Spurinna, on discovering the enemy's route, informed Annius Gallus by letter of the successful defence of Placentia, of what had happened, and of what Caecina intended to do. Gallus was then bringing up the first legion to the relief of Placentia; he hardly dared trust so few cohorts, fearing that they could not sustain a prolonged siege or the formidable attack of the German army. On hearing that Caecina had been repulsed, and was making his way to Cremona, though the legion could hardly be restrained, and in its eagerness for action, even went to the length of open mutiny, he halted at Bedriacum. This is a village situated between Verona and Cremona, and has now acquired an ill-omened celebrity by two great days of disaster to Rome. About the same time Martius Macer fought a successful battle not far from Cremona. Martius, who was a man of energy, conveyed his gladiators in boats across the Padus, and suddenly threw them upon the opposite bank. The Vitellianist auxiliaries on the spot were routed; those who made a stand were cut to pieces, the rest directing their flight to Cremona. But the impetuosity of the victors was checked; for it was feared that the enemy might be strengthened by reinforcements, and change the fortune of the day. This policy excited the suspicions of the Othonianists, who put a sinister construction on all the acts of their generals. Vying with each other in an insolence of language proportioned to their cowardice of heart, they assailed with various accusations Annius Gallus, Suetonius Paullinus, and Marius Celsus. The murderers of Galba were the most ardent promoters of mutiny and discord. Frenzied with fear and guilt, they sought to plunge everything into confusion, resorting, now to openly seditious language, now to secret letters to Otho; and he, ever ready to believe the meanest of men and suspicious of the good, irresolute in prosperity, but rising higher under reverses, was in perpetual alarm. The end of it was that he sent for his brother Titianus, and intrusted him with the direction of the campaign.
Meanwhile, brilliant successes were gained under the command of Celsus and Paullinus. Caecina was greatly annoyed by the fruitlessness of all his undertakings, and by the waning reputation of his army.
He had been repulsed from Placentia; his auxiliaries had been recently cut up, and even when the skirmishers had met in a series of actions, frequent indeed, but not worth relating, he had been worsted;and now that Valens was coming up, fearful that all the distinctions of the campaign would centre in that general, he made a hasty attempt to retrieve his credit, but with more impetuosity than prudence. Twelve miles from Cremona (at a place called the Castors) he posted some of the bravest of his auxiliaries, concealed in the woods that there overhang the road. The cavalry were ordered to move forward, and, after provoking a battle, voluntarily to retreat, and draw on the enemy in hasty pursuit, till the ambuscade could make a simultaneous attack. The scheme was betrayed to the Othonianist generals, and Paullinus assumed the command of the infantry, Celsus of the cavalry. The veterans of the 13th legion, four cohorts of auxiliaries, and 500 cavalry, were drawn up on the left side of the road; the raised causeway was occupied by three Praetorian cohorts, ranged in deep columns; on the right front stood the first legion with two cohorts of auxiliaries and 500 cavalry. Besides these, a thousand cavalry, belonging to the Praetorian guard and to the auxiliaries, were brought up to complete a victory or to retrieve a repulse.
Before the hostile lines engaged, the Vitellianists began to retreat, but Celsus, aware of the stratagem, kept his men back. The Vitellianists rashly left their position, and seeing Celsus gradually give way, followed too far in pursuit, and themselves fell into an ambuscade. The auxiliaries assailed them on either flank, the legions were opposed to them in front, and the cavalry, by a sudden movement, had surrounded their rear. Suetonius Paullinus did not at once give the infantry the signal to engage. He was a man naturally tardy in action, and one who preferred a cautious and scientific plan of operations to any success which was the result of accident. He ordered the trenches to be filled up, the plain to be cleared, and the line to be extended, holding that it would be time enough to begin his victory when he had provided against being vanquished. This delay gave the Vitellianists time to retreat into some vineyards, which were obstructed by the interlacing layers of the vines, and close to which was a small wood. From this place they again ventured to emerge, slaughtering the foremost of the Praetorian cavalry. King Epiphanes was wounded, while he was zealously cheering on the troops for Otho.
