Such arguments as these were already circulating openly in the camp, when the first day of the first month came, which the Romans call the Calends of January. On this day Flaccus assembled the soldiers that they might take the customary oath of allegiance to the emperor; but they overturned and pulled down all the statues of Galba which they could find, and after swearing allegiance to the senate and people of Rome, went to their quarters.
Then their officers began to fear that their lawless spirit might issue in revolt, and one of them made this speech: What is wrong with us, my fellow soldiers? We are neither supporting the present emperor nor setting up another. It is as though we were averse, not to Galba, but to all rule and obedience.
