On War

Carl von Clausewitz · c. 1816–1830 (work compiled/rewritten across these years) primary

passage 505 of 539 · BOOK I. ON THE NATURE OF WAR > CHAPTER IV. Ends in War More Precisely Defined (6/6)

in brief
Clausewitz returns to the role of defense, arguing that a defensive posture with a positive principle seeks to change into attack, and he uses the defensive opening of the Russian campaign of 1812 as a real example.

of the assailant. But as the political relations may change from year to year, therefore, on that account alone, many cases may happen which are exceptions to this general truth.

It may appear perhaps as if we had left our general point of view, and had nothing in our eye except offensive war; but it is not so by any means. Certainly, he who can set before himself the complete overthrow of the enemy as his object, will not easily be reduced to take refuge in the defensive, the immediate object of which is only to keep possession; but as we stand by the declaration throughout, that a defensive without any positive principle is a contradiction in strategy as well as in tactics, and therefore always come back to the fact that every defensive, according to its strength, will seek to change to the attack as soon as it has exhausted the advantages of the defensive, so therefore, however great or small the defence may be, we still also include in it contingently the overthrow of the enemy as an object which this attack may have, and which is to be considered as the proper object of the defensive, and we say that there may be cases in which the assailant, notwithstanding he has in view such a great object, may still prefer at first to make use of the defensive form. That this idea is founded in reality is easily shown by the campaign of 1812. The Emperor Alexander in engaging in the war did not perhaps think of ruining his enemy completely, as was done in the sequel; but is there anything which makes such an idea impossible? And yet, if so, would it not still remain very natural that the Russians began the war on the defensive?
