Acknowledgements
MANY FAMILY MEMBERS and friends contributed to the final form of this book. I must pay particular thanks once again to Ian Hughes who read and commented on successive versions of the manuscript. Others who greatly enhanced the clarity of the final text include Dr Hugh Deeks and Averil Goldsworthy. Conversations over several years and with many other people have helped to modify and refine my ideas about the battle itself and the nature of combat in this period. There are too many to mention them all, but I ought to thank in particular Professor Philip Sabin and Dr Louis Rawlings.
In addition, I must thank the Series Editor, Professor Richard Holmes, for his thought-provoking comments on an earlier draft of the text. Finally, praise should also go to Keith Lowe for his continued efforts.
Introduction
ON 2 AUGUST 216 BC the Carthaginian General Hannibal won one of the most complete battlefield victories in history. Outnumbered nearly two to one, his heterogeneous army of Africans, Spaniards and Celts not merely defeated, but virtually destroyed the Roman army opposing them. By the end of the day, nearly 50,000 Roman and Allied soldiers lay dead or were dying in an area of a few square kilometres, whilst between ten and twenty thousand more were prisoners. Less than 20% of one of the largest armies ever fielded by the Roman State survived to reform over the next few weeks. Cannae became the yardstick by which the Romans measured later catastrophes, but only one or two defeats in their history were ever judged to have been as bad. The scale of the losses at Cannae was unrivalled until the industrialised slaughter of the First World War.
Most battles from the Ancient World are now all but forgotten, for military as well as civil education has ceased to be based fundamentally on the Classics. Yet Cannae is still regularly referred to in the training programmes of today’s army officers. Hannibal’s tactics appear almost perfect, the classic example of double envelopment, and ever since many commanders have attempted to reproduce their essence and their overwhelming success. Nearly all have failed. Cannae was the largest in a series of defeats Hannibal inflicted on the Romans, but, though he never lost a major engagement in Italy, eventually he was forced to evacuate his army and Carthage lost the war. The genius of his tactics at Cannae should not obscure the stages of the battle when things could easily have gone the other way and a great Roman victory resulted. Hannibal won the battle through not only his dynamic leadership and the high quality of his army, but also because of a good deal of luck. Cannae was not an exercise in pure tactics, but, like all battles, a product both of the military doctrines and technology of the time and the peculiar circumstances of a specific campaign.
The aim of this book is to place Cannae firmly within the perspective of the Second Punic War and the nature of warfare in the third century BC. The events of this period are poorly recorded in comparison with more recent conflicts, and no official documents survive from either side for the Cannae campaign. Instead we have the narratives of historians, written anytime from seventy to several hundred years after the events they describe. Frequently these sources contradict one another, or fail to tell us things we would wish to know, and so there are many aspects of the campaign and battle which cannot be reconstructed with absolute certainty. Two accounts provide us with the greater part of our information, and it is worth briefly considering these.
The earliest and best was written by the Greek historian Polybius in the second half of the second century BC. Polybius was a one of a group of hostages sent to Rome after the Third Macedonian War (172-168 BC). He became an intimate of Scipio Aemilianus, the grandson of one of the Roman commanders at Cannae, following him on campaign in the Third Punic War (149-146 BC) and witnessing the final destruction of Carthage. Polybius produced a Universal History describing events throughout the Mediterranean down until his own day, and its main theme was to explain for Greek audiences how Rome had so quickly emerged as the dominant world power. His narrative is generally sober and analytical, and he provides us with by far the best description of the Roman army. However, whilst willing to criticise the Romans in general, he is invariably sympathetic to all of the ancestors by blood or adoption of Scipio Aemilianus. Polybius’ account survives intact for the battle itself, but then breaks off and only small fragments survive for the remaining years of the war.
The other main account was written in Latin by Livy in the late first century B
C as part of his History of Rome from the Foundation of the City. His narrative is fiercely patriotic, stylistically elegant and intensely dramatic, but far less critically rigorous than that of Polybius. Livy used the Greek historian as one of his sources, but also drew upon a range of other traditions, most very favourable to the Romans and many celebrating the deeds of particular aristocratic families. He is useful because he provides information about some things, for instance Roman elections and politics, which are passed over very briefly by Polybius. In addition Livy’s narrative survives intact for the entire Second Punic War, making him our main source for the aftermath of the battle.
Other sources provide some additional information, but all were written considerably later. Appian wrote a Roman history around the turn of the first and second centuries AD, but his account of Cannae makes very little sense and is of dubious reliability. Around the same time, Plutarch produced a collection of biographical Lives, some of which include accounts of the period. Such late sources need to be used with extreme caution, but it is possible that they preserved a few accurate details absent from the surviving portions of our earlier sources.
ONE
Carthage, Rome and The Punic Wars
AT THE START of the third century BC the Republic of Carthage was the wealthiest and most powerful state in the Western Mediterranean. It had been founded, probably in the late eighth century, by Phoenician settlers from Tyre on the coast of modern-day Lebanon. The Phoenicians were the great maritime traders of the ancient world–the Romans knew them as ‘Poeni’, hence Punic–and eventually Carthage came to control trade in the West, dominating the coasts of Africa and Spain as well as Sicily, Sardinia, Corsica and the lesser islands of the region. The scientific exploitation of the then fertile agricultural land of North Africa combined with the profits of trade to make the city fabulously rich. However, this wealth was not evenly distributed and remained almost entirely in the hands of the small number of Carthaginian citizens, and especially the aristocracy. Preserving their Semitic language, religion and culture, and jealously guarding the privileges of citizenship, the descendants of the Punic settlers remained a distinct élite. In contrast the indigenous population, especially the Libyans, were heavily taxed, exploited as agricultural labour and military manpower, and had no real share in the profits of empire.
Until 265 BC Rome remained a purely Italian power, and had by this time subjugated all of the Peninsula south of the River Po. From very early in their history the Romans displayed a remarkable talent for absorbing others. Enemies defeated in war became subordinate allies and in future supplied men and material for the next generation of Rome’s wars. The Romans were unique in the ancient world in their willingness to grant citizenship to outsiders. Some former enemies became full citizens or citizens with limited rights, whilst others were granted the lesser rights of Latins, each grade being a legal status, rather than reflecting actual ethnic and linguistic distinctions. Each community was tied directly to Rome in a treaty which made clear both its rights and its obligations. The allies helped to fight Rome’s wars and shared, at least to a limited extent, in their profits. As Rome expanded its population grew. The total land owned by Carthaginian and Roman citizens respectively in 265 BC was probably roughly equivalent in size, but the numbers of the former were tiny in comparison to the latter. The obligation of all citizens and allies possessing a minimum property qualification to serve in Rome’s armies gave the Republic immense reserves of military manpower.1
In 265 BC the Romans for the first time sent an army overseas, when an expedition responded to an appeal to intervene in the affairs of a Sicilian city. Carthage, who had long possessed a presence in the island, even if it had never managed to subjugate it completely, resented this intrusion and responded with force. The result was the First Punic War (264–241 BC), an arduous struggle fought on a far bigger scale than either side could have imagined when they so lightly entered the conflict. The war was mainly fought in and around Sicily, with the most important battles occurring at sea, where fleets of hundreds of oared warships clashed in confused, swirling mêlées. In 256 the Romans invaded Africa and threatened Carthage itself, but the initial willingness of the Punic authorities to seek peace withered when faced with what they considered to be extremely harsh Roman demands. The Carthaginians fought on, and managed to destroy the Roman expeditionary force in battle, winning their only major victory on land in the entire war. In the naval war the Punic fleet proved unable to turn its greater experience to tangible advantage, losing all but one of the major battles. Losses were appalling on both sides, the Romans losing hundreds of ships to bad weather, although relatively few to enemy action. In the last years of the war both sides were close to utter exhaustion, their treasuries drained by the costs of maintaining the struggle. In 241 BC a Roman fleet, paid for largely by voluntary loans made by individuals to the state, defeated the last Punic fleet at the battle of the Aegates Islands. Carthage no longer had the resources to continue the struggle and had no choice but to accept peace on terms dictated by Rome, giving up her last territory and influence in Sicily and paying a heavy indemnity.2
THE SECOND PUNIC WAR
The peace between Rome and Carthage lasted almost as long as the First War. From the very beginning some Carthaginians resented the surrender and believed it to be unnecessary. Foremost amongst these was Hamilcar Barca, the commander of the army in Sicily, who for nearly a decade had waged a war of skirmishes, raid and ambush with the Romans. Hamilcar had never fought a pitched battle, and his victories over the Romans were small in scale, but he believed, or affected to believe, that he could have continued to fight for years, and perhaps eventually worn the enemy down. Resigning his command in a public display of disgust at the surrender, he left others to disband his mercenary army. The task was botched, and the mercenaries first mutinied and then rebelled, taking much of the Libyan population with them, for Carthaginian rule, always harsh, had become especially burdensome as they struggled to fund the war with Rome. The resulting Mercenary War was fought with appalling cruelty by both sides and came very close to destroying Carthage. In the end it was ruthlessly suppressed by Hamilcar in a series of campaigns which demonstrated his skill as a commander far more clearly than had the fighting in Sicily during the war with Rome.
The Romans honoured the treaty and did not at first exploit the weakness of their former enemy, rejecting appeals for an alliance from Carthage’s rebellious allies. However, in the closing stages of the rebellion, they seized Sardinia and threatened a renewal of war if Carthage resisted. The Roman action was blatantly cynical and emphasized just how far Carthaginian power had declined since their defeat. More than anything else, this added to the deep sense of humiliation and resentment felt by much of the population. In 237 Hamilcar Barca was given command of the Carthaginian province in Spain and immediately began a programme of expansion. Some areas, especially those containing valuable mineral deposits, were taken under direct rule, whilst others were brought under Punic influence. All of the campaigns and diplomacy were carried out by members of the Barcid family. When Hamilcar was killed in battle in 229, he was succeeded by his son-in-law, Hasdrubal, who in turn was followed by Hamilcar’s son Hannibal in 221. It is now hard to know how much independence the Barcids enjoyed in Spain, so that they have been variously depicted as loyal servants obeying the instructions of the Punic authorities and as semi-independent Hellenistic princes. Expansion in Spain brought great wealth–the coins minted in considerable numbers by the Barcids have an especially high silver content–and increased access to the fertile recruiting ground offered by the warlike Spanish tribes. The campaigns to achieve this expansion helped to create the nucleus of a highly efficient army, hardened by long experience of fighting under familiar officers. Once again, it is difficult to know to what extent these benefits were to the Republic as a whole, or served to further the ambitions of Hamilcar and his family.
The Romans viewed the growth of Punic power in Spain
with great suspicion. In 226 BC a Roman embassy forced Hasdrubal to agree to a treaty barring Carthage from expanding beyond the River Ebro. The border of the Punic province was still some way south of the river and thus this was not an especially harsh measure, but it demonstrated the Romans’ belief that they were free to impose restrictions on their former enemy whenever they wished. The treaty placed no restriction at all on Roman activity. In 220 Hannibal supported one of the tribes allied to Carthage in a dispute with the city of Saguntum. This was south of the Ebro, but at some point had become an ally of Rome, to whom the Saguntines swiftly appealed for protection. The Romans sent an embassy to instruct Hannibal to abandon his siege of the city, probably expecting him to back down as the Carthaginians had always done in the past. Hannibal continued the assault and finally captured Saguntum in 219 BC after an eight month siege, sacking it and enslaving the population. The Romans protested to Carthage and, when the authorities there refused to condemn Hannibal and hand him over for punishment, declared war at the beginning of 218 BC.3
HANNIBAL BARCA
Hannibal was in his late twenties when he led his army out from his base at New Carthage to begin the Italian expedition in the spring of 218 BC. He was already an experienced soldier, having accompanied the army on campaign under his father and brother-in-law, serving in a variety of increasingly senior roles as soon as he was old enough. Since his elevation to the command in Spain in 221, he had already begun to display the speed of action, tactical genius and inspirational leadership which were subsequently to dazzle his Roman opponents. Our sources tell us a good deal about what Hannibal actually did, allowing us to appreciate his extraordinary talent, but provide little reliable information about his character. No source has survived written from the Carthaginian perspective, although we know that at least two Greek scholars, one of them Hannibal’s tutor the Spartan Sosylus, accompanied his army and recorded its campaigns. Hannibal had some knowledge of Greek culture and history, but it is unclear how important a part this played in his life or to what extent he remained firmly the product of his own Semitic culture.4
