The Roman History · Amm. 15.5.31

Therefore, after we had secured our success by the address of some agents among the common soldiers, men by their very obscurity fitted for the accomplishment of such a task, and now excited by the expectation of reward, at sunrise, as soon as the east began to redden, a band of armed men suddenly sallied forth, and, as is common in critical moments, behaving with more than usual audacity. They slew the sentinels and penetrated into the palace, and so having dragged Silvanus out of a little chapel in which, in his terror, he had taken refuge on his way to a conventicle devoted to the ceremonies of the Christian worship, they slew him with repeated strokes of their swords.
