The Persians had been driven out of Greece, and the war with them was now carried on in Asia Minor instead of nearer home. The Greek army won many battles here also, and even managed to free the city of Miletus from the Persian yoke.

These triumphs encouraged all the Ionian cities, and they soon formed a league with the other Greeks, promising to help them against the Persians should the war ever be renewed. As soon as this alliance was made, the Greek fleet returned home, bringing back to Athens as a trophy the chains with which Xerxes had pretended to bind the rebellious sea.
