Croesus, king of Lydia, after showing Solon the Athenian much besides, at last displayed to him the boundless riches of his treasure-house, and asked him what he thought of his power. Whereupon Solon answered that he thought him no whit more powerful in respect of these treasures, for as war is made with iron and not with gold, another coming with more iron might carry off his gold. After the death of Alexander the Great a tribe of Gauls, passing through Greece on their way into Asia, sent envoys to the King of Macedonia to treat for terms of accord; when the king, to dismay them by a display of his resources, showed them great store of gold and silver. But these barbarians, when they saw all this wealth, in their greed to possess it, though before they had looked on peace as settled, broke off negotiations; and thus the king was ruined by those very treasures he had amassed for his defence. In like manner, not many years ago, the Venetians, with a full treasury, lost their whole dominions without deriving the least advantage from their wealth.
I maintain, therefore, that it is not gold, as is vulgarly supposed, that is the sinews of war, but good soldiers; or while gold by itself will not gain you good soldiers, good soldiers may readily get you gold. Had the Romans chosen to make war with gold rather than with iron all the treasures of the earth would not have sufficed them having regard to the greatness of their enterprises and the difficulties they had to overcome in carrying them out. But making their wars with iron they never felt any want of gold; for those who stood in fear of them brought gold into their camp.
And supposing it true that the Spartan king was forced by lack of money to risk the chances of a battle, it only fared with him in respect of money as it has often fared with others from other causes; since we see that where an army is in such straits for want of victual that it must either fight or perish by famine, it will always fight, as being the more honourable course and that on which fortune may in some way smile. So, too, it has often happened that a captain, seeing his enemy about to be reinforced, has been obliged either to trust to fortune and at once deliver battle, or else, waiting till the reinforcement is complete, to fight then, whether he will or no, and at whatever disadvantage. We find also, as in the case of Hasdrubal when beset, in the March of Ancona, at once by Claudius Nero and by the other Roman consul, that a captain, when he must either fight or fly, will always fight, since it will seem to him that by this course, however hazardous, he has at least a chance of victory, while by the other his ruin is certain.
