The advice of Themistocles had prevailed on a previous occasion. The revenues from the mines at Laurium had brought great wealth into the Athenians' treasury, and when each man was to receive ten drachmae for his share, Themistocles persuaded the Athenians to make no such division but to use the money to build two hundred ships for the war, that is, for the war with Aegina. This was in fact the war the outbreak of which saved Hellas by compelling the Athenians to become seamen. The ships were not used for the purpose for which they were built, but later came to serve Hellas in her need. These ships, then, had been made and were already there for the Athenians' service, and now they had to build yet others. In their debate after the giving of the oracle they accordingly resolved that they would put their trust in the god and meet the foreign invader of Hellas with the whole power of their fleet, ships and men, and with all other Greeks who were so minded.
