“We have been ordered to hold the pass, and a Spartan obeys orders, and never surrenders, no matter what happens.”

So there Leonidas and his thousand men fought to the bitter end until all except one of their number was killed.

The gateway to the city of Athens was now open, and things looked very black for the Greeks, for there was nothing to prevent the Persians from marching over the dead bodies of Leonidas and his men straight on to Athens.

The Athenians, wondering what was to happen to them, hurriedly went to the oracle at Delphi and asked what they should do.

The oracle replied that the city of Athens itself was doomed, that it would be destroyed, there was no hope for it, but that the Athenians themselves would be saved by wooden walls.

This answer, as was usually the case in whatever the oracle said, was a riddle, the meaning of which seemed hard to solve. Themistocles, however, said that he knew the answer. You remember that it was he who had been working so hard to have a fleet of ships built. Themistocles said that the oracle meant these ships when it spoke of the wooden walls.

So the Athenians, following the supposed advice of the oracle, left their city as Themistocles told them and went on board the ships, which were not far away, in a bay called Salamis.

The Persian army reached Athens and found it deserted. So they burned and destroyed the city as the oracle said. Then they marched on to the Bay of Salamis, where the Athenians were on board the ships. There, on a hill overlooking the bay, Xerxes had a throne built for himself so that he could sit, as if in a box at the theater looking at a play, and watch his own large fleet destroy the much smaller one of the Greeks with all the Athenians on board.

The Greek fleet was commanded, of course, by Themistocles. His ships were in this narrow bay or strait of water, somewhat in the same way that the soldiers of Leonidas had been in the narrow valley at Thermopylæ.
