The truth of what I affirm is shown by Titus Livius in the case of Publius Decius, who, being military tribune in the army which the consul Cornelius led against the Samnites, when the consul advanced into a defile where the Roman army were like to be shut in by the enemy, perceiving the great danger they ran, and noting, as Livius relates, a hill which rose by a steep ascent and overhung the enemy’s camp, and which, though hard of access for heavy-armed troops, presented little difficulty to troops lightly armed, turned to the consul and said:—“Seest thou, Aulus Cornelius, yonder height over above the enemy, which they have been blind enough to neglect? There, were we manfully to seize it, might we find the citadel of our hopes and of our safety.” Whereupon, he was sent by the consul with three thousand men to secure the height, and so saved the Roman army. And as it was part of his plan to make his own escape and carry off his men safely under shelter of night, Livius represents him as saying to his soldiers:—“Come with me, that, while daylight still serves, we may learn where the enemy have posted their guards, and by what exit we may issue hence.” Accordingly, putting on the cloak of a common soldier, lest the enemy should observe that an officer was making his rounds he surveyed their camp in all directions.
Now anyone who carefully studies the whole of this passage, must perceive how useful and necessary it is for a captain to know the nature of places, which knowledge had Decius not possessed he could not have decided that it would be for the advantage of the Roman army to occupy this hill; nor could he have judged from a distance whether the hill was accessible or no; and when he reached the summit and desired to return to the consul, since he was surrounded on all sides by the enemy, he never could have distinguished the path it was safe for him to take, from those guarded by the foe. For all which reasons it was absolutely essential that Decius should have that thorough knowledge which enabled him by gaining possession of this hill to save the Roman army, and to discover a path whereby, in the event of his being attacked, he and his followers might escape.

That fraud is fair in war.
Although in all other affairs it be hateful to use fraud, in the operations of war it is praiseworthy and glorious; so that he who gets the better of his enemy by fraud, is as much extolled as he who prevails by force. This appears in the judgments passed by such as have written of the lives of great warriors, who praise Hannibal and those other captains who have been most noted for acting in this way. But since we may read of many instances of such frauds, I shall not cite them here. This, however, I desire to say, that I would not have it understood that any fraud is glorious which leads you to break your plighted word, or to depart from covenants to which you have agreed; for though to do so may sometimes gain you territory and power, it can never, as I have said elsewhere, gain you glory.
The fraud, then, which I here speak of is that employed against an enemy who places no trust in you, and is wholly directed to military operations, such as the stratagem of Hannibal at the Lake of Thrasymene, when he feigned flight in order to draw the Roman consul and his army into an ambuscade; or when to escape from the hands of Fabius Maximus he fastened lights to the horns of his oxen. Similar to the above was the deceit practised by Pontius the Samnite commander to inveigle the Roman army into the Caudine Forks. For after he had drawn up his forces behind the hills, he sent out a number of his soldiers, disguised as herdsmen, to drive great herds of cattle across the plain; who being captured by the Romans, and interrogated as to where the Samnite army was, all of them, as they had been taught by Pontius, agreed in saying that it had gone to besiege Nocera: which being believed by the consuls, led them to advance within the Caudine Valley, where no sooner were they come than they were beset by the Samnites. And the victory thus won by a fraud would have been most glorious for Pontius had he but taken the advice of his father Herennius, who urged that the Romans should either be set at liberty unconditionally, or all be put to death; but that a mean course “which neither gains friends nor gets rid of foes” should be avoided. And this was sound advice, for, as has already been shown, in affairs of moment a mean course is always hurtful.
