15. Appian Civil Wars 1.39, 1.50 (on the war between Rome and her Italian allies, 90-88 BC)
a. When the revolt broke out [sc. in Asculum] all of the peoples in the vicinity revealed their preparations for war, Marsi, Paeligni, Vestini, Marrucini. Next came the people of Picentia, the Frentani, the Hirpini, the people of Pompeii and Venusia, the Apulians, the Lucanians, and the Samnites. All of these peoples had been disaffected before...They sent ambassadors to Rome. Their complaint was that they had cooperated in all ways with the Romans in the development of their empire but were not deemed worthy of Roman citizenship. The Senate responded quite harshly, saying that they would receive an embassy if the Italians repented of what they had done, but otherwise not. Rejecting all other options the Italians continued their preparations.
b. [In 89] Sulla was camped in the hills near Pompeii. In his contempt for the Romans Lucius Cluentius pitched his own camp only 600 yards away. Not about to put up with the insult, Sulla attacked Cluentius without waiting for the troops who were out foraging. At first he had the worst of it, and retreated, but when he was reinforced by his foragers he turned Cluentius back. Cluentius moved his camp away for the moment, but returned when his numbers were increased by the arrival of some Gauls. When the two armies were about to engage a Gaul of enormous size rushed forward and challenged any Roman to single combat. When a short fellow from North Africa killed him, Cluentius' Gauls were panic-striken and fled. The rest of his line dissolved and headed in disorder for Nola. Sulla followed. About 3000 were killed en route. At Nola only a single gate was opened lest the enemy should rush in with them, so about 20,000 more were killed outside the walls. Among them was Cluentius, who fell fighting. (The next chapters describe Sulla's methods for subduing rebel towns in southern Italy. Nothing more is heard of Pompeii, which seems to have escaped the worst consequences of Sulla's attention. In order to break the revolt Rome eventually granted Roman citizenship to the citizens of the towns of Italy).
