your country, you risk your entire fortunes, without putting forth your whole strength. Nay, we find that to weaken an adversary still further, some have suffered him to make a march of several days into their country, and then to capture certain of their towns, that by leaving garrisons in these, he might reduce the numbers of his army, and so be attacked at greater disadvantage.
But now to speak my own mind on the matter, I think we should make this distinction. Either you have your country strongly defended, as the Romans had and the Swiss have theirs, or, like the Carthaginians of old and the King of France and the Italians at the present day, you have it undefended. In the latter case you must keep the enemy at a distance from your country, for as your strength lies not in men but in money, whenever the supply of money is cut off you are undone, and nothing so soon cuts off this supply as a war of invasion. Of which we have example in the Carthaginians, who, while their country was free from invasion, were able by means of their great revenues to carry on war in Italy against the Romans, but when they were invaded could not defend themselves even against Agathocles. The Florentines, in like manner, could make no head against Castruccio, lord of Lucca, when he attacked them in their own country; and to obtain protection, were compelled to yield themselves up to King Robert of Naples. And yet, after Castruccio’s death, these same Florentines were bold enough to attack the Duke of Milan in his own country, and strong enough to strip him of his dominions. Such valour did they display in distant wars, such weakness in those that were near.
But when a country is armed as Rome was and Switzerland now is, the closer you press it, the harder it is to subdue; because such states can assemble a stronger force to resist attack than for attacking others. Nor does the great authority of Hannibal move me in this instance, since resentment and his own advantage might lead him to speak as he spoke to Antiochus.
