Eventually, in mid-December 218, Sempronius Longus arrived with fresh troops. Conscious that his term of office was drawing to a close, and with it the chance of a glorious triumph, Longus was impatient to engage the Carthaginian army in open battle, especially as his own troops appeared to have come off best in a number of minor skirmishes. In fact Hannibal had merely withdrawn his troops to near the Trebia, preferring to conserve his military strength for an encounter of his own choosing. The strategy had worked, because Longus, buoyed by these meaningless victories, was ready to commit his forces to a major confrontation. Scipio attempted to get his consular colleague to reconsider, arguing that their raw troops needed more training over the winter months, and that a period of inactivity would ensure that the notoriously fickle Gauls would start to question their new-found allegiance to Hannibal. Longus, however, was not to be deterred, and Hannibal did everything in his power to encourage a Roman attack.
After boosting Longus’ self-confidence, Hannibal now set the trap. Selecting an area between the two camps where plants and undergrowth covered the steep sides of a riverbank, he organized an ambush party of 1,000 horse and an equal number of foot under the command of his brother Mago. The next day at dawn he sent his Numidian cavalry across the Trebia, where they proceeded to provoke the Romans by hurling javelins and abuse at their camp. Predictably, Longus ordered his troops to pursue them. Although the whole Roman force forded the river and drew up into their battle lines in good order, the troops were cold, wet and hungry after being mobilized before they had breakfasted. In contrast, the Carthaginian troops had been well prepared and fed. Both sides appear to have had around 40,000 men each, and, although the heavily armed foot soldiers in the centre were evenly matched, once again Hannibal’s superior and more numerous cavalry easily bested their Roman counterparts, leaving the flanks of the Roman infantry exposed to attack. It was then that Mago’s small force launched its ambush on the rear of the Roman infantry. Around 10,000 Roman soldiers managed to fight their way out and make it to the nearby town of Placentia, but many others were killed.
38
Longus escaped and subsequently tried to convince his fellow citizens that the defeat had occurred only because of the extreme weather conditions. However, few if any appear to have believed him.
39
Meanwhile, it took Hannibal little time to persuade the Italian cities to desert the Romans. The Roman and Italian prisoners of war were treated in quite different ways: the former were put on starvation rations; the latter were treated well and eventually sent home. Before they left, Hannibal addressed them and said that ‘he had not come to make war on them, but on the Romans for their sakes; and therefore if they were wise they should embrace his friendship, for he had come first of all to re-establish the liberty of the peoples of Italy and also to help them to recover the cities and territories of which the Romans had deprived them.’
40
The harsh winter of 218/217 granted the Romans some respite, for Hannibal lost a large number of men and horses to the bitter cold, as well as all but one of his elephants.
41
After wintering in Bologna, the Carthaginians moved south and crossed the Apennines into Etruria. They suffered terribly as they spent four days and three nights tramping through terrain so marshy that it was impossible to set up camp. Hannibal, who rode on top of the one remaining elephant, was afflicted by opthalmia, which led eventually to blindness in one eye.
42
In recognition of the threat that they now faced, the Romans had mobilized over 100,000 fighting men. Concerned that the Carthaginians might launch attacks on Rome’s new central-Mediterranean empire, it was decided to send two legions to defend Sicily and another to Sardinia. Two further legions were charged with the defence of Rome itself. The four legions, now under the split command of the two new consuls, Gaius Flaminius Nepos and Gnaeus Servilius Geminus, were reinforced to make up their losses to Hannibal in the previous year.
Flaminius was an impetuous and arrogant man, whom Hannibal immediately tried to goad into rash action by ravaging the agriculturally rich Chianti region where Flaminius and his army were stationed. He consequently managed to lure Flaminius and his army into the Borghetto pass, where on the shore of Lake Trasimene an ambush had been set. The mist of the early morning of 21 June 217 made visibility poor, and the Romans did not see the danger until it was too late. Chaos ensued, and over 15,000 Roman troops were cut down, including Flaminius himself. Some retreated into the waters of the lake, where they drowned in their heavy armour, and 6,000 troops who had survived surrendered when they realized the hopelessness of their situation.
43
In his treatment of them, Hannibal continued his policy of distinguishing between Roman and Italian prisoners, for the latter were sent home without ransom, while the former languished in captivity. The Carthaginian general also had the superior Roman heavy armour and weapons collected up and redistributed to his own Libyan infantry.
44
A few days later the other consul, Geminus, lost virtually all his cavalry as another surprise attack rendered his force virtually worthless.
45
According to Livy, the news that arrived in Rome after the Carthaginian victory told not only of military defeat, but also of strange and ominous portents in central Italy. Particularly notable are reports that blood had appeared in the sacred spring of Hercules at Caere, an apparent indication of the success with which Hannibal had associated himself with the hero.
46
The Roman reaction, which consisted in offering up prayers at the shrine, certainly suggests an attempt to win Hercules back to the Roman cause.
47
The battle for supremacy was thus being fought on both the temporal and the celestial plane.
Hannibal, recognizing the poor physical shape that his troops and animals were now in, decided to recuperate on the more clement Adriatic coast. According to Polybius, the Carthaginians had by that time captured so much booty that they had grave difficulty transporting it to their new base. After two years away from the sea, Hannibal now had the opportunity to send a message back to Carthage to inform the Council of his victories. The news was met with great celebration in North Africa, and Carthage sent back a message promising support for the campaign both in Italy and in Spain.
48
In contrast, the mood in Rome was one of panic, as news of this latest and most terrible defeat trickled in with the survivors. The populace had thronged around the Forum Romanum and the Senate House, waiting for confirmation from the magistrates. On this occasion the disaster was such that no positive spin could be put on it. One of the praetors climbed on to the speaker’s rostrum and simply said, ‘Pugna magna victi sumus’–‘We have been defeated in a great battle.’
49
With one consul dead and the other unable to return, the Romans decided to compromise Republican ideology and appoint a dictator, a temporary autocrat allowed by the constitution only in times of intense crisis. The people chose the vastly experienced Quintus Fabius Maximus, twice consul and once censor, with Marcus Minucius Felix to assist him as Master of the Horse.
50
THE RETREAT OF THE ROMAN GODS?
Fabius, learning from the mistakes of his predecessors, took a very different approach to the war against the Carthaginians. After recruiting two new legions and taking over the two which had been previously commanded by Geminus, Fabius marched to Apulia, where he resisted Hannibal’s attempts to induce him into open battle. His Greek biographer Plutarch provides a clear summary of these new tactics:
He [Fabius] did not plan to fight out the issue with him [Hannibal], but wished, having plenty of time, money and men, to wear out and gradually sap his culminating vigour, his meagre resources, and his small army. Therefore, always pitching his camp in hilly regions so as seem to be out of reach of the enemy’s cavalry, he hung threateningly over them. If they sat still, he too kept quiet; but if they moved, he would come down from the heights and show himself just far enough away to avoid being forced to fight against his will, and yet near enough to make his very delays inspire the enemy with the fear that he was going to give battle at last.
51
Hannibal, appreciating the cleverness of Fabius’ tactics, did all in his power to draw his forces out into direct combat by provocations such as the ravaging of the fertile regions of Benvento and Campania. The Romans maintained their discipline, however, shadowing the Carthaginian army and picking off raiding parties when they had the opportunity.
52
Although effective, Fabius’ tactics were very unpopular both in his own camp and on the streets of Rome.
53
Long after his death, the Romans would come to appreciate their
cunctator
(‘delayer’–as Fabius’ posthumous epithet would be), but at the time decades of successful aggressive action had enforced the popular perception that such tactics were simply un-Roman.
54
Hannibal himself further stoked up the pressure by sparing the Roman general’s own property while burning all the land around it, thus adding substance to a rumour that Fabius had been secretly negotiating with him.
55
Eventually, however, it looked as if Fabius’ unpopular strategy had paid off. In the autumn of 217 an increasingly impatient Hannibal made a terrible mistake that left his army at the mercy of the Romans.
He [Hannibal] wished to draw his army off some distance beyond Fabius, and occupy plains affording pasturage. He therefore ordered his native guides to conduct him, immediately after the evening meal, into the district of Casinum. But they did not hear the name correctly, owing to his foreign way of pronouncing it, and promptly hurried his forces to the edge of Campania, into the city and district of Casilinum, through the midst of which flows a dividing river, called Vulturnus by the Romans. The region is otherwise encompassed by mountains, but a narrow defile opens out towards the sea, in the vicinity of which it becomes marshy, from the overflow of the river, has high sand-heaps, and terminates in a beach where there is no anchorage because of the dashing waves. While Hannibal was descending into this valley, Fabius, taking advantage of his acquaintance with the ways, marched round him, and blocked up the narrow outlet with a detachment of 4,000 heavy infantry. The rest of his army he posted to advantage on the remaining heights, while with the lightest and readiest of his troops he fell upon the enemy’s rearguard, threw their whole army into confusion, and slew about 800 of them. Hannibal now perceived the mistake in his position, and its peril, and crucified the native guides who were responsible for it. He wished to make a retreat, but despaired of dislodging his enemies by direct attack from the passes of which they were masters. All his men, moreover, were disheartened and fearful, thinking that they were surrounded on all sides by difficulties from which there was no escape.
56
Hannibal may have blamed his local guides, but it was Fabius’ dogged determination that had allowed the Roman general to capitalize on this error. Hannibal, however, proved himself equal to the challenge. Learning of the Roman ambush prepared for his army, he waited until nightfall and then tied burning brands to the horns of 2,000 captured cattle. The cattle were then driven up to the high ground where the Roman troops were stationed. In the dark, the Romans, thinking that they were under attack, panicked and fled, allowing Hannibal and his army to pass through unimpeded.
57
This embarrassing incident led to further scorn and derision being heaped on the unfortunate Fabius, though the Carthaginian escape from this seemingly hopeless situation merely highlighted Hannibal’s genius rather than the shortcomings of Fabius’ tactics. In Rome, a sizeable faction had now decided that the only way of defeating Hannibal was to grant the more aggressive Minucius Felix equal powers to those of Fabius. Despite resistance from Fabius and his supporters in the Senate, the motion was passed, and the Roman forces were thus effectively split between the two commanders.
58
In the wake of his new appointment, Felix immediately attempted to establish his Herculean credentials by dedicating an altar to the hero. Within the context of the Hannibalic campaign, that dedication served to reinforce Roman claims to the Heraclean legend, but it perhaps also represented a challenge by Felix to Fabius’ own claim to direct Heraclean ancestry.
59
The battle for Heracles thus now engaged competing generals both between and within the two warring states.
Fabius, indeed, had been the first Roman general to understand the importance of countering the Carthaginian propaganda onslaught. He had Roman priests consult the Sibylline books, a collection of oracular utterances, to find out how the Romans might regain the favour of the gods, and the priests returned with three recommendations: first, the Romans should publicly renew their vows to Mars, the god of war; second, Fabius should dedicate a temple to the goddess Venus Erycina, a Sicilian goddess, and another to the divine quality of
Mens
, ‘Composure’ or ‘Resolution’; finally, the Romans should make the pledge of the ‘sacred spring’, an ancient rite whereby the entire produce of the next spring was promised to the deity of the spring if victory was achieved within a certain time.
60
The foundation of a new temple to Venus Erycina on the Capitol, completed in 215, is immediately notable for its links with the Trojan prince Aeneas, represented in Roman myth as the son of Venus, and by this period widely accepted as the forefather of Romulus and Remus. It was thought that Aeneas had married the daughter of Latinus, the eponymous king of Latium, and that upon the latter’s death he had ruled over the Latins and his own Trojan settlers. By the time of the Second Punic War, the Aeneas story had become a keystone in the ideological edifice that legitimized Roman domination of Italy, for it located the origins of that domination within a consensual agreement of the shared, mythological past.
61
The interest for the Romans in 2 17, however, was not simply in a cult of Venus, but more specifically in a cult of Venus
Erycina
. That cult was a relatively recent invention, created after the capture of Sicilian Eryx from the Carthaginians in 248.
62
Although the outer town had soon been retaken by Hamilcar Barca, Hannibal’s father, the Roman defenders had withstood several furious assaults and retained the citadel and the sanctuary within.
63
The cult was thus an important symbol of successful Roman resistance against a Carthaginian, and more specifically Barcid, enemy, and its introduction into Rome provided the city with a focal point for resistance to the new Barcid onslaught.
