The Second Punic War: 218-202 BC

Following its defeat in the First Punic War, Carthage rebuilt its strength by expanding its empire in Spain. Growing increasingly anxious, the Romans had imposed a treaty on Carthage not to expand their empire past the Ebro river in Spain. However, when a small city in Spain, Saguntum, approached Rome asking for Roman friendship and alliance, the Romans couldn't resist having a friendly ally right in the heart of the Carthaginian Iberian empire.

A few years later, however, in 221 BC, a young man, only twenty-five years old, assumed command over Carthaginian Spain: Hannibal. At first, Hannibal gave the Saguntines what they wished in order to avoid coming into conflict with Rome. But the Saguntines were flush with confidence in their new alliance and began playing politics with other Spanish cities. Hannibal, despite direct threats from Rome, attacked Saguntum and conquered it.

The Romans attempted to solve the problem with diplomacy and demand that Carthage dismiss Hannibal and send him to Rome. When Carthage refused, the second Punic War began in 218 BC. Rome, however, was facing a formidable opponent; in the years following the first Punic War, Carthage had created a powerful empire in Spain with a terrifyingly large army. Hannibal marched that terrible army out of Spain and across Europe and, in September of 218, he crossed the Alps with his army (which included war elephants) and invaded Italy from the north. Although his army was tired from the journey, he literally smashed the Roman armies he encountered in northern Italy. Within two months, he had conquered the whole of northern Italy, with the exception of two cities. These spectacular victories brought a horde of northern Italian men from the north to help him, fifty thousand or more; his victory over Rome, as he saw it, would be guaranteed if he could convince Roman allies and subject cities to join Carthage.

The Romans were divided as to whether they could beat Hannibal in open warfare and they knew that he and his army were alone and far from any supplies. Despite Hannibal's certainty that Roman allies would join him, the allies remained faithful to Rome. So on the eve of his invasion of Rome, Hannibal steered south. The Romans, desperate because of their losses, asked Quintus Fabius Maximus to become absolute dictator of Rome. Fabius determined to avoid open warfare at any cost and simply shadowed and harassed the Carthaginian army until they were weak enough to be engaged with openly. His instinct was to wait out Hannibal; he was hated for this policy—the Romans called him "The Delayer" and eventually removed him from power. But when Hannibal marched into Cannae in southern Italy and started decimating the countryside in 216 BC, the two inexperienced consuls which had replaced Fabius as generals of the army sent an army of eighty thousand soldiers against him. This army, vastly outnumbering the Carthaginian army, was completely wiped out by Hannibal: the largest defeat Rome ever suffered. The battle of Cannae had proven that Fabius was right all along to avoid direct battles, so the Romans went back to his strategy of waiting out Hannibal. Roman allies in the south of Italy literally ran to Hannibal's side; the whole of Sicily allied itself with the Carthaginians. In addition, the king of Macedon, Philip V, who controlled most of the mainland of Greece, allied himself with Hannibal and began his own war against Roman possessions in 215 BC.

The situation looked bad for the Romans; however, none of the central Italian allies had gone over to Hannibal's side after Cannae. The Romans had been chastened by their defeat and absolutely refused to go against Hannibal, whose army moved around the Italian countryside absolutely unopposed. Hannibal, however, was weak in numbers and in equipment. He didn't have enough soldiers to lay siege to cities such as Rome, and he didn't have either the men or equipment to storm those cities by force. All he could do was roam the countryside and lay waste to it. In 211, he marched right up the walls of Rome, but he never laid siege to it. The Romans, however, very shrewdly decided to fight the war through the back door. They knew that Hannibal was dependent on Spain for future supplies and men, so they appointed a young, strategically brilliant man as proconsul and handed him the imperium over Spain. This move was unconstitutional, for this young man had never served as consul. His name: Publius Cornelius Scipio (237-183 BC). Scipio, who would later be called Scipio Africanus for his victory over Carthage (in Africa), by 206 had conquered all of Spain, which was converted into two Roman provinces. Hannibal was now left high and dry in Italy.

Scipio then crossed into Africa in 204 BC and took the war to the walls of Carthage itself. This forced the Carthaginians to sue for peace with Rome; part of the treaty demanded that Hannibal leave the Italian peninsula. Hannibal was one of the great strategic generals in history; all during his war with Rome he never once lost a major battle, although he had lost a couple small skirmishes. Now, however, he was forced to retreat; he had, despite winning every battle, lost the war. When he returned to Carthage, the Carthaginians took heart and rose up against Rome in one last gambit in 202 BC. At Zama in northern Africa, Hannibal, fighting against Scipio and his army, met his first defeat. Rome reduced Carthage to a dependent state; Rome now controlled the whole of the western Mediterranean including northern Africa.

This was the defining historical experience of the Romans. They had faced certain defeat with toughness and determination and had won against overwhelming odds. Their system of alliances had held firm; while Hannibal had depended on the allies running to his side, only the most remote Roman allies, those in the south and Sicily, left the Roman alliance. For the rest of Roman history, the character of being Roman would be distilled in the histories of this seemingly desperate war against Carthage. The Second Punic War turned Rome from a regional power into an international empire: it had gained much of northern Africa, Spain, and the major islands in the western Mediterranean. Because Philip V of Macedon had allied himself with Hannibal and started his own war of conquest, the second Punic War forced Rome to turn east in wars of conquest against first Philip and then other Hellenistic kingdoms. The end result of the second Punic War, in the end, was the domination of the known world by Rome.
