To intrench yourself in a strong position, as Fabius was wont to do, is a good method when your army is so formidable that the enemy dare not advance to attack you in your intrenchments; yet it cannot truly be said that Fabius avoided battle, but rather that he sought to give battle where he could do so with advantage. For had Hannibal desired to fight, Fabius would have waited for him and fought him. But Hannibal never dared to engage him on his own ground. So that an engagement was avoided as much by Hannibal as by Fabius, since if either had been minded to fight at all hazards the other would have been constrained to take one of three courses, that is to say, one or other of the two just now mentioned, or else to retreat. The truth of this is confirmed by numberless examples, and more particularly by what happened in the war waged by the Romans against Philip of Macedon, the father of Perseus. For Philip being invaded by the Romans, resolved not to give them battle; and to avoid battle, sought at first to do as Fabius had done in Italy, posting himself on the summit of a hill, where he intrenched himself strongly, thinking that the Romans would not venture to attack him there. But they advancing and attacking him in his intrenchments, drove him from his position; when, unable to make further resistance, he fled with the greater part of his army, and was only saved from utter destruction by the difficulty of the ground, which made it impossible for the Romans to pursue him. Philip, therefore, who had no mind to fight, encamping too near the Romans, was forced to fly; and learning from this experience that to escape fighting it was not enough for him to intrench himself on a hill, yet not choosing to shut himself up in a walled town, he was constrained to take the other alternative of keeping at a distance of many miles from the Roman legions. Accordingly, when the Romans entered one province, he betook himself to another, and when they left a province he entered it. But perceiving that by protracting the war in this way, his condition grew constantly worse, while his subjects suffered grievously, now from his own troops, at another time from those of the enemy, he at last resolved to hazard battle, and so came to a regular engagement with the Romans.
