On October 6, 69 BC, the Battle of Tigranocerta took place. When going into battle, some of Lucullus's men warned him it was one of Rome's "black days", the anniversary of the defeat of the Romans at the hands of the Cimbri. Lucullus replied that he would make it a lucky day. From the article:
"Tigranes, who was residing at Tigranocerta in the summer of 69, was not only astonished by the speed of Lucullus' rapid advance into Armenia but by the fact that he had even launched such an operation in the first place. Unable to reconcile with this reality for a certain period of time, he belatedly sent a general named Mithrobarzanes with 2,000 to 3,000 cavalrymen to slow down Lucullus' advance but his forces were cut to pieces and routed by the 1,600 cavalry led by Sextilius, one of the legates serving under Lucullus. Learning of Mithrobarzanes' defeat, Tigranes entrusted the defence of his namesake city to Mancaeus and left to recruit a fighting force in the Taurus Mountains.[5] Lucullus' legates were able to disrupt two separate detachments coming to the aid of Tigranes and even located and engaged the king's forces in a canyon in the Taurus. Lucullus chose not to pursue Tigranes while he had an unimpeded path towards Tigranocerta; he advanced and began to lay siege to it.[6]
Tigranocerta was still an unfinished city when Lucullus laid siege to it in the late summer of 69. The city was heavily fortified and according to the Greek historian Appian, had thick and towering walls that stood 25 meters high, providing a formidable defence against a prolonged siege.[7] The Roman siege engines that were employed at Tigranocerta were effectively repelled by the defenders by the use of naphtha, making Tigranocerta, according to one scholar, the site of "perhaps the world's first use of chemical warfare."[8]
However, since Tigranes had forcibly removed many of its inhabitants from their native lands and brought them to Tigranocerta, their allegiance to the king was cast into doubt. They soon proved their unreliability: when Tigranes and his army appeared on a hill overlooking the city, the inhabitants "greeted his [Lucullus] appearance with shouts and din, and standing on the walls, threateningly pointed out the Armenians to the Romans."[9]
Forces Edit
Appian claims that Lucullus had embarked from Rome with only a single legion; upon entering Anatolia to make war against Mithridates, he added four more legions to his army. The overall size of this force consisted of 30,000 infantry and 1,600 cavalry.[10] Following Mithridates' retreat to Armenia, Appian estimates Lucullus' invading force to be only two legions and 500 horsemen,[11] although it is highly improbable that he would have undertaken the invasion of Armenia with such a small army.[12] Plutarch gave 16,000 heavy infantry and 1,000 cavalry, slingers and archers for the Romans at Tigranocerta. Of these, 6,000 heavy infantry did not participate in the battle.[13] Eutropius put the Roman army at 18,000 men.[14] Historian Adrian Sherwin-White places the size of Lucullus' force to 12,000 seasoned legionaries (composed of three legions), and 4,000 provincial cavalry and light infantry.[15] The Roman army was further bolstered by several thousand allied Gallic, Thracian, and Bithynian infantry and cavalry, giving it a possible strength of 40,000.[2]
Tigranes' army clearly held a numerical superiority over that of Lucullus'.[16] According to Appian, it numbered 250,000 infantry and 50,000 cavalry.[17] According to Plutarch, Lucullus stated in a letter to the senate to have fought 20,000 slingers and archers, 55,000 cavalry, including 17,000 armoured with mail, 150,000 heavy infantry and 35,000 non-combatants for a total of 225,000 soldiers and 35,000 non-combatants.[18] Eutropius went further, claiming 600,000 Armenian cataphracts and 100,000 infantry.[19] Memnon of Rhodes gave a more modest 80,000 infantry and cavalry.[20] Phlegon of Tralles says Tigranes had 70,000 men, including 30,000 cavalry and 40,000 infantry.[21] Many scholars, however, doubt these figures accurately reflect the true number of Tigranes' army and believe they are highly inflated.[12][22] Some historians, most notably Plutarch, wrote that Tigranes considered Lucullus' army far too small, and upon seeing it, is quoted to have said that "If they come as ambassadors, they are too many; if they are soldiers, too few,"[23] although some have expressed doubt on the veracity of this quote.[24][25] In 1985, Ruben Manaseryan estimated Tigranes' army at 80,000–100,000 men.[2] Tigranes also possessed several thousand cataphracts, formidable heavily armoured cavalry that were clad in mail armour and armed with lances, spears or bows.[26]
Disposition and engagement Edit
The commander of the Roman Senate army, Lucius Licinius Lucullus.
The two armies converged toward the Batman-Su river slightly to the south-west to Tigranocerta.[27]
Tigranes' army was positioned on the east bank of the river while Lucullus, who had left a rear guard of 6,000 heavy infantry under Murena to continue the siege of the city, met the Armenian army on the river's west bank.[28] The Armenian army was formed of three sections.[12] Two of Tigranes' vassal kings led the left and right flanks, while Tigranes led his cataphracts in the centre. The rest of his army stood in front of a hill, a position Lucullus soon exploited.[citation needed]
Roman troops at first attempted to dissuade Lucullus from engaging in battle since October 6 marked the day of the disastrous battle of Arausio, where the general Quintus Servilius Caepio and his Roman army were delivered a crushing defeat by the Germanic Cimbri and Teuton tribes. Ignoring his troops' superstitious beliefs, Lucullus is said to have responded, "Verily, I will make this day, too, a lucky one for the Romans."[29]
Cowan and Hook suggest that Lucullus would have deployed the Romans in a simplex acies, that is to say a single line, so making the frontage of the army as wide as possible as a counter to the cavalry.[22] He took several of his troops downriver, where the river was the easiest to ford, and at one moment, Tigranes believed that this move meant Lucullus was withdrawing from the battlefield.[30]
Lucullus had initially decided to make a running charge with his infantry, a Roman military tactic that minimized the amount of time an enemy could utilize its archers and sling infantry prior to close combat engagement.[31] However, he decided against this at the last moment when he realized that the Armenian cataphracts posed the greatest threat to his men, ordering instead a diversionary attack with his Gallic and Thracian cavalry against the cataphracts.[citation needed]
With the cataphracts' attention fixated elsewhere, Lucullus formed two cohorts into maniples and then ordered them to ford across the river.[32] His objective was to outflank Tigranes' cataphracts by circling counterclockwise around the hill and attacking them from the rear.[33]
Lucullus personally led the charge on foot and upon reaching the top of the hill, he yelled to his soldiers in an effort to buoy their morale: "The day is ours, the day is ours, my fellow soldiers!"[34] With this, he gave special instructions to the cohorts to attack the horses' legs and thighs, since these were the only areas of the cataphracts which were not armoured.[35][36] Lucullus charged downwards along with his cohorts and his orders soon proved decisive: the lumbering cataphracts were caught by surprise and, in their attempts to break free from their attackers, careened into the ranks of their own men as the lines began to collapse.[11][37]
The infantry, which was also made up of many non-Armenians, began to break rank and confusion spread to the rest of the body of Tigranes' army. While the great king himself took to flight with his baggage train northwards, the entire line of his army gave way.[citation needed]
Aftermath and legacy Edit
With no army left to defend Tigranocerta, and a foreign populace that gleefully opened the gates to the Romans, Lucullus' army began the wholesale looting and plunder of the city.[38] The city was burned. The king's treasury, estimated to be worth 8,000 talents,[39] was looted and each soldier in the army was awarded 800 drachma. The battle also resulted in severe territorial losses: most of the lands in Tigranes' empire to the south of the Taurus fell under the sway of Rome.[citation needed]
Despite the heavy losses Tigranes suffered, the battle did not end the war. In retreating northwards, Tigranes and Mithridates were able to elude Lucullus' forces, though losing again against the Romans during the battle of Artashat.[40] In 68, Lucullus' forces began to mutiny, longing to return home, and he withdrew them from Armenia the following year.[41]
The battle is highlighted by many historians specifically because Lucullus overcame the numerical odds facing his army.[12] The Italian philosopher Niccolò Machiavelli remarked upon the battle in his book, The Art of War, where he critiqued Tigranes' heavy reliance on his cavalry over his infantry."
