In 380 BC, the Praenestines marched into the territory of Gabii and advanced against Rome's walls at the Colline Gate and encamped near the River Allia, where the Gauls had defeated Rome. The Romans defeated them and marched into the territory of Praeneste, seizing eight towns under its jurisdiction and then Velitrae. Finally, they confronted Praeneste, the heart of the rebellion, which surrendered. In 378 BC, the Volsci ravaged the borders of Roman territory. The Romans sent an army to Antium on the coast and another to Electra and the mountains and applied a scorched earth policy. In 377 BC, a joint Latin and Volscian force encamped near Satricum. The Romans levied three armies: one was a reserve legion, one defended the city and the third, the largest, marched on Satricum. The enemy were routed and fled to Antium. A quarrel now broke out between the Antiates and the Latins. The former were inclined to give up, but the latter did not and left. The Antiates surrendered their city and lands. The Latins burned Satricum in revenge. Then, they attacked Tusculum, which was rescued by the Romans.
