in both belligerent States, and upon all others in any way concerned.
But renouncement of the general object is not quite identical with quitting the field of battle, even when the battle has been very obstinate and long kept up; no one says of advanced posts, when they retire after an obstinate combat, that they have given up their object; even in combats aimed at the destruction of the enemy's Army, the retreat from the battlefield is not always to be regarded as a relinquishment of this aim, as for instance, in retreats planned beforehand, in which the ground is disputed foot by foot; all this belongs to that part of our subject where we shall speak of the separate object of the combat; here we only wish to draw attention to the fact that in most cases the giving up of the object is very difficult to distinguish from the retirement from the battlefield, and that the impression produced by the latter, both in and out of the Army, is not to be treated lightly.
For Generals and Armies whose reputation is not made, this is in itself one of the difficulties in many operations, justified by circ.u.mstances when a succession of combats, each ending in retreat, may appear as a succession of defeats, without being so in reality, and when that appearance may exercise a very depressing influence. It is impossible for the retreating General by making known his real intentions to prevent the moral effect spreading to the public and his troops, for to do that with effect he must disclose his plans completely, which of course would run counter to his princ.i.p.al interests to too great a degree.
In order to draw attention to the special importance of this conception of victory we shall only refer to the battle of Soor,(*) the trophies from which were not important (a few thousand prisoners and twenty guns), and where Frederick proclaimed his victory by remaining for five days after on the field of battle, although his retreat into Silesia had been previously determined on, and was a measure natural to his whole situation. According to his own account, he thought he would hasten a peace by the moral effect of his victory. Now although a couple of other successes were likewise required, namely, the battle at Katholisch Hennersdorf, in Lusatia, and the battle of Kesseldorf, before this peace took place, still we cannot say that the moral effect of the battle of Soor was nil.
(*) Soor, or Sohr, Sept. 30, 1745; Hennersdorf, Nov. 23, 1745; Kealteldorf, Dec. 15, 1745, all in the Second Silesian War.
If it is chiefly the moral force which is shaken by defeat, and if the number of trophies reaped by the enemy mounts up to an unusual height, then the lost combat becomes a rout, but this is not the necessary consequence of every victory. A rout only sets in when the moral force of the defeated is very severely shaken then there often ensues a complete incapability of further resistance, and the whole action consists of giving way, that is of flight.
Jena and Belle Alliance were routs, but not so Borodino.
Although without pedantry we can here give no single line of separation, because the difference between the things is one of degrees, yet still the retention of the conception is essential as a central point to give clearness to our theoretical ideas and it is a want in our terminology that for a victory over the enemy tantamount to a rout, and a conquest of the enemy only tantamount to a simple victory, there is only one and the same word to use.
CHAPTER V. ON THE SIGNIFICATION OF THE COMBAT
HAVING in the preceding chapter examined the combat in its absolute form, as the miniature picture of the whole War, we now turn to the relations which it bears to the other parts of the great whole. First we inquire what is more precisely the signification of a combat.
As War is nothing else but a mutual process of destruction, then the most natural answer in conception, and perhaps also in reality, appears to be that all the powers of each party unite in one great volume and all results in one great shock of these ma.s.ses. There is certainly much truth in this idea, and it seems to be very advisable that we should adhere to it and should on that account look upon small combats at first only as necessary loss, like the shavings from a carpenter's plane. Still, however, the thing cannot be settled so easily.
That a multiplication of combats should arise from a fractioning of forces is a matter of course, and the more immediate objects of separate combats will therefore come before us in the subject of a fractioning of forces; but these objects, and together with them, the whole ma.s.s of combats may in a general way be brought under certain cla.s.ses, and the knowledge of these cla.s.ses will contribute to make our observations more intelligible.
Destruction of the enemy's military forces is in reality the object of all combats; but other objects may be joined thereto, and these other objects may be at the same time predominant; we must therefore draw a distinction between those in which the destruction of the enemy's forces is the princ.i.p.al object, and those in which it is more the means. The destruction of the enemy's force, the possession of a place or the possession of some object may be the general motive for a combat, and it may be either one of these alone or several together, in which case however usually one is the princ.i.p.al motive. Now the two princ.i.p.al forms of War, the offensive and defensive, of which we shall shortly speak, do not modify the first of these motives, but they certainly do modify the other two, and therefore if we arrange them in a scheme they would appear thus:-
OFFENSIVE. DEFENSIVE.
1. Destruction of enemy's force 1. Destruction of enemy's force.
2. Conquest of a place. 2. Defence of a place.
3. Conquest of some object. 3. Defence of some object.
These motives, however, do not seem to embrace completely the whole of the subject, if we recollect that there are reconnaissances and demonstrations, in which plainly none of these three points is the object of the combat. In reality we must, therefore, on this account be allowed a fourth cla.s.s. Strictly speaking, in reconnaissances in which we wish the enemy to show himself, in alarms by which we wish to wear him out, in demonstrations by which we wish to prevent his leaving some point or to draw him off to another, the objects are all such as can only be attained indirectly and UNDER THE PRETEXT OF ONE OF THE THREE OBJECTS SPECIFIED IN THE TABLE, usually of the second; for the enemy whose aim is to reconnoitre must draw up his force as if he really intended to attack and defeat us, or drive us off, &c. &c. But this pretended object is not the real one, and our present question is only as to the latter; therefore, we must to the above three objects of the offensive further add a fourth, which is to lead the enemy to make a false conclusion. That offensive means are conceivable in connection with this object, lies in the nature of the thing.
On the other hand we must observe that the defence of a place may be of two kinds, either absolute, if as a general question the point is not to be given up, or relative if it is only required for a certain time. The latter happens perpetually in the combats of advanced posts and rear guards.
That the nature of these different intentions of a combat must have an essential influence on the dispositions which are its preliminaries, is a thing clear in itself. We act differently if our object is merely to drive an enemy's post out of its place from what we should if our object was to beat him completely; differently, if we mean to defend a place to the last extremity from what we should do if our design is only to detain the enemy for a certain time. In the first case we trouble ourselves little about the line of retreat, in the latter it is the princ.i.p.al point, &c.
But these reflections belong properly to tactics, and are only introduced here by way of example for the sake of greater clearness. What Strategy has to say on the different objects of the combat will appear in the chapters which touch upon these objects. Here we have only a few general observations to make, first, that the importance of the object decreases nearly in the order as they stand above, therefore, that the first of these objects must always predominate in the great battle; lastly, that the two last in a defensive battle are in reality such as yield no fruit, they are, that is to say, purely negative, and can, therefore, only be serviceable, indirectly, by facilitating something else which is positive. IT IS, THEREFORE, A BAD SIGN OF THE STRATEGIC SITUATION IF BATTLES OF THIS KIND BECOME TOO FREQUENT.
CHAPTER VI. DURATION OF THE COMBAT
IF we consider the combat no longer in itself but in relation to the other forces of War, then its duration acquires a special importance.
This duration is to be regarded to a certain extent as a second subordinate success. For the conqueror the combat can never be finished too quickly, for the vanquished it can never last too long. A speedy victory indicates a higher power of victory, a tardy decision is, on the side of the defeated, some compensation for the loss.
This is in general true, but it acquires a practical importance in its application to those combats, the object of which is a relative defence.
Here the whole success often lies in the mere duration. This is the reason why we have included it amongst the strategic elements.
The duration of a combat is necessarily bound up with its essential relations. These relations are, absolute magnitude of force, relation of force and of the different arms mutually, and nature of the country. Twenty thousand men do not wear themselves out upon one another as quickly as two thousand: we cannot resist an enemy double or three times our strength as long as one of the same strength; a cavalry combat is decided sooner than an infantry combat; and a combat between infantry only, quicker than if there is artillery(*) as well; in hills and forests we cannot advance as quickly as on a level country; all this is clear enough.
(*) The increase in the relative range of artillery and the introduction of shrapnel has altogether modified this conclusion.
From this it follows, therefore, that strength, relation of the three arms, and position, must be considered if the combat is to fulfil an object by its duration; but to set up this rule was of less importance to us in our present considerations than to connect with it at once the chief results which experience gives us on the subject.
Even the resistance of an ordinary Division of 8000 to 10,000 men of all arms even opposed to an enemy considerably superior in numbers, will last several hours, if the advantages of country are not too preponderating, and if the enemy is only a little, or not at all, superior in numbers, the combat will last half a day. A Corps of three or four Divisions will prolong it to double the time; an Army of 80,000 or 100,000 to three or four times. Therefore the ma.s.ses may be left to themselves for that length of time, and no separate combat takes place if within that time other forces can be brought up, whose co-operation mingles then at once into one stream with the results of the combat which has taken place.
These calculations are the result of experience; but it is important to us at the same time to characterise more particularly the moment of the decision, and consequently the termination.
CHAPTER VII. DECISION OF THE COMBAT
No battle is decided in a single moment, although in every battle there arise moments of crisis, on which the result depends. The loss of a battle is, therefore, a gradual falling of the scale. But there is in every combat a point of time (*) (*) Under the then existing conditions of armament understood. This point is of supreme importance, as practically the whole conduct of a great battle depends on a correct solution of this question-viz., How long can a given command prolong its resistance? If this is incorrectly answered in practice-the whole manoeuvre depending on it may collapse-e.g., Kouroupatkin at Liao-Yang, September 1904.
when it may be regarded as decided, in such a way that the renewal of the fight would be a new battle, not a continuation of the old one. To have a clear notion on this point of time, is very important, in order to be able to decide whether, with the prompt a.s.sistance of reinforcements, the combat can again be resumed with advantage.
Often in combats which are beyond restoration new forces are sacrificed in vain; often through neglect the decision has not been seized when it might easily have been secured. Here are two examples, which could not be more to the point: When the Prince of Hohenlohe, in 1806, at Jena,(*) with 35,000 men opposed to from 60,000 to 70,000, under Buonaparte, had accepted battle, and lost it-but lost it in such a way that the 35,000 might be regarded as dissolved-General Ruchel undertook to renew the fight with about 12,000; the consequence was that in a moment his force was scattered in like manner.
(*) October 14, 1806.
On the other hand, on the same day at Auerstadt, the Prussians maintained a combat with 25,000, against Davoust, who had 28,000, until mid-day, without success, it is true, but still without the force being reduced to a state of dissolution without even greater loss than the enemy, who was very deficient in cavalry;-but they neglected to use the reserve of 18,000, under General Kalkreuth, to restore the battle which, under these circ.u.mstances, it would have been impossible to lose.
Each combat is a whole in which the partial combats combine themselves into one total result. In this total result lies the decision of the combat. This success need not be exactly a victory such as we have denoted in the sixth chapter, for often the preparations for that have not been made, often there is no opportunity if the enemy gives way too soon, and in most cases the decision, even when the resistance has been obstinate, takes place before such a degree of success is attained as would completely satisfy the idea of a victory.
We therefore ask, Which is commonly the moment of the decision, that is to say, that moment when a fresh, effective, of course not disproportionate, force, can no longer turn a disadvantageous battle?
If we pa.s.s over false attacks, which in accordance with their nature are properly without decision, then, 1. If the possession of a movable object was the object of the combat, the loss of the same is always the decision.
2. If the possession of ground was the object of the combat, then the decision generally lies in its loss. Still not always, only if this ground is of peculiar strength, ground which is easy to pa.s.s over, however important it may be in other respects, can be re-taken without much danger.
3. But in all other cases, when these two circ.u.mstances have not already decided the combat, therefore, particularly in case the destruction of the enemy's force is the princ.i.p.al object, the decision is reached at that moment when the conqueror ceases to feel himself in a state of disintegration, that is, of unserviceableness to a certain extent, when therefore, there is no further advantage in using the successive efforts spoken of in the twelfth chapter of the third book. On this ground we have given the strategic unity of the battle its place here.
A battle, therefore, in which the a.s.sailant has not lost his condition of order and perfect efficiency at all, or, at least, only in a small part of his force, whilst the opposing forces are, more or less, disorganised throughout, is also not to be retrieved; and just as little if the enemy has recovered his efficiency.
The smaller, therefore, that part of a force is which has really been engaged, the greater that portion which as reserve has contributed to the result only by its presence. So much the less will any new force of the enemy wrest again the victory from our hands, and that Commander who carries out to the furthest with his Army the principle of conducting the combat with the greatest economy of forces, and making the most of the moral effect of strong reserves, goes the surest way to victory. We must allow that the French, in modern times, especially when led by Buonaparte, have shown a thorough mastery in this.
Further, the moment when the crisis-stage of the combat ceases with the conqueror, and his original state of order is restored, takes place sooner the smaller the unit he controls. A picket of cavalry pursuing an enemy at full gallop will in a few minutes resume its proper order, and the crisis ceases. A whole regiment of cavalry requires a longer time. It lasts still longer with infantry, if extended in single lines of skirmishers, and longer again with Divisions of all arms, when it happens by chance that one part has taken one direction and another part another direction, and the combat has therefore caused a loss of the order of formation, which usually becomes still worse from no part knowing exactly where the other is. Thus, therefore, the point of time when the conqueror has collected the instruments he has been using, and which are mixed up and partly out of order, the moment when he has in some measure rearranged them and put them in their proper places, and thus brought the battle-workshop into a little order, this moment, we say, is always later, the greater the total force.
Again, this moment comes later if night overtakes the conqueror in the crisis, and, lastly, it comes later still if the country is broken and thickly wooded. But with regard to these two points, we must observe that night is also a great means of protection, and it is only seldom that circ.u.mstances favour the expectation of a successful result from a night attack, as on March 10, 1814, at Laon,(*) where York against Marmont gives us an example completely in place here. In the same way a wooded and broken country will afford protection against a reaction to those who are engaged in the long crisis of victory. Both, therefore, the night as well as the wooded and broken country are obstacles which make the renewal of the same battle more difficult instead of facilitating it.
(*) The celebrated charge at night upon Marmont's Corps.
Hitherto, we have considered a.s.sistance arriving for the losing side as a mere increase of force, therefore, as a reinforcement coming up directly from the rear, which is the most usual case. But the case is quite different if these fresh forces come upon the enemy in flank or rear.
On the effect of flank or rear attacks so far as they belong to Strategy, we shall speak in another place: such a one as we have here in view, intended for the restoration of the combat, belongs chiefly to tactics, and is only mentioned because we are here speaking of tactical results, our ideas, therefore, must trench upon the province of tactics.
By directing a force against the enemy's flank and rear its efficacy may be much intensified; but this is so far from being a necessary result always that the efficacy may, on the other hand, be just as much weakened. The circ.u.mstances under which the combat has taken place decide upon this part of the plan as well as upon every other, without our being able to enter thereupon here. But, at the same time, there are in it two things of importance for our subject: first, FLANK AND REAR ATTACKS HAVE, AS A RULE, A MORE FAVOURABLE EFFECT ON THE CONSEQUENCES OF THE DECISION THAN UPON THE DECISION ITSELF. Now as concerns the retrieving a battle, the first thing to be arrived at above all is a favourable decision and not magnitude of success. In this view one would therefore think that a force which comes to re-establish our combat is of less a.s.sistance if it falls upon the enemy in flank and rear, therefore separated from us, than if it joins itself to us directly; certainly, cases are not wanting where it is so, but we must say that the majority are on the other side, and they are so on account of the second point which is here important to us.
This second point IS THE MORAL EFFECT OF THE SURPRISE, WHICH, AS A RULE, A REINFORCEMENT COMING UP TO RE-ESTABLISH A COMBAT HAS GENERALLY IN ITS FAVOUR. Now the effect of a surprise is always heightened if it takes place in the flank or rear, and an enemy completely engaged in the crisis of victory in his extended and scattered order, is less in a state to counteract it. Who does not feel that an attack in flank or rear, which at the commencement of the battle, when the forces are concentrated and prepared for such an event would be of little importance, gains quite another weight in the last moment of the combat.
We must, therefore, at once admit that in most cases a reinforcement coming up on the flank or rear of the enemy will be more efficacious, will be like the same weight at the end of a longer lever, and therefore that under these circ.u.mstances, we may undertake to restore the battle with the same force which employed in a direct attack would be quite insufficient. Here results almost defy calculation, because the moral forces gain completely the ascendency. This is therefore the right field for boldness and daring.
