'Is not he who immures himself to save his soul akin to the steward who buried his talents?' He developed the argument, and passed from it to talk of feats of arms, of great causes rescued, of nations liberated, of fainting right upheld and made triumphant. From broad principles his talk turned, as talk will, to details. He described encounters and actions, broad tactical movements and shrewd stratagems. And then to his amazement the subject was caught up, like a ball that is tossed, by Bellarion; and Bellarion the student was discoursing to him, the veteran of a score of campaigns and a hundred battles, upon the great art of war. He was detailing, from Thucydides, the action of the Thebans against Platæa, and condemning the foolish risk taken by Eurymachus, showing how the disastrous result of that operation should have been foreseen by a commander of any real military sense. Next he was pointing the moral to be drawn from the Spartan invasion of Attica which left the Peloponnesus uncovered to the attack of the Athenians. From that instance of disastrous impetuosity he passed to another of a different kind and of recent date in the battle of Tagliacozzo, and, revealing a close acquaintance with Primatus and Bouquet, he showed how a great army when it thrust too deeply into hostile territory must do so always at the risk of being unable to extricate itself in safety. Then from the broad field of strategy, he ran on, aglow now with a subject of his predilection, to discourse upon tactics, and chiefly to advocate and defend the more general use of infantry, to enlarge upon the value of the hedgehog for defensive purposes against cavalry, supporting his assertions by instancing the battle of Sempach and other recent actions of the Swiss. It could not be expected that a great leader like Facino, who had depended all his life upon the use of cavalry, should agree with such views as these. But the knowledge displayed by this convent-reared youngster, and the shrewd force and lucidity with which Bellarion, who had never seen a pitched battle, argued upon matters that were regarded as mysteries hidden from all but the initiates in the difficult science of arms, amazed him so profoundly that he forgot to argue at all.
