On Auxiliary, Mixed, and Citizen Soldiers
Auxiliary troops, the other kind of worthless armies, are those that arrive when you call a powerful man to bring his forces to your aid and defence, as was done in recent times by Pope Julius, who, having witnessed in the campaign of Ferrara the sad showing of his mercenary soldiers, turned to auxiliary soldiers and made an agreement with Ferdinand, King of Spain, that he assist him with his troops and his armies. These soldiers can be useful and good in themselves, but for the man who summons them they are almost always harmful; for, if they lose you are defeated; if they win you end up their prisoner. And although ancient histories are full of such instances, nevertheless I am unwilling to leave unexamined this recent example of Pope Julius II, whose policy could not have been more poorly considered, for, in wanting to take Ferrara, he threw himself completely into the hands of a foreigner. But his good fortune brought about a third development so that he did not gather the fruit of his poor decision: for after his auxiliaries were routed at Ravenna, the Swiss rose up and, to the consternation of Pope Julius as well as everyone else, chased out the victors. Thus, he was neither taken prisoner by his enemies, since they had fled, nor by his auxiliaries, since he triumphed with arms other than theirs. And'the Florentines, completely unarmed, hired ten thousand French soldiers to take Pisa; such a plan endangered them more than any of their previous predicaments. The emperor of Constantinople,* in order to oppose his neighbours, brought ten thousand Turkish troops into Greece, who, when the war was over, did not want to leave; this was the beginning of Greek servitude under the infidel.
Anyone, therefore, who does not wish to conquer should make use of these soldiers, for they are much more dangerous than mercenary troops. Because with them defeat is certain: they are completely united and all under the command of
