[639] Cecinna said this, and much more to the same purpose, and persuaded them to comply with him; and both he and his army deserted; but still the very same night the soldiers repented of what they had done, and a fear seized on them, lest perhaps Vitellius who sent them should get the better; and drawing their swords, they assaulted Cecinna, in order to kill him; and the thing had been done by them, if the tribunes had not fallen upon their knees, and besought them not to do it; so the soldiers did not kill him, but put him in bonds, as a traitor, and were about to send him to Vitellius. When [Antonius] Primus heard of this, he raised up his men immediately, and made them put on their armor, and led them against those that had revolted; hereupon they put themselves in order of battle, and made a resistance for a while, but were soon beaten, and fled to Cremona; then did Primus take his horsemen, and cut off their entrance into the city, and encompassed and destroyed a great multitude of them before the city, and fell into the city together with the rest, and gave leave to his soldiers to plunder it. And here it was that many strangers, who were merchants, as well as many of the people of that country, perished, and among them Vitellius's whole army, being thirty thousand and two hundred, while Antonius lost no more of those that came with him from Mysia than four thousand and five hundred: he then loosed Cecinna, and sent him to Vespasian to tell him the good news. So he came, and was received by him, and covered the scandal of his treachery by the unexpected honors he received from Vespasian.
