From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
By the defection of this town, which lay on the military road from Campania to Samnium, Aesernia was isolated, and that fortress already vigorously assailed found itself now exclusively dependent on the courage and perseverance of its defenders and their commandant Marcellus. It is true that an incursion, which Sulla happily carried out with the same artful audacity as formerly his expedition to Bocchus, relieved the hard-pressed Aesernians for a moment; nevertheless they were after an obstinate resistance compelled by the extremity of famine to capitulate towards the end of the year. In Lucania too Publius Crassus was defeated by Marcus Lamponius, and compelled to shut himself up in Grumentum, which fell after a long and obstinate siege.
With these exceptions, they had been obliged to leave Apulia and the southern districts totally to themselves. The insurrection spread; when Mutilus advanced into Campania at the head of the Samnite army, the citizens of Nola surrendered to him their city and delivered up the Roman garrison, whose commander was executed by the orders of Mutilus, while the men were distributed through the victorious army. With the single exception of Nuceria, which adhered firmly to Rome, all Campania as far as Vesuvius was lost to the Romans; Salernum, Stabiae, Pompeii, Herculaneum declared for the insurgents; Mutilus was able to advance into the region to the north of Vesuvius, and to besiege Acerrae with his Samnito-Lucanian army.
