Carl von Clausewitz

“ Every one knows the moral effect of a surprise, of an attack in flank or rear. Every one thinks less of the enemy’s courage as soon as he turns his back, and ventures much more in pursuit than when pursued. Every one judges of the enemy’s General by his reputed talents, by his age and experience, and shapes his course accordingly. Every one casts a scrutinising glance at the spirit and feeling of his own and the enemy’s troops. ”

“ They may, and should, therefore, defend the approaches to mountains, dykes, over marshes, river-passages, as long as possible; but when once they are broken, they should rather disperse, and continue their defence by sudden attacks, than concentrate and allow themselves to be shut up in some narrow last refuge in a regular defensive position.—However brave a nation may be, however warlike its habits, however intense its hatred of the enemy, however favourable the nature of the country, it is an undeniable fact that a people’s war cannot be kept up in an atmosphere too full of danger. ”

“ The crystals of military virtue have a greater affinity for the spirit of a corporate body than for anything else.
An Army which preserves its usual formations under the heaviest fire, which is never shaken by imaginary fears, and in the face of real danger disputes the ground inch by inch, which, proud in the feeling of its victories, never loses its sense of obedience, its respect for and confidence in its leaders, even under the depressing effects of defeat; an Army with all its physical powers, inured to privations and fatigue by exercise, like the muscles of an athlete ”

“ A swift and vigorous assumption of the offensive—the flashing sword of vengeance—is the most brilliant point in the defensive; he who does not at once think of it at the right moment, or rather he who does not from the first include this transition in his idea of the defensive will never understand the superiority of the defensive as a form of war; he will be for ever thinking only of the means which will be consumed by the enemy and gained by ourselves through the offensive, which means however depend not on tying the knot, but on untying it. ”

“ Every one is inclined to magnify the bad in some measure, and although the alarms which are thus propagated like the waves of the sea subside into themselves, still, like them, without any apparent cause they rise again. Firm in reliance on his own better convictions, the Chief must stand like a rock against which the sea breaks its fury in vain. The rôle is not easy; he who is not by nature of a buoyant disposition, or trained by experience in War, and matured in judgment, may let it be his rule to do violence to his own natural conviction by inclining from the side of fear to that of hope ”

“ Much greater is the evil which lies in the pompous retinue of technical terms—scientific expressions and metaphors, which these systems carry in their train, and which like a rabble-like the baggage of an Army broken away from its Chief—hang about in all directions. Any critic who has not adopted a system, either because he has not found one to please him, or because he has not yet been able to make himself master of one, will at least occasionally make use of a piece of one, as one would use a ruler, to show the blunders committed by a General. ”

“ Pity the warrior who is contented to crawl about in this beggardom of rules, which are too bad for genius, over which it can set itself superior, over which it can perchance make merry! What genius does must be the best of all rules, and theory cannot do better than to show how and why it is so.
Pity the theory which sets itself in opposition to the mind! It cannot repair this contradiction by any humility, and the humbler it is so much the sooner will ridicule and contempt drive it out of real life. ”

“ We see then that there are many ways to one’s object in War; that the complete subjugation of the enemy is not essential in every case; that the destruction of the enemy’s military force, the conquest of the enemy’s provinces, the mere occupation of them, the mere invasion of them—enterprises which are aimed directly at political objects—lastly, a passive expectation of the enemy’s blow, are all means which, each in itself, may be used to force the enemy’s will according as the peculiar circumstances of the case lead us to expect more from the one or the other. ”

“ Any government, therefore, which, after the loss of a great battle, only thinks how it may speedily place the nation in the lap of peace, and unmanned by the feeling of great hopes disappointed, no longer feels in itself the courage or the desire to stimulate to the utmost every element of force, completely stultifies itself in such case through weakness, and shows itself unworthy of victory, and, perhaps, just on that account, was incapable of gaining one. ”

“ So in War, through the influence of an infinity of petty circumstances, which cannot properly be described on paper, things disappoint us, and we fall short of the mark. A powerful iron will overcomes this friction; it crushes the obstacles, but certainly the machine along with them. We shall often meet with this result. Like an obelisk towards which the principal streets of a town converge, the strong will of a proud spirit stands prominent and commanding in the middle of the Art of War. ”

“ But to treat upon Strategy according to these elements would be the most unfortunate idea that could be conceived, for these elements are generally manifold, and intimately connected with each other in every single operation of War. We should lose ourselves in the most soulless analysis, and as if in a horrid dream, we should be for ever trying in vain to build up an arch to connect this base of abstractions with facts belonging to the real world. Heaven preserve every theorist from such an undertaking! ”

“ If, therefore, we imagine to ourselves a defensive, such as it should be, we must suppose it with every possible preparation of all means, with an army fit for, and inured to, war, with a general who does not wait for his adversary with anxiety from an embarrassing feeling of uncertainty, but from his own free choice, with cool presence of mind, with fortresses which do not dread a siege, and lastly, with a loyal people who fear the enemy as little as he fears them. ”

“ Here on this spot, in this very hour, to conquer the enemy is the purpose in which the plan of the War with all its threads converges, in which all distant hopes, all dim glimmerings of the future meet, fate steps in before us to give an answer to the bold question.—This is the state of mental tension not only of the Commander but of his whole Army down to the lowest waggon-driver, no doubt in decreasing strength but also in decreasing importance. ”

“ If a bloody slaughter is a horrible sight, then that is a ground for paying more respect to War, but not for making the sword we wear blunter and blunter by degrees from feelings of humanity, until some one steps in with one that is sharp and lops off the arm from our body.
We look upon a great battle as a principal decision, but certainly not as the only one necessary for a War or a campaign. Instances of a great battle deciding a whole campaign, have been frequent only in modern times, those which have decided a whole War, belong to the class of rare exceptions. ”

“ Now in War, owing to the many and powerful impressions to which the mind is exposed, and in the uncertainty of all knowledge and of all science, more things occur to distract a man from the road he has entered upon, to make him doubt himself and others, than in any other human activity.
The harrowing sight of danger and suffering easily leads to the feelings gaining ascendency over the conviction of the understanding; and in the twilight which surrounds everything a deep clear view is so difficult that a change of opinion is more conceivable and more pardonable. ”

“ Only the number needed for that security should remain in Italy, only that number should be withdrawn from the great undertaking, if we would not be unfaithful to that first maxim, Unity of plan, concentration of force. To think of conquering France by the Rhone, would be like trying to lift a musket by the point of its bayonet; but also as an auxiliary enterprise, an attack on the South of France is to be condemned, for it only raises new forces against us. Whenever an attack is made on distant provinces, interests and activities are roused, which would otherwise have lain dormant. ”

“ As long as there is yet a decision to be made, we undertake no sieges but such as are positively unavoidable. When the decision has been already given—the crisis, the utmost tension of forces, some time passed—and when, therefore, a state of rest has commenced, then the capture of strong places serves as a consolidation of the conquests made, and then they can generally be carried out, if not without effort and expenditure of force, at least without danger. In the crisis itself the siege of a fortress heightens the intensity of the crisis to the prejudice of the offensive ”

“ Fundamentally every night attack is only a more vehement form of surprise. Now at the first look of the thing such an attack appears quite pre-eminently advantageous, for we suppose the enemy to be taken by surprise, the assailant naturally to be prepared for everything which can happen. What an inequality! Imagination paints to itself a picture of the most complete confusion on the one side, and on the other side the assailant only occupied in reaping the fruits of his advantage. ”

“ 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 ”

“ The more a General is in the habit of demanding from his troops, the surer he will be that his demands will be answered. The soldier is as proud of overcoming toil, as he is of surmounting danger. Therefore it is only in the soil of incessant activity and exertion that the germ will thrive, but also only in the sunshine of victory. Once it becomes a strong tree, it will stand against the fiercest storms of misfortune and defeat, and even against the indolent inactivity of peace, at least for a time. ”

“ We shall not enter into any of the abstruse definitions of War used by publicists. We shall keep to the element of the thing itself, to a duel. War is nothing but a duel on an extensive scale. If we would conceive as a unit the countless number of duels which make up a War, we shall do so best by supposing to ourselves two wrestlers. Each strives by physical force to compel the other to submit to his will: each endeavours to throw his adversary, and thus render him incapable of further resistance.
War therefore is an act of violence intended to compel our opponent to fulfil our will. ”

“ Let it not be imagined that these are trifling or idle distinctions; we have, on the contrary, now before us one of the deepest-rooted, leading principles of war. The signification of a combat is its very soul in strategy, and we cannot too often repeat, that in strategy the leading events always proceed from the ultimate views of the two parties, as it were, from a conclusion of the whole train of ideas. This is why there may be such a difference strategically between one battle and another, that they can hardly be looked upon as the same means. ”

“ We must, therefore, decide to construe war as it is to be, and not from pure conception, but by allowing room for everything of a foreign nature which mixes up with it and fastens itself upon it—all the natural inertia and friction of its parts, the whole of the inconsistency, the vagueness and hesitation (or timidity) of the human mind: we shall have to grasp the idea that war, and the form which we give it, proceeds from ideas, feelings, and circumstances, which dominate for the moment ”

“ War does not spring up quite suddenly, it does not spread to the full in a moment; each of the two opponents can, therefore, form an opinion of the other, in a great measure, from what he is and what he does, instead of judging of him according to what he, strictly speaking, should be or should do. But, now, man with his incomplete organisation is always below the line of absolute perfection, and thus these deficiencies, having an influence on both sides, become a modifying principle. ”
