Recent opinions are likewise cited as favouring this view. Every one knows how Ferrando, king of Naples, was in his day accounted a most wise prince; and how two years before his death there came a rumour that Charles VIII of France was meditating an attack upon him; and how, after making great preparations for his defence, he sickened; and being on the point of death, among other counsels left his son Alfonso this advice, that nothing in the world should tempt him to pass out of his own territory, but to await the enemy within his frontier, and with his forces unimpaired; a warning disregarded by Alfonso, who sent into Romagna an army, which he lost, and with it his whole dominions, without a battle. Other arguments on both sides of the question in addition to those already noticed, are as follows: He who attacks shows higher courage than he who stands on his defence, and this gives his army greater confidence. Moreover, by attacking your enemy you deprive him of many opportunities for using his resources, since he can receive no aid from subjects who have been stripped of their possessions; and when an enemy is at his gates, a prince must be careful how he levies money and imposes taxes; so that, as Hannibal said, the springs which enable a country to support a war come to be dried up. Again, the soldiers of an invader, finding themselves in a foreign land, are under a stronger necessity to fight, and necessity, as has often been said, is the parent of valour. On the other hand, it may be argued that there are many advantages to be gained by awaiting the attack of your enemy. For without putting yourself much about, you may harass him by intercepting his supplies, whether of victual or of whatsoever else an army stands in need: from your better knowledge of the country you can impede his movements; and because men muster more willingly to defend their homes than to go on distant expeditions, you can meet him with more numerous forces, if defeated you can more easily repair your strength, because the bulk of your army, finding shelter at hand, will be able to save itself, and your reserves will have no distance to come. In this way you can use your whole strength without risking your entire fortunes; whereas, in leaving 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.
