The Battle of the Metaurus was a pivotal battle in the Second Punic War between Rome and Carthage, fought in 207 BC near the Metaurus River in present-day Italy.

The Carthaginians were led by Hannibal's brother Hasdrubal Barca, who was supposed to bring the siege equipment and reinforcements needed in order for Hannibal to defeat Rome. The Roman armies were led by the consuls Marcus Livius, who would later be nicknamed the Salinator, and Gaius Claudius Nero.

Claudius Nero had just fought Hannibal in Grumentum, some hundreds kilometers south of the Metaurus river, and reached Marcus Livius with a forced march which went unnoticed by both Hannibal and Hasdrubal, so that the Carthaginians suddenly found themselves outnumbered.

[edit] Prelude

Hasdrubal's campaign to come to his brother's aid in Italy had gone remarkably well so far. After completely outmaneuvering Publius Scipio in Hispania and making his way into Gaul in the winter of 208, Hasdrubal had waited until the spring of 207 to make his way through the Alps and into Northern Italy. Hasdrubal made much faster progress than his brother had, partly due to the constructions left behind by Hannibal's army when he had passed via the same route a decade earlier, but also due to the removal of the Gallic threat that had plagued Hannibal during said expeditions. The Gauls now feared and respected the Carthaginians, and not only was Hasdrubal allowed to pass through the Alps unmolested, his ranks were bolstered by many enthusiastic Gauls. Hasdrubal, in the same fashion as his brother, succeeded in bringing his war elephants, raised and trained in Hispania, over the Alps.

Rome was still reeling from the devastating blows which Hannibal had landed on it in rapid succession ten years earlier, and the prospect of fighting two sons of "the Thunderbolt" (a rough translation of Hamilcar Barca's surname) at once terrified the Romans. The hastily elected consuls Claudius Nero and Marcus Livius were dispatched to face Hannibal and Hasdrubal respectively. Neither consul engaged his intended target initially. Claudius Nero's force of over 40,000 men was too formidable for Hannibal to engage openly, and so the two played an unproductive game of cat and mouse in Bruttium; meanwhile, Marcus Livius, despite the added bulwark of two of the many Roman armies scattered across Italy - yielded cautiously to Hasdrubal, allowed him to push beyond the Metaurus as far south as the town of Sena.

It was not until Hasdrubal sent messengers to Hannibal that decisive measures were taken. Hasdrubal wished to meet with his brother in South Umbria. However, this was not to be. Hasdrubal's messengers were captured, and his plans laid in the hands of the consul Claudius Nero, who quickly departed to the North with 7,000 men, 1,000 of whom were cavalry, in order to meet with Marcus Livius. Claudius Nero, recognizing the urgency of the situation and the enormous threat that a merging of the Carthaginian brothers' armies would present to Rome, circumvented the authority of the Senate, instead advising them to organize levies for their own protection.

[edit] Union of the Two Consuls

Claudius Nero quickly reached Marcus Livius, who was camped at Sena along with the praetor Porcius. Hasdrubal was camped approximately a half-mile to the north. However, since Claudius Nero had conveniently arrived at night, his presence was not detected until the next day, when the Romans drew themselves up for battle. Hasdrubal drew his army up as well, but upon closer observation of the forces assembled before him, noticed that Marcus Livius' army seemed to have grown considerably over the course of the night, and that he had a much larger contingent of cavalry. Hasdrubal remembered hearing a trumpet in the Roman camp heralding the arrival of an important figure the night before - a sound he had become familiar with during his entanglements with the Romans in Hispania - and now correctly concluded that he was in fact facing both Roman consuls. Unnerved, he retired his troops from the field.

The rest of the day passed without event, for the Romans did not endeavour to advance on Hasdrubal's fortifications. When nightfall came, Hasdrubal quietly led his army out of his camp with the intent of retreating into Gaul, where he could safely establish communications with Hannibal. Early on in the march, however, Hasdrubal's guides betrayed him, and left him lost and confused along the banks of the Metaurus, searching futilely for a place to cross.

The night passed with no change in Hasdrubal's forces, and the morning found his army uncertain and confused, and a great many of his Gallic troops drunk. With the Roman cavalry fast approaching and the legions under the two consuls not far behind, Hasdrubal reluctantly prepared for battle.

[edit] The Battle

The exact numbers of troops on both sides are not known. The data given by the ancient sources are either insufficient or very contradictory. Appian for instance says that the Carthaginian force numbered 48,000 infantry, 8,000 cavalry and 15 elephants^[2]. Livy claims that there were more than 61,000 slain or captured Carthaginian soldiers at the end of the battle and there were still more who escaped the slaughter^[3]. These figures look inflated, especially when one compares them with the account left by Polybius. Some estimates suggest Hasdrubal's army was about 30,000 in strength^[4], and Marcus Livius' initial army equal that^[5], plus the 7,000 troops who had accompanied Claudius Nero. It is certain that Hasdrubal was indeed outnumbered, and that he was also very much lacking cavalry, of which the Romans had ample numbers. Nonetheless, he arranged his troops in the most practical manner available to him.

Like most Carthaginian armies, Hasdrubal's was a mix of many different cultures and ethnicities, few of which were of African origins. Hasdrubal's best troops were Iberians, armed with shields and swords, and these troops he placed on his right flank along with the few African troops that he did have (not much is known about these troops - they may have been spearmen drawn from some Carthaginian territory, or from another part of Africa). In his center he drew up a formidable force of Ligures who were not as well-trained as the men on his right flank. Finally, on his left, he placed the disorderly Gauls, who he hoped would be shielded by the intraversable terrain (a deep ravine) in front of them. Hasdrubal also had ten elephants in his army.

The Romans advanced on Hasdrubal in a very orderly fashion. Claudius Nero was given command of the Roman right flank, facing the inaccessible Gauls. It was Marcus Livius who initiated battle, charging the veteran Iberian infantry, and Porcius followed soon after by attacking Hasdrubal's Ligurians. The initial combat was favorable to Hasdrubal, whose elephants succeeded in breaking the Roman line and spreading mass confusion throughout Marcus Livius' troops. Hasdrubal's right wing held firmly, and his Ligurians, too, held their ground. Claudius Nero struggled to overcome the terrain that blocked his path to the unprepared Gauls on Hasdrubal's left, and, seeing the futility in wasting further time attempting to reach them, instead took some of his men and led them away from the Gauls, behind Marcus Livius and Porcius, who were preoccupied with battle, and marched to the extreme Roman left, swinging his troops around and crashing into the Iberians' flank with such sudden force and intensity that the Iberians panicked and fled in confusion, collapsing onto the Ligurians, who continued to fight until they were cut down.

Hasdrubal's only remaining forces, the Gauls, who were still totally unfit for combat following their activities the night before, were no longer protected by their sober comrades who had been guarding their flank. The Romans descended mercilessly upon them, meeting almost no resistance.

The Carthaginian general, seeing that there was nothing more he could do, and presumably doubtful of his own prospects of escape, or simply unwilling to be taken captive, charged into the thick of the nearly concluded battle and met a glorious, if pointless death. Depending on whether one believes Polybius or Livy 10,000^[6] or 56,000^[7] of Hasdrubal's soldiers perished with him. According to the same authorities the casualty figure among the Romans was between 2,000 and 8,000.

[edit] Aftermath

Claudius Nero showed neither respect nor compassion for his fallen adversary following the battle of the Metaurus. He ordered Hasdrubal's head severed from his body, and had it thrown into Hannibal's camp as a sign of the brother's defeat.

Lord Byron wrote of the battle:

"The consul Claudius Nero, who made the unequalled march which deceived Hannibal and deceived Hasdrubal, thereby accomplishing an achievement almost unrivaled in military annals. The first intelligence of his return, to Hannibal, was the sight of Hasdrubal's head thrown into his camp. When Hannibal saw this, he exclaimed, with a sigh, that 'Rome would now be the mistress of the world.' To this victory of Claudius Nero's it might be owing that his imperial namesake reigned at all. But the infamy of the one has eclipsed the glory of the other. When the name of Claudius Nero is heard, who thinks of the consul? But such are human things."

Though history may not remember Nero the Consul, the effects of the battle he won and the Empire which it safeguarded are certainly well-known. With his brother dead and his soldiers routed or killed, and no hope of help from Carthage - which was too concerned with its own political battles to send him aid - Hannibal's hopes of mustering a force sufficient in size and strength for the achievement of his war aims were utterly dashed. He remained in Italy for several years, unmolested by Rome, and attempted to maintain the loyalty of the Italian allies whom he had won early on in his campaign. It was not until Scipio Africanus led a campaign directly against Carthage that Hannibal left Italy. The two generals faced one another at the Battle of Zama in 202 BC, where Hannibal, like his brother, faced a superior force, offered a good fight, and was ultimately defeated.

Had Hasdrubal succeeded in linking up with his brother, the outcome of the Second Punic War might have been very different. The addition of Hasdrubal's men to his ranks would have swelled Hannibal's army to a number great enough to lead a direct advance on Rome itself, and in the event of such a siege, it is quite possible that Hannibal's forces would have succeeded in taking the city. Even if Rome did not fall to Hannibal, the presence of the brothers' combined armies in Italy would only add to the political strife that already existed there, not to mention the anxiety that lingered throughout Rome. History is too unpredictable to say what might have happened had the Battle of the Metaurus not occurred; however, the fact that it did was clearly in the best interests of Rome.

The significance of the Battle of the Metaurus is recognized amongst historians. It is included in Edward Creasy's The Fifteen Decisive Battles of the World (1851), the rationale being that it effectively removed the Carthaginian threat from Rome's ascendancy to global dominion by leaving Hannibal stranded in Italy. Like the Battle of Tours, however, the significance of the Battle of the Metaurus is greatly understated in most circles. It is very much overshadowed by other battles of the Second Punic War, such as Hannibal's awesome victory at the Battle of Cannae or his ultimate defeat at the Battle of Zama. Nonetheless, the effects of Claudius Nero and Marcus Livius' victory at the Metaurus have earned it a significant standing amongst historians, not only in the history of Rome, but in that of the entire world.

^ According to Livy, 27.36, the propraetor L. Porcius Licinius had two legions, as much as the consul. This means that Livius and Porcius had four legions equal to 32,000-40,000 men together with the Allies. However the number of the Allied contingents could have been less than usual due to the refusal by some of the Latin colonies to provide auxiliaries. The Roman force was probably further diminished by preceding fighting with Hasdrubal the evidence of which is the presence of several thousand prisoners in Hasdrubal's camp.
