5. It so happened by chance that Gnaeus and Lucius Gavillius Novellus, from Aquileia, coming with provisions and not knowing what had happened, almost stumbled upon the camp which had been taken by the Histrians. [2] When they, leaving their belongings, had fled to Aquileia, they filled everything with consternation and confusion, not only at Aquileia, but also, a few days later, at Rome; [3] where the report was brought not merely that the camp had been captured by the enemy and that the Romans had fled (as was the case), but also that all was lost and the whole army destroyed. [4] And so, as is usually done in times of panic, extraordinary levies were proclaimed not in the City alone but throughout Italy. Two legions of Roman citizens were enlisted and ten thousand infantry with five hundred cavalry were levied upon the allies of the Latin confederacy. Marcus Junius the consul was directed to cross into Gaul and to demand from the states of that province as many soldiers as each could furnish. [5] At the same time it was decreed that Tiberius Claudius the praetor¹ should issue an edict to the soldiers of the [6??] fourth legion and to five thousand foot and two hundred and fifty horse of the allies of the Latin confederacy that they should assemble at Pisa, and that Claudius should defend that province during the consul's absence; [7] and also [p. 199]that Marcus Titinius the praetor² should order the³ first legion⁴ and an equal number of infantry and cavalry of the allies to assemble at Rimini. [8] Nero in uniform set out for his province at Pisa; Titinius first sent Gaius Cassius, a tribune of the soldiers, to Rimini as commander of the legion and then conducted the levy at Rome. [9] Marcus Junius the consul, having gone over from the Ligurians into the province of Gaul, and having immediately levied upon the Gallic states for auxiliaries and upon the colonies for regular troops, arrived at Aquileia. [10] There he was informed that the army was safe, and sending despatches to Rome in order to allay their fears, he himself sent home the auxiliaries which he had levied on the Gauls and set out to join his colleague. [11] At Rome there was great and unexpected joy; the levy was stopped, the soldiers who had taken the military oath were discharged, and the army, which had been suffering from a plague at Rimini, was sent home. [12] Although the Histrians had a strong force in camp not far from the consul's camp, when they learned that the other consul with a new army had arrived they dispersed to their various states. The consuls led the legions into winter-quarters at Aquileia.
