On the Suspension of the Act in Warfare


IF one looks at war as an act of mutual destruction, we must of necessity imagine both parties in a general way as making some progress; but at the same time, as regards the existing moment, we must almost just as necessarily suppose the one party in a state of expectation, and only the other actually advancing, for circumstances can never be exactly the same on both sides, or continue so. In time a change must ensue, from which it follows that the present moment is more favourable to one side than the other. Now if we suppose that both commanders have a full knowledge of this circumstance, then the one has a motive for action, which at the same time is a motive for the other to wait; therefore, according to this it cannot be for the interest of both at the same time to advance, nor can waiting be for the interest of both at the same time. This opposition of interest as regards the object is not deduced here from the principle of general polarity, and therefore is not in opposition to the argument in the fifth chapter of the second book; it depends on the fact that here in reality the same thing is at once an incentive or motive to both commanders, namely the probability of improving or impairing their position by future action.

But even if we suppose the possibility of a perfect equality of circumstances in this respect, or if we take into account that through imperfect knowledge of their mutual position such an equality may appear to the two commanders to subsist, still the difference of political objects does away with this possibility of suspension. One of the parties must of necessity be assumed politically to be the aggressor, because no war could take place from defensive intentions on both sides. But the aggressor has the positive object, the defender merely a negative one. To the first then belongs the positive action, for it is only by that means that he can attain the positive object; therefore, in cases where both parties are in precisely similar circumstances, the aggressor is called upon to act by virtue of his positive object.

Therefore, according to this manner of viewing it, a suspension in the act of warfare, strictly speaking, is in contradiction with the nature of the thing; because two armies, being two incompatible elements, should destroy one another unremittingly, just as fire and water can never put themselves in equilibrum, but act and react upon one another, until one quite disappears. What would be said of two wrestlers who remained clasped round each other for hours without making a movement. Action in war, therefore, like that of a clock which is wound up, should go on running down in regular motion.—But wild as is the nature of war it still wears the chains of human weakness, and the contradiction we see here, that man seeks and creates dangers which he fears at the same time will astonish no one.

If we cast a glance at military history in general, there we find so much the opposite of an incessant advance towards the aim, that standing still and doing nothing is quite plainly the normal condition of an army in the midst of war, acting, the exception. This must almost raise a doubt as to the correctness of our conception. But if military history has this effect by the great body of its events, so also the latest series of them redeems our view. The war of the French Revolution only shows too plainly its reality, and only proves too plainly its necessity. In that war, and especially in the campaigns of Buonaparte, the conduct of war attained to that unlimited degree of energy which we have represented as the natural law of the element. This degree is therefore possible, and if it is possible then it is necessary.

How could any one in fact justify in the eyes of reason the expenditure of forces in war, if acting was not the the object? The baker only heats his oven if he has bread to put into it; the horse is only yoked to the carriage if we mean to drive; why then make the enormous effort of a War if we look for nothing else by it but like efforts on the part of the enemy?

So much in justification of the general principle: now as to its modifications, as far as they lie in the nature of the thing and are independent of special cases.

There are three causes to be noticed here, which appear as innate counterpoises and prevent the over-rapid or uncontrollable movement of the wheel-work.

The first, which produces a constant tendency to delay, and is thereby a retarding principle, is the natural timidity and want of resolution in the human mind, a kind of power of gravity in the moral world, but which is produced not by attractive, but by repellent forces, that is to say, by dread of danger and responsibility.

In the burning element of War, ordinary natures appear to become heavier; the impulsion given must therefore be stronger and more frequently repeated if the motion is to be a continuous one. The mere idea of the object for which arms have been taken up is seldom sufficient to overcome this resistant force, and if a warlike enterprising spirit is not at the head, who feels himself in war in his natural element, as much as a fish in the ocean, or if there is not the pressure from above of some great responsibility, then standing still will be the order of the day, and progress will be the exception.

The second cause is the imperfection of human perception and judgment, which is greater in war than anywhere, because a person hardly knows exactly his own position from one moment to another, and can only conjecture on slight grounds that of the enemy, which is purposely concealed; this often gives rise to the case of both parties looking upon one and the same object as advantageous for them, while in reality the interest of one must preponderate; thus then each may think he acts wisely by waiting another moment, as we have already said in the fifth chapter of the second book.

The third cause which catches hold, like a ratchet wheel in machinery, from time to time producing a complete stand still, is the greater strength of the defensive form. A may feel too weak to attack B, from which it does not follow that B, is strong enough for an attack on A. The addition of strength, which the defensive gives is not merely lost by assuming the offensive, but also passes to the enemy just as, figuratively expressed, the difference of a+b and a-b is equal to 2b. Therefore it may so happen that both parties, at one and the same time, not only feel themselves too weak to attack, but also are so in reality.

Thus even in the midst of the art of war itself, anxious sagacity and the apprehension of too great danger find vantage ground, by means of which they can exert their power, and tame the elementary impetuosity of war.

However, at the same time these causes without an exaggeration of their effect, would hardly explain the long states of inactivity which took place in military operations, in former times, in wars undertaken about interests of no great importance, and in which inactivity consumed nine-tenths of the time that the troops remained under arms. This feature in these wars, is to be traced principally to the influence which the demands of the one party, and the condition, and feeling of the other, exercised over the conduct of the operations, as has been already observed in the chapter on the essence and object of war.

These things may obtain such a preponderating influence as to make of war a half-and-half thing. A war is often nothing more than an armed neutrality, or a menacing attitude to support negotiations or an attempt to gain some small advantage by small exertions, and then to wait the tide of circumstances, or a disagreeable treaty obligation, which is fulfilled in the most niggardly way possible.

In all these cases in which the impulse given by interest is slight, and the principle of hostility feeble, in which there is no desire to do much, and also not much to dread from the enemy; in short, where no powerful motives press and drive, cabinets will not risk much in the game; hence this tame mode of carrying on war, in which the hostile spirit of real war is laid in irons.

The more war becomes in this manner a half-and-half thing, so much the more its theory becomes destitute of the necessary firm pivots and buttresses for its reasoning; the necessary is constantly diminishing, the accidental constantly increasing.

Nevertheless in this kind of warfare, there is also a certain shrewdness, indeed, its action is perhaps more diversified, and more extensive than in the other. Hazard played with rouleaux of gold seems changed into a game of commerce with groschen. And on this field, where the conduct of war spins out the time with a number of small flourishes, with skirmishes at outposts, half in earnest half in jest, with long dispositions which end in nothing, with positions and marches, which afterwards are designated as skilful only because their infinitesimally small causes are lost, and common sense can make nothing of them, here just on this very field many theorists find the real art of war at home: in these feints, parades, half and quarter thrusts of former wars, they find the aim of all theory, the supremacy of mind over matter, and modern wars appear to them mere savage fisticuffs, from which nothing is to be learnt, and which must be regarded as mere retrograde steps towards barbarism. This opinion is as frivolous as the objects to which it relates. Where great forces and great passions are wanting, it is certainly easier for a practised dexterity to show its game; but is then the command of great forces, the steerage in storm and tempest, not in itself a higher exercise of the intelligent faculties? Is then that kind of conventional sword-exercise not comprised in and belonging to the other mode of conducting war? Does it not bear the same relation to it as the motions upon a ship to the motion of the ship itself? Truly it can take place only under the tacit condition that the adversary does no better. And can we tell, how long he may choose to respect those conditions? Has not then the French revolution fallen upon us in the midst of the fancied security of our old system of war, and driven us from Chalons to Moscow? And did not Frederick the Great in like manner surprise the Austrians reposing in their ancient habits of war, and make their monarchy tremble? Woe to the cabinet which, with a shilly-shally policy, and a routine-ridden military system, meets with an adversary who, like the rude element, knows no other law than that of his intrinsic force. Every deficiency in energy and exertion is then a weight in the scales in favour of the enemy; it is not so easy then to change from the fencing posture into that of an athlete, and a slight blow is often sufficient to knock down the whole.

The result of all the causes now adduced is, that the hostile action of a campaign does not progress by a continuous, but by an intermittent movement, and that, therefore, between the separate bloody acts, there is a period of watching, during which both parties fall into the defensive, and also that usually a higher object causes the principle of aggression to predominate on one side, and thus leaves it in general in an advancing position, by which then its proceedings become modified in some degree.
