  73. When the two forces came within distance, the light-armed troops in front of the two armies closed with each other. In this part of the battle the Romans were in many respects at a disadvantage, while the Carthaginians had everything in their favour. For the Roman spearmen had been on hard service ever since daybreak, and had expended most of their weapons in the engagement with the Numidians, while those weapons which were left had become useless from being long wet. Nor were the cavalry, or indeed the whole army, any better off in these respects. The case of the Carthaginians was exactly the reverse: they had come on the field perfectly sound and fresh, and were ready and eager for every service required of them. As soon, therefore, as their advanced guard had retired again within their lines, and the heavy-armed soldiers were engaged, the cavalry on the two wings of the Carthaginian army at once charged the enemy with all the effect of superiority in numbers, and in the condition both of men and horses secured by their freshness when they started. The Roman cavalry on the contrary retreated: and the flanks of the line being thus left unprotected, the Carthaginian spearmen and the main body of the Numidians, passing their own advanced guard, charged the Roman flanks: and, by the damage which they did them, prevented them from keeping up the fight with the troops on their front. The heavy-armed soldiers, however, who were in the front rank of both armies, and in the centre of that, maintained an obstinate and equal fight for a considerable time.

  74. Just then the Numidians, who had been lying in ambush, left their hiding-place, and by a sudden charge on the centre of the Roman rear produced great confusion and alarm throughout the army. Finally both the Roman wings, being hard pressed in front by the elephants, and on both flanks by the light-armed troops of the enemy, gave way, and in their flight were forced upon the river behind them. After this, while the centre of the Roman rear was losing heavily, and suffering severely from the attack of the Numidian ambuscade, their front, thus driven to bay, defeated the Celts and a division of Africans, and, after killing a large number of them, succeeded in cutting their way through the Carthaginian line. Then seeing that their wings had been forced off their ground, they gave up all hope of relieving them or getting back to their camp, partly because of the number of the enemy’s cavalry, and partly because they were hindered by the river and the pelting storm of rain which was pouring down upon their heads. They therefore closed their ranks, and made their way safely to Placentia, to the number of ten thousand. Of the rest of the army the greater number were killed by the elephants and cavalry on the bank of the Trebia; while those of the infantry who escaped, and the greater part of the cavalry, managed to rejoin the ten thousand mentioned above, and arrived with them at Placentia. Meanwhile the Carthaginian army pursued the enemy as far as the Trebia; but being prevented by the storm from going farther, returned to their camp. They regarded the result of the battle with great exultation, as a complete success; for the loss of the Iberians and Africans had been light, the heaviest having fallen on the Celts. But from the rain and the snow which followed it, they suffered so severely, that all the elephants except one died, and a large number of men and horses perished from the cold.

  75. Fully aware of the nature of his disaster, but wishing to conceal its extent as well as he could from the people at home, Tiberius sent messengers to announce that a battle had taken place, but that the storm had deprived them of the victory. For the moment this news was believed at Rome; but when soon afterwards it became known that the Carthaginians were in possession of the Roman camp, and that all the Celts had joined them: while their own troops had abandoned their camp, and, after retiring from the field of battle, were all collected in the neighbouring cities; and were besides being supplied with necessary provisions by sea up the Padus, the Roman people became only too certain of what had really happened in the battle. It was a most unexpected reverse, and it forced them at once to urge on with energy the remaining preparations for the war. They reinforced those positions which lay in the way of the enemy’s advance; sent legions to Sardinia and Sicily, as well as garrisons to Tarentum, and other places of strategical importance; and, moreover, fitted out a fleet of sixty quinqueremes. The Consuls designate, Gnaeus Servilius and Gaius Flaminius, were collecting the allies and enrolling the citizen legions, and sending supplies to Ariminum and Etruria, with a view of going to the seat of war by those two routes. They sent also to king Hiero asking for reinforcements, who sent them five hundred Cretan archers and a thousand peltasts. In fact they pushed on their preparations in every direction with energy. For the Roman people are most formidable, collectively and individually, when they have real reason for alarm.

  76. While these events were happening in Italy, Gnaeus Cornelius Scipio, who had been left by his brother Publius in command of the fleet, setting sail from the mouth of the Rhone, came to land with his whole squadron at a place in Iberia called Emporium. Starting from this town, he made descents upon the coast, landing and besieging those who refused to submit to him along the seaboard as far as the Iber; and treating with every mark of kindness those who acceded to his demands, and taking all the precautions he could for their safety. When he had garrisoned those towns on the coast that submitted, he led his whole army inland, having by this time a not inconsiderable contingent of Iberian allies; and took possession of the towns on his line of march, some by negotiation and some by force of arms. The Carthaginian troops which Hannibal had left in that district under the command of Hanno, lay entrenched to resist him under the walls of a town called Cissa.

  Defeating this army in a pitched battle, Gnaeus not only got possession of a rich booty, for the whole baggage of the army invading Italy had been left under its charge, but secured the friendly alliance of all the Iberian tribes north of the Iber, and took both Hanno, the general of the Carthaginians, and Andobales, the general of the Iberians, prisoners. The latter was despot of central Iberia, and had always been especially inclined to the side of Carthage.

  Immediately he learnt what had happened, Hasdrubal crossed the Iber to bring aid. There he ascertained that the Roman troops left in charge of the fleet had abandoned all precautions, and were trading on the success of the land forces to pass their time in ease. He therefore took with him eight thousand infantry and one thousand cavalry of his own army, and finding the men of the fleet scattered about the country, he killed a great many of them and forced the rest to fly for refuge to their ships. He then retired across the Iber again, and employed himself in fortifying and garrisoning the posts south of the river, taking up his winter quarters at New Carthage. When Gnaeus rejoined his fleet, he punished the authors of the disaster according to the Roman custom; and then collected his land and sea forces together in Tarraco, and there took up his winter quarters; and by dividing the booty equally between his soldiers, inspired them at once with affection towards himself and eagerness for future service. Such was the course of the Iberian campaign.

  77. At the beginning of the following spring, Gaius Flaminius marched his army through Etruria, and pitched his camp at Arretium; while his colleague Gnaeus Servilius on the other hand went to Ariminum, to await the advance of the enemy in that direction.

  Passing the winter in the Celtic territory, Hannibal kept his Roman prisoners in close confinement, supplying them very sparingly with food; while he treated their allies with great kindness from the first, and finally called them together and addressed them, alleging, “that he had not come to fight against them, but against Rome in their behalf; and that, therefore, if they were wise, they would attach themselves to him: because he had come to restore freedom to the Italians, and to assist them to recover their cities and territory which they had severally lost to Rome.” With these words he dismissed them without ransom to their own homes: wishing by this policy to attract the inhabitants of Italy to his cause, and to alienate their affections from Rome, and to awaken the resentment of all those who considered themselves to have suffered by the loss of harbours or cities under the Roman rule.

  78. Wh
ile he was in these winter quarters also he practised a ruse truly Punic. Being apprehensive that from the fickleness of their character, and the newness of the tie between himself and them, the Celts might lay plots against his life, he caused a number of wigs to be made for him, suited in appearance to men of various ages; and these he constantly varied, changing at the same time his clothes also to harmonise with the particular wig which he wore. He thus made it hard to recognise him, not only for those who met him suddenly, but even for his intimates. But seeing that the Celts were discontented at the lengthened continuance of the war within their borders, and were in a state of restless hurry to invade the enemy’s territory, — on the pretence of hatred for Rome, but in reality from love of booty, — he determined to break up his camp as soon as possible, and satisfy the desires of his army. Accordingly as soon as the change of season set in, by questioning those who were reputed to know the country best, he ascertained that the other roads leading into Etruria were long and well known to the enemy, but that the one which led through the marshes was short, and would bring them upon Flaminius as a surprise. This was what suited his peculiar genius, and he therefore decided to take this route. But when the report was spread in his army that the general was going to lead them through some marshes, every soldier felt alarmed at the idea of the quagmires and deep sloughs which they would find on this march.

  79. But after a careful inquiry as to what part of the road was firm or boggy, Hannibal broke up his camp and marched out. He placed the Libyans and Iberians and all his best soldiers in the van, and the baggage within their lines, that there might be plenty of provisions for their immediate needs. Provisions for the future he entirely neglected. Because he calculated that on reaching the enemy’s territory, if he were beaten he should not require them, and if he were victorious he would find abundance in the open country. Behind this vanguard he placed the Celts, and in the rear of all the cavalry. He entrusted the command of the rear-guard to his brother Mago, that he might see to the security of all, and especially to guard against the cowardice and impatience of hard labour which characterised the Celts; in order that, if the difficulty of the route should induce them to turn back, he might intercept them by means of the cavalry and force them to proceed. In point of fact, the Iberians and Libyans, having great powers of endurance and being habituated to such fatigues, and also because when they marched through them the marshes were fresh and untrodden, accomplished their march with a moderate amount of distress: but the Celts advanced with great difficulty, because the marshes were now disturbed and trodden into a deep morass: and being quite unaccustomed to such painful labours, they bore the fatigue with anger and impatience; but were hindered from turning back by the cavalry in their rear. All however suffered grievously, especially from the impossibility of getting sleep on a continuous march of four days and three nights through a route which was under water: but none suffered so much, or lost so many men, as the Celts. Most of his beasts of burden also slipping in the mud fell and perished, and could then only do the men one service: they sat upon their dead bodies, and piling up baggage upon them so as to stand out above the water, they managed to get a snatch of sleep for a short portion of the night. Another misfortune was that a considerable number of the horses lost their hoofs by the prolonged march through bog. Hannibal himself was with difficulty and much suffering got across riding on the only elephant left alive, enduring great agony from a severe attack of ophthalmia, by which he eventually lost the sight of one eye, because the time and the difficulties of the situation did not admit of his waiting or applying any treatment to it.

  80. Having crossed the marshes in this unexpected manner, Hannibal found Flaminius in Etruria encamped under the walls of Arretium. For the present he pitched his camp close to the marshes, to refresh his army, and to investigate the plans of his enemies and the lie of the country in his front. And being informed that the country before him abounded in wealth, and that Flaminius was a mere mob-orator and demagogue, with no ability for the actual conduct of military affairs, and was moreover unreasonably confident in his resources; he calculated that, if he passed his camp and made a descent into the district beyond, partly for fear of popular reproach and partly from a personal feeling of irritation, Flaminius would be unable to endure to watch passively the devastation of the country, and would spontaneously follow him wherever he went; and being eager to secure the credit of a victory for himself, without waiting for the arrival of his colleague, would give him many opportunities for an attack.

  81. And in making these calculations Hannibal showed his consummate prudence and strategical ability. For it is mere blind ignorance to believe that there can be anything of more vital importance to a general than the knowledge of his opponent’s character and disposition. As in combats between individuals or ranks, he who would conquer must observe carefully how it is possible to attain his object, and what part of his enemy appears unguarded or insufficiently armed, — so must a commander of an army look out for the weak place, not in the body, but in the mind of the leader of the hostile force. For it has often happened before now that from mere idleness and lack of energy, men have let not only the welfare of the state, but even their private fortunes fall to ruin: some are so addicted to wine that they cannot sleep without bemusing their intellects with drink; and others so infatuated in their pursuit of sensual pleasures, that they have not only been the ruin of their cities and fortunes, but have forfeited life itself with disgrace. In the case of individuals, however, cowardice and sloth bring shame only on themselves; but when it is a commander-in-chief that is concerned, the disaster affects all alike and is of the most fatal consequence. It not only infects the men under him with an inactivity like his own; but it often brings absolute dangers of the most serious description upon those who trust such a general. For rashness, temerity, and uncalculating impetuosity, as well as foolish ambition and vanity, give an easy victory to the enemy. And are the source of numerous dangers to one’s friends: for a man who is the prey of such weaknesses falls the easiest victim to every stratagem, ambush or ruse. The general then who can gain a clear idea of his opponent’s weaknesses, and direct his attack on the point where he is most open to it, will very soon be the victor in the campaign. For as a ship, if you deprive it of its steerer, falls with all its crew into the hands of the enemy; so, in the case of an army in war, if you outwit or out-manœuvre its general, the whole will often fall into your hands.

  82. Nor was Hannibal mistaken in his calculations in regard to Flaminius. For no sooner had he left the neighbourhood of Faesulae, and, advancing a short way beyond the Roman camp, made a raid upon the neighbouring country, than Flaminius became excited, and enraged at the idea that he was despised by the enemy: and as the devastation of the country went on, and he saw from the smoke that rose in every direction that the work of destruction was proceeding, he could not patiently endure the sight. Some of his officers advised that they should not follow the enemy at once nor engage him, but should act on the defensive, in view of his great superiority in cavalry; and especially that they should wait for the other Consul, and not give battle until the two armies were combined. But Flaminius, far from listening to their advice, was indignant at those who offered it; and bade them consider what the people at home would say at the country being laid waste almost up to the walls of Rome itself, while they remained encamped in Etruria on the enemy’s rear. Finally, with these words, he set his army in motion, without any settled plan of time or place; but bent only on falling in with the enemy, as though certain victory awaited him. For he had managed to inspire the people with such confident expectations, that the unarmed citizens who followed his camp in hope of booty, bringing chains and fetters and all such gear, were more numerous than the soldiers themselves.

  Meanwhile Hannibal was advancing on his way to Rome through Etruria, keeping the city of Cortona and its hills on his left, and the Thrasymene lake on his right; and as he marched, he burned and wasted the country with a
view of rousing the wrath of the enemy and tempting him to come out. And when he saw Flaminius get well within distance, and observed that the ground he then occupied was suited to his purpose, he bent his whole energies on preparing for a general engagement.

  83. The route which he was following led through a low valley enclosed on both sides by long lines of lofty hills. Of its two ends, that in front was blocked by an abrupt and inaccessible hill, and that on the rear by the lake, between which and the foot of the cliff there is only a very narrow defile leading into this valley. Making his way to the end of the valley along the bank of the lake, Hannibal posted himself with the Spanish and Libyan troops on the hill immediately in front of him as he marched, and pitched a camp on it; but sent his Balearic slingers and light-armed troops by a détour, and stationed them in extended order under the cover of the hills to the right of the valley; and by a similar détour placed the Gauls and cavalry under the cover of hills to the left, causing them also to extend their line so far as to cover the entrance of the defile running between the cliff and lake into the valley.

  Having made these preparations during the night, and having thus enclosed the valley with ambuscades, Hannibal remained quiet. In pursuit of him came Flaminius, in hot haste to close with the enemy. It was late in the evening before he pitched his camp on the border of the lake; and at daybreak next morning, just before the morning watch, he led his front maniples forward along the borders of the lake into the valley with a view of engaging the enemy.
