The legions had caught the infection of mutiny, and next assailed Aponius Saturnius, legate of the army of Moesia, this time the more furiously because their rage broke out, not as before, when they were wearied with labour and military toils, but at mid-day. Some letters had been published, which Saturninus was believed to have written to Vitellius. If once they had emulated each other in valour and obedience, so now there was a rivalry in insubordination and insolence, till they clamoured as violently for the execution of Aponius as they had for that of Flavianus. The legions of Moesia recalled how they had aided the vengeance of the Pannonian army, while the soldiers of Pannonia, as if they were absolved by the mutiny of others, took a delight in repeating their fault. They hastened to the gardens in which Saturninus was passing his time, and it was not the efforts of Primus Antonius, Aponianus, and Messalla, though they exerted themselves to the uttermost, that saved him, so much as the obscurity of the hiding-place in which he concealed himself, for he was hidden in the furnace of some baths that happened to be out of use. In a short time he gave up his lictors, and retired to Patavium. After the departure of the two men of consular rank, all power and authority over the two armies centred in Antonius alone, his colleagues giving way to him, and the soldiers being strongly biased in his favour. There were those who believed that both these mutinies were set on foot by the intrigues of Antonius, in order that he might engross all the prizes of the war.
Nor indeed was there less restlessness among the partisans of Vitellius, who were distracted by yet more fatal dissensions, springing, not from the suspicions of the common men, but from the treachery of the generals. Lucilius Bassus, prefect of the Ravenna fleet, finding that the troops wavered in purpose, from the fact that many were natives of Dalmatia and Pannonia, provinces held for Vespasian, had attached them to the Flavianist party. The night-time was chosen for accomplishing the treason, because then, unknown to all the rest, the ringleaders alone might assemble at head-quarters.
Bassus, moved by shame, or perhaps by fear, awaited the issue in his house. The captains of the triremes rushed with a great outcry on the images of Vitellius; a few, who attempted to resist, were cut down; the great majority, with the usual love of change, were ready to join Vespasian. Then Bassus came forward and openly sanctioned the movement. The fleet appointed Cornelius Fuscus to be prefect, and he hastened to join them. Lucilius was put under honourable arrest, and conveyed as far as Adria by the Liburnian ships; there he was thrown into prison by Vivennius Rufinus, prefect of a squadron of cavalry, which was there in garrison. His chains, however, were immediately struck off on the interference of Hormus, one of the Emperor's freedmen, for he too ranked among the generals.
On the revolt of the fleet becoming known, Caecina called together to head-quarters, which he purposely selected as being the most retired part of the camp, the chief centurions and some few soldiers, while the rest were dispersed on various military duties.
Then he extolled the valour of Vespasian, and the strength of his party; he told them that the fleet had changed sides, that they were straitened for supplies, that Gaul and Spain were against them, that in the capital there was nothing on which to rely, thus ****** the worst of everything that concerned Vitellius. Then, the conspirators present setting the example, and the rest being paralysed by the strangeness of the proceeding, he made them swear allegiance to Vespasian. At the same time the images of Vitellius were torn down, and persons were despatched to convey the intelligence to Antonius.
But when this treason became noised abroad throughout the camp, when the soldiers, hurrying back to head-quarters, saw the name of Vespasian written on the colours, and the images of Vitellius thrown upon the ground, first there was a gloomy silence, then all their rage burst out at once. "What," they cried, "has the glory of the army of Germany fallen so low, that without a battle, even without a wound, they should yield up hands ready bound and arms resigned to surrender?
What legions indeed are these against us? Only the conquered. The first and the twelfth, the sole strength of the Othonianist army, are not there, and even them we routed and crushed on these very plains, only that so many thousands of armed men, like a herd of slaves for sale, might be given as a present to the exile Antonius.
Thus, forsooth, the adhesion of one fleet would be worth eight legions. So it pleases Bassus and Caecina, after robbing the Emperor of palaces, gardens, and money, to rob the soldiers of their Emperor. But we, who have seen nothing of toil and bloodshed, we, who must be contemptible even to the Flavianists, what shall we answer to those who shall ask us of our victories and our defeats?"Joining one and all in these cries, by which each expressed his own vexation, they proceeded, following the lead of the fifth legion, to replace the images of Vitellius, and to put Caecina in irons. They elected to the command Fabius Fabullus, legate of the fifth legion, and Cassius Longus, prefect of the camp; they massacred the soldiers from three Liburnian ships, who happened to fall in their way, but who were perfectly ignorant and innocent of these proceedings; they then abandoned the camp, and, after breaking down the bridge, fell back on Hostilia, and thence on Cremona, in order to effect a junction with the two legions, the 1st Italica and the 21st Rapax, which, with a portion of the cavalry, Caecina had sent on to occupy Cremona.
