By many arguments and instances it can be clearly established that in their military enterprises the Romans set far more store on their infantry than on their cavalry, and trusted to the former to carry out all the chief objects which their armies were meant to effect. Among many other examples of this, we may notice the great battle which they fought with the Latins near the lake Regillus, where to steady their wavering ranks they made their horsemen dismount, and renewing the combat on foot obtained a victory. Here we see plainly that the Romans had more confidence in themselves when they fought on foot than when they fought on horseback. The same expedient was resorted to by them in many of their other battles, and always in their sorest need they found it their surest stay.
Nor are we to condemn the practice in deference to the opinion of Hannibal, who, at the battle of Cannae, on seeing the consuls make the horsemen dismount, said scoffingly, “Better still had they delivered their knights to me in chains.” For though this saying came from the mouth of a most excellent soldier, still, if we are to regard authority, we ought rather to follow the authority of a commonwealth like Rome, and of the many great captains who served her, than that of Hannibal alone. But, apart from authority, there are manifest reasons to bear out what I say. For a man may go on foot into many places where a horse cannot go; men can be taught to keep rank, and if thrown into disorder to recover form; whereas, it is difficult to keep horses in line, and impossible if once they be thrown into disorder to reform them. Moreover we find that with horses as with men, some have little courage and some much; and that often a spirited horse is ridden by a faint-hearted rider, or a dull horse by a courageous rider, and that in whatever way such disparity is caused, confusion and disorder result. Again, infantry, when drawn up in column, can easily break and is not easily broken by cavalry. This is vouched, not only by many ancient and many modern instances, but also by the authority of those who lay down rules for the government of States, who show that at first wars were carried on by mounted soldiers, because the methods for arraying infantry were not yet understood, but that so soon as these were discovered, the superiority of foot over horse was at once recognized. In saying this, I would not have it supposed that horsemen are not of the greatest use in armies, whether for purposes of observation, for harrying and laying waste the enemy’s country, for pursuing a retreating foe or helping to repulse his cavalry. But the substance and sinew of an army, and that part of it which ought constantly to be most considered, should always be the infantry. And among sins of the Italian princes who have made their country the slave of foreigners, there is none worse than that they have held these arms in contempt, and turned their whole attention to mounted troops.
