Diodorus Siculus

“ The Japyges (of their citizens and confederates) bring into the field about twenty thousand men. The Tarrentines understanding the great preparation made against them, both with their own citizens and confederates of Rhegium, likewise take the field. A bloody battle was fought, and after many killed on both sides, the Japyges became absolute victors; and in the pursuit, the Tarrentines were scattered, and broken into two parties, whereof one fled back to Tarrentum, the other was furiously driven towards Rhegium. ”
