[Illustration: AN ATHENIAN TRIREME (Reconstruction) A trireme is supposed to have had three tiers or banks of oars, placed one above the other. Each tier thus required an oar about a yard longer than the one immediately beneath it. There were about two hundred rowers on a trireme.] AFTER SALAMIS The victory at Salamis had important results. It so crippled the Persians that henceforth they lost command of the sea. Xerxes found it difficult to keep his men supplied with provisions and at once withdrew with the larger part of his force to Asia. The Great King himself had no heart for further fighting, but he left Mardonius, with a strong body of picked troops, to subjugate the Greeks on land. So the real crisis of the war was yet to come. BATTLES OF PLATAEA AND MYCALE, 479 B.C. Mardonius passed the winter quietly in Thessaly, preparing for the spring campaign. The Greeks in their turn made a final effort. A strong Spartan army, supported by the Athenians and their allies, met the Persians near the little town of Plataea in Boeotia. Here the heavy-armed Greek soldiers, with their long spears, huge shields, and powerful swords, easily overcame the enormous masses of the enemy. The success at Plataea showed how superior to the Persians were the Greeks in equipment, leadership, and fighting power. At the same time as this battle the remainder of the Persian fleet suffered a crushing defeat at Mycale, a promontory off the Ionian coast. These two battles really ended the war. Never again was Persia to make a serious effort to secure dominion over Continental Greece. VICTORIUS HELLAS The Great Persian War was much more than a conflict between two rival states. It was a struggle between East and West; between Oriental despotism and Occidental individualism. On the one side were all the populous, centralized countries of Asia; on the other side, the small, disunited states of Greece. In the East was the boundless wealth, in men and money, of a world-wide empire. In the West were the feeble resources of a few petty communities. Nevertheless Greece won. The story of her victory forms an imperishable record in the annals of human freedom. 34. ATHENS UNDER THEMISTOCLES, ARISTIDES, AND CIMON THEMISTOCLES AND THE FORTIFICATIONS OF ATHENS After the battle of Plataea the Athenians, with their wives and children, returned to Attica and began the restoration of their city, which the Persians had burned. Their first care was to raise a wall so high and strong Athens in future would be impregnable to attack. Upon the suggestion of Themistocles it was decided to include within the fortifications a wide area where all the country people, in case of another invasion, could find a refuge. Themistocles also persuaded the Athenians to build a massive wall on the land side of Piraeus, the port of Athens. That harbor town now became the center of Athenian industry and commerce.
