More, however, eluded discovery, escaping either through the faithful protection of friends or by their own tact. Thus the preparations of Vitellius became known, while the plans of Vespasian were for the most part kept secret. At first the supineness of Vitellius was in fault; afterwards the occupation of the Pannonian Alps with troops stopped all intelligence. And on the sea the prevalent Etesian winds favoured an eastward voyage, but hindered all return.
At length Vitellius, appalled by the irruption of the enemy and by the menacing intelligence from every quarter, ordered Caecina and Valens to take the field. Caecina was sent on in advance; Valens, who was just recovering from a severe illness, was delayed by weakness. Far different was the appearance of the German army as it marched out of the capital. All strength had departed from their bodies, all energy from their spirits. Slowly, and with thin ranks, the column moved along, their weapons feebly grasped, their horses spiritless. The soldiers, impatient of the heat, the dust, and the weather, in proportion as they were less capable of enduring toil, were more ready for mutiny. All this was aggravated by the old vanity of Caecina, and by the indolence that had of late crept over him; presuming on the excessive favour of fortune, he had abandoned himself to luxury. Perhaps he meditated perfidy, and it was part of his policy to enervate the courage of the army. Many believe that his fidelity had been shaken by the suggestions of Flavius Sabinus, who employed Rubrius Gallus as the bearer of communications intimating that the conditions of desertion would be held binding by Vespasian.
At the same time he was reminded of his hatred and jealousy of Fabius Valens. Being inferior to his rival in influence with Vitellius, he should seek to secure favour and power with the new Emperor.
Caecina, having embraced Vitellius and received tokens of high distinction, left him, and sent a detachment of cavalry to occupy Cremona. It was followed by the veteran troops of the 4th, 10th, and 16th legions, by the 5th and 22nd legions, and the rear was brought up by the 21st (the Rapax) and the first Italian legion with the veteran troops of three British legions, and a chosen body of auxiliaries. After the departure of Caecina, Valens sent a despatch to the army which had been under his own command with directions that it should wait for him on the road; such, he said, was his arrangement with Caecina. Caecina, however, being with the army in person, and consequently having greater influence, pretended that this plan had been changed, so that the gathering forces of the enemy might be met with their whole strength. Orders were therefore given to the legions to advance with all speed upon Cremona, while a portion of the force was to proceed to Hostilia. Caecina himself turned aside to Ravenna, on the pretext that he wished to address the fleet. Soon, however, he sought the retirement of Patavium, there to concert his treachery. Lucilius Bassus, who had been promoted by Vitellius from the command of a squadron of cavalry to be admiral of the fleets at Ravenna and Misenum, failing immediately to obtain the command of the Praetorian Guard sought to gratify his unreasonable resentment by an atrocious act of perfidy. It cannot be certainly known whether he carried Caecina with him, or whether (as is often the case with bad men, that they are like each other) both were actuated by the same evil motives.
The historians of the period, who during the ascendancy of the Flavian family composed the chronicles of this war, have in the distorted representations of flattery assigned as the motives of these men a regard for peace and a love of their country. For my own part I believe that, to say nothing of a natural fickleness and an honour which they must have held cheap after the betrayal of Galba, feelings of rivalry, and jealousy lest others should outstrip them in the favour of Vitellius, made them accomplish his ruin. Caecina, having overtaken the legions, strove by every species of artifice to undermine the fidelity of the centurions and soldiers, who were devoted to Vitellius. Bassus, in ****** the same attempt, experienced less difficulty, for the fleet, remembering how recently it had served in the cause of Otho, was ready to change its allegiance.
