Third Campaign - Capture of Venusia - Fall of Silo
So the third campaign in 666 began amidst favourable prospects for Rome. Strabo put down the last resistance which was still offered in the Abruzzi. In Apulia the successor of Cosconius, Quintus Metellus Pius, son of the conqueror of Numidia and not unlike his father in his strongly conservative views as well as in military endowments, put an end to the resistance by the capture of Venusia, at which 3000 armed men were taken prisoners. In Samnium Silo no doubt succeeded in retaking Bovianum; but in a battle, in which he engaged the Roman general Mamercus Aemilius, the Romans conquered, and--what was more important than the victory itself--Silo was among the 6000 dead whom the Samnites left on the field.
In Campania the smaller townships, which the Samnites still occupied, were wrested from them by Sulla, and Nola was invested. The Roman general Aulus Gabinius penetrated also into Lucania and gained no small advantages; but, after he had fallen in an attack on the enemy's camp, Lamponius the insurgent leader and his followers once more held almost undisturbed command over the wide and desolate Lucano-Bruttian country. He even made an attempt to seize Rhegium, which was frustrated, however, by the Sicilian governor Gaius Norbanus.
Notwithstanding isolated mischances the Romans were constantly drawing nearer to the attainment of their end; the fall of Nola, the submission of Samnium, the possibility of rendering considerable forces available for Asia appeared no longer distant, when the turn taken by affairs in the capital unexpectedly gave fresh life to the well-nigh extinguished insurrection.
