Battle of Asculum

Battle context

The Battle of Asculum, fought near Asculum in Lucanian territory in 279 BC, was the second major engagement of the Pyrrhic War, following Pyrrhus's victory at Heraclea in 280 BC. Both sides committed forces of approximately 40,000, indicating the scale of effort each power brought to the contest. Pyrrhus's army suffered around 3,505 casualties against a Roman loss of roughly 6,000, a disparity that nominally favored the Epirotes but left Pyrrhus's expeditionary force — far from its home base and unable to easily replace losses — in a strategically weakened position. The battle is the origin of the phrase 'Pyrrhic victory,' reflecting the recognition, preserved in accounts by Dionysius of Halicarnassus, Plutarch, and Cassius Dio, that tactical success at such cost could not be sustained. With the result not recorded as a decisive Roman victory, the engagement nonetheless demonstrated the attritive pressure Rome could sustain through the Pyrrhic War against a professional Hellenistic army.
