BATTLE // -339 BCE

Battle of Trifanum

Source · Wikipedia

Significance

The Battle of Trifanum was an engagement of the Second Latin War fought in 340 BCE, following directly from the Battle of Vesuvius. Roman forces under Manlius Imperiosus pursued the retreating Latin League northward and brought them to battle near the mouth of the Liri River at Trifanum. Livy records the Roman victory as so complete that the Latins submitted when the consul subsequently entered Latium, yet the war continued for a further two years, suggesting the outcome fell short of a decisive capitulation. One interpretation consistent with both accounts is that the Latins were caught by surprise and dispersed rather than formally defeated in set battle. The engagement nonetheless represented a significant moment in Rome's effort to suppress the Latin League revolt, demonstrating the capacity of Roman forces to maintain operational pressure after Vesuvius and to deny the Latins the opportunity to regroup.

Tactics

The two armies met while on the march near Trifanum. According to Livy, both forces dumped their baggage and fought on the spot where they encountered each other, indicating an engagement that developed from contact rather than deliberate preparation or chosen ground.
