The war was so far from being at an end, that Civilis in one day attacked on four points the positions of the auxiliary infantry and cavalry and of the legions, assailing the tenth legion at Arenacum, the second at Batavodurum, and the camp of the auxiliary infantry and cavalry at Grinnes and Vada, and so dividing his forces, that he himself, his sister's son Verax, Classicus, and Tutor, led each his own division. They were not confident of accomplishing all these objects, but they hoped that, if they made many ventures, fortune would favour them on some one point. Besides, Cerialis was not cautious, and might easily be intercepted, as the multiplicity of tidings hurried him from place to place. The force, which had to attack the tenth legion, thinking it a hard matter to storm a legionary encampment, surprised some troops, who had gone out, and were busy felling timber, killed the prefect of the camp, five centurions of the first rank, and a few soldiers; the rest found shelter behind the fortifications. At Batavodurum the German troops tried to break down the bridge partly built. Night terminated an indecisive conflict.
There was greater danger at Grinnes and Vada. Civilis attacked Vada, Classicus Grinnes, and they could not be checked, for our bravest men had fallen, among them Briganticus, who commanded a squadron of cavalry, and of whose loyalty to the Roman cause and enmity to his uncle Civilis I have already spoken. But when Cerialis came up with a picked body of cavalry, the fortune of the day changed, and the Germans were driven headlong into the river. Civilis, who was recognised while seeking to stop his flying troops, became the mark of many missiles, left his horse, and swam across the river. Verax escaped in the same way. Some light vessels were brought up, and carried off Tutor and Classicus. Even on this occasion the Roman fleet was not present at the engagement, though orders had been given to that effect. Fear kept them away, and their crews were dispersed about other military duties. Cerialis in fact allowed too little time for executing his commands; he was hasty in his plans, though eminently successful in their results. Fortune helped him even where skill had failed, and so both the general and his army became less careful about discipline. A few days after this he escaped the peril of actual capture, but not without great disgrace.
He had gone to Novesium and Bonna, to inspect the camps which were then in course of erection for the winter abode of the legions, and was making his way back with the fleet, his escort being in disorder, and his sentries negligent. This was observed by the Germans, and they planned a surprise. They chose a dark and cloudy night, and moving rapidly down the stream, entered the entrenchments without opposition. The carnage was at first helped on by a cunning device. They cut the ropes of the tents, and slaughtered the soldiers as they lay buried beneath their own dwellings. Another force put the fleet into confusion, threw their grapling irons on the vessels, and dragged them away by the sterns. They sought at first to elude notice by silence, but when the slaughter was begun, by way of increasing the panic they raised on all sides a deafening shout.
The Romans, awakened by sounds, looked for their arms and rushed through the passages of the camp, some few with their proper accoutrements, but most with their garments wrapped round their shoulders, and with drawn swords in their hands. The general, who was half asleep, and all but naked, was saved by the enemy's mistake. They carried off the praetorian vessel, which was distinguished by a flag, believing that the general was on board.
Cerialis indeed had passed the night elsewhere, in the company, as many believed, of an Ubian woman, Claudia Sacrata. The sentinels sought to excuse their own scandalous neglect by the disgraceful conduct of the general, alleging that they had been ordered to be silent, that they might not disturb his rest, and that, from omitting the watchwords and the usual challenges, they had themselves fallen asleep. The enemy rowed back in broad daylight with the captured vessels. The praetorian trireme they towed up the river Lupia as a present to Veleda.
