Historical Setting
In 218 b.c., the Second Punic War had just gotten under way. Hannibal Barca, Carthaginian commander in Spain, had challenged Roman power in 219 b.c. by laying siege to the city of Saguntum. According to the treaty concluded at the end of the First Punic War, the city lay within a region recognized as under Carthage’s suzerainty, but the fact that Saguntum had a pro-Roman government brought a Roman declaration of war. Hannibal responded by capturing the city and then staging a brilliant forced march through the Pyrenees, southern Gaul (France), and through the Alps into northern Italy.
Hannibal’s arrival in the Po River valley forced the Roman government to cancel its original plan to land forces in Spain. Consul Publius Cornelius Scipio sailed to Massilia (Marseilles), but failed to catch Hannibal in time, so then marched down the coast into Italy to fight the invader. Meanwhile, his brother, Gnaeus Cornelius Scipio, sailed to Spain, landed in nominally Roman territory north of the Ebro River, and secured the region by defeating Hanno, one of Hannibal’s brothers. Having little luck against Hannibal in Italy, Publius Scipio was later transferred to Spain to aid his brother. They campaigned in central Spain but were defeated and killed in 211 by another of Hannibal’s brothers, Hasdrubal. The Roman Senate, desperate for a general who could score some victories, in 210 b.c. named Publius Cornelius Scipio to command in Spain. This was the son of the Publius killed the previous year. Although only 25 years old, he commanded instant respect and launched a military career that never knew defeat.
In 209, Scipio went into action north of the Ebro, securing again for Spain the land between that river and the Pyrenees. Then, in a bold move bordering on rashness, he sailed down the east coast of Spain with more than 27,000 men and attacked and captured the Carthaginian capital of Spain, New Carthage (Cartagena). This placed him in a position to threaten the lines of communication of Carthage’s army in Spain, and Hasdrubal marched to face the danger. At Baecula in 208, the two armies fought an inconclusive battle; Hasdrubal withdrew north and crossed into Italy along the same route his brother had taken 10 years earlier. Scipio did not pursue, instead searching out the remaining Carthaginian forces in Spain under Mago and Hasdrubal Gisco. He defeated them in 206 at the battle of Ilipa, where his army of 48,000 crushed an enemy force of 70,000.
Scipio was at this point master of Spain and, with Hasdrubal Barca’s defeat at the Metauraus River, Hannibal was isolated in Italy. Planning to use Spain as his base to invade North Africa, Scipio secretly traveled to Numidia (Tunisia) to deal with the two primary Numidian leaders, Syphax and Massinissa. Scipio entered into an alliance with the latter, whereas the former sided with Carthage. Scipio was invited by the Senate to return to Rome to receive his honors for his victories and to retire, but he was intent on taking the war to Carthage. Older senators and military leaders, jealous of his youth and success, instead granted him command of Sicily. Rome had dominated the bulk of the island since the end of the First Punic War, except for the kingdom of Syracuse. When Syracuse allied with Carthage in the Second Punic War in 213 b.c., the Roman general Marcellus laid siege for 2 years before finally overcoming the city’s defenses. Placing Scipio in charge was more an exile than a reward because the troops occupying the island were veterans of Roman defeats at Hannibal’s hands. Undaunted, Scipio began retraining the beaten troops while recruiting new soldiers, and in 204 he was prepared to sail for Africa whether the Senate liked it or not.
The Battle
Because Rome had command of the sea, Scipio in 204 b.c. easily was able to transport 30,000 men across the Mediterranean to North Africa and lay siege to the city of Utica (in modern Tunisia). He had to abandon the siege, however, at the approach of a Carthaginian force under Hasdrubal Gisco and the Numidian leader Syphax. Near the coast, Scipio established a fortified camp, which seemed too isolated to hold for long. Hasdrubal therefore offered Scipio peace terms, which the Roman seemed eager to negotiate. In fact, he was lulling his enemies into a false sense of security; as he was talking with them, he was planning a surprise attack on their camps. In the darkness, Scipio attacked Hasdrubal’s camp while his Numidian ally Massinissa attacked Syphax’s camp. The results were devastating for the Carthaginians. The encampments were set afire and reportedly 40,000 men were killed by the flames or while escaping them, with another 5,000 men taken prisoner. The Carthaginian commanders escaped, but left behind virtually their entire army. Scipio proceeded to reinvest Utica.
The government of Carthage was so shocked by this development that they ordered Hannibal, after 16 years of campaigning in Italy, to return home. This accomplished the first of Scipio’s goals: to take the war out of his homeland. Hannibal complied with his orders and embarked his 15,000 to 20,000 men for the voyage home on 23 June 203 b.c. With their most successful commander at hand, the Carthaginians gained heart and rejected Scipio’s rather generous peace terms. Outraged at this response, Scipio marched up the coast toward Carthage, burning every village along the way. At that, the rulers of Carthage urged Hannibal into action. He did not want to fight because his soldiers were either veterans exhausted from their long Italian campaign or raw recruits with little training or ability. Knowing also that Scipio’s force far outclassed his in cavalry, Hannibal marched out of Carthage, but contacted Scipio about negotiating. The two met at Zama, about 5 miles southwest of Carthage, and Hannibal offered Rome everything outside of Africa, but Scipio refused; after all, he reasoned, how could he trust Carthaginian promises?
Hannibal returned to his camp and prepared for battle. He deployed his men in three parallel lines: in front were the Gauls, both from southern France and from Liguria in northern Italy; in the second line he placed his weakest troops, the newly recruited Carthaginians and others from area tribes; in the rear he placed his most trusted veterans. Carthaginian cavalry was deployed on his right flank, with Numidian cavalry under Syphax on his left. Across his entire front he ranged his elephants. In total, he had approximately 45,000 infantry and 3,000 cavalry.
Scipio faced him with his 34,000 infantry in three lines as well, but out of the usual Roman formation. The Roman army was organized into maniples, or companies, numbering between 120 and 180 men. They normally deployed in a checkerboard fashion, but Scipio on this day paced them in columns. In front he placed his hastati, the youngest veterans. In the line of maniples behind them, he placed his principes, veterans about 30 years old with more combat experience. In the rear line he placed his triarii, the oldest and most steady of the veterans. In the spaces between the columns of maniples he placed his velites, the youngest soldiers armed as light infantry. Scipio ranged his maniples in columns to allow paths for the charging elephants to pass through. Like Hannibal, he flanked his army with cavalry, of which he had about 9,000: Massinissa led his Numidian cavalry on the Roman right flank opposite Hannibal’s Numidians, while Laelius commanded the Roman cavalry on the left.
Hannibal opened the battle by sending his elephants forward. Those on the left wing panicked at the sounds of Roman trumpets, however, and turned back into the Numidian cavalry, which threw a fright into their horses and disorganized them. Massinissa did not hesitate, but threw his cavalry into the melee and pursued the Numidian cavalry off the battlefield. Laelius quickly followed suit, charging into the untrained Carthaginian cavalry; they too broke, and the Roman cavalry was in hot pursuit on their end of the battlefield.
The infantry of both armies, which had stood fast during all this confusion, now began to advance toward each other. Hannibal’s superior numbers should have won in the battle, which soon degenerated into a series of single combats, but his first line fought it out alone because the second line refused for some reason to advance in support. Believing themselves abandoned, the Carthaginians turned and fled toward the rear, but the second line refused to let them pass. The result was a fight among Carthaginians as the young hastati veterans pressed down on them. When the principes moved forward to support their first line, both the Carthaginian lines then broke into retreat into the third line, which also refused to let them through. All of this resulted in a massive number of dead and wounded as well as incredible confusion on the Carthaginian side. With the oldest veteran triarii advancing and joining the assault, the relatively well organized Romans were able to launch a coordinated attack on their foe. The solid Carthaginian third line stood and fought well, but they were badly outnumbered by this time.
Still, the battle seemed in doubt as Hannibal’s infantry matched the quality of fighting of the Romans. The death blow, however, came from behind. Having given up their respective pursuits, both the Roman and Numidian cavalries returned to the battle and struck the Carthaginian rear. This proved too much, and the Romans began a slaughter. For a loss of 1,500 men killed and probably about 4,000 wounded, the Romans killed 20,000 Carthaginians and captured another 15,000. Hannibal, accompanied by a handful of retainers, fled.
Results
Scipio decided against laying Carthage under siege. It was a massive and well-situated city on the end of a strongly fortified peninsula. He lacked the siege engines he would need and the necessary supplies. Further, fearing he would be recalled to Rome before the siege was finished, Scipio decided against allowing anyone else to take the credit for capturing the city. He also felt that it was the Roman way to offer generous terms. He demanded (1) that Carthage hand over all but ten of its warships and all the elephants; (2) that Carthage fight no war against anyone without Roman approval; (3) recognition of Massinissa as king of Numidia; and (4) an indemnity of 10,000 silver talents (approximately 500,000 pounds). This was fairly lenient, considering that Rome could have annexed all of Carthage’s merchant fleet and, with it, access to its markets.
Hannibal, in spite of his defeat at Zama, was elected to lead the new Carthaginian government. Under his wise leadership, Carthage paid off its indemnity early and rebounded strongly from the very long war. He provoked Roman jealousy, however, and he spent the rest of his life after 196 b.c. in the courts of various kings as military advisor before finally committing suicide rather than fall into Roman hands. Hannibal’s campaign in Italy has long been recognized as one of the genuine masterpieces of military history, but in the end he was a victim of his own success. Scipio, on the other hand, was ultimately surnamed Africanus for his victory over Hannibal. The meeting of these two generals marked one of those rare occasions in warfare when the best military minds of an era face each other. Probably not until Wellington faced Napoleon at Waterloo was there another such monumental encounter.
Peace between the two powers lasted 50 years, but, when Massinissa demanded too much territory at Carthage’s expense, he provoked an invasion in 151 b.c. Because this was undertaken without Rome’s consent, the Roman government went to war. The Carthaginians immediately announced their willingness to stop fighting, but would not abandon their capital city. After a 3-year siege, Carthage finally fell to Roman forces in 146 b.c. The city was razed, and Utica became the provincial capital of the survivors, who came under the direct rule of Rome. Roman control over this region guaranteed grain supplies for the empire for centuries to come.
The Roman victory at Zama catapulted the victors from a regional to an international power. Already enlarged by the acquisition of Spain, Roman control over Sicily, northern Italy (Cisalpine Gual), Corsica, and Sardinia meant that the entire western Mediterranean was under its direct or indirect control. Although this was an empire in fact, not until Caesar Augustus came to rule in Rome in 31 b.c. was it formally recognized as such. This political and economic dominance was further solidified in 168 b.c. with the Roman victory over Macedonia at Pydna. That victory placed virtually the entire Mediterranean under Rome’s sway. All that the Roman Empire became was launched at Zama. Had Hannibal won the day, Carthage would probably have continued the war. Although the Carthaginian government was always niggardly in its support of Hannibal during his time in Italy, had he returned to Italy with a victorious army, the capture of the city of Rome was not beyond the realm of possibility. Whether a Carthaginian Empire in Europe would have resulted is problematic, but it certainly would have made sure that Spain was returned to its control. That may have set up an interesting rivalry over Gaul, and the future of western Europe may have had Phoenician roots from Carthage rather than Latin and Greek influence from Rome.
