Yet it was to Galba that the legions of Lower Germany took the oath of fidelity annually administered on the first of January. It was done, however, after long delay, and then only by a few voices from the foremost ranks, while the rest preserved an absolute silence, every one waiting for some bold demonstration from his neighbour, in obedience to that innate tendency of men, which makes them quick to follow where they are slow to lead. And even in the various legions there was a difference of feeling. The soldiers of the 1st and of the 5th were so mutinous, that some of them threw stones at the images of Galba. The 15th and 16th legions ventured on nothing beyond uproar and threatening expressions. They were on the watch for something that might lead to an outbreak. In the Upper army, however, the 4th and 13th legions, which were stationed in the same winter-quarters, proceeded on this same first of January to break in pieces the images of Galba, the 4th legion being foremost, the 18th shewing some reluctance, but soon joining with the rest. Not however to seem to throw off all their reverence for the Empire, they sought to dignify their oath with the now obsolete names of the Senate and people of Rome. Not a single legate or tribune exerted himself for Galba; some, as is usual in a tumult, were even conspicuously active in mutiny, though no one delivered anything like a formal harangue or spoke from a tribunal. Indeed there was as yet no one to be obliged by such services.
Hordeonius Flaccus, the consular legate, was present and witnessed this outrage, but he dared neither check the furious mutineers, nor keep the wavering to their duty, nor encourage the well affected. Indolent and timid, he was reserved from guilt only by his sloth. Four Centurions of the 18th legion, Nonius Receptus, Donatius Valens, Romilius Marcellus, Calpurnius Repentinus, striving to protect the images of Galba, were swept away by a rush of the soldiers and put in irons. After this no one retained any sense of duty, any recollection of his late allegiance, but, as usually happens in mutinies, the side of the majority became the side of all. In the course of the night of the 1st of January, the standard-bearer of the 4th legion, coming to the Colonia Agrippinensis, announced to Vitellius, who was then at dinner, the news that the 4th and 18th legions had thrown down the images of Galba, and had sworn allegiance to the Senate and people of Rome. Such a form of oath appeared meaningless. It was determined to seize the doubtful fortune of the hour, and to offer an Emperor to their choice. Vitellius sent envoys to the legions and their legates, who were to say that the army of Upper Germany had revolted from Galba, that it was consequently necessary for them, either to make war on the revolters, or, if they preferred peace and harmony, to create an Emperor, and who were to suggest, that it would be less perilous to accept than to look for a chief.
The nearest winter-quarters were those of the first legion, and Fabius Valens was the most energetic of the legates. This officer in the course of the following day entered the Colonia Agrippinensis with the cavalry of the legion and of the auxiliaries, and together with them saluted Vitellius as Emperor. All the legions belonging to the same province followed his example with prodigious zeal, and the army of Upper Germany abandoned the specious names the Senate and people of Rome, and on the 3rd of January declared for Vitellius. One could be sure that during those previous two days it had not really been the army of the State. The inhabitants of Colonia Agrippinensis, the Treveri, and the Lingones, shewed as much zeal as the army, making offers of personal service, of horses, of arms and of money, according as each felt himself able to assist the cause by his own exertions, by his wealth, or by his talents. Nor was this done only by the leading men in the colonies or the camps, who had abundant means at hand, and might indulge great expectations in the event of victory, but whole companies down to the very ranks offered instead of money their rations, their belts, and the bosses, which, richly decorated with silver, adorned their arms; so strong were the promptings from without, their own enthusiasm, and even the suggestions of avarice.
Vitellius, after bestowing high commendation on the zeal of the soldiers, proceeded to distribute among Roman Knights the offices of the Imperial court usually held by freedmen. He paid the furlough fees to the centurions out of the Imperial treasury. While in most instances he acquiesced in the fury of the soldiers, who clamoured for numerous executions, in some few he eluded it under the pretence of imprisoning the accused. Pompeius Propinquus, procurator of Belgica, was immediately put to death. Julius Burdo, prefect of the German fleet, he contrived to withdraw from the scene of danger. The resentment of the army had been inflamed against this officer by the belief, that it was he who had invented the charges and planned the treachery which had destroyed Capito. The memory of Capito was held in high favour, and with that enraged soldiery it was possible to slaughter in open day, but to pardon only by stealth. He was kept in prison, and only set at liberty after the victory of Vitellius, when the resentment of the soldiery had subsided. Meanwhile, by way of a victim, the centurion Crispinus was given up to them; this man had actually imbued his hands in the blood of Capito. Consequently he was to those who cried for vengeance a more notorious criminal, and to him who punished a cheaper sacrifice.
Julius Civilis, a man of commanding influence among the Batavi, was next rescued from like circumstances of peril, lest that high-spirited nation should be alienated by his execution. There were indeed in the territory of the Lingones eight Batavian cohorts, which formed the auxiliary force of the 14th legion, but which had, among the many dissensions of the time, withdrawn from it; a body of troops which, to whatever side they might incline, would, whether as allies or enemies, throw a vast weight into the scale. Vitellius ordered the centurions Nonnius, Donatius, Romilius, and Calpurnius, of whom I have before spoken, to be executed. They had been convicted of the crime of fidelity, among rebels the worst of crimes. New adherents soon declared themselves in Valerius Asiaticus, legate of the Province of Belgica, whom Vitellius soon after made his son-in-law, and Junius Blaesus, governor of Gallia Lugdunensis, who brought with him the Italian Legion and the Taurine Horse, which was stationed at Lugdunum. The armies of Rhaetia made no delay in at once joining Vitellius, and even in Britain there was no hesitation.
Of that province Trebellius Maximus was governor, a man whose sordid avarice made him an object of contempt and hatred to the army. His unpopularity was heightened by the efforts of Roscius Caelius, the legate of the 20th legion, who had long been on bad terms with him, and who now seized the opportunity of a civil war to break out into greater violence. Trebellius charged him with mutinous designs, and with disturbing the regularity of military discipline; Caelius retorted on Trebellius the accusation of having plundered and impoverished the legions. Meanwhile all obedience in the army was destroyed by these disgraceful quarrels between its commanders, and the feud rose to such a height that Trebellius was insulted even by the auxiliaries, and finding himself altogether isolated, as the infantry and cavalry sided with Caelius, he fled for safety to Vitellius. Yet the province still enjoyed tranquility, though its consular governor had been driven from it. It was now ruled by the legates of the legions, who were equal as to lawful authority, though the audacity of Caelius made him the more powerful.
After the army of Britain had joined him, Vitellius, who had now a prodigious force and vast resources, determined that there should be two generals and two lines of march for the contemplated war. Fabius Valens was ordered to win over, if possible, or, if they refused his overtures, to ravage the provinces of Gaul and to invade Italy by way of the Cottian Alps; Caecina to take the nearer route, and to march down from the Penine range. To Valens were entrusted the picked troops of the army of Lower Germany with the eagle of the 5th legion and the auxiliary infantry and cavalry, to the number of 40,000 armed men; Caecina commanded 30,000 from Upper Germany, the strength of his force being one legion, the 21st. Both had also some German auxiliaries, and from this source
