And if it be urged that whoever is armed will act in the same way, whether mercenary or not, I reply that when arms have to be resorted to, either by a prince or a republic, then the prince ought to go in person and perform the duty of a captain; the republic has to send its citizens, and when one is sent who does not turn out satisfactorily, it ought to recall him, and when one is worthy, to hold him by the laws so that he does not leave the command. And experience has shown princes and republics, single-handed, making the greatest progress, and mercenaries doing nothing except damage; and it is more difficult to bring a republic, armed with its own arms, under the sway of one of its citizens than it is to bring one armed with foreign arms. Rome and Sparta stood for many ages armed and free. The Switzers are completely armed and quite free. Of ancient mercenaries, for example, there are the Carthaginians, who were oppressed by their mercenary soldiers after the first war with the Romans, although the Carthaginians had their own citizens for captains. After the death of Epaminondas, Philip of Macedon was made captain of their soldiers by the Thebans, and after victory he took away their liberty. Duke Filippo being dead, the Milanese enlisted Francesco Sforza against the Venetians, and he, having overcome the enemy at Caravaggio,[2] allied himself with them to crush the Milanese, his masters. His father, Sforza, having been engaged by Queen Johanna[3] of Naples, left her unprotected, so that she was forced to throw herself into the arms of the King of Aragon, in order to save her kingdom. And if the Venetians and Florentines formerly extended their dominions by these arms, and yet their captains did not make themselves princes, but have defended them, I reply that the Florentines in this case have been favoured by chance, for of the able captains, of whom they might have stood in fear, some have not conquered, some have been opposed, and others have turned their ambitions elsewhere. One who did not conquer was Giovanni Acuto,[4] and since he did not conquer his fidelity cannot be proved; but every one will acknowledge that, had he conquered, the Florentines would have stood at his discretion. Sforza had the Bracceschi always against him, so they watched each other. Francesco turned his ambition to Lombardy; Braccio against the Church and the kingdom of Naples. But let us come to that which happened a short while ago. The Florentines appointed as their captain Pagolo Vitelli, a most prudent man, who from a private position had risen to the greatest renown. If this man had taken Pisa, nobody can deny that it would have been proper for the Florentines to keep in with him, for if he became the soldier of their enemies they had no means of resisting, and if they held to him they must obey him. The Venetians, if their achievements are considered, will be seen to have acted safely and
