The Battle of Asculum was a poorly documented battle that took place near Asculum (modern Ascoli Satriano) in 279 BC, and was thought to have lasted either one or two days, between the Roman Republic under the command of the consuls Publius Decius Mus (who by some accounts died before the battle) and Publius Sulpicius Saverrio, and the forces of King Pyrrhus of Epirus. The battle took place during the Pyrrhic War, after the Battle of Heraclea of 280 BC, which was the first battle of the war. There currently exist accounts of this battle only by three ancient historians: Dionysius of Halicarnassus, Plutarch, and Cassius Dio, although these historians in turn reference other historians whose work is now lost. Asculum was in Lucanian territory, in southern Italy. The Battle of Asculum was the original "Pyrrhic victory". Two main accounts of the battle survive. Plutarch describes a two-day battle where Pyrrhus attacked the Romans on the first day over rough terrain before on the second day Pyrrhus secured flat terrain which allowed his elephantry and cavalry to defeat the Romans. Dionysius of Halicarnassus, followed by Dio and Zonaras, instead presents a single-day battle in which Roman forces break through the Epirote centre, producing an inconclusive engagement that ended in the night. Plutarch's narrative however is the more reliable. A third variant tradition, rather than marking a Epirote victory or indecision, instead reports that the Romans won; the historian Patrick Kent dismisses these claims as products of patriotic Roman historiography, attributing them to the poet Ennius and later Roman historians' biases. Jeff Champion suggests that it was a narrow tactical victory to Pyrrhus.
