The Battle of HeracleaPyrrhus marched to Heraclea and made his fortified camp*, there he witnessed for the first time the Drill and order of the Romans. It was quite a shock to him to realize that not only was his opposition more numerous, but it was also a cut above the “barbarian” forces he expected to face!
At least he felt confident that the Roman swordsmen would be at a disadvantage versus the phalanx, his superior cavalry, and his “Trump” card, the elephants. He reckoned that these factors would be enough to outweigh the Romans numerical advantage. Nevertheless, Pyrrhus deployed his forces behind the river Siris, smartly working the terrain to his advantage. Pickets and light troops covered the stream and the elephants were wisely kept behind the phalanx in reserve.
(*Apparently the Romans were so impressed with Pyrrhus’s walled camp that they copied it! Pyrrhus no doubt was well inclined to go to this unusual measure because of the tricks he learned from his first benefactor, Antigonus 1
st.)
The Romans for their part were unusually aggressive and spirited as they believed that they would deal with Pyrrhus’s army with the same ease that they had previously handled the Tarentine levies. Laevinius ordered out the Legions and they advanced on the Epirote pickets. The Roman and Allied cavalry were sent up and down stream and forded the river. The Epirote pickets along the stream fell back as their flanks were turned.
The Roman cavalry attempted to pursue and Pyrrhus saw his first opportunity to counterstrike. He charged the Roman and Allied horsemen with his Agema cavalry with his Thessalians in reserve. They were turned back by the Italian horse and soon this action turned into a stalemate in which Pyrrhus’ outnumbered horsemen just could barely hold their own. Soon, almost all of Pyrrhus’ horsemen were thrown into this cavalry battle. Pyrrhus joined the melee, inspiring his troops and overawing his opponents. At this time a Italian cavalry officer charged Pyrrhus and unhorsed him. Pyrrhus was luckily saved by his retainers and he decided to take off his conspicuous armor and gave it to his Commander Megacles. Megacles rejoined the fight and the Epirote cavalry held.
Pyrrhus, unhorsed and bruised, made his way back to the main battle line.
The Romans were busily crossing the Siris river and Pyrrhus launched the phalanx at their leading maniples. A severe struggle ensued as the Pikemen suffered the hail of Pila and then pressed forward against the Hastati. The Romans for their part were stymied by the serried ranks of pikemen and could make little impression upon them. Individual Legionnaires attempted to roll under the pikes and break up the phalanx’s but these “forlorn hopes” were cut down. Hacking at the spear points was also a desperate measure attempted with little success. The Maniples were unable to stop the Phalanx. The Hastati line was decimated and fell back and the Principes took on the struggle. A series of clashes occurred with charges and counter charges delivered by both sides. The Romans were frustrated because they couldn’t break through the wall of pikes, the Epirotes and Macedonians were frustrated because every time they defeated a maniple they couldn’t pursue, another maniple would threaten to flank them if they opened a gap in their line. These were seasoned phalangites and they were savvy enough to know that they could not offer these compact maniple formations a chance to penetrate their line. Seven times the phalangites clashed with the maniples as they charged, pulled back and were replaced by reserve maniples.
Luckily for Pyrrhus the river crossing apparently had funneled the Roman advance and somehow the Allied Legions were unable to deploy on a wide enough front to flank the Epirote battleline. Neither the Tarentines or the Allied Legions are mentioned and may have cancelled each other out.
As stalemate seemed to be spread across the battleline, a Roman officer killed Megacles and carried Pyrrhus’ goat horned helmet and cloak to Laevinius shouting to all that Pyrrhus was dead! The Romans, at their lowest ebb, were rejuvenated, and the Epirotes wavered and fell back. Pyrrhus took off his helmet and rode in front of the lines to show his troops the ruse. This dramatic display saved his army and they stood their ground once again.
During this confusion, Laevinius threw in his reserve of Roman cavalry against the phalanx’s exposed flank. Pyrrhus saw this as the decisive moment and gathered his elephants. As the Romans attempted to charge the phalanx they were in turn charged by the elephants. The Roman horses could not stand up to the “Lucanian Oxen” as they called them, and they fled through the Legions. The elephants spread panic and terror before them and the Legions broke. Pyrrhus launched a vigorous pursuit with his Thessalian cavalry. The Roman army could have been annihilated with it’s back to the stream, but the first Hastate of the Fourth Legion, Gaius Minucius, wounded Pyrrhus’ leading elephant which bolted back through the Epirote phalanx. The phalanx halted and the Romans melted away in confusion and rout.
The battle was a “Near Run thing” for Pyrrhus. It is stated that the Romans lost 7000 killed and carried away 6000 wounded, 2000 prisoners were taken. But unlike Alexander’s victories, Pyrrhus’ army suffered up to 4000 dead themselves, including his General Megacles and many of his closest Companions.
