History of the Peloponnesian War

Every armament was most terrible at first; if it allowed time to run on without showing itself, men's courage revived, and they saw it appear at last almost with indifference. By attacking suddenly, while Syracuse still trembled at their coming, they would have the best chance of gaining a victory for themselves and of striking a complete panic into the enemy by the aspect of their numbers—which would never appear so considerable as at present—by the anticipation of coming disaster, and above all by the immediate danger of the engagement.
