NOTE: This version of Carl von Clausewitz's On War is the long-obsolete J.J. Graham translation of Clausewitz's Vom Kriege (1832) published in London in 1873. The 1976/84 Howard/Paret version is the  standard translation today; for the most accurate text one should always consult the 1943 Jolles translation. Consider the more modern versions and other relevant books shown below.

Ends in War More Precisely Defined—(Continued)

Limited Object


IN the preceding chapter we have said that, under the expression "overthrow of the enemy," we understand the real absolute aim of the "act of war;" now we shall see what remains to be done when the conditions under which this object might be attained do not exist.

These conditions presuppose a great physical or moral superiority, or a great spirit of enterprise, an innate propensity to extreme hazards. Now where all this is not forthcoming, the aim in the act of war can only be of two kinds; either the conquest of some small or moderate portion of the enemy's country, or the defence of our own until better times; this last is the usual case in defensive war.

Whether the one or the other of these aims is of the right kind, can always be settled by calling to mind the expression used in reference to the last. The waiting till more favourable times implies that we have reason to expect such times hereafter, and this waiting for, that is, defensive war, is always based on this prospect; on the other hand, offensive war, that is, the taking advantage of the present moment, is always commanded when the future holds out a better prospect, not to ourselves, but to our adversary.

The third case, which is probably the most common, is when neither party has anything definite to look for from the future, when therefore it furnishes no motive for decision. In this case, the offensive war is plainly imperative upon him who is politically the aggressor, that is, who has the positive motive; for he has taken up arms with that object, and every moment of time which is lost without any good reason, is so much lost time for him.

We have here decided for offensive or defensive war on grounds which have nothing to do with the relative forces of the combatants respectively, and yet it may appear that it would be nearer right to make the choice of the offensive or defensive chiefly dependent on the mutual relations of combatants in point of military strength; our opinion is, that in doing so we should just leave the right road. The logical correctness of our simple argument no one will dispute; we shall now see whether in the concrete case it leads to the contrary.

Let us suppose a small State which is involved in a contest with a very superior power, and foresees that with each year its position will become worse: should it not, if war is inevitable, make use of the time when its situation is furthest from the worst? Then it must attack, not because the attack in itself ensures any advantages—it will rather increase the disparity of forces—but because this State is under the necessity of either bringing the matter completely to an issue before the worst time arrives, or of gaining, at least, in the mean time, some advantages which it may hereafter turn to account. This theory cannot appear absurd. But if this small State is quite certain that the enemy will advance against it, then, certainly, it can and may make use of the defensive against its enemy to procure a first advantage; there is then at any rate no danger of losing time.

If, again, we suppose a small State engaged in war with a greater, and that the future has no influence on their decisions, still, if the small State is politically the assailant, we demand of it also that it should go forward to its object.

If it has had the audacity to propose to itself a positive end in the face of superior numbers, then it must also act, that is, attack the foe, if the latter does not save it the trouble. Waiting would be an absurdity; unless at the moment of execution it has altered its political resolution, a case which very frequently occurs, and contributes in no small degree to give wars an indefinite character.

These considerations on the limited object apply to its connection both with offensive war and defensive war; we shall consider both in separate chapters. But we shall first turn our attention to another phase.

Hitherto we have deduced the modifications in the object of war solely from intrinsic reasons. The nature of the political view (or design) we have only taken into consideration in so far as it is or is not directed at something positive. Everything else in the political design is in reality something extraneous to war; but in the second chapter of the first book (End and Means in War) we have already admitted that the nature of the political object, the extent of our own or the enemy's demand, and our whole political relation practically have a most decisive influence on the conduct of the war, and we shall therefore devote the following chapter to that subject specially.
