), attempting to provoke each other into a battle on favorable terrain for several days.When the battle finally began, Eumenes managed to throw the Seleucid left flank into disarray. While Antiochus' cavalry overpowered his adversaries on the right flank of the battlefield, his army's center collapsed before he could reinforce it. Modern estimates give 10,000 dead for the Seleucids and 5,000 killed for the Romans. The battle resulted in a decisive Roman-Pergamene victory, which led to the Treaty of Apamea that ended Seleucid domination in Asia Minor.
Background
Following his return from his Bactrian (210-209 BC)
In late winter 196/195 BC, Rome's erstwhile chief enemy, Carthaginian general Hannibal, fled from Carthage to Antiochus' court in Ephesus. Despite the emergence of a pro-war party led by Scipio Africanus, the Roman Senate exercised restraint. The Seleucids expanded their holdings in Thrace from Perinthus to Maroneia at the expense of the Thracian tribesmen. Negotiations between the Romans and the Seleucids resumed, coming to a standstill once again over differences between Greek and Roman law on the status of disputed territorial possessions. In the summer of 193 BC, a representative of the Aetolian League assured Antiochus that the Aetolians would take his side in a future war with Rome, while Antiochus gave tacit support to Hannibal's plans of launching an anti-Roman coup d'état in Carthage.[6] The Aetolians began spurring the Greek states to jointly revolt under Antiochus' leadership against the Romans, hoping to provoke a war between the two parties. The Aetolians then captured the strategically important port city of Demetrias, killing the key members of the local pro-Roman faction. In September 192 BC, the Aetolian general Thoantas arrived at Antiochus' court, convincing him to openly oppose the Romans in Greece. The Seleucids raised 10,000 infantry, 500 cavalry, 6 war elephants, and 300 ships for their campaign in Greece.[7]
Prelude
The Seleucid fleet sailed via Imbros and Skiathos, arriving at Demetrias where Antiochus' army disembarked.[8] The Achaean League declared war on the Seleucids and Aetolians with the Romans following suit in November 192 BC. Antiochus forced Chalcis to open its gates to him, turning the city into his base of operations. Antiochus then shifted his attention towards rebuilding his alliance with Philip V of Macedon, which had been shattered after the latter was decisively defeated by the Romans at the Battle of Cynoscephalae in 197 BC. Philip expected that the Romans would emerge victorious in the conflict and counted on territorial rewards as well as the writing off of war reparations that he owed them; the Seleucids could provide neither, so Antiochus' overtures were rejected and Philip aligned himself with the Romans. Between December 192 and March 191 BC, Antiochus campaigned in Thessaly and Acarnania.[9]
A combined
Armies
The two main historical accounts of the battle come from
The left wing of the Seleucids was commanded by Antiochus' son
The left wing of the Romans was commanded by the legate Gnaeus Domitius Ahenobarbus. It numbered 10,800 heavy infantrymen drawn from among the Romans and Rome's Socii, along with four cavalry companies of 100 to 120 men. The center likewise consisted of 10,800 Roman and Latin heavy infantrymen commanded personally by Scipio. The Roman infantry was divided into three lines, with the youngest soldiers standing at the front, in a more open and flexible formation than their adversaries. The right flank was led by Eumenes and comprised 2,800 to 3,000 cavalry, the majority being Romans supplemented by an 800-man Pergamene force. Ahead of the Roman main force were 3,000 Achaean and Pergamene light infantry and 800 Cretan and Illyrian archers. The rearguard was formed by 2,000 Thracian and Macedonian volunteers and 16 African war elephants that were considered inferior to the Asian war elephants deployed by the Seleucids.[17][22][23]
Battle
The battle took place either in December 190 BC or January 189 BC.[13] The Romans advanced from Pergamon towards Thyatira where they expected to encounter Antiochus. Antiochus was determined to fight his adversaries on the ground of his own choosing, and his army marched from the direction of Sardis towards Magnesia ad Sipylum, camping 15 kilometres (9.3 mi) northeast of the city. Magnesia had already served as a battlefield for the Seleucids in 281 BC where they had emerged victorious in the Battle of Corupedium.[15] Upon learning that the Seleucids had left Thyatira, the Romans marched for five days towards the River Phrygios, camping north of the River Hermos,[24] 6.5 kilometres (4.0 mi) from the Seleucid camp. Antiochus dispatched a party of 1,000 Galatian and Dahae cavalry to lure the Romans into a more exposed position, but the Romans refused to be drawn out. Three days later,[17] the Romans moved their camp into a horseshoe-shaped plain some 4 kilometres (2.5 mi) from the Seleucid camp, which was surrounded by the Phrygios and Hermos rivers on three sides, by which the Romans hoped to limit the effectiveness of the Seleucid cavalry.[25] The Seleucids once again sent an elite 3,000-man detachment to harass the Romans.[17]
During the following five days, the two armies lined up for battle, without engaging each other. Scipio found himself in a zugzwang. He could not hope to win the battle by directly assaulting the heavily-fortified Seleucid camp, but by refusing to engage he risked having his supply lines cut by the numerically-superior enemy cavalry. Turning back would have caused Roman morale to plunge as campaigns were halted during the winter. Additionally, Scipio wished to achieve a decisive victory over the Seleucids before a new consul was sent out from Rome to replace him.[17] The Romans advanced to the point where the Phrygios made a 90-degree turn towards the north, leaving their right flank unprotected by the rivers.[25] Antiochus was satisfied with the location, accepting the Roman challenge on the dawn of the third day after the last Roman advance.[17]
The battle began on the Seleucid left flank when Eumenes sent forward his archers, slingers, and spearmen to harass the Seleucid scythed chariots. The latter began fleeing in panic after suffering heavy casualties, causing confusion among the camel-borne Arab archers and cataphracts positioned behind them. Eumenes then charged with his cavalry before the cataphracts could properly reorganize. The Roman and Pergamene cavalry broke through the Seleucid left flank, causing the cataphracts to flee to the Seleucid camp. The Galatians, Cappadocians, and mercenary infantry to the left of the phalanx faced a simultaneous attack from the Roman center and right, causing them to retreat and exposing the phalanx's left flank.[26][27]
On the Seleucid right flank, Antiochus led the attack with the cataphracts and agema cavalry facing the Latin infantry, while the argyraspides engaged the
Aftermath
Antiochus' defeat at Magnesia marked the end of the Macedonian phalanx's dominance on Hellenistic period battlefields.[31] According to Livy 53,000 Seleucid soldiers perished, with 1,400 being captured alongside 15 elephants. By comparison, Livy claims that the Romans lost 349 men with many more wounded. Modern estimates give 10,000 dead for the Seleucids and 5,000 killed for the Romans. Shortly after arriving at Sardes, Antiochus learnt that Seleucus had survived the battle and headed to Apamea to meet him.[32] The defeat at Magnesia and the subsequent withdrawal of the Seleucid fleet from Ephesus to Patara led the garrisons of numerous cities including Sardes, Ephesus, Thyatira, and Magnesia ad Sipylum to surrender to the Romans. Antiochus dispatched Zeuxis and Antipater to the Romans, in order to secure a truce. The truce was signed at Sardes in January 189 BC, whereupon Antiochus agreed to abandon his claims on all lands west of the Taurus Mountains, paid a heavy war indemnity and promised to hand over Hannibal and other notable enemies of Rome from among his allies.[33]
The Romans sought to subjugate Asia Minor and punish Antiochus' allies, starting the Galatian War. In mainland Greece they suppressed the Athamanians and Aetolians who broke the terms of a previous truce.[34] During the summer of 189 BC, ambassadors from the Seleucid Empire, Pergamon, Rhodes, and other Asia Minor states held peace talks with the Roman Senate. Lycia and Caria were given to Rhodes, while the Attalids received Thrace and most of Asia Minor west of the Taurus. The independence of Asia Minor city-states that sided with the Romans before the Battle of Magnesia was guaranteed. Antiochus further agreed to withdraw all his troops from beyond the Taurus, and refuse passage and support to enemies of Rome. The conditions also included the requirement to hand over Hannibal, Thoantas, and twenty notables as hostages, destroy all his fleet apart from ten ships, and give Rome 40,500 modiuses of grain per year. The terms were put into effect in the summer of 188 BC with the signing of the Treaty of Apamea.[35]
