Agrippa and Hero, and Hero Is Possibly Tiberius Claudius Nero

The Yappides have 3,000 warlike and well-armed youths. They also have a number of siege engines which they'd captured earlier in the 40s from Brutus. The Romans managed to capture the wall, and then the people build a second wall inside that. At this point we have the Romans conducting additional siege warfare. In order that the enemy might not fancy that he was going to give in and retire, Octavian began to construct new bridges. He struck terror into the materialians, who thought that they were contending against an unconquerable will. That's from Appian, chapter 20 of the Illyrians.
