The Battle of Carrhae was fought in 53 BC between the Roman Republic and the Parthian Empire near the town of Carrhae. The Parthian Spahbod ("General") Surena the Iranian decisively defeated a numerically superior Roman invasion force under the command of Marcus Licinius Crassus. It is commonly seen as one of the earliest and most important battles between the Roman and Parthian empires and one of the most crushing defeats in Roman history.

Crassus, a member of the First Triumvirate and the wealthiest man in Rome, had been enticed by the prospect of military glory and riches and decided to invade Parthia without the official consent of the Senate. Rejecting an offer from the Armenian King Artavasdes II to allow Crassus to invade Parthia via Armenia, Crassus marched his army directly through the deserts of Mesopotamia. His army clashed with Surena's force near Carrhae, a small town in modern-day Turkey. Despite being heavily outnumbered, Surena's cavalry completely outmaneuvered the Roman heavy infantry, killing or capturing most of the Roman soldiers. Crassus himself was killed when truce negotiations turned violent. His death is sometimes associated with the end of the First Triumvirate, however Roman historians state that friction between Crassus and Pompey had always been a greater cause of tension than friction between Julius Caesar and Pompey. The four-year period after Carrhae, to the outbreak of the civil war between Julius and Pompey, argues against Crassus as a peace-keeper.

The war in Parthia resulted from political arrangements intended to be mutually beneficial for Crassus, Pompeius Magnus, and Julius Caesar — the so-called First Triumvirate. In March and April 56 BC, meetings were held at Ravenna and Luca, in Caesar's province of Cisalpine Gaul, to reaffirm the weakening alliance formed four years earlier. It was agreed that the triumvirate would marshal their supporters and resources to secure legislation for prolonging Caesar's Gallic command and to influence the upcoming elections for 55 BC, with the objective of a second joint consulship for Crassus and Pompeius.[3] The leaders of the triumvirate aimed to expand their faction's power through traditional means: military commands, placing political allies in office, and advancing legislation to promote their interests. Pressure in various forms was brought to bear on the elections: money, influence through patronage and friendship, and the force of a thousand troopers brought from Gaul by Crassus's son Publius. The faction secured the consulship and most, though not all, of the other offices sought. Legislation passed by the tribune Trebonius (the lex Trebonia) granted extended proconsulships of five years, matching that of Caesar in Gaul, to the two outgoing consuls. The Spanish provinces would go to Pompeius; Crassus arranged to have Syria, with the transparent intention of going to war with Parthia.[4]

The notoriously wealthy Marcus Crassus was around sixty and hearing-impaired[5] when he embarked on the Parthian invasion. Greed is often regarded by the ancient sources, particularly his biographer Plutarch, as his major character fault and also his motive for going to war.[6] Historian of Rome Erich Gruen believed that Crassus's purpose was to enrich the public treasury, since personal wealth was not what Crassus himself most lacked.[7] Most modern historians tend to view insatiable greed, envy of Pompey's military exploits, and rivalry as his motivation, since Crassus’s long-faded military reputation had always been inferior to that of Pompeius - and after five years of war in Gaul, to that of Caesar. His major military achievements had been the defeat of Spartacus in 71 and his victory at Battle of the Colline Gate for Sulla a decade earlier.[8] Plutarch notes that Caesar wrote to Crassus from Gaul, endorsing the plan to invade Parthia — an indication that he regarded Crassus's military campaign as complementary and not merely rivalrous to his own.[9] Another factor in Crassus's decision to invade Parthia was the expected ease of the campaign. The Roman legions had easily crushed the numerically superior armies of other eastern powers such as Pontus and Armenia, and Crassus expected Parthia to be an easy target.[10]

Cicero, however, suggests an additional factor: the ambitions of the talented Publius Crassus, who had commanded successful campaigns in Gaul under Caesar. Upon his return to Rome as a highly decorated officer, Publius took steps to establish his own political career. Roman sources view the Battle of Carrhae not only as a calamity for Rome and a disgrace for Marcus Crassus, but also as a tragedy for cutting short Publius Crassus's promising career.[11]

Some Romans objected to the war against Parthia. Cicero calls it a war nulla causa (“with no justification”), on the grounds that Parthia had a treaty with Rome.[12] The tribune Ateius Capito put up strenuous opposition, and infamously conducted a public ritual of execration as Crassus prepared to depart.[13]

Despite protests and dire omens, Marcus Crassus left Rome on November 14, 55 BC.[14] Publius Crassus joined him in Syria during the winter of 54–53 BC, bringing with him the thousand Celtic cavalry troopers from Gaul who remained loyal to their young leader until death.

Invasion of Parthia

Crassus arrived in Syria in late 55 BC and immediately set about using his immense wealth to raise an army. He assembled a force of seven legions (about 35,000 heavy infantry). In addition he had about 4,000 light infantry, and 4,000 cavalry, including the 1,000 Gallic cavalry Publius had brought with him.[15] With the aid of Hellenic settlements in Syria and support of about 6,000 cavalry from Artavasdes, the Armenian king, Crassus marched on Parthia. Artavasdes advised him to take a route through Armenia to avoid the desert and offered him reinforcements of 16,000 cavalry and 30,000 infantry.[16] Crassus refused the offer and decided to take the direct route through Mesopotamia, and capture the great cities in the region. In response, the Parthian king Orodes II divided his army and he took most of the soldiers, mainly foot archers with a small amount of cavalry, to punish the Armenians and sent the rest of his forces, 9,000 horse archers and 1,000 cataphracts under the command of the general Surena, to scout out and harass Crassus' army. Orodes did not anticipate that Surena's force, outnumbered by almost four to one, would be able to defeat Crassus, and merely wanted to delay him.

However, the fall of the Roman Republic intervened, and the beginning of imperial monarchy at Rome followed. Sulla's first march on Rome in 88 BC had begun the collapse of the republican form of government, but the death of Crassus and the loss of his legions utterly reconfigured the balance of power at Rome.[37] An old theory ran that the death of Crassus, along with the death of Julia in 54, Pompey's wife and Caesar's daughter, may have severed the ties between Caesar and Pompey; the first Triumvirate no longer existed. As a result, civil war broke out. Caesar won, and the Republic quickly became an autocratic dictatorship. But several astute historians note the lapse of time between Crassus' death and the outbreak of civil war. Gaius Stern has claimed that Crassus' death nearly cut the links the First Triumvirate enjoyed with the blue-blooded aristocracy, leaving the entire state vulnerable to the friction that eventually turned into civil war.[38] Thus, an immediate effect of the battle may have been the elimination of certain private checks and balances (e.g. Crassus' relationship to Metellus Pius Scipio) that formerly kept a lid on political tensions.

The capture of the golden aquilae (legionary battle standards) by the Parthians was considered a grave moral defeat and evil omen for the Romans. At the time of his assassination, Caesar was planning a retaliatory war. The Parthians are said to have feared especially harsh retribution if Caesar won, because the surviving son of Crassus would be among the Roman forces.[36]


Parthian Horseman

Gaius Cassius Longinus, a quaestor under Crassus, led approximately 10,000 surviving soldiers from the battlefield back to Syria, where he governed as a proquaestor for two years, defending Syria from Orodes II's further attacks. He received praise from Cicero for his victory. Cassius later played a key role in the conspiracy to assassinate Julius Caesar in 44 BC.

Rome was humiliated by this defeat, and this was made even worse by the fact that the Parthians had captured several Legionary Eagles.[33] It is also mentioned by Plutarch that the Parthians found the Roman prisoner of war that resembled Crassus the most, dressed him as a woman and paraded him through Parthia for all to see.[34] Orodes II, with the rest of the Parthian Army, defeated the Armenians and captured their country. However, Surena's victory invoked the jealousy of the Parthian king, and he ordered Surena's execution. Following Surena's death, Orodes II himself took command of the Parthian army and led an unsuccessful military campaign into Syria. The Battle of Carrhae was one of the first major battles between the Romans and Parthians. This battle also created the myth that Rome's legions could not combat the Parthian army. This myth was not dispelled even when the Parthian capital was sacked several times and after the several defeats that Roman armies inflicted to the Parthian ones. It was this belief that led Parthia to invade Syria and Armenia several times, with varying successes. Rome also realized that their legionaries could not effectively fight against Parthian cavalry.[35]

The next day, Surena sent a message to the Romans, offering to negotiate with Crassus. Surena proposed a truce, allowing the Roman army to return to Syria safely in exchange for Rome giving up all territory east of the Euphrates. Surena either sent an embassy to the Romans by the hills or went himself stating he wanted a peace conference to evacuate.[28][29] Crassus was reluctant to meet with the Parthians, but his troops threatened to mutiny if he did not.[30] At the meeting, a Parthian pulled at Crassus' reins, sparking violence. Crassus and his generals were killed. After his death, the Parthians allegedly poured molten gold down his throat, in a symbolic gesture mocking Crassus' renowned greed.[31] The remaining Romans at Carrhae attempted to flee, but most were captured or killed. Roman casualties amounted to about 20,000 killed and 10,000 captured[32] making the battle one of the costliest defeats in Roman history. Parthian casualties were minimal.

Crassus now hoped that his legionaries could hold out until the Parthians ran out of arrows.[25] However, Surena used thousands of Carrhae, leaving behind thousands of wounded, who were captured by the Parthians.[27]

The Parthians went to great lengths to intimidate the Romans. First they beat a great number of hollow drums and the Roman troops were unsettled by the loud and cacophonous noise. Surena then ordered his cataphracts to cover their armor in cloths and advance. When they were within sight of the Romans, they simultaneously dropped the cloths, revealing their shining armor. The sight was designed to intimidate the Romans, but Surena was impressed by the lack of effect it had.[21] Though he had originally planned to shatter the Roman lines with a charge by his cataphracts, he judged that this would not be enough to break them at this point. Thus, he sent his horse archers to surround the Roman square. Crassus sent his skirmishers to drive the horse archers off, but they were driven back by the latter's arrows. The horse archers then engaged the legionaries. The legionaries were protected by their large shields (scuta) and armor (reenactment with composite bows do not answer the question whether arrows can penetrate mail), but these could not cover the entire body. Some historians describe the arrows partially penetrating the Roman shields, and nailing the shields to the limbs of the Roman infantry. Other historians state that the majority of wounds inflicted were nonfatal hits to exposed limbs.[22] The Romans repeatedly advanced towards the Parthians to attempt to engage in close-quarters fighting, but the horse archers were always able to retreat safely, loosing Parthian shots as they withdrew. The legionaries then formed the testudo formation, in which they locked their shields together to present a nearly impenetrable front to missiles.[23] However, this formation severely restricted their ability in melee combat. The Parthian cataphracts exploited this weakness and repeatedly charged the Roman line, causing panic and inflicting heavy casualties.[24] When the Romans tried to loosen up their formation in order to repel the cataphracts, the latter rapidly retreated and the horse archers resumed shooting at the now more exposed legionnaires.[23]

After being informed of the presence of the Parthian army, Crassus panicked. His general Cassius recommended that the army be deployed in the traditional Roman fashion, with infantry forming the center and cavalry on the wings. At first Crassus agreed, but he soon changed his mind and redeployed his men into a hollow square, each side formed by twelve cohorts.[19] This formation would protect his forces from being outflanked, but at the cost of mobility. The Roman forces advanced and came to a stream. Crassus' generals advised him to make camp, and attack the next morning in order to give his men a chance to rest. Publius, however, was eager to fight and managed to convince Crassus to confront the Parthians immediately.[20]
