Histories

When he reached his voyage's destination, Miltiades with his army drove the Parians inside their walls and besieged them; he sent in a herald and demanded a hundred talents, saying that if they did not give it to him, his army would not return home before it had stormed their city.

The Parians had no intention of giving Miltiades any money at all, and they contrived how to defend their city. They did this by building their wall at night to double its former height where it was most assailable, and also by other devices.
