Year 293 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Cursor and Maximus (or, less frequently, year 461 Ab urbe condita). The denomination 293 BC for this year has been used since the early medieval period, when the Anno Dominicalendar era became the prevalent method in Europe for naming years.

The camp is captured and looted by the Romans, while the city is eventually taken, with many of the Samnite survivors being slaughtered in the fighting.
