Plutarch Otho 3

[1] And now that the emperor had given the people this most righteous gratification, he did not remember his own private grievances against any man soever, and in his desire to please the multitude did not refuse at first to be hailed in the theatres by the name of Nero, and when statues of Nero were produced in public, he did not prevent it.

[2] Moreover, Cluvius Rufus tells us that diplomas, ¹ such as couriers are provided with, were sent to Spain, in which the cognomen of Nero was added to the name of Otho. However, perceiving that the men of highest birth and greatest influence were displeased at this, Otho gave up the practice.
  But while he was placing his government on this basis, the paid soldiers began to make themselves troublesome by urging him not to trust the influential citizens, but to be on his guard against them and restrict their power. It is uncertain whether their goodwill led them to be really apprehensive for him, or whether they used this pretext for raising disturbance and war.

[3] And so, when the emperor sent Crispinus to bring back the seventeenth legion from Ostia, and while that officer was still getting the baggage together at night and loading the arms upon the waggons, the boldest of the soldiers all began to cry out that Crispinus was come on no good errand, and that the senate was attempting to bring about a revolution, and that the transportation of the arms was an act of hostility, not of service, to the emperor.

[4] The notion prevailed with great numbers and exasperated them; some attacked the waggons, others killed two centurions who opposed them, as well as Crispinus himself; and then the whole body, putting themselves in array and exhorting one another to go to the help of the emperor, marched to Rome. Here, learning that eighty senators were at supper with Otho, they rushed to the palace, declaring that now was a good time to take off all the emperor’s enemies at one stroke.

[5] Accordingly, the city was in great commotion, expecting to be plundered at once; in the palace there were runnings to and fro; and a dire perplexity fell upon Otho. For while he had fears about the safety of his guests, he himself was an object of fear to them, and he saw that they kept their eyes fixed upon him in speechless terror, some of them having even brought their wives with them to the supper.

[6] But he sent the prefects of the guard with orders to explain matters to the soldiers and appease them, while at the same time he dismissed his guests by another door; and they barely succeeded in making their escape as the soldiers, forcing their way through the guards into the great hall, asked what was become of the enemies of Caesar.

[7] In this crisis, then, Otho stood up on his couch, and after many exhortations, and entreaties, and not without plentiful tears, at last succeeded in sending them away; but on the following day, after making a gift of twelve hundred and fifty drachmas to every man, he went into the camp.

[8] There he commended the great body of the soldiers for their goodwill and zeal in his service, but said that there were a few of them who were intriguing to no good purpose, thereby bringing his moderation and their fidelity into disrepute, and he demanded that they share his resentment against these and assist him in punishing them. All his hearers approving of this and bidding him to do as he wished, he took two men only, at whose punishment no one was likely to be distressed, and went away.
