Part of the camp occupied the gentle slope of a hill; to part was a level approach. By this encampment Augustus had thought the German tribes might be watched and checked; never had he contemplated such a pitch of disaster, as that these tribes should themselves advance to attack our legions. Hence no labour was bestowed on the ground or on the defences. Our valour and our arms seemed defence enough. The Batavians and the Transrhenane tribes took up their position, each tribe by itself, to distinguish and so the better to display the valour of each; first annoying us by a distant volley; then, as they found that very many of their missiles fixed themselves harmlessly in the turrets and battlements of the walls, and they themselves suffered from the stones showered down on them, they fell on the entrenchment with a shout and furious rush, many placing their scaling-ladders against the ramparts, and others mounting on a testudo formed by their comrades. Some were in the act of climbing over when they were thrust down by the swords of the enemy, and fell overwhelmed by a storm of javelins and stakes. Always very daring at first and excessively elated by success, they now in their eagerness for plunder bore up against reverse. They also ventured to use what to them was a novelty, engines of war; they had themselves no skill in handling them, but the prisoners and deserters taught them to pile up timber in the shape of a bridge, under which they put wheels, and so propelled it, some standing on the top, and fighting as they would from an earth-work, others concealing themselves within and undermining the walls. But the stones thrown by the catapults prostrated the ill-constructed fabric, and when they set themselves to prepare hurdles and mantlets, burning spears were thrown on them by the engines, fire being thus actually used against the assailants. At last, despairing of success by force, they changed their plans, and resolved to wait, for they were well aware that only a few days'
provisions were in the camp, and that there was a great crowd on non-combatants; and they counted at the same time on the treachery that might follow on scarcity, on the wavering fidelity of the slaves, and on the chances of war.
Meanwhile Flaccus, who had heard of the siege of the camp, and had sent into all parts of Gaul to collect auxiliaries, put under command of Dillius Vocula, legate of the 18th legion, some troops picked from the legions with orders to hasten by forced marches along the banks of the Rhine. Flaccus himself, who was weak in health and disliked by his troops, travelled with the fleet. The troops indeed complained in unmistakable language that their general had despatched the Batavian cohorts from Mogontiacum, had feigned ignorance of the plans of Civilis, and was inviting the German tribes to join the league. "This," they said, "has strengthened Vespasian no less than the exertions of Primus Antonius and Mucianus. Declared enmity and hostility may be openly repulsed, but treachery and fraud work in darkness, and so cannot be avoided.
Civilis stands in arms against us, and arranges the order of his battle; Hordeonius from his chamber or his litter gives such orders as may best serve the enemy. The swords of thousands of brave men are directed by one old man's sick caprice. How much better by slaying the traitor, to set free our valour and our fortune from these evil auspices!" The passions already kindled by the language which they thus held among themselves were yet more inflamed by a despatch from Vespasian, which Flaccus, finding that it could not be concealed, read before an assembly of the troops, sending the persons who had brought it in chains to Vitellius.
With feelings somewhat appeased, they arrived at Bonna, the winter-camp of the first legion. The troops there were even more enraged against Hordeonius, and laid on him the blame of the late disaster. They said that it was by his orders that they had offered battle to the Batavians, supposing that the legions from Mogontiacum were following them; that it was through his treachery that they had been slaughtered, no reinforcements coming up; that all these events were unknown to the other legions, and were not told to their Emperor, though the sudden outburst of treason might have been crushed by the prompt action of so many provinces. Hordeonius read to the army copies of all the letters which he had sent about Gaul, begging for reinforcements, and established as a precedent a most disgraceful practice, namely, the handing over the despatches to the standard-bearers of the legions, through whose means they were read by the soldiers sooner than by the generals. He then ordered one of the mutineers to be put in irons, more for the sake of asserting his authority than because any one man was in fault. The army was then moved from Bonna to the Colonia Agrippinensis, while auxiliaries from Gaul continued to flow in; for at first that nation zealously supported the cause of Rome. Soon indeed as the Germans increased in power, many of the states took up arms against us, moved by the hope of ******* and, could they once shake off the yoke, even by the lust of empire. The irritation of the legions still increased, nor had the imprisonment of a single soldier struck them with terror. This fellow indeed actually charged the general with complicity; he had, he said, acted as a messenger between Civilis and Flaccus, and because he might tell the truth he was now being crushed under a false charge.
With wonderful firmness Vocula ascended the tribunal, and ordered the man, who had been seized by the lictors, and was loudly remonstrating, to be led off to execution. All the best men acquiesced in the order, while the ill-affected were struck with terror. Then, as all with common consent demanded that Vocula should be their general, Hordeonius handed over to him the supreme command.
