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. 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.
