Three years afterwards the consul Publius Decius Mus captured several of the Volsinian fortresses. In 295 BC, Lucius Postumius Megellus ravaged their territory and defeated them under the walls of their own city, slaying 2,800 of them. Consequently they, together with Perusia (modern Perugia) and Arretium, purchased a forty-year peace by paying a heavy fine.
