Plutarch gave the most detailed account of the battle. He wrote that during the three years Pyrrhus spent campaigning in Sicily the Samnites suffered many defeats at the hands of the Romans and lost a substantial part of their territory. This made them resentful towards Pyrrhus. Therefore, most of them did not join him when he returned to southern Italy. Cassius Dio wrote that the Samnites being hard-pressed by the Romans, caused Pyrrhus to set forth again to come to their assistance. In Plutarch's account, Pyrrhus engaged the Romans despite the lack of Samnite support. The two consuls for 275 BC, Lucius Cornelius Lentulus Caudinus and Manius Curius Dentatus, were fighting in Lucania and Samnium respectively.
