The Battle of Cannae was a major battle of the Second Punic War, taking place on August 2, 216 BC near the town of Cannae in Apulia in southeast Italy. The Carthaginian army under Hannibal destroyed a numerically superior Roman army under command of the consuls Lucius Aemilius Paullus and Gaius Terentius Varro. Following the Battle of Cannae, Capua and several other Italian city-states defected from the Roman Republic. Although the battle failed to decide the outcome of the war in favour of Carthage, it is today regarded as one of the greatest tactical feats in military history.
Having recovered from their previous losses at Trebia (218 BC) and Trasimene (217 BC), the Romans decided to confront Hannibal at Cannae, with roughly 87,000 Roman and Allied troops. With their right wing positioned near the Aufidus river, the Romans placed their cavalry on their flanks and massed their heavy infantry in an exceptionally deep formation in the centre. To counter this, Hannibal utilized the double-envelopment tactic. He drew up his least reliable infantry in the centre, with the flanks composed of Carthaginian cavalry. Before engaging the Romans, however, his lines adopted a crescent shape —advancing his centre with his veteran troops placed at the wings in echelon formation. Upon the onset of the battle, the Carthaginian centre withdrew before the advance of the numerically superior Romans. While Hannibal's centre line yielded, the Romans had unknowingly driven themselves into a large arc —whereupon the Carthaginian infantry and cavalry (positioned on the flanks) encircled the main body of Roman infantry. Surrounded and attacked on all sides with no means of escape, the Roman army was subsequently cut to pieces. An estimated 60,000 —70,000 Romans were killed or captured at Cannae (including the consul Lucius Aemilius Paullus and eighty Roman senators). In terms of the number of lives lost within a single day, Cannae is among the costliest battles in all of recorded human history.
Unimpressed with Fabian's strategy, the Roman Senate did not renew his dictatorial powers at the end of his term, and command was given back to the consuls Gnaeus Servilius Geminus and Gaius Flaminius. In 216 BC elections resumed with Caius Terentius Varro and Lucius Aemilius Paullus elected as consuls and given command of a newly raised army of unprecedented size in order to counter Hannibal. Polybius writes:
These eight legions, 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 an additional 4,000 allied cavalry, the total strength of the army which faced Hannibal could not have been much less than 90,000.Cottrell, Leonard, Enemy of Rome, Evans Bros, 1965, ISBN 0237443201 (pbk) Some estimates place the Roman forces at about 100,000 men, although historical evidence for such a large force is questionable.
Consul Varro, who was in command on the first day, was 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 had 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 confidence in the Roman army, perhaps to over-confidence 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 and sent 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. Cottrell, Leonard, Enemy of Rome, Evans Bros, 1965, ISBN 0237443201 (pbk)
The two armies stayed in their respective locations for two days. During the second of these two days (August 1), Hannibal, well 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 Polybius, The Histories of Polybius, 2 Vols., trans. Evelyn S. Shuckburgh (London: Macmillan, 1889), I. 264-275. read at Internet Ancient History Sourcebook, 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 campCaven, B., Punic Wars, London, George Werdenfeld and Nicholson Ltd., 1980. Enraged by this foray, Varro assumed command on August 2, marshaled his forces, and crossed back over the Aufidus to do battle.
To Varro, Hannibal seemed to have little room to maneuver 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 maneuver, would be cut down in panic. Bearing in mind the fact 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.
Hannibal, on the other hand, had deployed his forces based on the particular fighting qualities of each unit, taking into considertion both their strengths and weaknesses in devising his strategy . He placed his lowest quality infantry (Iberians, Gauls and Celts) in the middle, and his better infantry (Libyan-Phoenician mercenaries) either just inside or behind his cavalry on the wings. He intended that his cavalry, positioned on the flanks, 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 African troops would then press in from the flanks at the crucial moment, and encircle the overextended Roman army.
Hannibal was unconcerned 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 larger, more numerous Romans. Furthermore, because the Romans were in front of the hill leading to Cannae and hemmed in on their right flank by the Aufidus River, their left flank was the only viable means of retreatBradford, E., Hannibal, London, Macmillan London Ltd, 1981. In addition, the Carthaginian forces had maneuvered so that the Romans would face east, while they would face west. Not only would the morning sunlight shine on the Romans, but the southeasterly winds would blow sand and dust into the faces of the Romans as they approached the battlefieldDodge, Theodore, Hannibal, Cambridge, Massachusetts, De Capo Press, 1891, ISBN 0306813629. It was Hannibal’s unique deployment of his army based on his perception and understanding of the capabilities of his troops, that would prove to be the defining factors in his victory at Cannae.
When the battle was joined, the cavalry engaged in a fierce exchange on the flanks. Polybius describes the scene Polybius, The Histories of Polybius, 2 Vols., trans. Evelyn S. Shuckburgh (London: Macmillan, 1889), I. 264-275. read at Internet Ancient History Sourcebook, writing that "When the Spanish and Celtic Horse on the left wing came into collision with the Roman cavalry, the struggle that ensued was truly barbaric.". Here, the Carthaginian cavalry quickly overpowered the inferior Romans on the right flank and routed them. A portion of the Carthaginian cavalry then detached itself from the Carthaginian left flank and made a wide circling pivot to the Roman right-flank, where it fell upon the rear of the Roman cavalry. The Roman cavalry was immediately dispersed as the Carthaginians fell upon them and began "cutting them down mercilessly".
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 west wind 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. This, combined with the lack of proper hydration due to Hannibal's attack on the Roman encampment during the previous day, would have affected the individual performance of the Roman troops.
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 forward, the bulk of the Roman troops began to lose their cohesion, as they began crowding themselves into the growing gap. Soon they were so compact together that they had little space to wield their weapons. In passing so far forward in their desire to destroy the retreating and collapsing line of Hispanic and Gallic troops, the Romans had ignored the African troops that stood uncommitted on the projecting ends of this now reversed-crescentHealy, Mark, Cannae: Hannibal Smashes Rome's Army, Sterling Heights, Missouri, Osprey Publishing, 1994. 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 at the echelons. 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 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 decimating 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 lying... 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.". Nearly six hundred legionaries were slaughtered each minute until darkness brought an end to the bloodletting Cowley, Robert (ed.), Parker, Geoffrey (ed.), The Reader’s Companion to Military History, "Battle of Cannae", Houghton Mifflin Company, 1996, ISBN 0-395-66969-3. Only 14,000 Roman troops managed to escape (most of whom had cut their way through to the nearby town of Canusium). At the end of the day, out of the original force of 87,000 Roman troops, only about one out of every ten men was still alive.
If true, this makes the Battle of Cannae one of the single bloodiest battles in all of recorded human history, in terms of the number of lives lost within a day. The total number of lives lost surpasses the number of servicemen killed in the Royal Air Force throughout the First and Second World Wars. More men were killed at Cannae than in all the four months of the Battle of Passchendaele, which is considered one of the bloodiest battles of World War One. So devastating were these losses, that the total number of casualties represents just under one third of the total number of American soldiers, sailors, and airmen killed in four years of fighting during the Second World War In fact, the losses suffered within a single day on the battlefield of Cannae (no larger than a few square miles), would not be equaled until the first day of fighting on the Somme in 1916 —which took place on a 25-mile front over 2,000 years laterGoldsworthy, A, The Punic Wars, London, Cassell and Company, 2000.
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 a complete 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 knew a person who had died. The Romans became so desperate that they resorted to human sacrifice, killing a few slaves and burying them in the forum of Rome (perhaps one of the last recorded instances of human sacrifices the Romans would perform).
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. 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 loss. In addition to the physical loss of her army, Rome would suffer a symbolic defeat, one that was severely humiliating to her prestige. 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; this collection was poured on the floor in front of the Carthaginian Senate, and was judged to be "three and a half measures". A gold ring was a token of membership in the upper classes of Roman society.
Hannibal, having gained yet another victory (following the battles of Trebia and Lake Trasimene), had defeated the equivalent of eight consular armies . Within just three campaign seasons, Rome had lost a fifth of the entire population of citizens over seventeen years of age (nearly twelve percent of Rome’s available manpower). 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 Polybius 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." Polybius, The Histories of Polybius, 2 Vols., trans. Evelyn S. Shuckburgh (London: Macmillan, 1889), I. 264-275. read at Internet Ancient History Sourcebook 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 most significant city in Sicily.
Following the battle, Hannibal's officers wanted to march on Rome. Yet despite the tremendous material loss inflicted on the Romans, the defection of many allied cities, and the declaration of war by Philip and Hieronymus, Hannibal, lacking any siege equipment or the appropriate resources, refused to do so. This was much to the distress of Maharbal, one of his cavalry commanders, who is famously quoted as saying, "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.". Instead, Hannibal offered 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 simply re-doubled their efforts, declaring full mobilization of the male populations, while raising new legions recruited from landless peasants and even slaves. So firm were these measures, that the word “peace” was prohibited, mourning limited to only thirty days, and public tears restricted to women Dodge, Theodore, Hannibal, Cambridge, Massachusetts, De Capo Press, 1891, ISBN 0306813629Cottrell, Leonard, Enemy of Rome, Evans Bros, 1965, ISBN 0237443201 (pbk). 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 no longer engage in pitched battles against Hannibal. Rather, they utilized the strategies Fabius had taught them, and which, they finally realized, were the only feasible means of driving Hannibal from Italy.
In addition, the necessity of a unified command was finally recognized. 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, "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 molded into a superb fighting force.
Hannibal's double envelopement at the Battle of Cannae is often viewed as one of the greatest battlefield maneuvers in history, and is cited as the first successful use of the pincer movement within the Western world, to be recorded in detail .
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 Graf von Schlieffen (whose eponymously-titled "Schlieffen Plan" was inspired by Hannibal's double envelopment maneuver). Through his writings, Schlieffen taught that the "Cannae model" would continue to be applicable in maneuver warfare throughout the twentieth 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".
