8. After a long preparation, in 490 B.C., an army of one hundred thousand men or more, under the command of Artaphernes, convoyed by a formidable fleet, invaded Greece. For a long time it met with little opposition, and city after city submitted to the overwhelming hosts of the Persian king. The approach to Athens was regarded as the final turning point of the war.
9. Artaphernes selected the Plains of Marathon, twenty-two miles to the northeast of Athens, as the place of his final landing. His forces, by the lowest estimate, consisted of one hundred and fifty thousand men, of which ten thousand were cavalry. To these were opposed the army of Athens and its allies, consisting in all of ten thousand men. The battle-ground forms an irregular crescent, six miles long and two broad in its widest part. It is bounded on one side by the sea, and on the other by a rampart of mountains. At the time of the battle the extremities of the plain were flanked by swamps, diminishing the extent of the front, and hampering the operations of the larger army. The command of the Greek army had been intrusted to ten generals, who ruled successively one day each. Themistocles, one of these generals, resigned his day in favor of Miltiades, and all the others followed his example. And so the battle was set, ten thousand Greeks, under Miltiades, against the overwhelming hosts of the enemy.
10. The Persians, confident in their numbers, erected no intrenchments. They did not dream of an attack from the little band of Greeks. There is evidence to believe that they were dissatisfied with the nature of the battle-field they had chosen, and were upon the point of embarking to land at some point nearer the city. If this was the case, they were very rudely awakened from their dream of security by the movement of the Greeks.
11. On the morning of the tenth day after leaving Athens, Miltiades drew up his army in order of battle. He was obliged to perilously weaken his center in order to confront the whole of the Persian army, so as to avoid the danger of being outflanked and surrounded. The Greeks began the battle by a furious attack along the whole line, endeavoring to close in a hand-to-hand conflict as soon as possible, so as to avoid the deadly arrows of the Persians, and to take the advantage of their heavier arms. The Persians were greatly astonished when they saw this little band rushing against them with such a headlong dash, and thought that the Greeks must have been seized with madness. The Persian general had concentrated his forces at the center, and at this part of the battle-field the fiery onset of Greeks was checked by mere weight of numbers. But at length the mighty Persian force moved irresistibly forward, forcing the Greeks slowly backward, fighting, dying, but never yielding. Soon the Greek army were cut in two, and the Persians marched proudly onward to assured victory.
12. But the battle was not yet over. The genius of Miltiades had anticipated this result. The wings of the Greek army, strengthened at the expense of the center, fell upon the weakened wings of the Persians with irresistable onset. The invaders were forced back step by step, the retreat soon changing into a wild and promiscuous rout, and two thirds of the Persian army ceased to exist as a fighting force. The victorious Greeks now turned their attention to the Persian center, falling upon its flanks with incredible fury. Surrounded on all sides, for a time the Persians maintained their old reputation as valiant soldiers, but nothing could withstand the impetuosity of the Greeks, and soon the whole of the invading hosts were in tumultuous retreat.
13. The victorious Greeks pressed rapidly forward to prevent the foe from embarking, and, if possible, to capture some of the ships. But the Persian archers held the victors in check until the flying soldiery were embarked, and the Greeks obtained possession of only seven vessels. But they were left in undisputed possession of the field of battle, the camp of the enemy, and an immense amount of treasure which had been abandoned in the precipitate flight. Six thousand four hundred Persian dead remained on the plain, while the Greek loss was one hundred and ninety-two.
14. All Athens hastened to welcome the brave soldiery. A Spartan force, on its way to join the Athenians, arrived too late to take part in the battle, and they quietly returned home. As the news spread, loud and frantic rejoicings were heard throughout Greece, and the name of Persia, so long a dread and a menace, lost much of its terrors.

15. But the battle of Marathon, and the victory of Miltiades, had a wider significance than could enter into the imaginations of then living man. It was a conflict between the barbarism of Asia and the dawning civilization of Europe, between Oriental despotism and human liberty. The victory rendered normal human growth possible, and, to use the expressive phrase of the modern poet—
"Henceforth to the sunset, unchecked on its way,
Shall liberty follow the march of the day."
