In 334 BC, the Romans advanced into the Liris valley, which the Samnites found that to be an unacceptable intrusion by Rome, but were too preoccupied to respond at the time[1] as they were involved in a conflict with the Greek colony of Tarentum and its ally, Alexander of Epirus.

Citizens hatched a plot to allow the Roman forces entry into the city under the cover of night.
The capture of Neapolis was just one of the numerous conflicts during a war that was to last for over 20 years and exact tremendous sacrifices from both sides.
