Warfare, particularly raiding, was endemic throughout the Spanish Peninsula. Like the tribes of Gaul, the peoples of Spain habitually raided their neighbours, and it was a dispute of this sort which had provided the ostensible reason for Hannibal's attack on Saguntum. Tribes or towns perceived to be weak were mercilessly raided, every successful attack encouraging similar enterprises. A leader could only expect to command the loyalty of allied communities for as long as he was able to protect them from depredations. A reputation for military might, achieved primarily by aggressive campaigns against others combined with swift reprisals to avenge any attack, deterred raiding, but this was hard to maintain and even a small defeat encouraged more raids. Both Rome and Carthage relied overwhelmingly on Spanish soldiers, who formed the most numerous element in almost every army in the Peninsula. Some of these troops were mercenaries, but the bulk were allies, whose loyalty was based above all else on a belief that whichever side they had joined was the stronger, at least locally. Defections followed rapidly when either Rome or Carthage came to be seen as weak. The old Carthaginian province covered only a small area, with its heartland around New Carthage and Gades. Elsewhere, although rapid campaigns had overrun other tribes, the Punic position had not yet been consolidated.

In 218, having failed to intercept Hannibal on the Rhone, the consul Publius Scipio had sent his brother Cnaeus with the bulk of his army on to his province of Spain, before returning himself to confront the enemy in Cisalpine Gaul. Cnaeus had two legions and a strong allied contingent, an impressive army of perhaps 20,000-25,000 men. Sailing along the coast, he landed at the Greek colony of Emporion, a city with which Rome already had some sort of relationship, either directiy or through her ally Massilia. Other communities in the area proved ready to ally with Rome. Hannibal had swept through the area north of the Ebro in a few months, leaving Hanno with 10,000 foot and 1,000 horse to control it. Soon after disembarking his army, Cnaeus advanced against this force and easily defeated it at a place called Cissa, probably somewhere near Tarraco (modern Tarragona). Hanno was captured along with the heavy baggage which Hannibal had left under his protection before setting out for Italy. Also captured was a chieftain of the Ilergetes, a man named Indibilis (Andobales in Polybius) who appears to have been one of those strong leaders able to dominate communities from other tribes as well as his own. The Romans spread out and soon most of the tribes and cities north of the Ebro were defeated or voluntarily defected. Hasdrubal Barca, left in overall charge of Spain by his brother, hastily put together an expeditionary force when he heard of Scipio's arrival and, according to Polybius at least, of Hanno's defeat. With 8,000 foot and 1,000 horse he crossed the Ebro and attacked elements of the Roman fleet which had scattered around the coastal areas to raid the local communities. Dispersed and careless, several groups of Roman marauders were caught by the Cartaginians and cut to pieces. The survivors fled and several officers were punished by Cnaeus for their unnecessary defeat. Hasdrubal withdrew after this minor success, having neither the troops nor, probably, the supplies, to risk a longer campaign or an encounter with the main Roman force.

The Romans had established themselves in Spain, gaining allies amongst not just the Greek cities on the coast, but the native tribes of the interior. Cnaeus detached some troops as garrisons to defend both the captured cities and his new allies, before returning to winter with the bulk of his army at Tarraco. Distributions of booty, especially the prizes from Hannibal's baggage train, added to the soldiers' good spirits. In the spring of 217 Hasdrubal mustered larger forces to mount an offensive against the Roman enclave. Crews were found for a few more of the ships left to him by Hannibal, so that forty galleys, the majority 'fives', sailed from New Carthage under the command of Hamilcar. These cruised along the coast, keeping pace with Hasdrubal's army on land, under whose protection the ships could beach and the crews rest each night. We do not know the size of the Punic army, but we must assume that it was substantial since Cnaeus decided that it was unwise to follow his first instinct and face it in battle. Instead the Romans loaded thirty-five ships with marines picked from the legions. At least some of this squadron was provided by Massilia, a maritime city whose sailors had a high reputation. Moving south along the coast, Cnaeus paused about 10 miles from the enemy and sent two small Massiliote ships forward to scout. When these reported that the Punic fleet was beached near the mouth of the Ebro, Cnaeus decided to launch an immediate attack in the hope of catching the enemy unprepared. However, Carthaginian scouts along the coast had already spotted the enemy fleet and warned Hasdrubal, who rapidly ordered Hamilcar to embark and put to sea. The rival squadrons engaged willingly, but the fighting did not last long and ended in a clear Roman victory, perhaps due mainly to the actions of the Massiliotes. Polybius argued that the presence of the Punic army did less to encourage their sailors than to offer them an easy prospect of flight to safety. Perhaps more importantly, at least a quarter of the Punic crews were recently raised, and even the existing ships' companies may not have been especially well-trained. Marauding expeditions rather than naval fighting were a far more common activity for the Punic fleet in Spain. Two Carthaginian ships were lost, four more lost their oars and marines, whilst the rest fled to the sanctuary of the army, beaching themselves in panic. Twenty-five enemy vessels were captured by the Romans, who had arrogantly rowed inshore and towed away many of the beached ships. The Roman fleet may have mounted a few raids along the Punic-held coastline later in this year, but the details are obscure. More Iberian communities sought alliance with Rome after this display of strength. Livy's narrative of this period is not supported by any of the extant passages of Polybius, but he claims that tribesmen from the Ilergetes raided communities friendly to Rome and were in turn attacked by Cnaeus, whilst the Romans managed to persuade some Celtiberians to ravage Carthaginian territory.

Encouraged by Cnaeus' successes, and in particular his naval victory, the Senate decided to send reinforcements to Spain under the command of his brother, Publius, now recovered from the wound suffered at Ticinus. In late 217 Publius arrived with twenty or thirty warships and a draft of 8,000 men along with food and supplies. The brothers, both given proconsular
imperium
,
were ordered to take the offensive and under all circumstances to prevent troops, supplies or money being sent from Spain to support Hannibal. With their combined forces, Cnaeus and Publius pushed across the Ebro and advanced towards Saguntum, where the treachery of a Spanish leader brought them an unexpected reward. This man, Abilyx, outwitted the local Punic commander into freeing a group of hostages, mostly the sons of aristocrats taken from the tribes by Hannibal, and handed them over to the Romans. Abilyx's action was prompted by his belief that the Romans were now stronger and more likely to prevail than the Carthaginians, to whom he had been conspicuously loyal in the past. Returning these to their home communities, the Romans were able to persuade more of the tribes to join them, Abilyx pleading their cause with great enthusiasm.

Hasdrubal was in the meantime occupied with suppressing the rebellion of a tribe that Livy calls the Tartesii, incited in part by men, presumably tribesmen, who had deserted from the Punic fleet. In 216 he received from Carthage a small reinforcement of soldiers and orders to mount an expedition to join his brother in Italy. Hasdrubal replied that he lacked the resources to undertake this and still protect the Punic province in Spain and only after receiving more troops under Himilco did he begin serious preparations for a move to Italy. As Hasdrubal began to move out, either in late 216 or more probably at the very beginning of the campaigning season in 215, the Romans concentrated their forces and confronted him near the town of Ibera, just to the south of the Ebro. For several days the rival armies camped about 5 miles apart, but neither side felt ready to offer battle. Then, apparently on the same day, both armies deployed in battle order and advanced to contact. The Romans deployed in the usual
triplex acies
with cavalry on the wings. Hasdrubal placed his Spanish allied foot in the centre of his line, flanked by Libyan and mercenary infantry on the left and Carthaginians on the right. It is distinctly possible that this last contingent consisted of troops from the Punic colonies in Spain rather than Carthage itself. The cavalry were divided between the wings, the right being held by a contingent of Numidians. The cavalry, or perhaps the flanks of the infantry line were strengthened by a force of elephants, perhaps the twenty-one left by Hannibal in 218. Numbers were roughly equal on the two sides, but our sources supply no figures for either army. Hasdrubal's deployment has frequently been compared to his brother's formation at Cannae, and the assumption made that he wanted the Romans to push back his centre and so make it easier to envelop them. This is certainly an error. The tactics of Cannae were peculiar to the local situation. Perhaps there is some similarity to Trebia, when Hannibal put his best infantry on the flanks to support the anticipated success of his cavalry wings. Livy tells us that Hasdrubal's centre of Spanish troops was solid, not deliberately thinned as Hannibal's was at Cannae. Even so, these warriors gave way quickly, which probably explains the mistaken comparison with Hannibal's victory in 216, although his centre held out for some time. Livy claimed that the Spanish were unenthusiastic about marching away from their homeland and gives this as the reason for their flight, which occurred after only a brief exchange of missiles before the two sides had closed to hand-to-hand contact. The Roman legions then did what the manipular system was designed to do, the reserve lines exploiting the breakthrough and wheeling to right and left to roll up the flanks of the enemy line. The Libyans and Punic troops put up a much harder fight against the flanks of the Roman line, but without reserves of his own there was nothing that Hasdrubal could do to plug the gaping hole in his centre. There was apparently little serious fighting between the cavalry and the Carthaginian horse fled after seeing the destruction of their own infantry. Cnaeus and Publius completed their victory by storming the enemy camp and plundering it. The threat of a second invasion of Italy was ended for the foreseeable future and this triumph persuaded even more tribes to abandon Carthage and side with the Romans.

Livy's narrative for the next few years of the war in Spain presents many problems. The defeat at Ibera prompted the Carthaginians to send more troops to Spain, notably the forces under Mago Barca originally intended to go to Italy. In the years after Cannae there was far less prospect of reinforcement for Cnaeus and Publius Scipio, who on at least one occasion complained to the Senate of their lack of resources, a problem exacerbated by the corruption of some of the companies contracted to supply the legions in Spain (already mentioned in the last chapter). However, although numbers had started to favour the Carthaginians, the Romans were not their only enemy. Controlling a much larger area of the Peninsula required the dispersion of their forces to protect their allies from attacks and suppress rebellions by tribes bribed by the Romans or encouraged by their successes. Three main armies were formed, but each commander tended to concentrate on the problems of the area under his immediate control. This, perhaps coupled with personal disagreements, frequently prevented the effective co-ordination of and mutual support between the Punic forces. Their problems were not solely confined to Spain. Appian claims that Hasdrubal and a large force had at some point to return to Africa to suppress a rising by the Numidian King Syphax. Livy also tells us that Cnaeus and Publius negotiated with this monarch, as Scipio Africanus was later to do, and even sent him centurions to train his army in Roman drill and discipline. More often they devoted their efforts to raising rebellion amongst the Carthaginians' Spanish allies. The years after 215 were ones of steady progress in Spain for the Romans, although their sphere of influence was still predominantly in the north. Raids were sent further into Punic-held territory, minor encounters won and towns captured.

In 211, or, according to Livy but less probably, 212, the Roman commanders in Spain decided to launch a major offensive. Two of the Punic armies led by Mago Barca and Hasdrubal Gisgo had for once united and were a mere five days' march away, whilst Hasdrubal Barca was slightly closer to the Romans near a town called Amtorgis. The Romans had added 20,000 Celtiberian allies or mercenaries to their army and felt themselves strong enough to confront both enemies simultaneously. Together the brothers advanced as far as Amtorgis, but then Publius led out two thirds of the old army, the legions and Italian allies, to face Mago and Hasdrubal, whilst Cnaeus with the remaining third and the Celtiberians confronted Hasdrubal Barca. The latter made use of the usual days of waiting before a battle to hold secret negotiations with the Celtiberian chieftains, who were bribed to return home. The tribesmen considered this breach of faith entirely honourable, since they were not actually being asked to fight against their allies. To the dismay of Scipio and his soldiers, the Celtiberians simply marched away. This was not the only occasion when these warriors, who had a great reputation for ferocity when they did choose to fight, behaved in such a manner. Now greatly outnumbered by Hasdrubal, Cnaeus had little choice but to retire in haste.

By this time Publius Scipio had already suffered disaster. As the Romans drew near to the adjacent camps of Mago and Gisgo, their column was severely harassed by Numidian light horsemen, inspired by the leadership of a young prince named Masinissa, who was later to play a major role in events. The Roman outposts and foragers suffered severely and the repeated attacks made the soldiers nervous. Scipio discovered that the Carthaginians were soon to be joined by the chieftain Indibilis and 7,500 tribesmen from the Suessetani and decided to intercept the approaching force and destroy it. Leaving a small garrison in camp, he led his troops out in a night march, a typically bold action. The resultant encounter was confused, neither side managing to form a proper battle line. Things rapidly started to go wrong for the Romans. Masinissa and his Numidians found them and attacked suddenly from one flank. Later the main Punic army arrived and the pressure became overwhelming. Publius Scipio, riding round the front lines as a Roman general should to inspire and organize the men, was killed by a thrown javelin. As the news of his death spread, the Roman army dissolved into rout, to be massacred as they fled by the eagerly pursuing Numidians and Punic light infantry.
