The decisive battle was fought near Trifanum (between Minturnae, Suessa, and Sinuessa) in 414; the consul Titus Manlius Imperiosus Torquatus achieved a complete victory over the united Latins and Campanians.

In the two following years the individual towns, so far as they still offered resistance, were reduced by capitulation or assault, and the whole country was brought into subjection.

The effect of the victory was the dissolution of the Latin league.

It was transformed from an independent political federation into a mere association for the purpose of a religious festival; the ancient stipulated rights of the confederacy as to a maximum for the levy of troops and a share of the gains of war perished as such along with it, and assumed, where they were recognized in future, the character of acts of grace.

Instead of the one treaty between Rome on the one hand and the Latin confederacy on the other, there came at best perpetual alliances between Rome and the several confederate towns.
