BATTLE OF THE METAURUS. 113
and of gaining an opportunity of outmaneuvering the Roman consul and attacking him on his march, Hannibal moved into Lucania, and then back into Apulia; he again marched down into Bruttium, and strengthened his army by a levy of recruits in that district. Nero followed him, but gave him no chance of assailing him at a disadvantage. Some partial encounters seem to have taken place; but the consul could not prevent Hannibal's junction with his Bruttian levies, nor could Hannibal gain an opportunity of surprising and crushing the consul.* Hannibal returned to his former head-quarters at Canusium, and halted there in expectation of further tidings of his brother's movements. Nero also resumed his former position in observation of the Carthaginian army.
Meanwhile, Hasdrubal had raised the siege of Placentia, and was advancing toward Ariminum on the Adriatic, and driving before him the Roman army under Porcius. Nor when the consul Livius had come up, and united the second and third armies of the north, could he make head against the invaders. The Romans still fell back before Hasdrubal, beyond Ariminum, beyond the Metaurus, and as far as the little town of Sena, to the southeast of that river. Hasdrubal was not unmindful of the necessity of acting in concert with his brother. He sent messengers to Hannibal to announce his own line of march, and to pro-

victories over Hannibal, and killing and taking his men by tens of thousands. The falsehood of all this is self-evident. If Nero could thus always beat Hannibal, the Romans would not have been in such an agony of dread about Hasdrubal as all writers describe. Indeed, we have the express testimony of Polybius that the statements which we read in Livy of Marcellus, Nero, and others gaining victories over Hannibal in Italy, must be all fabrications of Roman vanity. Polybius states, lib. xv., sec 16, that Hannibal was never defeated before the battle of Zama; and in another passage, book ix., chap. 3, he mentions that after the defeats which Hannibal inflicted on the Romans in the early years of the war, they no longer dared face his army in a pitched battle on a fair field, and yet they resolutely maintained the war. He rightly explains this by referring to the superiority of Hannibal's cavalry, the arm which gained him all his victories. By keeping within fortified lines, or close to the sides of the mountains when Hannibal approached them, the Romans rendered his cavalry ineffective; and a glance at the geography of Italy will show how an army can traverse the greater part of that country without venturing far from the high grounds.
