Even his enemies acknowledged his military genius, though they were inclined to accuse him of Punic perfidiousness, perhaps because he had so often outwitted them. They also believed him to be cruel, although a similar charge could be laid against most of the 'Great Captains' of antiquity and Polybius suggested that some of the more brutal acts attributed to him may in fact have been committed by one of his subordinates, another Hannibal, nicknamed Monomachus, which means 'fighter of single combats' or 'duellist'. This man is supposed to have shocked a meeting of senior officers called by Hannibal to plan the invasion of Italy by suggesting that they solve their supply problems by training the soldiers to eat human flesh. Polybius also believed that men may be forced to commit acts of great cruelty in spite of an otherwise good nature, if a difficult military or political situation made such actions necessary. Polybius seemed to accept the charge repeated by most of our sources that Hannibal was overly avaricious. However, the sources he gives for this, namely a conversation with King Masinissa, the Numidian leader who defected to the Romans later in the war and had little love for his former Punic masters, and the opinion of Hannibal's political rivals who forced him into exile from Carthage in the years after the war, do not inspire confidence. Hannibal's apparent thirst for money may well have been necessary throughout the Italian campaign to support his army and pay his soldiers.

The true character of Hannibal eludes us. None of our sources provide the equivalent of the anecdotes told about the childhood and family life of the important Greek and Roman politicians of the era, many of whom were the subject of detailed biographies. We can say a good deal about what
Hannibal did during his career, and often understand how he did it, but we can say virtually nothing with any certainty about what sort of man he was. As with so much else about Carthage and its leaders, there are so many things that we simply do not know, that even our sources probably did not understand. Was Hannibal for instance a Hellenized aristocrat who dreamed of copying and surpassing the great expeditions of Alexander or Pyrrhus, or did he remain very much the Punic nobleman with a very different set of beliefs and ambitions? Much as we try to understand Hannibal, he will always remain an enigma.
The March to Italy
The actual route Hannibal's army followed on its march to Italy has long fascinated historians. Even in Livy's day, there was a fierce dispute over which pass the Carthaginians had taken over the Alps. For many people, tracing the route has become a passion, and academics and ex-soldiers, including no less a figure than Napoleon, who himself campaigned in the area, have indulged in endless speculation, often spending many days travelling over the land itself. Their conclusions have varied enormously and unfortunately the nature of our sources makes it impossible to resolve these disputes. I do not intend to discuss this topic since it would be impossible to do it justice in the framework of a treatment of all three Punic Wars, in addition to which I do not possess the intimate knowledge of the ground of the best contributors in this field. In this section we shall simply trace the major events of Hannibal's march, mentioning only in passing the most favoured theories concerning the location of these episodes.
26
Hannibal set out from New Carthage in late spring 218 and moved towards the River Ebro, a distance of about 325 miles (2,600 stades). His huge army probably advanced in several smaller groupings to relieve congestion on the main routes and ease the supply situation, for they crossed the river in three separate columns at different places. Although the Ebro treaty had earlier been of great significance, war between Rome and Carthage was already certain by this point, and the crossing merely confirmed this. Hannibal led his troops in a series of lightning expeditions against the tribes between the Ebro and the Pyrenees. Speed was essential if he was to reach Italy before the end of the year, so Hannibal drove his soldiers hard and was willing to accept a high casualty rate, taking fortified towns by direct assault and fighting a number of actions. After perhaps a month of intense fighting, at least four tribes had been overawed by this display of Punic military might and the violence of the onslaught. Yet the area was certainly not conquered and, like many other parts of Spain subdued by the Barcids, would remain peaceful only so long as the Carthaginians were perceived to be strong. To control the region Hannibal left an officer named Hanno, giving him a force of 1,000 cavalry and 10,000 infantry.
27
Although it has sometimes been suggested that Hannibal originally planned to remain west of the mountains to await the anticipated Roman invasion of Spain and only pushed on towards Italy when the Romans were delayed by the Gallic rebellion, this is not supported by our sources.
28
Instead he made a few quick alterations to his force and pushed on through the Pyrenees. All his heavy baggage was to be left behind with Hanno to allow the unencumbered army to move faster. It was now late summer and the harvest was due or already gathered in the lands the army was to pass through, allowing Hannibal to reduce the amount of food and forage carried in his pack train and instead live off the land. The great size of the army had been useful in the rapid campaign beyond the Ebro, but such numbers would prove hard to feed and difficult to control on the longer march to Italy, so Hannibal planned to take only the best soldiers. About 10,000 Spanish warriors were released from service and sent back to their homes. Some of these, and perhaps many others, had deserted of their own accord; one contingent of 3,000 Carpetani are mentioned as doing so during the crossing of the Pyrenees. By the time Hannibal crossed into Gaul he had an army of9,000 cavalry and around 50,000 infantrymen, still large by the standards of the day, but more manageable and highly experienced. Even with the other detachments mentioned by our sources, the army's numbers had shrunk by some 20,000 men. Some of these were doubtless casualties in the operations beyond the Ebro, but the majority were probably stragglers and deserters. If, as seems likely, much of the army consisted of recently raised and inexperienced troops, many of these may well have lacked both the enthusiasm and the stamina to undertake the long marches Hannibal expected from his soldiers.
29
After the Pyrenees, which were crossed without major difficulties, the next important obstacle was the River Rhone. Earlier diplomatic activity and the reception of chieftains with lavish gifts had proved highly successful and it was not until the river that Hannibal faced his first military opposition from the Gallic tribes. Polybius tells us that he reached the river at a point about four days' march from the sea, but the precise location is disputed. The people to the west of the river were generally friendly, especially when the Carthaginians began to pay them for the use of their boats and other material needed for the crossing, but on the far bank a sizeable tribal army had mustered to contest his crossing. Livy says that the tribe was the Volcae, the same people who lived on both sides of the river, but that most had fled to the far bank as the Carthaginians approached. The river was a formidable obstacle, and Hannibal was reluctant to force a crossing in the face of such strong opposition, so camped beside it and waited whilst his men constructed rafts. The Gauls may well have hoped that a display of force and the width of the river might have deterred the invader from attacking at all, for it seems to have been common amongst many tribes to use physical boundaries to mark the point at which they would defend their territory. In tribal warfare a show of determination may often have been enough to persuade an enemy to withdraw.
30
Three nights after his arrival, Hannibal sent a detachment of men under cover of darkness to seek a crossing point upstream, giving the command to another Hanno, this one known as 'the son of Bomilcar the Suffete'. Led by local guides this party, which consisted mainly of Spaniards, marched about 25 miles to reach a point where the river forked and formed an island. Building rafts, and with some of the Spaniards swimming with the aid of inflated animal skins, they crossed and camped; Hanno then allowed his weary men a day's rest. The next night, the second after they left the main army, this detachment pushed south, arriving near the Gallic army by dawn. Using a prearranged signal, they lit a beacon to inform Hannibal of their presence. At once he ordered his army to cross the river, some of the horses being towed behind rafts or boats. The Gauls mustered to oppose them, but began to panic when Hanno's troops made a sudden attack on their camp, setting it on fire. Hannibal seems to have crossed amongst the leading troops, for he swiftly began forming up his army on the east bank and advanced to meet the reeling enemy. The Gauls never recovered from their surprise and, perhaps dismayed to see the enemy making light of the supposedly strong obstacle, soon broke into flight.
31
After this victory, Hannibal's main concern was to bring the remainder of his army across the river, using the craft he had purchased or constructed on the spot. Men were detailed to prepare for the major task of carrying the elephants across the river. There are several different versions of how this was achieved, but the earliest and most likely is that engineers constructed several rafts, 50 feet (15 m) in width, two of which were fastened to the western bank of the Rhone. Additional rafts were lashed into place at the end of these, creating a bridge 200 feet (61 m) in length. At the end of this roadway were two smaller rafts which could be cut free and towed across the river by small boats to ferry the animals across. To persuade the nervous animals to step onto the raft in the first place, earth was spread over the planking to make it appear like dry land, and two cow elephants driven on first to persuade the majority of male animals to follow. When the ferry was cut loose from the bridge many of the elephants panicked at the unfamiliar motion of the water and, despite the attempts of their mahouts to calm them, a few jumped into the river. Several mahouts were drowned, although all the elephants were able to make their way across.
32
Hannibal used the delays imposed by ferrying men and animal across the Rhone to rest his army. He held parades where he brought before them representatives from Cisalpine Gaul, notably the chieftain Magilus, who encouraged the men with promises of the aid they would receive and the plunder to be gained once the army reached Italy. It was during this halt that the news arrived that a Roman fleet had anchored off the mouth of the Rhone near Massilia. Hannibal immediately despatched 500 Numidian light horsemen to reconnoitre the enemy presence and report on their activity.
33
The Roman fleet carried the army of Publius Scipio, who, after a long delay, had at last begun his move to confront Hannibal in Spain. The Romans had left Pisa and sailed along the coast of Liguria, reaching Massilia in five days, although it is probable that at least one, and probably several, landfalls were made before this to rest the crews. Apart from the limited range of ancient fleets, it made considerable sense for the Romans to confer with the Massiliotes before proceeding on to Spain, since this Greek city and faithful ally had a far greater knowledge of the area. It is most probable that it was only after arriving at Massilia that Scipio learned of Hannibal's crossing of the Pyrenees, since only reports of his march across the Ebro seem so far to have reached Italy. The news caused an immediate change of plan. Scipio's main objective was to confront the Carthaginian general who had initiated the war and there was no point in continuing to Spain when Hannibal was in southern Gaul. The Roman troops disembarked from their transports and spent several days recuperating from their sea voyage, preparing for the anticipated battle with the enemy. It is unclear how much of Scipio's army was present, but their commander's willingness to offer battle suggests that he had the vast bulk of the consular army allocated to him. Scipio still believed that Hannibal was many days' march away, but was swiftly disabused of this idea when a report arrived that the Carthaginians had reached the Rhone. Amazed at the speed of the enemy advance, the Roman general organized a reconnaisance, sending his 300 best horsemen, led by local guides and supported by a force of Gallic mercenary cavalry provided by the Massiliotes.
34
The rival scouting parties bumped into each other and fought a short and bloody skirmish. Our sources claim that 200 out of 300 Numidians were killed, whilst the Romans and their allies lost 140 men. If these figures are correct then they would represent exceptionally high losses in proportion to the forces involved, but it may well be that both sides made exaggerated claims for the casualties they had inflicted on the enemy. The Roman force chased the Numidians back to Hannibal's camp and certainly believed that they had won a great victory, although it is possible that the enemy light horsemen withdrew deliberately because they were there to look and not to fight. The Romans then hurried back to Scipio to inform him that they had located Hannibal and his army. The consul did not hesitate, but loaded all his heavy baggage back onto his ships and led his army as fast as possible towards the enemy with the intention of bringing him to battle. They were too late. By the time the Romans reached Hannibal's camp, they discovered that the Carthaginian army had marched on up the Rhone three days before. Scipio was in no position to follow them. His heavy baggage had been left behind and he had not had sufficient time to arrange with the Massiliotes to gather enough food to supply his army, or the pack and draught animals needed to transport it overland. At best his soldiers had food for a few more days. Foraging for provisions would have been difficult in autumn and would anyway have slowed the Romans down, making it even less likely that they would be able to intercept the enemy. Even if he had possessed better logistic support, following the enemy would have taken the Romans into unfamiliar land, peopled by probably hostile tribes, and there was no assurance that he could catch up with the enemy.
