Their commanding officer was Julius Briganticus. He was sister's son to Civilis, and he was hated by his uncle and hated him in return with all the extreme bitterness of a family feud. Tutor, having augmented the army of the Treveri with fresh levies from the Vangiones, the Caeracates, and the Triboci, strengthened it with a force of veteran infantry and cavalry, men from the legions whom he had either corrupted by promises or overborne by intimidation. Their first act was to cut to pieces a cohort, which had been sent on in advance by Sextilius Felix; soon afterwards, however, on the approach of the Roman generals at the head of their army, they returned to their duty by an act of honourable desertion, and the Triboci, Vangiones, and Caeracates, followed their example. Avoiding Mogontiacum, Tutor retired with the Treveri to Bingium, trusting to the strength of the position, as he had broken down the bridge over the river Nava. Asudden attack, however, was made by the infantry under the command of Sextilius; a ford was discovered, and he found himself betrayed and routed. The Treveri were panicstricken by this disaster, and the common people threw down their arms, and dispersed themselves through the country. Some of the chiefs, anxious to seem the first to cease from hostilities, fled to those States which had not renounced the Roman alliance. The legions, which had been removed, as I have before related, from Novesium and Bonna to the territory of the Treveri, voluntarily swore allegiance to Vespasian. These proceedings took place in the absence of Valentinus. When he returned, full of fury and bent on again throwing everything into confusion and ruin, the legions withdrew to the Mediomatrici, a people in alliance with Rome. Valentinus and Tutor again involved the Treveri in war, and murdered the two legates, Herennius and Numisius, that by diminishing the hope of pardon they might strengthen the bond of crime.
Such was the state of the war, when Petilius Cerialis reached Mogontiacum. Great expectations were raised by his arrival. Eager for battle, and more ready to despise than to be on his guard against the enemy, he fired the spirit of the troops by his bold language; for he would, he said, fight without a moment's delay, as soon as it was possible to meet the foe. The levies which had been raised in Gaul he ordered back to their respective States, with instructions to proclaim that the legions sufficed to defend the Empire, and that the allies might return to the duties of peace, secure in the thought that a war which Roman arms had undertaken was finished. This proceeding strengthened the loyalty of the Gauls. Now that their youth were restored to them they could more easily bear the burden of the tribute; and, finding themselves despised, they were more ready to obey. Civilis and Classicus, having heard of the defeat of Tutor and of the rout of the Treveri, and indeed of the complete success of the enemy, hastened in their alarm to concentrate their own scattered forces, and meanwhile sent repeated messages to Valentinus, warning him not to risk a decisive battle.
This made Cerialis move with more rapidity. He sent to the Mediomatrici persons commissioned to conduct the legions which were there by the shortest route against the enemy; and, collecting such troops as there were at Mogontiacum and such as he had brought with himself, he arrived in three days' march at Rigodulum. Valentinus, at the head of a large body of Treveri, had occupied this position, which was protected by hills, and by the river Mosella. He had also strengthened it with ditches and breastworks of stones. These defences, however, did not deter the Roman general from ordering his infantry to the assault, and making his cavalry advance up the hill;he scorned the enemy, whose forces, hastily levied, could not, he knew, derive any advantage from their position, but what would be more than counterbalanced by the courage of his own men. There was some little delay in the ascent, while the troops were passing through the range of the enemy's missiles. As soon as they came to close fighting, the barbarians were dislodged and hurled like a falling house from their position. A detachment of the cavalry rode round where the hills were less steep, and captured the principal Belgic chiefs, and among them Valentinus, their general.
On the following day Cerialis entered the Colony of the Treveri. The soldiers were eager to destroy the city. "This," they said, "is the birthplace of Classicus and Tutor; it was by the treason of these men that our legions were besieged and massacred. What had Cremona done like this, Cremona which was torn from the very bosom of Italy, because it had occasioned to the conquerors the delay of a single night? Here on the borders of Germany stands unharmed a city which exults in the spoils of our armies and the blood of our generals.
