Valens received the tidings of the murder of Galba and the accession of Otho while he was in the country of the Leuci. The feelings of the soldiers were not seriously affected either with joy or alarm;they were intent on war. Gaul however ceased to hesitate: Otho and Vitellius it hated equally, Vitellius it also feared. The next territory was that of the Lingones who were loyal to Vitellius. The troops were kindly received, and they vied with each other in good behaviour. This happy state of things, however, was of short duration owing to the violence of the auxiliary infantry, which had detached itself, as before related, from the 14th legion, and had been incorporated by Valens with his army. First came angry words, then a brawl between the Batavi and the legionaries, which as the partialities of the soldiers espoused one or another of the parties was almost kindled into a battle, and would have been so, had not Valens by punishing a few, reminded Batavi of the authority which they had now forgotten. Against the Aedui a pretext for war was sought in vain. That people, when ordered to furnish arms and money, voluntarily added a supply of provisions. What the Aedui did from fear, the people of Lugdunum did with delight. Yet the Italian legion and the Taurine Horse were withdrawn. It was resolved that the 18th cohort should be left there, as it was their usual winter quarters. Manlius Valens, legate of the Italian legion, though he had served the party well, was held in no honour by Vitellius. Fabius Valens had defamed him by secret charges of which he knew nothing, publicly praising him all the while, that he might the less suspect the treachery.
The old feud between Lugdunum and Vienna had been kindled afresh by the late war. They had inflicted many losses on each other so continuously and so savagely that they could not have been fighting only for Nero or Galba. Galba had made his displeasure the occasion for diverting into the Imperial treasury the revenues of Lugdunum, while he had treated Vienna with marked respect. Thence came rivalry and dislike, and the two states, separated only by a river, were linked together by perpetual feud. Accordingly the people of Lugdunum began to work on the passions of individual soldiers, and to goad them into destroying Vienna, by reminding them, how that people had besieged their colony, had abetted the attempts of Vindex, and had recently raised legions for Galba. After parading these pretexts for quarrel, they pointed out how vast would be the plunder. From secret encouragement they passed to open entreaty. "Go,"they said, "to avenge us and utterly destroy this home of Gallic rebellion. There all are foreigners and enemies; we are a Roman colony, a part of the Roman army, sharers in your successes and reverses. Fortune may declare against us. Do not abandon us to an angry foe."By these and many similar arguments they so wrought upon the troops, that even the legates and the leaders of the party did not think it possible to check their fury; but the people of Vienna, aware of their danger, assumed the veils and chaplets of suppliants, and, as the army approached, clasped the weapons, knees and feet of the soldiers, and so turned them from their purpose. Valens also made each soldier a present of 300 sesterces. After that the antiquity and rank of the colony prevailed, and the intercession of Valens, who charged them to respect the life and welfare of the inhabitants, received a favourable hearing. They were however publicly mulcted of their arms, and furnished the soldiers with all kinds of supplies from their private means. Report, however, has uniformly asserted, that Valens himself was bought with a vast sum. Poor for many years and suddenly growing rich, he could but ill conceal the change in his fortunes, indulging without moderation the appetites which a protracted poverty had inflamed, and, after a youth of indigence, becoming prodigal in old age. The army then proceeded by slow marches through the territory of the Allobroges and Vocontii, the very length of each day's march and the changes of encampment being made a matter of traffic by the general, who concluded disgraceful bargains to the injury of the holders of land and the magistrates of the different states, and used such menaces, that at Lucus, a municipal town of the Vocontii, he was on the point of setting fire to the place, when a present of money soothed his rage. When money was not forthcoming he was bought off by sacrifices to his lust. Thus he made his way to the Alps.
Caecina revelled more freely in plunder and bloodshed. His restless spirit had been provoked by the Helvetii, a Gallic race famous once for its warlike population, afterwards for the associations of its name. Of the murder of Galba they knew nothing, and they rejected the authority of Vitellius. The war originated in the rapacity and impatience of the 21st legion, who had seized some money sent to pay the garrison of a fortress, which the Helvetii had long held with their own troops and at their own expense. The Helvetii in their indignation intercepted some letters written in the name of the army of Germany, which were on their way to the legions of Pannonia, and detained the centurion and some of his soldiers in custody. Caecina, eager for war, hastened to punish every delinquency, as it occurred, before the offender could repent. Suddenly moving his camp he ravaged a place, which during a long period of peace had grown up into something like a town, and which was much resorted to as an agreeable watering place. Despatches were sent to the Rhaetian auxiliaries, instructing them to attack the Helvetii in the rear while the legion was engaging them in front.
