About the same time also happened a skirmish on the Po. As Caecina was laying a bridge over it, Otho's men attacked him, and tried to prevent it. And when they did not succeed, on their putting into their boats torchwood, with a quantity of sulphur and pitch, the wind on the river suddenly caught their material that they had prepared against the enemy, and blew it into a light. First came smoke, and then a clear flame, and the men, getting into great confusion and jumping overboard, upset the boats, and put themselves ludicrously at the mercy of their enemies. Also the Germans attacked Otho's gladiators upon a small island in the river, routed them, and killed a good many.
All which made the soldiers at Bedriacum full of anger, and eagerness to be led to battle. So Proculus led them out of Bedriacum to a place fifty furlongs off, where he pitched his camp so ignorantly and with such a ridiculous want of foresight that the soldiers suffered extremely for want of water, though it was the spring time, and the plains all around were full of running streams and rivers that never dried up. The next day he proposed to attack the enemy, first ****** a march of not less than a hundred furlongs; but to this Paulinus objected, saying they ought to wait, and not immediately after a journey engage men who would have been standing in their arms and arranging themselves for battle at their leisure, whilst they were ****** a long march, with all their beasts of burden and their camp followers to encumber them. As the generals were arguing about this matter, a Numidian courier came from Otho with orders to lose no time, but give battle. Accordingly they consented, and moved. As soon as Caecina had notice, he was much surprised, and quitted his post on the river to hasten to the camp. In the meantime, the men had armed themselves mostly, and were receiving the word from Valens; so while the legions took up their position, they sent out the best of their horse in advance.
Otho's foremost troops, upon some groundless rumour, took up the notion that the commanders on the other side would come over; and accordingly, upon their first approach, they saluted them with the friendly title of fellow-soldiers. But the others returned the compliment with anger and disdainful words; which not only disheartened those that had given the salutation, but excited suspicions of their fidelity amongst the others on their side, who had not. This caused a confusion at the very first onset. And nothing else that followed was done upon any plan; the baggage-carriers, mingling up with the fighting men, created great disorder and division; as well as the nature of the ground, the ditches and pits in which were so many that they were forced to break their ranks to avoid and go round them, and so to fight without order, and in small parties. There were but two legions, one of Vitellius's called The Ravenous, and another of Otho's, called The Assistant, that got out into the open outspread level and engaged in proper form, fighting, one main body against the other, for some length of time. Otho's men were strong and bold, but had never been in battle before; Vitellius's had seen many wars, but were old and past their strength. So Otho's legion charged boldly, drove back their opponents, and took the eagle, killing pretty nearly every man in the first rank, till the others, full of rage and shame, returned the charge, slew Orfidius, the commander of the legion, and took several standards. Varus Alfenus, with his Batavians, who are the natives of an island of the Rhine, and are esteemed the best of the German horse, fell upon the gladiators, who had a reputation both for valour and skill in fighting. Some few of these did their duty, but the greatest part of them made towards the river, and, falling in with some cohorts stationed there, were cut off. But none behaved so ill as the praetorians, who, without ever so much as meeting the enemy, ran away, broke through their own body that stood, and put them into disorder. Notwithstanding this, many of Otho's men routed those that were opposed to them, broke right into them, and forced their way to the camp through the very middle of their conquerors.
As for their commanders, neither Proculus nor Paulinus ventured to reenter with the troops; they turned aside, and avoided the soldiers, who had already charged the miscarriage upon their officers.
Annius Gallus received into the town and rallied the scattered parties, and encouraged them with an assurance that the battle was a drawn one and the victory had in many parts been theirs. Marius Celsus, collecting the officers, urged the public interest; Otho himself, if he were a brave man, would not, after such an expense of Roman blood, attempt anything further; especially since even Cato and Scipio, though the liberty of Rome was then at stake, had been accused of being too prodigal of so many brave men's lives as were lost in Africa, rather than submit to Caesar after the battle of Pharsalia had gone against them. For though all persons are equally subject to the caprice of fortune, yet all good men have one advantage she cannot deny, which is this, to act reasonably under misfortunes.
