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.
