Battles of Trebia, Lake Trasimene and Cannae, from left to right

The Battle of Cannae (/ˈkæni/ or /ˈkæneɪ/) was a major battle of the Second Punic War, which took place on August 2, 216 BC near the town of Cannae in Apulia in southeast Italy. The army of Carthage under Hannibal decisively defeated a numerically superior army of the Roman Republic under command of the consuls Lucius Aemilius Paullus and Gaius Terentius Varro. It is regarded as one of the greatest tactical feats in military history and, in terms of the numbers killed, the second greatest defeat of Rome (second to the Battle of Arausio).

Having recovered from their previous losses at Trebia (218 BC) and Trasimene (217 BC), the Romans decided to engage Hannibal at Cannae, with roughly 86,000 Roman and Allied troops. The Romans massed their heavy infantry in a deeper formation than usual while Hannibal utilized the double-envelopment tactic. This was so successful that the Roman army was effectively destroyed as a fighting force. Following the Battle of Cannae, Capua and several other Italian city-states defected from the Roman Republic to Carthage.

Strategic background[link]

Shortly after the start of the Second Punic War, the Carthaginian general Hannibal boldly crossed into Italy by traversing the Alps during the winter. He quickly won two major victories over the Romans at the Battle of Trebia and at the Battle of Lake Trasimene. After suffering these losses, the Romans appointed Fabius Maximus as dictator to deal with the threat. Fabius used attrition warfare against Hannibal, cutting off his supply lines and refusing to engage in pitched battle. These tactics proved unpopular with the Romans. As the Roman people recovered from the shock of Hannibal's initial victories, they began to question the wisdom of the Fabian strategy which had given the Carthaginian army a chance to regroup.^[1] Fabius' strategy was especially frustrating to the majority of Romans who were eager to see a quick conclusion to the war. It was also widely feared that if Hannibal continued plundering Italy unopposed, Rome's allies might doubt Rome's ability to protect them, and defect to Carthage's cause.

Unimpressed with Fabius' strategy, the Roman Senate did not renew his dictatorial powers at the end of his term, and command was given to consuls Gnaeus Servilius Geminus and M. Atilius Regulus. In 216 BC, elections resumed with Gaius Terentius Varro and Lucius Aemilius Paullus elected as consuls, given command of a newly raised army of unprecedented size, and directed to engage Hannibal. Polybius writes:

The Senate determined to bring eight legions into the field, which had never been done at Rome before, each legion consisting of five thousand men besides allies. ...Most of their wars are decided by one consul and two legions, with their quota of allies; and they rarely employ all four at one time and on one service. But on this occasion, so great was the alarm and terror of what would happen, they resolved to bring not only four but eight legions into the field.

— Polybius, The Histories of Polybius^[2]

Estimates of Roman troop numbers[link]

These eight legions, some 40,000 Roman soldiers along with an estimated 2,400 Roman cavalry, formed the nucleus of this massive new army. As each legion was accompanied by an equal number of allied troops, and allied cavalry numbered around 4,000, the total strength of the army which faced Hannibal could not have been much less than 90,000.^[3] However, some have suggested that the destruction of an army of 90,000 troops would be impossible. They argue that Rome probably had 48,000 troops and 6,000 cavalry against Hannibal's 35,000 troops and 10,000 cavalry.^[4] Livy quotes one source stating the Romans only added 10,000 men to their usual army.^[5] While no definitive number of Roman troops exists, all sources agree that the Carthaginian army faced a considerably larger foe.

Roman command[link]

Ordinarily, each of the two consuls would command their own portion of the army, but since the two armies were combined into one, the Roman law required them to alternate their command on a daily basis. It appears that Hannibal had already realized that the command of the Roman army alternated, and planned his strategy accordingly. The traditional account puts Varro in command on the day of the battle and much of the blame for the defeat has been laid on his shoulders.^[6] However his low origins seem to be exaggerated in the sources and Varro may have been made a scapegoat by the aristocratic establishment.^[6] Varro lacked the powerful descendants that Paullus had; descendants who were willing and able to protect his reputation — most notably, Paullus was the grandfather of Scipio Aemilianus, the patron of Polybius.^[7]

Prelude[link]

In the spring of 216 BC, Hannibal took the initiative and seized the large supply depot at Cannae in the Apulian plain. He thus placed himself between the Romans and their crucial source of supply. As Polybius notes, the capture of Cannae "caused great commotion in the Roman army; for it was not only the loss of the place and the stores in it that distressed them, but the fact that it commanded the surrounding district".^[2] The consuls, resolving to confront Hannibal, marched southward in search of the Carthaginian general. After two days’ march, they found him on the left bank of the Aufidus River and encamped six miles (10 km) away.

Reportedly, a Carthaginian officer named Gisgo commented on how much larger the Roman army was. Hannibal replied, "another thing that has escaped your notice, Gisgo, is even more amazing—that although there are so many of them, there is not one among them called Gisgo."^[8]

Consul Varro, who was in command on the first day, is presented by ancient sources as a man of reckless nature and hubris, and was determined to defeat Hannibal. While the Romans were approaching Cannae, a small portion of Hannibal's forces ambushed the Roman army. Varro successfully repelled the Carthaginian attack and continued on his way to Cannae. This victory, though essentially a mere skirmish with no lasting strategic value, greatly bolstered the confidence of the Roman army, perhaps to overconfidence on Varro's part. Paullus, however, was opposed to the engagement as it was taking shape. Unlike Varro, he was prudent and cautious, and he believed it was foolish to fight on open ground, despite the Romans' numerical strength. This was especially true since Hannibal held the advantage in cavalry (both in quality and numerical terms). Despite these misgivings, Paullus thought it unwise to withdraw the army after the initial success, and camped two-thirds of the army east of the Aufidus River, sending the remainder of his men to fortify a position on the opposite side. The purpose of this second camp was to cover the foraging parties from the main camp and harass those of the enemy.^[9]

The two armies stayed in their respective locations for two days. During the second of these two days (August 1), Hannibal, aware that Varro would be in command the following day, left his camp and offered battle. Paullus, however, refused. When his request was rejected, Hannibal, recognizing the importance of the Aufidus' water to the Roman troops, sent his cavalry to the smaller Roman camp to harass water-bearing soldiers that were found outside the camp fortifications. According to Polybius,^[2] Hannibal's cavalry boldly rode up to the edge of the Roman encampment, causing havoc and thoroughly disrupting the supply of water to the Roman camp.^[10]

The battle[link]

Forces[link]

Modern interpretation of a slinger from the Balearic Islands (famous for the skill of their slingers).

Figures for troops involved in ancient battles are often unreliable and Cannae is no exception. Hence the following figures should be treated with caution, especially those for the Carthaginian side.^[11]

The combined forces of the two consuls totaled 80,000 infantry, 2,400 Roman cavalry and 4,000 allied horse (involved in the actual battle) and, in the two fortified camps, 2,600 heavily armed men, 7,400 lightly armed men (a total of 10,000), so that the total strength the Romans brought to the field amounted to approximately 86,400 men. Opposing them was a Carthaginian army composed of roughly 40,000 heavy infantry, 6,000 light infantry, and 10,000 cavalry in the battle itself, irrespective of detachments.^[12]

The Carthaginian army was a combination of warriors from numerous regions. Along with the core of 8,000 Libyans, 8,000 Iberians, 16,000 Gauls (8,000 were left at camp the day of battle) and around 5,500 Gaetulian infantry.^{[citation needed]} Hannibal's cavalry also came from diverse backgrounds. He commanded 4,000 Numidian, 2,000 Spanish, 4,000 Gallic and 450 Liby-Phoenician cavalry. Finally, Hannibal had around 8,000 skirmishers consisting of Balearic slingers and mixed nationality spearmen, bringing Hannibal's army to a total of around 47,950. All of these specific groups brought their respective strengths to the battle. The uniting factor for the Carthaginian army was the personal tie each group had with Hannibal.^[13]

Equipment[link]

Rome's forces used typical Roman equipment including pila (heavy javelins) and hastae (thrusting spears) as weapons as well as traditional helmets, shields, and body armor. On the other hand, the Carthaginian army used a variety of equipment. Iberians fought with swords suited for cutting and thrusting and javelins or various types of spear. For defense, Iberian warriors carried large oval shields and the Falcata. The Gauls were likely wearing no armour at all and the Gaulish weapon was usually a long, slashing sword.^[14] The heavy Carthaginian cavalry carried two javelins and a curved slashing sword with a heavy shield for protection. Numidian cavalry were very lightly equipped, lacking saddles and bridles for their horses, and used no armor but carried a small shield, javelins and possibly a knife or longer blade. Skirmishers acting as light infantry carried either slings or spears. The Balearic slingers, who were famous for their accuracy, carried short, medium, and long slings used to cast stones or bullets. They may have carried a small shield or simple leather pelt on their arms, but this is uncertain. Hannibal himelf was wearing Musculata armour and carried a Falcata as well.^[15]

The equipment of the Libyan line infantry has been much debated. Duncan Head has argued in favor of short stabbing spears.^[16] Polybius states that the Libyans fought with equipment taken from previously defeated Romans. It is unclear whether he meant only shields and armor or offensive weapons as well,^[17] though a general reading suggests he meant the whole panoply of arms and armour, and even tactical organization. Apart from his description of the battle itself, when later discussing the subject of Roman Legion versus Greek Phalanx, Polybius says that "...against Hannibal, the defeats they suffered had nothing to do with weapons or formations" because "Hannibal himself...discarded the equipment with which he had started out (and) armed his troops with Roman weapons".^[18] Dally is inclined to the view that Libyan infantry would have copied the Iberian use of the sword during their fighting there and so were armed similarly to the Romans.^[19] Connolly has argued that they were armed as a pike phalanx.^[20] This has been disputed by Head because Plutarch states they carried spears shorter than the Roman Triarii^[16] and by Dally because they could not have carried an unwieldy pike at the same time as a heavy Roman style shield.^[17]

Tactical deployment[link]

The conventional deployment for armies of the time was to place infantry in the center and deploy the cavalry in two flanking "wings." The Romans followed this convention fairly closely, but chose extra depth rather than breadth for their infantry line, hoping to use this concentration of forces to quickly break through the center of Hannibal's line. Varro knew how the Roman infantry had managed to penetrate Hannibal's center during the Battle of the Trebia, and he planned to recreate this on an even greater scale. The principes were stationed immediately behind the hastati, ready to push forward at first contact to ensure the Romans presented a unified front. As Polybius wrote, "the maniples were nearer each other, or the intervals were decreased... and the maniples showed more depth than front."^[2][21] Even though they outnumbered the Carthaginians, this depth-oriented deployment meant that the Roman lines had a front of roughly equal size to their numerically inferior opponents.

Initial deployment and Roman attack (in red)

To Varro, Hannibal seemed to have little room to manoeuver and no means of retreat as he was deployed with the Aufidus River to his rear. Varro believed that when pressed hard by the Romans' superior numbers, the Carthaginians would fall back onto the river and, with no room to manoeuver, would be cut down in panic. Bearing in mind that Hannibal's two previous victories had been largely decided by his trickery and ruse, Varro had sought an open battlefield. The field at Cannae was indeed clear, with no possibility of hidden troops being brought to bear as an ambush.^[22]

Hannibal, on the other hand, had deployed his forces based on the particular fighting qualities of each unit, taking into consideration both their strengths and weaknesses in devising his strategy.^[23] He placed his Iberians and Gauls in the middle, alternating the ethnic composition across the front line, with the general himself right at the front and center. Hannibal's infantry from Punic Africa was positioned on the wings at the very edge of his infantry line. These infantry were expertly battle-hardened, remained cohesive, and would attack the Roman flanks.

Hasdrubal led the Iberian and Gaulish cavalry on the left (south near the Aufidus River) of the Carthaginian army. Hasdrubal was given about 6,500 cavalry, and Hanno had 3,500 Numidians on the right.

Hannibal intended that his cavalry, comprising mainly medium Hispanic cavalry and Numidian light horse, and positioned on the flanks, would defeat the weaker Roman cavalry and swing around to attack the Roman infantry from the rear as it pressed upon Hannibal's weakened center. His veteran African troops would then press in from the flanks at the crucial moment, and encircle the overextended Roman army.

Hannibal was unworried about his position against the Aufidus River; in fact, it played a major factor in his strategy. By anchoring his army on the river, Hannibal prevented one of his flanks from being overlapped by the more numerous Romans. The Romans were in front of the hill leading to Cannae and hemmed in on their right flank by the Aufidus River, so that their left flank was the only viable means of retreat.^[24] In addition, the Carthaginian forces had maneuvered so that the Romans would face east. Not only would the morning sunlight shine on the Romans, but the southeasterly winds would blow sand and dust into their faces as they approached the battlefield.^[21] Hannibal's unique deployment of his army, based on his perception of the terrain and understanding of the capabilities of his troops, proved decisive.

Subsequent events[link]

As the armies advanced on one another, Hannibal gradually extended the center of his line, as Polybius describes: "After thus drawing up his whole army in a straight line, he took the central companies of Hispanics and Celts and advanced with them, keeping the rest of them in contact with these companies, but gradually falling off, so as to produce a crescent-shaped formation, the line of the flanking companies growing thinner as it was prolonged, his object being to employ the Africans as a reserve force and to begin the action with the Hispanics and Celts." Polybius describes the weak Carthaginian center as deployed in a crescent, curving out toward the Romans in the middle with the African troops on their flanks in echelon formation.^[2] It is believed that the purpose of this formation was to break the forward momentum of the Roman infantry, and delay its advance before other developments allowed Hannibal to deploy his African infantry most effectively.^[25] That being said, while the majority of historians feel that Hannibal's action was deliberate, there are those that have called this account fanciful, and claim that the actions of the day represent either the natural curvature that occurs when a broad front of infantry marches forward, or the bending back of the Carthaginian center from the shock action of meeting the heavily massed Roman center.^[25]

Destruction of the Roman army

When the battle was joined, the cavalry engaged in a fierce exchange on the flanks. Polybius describes the Hispanic and Celtic horse dismounting in what he considers a barbarian method of fighting. When the Hispanic and Gauls got the upper hand, they cut down the Roman cavalry without giving quarter.^[2] On the other flank the Numidians had engaged in a way that merely kept the Roman ally cavalry occupied. When the victorious Hispanic and Gallic cavalry came up, the allied cavalry broke and the Numidians pursued them off the field.^[2]

While the Carthaginians were in the process of defeating the Roman cavalry, the mass of infantry on both sides advanced towards each other in the center of the field. As the Romans advanced, the wind from the East blew dust in their faces and obscured their vision. While the wind itself was not a major factor, the dust that both armies created would have been potentially debilitating to sight.^[21] Although the dust made sight difficult, troops would still have been able to see others in the vicinity. The dust, however, was not the only psychological factor involved in battle. Because of the somewhat distant battle location both sides were forced to fight on little sleep. The Romans faced another disadvantage caused by lack of proper hydration due to Hannibal's attack on the Roman encampment during the previous day. Furthermore, the massive number of troops would have led to an overwhelming amount of background noise. All of these psychological factors made battle especially difficult for the infantrymen.^[26]

Hannibal stood with his men in the weak center and held them to a controlled retreat. The crescent of Hispanic and Gallic troops buckled inwards as they gradually withdrew. Knowing the superiority of the Roman infantry, Hannibal had instructed his infantry to withdraw deliberately, thus creating an even tighter semicircle around the attacking Roman forces. By doing so, he had turned the strength of the Roman infantry into a weakness. Furthermore, while the front ranks were gradually advancing, the bulk of the Roman troops began to lose their cohesion, as they began crowding themselves into the growing gap. Soon they were compacted together so closely that they had little space to wield their weapons. In pressing so far forward in their desire to destroy the retreating and collapsing line of Hispanic and Gallic troops, the Romans had ignored (possibly due to the dust previously mentioned) the African troops that stood uncommitted on the projecting ends of this now reversed-crescent.^[25] This also gave the Carthaginian cavalry time to drive the Roman cavalry off on both flanks and attack the Roman center in the rear. The Roman infantry, now stripped of both its flanks, formed a wedge that drove deeper and deeper into the Carthaginian semicircle, driving itself into an alley that was formed by the African Infantry stationed on the wings.^[27] At this decisive point, Hannibal ordered his African Infantry to turn inwards and advance against the Roman flanks, creating an encirclement of the Roman infantry in one of the earliest known examples of the pincer movement.

When the Carthaginian cavalry attacked the Romans in the rear, and the African flanking echelons had assailed them on their right and left, the advance of the Roman infantry was brought to an abrupt halt. The trapped Romans were enclosed in a pocket with no means of escape. The Carthaginians created a wall and began destroying the entrapped Romans. Polybius claims that, "as their outer ranks were continually cut down, and the survivors forced to pull back and huddle together, they were finally all killed where they stood."

As Livy describes, "So many thousands of Romans were dying ... Some, whom their wounds, pinched by the morning cold, had roused, as they were rising up, covered with blood, from the midst of the heaps of slain, were overpowered by the enemy. Some were found with their heads plunged into the earth, which they had excavated; having thus, as it appeared, made pits for themselves, and having suffocated themselves."^[28] Cowley claims that nearly six hundred legionaries were slaughtered each minute until darkness brought an end to the bloodletting.^[29] Only 14,000 Roman troops managed to escape, most of whom had cut their way through to the nearby town of Canusium.

Casualties[link]

Roman and allied[link]

The Death of Aemilius Paulus by John Trumbull, 1773

Polybius writes that of the Roman and allied infantry, 70,000 were killed, 10,000 captured, and "perhaps" 3,000 survived. He also reports that of the 6,000 Roman and allied cavalry, only 370 survived.^[30]

Livy writes "it is said that 45,500 foot soldiers and 2,700 horsemen were slain in almost equal proportion of citizens and allies".^[31] He also reports that 3,000 Roman and allied infantry and 1,500 Roman and allied cavalry were taken prisoner by the Carthaginians.^[32] Although Livy does not cite his source by name, it is likely to have been Quintus Fabius Pictor, a Roman historian who fought in and wrote on the Second Punic War. It is Pictor whom Livy names when reporting the casualties at the Battle of Trebia.^[33] In addition to the consul Paullus, Livy goes on to record that among the dead were 2 quaestors, 29 of the 48 military tribunes (some of consular rank, including the consul of the previous year, Gnaeus Servilius Geminus, and the former Master of the Horse, Marcus Minucius Rufus), and 80 "senators or men who had held offices which would have given them the right to be elected to the Senate".^[34]

Later Roman (and Greco-Roman) historians all largely follow Livy's figures. Appian gives 50,000 killed and "a great many" taken prisoner.^[35] Plutarch agrees, "50,000 Romans fell in that battle... 4,000 were taken alive".^[36] Quintilian: "60,000 men were slain by Hannibal at Cannae".^[37] Eutropius: "20 officers of consular and praetorian rank, 30 senators, and 300 others of noble descent, were taken or slain, as well as 40,000 foot-soldiers, and 3,500 horse".^[38]

Most modern historians, while rejecting Polybius' figure as flawed, are willing to accept Livy's figure.^[39] Some more recent historians have come up with far lower estimates. Cantalupi proposed Roman losses of 10,500 to 16,000.^[40] Samuels also regards Livy's figure as far too high on the grounds that the cavalry would have been inadequate to prevent the Roman infantry escaping to the rear. He doubts that Hannibal even wanted a high death toll as much of the army consisted of Italians whom Hannibal hoped to win as allies in the future.^[41]

Punic and allied[link]

Livy records Hannibal's losses at "about 8,000 of his bravest men."^[42] Polybius reports 5,700 dead: 4,000 Gauls, 1,500 Spanish and Africans, and 200 cavalry.^[30]

Aftermath[link]

For a brief period of time, the Romans were in complete disarray. Their best armies in the peninsula were destroyed, the few remnants severely demoralized, and the only remaining consul (Varro) completely discredited. It was an appalling catastrophe for the Romans. As the story goes, Rome declared a national day of mourning, as there was not a single person in Rome who was not either related to or acquainted with a person who had died. The Romans became so desperate that they resorted to human sacrifice, twice burying people alive^[44] at the Forum of Rome and abandoning an oversized baby in the Adriatic Sea^[44] (perhaps one of the last recorded instances of human sacrifices the Romans would perform, unless the public executions of defeated enemies dedicated to Mars are counted).

Lucius Caecilius Metellus, a military tribune, is known to have so much despaired in the Roman cause in the aftermath of the battle as to suggest that everything was lost, and called the other tribunes to sail overseas and hire themselves up into the service to some foreign prince.^[12] Afterwards, he was forced by his own example to swear an oath of allegiance to Rome for all time. Furthermore, the Roman survivors of Cannae were later reconstituted as two legions and assigned to Sicily for the remainder of the war as punishment for their humiliating desertion of the battlefield.^[12] In addition to the physical loss of her army, Rome would suffer a symbolic defeat of prestige. A gold ring was a token of membership in the upper classes of Roman society;^[12] Hannibal had his men collect more than 200 gold rings from the corpses on the battlefield, and sent this collection to Carthage as proof of his victory. The collection was poured on the floor in front of the Punic Senate, and was judged to be "three and a half measures."

Hannibal, having gained yet another victory (following the battles of Trebia and Lake Trasimene), had defeated the equivalent of eight consular armies (sixteen legions plus an equal number of allies).^[45] Within just three campaign seasons (20 months), Rome had lost one-fifth (150,000) of the entire population of citizens over seventeen years of age.^[46] Furthermore, the morale effect of this victory was such that most of Southern Italy joined Hannibal's cause. After the Battle of Cannae, the Hellenistic southern provinces of Arpi, Salapia, Herdonia, Uzentum, including the cities of Capua and Tarentum (two of the largest city-states in Italy) all revoked their allegiance to Rome and pledged their loyalty to Hannibal. As Livy notes, "How much more serious was the defeat of Cannae, than those which preceded it can be seen by the behavior of Rome’s allies; before that fateful day, their loyalty remained unshaken, now it began to waver for the simple reason that they despaired of Roman Power."^[47] During that same year, the Greek cities in Sicily were induced to revolt against Roman political control, while the Macedonian king, Philip V, had pledged his support to Hannibal—thus initiating the First Macedonian War against Rome. Hannibal also secured an alliance with the newly appointed King Hieronymus of Syracuse, the only independent leftover in Sicily.

Following the battle, the commander of the Numidian cavalry Maharbal urged Hannibal to seize the opportunity and march immediately on Rome. It is told that the latter's refusal caused Maharbal's exclamation: "Truly the Gods have not bestowed all things upon the same person. Thou knowest indeed, Hannibal, how to conquer, but thou knowest not how to make use of your victory."^[48] Yet Hannibal had good reasons to judge the strategic situation after the battle otherwise than Maharbal did. As the historian Hans Delbrück points out, due to the high numbers of killed and wounded among its ranks, the Punic army was not in a condition to perform a direct assault on Rome. A march to the city on the Tiber would have been a fruitless demonstration that would have nullified the psychological effect of Cannae on the Roman allies. Even if his army was at full strength, a successful siege of Rome would have required Hannibal to subdue a considerable part of the hinterland in order to secure his own and cut the enemy's supplies. Even after the tremendous losses suffered at Cannae, and the defection of a number of her allies, Rome still had abundant manpower to prevent this and at the same time to maintain considerable forces in Iberia, Sicily, Sardinia and elsewhere despite Hannibal's presence in Italy.^[49] Hannibal's conduct after the victories at Trasimene (217 BC) and Cannae (216 BC), and the fact that he first attacked Rome itself only five years later (in 211 BC), suggests that his strategic aim was not the destruction of his foe but to dishearten the Romans by a series of carnages on the battlefields and to wear them down to a moderate peace agreement by stripping them of their allies.^[50][51]

Immediately after Cannae Hannibal sent a delegation led by Carthalo to negotiate a peace treaty with the Senate on moderate terms. Yet despite the multiple catastrophes Rome had suffered, the Roman Senate refused to parley. Instead, they re-doubled their efforts, declaring full mobilization of the male Roman population, and raised new legions enlisting landless peasants and even slaves.^[52] So firm were these measures that the word "peace" was prohibited, mourning was limited to only thirty days, and public tears were prohibited even to women.^[21]:386 The Romans, after experiencing this catastrophic defeat and losing other battles, had at this point learned their lesson. For the remainder of the war in Italy, they would not amass such large forces under one command against Hannibal; instead they would utilize several independent armies, still outnumbering the Punic forces in numbers of armies and soldiers. The war still had occasional battles, but was centered more around taking strongpoints and a constant fighting according to the Fabian strategy. This finally forced Hannibal with his shortage of manpower to retreat to Croton from where he was called to Africa for the battle of Zama, ending the war with a complete Roman victory.

Historical significance[link]

Effects on Roman military doctrine[link]

The Battle of Cannae played a major role in shaping the military structure and tactical organization of the Roman Republican army. At Cannae, the Roman infantry assumed a formation similar to the Greek phalanx. This delivered them into Hannibal's trap, since their inability to maneuver independently from the mass of the army made it impossible for them to counter the encircling tactics employed by the Carthaginian cavalry. Furthermore, the strict laws of the Roman state required that high command alternate between the two consuls—thus restricting strategic consistency.^{[citation needed]}

However, in the years following Cannae, striking reforms were introduced to address these deficiencies. First, the Romans "articulated the phalanx, then divided it into columns, and finally split it up into a great number of small tactical bodies that were capable, now of closing together in a compact impenetrable union, now of changing the pattern with consummate flexibility, of separating one from the other and turning in this or that direction."^{[citation needed]} For instance, at Ilipa and Zama, the principes were formed up well to the rear of the hastati—a deployment that allowed a greater degree of mobility and maneuverability. The culminating result of this change marked the transition from the traditional manipular system to the cohort under Gaius Marius, as the basic infantry unit of the Roman army.

In addition, a unified command came to be seen as a necessity. After various political experiments, Scipio Africanus was made general-in-chief of the Roman armies in Africa, and was assured the continued occupancy of this title for the duration of the war. This appointment may have violated the constitutional laws of the Roman Republic, but, as Hans Delbrück wrote, it "effected an internal transformation that increased her military potentiality enormously" while foreshadowing the decline of the Republic's political institutions. Furthermore, the battle exposed the limits of a citizen-militia army. Following Cannae, the Roman army gradually developed into a professional force: the nucleus of Scipio's army at Zama was composed of veterans who had been fighting the Carthaginians in Hispania for nearly sixteen years, and had been moulded into a superb fighting force.

Status in military history[link]

The Battle of Cannae is as famous for Hannibal's tactics as it is for the role it played in Roman history. Not only did Hannibal inflict a defeat on the Roman Republic in a manner unrepeated for over a century until the lesser-known Battle of Arausio, the battle itself has acquired a significant reputation within the field of military history. As military historian Theodore Ayrault Dodge once wrote:

Few battles of ancient times are more marked by ability... than the battle of Cannae. The position was such as to place every advantage on Hannibal's side. The manner in which the far from perfect Hispanic and Gallic foot was advanced in a wedge in échelon... was first held there and then withdrawn step by step, until it had the reached the converse position... is a simple masterpiece of battle tactics. The advance at the proper moment of the African infantry, and its wheel right and left upon the flanks of the disordered and crowded Roman legionaries, is far beyond praise. The whole battle, from the Carthaginian standpoint, is a consummate piece of art, having no superior, few equal, examples in the history of war.^[53]

As Will Durant wrote, "It was a supreme example of generalship, never bettered in history... and it set the lines of military tactics for 2,000 years".^[54]

Hannibal's double envelopement at the Battle of Cannae is often viewed as one of the greatest battlefield manoeuvers in history, and is cited as the first successful use of the pincer movement within the Western world, to be recorded in detail.^[55]

The "Cannae Model"[link]

Apart from being one of the greatest defeats ever inflicted on Roman arms, the Battle of Cannae represents the archetypal battle of annihilation, a strategy that has rarely been successfully implemented in modern history. As Dwight D. Eisenhower, the Supreme Commander of the Allied Expeditionary Force in World War II, once wrote, "Every ground commander seeks the battle of annihilation; so far as conditions permit, he tries to duplicate in modern war the classic example of Cannae". Furthermore, the totality of Hannibal's victory has made the name "Cannae" a byword for military success, and is today studied in detail in several military academies around the world. The notion that an entire army could be encircled and annihilated within a single stroke, led to a fascination among subsequent Western generals for centuries (including Frederick the Great and Helmuth von Moltke) who attempted to emulate its tactical paradigm of envelopment and re-create their own "Cannae".^[29] Hans Delbrück's seminal study of the battle had a profound influence on subsequent German military theorists, in particular, the Chief of the German General Staff, Alfred von Schlieffen (whose eponymously titled "Schlieffen Plan" was inspired by Hannibal's double envelopment manoeuver). Through his writings, Schlieffen taught that the "Cannae model" would continue to be applicable in maneuver warfare throughout the 20th century:

A battle of annihilation can be carried out today according to the same plan devised by Hannibal in long forgotten times. The enemy front is not the goal of the principal attack. The mass of the troops and the reserves should not be concentrated against the enemy front; the essential is that the flanks be crushed. The wings should not be sought at the advanced points of the front but rather along the entire depth and extension of the enemy formation. The annihilation is completed through an attack against the enemy's rear... To bring about a decisive and annihilating victory requires an attack against the front and against one or both flanks...

Schlieffen later developed his own operational doctrine in a series of articles, many of which were later translated and published in a work entitled Cannae.

Historical sources[link]

The battle of Cannae (medieval representation).

There are three main accounts of the battle, none of them contemporary. The closest is Polybius, who wrote his account 50 years after the battle. Livy wrote in the time of Augustus, and Appian later still. Appian's account describes events that have no relation with those of Livy and Polybius.^[56] Polybius portrays the battle as the ultimate nadir of Roman fortunes, functioning as a literary device such that the subsequent Roman recovery is more dramatic. For example, some argue that his casualty figures are exaggerated—"more symbolic than factual".^[57] Livy portrays the Senate in the role of hero and hence assigns blame for the Roman defeat to the low-born Varro. Blaming Varro also serves to lift blame from the Roman soldiers, whom Livy has a tendency to idealize.^[58] Scholars tend to discount Appian's account. The verdict of Philip Sabin—"a worthless farrago"—is typical.^[59]

Historian Martin Samuels has questioned whether it was in fact Varro in command on the day on the grounds that Paullus may have been in command on the right. The warm reception that Varro received after the battle from the Senate was in striking contrast to the savage criticism meted out to other commanders. Samuels doubts whether Varro would have been received with such warmth had he been in command.^[60] Gregory Daly notes that, in the Roman military, the right was always the place of command. He suggests that at the Battle of Zama Hannibal was quoted saying that he had fought Paullus at Cannae and concludes that it is impossible to be sure who was in command on the day.^[61]

Cannae (mod. Canne della Battaglia) is an ancient village of the Apulia region of south east Italy. It is a frazione of the comune of Barletta.

Geography[link]

It is situated near the river Aufidus (the modern Ofanto), on a hill on the right (i.e., south) bank, 9.6 kilometers (6 mi) southwest from its mouth, and 9 km southwest from Barletta.

History[link]

It is primarily known for the Battle of Cannae, in which the numerically superior Roman army suffered a disastrous defeat by Hannibal in 216 BC (see Punic Wars). There is a considerable controversy as to whether the battle took place on the right or the left bank of the river.

In later times the place became a municipium, and remains of an unimportant Roman town still exist upon the hill known as Monte di Canne. In the Middle Ages it became a bishopric, and again saw military action in the second battle of Cannae, twelve centuries after the more famous one (1018). The town was destroyed in 1083 by Robert Guiscard, who left only the cathedral and bishop's residence,^[1] and was ultimately destroyed in 1276. Saint Roger of Cannae, (c. 1060 - 1138), was the most notable of the bishops.
