The Officer's Manual: Napoleon's Maxims of War. Emperor of the French Napoleon I

of the great rivers and principal passes, and to establish your line of communication by getting possession of the fortresses, by laying siege to them, and of the open country, by giving battle; for it is vain to expect that conquests are to be achieved without combats; although when a victory is won, they will be best maintained by uniting mildness with valor.

      MAXIM VIII.

      A general-in-chief should ask himself frequently in the day: “What should I do if the enemy’s army appeared now in my front, or on my right, or my left?” If he have any difficulty in answering these questions, his position is bad, and he should seek to remedy it.

      NOTE.

      In the campaign of 1758, the position of the Prussian army at Hohen Kirk, being commanded by the batteries of the enemy, who occupied all the heights, was eminently defective; notwithstanding, Frederick, who saw his rear menaced by the corps of Laudon, remained six days in his camp without seeking to correct his position. It would seem, indeed, that he was ignorant of his real danger: for Marshal Daun, having manœuvred during the night in order to attack by daybreak, surprised the Prussians in their lines before they were able to defend themselves, and by this means surrounded them completely.

      Frederick succeeded, however, in effecting his retreat with regularity, but not without the loss of ten thousand men, many general officers, and almost all of his artillery. If Marshal Daun had followed up his victory with greater boldness, the king of Prussia would never have been able to rally his army. On this occasion, Frederick’s good fortune balanced his imprudence.

      Marshal Saxe remarks, that there is more talent than is dreamt of in bad dispositions, if we possess the art of converting them into good ones when the favorable moment arrives. Nothing astonishes the enemy so much as this manœuvre; he has counted upon something; all his arrangements have been founded upon it accordingly—and at the moment of attack it escapes him! “I must repeat,” says the marshal, “there is nothing that so completely disconcerts an enemy as this, or leads him to commit so many errors; for it follows, that if he does not change his arrangements, he is beaten; and if he does change them, in presence of his adversary, he is equally undone.”

      It seems to me, however, that a general who should rest the success of a battle upon such a principle, would be more likely to lose than to gain by it; for if he had to deal with a skilful adversary and an alert tactician, the latter would find time to take advantage of the previous bad arrangements, before he would be able to remedy them.

      The strength of an army, like the power in mechanics, is estimated by multiplying the mass by the rapidity; a rapid march augments the morale of an army, and increases its means of victory. Press on!

      “Rapidity,” says Montécuculli, “is of importance in concealing the movements of an army, because it leaves no time to divulge the intention of its chief. It is, therefore, an advantage to attack the enemy unexpectedly, to take him off his guard, to surprise him, and let him feel the thunder before he sees the flash; but if too great celerity exhausts your troops, while, on the other hand, delay deprives you of the favorable moment, you must weigh the advantage against the disadvantage, and choose between.”

      Marshal Villars observes, that “in war everything depends upon being able to deceive the enemy; and having once gained this point, in never allowing him time to recover himself.” Villars has united practice to precept. His bold and rapid marches were almost always crowned with success.

      It was the opinion of Frederick that all wars should be short and rapid; because a long war insensibly relaxes discipline, depopulates the state, and exhausts its resources.
