When he found himself beat off at Placentia, he set off to attack Cremona, another large and rich city. In the meantime, Annius Gallus marched to join Spurina at Placentia; but having intelligence that the siege was raised, and that Cremona was in danger, he turned to its relief, and encamped just by the enemy, where he was daily reinforced by other officers. Caecina placed a strong ambush of heavy infantry in some rough and woody country, and gave orders to his horse to advance, and if the enemy should charge them, then to make a slow retreat, and draw them into the snare. But his stratagem was discovered by some deserters to Celsus, who attacked with a good body of horse, but followed the pursuit cautiously, and succeeded in surrounding and routing the troops in the ambuscade; and if the infantry which he ordered up from the camp had come soon enough to sustain the horse, Caecina's whole army, in all appearance, had been totally routed. But Paulinus, moving too slowly, was accused of acting with a degree of needless caution not to have been expected from one of his reputation. So that the soldiers incensed Otho against him, accused him of treachery, and boasted loudly that the victory had been in their power, and that if it was not complete, it was owing to the mismanagement of their generals; all which Otho did not so much believe as he was willing to appear not to disbelieve. He therefore sent his brother Titianus, with Proculus, the prefect of the guards, to the army, where the latter was general in reality, and the former in appearance. Celsus and Paulinus had the title of friends and counsellors, but not the least authority or power. At the same time, there was nothing but quarrel and disturbance amongst the enemy, especially where Valens commanded; for the soldiers here, being informed of what had happened at the ambuscade, were enraged because they had not been permitted to be present to strike a blow in defence of the lives of so many men that had died in that action;Valens, with much difficulty, quieted their fury, after they had now begun to throw missiles at him, and quitting his camp, joined Caecina.
About this time, Otho came to Bedriacum, a little town near Cremona, to the camp, and called a council of war; where Proculus and Titianus declared for giving battle, while the soldiers were flushed with their late success, saying they ought not to lose their time and opportunity and present height of strength, and wait for Vitellius to arrive out of Gaul. But Paulinus told them that the enemy's whole force was present, and that there was no body of reserve behind; but that Otho, if he would not be too precipitate, and chose the enemy's time, instead of his own, for the battle, might expect reinforcements out of Moesia and Pannonia, not inferior in numbers to the troops that were already present. He thought it probable, too, that the soldiers, who were then in heart before they were joined, would not be less so when the forces were all come up.
Besides, the deferring battle could not be inconvenient to them that were sufficiently provided with all necessaries; but the others, being in an enemy's country, must needs be exceedingly straitened in a little time. Marius Celsus was of Paulinus's opinion; Annius Gallus, being absent and under the surgeon's hands through a fall from his horse, was consulted by letter, and advised Otho to stay for those legions that were marching from Moesia. But after all he did not follow the advice; and the opinion of those that declared for a battle prevailed.
There are several reasons given for this determination, but the most apparent is this; that the praetorian soldiers, as they are called, who serve as guards, not relishing the military discipline which they now had begun a little more to experience, and longing for their amusements and unwarlike life among the shows of Rome, would not be commanded, but were eager for a battle, imagining that upon the first onset they should carry all before them. Otho also himself seems not to have shown the proper fortitude in bearing up against the uncertainty, and, out of effeminacy and want of use, had not patience for the calculations of danger, and was so uneasy at the apprehension of it that he shut his eyes, and like one going to leap from a precipice, left everything to fortune. This is the account Secundus the rhetorician, who was his secretary, gave of the matter.
But others would tell you that there were many movements in both armies for acting in concert; and if it were possible for them to agree, then they should proceed to choose one of their most experienced officers that were present; if not, they should convene the senate, and invest it with the power of election. And it is not improbable that, neither of the emperors then bearing the title having really any reputation, such purposes were really entertained among the genuine, serviceable, and sober-minded part of the soldiers. For what could be more odious and unreasonable than that the evils which the Roman citizens had formerly thought it so lamentable to inflict upon each other for the sake of a Sylla or a Marius, a Caesar or a Pompey, should now be undergone anew, for the object of letting the empire pay the expenses of the gluttony and intemperance of Vitellius, or the looseness and effeminacy of Otho? It is thought that Celsus, upon such reflections, protracted the time in order to a possible accommodation; and that Otho pushed on things to an extremity to prevent it.
He himself returned to Brixillum, which was another false step, both because he withdrew from the combatants all the motives of respect and desire to gain his favour which his presence would have supplied, and because he weakened the army by detaching some of his best and most faithful troops for his horse and foot guards.
