Pyrrhus, prepared for such opposition, immediately treated Tarentum as a conquered city; soldiers were quartered in the houses, the assemblies of the people and the numerous clubs (--sussitia--) were suspended, the theatre was shut, the promenades were closed, and the gates were occupied with Epirot guards. A number of the leading men were sent over the sea as hostages; others escaped the like fate by flight to Rome. These strict measures were necessary, for it was absolutely impossible in any sense to rely upon the Tarentines. It was only now that the king, in possession of that important city as a basis, could begin operations in the field.
Preparations In Rome-- Commencement Of The Conflict In Lower Italy
The Romans too were well aware of the conflict which awaited them. In order first of all to secure the fidelity of their allies or, in other words, of their subjects, the towns that could not be depended on were garrisoned, and the leaders of the party of independence, where it seemed needful, were arrested or executed: such was the case with a number of the members of the senate of Praeneste. For the war itself great exertions were made; a war contribution was levied; the full contingent was called forth from all their subjects and allies; even the proletarians who were properly exempt from obligation of service were called to arms. A Roman army remained as a reserve in the capital. A second advanced under the consul Tiberius Coruncanius into Etruria, and dispersed the forces of Volci and Volsinii. The main force was of course destined for Lower Italy; its departure was hastened as much as possible, in order to reach Pyrrhus while still in the territory of Tarentum, and to prevent him and his forces from forming a junction with the Samnites and other south Italian levies that were in arms against Rome. The Roman garrisons, that were placed in the Greek towns of Lower Italy, were intended temporarily to check the king's progress. But the mutiny of the troops stationed in Rhegium--one of the legions levied from the Campanian subjects of Rome under a Campanian captain Decius--deprived the Romans of that important town. It was not, however, transferred to the hands of Pyrrhus. While on the one hand the national hatred of the Campanians against the Romans undoubtedly contributed to produce this military insurrection, it was impossible on the other hand that Pyrrhus, who had crossed the sea to shield and protect the Hellenes, could receive as his allies troops who had put to death their Rhegine hosts in their own houses. Thus they remained isolated, in close league with their kinsmen and comrades in crime, the Mamertines, that is, the Campanian mercenaries of Agathocles, who had by similar means gained possession of Messana on the opposite side of the straits; and they pillaged and laid waste for their own behoof the adjacent Greek towns, such as Croton, where they put to death the Roman garrison, and Caulonia, which they destroyed. On the other hand the Romans succeeded, by means of a weak corps which advanced along the Lucanian frontier and of the garrison of Venusia, in preventing the Lucanians and Samnites from uniting with Pyrrhus; while the main force--four legions as it would appear, and so, with a corresponding number of allied troops, at least 50,000 strong--marched against Pyrrhus, under the consul Publius Laevinus.
Battle Near Heraclea
With a view to cover the Tarentine colony of Heraclea, the king had taken up a position with his own and the Tarentine troops between that city and Pandosia (3) (474). The Romans, covered by their cavalry, forced the passage of the Siris, and opened the battle with a vehement and successful cavalry charge; the king, who led his cavalry in person, was thrown from his horse, and the Greek horsemen, panic-struck by the disappearance of their leader, abandoned the field to the squadrons of the enemy. Pyrrhus, however, put himself at the head of his infantry, and began a fresh and more decisive engagement. Seven times the legions and the phalanx met in shock of battle, and still the conflict was undecided. Then Megacles, one of the best officers of the king, fell, and, because on this hotly-contested day he had worn the king's armour, the army for the second time believed that the king had fallen; the ranks wavered; Laevinus already felt sure of the victory and threw the whole of his cavalry on the flank of the Greeks. But Pyrrhus, marching with uncovered head through the ranks of the infantry, revived the sinking courage of his troops. The elephants which had hitherto been kept in reserve were brought up to meet the cavalry; the horses took fright at them; the soldiers, not knowing how to encounter the huge beasts, turned and fled; the masses of disordered horsemen and the pursuing elephants at length broke the compact ranks of the Roman infantry, and the elephants in concert with the excellent Thessalian cavalry wrought great slaughter among the fugitives. Had not a brave Roman soldier, Gaius Minucius, the first hastate of the fourth legion, wounded one of the elephants and thereby thrown the pursuing troops into confusion, the Roman army would have been extirpated; as it was, the remainder of the Roman troops succeeded in retreating across the Siris. Their loss was great; 7000 Romans were found by the victors dead or wounded on the field of battle, 2000 were brought in prisoners; the Romans themselves stated their loss, including probably the wounded carried off the field, at 15,000 men. But Pyrrhus's army had suffered not much less: nearly 4000 of his best soldiers strewed the field of battle, and several of his ablest captains had fallen. Considering that his loss fell chiefly on the veteran soldiers who were far more difficult to be replaced than the Roman militia, and that he owed his victory only to the surprise produced by the attack of the elephants which could not be often repeated, the king, skilful judge of tactics as he was, may well at an after period have described this victory as resembling a defeat; although he was not so foolish as to communicate that piece of self-criticism to the public--as the Roman poets afterwards invented the story--in the inscription of the votive offering presented by him at Tarentum.
