The Third Samnite War broke out over territory near
Naples in 298 BC, as the last Samnite attempt to ward off Roman domination. Rome sent two armies against Samnium, led by the experienced consuls
Quintus Fabius Maximus Rullianus and
Publius Decius Mus, each with about 20,000 men. The Samnite army numbered 25,000. The Samnites hoped to defeat each Roman army in detail; therefore, they set an ambush for Rullianus in a valley near 'Tifernum' (Livy here probably intended to use the term
Tifernus instead). Rullianus, with proper scouting, discovered the trap and would not enter the valley. Fearing the arrival of the other Roman army if they delayed, the Samnites came out of the valley and offered battle, which Rullianus duly accepted. The battle lines clashed and the Samnites were getting the upper hand when, suddenly, in the Samnite rear, there appeared a force of Roman
hastati, led by the Tribune
Lucius Cornelius Scipio Barbatus, that Rullianus had previously sent on a flanking march before the battle had begun. With both sides thinking this small detachment heralded the arrival of the army of Decius Mus, the Roman morale soared while that of the Samnites collapsed, and they fled the battle. The badly shaken Romans were in no shape to pursue, and so, with Samnite casualties fairly low, the Samnites were still in shape to continue the war. == Battle details ==
