Themistocles held them back until a wind began to blow, which usually arose in the morning, causing a heavy swell in the channel. This seriously incommoded the cumbrous vessels of the Persians, while the light and compact Greek craft easily drove their brazen beaks into the sides of the enemy. The Athenians, on the right, soon broke the Phœnician line which was opposed to them; and the Spartans, on the left, gained victories over the Ionian allies of the Persians. The sea was strewn with dead bodies, entangled in the masts and cordage of the ships. Aristides, who had been waiting with his command on the coast of Salamis, now crossed to the little island of Psyt´tali´a, and put the Persian garrison to the sword. Xerxes, from his throne on Mount Ægaleos, helplessly watched the confusion and slaughter of his men. The contest lasted until evening, when the straits of Salamis were abandoned by the barbarians.

118. When morning came, the Greeks were ready to renew the battle. The Persians had still a large fleet and a numerous army; and, in the night, the Phœnician transports had been joined so as to make a bridge between Salamis and the mainland. But this was only a feint to cover the real movement. The fleet was already under orders to sail to the Hellespont, and the army retired in a few days to Bœotia. Leaving 300,000 men with Mardonius to renew the war in the following year, Xerxes hastened into Asia. His army was reduced on the way by famine and pestilence, and it was but a fragment of the great host which had crossed the Hellespont in the spring of 480, that returned in the autumn.

B. C. 479.

119. As spring opened, Mardonius prepared to renew the war; but first he sought to accomplish by diplomacy what he had hitherto failed to do by force. Deeply impressed with the valor of the Athenians, he was sure that if he could withdraw them from the confederacy, the rest of Greece would be an easy prey. To this end he sent Alexander I., king of Macedon, his ally, but a former friend of the Athenians, to flatter them with promises of favor and solicit their alliance. The Athenians refused him an audience until they had time to summon delegates from Sparta. When the Spartans had arrived, Alexander delivered his message. The great king offered to the Athenians forgiveness of the injuries they had done him, the restoration of their country and its extension over neighboring territories, the free enjoyment of their own laws, and the means of rebuilding all their temples. He urged the Athenians to embrace so favorable an offer, for to them alone of all the Greeks was forgiveness extended.

120. The Athenians replied: “We are not ignorant of the power of the Mede, but for the sake of freedom we will resist that power as we can. Bear back to Mardonius this our answer: So long as yonder sun continues his course, so long we forswear all friendship with Xerxes; so long, confiding in the aid of our gods and heroes, whose shrines and altars he has burnt, we will struggle against him for revenge. As for you, Spartans, knowing our spirit, you should be ashamed to fear our alliance with the barbarian. Send your forces into the field without delay. The enemy will be upon us when he knows our answer. Let us meet him in Bœotia before he proceed to Attica.”

121. The Athenians had rightly judged the immediateness of the danger. Scarcely was their answer received when the Persian general was in motion, and advanced by rapid marches to the borders of Attica. He was re-enforced at every halt by northern Greeks, moved either by terror of his power or by long-standing jealousies against the members of the League. The Attic territory was utterly desolate and Athens a second time deserted. Taking possession of that city, Mardonius dispatched a Greek messenger to Salamis, repeating his former propositions, which were as instantly rejected as before.

The Athenians were a second time homeless, and, for the moment, standing alone against the enemies of Greece. The Spartans were engaged in some long-continued solemnities—perhaps the funeral of their regent, Cleom´brotus—and allowed the Athenian messengers to wait ten days for an answer. Not until the indignant envoys had threatened to make terms with Mardonius and leave Sparta to her fate, did the ephors bestir themselves, but then it was with true Spartan energy and dispatch. Five thousand Spartans and 35,000 slaves were sent, under the command of Pausanias, the new regent, to whom the ephors added a guard of 5,000 heavy-armed Laconians.

122. Hearing of the advance of the Spartans, the Persian thought best to retreat. He again set fire to Athens, leveled to the ground whatever remained of its walls and temples, and retired into Bœotia. Here he arranged his camp on a branch of the Asopus, not far from the city of Platæa. The Spartans followed, having been joined at the isthmus by the Peloponnesian allies, and, at Eleusis, by the Athenians. The Greek forces occupied the lower slopes of Mount Cithæron, with the river before them, separating them from the Persians.

123. Battle of Erythræ. The battle was opened by the Persian cavalry, commanded by Masis´tius, the most illustrious general in the army, except Mardonius. His magnificent person, clad in complete scale-armor of gold and burnished brass, was conspicuous upon the battle-field; and his horsemen, then the most famous in the world for their skill and bravery, severely harassed the Megarians, who were posted on the open plain. Olym´piodo´rus with a select body of Athenians went to their assistance, and Masistius spurred his Nisæan steed across the field to meet him. In the sharp combat which followed, the Persian was unhorsed, and as he lay along the ground was assailed by a swarm of enemies. The heavy armor, which prevented his rising, protected him from their weapons, until, at length, an opening in his visor allowed a lance to reach his brain. His death decided the fate of the battle.

124. After this victory the Greek army moved nearer to Platæa, where was a more abundant supply of water and a more convenient ground. It was the strongest force which the Persians had yet encountered in Greece, numbering, with allies and attendants, 110,000 men. For ten days they lay facing each other with no important action. The Persians, however, intercepted convoys of provisions, and succeeded in choking up the spring which supplied the Greeks with water, while, by their arrows and javelins, they prevented their approach to the river. Pausanias then resolved to fall back to a level and well-watered meadow still nearer to Platæa.
