Counsels were divided. The Delphian oracle had obscurely declared, "When everything else in the land of Cecrops shall be taken, Zeus grants to Athena that the wooden walls alone shall remain unconquered, to defend you and your children." The oracle was believed to be, as was declared, "firm as adamant."

But there were various opinions as to what was meant by the "wooden walls." Some thought the Pythian priestess directed the Athenians to seek refuge in the forests on the mountains; but Themistocles (who it is thought may have himself prompted the oracle) contended that the ships were plainly indicated.

The last interpretation was acted upon. All the soldiers of Attica were crowded upon the vessels of the fleet at Salamis. The aged men, with the women and children, were carried out of the country to different places of safety. All the towns of Attica, with the capital, were thus abandoned to the conquerors.

A few days afterwards the Persians entered upon the deserted plain, which they rendered more desolate by ravaging the fields and burning the empty towns. Athens shared the common fate, and her splendid temples sank in flames. Sardis was avenged. The joy in distant Susa was unbounded.

THE NAVAL BATTLE OF SALAMIS (480 B.C.).—Just off the coast of Attica, separated from the mainland by a narrow passage of water, lies the island of Salamis. Here lay the Greek fleet, awaiting the Persian attack. To hasten on the attack before dissensions should divide the Greek forces, Themistocles resorted to the following stratagem. He sent a messenger to Xerxes representing that he himself was ready to espouse the Persian cause, and advised an immediate attack upon the Athenian fleet, which he represented as being in no condition to make any formidable resistance. Xerxes was deceived. He ordered an immediate attack. From a lofty throne upon the shore he himself overlooked the scene and watched the result. The Persian fleet was broken to pieces and two hundred of the ships destroyed. [Footnote: The entire Persian fleet numbered about seven hundred and fifty vessels; the Grecian, about three hundred and eighty-five ships, mostly triremes.]

The blow was decisive. Xerxes, fearing that treachery might burn or break the Hellespontine bridges, instantly despatched a hundred ships to protect them; and then, leaving Mardonius with three hundred thousand men to retrieve the disaster of Salamis, and effect, as he promised to do, the conquest of the rest of Greece, the monarch set out on his ignominious retreat to Asia. [Footnote: On the very day of the battle of Salamis, Gelon of Syracuse gained a great victory over the Carthaginians at the battle of Himera, in the north of Sicily. So it was a memorable day for Hellas in the West as well as in the East.]

THE BATTLES OF PLATÆA AND MYCALE (479 B.C.).—The next year the Persian fleet and army thus left behind in Europe were entirely destroyed, both on the same day—the army at Platæa, near Thebes, by the combined Greek forces under the Spartan Pausanias; and the fleet, including the Asiatic land forces, at Mycale, on the Ionian coast.

The battles of Salamis, Platæa, and Mycale were the successive blows that shattered into fragments the most splendid armaments ever commanded by Asiatic despot.

MEMORIALS AND TROPHIES OF THE WAR.—The glorious issue of the war caused a general burst of joy and exultation throughout all Greece. Poets, artists, and orators, all vied with one another in commemorating the deeds of the heroes whose valor had warded off the impending danger.

Nor did the pious Grecians think that the marvellous deliverance had been effected without the intervention of the gods in their behalf. To the temple at Delphi was gratefully consecrated a tenth of the immense spoils in gold and silver from the field of Platæa; and within the sanctuary of Athena, upon the Acropolis at Athens, were placed the broken cables of the Hellespontine bridges, at once a proud trophy of victory, and a signal illustration of the divine punishment that had befallen the audacious and impious attempt to lay a yoke upon the sacred waters of the Hellespont.
