Persia lost her European provinces, and began the struggle to retain those of Asia.
Terminus receded, and having once receded never advanced again in this quarter.

The Greeks took the offensive.

Sailing to Asia, they not only liberated from their Persian bondage the islands which lay along the coast, but landing their men on the continent, attacked and defeated an army of 60,000 Persians at Mycale, and destroyed the remnant of the ships that had escaped from Salamis.

Could they have made up their minds to maintain a powerful fleet permanently on the coast of Asia, they might at once have deprived Persia of her whole sea-hoard on the Propontis and the Egean; but neither of the two great powers of Greece was prepared for such a resolve.

Sparta disliked distant expeditions; and Athens did not as yet see her way to undertaking the protection of the continental Greeks.
