Punic Wars


The Punic Wars were a series of three wars fought between the states of Rome and Carthage between 264 and 146 BC. The First Punic War broke out in Sicily as a result of Rome's expansionary attitude combined with Carthage's proprietary approach to the island. At the start of the war, Carthage was the dominant power of the Western Mediterranean, with an extensive maritime empire. Rome was a rapidly ascending power in Italy, but it lacked the naval power of Carthage. The fighting took place primarily on the Mediterranean island of Sicily and its surrounding waters, and also in North Africa, Corsica and Sardinia. It lasted 23 years, and after immense material and human losses on both sides the Carthaginians were defeated. By the terms of the peace treaty agreed Carthage paid large reparations and Sicily was annexed as a Roman province. Henceforth Rome was the leading military power in the western Mediterranean, and increasingly the Mediterranean region as a whole. The end of the war sparked a major but unsuccessful revolt within the Carthaginian Empire.
The Second Punic War witnessed Hannibal's crossing of the Alps in 218 BC, followed by a prolonged but ultimately failed campaign of Carthage's Hannibal in mainland Italy. By the end of the Third Punic War, after more than a hundred years and the loss of many hundreds of thousands of soldiers from both sides, Rome had conquered Carthage's empire, completely destroyed the city, and became the most powerful state of the Western Mediterranean.
With the end of the Macedonian Wars – which ran concurrently with the Punic Wars – and the defeat of the Seleucid King Antiochus III the Great in the Roman–Seleucid War in the eastern sea, Rome emerged as the dominant Mediterranean power and one of the most powerful cities in classical antiquity. The Roman victories over Carthage in these wars gave Rome a preeminent status it would retain until the 5th century AD.

Primary sources

The main source for almost every aspect of the Punic Wars is the historian Polybius, a Greek sent to Rome in 167 BC as a hostage. His works include a now-lost manual on military tactics, but he is now known for The Histories, written sometime after 146 BC. Polybius's work is considered broadly objective and largely neutral as between Carthaginian and Roman points of view. Polybius was an analytical historian and wherever possible personally interviewed participants, from both sides, in the events he wrote about. He accompanied the Roman general Scipio Aemilianus during his campaign in North Africa which resulted in the Roman victory in the Third Punic War.
The accuracy of Polybius's account has been much debated over the past 150 years, but the modern consensus is to accept it largely at face value, and the details of the war in modern sources are largely based on interpretations of Polybius's account. The modern historian Andrew Curry sees Polybius as being "fairly reliable"; while Craige Champion describes him as "a remarkably well-informed, industrious, and insightful historian".
Other, later, ancient histories of the war exist, although often in fragmentary or summary form. Modern historians usually take into account the writings of various Roman annalists, some contemporary; the Sicilian Greek Diodorus Siculus; the later Roman historians Livy, Plutarch, Appian and Dio Cassius. The classicist Adrian Goldsworthy states "Polybius' account is usually to be preferred when it differs with any of our other accounts". Other sources include coins, inscriptions, archaeological evidence and empirical evidence from reconstructions such as the trireme Olympias.

Background and origin

The Roman Republic had been aggressively expanding in the southern Italian mainland for a century before the First Punic War. It had conquered peninsular Italy south of the River Arno by 272 BC, when the Greek cities of southern Italy submitted at the conclusion of the Pyrrhic War. During this period Carthage, with its capital in what is now Tunisia, had come to dominate southern Spain, much of the coastal regions of North Africa, the Balearic Islands, Corsica, Sardinia, and the western half of Sicily in a military and commercial empire.
Beginning in 480 BC, Carthage had fought a series of inconclusive wars against the Greek city states of Sicily, led by Syracuse. By 264 BC Carthage and Rome were the preeminent powers in the western Mediterranean. The two states had several times asserted their mutual friendship via formal alliances: in 509 BC, 348 BC and around 279 BC. Relationships were good, with strong commercial links. During the Pyrrhic War of 280–275 BC, against a king of Epirus who alternately fought Rome in Italy and Carthage on Sicily, Carthage provided materiel to the Romans and on at least one occasion used its navy to ferry a Roman force. According to the classicist Richard Miles, Rome's expansionary attitude after southern Italy came under its control combined with Carthage's proprietary approach to Sicily caused the two powers to stumble into war more by accident than design. The immediate cause of the war was the issue of control of the independent Sicilian city state of Messana. In 264 BC Carthage and Rome went to war, starting the First Punic War.

Opposing forces

Armies

Most male Roman citizens were eligible for military service and would serve as infantry, a better-off minority providing a cavalry component. Traditionally, when at war the Romans would raise two legions, each of 4,200 infantry and 300 cavalry. A few infantry served as javelin-armed skirmishers, while the balance were equipped as heavy infantry, with body armour, a large shield and short thrusting swords. They were divided into three ranks, of which the front rank also carried two javelins, while the second and third ranks had a thrusting spear instead. Both legionary sub-units and individual legionaries fought in relatively open order. It was the long-standing Roman procedure to elect two men each year, known as consuls, to each lead an army. An army was usually formed by combining a Roman legion with a similarly sized and equipped legion provided by their Latin allies.
Carthaginian citizens only served in their army if there was a direct threat to the city. When they did they fought as well-armoured heavy infantry armed with long thrusting spears, although they were notoriously ill-trained and ill-disciplined. In most circumstances Carthage recruited foreigners to make up its army. Many would be from North Africaa majority during the First Punic Warwhich provided several types of fighters including: close-order infantry equipped with large shields, helmets, short swords and long thrusting spears; javelin-armed light infantry skirmishers; close-order shock cavalry carrying spears; and light cavalry skirmishers who threw javelins from a distance and avoided close combat. Both Spain and Gaul provided large numbers of experienced infantry, especially during the Second Punic War; they were mostly unarmoured troops who would charge ferociously, but had a reputation for breaking off if a combat was protracted. The close order Libyan infantry and the citizen-militia would fight in a tightly packed formation known as a phalanx. On occasion some of the infantry would wear captured Roman armour, especially among Hannibal's troops. Slingers were frequently recruited from the Balearic Islands. The Carthaginians also employed war elephants; North Africa had indigenous African forest elephants at the time.
Garrison duty and land blockades were the most common operations for both armies. When armies were campaigning, surprise attacks, ambushes and strategems were common. More formal battles were usually preceded by the two armies camping a mile or two apart for days or weeks; sometimes forming up in battle order each day. If neither commander could see an advantage, both sides might march off without engaging. Forming up in battle order was a complicated and premeditated affair, which took several hours. Infantry were usually positioned in the centre of the battle line, with light infantry skirmishers to their front and cavalry on each flank. Many battles were decided when one side's infantry force was attacked in the flank or rear and they were partially or wholly enveloped.

Navies

, meaning "five-oarsmen", provided the workhorses of the Roman and Carthaginian fleets throughout the Punic Wars. So ubiquitous was the type that Polybius uses it as a shorthand for "warship" in general. A quinquereme carried a crew of 300: 280 oarsmen and 20 deck crew and officers. It would also normally carry a complement of 40 marines, if battle was thought to be imminent this would be increased to as many as 120. In 260 BC Romans set out to construct a fleet and used a shipwrecked Carthaginian quinquereme as a blueprint for their own.
As novice shipwrights, the Romans built copies that were heavier than the Carthaginian vessels, and so slower and less manoeuvrable. Getting the oarsmen to row as a unit, let alone to execute more complex battle manoeuvres, required long and arduous training. At least half of the oarsmen would need to have had some experience if the ship was to be handled effectively. As a result, the Romans were initially at a disadvantage against the more experienced Carthaginians. To counter this, the Romans introduced the corvus, a bridge wide and long, with a heavy spike on the underside, which was designed to pierce and anchor into an enemy ship's deck. This allowed Roman legionaries acting as marines to board enemy ships and capture them, rather than employing the previously traditional tactic of ramming.
All warships were equipped with rams, a triple set of bronze blades weighing up to positioned at the waterline. In the century prior to the Punic Wars, boarding had become increasingly common and ramming had declined, as the larger and heavier vessels adopted in this period lacked the speed and manoeuvrability necessary to ram, while their sturdier construction reduced the ram's effect even in case of a successful attack. The Roman adaptation of the corvus was a continuation of this trend and compensated for their initial disadvantage in ship-manoeuvring skills. The added weight in the prow compromised both the ship's manoeuvrability and its seaworthiness, and in rough sea conditions the corvus became useless; part way through the First Punic War the Romans ceased using it.

First Punic War, 264–241 BC

Course

Much of the war was to be fought on, or in the waters near, Sicily. Away from the coasts its hilly and rugged terrain made manoeuvring large forces difficult and favoured the defence over the offence. Land operations were largely confined to raids, sieges and interdiction; in 23 years of war on Sicily there were only two full-scale pitched battles.

Sicily, 264–257 BC

The war began with the Romans gaining a foothold on Sicily at Messana. The Romans then pressed Syracuse, the only significant independent power on the island, into allying with them and laid siege to Carthage's main base at Akragas on the south coast. A Carthaginian army of 50,000 infantry, 6,000 cavalry and 60 elephants attempted to lift the siege in 262 BC, but was heavily defeated at the Battle of Akragas. That night the Carthaginian garrison escaped and the Romans seized the city and its inhabitants, selling 25,000 of them into slavery.
The land war on Sicily reached a stalemate as the Carthaginians focused on defending their well-fortified towns and cities; these were mostly on the coast and so could be supplied and reinforced without the Romans being able to use their superior army to interfere. The focus of the war shifted to the sea, where the Romans had little experience; on the few occasions they had previously felt the need for a naval presence they had usually relied on small squadrons provided by their Latin or Greek allies. The Romans built a navy to challenge Carthage's, and using the corvus inflicted a major defeat at the Battle of Mylae in 260 BC. A Carthaginian base on Corsica was seized, but an attack on Sardinia was repulsed; the base on Corsica was then lost. In 258 BC a Roman fleet heavily defeated a smaller Carthaginian fleet at the Battle of Sulci off the coast of western Sardinia.

Africa, 256–255 BC

Taking advantage of their naval victories the Romans launched an invasion of North Africa in 256 BC, which the Carthaginians intercepted. At the Battle of Cape Ecnomus off the south coast of Sicily the Carthaginians were again beaten; this was possibly the largest naval battle in history by the number of combatants involved. The invasion initially went well and in 255 BC the Carthaginians sued for peace; the proposed terms were so harsh they fought on. At the Battle of Tunis in spring 255 BC a combined force of infantry, cavalry and war elephants under the command of the Spartan mercenary Xanthippus crushed the Romans. The Romans sent a fleet to evacuate their survivors and the Carthaginians opposed it at the Battle of Cape Hermaeum (modern Cape Bon; the Carthaginians were again heavily defeated. The Roman fleet, in turn, was devastated by a storm while returning to Italy, losing most of its ships and over 100,000 men.

Sicily, 255–241 BC

The war continued, with neither side able to gain a decisive advantage. The Carthaginians attacked and recaptured Akragas in 255 BC, but not believing they could hold the city, they razed and abandoned it. The Romans rapidly rebuilt their fleet, adding 220 new ships, and captured Panormus in 254 BC. The next year they lost another 150 ships to a storm. On Sicily the Romans avoided battle in 252 and 251 BC, according to Polybius because they feared the war elephants which the Carthaginians had shipped to the island. In 251 BC the Carthaginians advanced on Panormus, but in a battle outside the walls the Romans drove off the Carthaginian elephants with javelin fire. The elephants routed through the Carthaginian infantry, who were then charged by the Roman infantry to complete their defeat.
Slowly the Romans had occupied most of Sicily; in 249 BC they besieged the last two Carthaginian strongholds Lilybaeum and Drepana in the extreme west. Repeated attempts to storm Lilybaeum's strong walls failed, as did attempts to block access to its harbour, and the Romans settled down to a siege which was to last nine years. They launched a surprise attack on the Carthaginian fleet, but were defeated at the Battle of Drepana; Carthage's greatest naval victory of the war. Carthage turned to the maritime offensive, inflicting another heavy naval defeat at the Battle of Phintias and all but swept the Romans from the sea. It was to be seven years before Rome again attempted to field a substantial fleet, while Carthage put most of its ships into reserve to save money and free up manpower.

Roman victory, 243–241 BC

After more than 20 years of war, both states were financially and demographically exhausted. Evidence of Carthage's financial situation includes their request for a 2,000 talent loan from Ptolemaic Egypt, which was refused. Rome was also close to bankruptcy and the number of adult male citizens, who provided the manpower for the navy and the legions, had declined by 17 percent since the start of the war. Goldsworthy describes Roman manpower losses as "appalling".
The Romans rebuilt their fleet again in 243 BC after the Senate approached Rome's wealthiest citizens for loans to finance the construction of one ship each, repayable from the reparations to be imposed on Carthage once the war was won. This new fleet effectively blockaded the Carthaginian garrisons. Carthage assembled a fleet which attempted to relieve them, but it was destroyed at the Battle of the Aegates Islands in 241 BC, forcing the cut-off Carthaginian troops on Sicily to negotiate for peace.
A treaty was agreed. By its terms Carthage paid 3,200 talents of silver in reparations and Sicily was annexed as a Roman province. Henceforth Rome considered itself the leading military power in the western Mediterranean, and increasingly the Mediterranean region as a whole. The immense effort of repeatedly building large fleets of galleys during the war laid the foundation for Rome's maritime dominance for 600 years.

Interbellum, 243–218 BC

Mercenary War

The Mercenary, or Truceless, War began in 241 BC as a dispute over the payment of wages owed to 20,000 foreign soldiers who had fought for Carthage on Sicily during the First Punic War. When a compromise seemed to have been reached the army erupted into full-scale mutiny under the leadership of Spendius and Matho. 70,000 Africans from Carthage's oppressed dependant territories flocked to join them, bringing supplies and finance. War-weary Carthage fared poorly in the initial engagements, especially under the generalship of Hanno. Hamilcar Barca, a veteran of the campaigns in Sicily, was given joint command of the army in 240 BC, and supreme command in 239 BC. He campaigned successfully, initially demonstrating leniency in an attempt to woo the rebels over. To prevent this, in 240 BC Spendius tortured 700 Carthaginian prisoners to death, and henceforth the war was pursued with great brutality.
By early 237 BC, after numerous setbacks, the rebels were defeated and their cities brought back under Carthaginian rule. An expedition was prepared to reoccupy Sardinia, where mutinous soldiers had slaughtered all Carthaginians. The Roman Senate stated they considered the preparation of this force an act of war, and demanded Carthage cede Sardinia and Corsica, and pay an additional 1,200-talent indemnity. Weakened by 30 years of war, Carthage agreed rather than again enter into conflict with Rome. Polybius considered this "contrary to all justice" and modern historians have variously described the Romans' behaviour as "unprovoked aggression and treaty-breaking", "shamelessly opportunistic" and an "unscrupulous act". These events fuelled resentment in Carthage, which was not reconciled to Rome's perception of its situation. This breach of the recently signed treaty has been considered to be the single greatest cause of war with Carthage breaking out again in 218 BC in the Second Punic War.

Conquest of Iberia

With the suppression of the rebellion, Hamilcar understood that Carthage needed to strengthen its economic and military base if it were to again confront Rome. After the First Punic War, Carthaginian possessions in Iberia were limited to a handful of prosperous coastal cities. Hamilcar took the army which he had led to victory in the Mercenary War to Iberia in 237 BC and carved out a quasi-monarchial, autonomous state in its south east. This gave Carthage the silver mines, agricultural wealth, manpower, military facilities such as shipyards and territorial depth to stand up to future Roman demands with confidence. Hamilcar ruled as a viceroy and was succeeded by his son-in-law, Hasdrubal, in the early 220s BC and then his son, Hannibal, in 221 BC. In 226 BC the Ebro Treaty was agreed with Rome, specifying the Ebro River as the northern boundary of the Carthaginian sphere of influence. A little later Rome made a separate treaty with the city of Saguntum, well south of the Ebro.

Second Punic War, 218–201 BC

In 219 BC a Carthaginian army under Hannibal besieged, captured and sacked Saguntum and in spring 218 BC Rome declared war on Carthage. There were three main military theatres in the war: Italy, where Hannibal defeated the Roman legions repeatedly, with occasional subsidiary campaigns in Sicily and Greece; Iberia, where Hasdrubal, a younger brother of Hannibal, defended the Carthaginian colonial cities with mixed success until moving into Italy; and Africa, where the war was decided.

Italy

Hannibal crosses the Alps, 218–217 BC

In 218 BC there was some naval skirmishing in the waters around Sicily. The Romans beat off a Carthaginian attack and captured the island of Malta. In Cisalpine Gaul, the major Gallic tribes attacked the Roman colonies, causing the Romans to flee to Mutina, which they besieged. A Roman relief army raised the siege, but was then ambushed and besieged itself. An army had been raised to campaign in Iberia, but the Roman Senate detached one Roman and one allied legion from it to send to north Italy. Raising fresh troops to replace these delayed the army's departure for Iberia until September.
Meanwhile, Hannibal assembled a Carthaginian army in New Carthage and led it northwards along the coast in May or June. It entered Gaul and took an inland route, to avoid the Roman allies along the coast. At the Battle of Rhone Crossing, Hannibal defeated a force of local Allobroges that sought to bar his way. A Roman fleet carrying the Iberian-bound army landed at Rome's ally Massalia at the mouth of the Rhone. Hannibal evaded the Romans they continued to Iberia. The Carthaginians reached the foot of the Alps by late autumn and crossed them, surmounting the difficulties of climate, terrain and the guerrilla tactics of the native tribes. The exact route is disputed. Hannibal arrived with 20,000 infantry, 6,000 cavalry, and an unknown number of elephants in what is now Piedmont, northern Italy. The Romans were still in their winter quarters. His surprise entry into the Italian peninsula led to the termination of Rome's planned campaign for the year, an invasion of Africa.

Roman defeats, 218–217 BC

Hannibal's first action was to take the chief city of the hostile Taurini. His army then routed the cavalry and light infantry of the Romans at the Battle of Ticinus. As a result, most of the Gallic tribes declared for the Carthaginian cause, and Hannibal's army grew to over 40,000 men. A large Roman army under the command of Sempronius Longus was lured into combat by Hannibal at the Battle of the Trebia, encircled and destroyed. Only 10,000 Romans out of 42,000 were able to cut their way to safety. Gauls now joined Hannibal's army in large numbers, bringing it up to 60,000 men. The Romans stationed an army at Arretium and one on the Adriatic coast to block Hannibal's advance into central Italy.
In early spring 217 BC, the Carthaginians crossed the Apennines unopposed, taking a difficult but unguarded route. Hannibal attempted without success to draw the main Roman army under Gaius Flaminius into a pitched battle by devastating the area they had been sent to protect. Hannibal then cut off the Roman army from Rome, which provoked Flaminius into a hasty pursuit without proper reconnaissance. Hannibal set an ambush in a defile on the shore of Lake Trasimenus, and in the Battle of Lake Trasimene completely defeated the Roman army and killed Flaminius. 15,000 Romans were killed and 15,000 taken prisoner. 4,000 Roman cavalry from their other army were also engaged and wiped out. The prisoners were sold as slaves if they were Romans, but released if they were from one of Rome's Latin allies. Hannibal hoped that some of these allies could be persuaded to defect, and marched south in the hope of winning over Roman allies among the ethnic Greek and Italic city states.
The Romans, panicked by these heavy defeats, appointed Quintus Fabius Maximus as dictator. Fabius invented the Fabian strategy of avoiding open battle with his opponent, but constantly skirmishing with small detachments of the enemy. This was not popular among the soldiers, the Roman public nor the Roman elite, since he avoided battle while Italy was being devastated by the enemy. Hannibal marched through the richest and most fertile provinces of Italy, hoping that the devastation would draw Fabius into battle, but Fabius refused.

Cannae, 216 BC

At the elections of 216 BC the more aggressive minded Gaius Terentius Varro and Lucius Aemilius Paullus were elected as consuls. The Roman Senate authorized the raising of double-sized armies, a force of 86,000 men, the largest in Roman history up to that point. Paullus and Varro marched southward to confront Hannibal, who accepted battle on the open plain near Cannae. In the Battle of Cannae the Roman legions forced their way through Hannibal's deliberately weak centre, but Libyan heavy infantry on the wings swung around their advance, menacing their flanks. Hasdrubal led Carthaginian cavalry on the left wing and routed the Roman cavalry opposite, then swept around the rear of the Romans to attack the cavalry on the other wing. He then charged into the legions' from behind. As a result, the Roman infantry was surrounded with no means of escape. At least 67,500 Romans were killed or captured.

Roman allies defect, 216–210

Little has survived of Polybius's account of Hannibal's army in Italy after Cannae. Livy gives a fuller record, but according to Goldsworthy "his reliability is often suspect", especially with regard to his descriptions of battles; nevertheless he is the best surviving source for this part of the war. A number of city states in southern Italy allied themselves with Hannibal, or were captured when pro-Carthaginian factions betrayed their defences. These included the large city of Capua and the major port city of Tarentum. Two of the three Samnite cantons also joined the Carthaginian cause. By 214 BC the bulk of southern Italy had turned against Rome.
In 216 BC, a Roman army of 25,000 was ambushed by Boii Gauls northwest of Ariminum at the Battle of Silva Litana and annialated. The news triggered renewed panic in Rome.
When the port city of Locri defected to Carthage in the summer of 215 it was immediately used to reinforce the Carthaginian forces in Italy with soldiers, supplies and war elephants. It was the only time during the war that Carthage reinforced Hannibal. A second force, under Hannibal's youngest brother Mago, was meant to land in Italy in 215 BC but was diverted to Iberia after the Carthaginian defeat there at the Battle of Dertosa.

First Macedonian War, 214–205 BC

During 216 BC the Macedonian king, Philip V, pledged his support to Hannibal – thus initiating the First Macedonian War against Rome in 215 BC. In 211 BC, Rome contained the threat of Macedonia by allying with the Aetolian League, an anti-Macedonian coalition of Greek city states. In 205 BC this war ended with a negotiated peace

Sicily, 213–210 BC

Sicily remained firmly in Roman hands, blocking the seaborne reinforcement and resupply of Hannibal from Carthage. Hiero II, the old tyrant of Syracuse and a staunch Roman ally, died in 215 BC and his successor Hieronymus was discontented with his situation. Hannibal negotiated a treaty whereby Syracuse came over to Carthage, at the price of making the whole of Sicily a Syracusan possession. The Syracusan army proved no match for the Romans, and by spring 213 BC Syracuse was besieged. The siege was marked by the ingenuity of Archimedes in inventing war machines that prevented the Romans from making any gains by traditional methods of siege warfare.
A large Carthaginian army was sent to relieve the city in 213. It captured several Roman-garrisoned towns on Sicily; many Roman garrisons were either expelled or massacred by Carthaginian partisans. In the spring of 212 BC the Romans stormed Syracuse in a surprise night assault and captured several districts of the city. Meanwhile, the Carthaginian army was crippled by plague. After the Carthaginians failed to resupply the city, Syracuse fell in the autumn of 212 BC; Archimedes was killed by a Roman soldier.
Carthage sent more reinforcements to Sicily in 211 BC and went on the offensive. A fresh Roman army attacked the main Carthaginian stronghold on the island, Agrigentum, in 210 BC and the city was betrayed to the Romans by a discontented Carthaginian officer. The remaining Carthaginian-controlled towns then surrendered or were taken through force or treachery and the Sicilian grain supply to Rome and its armies was resumed.

Italy, 209–203 BC

In 205, Mago landed in Genua in north-west Italy with the remnants of his Spanish army. It soon received Gallic and Ligurian reinforcements. Mago's arrival in the north of the Italian peninsula was followed by Hannibal's inconclusive Battle of Crotona in 204 in the far south of the peninsula. Mago marched his reinforced army towards the lands of Carthage's main Gallic allies in the Po Valley, but was checked by a large Roman army and defeated at the Battle of Insubria in 203 BC.

Iberia

Iberia 218–215 BC

The Roman fleet continued on from Massala in the autumn of 218 BC, landing the army it was transporting in north-east Iberia, where it won support among the local tribes. A rushed Carthaginian attack in late 218 BC was beaten off at the Battle of Cissa. In 217 BC 40 Carthaginian and Iberian warships were beaten by 55 Roman and Massalian vessels at the Battle of Ebro River, with 29 Carthaginian ships lost. The Romans lodgement between the Ebro and Pyrenees blocked the route from Iberia to Italy and prevented the despatch of reinforcements from Iberia to Hannibal. The Carthaginian commander in Iberia, Hannibal's brother Hasdrubal marched into this area in 215 BC, offered battle and was defeated at Dertosa, although both sides suffered heavy casualties.

Iberia, 214–209 BC

The Carthaginians suffered a wave of defections of local Celtiberian tribes to Rome. The Scipio brothers captured Saguntum in 212 BC. In 211, they hired 20,000 Celtiberian mercenaries to reinforce their army. Observing that the three Carthaginian armies were deployed apart from each other, the Scipios split their forces. Publius moved to attack Mago Barca near Castulo, while Gnaeus marched on Hasdrubal. This stratagy resulted in the Battle of Castulo and the Battle of Ilorca, usually combined as the Battle of the Upper Baetis. Both battles ended in complete defeat for the Romans, with both of the Scipio brothers being killed, as Hasdrubal had bribed the Romans' mercenaries to desert. The Romans retreated to their coastal stronghold north of the Ebro, from which the Carthaginians failed to expel them. Claudius Nero brought over reinforcements in 210 and stabilized the situation.
. It has been traditionally attributed to Sulla.
In 210 BC, Scipio Africanus arrived in Spain with further reinforcements. In a carefully planned assault in 209 BC, he captured the lightly-defended centre of Carthaginian power in Spain, Cartago Nova. Scipio had the population slaughtered and a vast booty of gold, silver and siege artillery was taken. He liberated the Iberian hostages kept by the Carthaginians to ensure the loyalty of the Iberian tribes, although many of them were subsequently to fight against the Romans.

Roman victory in Iberia, 206–205 BC

In 206 BC, at the Battle of Ilipa, Scipio with 48,000 men, half Italians and half Iberians, defeated a Carthaginian army of 54,500 men and 32 elephants under the command of Mago Barca, Hasdrubal Gisco and Masinissa This sealed the fate of the Carthaginian presence in Iberia. It was followed by the Roman capture of Gades after the city rebelled against Carthaginian rule.
Later that year a dangerous mutiny broke out among Roman troops at their camp at Sucro. It initially attracted support from Iberian leaders, disappointed that Roman forces had remained in the peninsula after the expulsion of the Carthaginians. It was effectively put down by Scipio Africanus. In 205 BC a last attempt was made by Mago to recapture New Carthage when the Roman occupiers were shaken by another mutiny and an Iberian uprising, but he was repulsed. Mago left Spain for Italy with his remaining forces. In 203 BC Carthage succeeded in recruiting at least 4,000 mercenaries from Iberia, despite Rome's nominal control.

Africa

In 213 BC Syphax, a powerful Numidian king in North Africa, declared for Rome. Rome sent advisers to train his soldiers and he waged war against the Carthaginian ally Gala. In 206 BC the Carthaginians ended this drain on their resources by dividing several Numidian kingdoms with him. One of those disinherited was the Numidian prince Masinissa, who was thus driven into the arms of Rome.

Scipio's invasion of Africa, 204–201

In 205 BC Scipio Africanus was given command of the legions in Sicily and allowed to enroll volunteers for his plan to end the war by an invasion of Africa. After landing in Africa in 204 BC, he was joined by Masinissa and a force of Numidian cavalry. Scipio then besieged and failed to take the city of Utica. When a Carthaginian and Numidian relief army under Hasdrubal Barca and Syphax moved to confront him, he mounted a surprise attack and destroyed it. In 203 BC Scipio confronted a second Carthaginian army and destroyed at the Battle of the Great Plains. King Syphax was pursued and taken prisoner at the Battle of Cirta and Masinissa seized a large part of his kingdom with Roman help.
Rome and Carthage entered into peace negotiations, and Carthage recalled Hannibal from Italy. Largely due to mutual mistrust the negotiations came to nothing. Hannibal was placed in command of another army, based his veterans from Italy and newly raised troops from Africa, but with few cavalry. The decisive Battle of Zama followed in October 202 BC. Unlike most battles of the Second Punic War, the Romans had superiority in cavalry and the Carthaginians in infantry. Hannibal attempted to use 80 elephants to break into the Roman infantry formation, but the Romans countered them effectively and they routed back through the Carthaginian ranks. The Roman and Allied Numidian cavalry drove the Carthaginian cavalry from the field. The two sides' infantry fought inconclusively until the Roman cavalry returned and attacked his rear. The Carthaginian formation collapsed; Hannibal was one of the few to escape the field.
The peace treaty imposed on the Carthaginians stripped them of all of their overseas territories, and some of their African ones. An indemnity of 10,000 silver talents was to be paid over 50 years. Hostages were taken. Carthage was forbidden to possess war elephants and its fleet was restricted to 10 warships. It was prohibited from waging war outside Africa, and in Africa only with Rome's express permission. Many senior Carthaginians wanted to reject it, but Hannibal spoke strongly in its favour and it was accepted in spring 201 BC. Henceforth it was clear that Carthage was politically subordinate to Rome.

Interbellum, 201–149 BC

At the end of the war, Masinissa emerged as by far the most powerful ruler among the Numidians. Over the following 48 years he repeatedly took advantage of Carthage's inability to protect its possessions. Whenever Carthage petioned Rome for redress, or permission to take military action, Rome backed its ally, Masinissa, and refused. Masinissa's seizures of and raids into Carthaginian territory became increasingly flagrant. In 151 BC Carthage raised a large army, the treaty notwithstanding, and counter attacked the Numidians. The campaign ended in disaster and the army surrendered. Carthage had paid off its indemnity and was prospering economically, but was no military threat to Rome. Elements in the Roman Senate had long wished to destroy Carthage, and with the breach of the treaty as a casus belli, war was declared in 149 BC.

Third Punic War, 149–146 BC

In 149 BC a Roman army of approximately 50,000 men, jointly commanded by both consuls, landed near Utica, north of Carthage. Rome demanded that if war were to be avoided, the Carthaginians must hand over all of their armaments. Vast amounts of materiel delivered, including 200,000 sets of armour, 2,000 catapults and a large number of warships. This done, the Romans demanded that the Carthaginians burn their city and relocate at least from the sea; the Carthaginians broke off negotiations and set to recreating their armoury.

Siege of Carthage

As well as manning the walls of Carthage, the Carthaginians formed a field army under Hasdrubal, which was based to the south. The Roman army moved to lay siege to Carthage, but its walls were so strong and its citizen-militia so determined that it was unable to make any impact, while the Carthaginians struck back effectively. Their army effectively raided the Roman lines of communication, and in 148 BC Carthaginian fire ships destroyed many Roman vessels. The main Roman camp was in a swamp, which caused an outbreak of disease during the summer. The Romans moved their camp, and their ships, further away; so that they were more blockading than closely besieging the city. The war dragged on into 147 BC.
In early 147 BC Scipio Aemilianus, an adopted grandson of Scipio Africanus who had distinguished himself during the previous two years' fighting, was elected consul and took control of the war. The Carthaginians continued to resist vigorously: they constructed warships and during the summer twice gave battle to the Roman fleet, losing both times. The Romans launched an assault on the walls; after confused fighting they broke into the city, but lost in the dark, withdrew. Hasdrubal and his army withdrew into the city to reinforce the garrison. Roman prisoners were taken and Hasdrubal had them tortured to death on the walls, in view of the Roman army. He was reinforcing the will to resist in the Carthaginian citizens; from this point there could be no possibility of negotiations. Some members of the city council denounced his actions and Hasdrubal had them too put to death and took over control of the city. With no Carthaginian army in the field those cities which had remained loyal went over to the Romans or were captured.
Scipio moved back to a close blockade of the city, and built a mole which cut off supply from the sea. In the spring of 146 BC the Roman army managed to secure a foothold on the fortifications near the harbour. When the main assault began it quickly captured the cities main square, where the legions camped overnight. The next morning the Romans systematically worked their way through the residential part of the city, killing everyone they encountered and firing the buildings behind them. At times the Romans progressed from rooftop to rooftop, to prevent missiles being hurled down on them. It took six days to clear the city of resistance, and on the last day Scipio agreed to accept prisoners. The last holdouts, including Roman deserters in Carthaginian service, fought on from the Temple of Eshmoun and burnt it down around themselves when all hope was gone. The 50,000 Carthaginians, a small part of the pre-war population, were sold into slavery. The notion that Roman forces then sowed the city with salt is a 19th-century invention.

Aftermath

The remaining Carthaginian territories were annexed by Rome and reconstituted to become the Roman province of Africa. Numerous significant Punic cities, such as those in Mauretania, were taken over and rebuilt by the Romans. Utica, the Punic city which changed loyalties at the beginning of the siege, became the capital of the Roman province of Africa. A century later, the site of Carthage was rebuilt as a Roman city by Julius Caesar, and would become one of the main cities of Roman Africa by the time of the Empire.
Rome still exists as the capital of Italy; the ruins of Carthage lie east of modern Tunis on the North African coast.
