It is related, then, by our historian, that the Romans, after defeating on two different occasions armies of the Samnites with forces sent by them to succour the Capuans, whom they thus relieved from the war which the Samnites Were waging against them, being desirious to return to Rome, left behind two legions to defend the Capuans, that the latter might not, from being altogether deprived of their protection, once more become a prey to the Samnites. But these two legions, rotting in idleness began to take such delight therein, that forgetful of their country and the reverence due to the senate, they resolved to seize by violence the city they had been left to guard by their valour. For to them it seemed that the citizens of Capua were unworthy to enjoy advantages which they knew not how to defend. The Romans, however, getting timely notice of this design, at once met and defeated it, in the manner to be more fully noticed when I come to treat of conspiracies. Once more then, I repeat, that of all the various kinds of troops, auxiliaries are the most pernicious, because the prince or republic resorting to them for aid has no authority over them, the only person who possesses such authority being he who sends them. For, as I have said, auxiliary troops are those sent to your assistance by some other potentate, under his own flag, under his own officers, and in his own pay, as were the legions sent by the Romans to Capua. Such troops, if victorious, will for the most part plunder him by whom, as well as him against whom, they are hired to fight; and this they do, sometimes at the instigation of the potentate who sends them, sometimes for ambitious ends of their own. It was not the purpose of the Romans to violate the league and treaty which they had made with Capua; but to their soldiers it seemed so easy a matter to master the Capuans, that they were readily led into this plot for depriving them of their town and territories. Many other examples might be given to the same effect, but it is enough to mention besides this instance, that of the people of Regium, who were deprived of their city and of their lives by another Roman legion sent for their protection.
