Of the different kinds of troops, and of mercenaries

Having discussed in detail the characteristics of all those kinds of principalities of which I proposed at the outset to treat, and having examined to some extent the causes of their success or failure, and explained the means by which many have sought to acquire and maintain them, it remains for me now to discuss generally the means of offence and defence which such princes may have to employ, under the various circumstances above referred to.

We have said how necessary it is for a prince to lay solid foundations for his power, as without such he would inevitably be ruined. The main foundations which all states must have, whether new, or old, or mixed, are good laws and good armies. And as there can be no good laws where there are not good armies, so the laws will be apt to be good where the armies are so. I will therefore leave the question of the laws, and confine myself to that of the armies. I say, then, that the armies with which a prince defends his state are either his own, or they are mercenaries or auxiliaries, or they are mixed. Mercenary and auxiliary troops are both useless and dangerous; and if any one attempts to found his state upon mercenaries, it will never be stable or secure; for they are disunited, ambitious and without discipline – faithless and braggarts amongst friends, but amongst enemies cowards, and have neither fear of God nor good faith with men; so that the ruin of the prince who depends on them will be deferred only just so long as attack is delayed; in peace he will be spoliated by his mercenaries, and in war by his enemies. The reason of all this is, that mercenary troops are not influenced by affection, or by any other consideration except their small stipend, which is not enough to make them willing to die for you. They are ready to serve you as soldiers so long as you are at peace; but when war comes, they will either run away or march off. There is no difficulty in demonstrating the truth of this; for the present ruin of Italy can be attributed to nothing else but the fact that she has for many years depended upon mercenary armies, who for a time had some success, and seemed brave enough amongst themselves, but so soon as a foreign enemy came they showed what stuff they were made of. This was the reason why Charles VIII, King of France, was allowed to take Italy with scarcely an effort, and as it were with merely a piece of chalk. [Charles VIII had merely to send a quartermaster ahead with `a piece of chalk' to mark the houses in which the French troops were to be quartered.] Those who assert that our misfortunes were caused by our own faults speak the truth; but these faults were not such as are generally supposed to have been the cause, but those rather which I have pointed out; and as it was the princes who committed these faults, so they also suffered the penalties.

I will demonstrate more fully the unhappy consequences of employing mercenary armies. Their commanders are either competent, or they are not; if they are, then you cannot trust them, because their chief aim will always be their own aggrandisement, either by imposing upon you, who are their employer, or by oppressing others beyond your intentions; and if they are incompetent, then they will certainly hasten your ruin. If now you meet these remarks by saying that the same will be the case with every commander, whether of mercenary troops or others, I reply that inasmuch as armies are employed either by princes or by republics, the prince should always in person perform the duty of commanding his army, and a republic should send one of her own citizens to command her troops, and in case he should not be successful, then they must change him; but if he is victorious, then they must be careful to keep him within the law, so that he may not exceed his powers. Experience has shown that princes as well as republics achieve the greatest success in war when they themselves direct the movements of their own armies, whilst mercenary troops do nothing but damage; and that a republic that has armies of her own is much less easily subjected to servitude by one of her own citizens, than one that depends upon foreign troops.

Thus Rome and Sparta maintained their liberties for many centuries by having armies of their own; the Swiss are most thoroughly armed, and consequently enjoy the greatest independence and liberty. The Carthaginians, on the other hand, furnish an example of the danger of employing mercenaries, for they came very near being subjugated by them at the close of the first war with Rome, although they had appointed some of their own citizens as commanders. After the death of Epaminondas, the Thebans made Philip of Macedon commander of their army, who after having been victorious deprived the Thebans of their liberty. The Milanese, after the death of Duke Philip, employed Francesco Sforza against the Venetians; after having defeated them at Caravaggio, he combined with them to subjugate his employers,
