In 389 BC, the Volsci took up arms and encamped near the Latin city of Lanuvium. Camillus defeated them and laid "waste all the Volscian countryside, which forced the Volsci to surrender." Livy wrote that with this Rome "acquired undisputed control" of the Pomptine Marshes in the southern part of the Volscian territory. However, the Volsci subsequently continued to fight. Camillus then moved against the Aequi who were preparing for war and defeated them, too. The Etruscans captured the colony of Sutrium in southern Etruria and Camillus repelled them. In 388 BC, the Romans laid waste the territory of the Aequi to weaken them and carried out incursions into the territory of the Etruscan city-state of Tarquinii, capturing and destroying Cortuosa and Contebra. In 386 BC the Volscian of the town of Antium gathered an army which included Hernici and Latin forces near Satricum, not far from Antium. A battle with the Romans was stopped by rain, and the Latins and Hernici then returned home. The Volsci retreated to Satricum, which was taken by storm. In 386 BC, the Etruscans seized Sutrium and Nepet, two Roman colonies in southern Etruria. The Romans asked the Latins and Hernici why they did not provide Rome with soldiers, as they were supposed to, under their alliances. Both replied that it was because of "their constant fear of the Volsci." They also said that their men who had fought with the Volsci had done so of their own volition and not under the orders of their councils. However, it was clear that Rome's aggressive actions had caused them to defect and become hostile. In 385 BC, there was another war with the Volsci, who were supported by the rebelling Latins and Hernici as well as the Roman colony of Circeii and Roman colonists from Velitrae. The force was defeated, and most of the prisoners were Latins and Hernici. The Romans planted a colony with 2000 colonists at Satricum.
