In 281 BC, the Greek city of Tarentum in southern Italy faced an increasingly powerful enemy.
Rome.
Desperate for military assistance, the Tarentines appealed across the Adriatic to Pyrrhus, king of Epirus, one of the most ambitious commanders of the Hellenistic world.
Pyrrhus accepted.
He had grown up in the violent political world created by the successors of Alexander the Great, and ancient writers remembered him as an exceptionally talented commander. Plutarch even reports that Hannibal later ranked Pyrrhus among history's greatest generals, although versions of the famous ranking differ.
In 280 BC, Pyrrhus crossed into Italy with a formidable Hellenistic army.
Ancient accounts give varying numbers, but Plutarch describes roughly 20,000 infantry, 3,000 cavalry, 2,000 archers, 500 slingers—and 20 elephants.
Rome was about to encounter an enemy unlike anything it had previously fought.
At the Battle of Heraclea, Roman legions collided with Pyrrhus's forces.
The fighting was fierce. Ancient accounts describe repeated advances and reversals before Pyrrhus committed his most terrifying weapon:
war elephants.
The Romans had little experience confronting them.
The enormous animals disrupted Roman cavalry and contributed to the collapse of the Roman position. Pyrrhus won the battle.
But victory revealed Rome's greatest weapon.
It wasn't a sword.
It wasn't a formation.
It was manpower.
Pyrrhus's experienced troops were difficult to replace. Rome, by contrast, possessed a deep reservoir of Roman citizens and Italian allies from which new armies could be raised.
Pyrrhus had defeated a Roman army.
He had not defeated Rome's ability to create another one.
The following year, the armies met again at Asculum.
Ancient accounts disagree about important details, including exactly how the fighting unfolded and the casualties suffered. Plutarch describes a battle lasting two days and again gives Pyrrhus the victory.
But it was another horribly expensive success.
Plutarch says Pyrrhus lost 3,505 men. Other ancient traditions provide very different figures, which is why precise casualty totals should be treated cautiously.
More damaging than the raw number was the quality of the men he had lost.
According to Plutarch, many of Pyrrhus's officers and best soldiers were dead.
Rome could replenish its armies.
Pyrrhus increasingly could not.
Then came the remark that transformed his name into a phrase still used more than 2,000 years later.
When someone congratulated him on defeating the Romans, Plutarch says Pyrrhus replied, in effect:
“If we are victorious in one more battle with the Romans, we shall be utterly ruined.”
From that story comes the expression:
PYRRHIC VICTORY.
A victory purchased at such enormous cost that winning becomes almost indistinguishable from losing.
Pyrrhus would continue fighting. He went to Sicily, returned to Italy, and eventually faced Rome again at Beneventum in 275 BC, after which he withdrew from Italy.
Rome survived.
Tarentum eventually fell.
And Pyrrhus left behind something more enduring than the Italian kingdom he had hoped to build.
He left his name attached to one of history's cruelest paradoxes:
You can win every battle that matters—and still lose because you cannot afford the price of victory. See less
