Otho (3.5-3.6)

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.

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.
