32. Sending his fleet through the Euxine Sea into the Danube, with orders to make a bridge of boats two days’ journey from its mouth, Darius marched through Thrace, receiving or compelling the submission of its tribes, and adding their young men to his army. Arriving at the Danube, he crossed the bridge and gave orders to the Greeks to remain and guard it sixty days; if in that time he did not return, they might conclude that he had gone to Media by another route. The details of the great king’s operations north of the Danube are unknown to history. There were no great cities to take; the wandering Scythians destroyed their scanty harvests, stopped their wells, removed their families northward to places of security, and drew the invader after them into the depths of their forests or uninhabited deserts.
Unable to bring his enemy to battle, and seeing his army reduced to great distress for want of food and water, Darius was compelled to retreat by the way he had come. The sixty days were more than elapsed when a Scythian force, which had been watching his movements, hastened to the Danube by a shorter route, urging the Ionians, who were still on guard, to destroy the bridge and leave Darius to perish, like Cyrus, in the northern deserts. The Greeks of Asia might thus have gained their freedom without a blow; but the tyrants who commanded the fleet had interests of their own quite separate from those of their people. Histiæ´us of Mile´tus urged upon his fellow-despots that their power must fall with that of Darius, being sustained by him against the popular will. His arguments prevailed, and the great king, arriving in the darkness of midnight, closely pursued by the Scythians, was able to repass the river in safety.
33. Histiæus was rewarded by a grant of land on the river Stry´mon, including the town of Myrci´nus, for the site of a colony. With its fertile soil, ample forests, convenience for commerce, and neighboring mines of gold and silver, this new domain immediately attracted settlers and became an important maritime station. Its rapid growth, indeed, excited the fears of Darius, lest its owner might become too powerful for a vassal, and interpose a barrier between himself and the Greeks. He sent for Histiæus, whom he treated with every mark of respect, and pretending that he could not do without his valuable counsels, kept him constantly within reach at the court of Susa. Histiæus, resolved to break his golden chains at any cost, sent a singular epistle to his cousin, Aristag´oras, whom he had left as his lieutenant at Miletus, commanding him to stir up a revolt among the Asiatic Greeks.
34. The Ionian cities, extending ninety miles along the coast in an almost unbroken line of magnificent quays, warehouses, and dwellings, were so important to the empire, on account of the fleets which they could furnish, that they had been left in greater freedom than any other conquered territory. Instead of satraps, they were governed by their own magistrates—either a single tyrant in each city or a council of nobles, called an oligarchy—but always in the Persian interest. The European Greeks were stirred by a desire to liberate their brethren in Asia, and this afforded a constant pretext for a Persian war. The forces of Athens and Ere´tria were now added to those of Aristagoras, who had, moreover, strengthened his cause by abdicating his tyranny, and aiding the other cities to assume the same free and popular government which he established at Miletus. The tyrants were every-where expelled, and the people sprang to arms.
From Eph´esus the united forces marched up the valley of the Cay´ster, and swiftly crossing the mountains, took Sardis by surprise. The city was easily captured, but Ar´tapher´nes, the satrap, retired with a strong garrison to the castle, which, from its inaccessible rock, defied assault. A spark falling on the light reeds which formed the roofs of Sardis set fire to the town, and the invaders were compelled to retire. They were pursued and defeated with great loss by Artaphernes, in the battle of Ephesus. The Athenians now withdrew, but the war went on with undiminished spirit. The inhabitants of Cyprus, the Carians and Caunians of the south-western corner of the peninsula made common cause with the Ionian, Æo´lian, and Hellespontine Greeks; Byzantium was taken, and the whole coast from the Thracian Bosphorus to the Gulf of Issus was for the moment free from Persian dominion. The brave Carians, though twice defeated with great loss, were victorious in a third battle, where a son-in-law of Darius was slain. But the power of the great king was at length triumphant. The fleet of the Ionians was defeated near Miletus, and the vengeance of the Persians was concentrated on this devoted city, the leader of the rebellion. After a long blockade, it was taken by storm in the sixth year of the revolt.
35. The honor of the great king was now engaged to the punishment of those European Greeks who had intermeddled between himself and his subjects. It was the first time that the Athenians had come to the notice of Darius. He inquired who and what sort of men they were, and being told, he seized his bow and shot an arrow into the air, crying aloud, “O Supreme God, grant that I may avenge myself on the Athenians!” From that time a servant was instructed to say to him three times every day as he sat at table, “Sire, remember the Athenians!”
36. In the spring of 492 B. C., a great force was intrusted for this purpose to Mardo´nius, son-in-law of Darius. Its immediate design failed, for the fleet was shattered at Mount Athos, and the army nearly destroyed by the Brygians, a Thracian tribe. Thasos, however, was captured, and Macedonia was subjected to Persia.
37. B. C. 490. A second great expedition, two years later, was conducted by Datis, accompanied by Artaphernes, son of the former satrap of that name, and nephew of the king. Having passed the sea, they fell first upon Eretria, which was taken by treachery, its temples burnt, and its inhabitants bound in chains for transportation to Asia. The first decisive trial of strength between Persia and the western Greeks took place at Mar´athon, in Attica. The Persians numbered 100,000 men, the Greeks but little more than 10,000. The Medo-Persian troops had hitherto been considered invincible; but that magnificent soldiery was now, to a certain extent, replaced by unwilling conscripts from conquered tribes, who marched, dug, or fought under the lash of overseers. Miltiades, who, as prince of the Chersonesus, had served in the Persian armies, well knew this element of weakness, and it was with just confidence in the superiority of his free Athenians that he gave orders for the battle.
38. In the center, where the native Persians fought, they gained the advantage, and pursued the Athenians up one or two of the valleys which surround the base of Mount Kotro´ni; but, at the same time, both the right and left of the Asiatics were defeated by the Greeks, who, instead of pursuing, united their forces on the field to the relief of their center, and thus gained a complete victory. The Persians fled to their ships, now fiercely followed by the Greeks, and a still more furious contest ensued at the water’s edge. The Athenians sought to fire the fleet, but seven galleys only were destroyed; the rest, with the shattered remains of the army, made good their escape.
39. The Persian commander did not lose his spirit in defeat. Encouraged by a preconcerted signal of the partisans of Hip´pias, he sailed immediately around Attica, hoping to surprise Athens in the absence of its defenders. But Miltiades, too, had seen the glittering shield raised upon a mountain-top, and guessed its meaning. Leaving Aristi´des with one tribe to guard the spoils of the battle-field, he led his army by a rapid night-march across the country to Athens. When Datis, the next morning, having doubled the point of Su´nium, sailed up the Athenian harbor, he saw upon the heights above the city the same victorious troops from whom his men had fled the evening before. He made no attempt to land, but sailed away with his Eretrian prisoners to the coasts of Asia.
