This error is due to the craft of our captains and to the ignorance of our rulers. For the control of the armies of Italy for the last five and twenty years resting in the hands of men, who, as having no lands of their own, may be looked on as mere soldiers of fortune, these fell forthwith on contriving how they might maintain their credit by being supplied with the arms which the princes of the country were without. And as they had no subjects of their own of whom they could make use, and could not obtain constant employment and pay for a large number of foot-soldiers, and as a small number would have given them no importance, they had recourse to horsemen. For a condottiere drawing pay for two or three hundred horsemen was maintained by them in the highest credit, and yet the cost was not too great to be met by the princes who employed him. And to effect their object with more ease, and increase their credit still further, these adventurers would allow no merit or favour to be due to foot-soldiers, but claimed all for their horsemen. And to such a length was this bad system carried, that in the very greatest army only the smallest sprinkling of infantry was to be found. This, together with many other ill practices which accompanied it, has so weakened the militia of Italy, that the country has easily been trampled upon by all the nations of the North.
That it is a mistake to make more account of cavalry than of infantry, may be still more clearly seen from another example taken from Roman history. The Romans being engaged on the siege of Sora, a troop of horse a sally from the town to attack their camp; when the Roman master of the knights advancing with his own horsemen to give them battle, it so chanced that, at the very first onset, the leaders on both sides were slain. Both parties being thus left without commanders, and the combat, nevertheless, continuing, the Romans thinking thereby to have the advantage of their adversaries, alighted from horseback, obliging the enemy’s cavalry, in order to defend themselves, to do the like. The result was that the Romans had the victory. Now there could be no stronger instance than this to show the superiority of foot over horse. For while in other battles the Roman cavalry were made by their consuls to dismount in order to succour their infantry who were in distress and in need of such aid, on this occasion they dismounted, not to succour their infantry, nor to encounter an enemy contending on foot, but because they saw that though they could not prevail against the enemy fighting as horsemen against horsemen, on foot they readily might. And from this I conclude that foot-soldiers, if rightly handled, can hardly be beaten except by other soldiers fighting on foot.
