supposed, was off his guard; on receiving news from several places at once he would hurry from one garrison to another, and might be cut off on his way.  The party told off against the Tenth considered it no light task to storm a legion, so they fell on the soldiers, who had come outside to cut timber, and killed the camp-prefect, five senior centurions, and a handful of the men.  The rest defended themselves in the trenches.  Meanwhile another party of Germans endeavoured to break the bridge[540] which had been begun at Batavodurum, but nightfall put an end to the battle before it was won.

The attack on Grinnes and Vada proved more formidable.  Civilis led 21 the assault on Vada, Classicus on Grinnes.  Nothing could stop them.  The bravest of the defenders had fallen, among them, commanding a cavalry squadron, Briganticus, whom we have seen already, as a faithful ally of Rome and a bitter enemy of his uncle Civilis.[541] However, when Cerialis came to the rescue with a picked troop of horse, the tables were turned, and the Germans were driven headlong into the river.  While Civilis was trying to stop the rout he was recognized, and finding himself a target, he left his horse and swam across the river.  Verax escaped in the same way, while some boats put in to fetch Tutor and Classicus.

Even now the Roman fleet had not joined the army.  They had, indeed, received orders, but fear held them back, and the rowers were employed on various duties elsewhere.  It must be admitted, also, that Cerialis did not give them time enough to carry out his orders.  He was a man of sudden resolves and brilliant successes.  Even when his strategy had failed, good luck always came to his rescue.  Thus neither he nor his army cared much about discipline.  A few days later, again, he narrowly escaped being taken prisoner and did not escape disgrace.  He had 22 gone to Novaesium and Bonn to inspect the winter quarters that were being built for his legions, and was returning with the fleet.[542] The Germans noticed that his escort[543] straggled, and that watch was carelessly kept at night.  So they planned a surprise.  Choosing a night black with clouds they slipped down stream and made their way unmolested into the camp.[544] For the first onslaught they called cunning to their aid.  They cut the tent-ropes and slaughtered the soldiers as they struggled under their own canvas.  Another party fell on the ships, threw hawsers aboard, and towed them off.  Having surprised the camp in dead silence, when once the carnage began they added to the panic by making the whole place ring with shouts.  Awakened by their wounds the Romans hunted for weapons and rushed along the streets,[545] some few in uniform, most of them with their clothes wrapped round their arms and a drawn sword in their hand.  The general, who was half-asleep and almost naked, was only saved by the enemy’s mistake.  His flag-ship being easily distinguishable, they carried
