The whole Persian fleet, manned by Phœnician sailors, and a huge army, under the two satraps Datis and Artaphernes, were on the opposite side of the Ægean Sea, ready to overwhelm little Attica first, and then all Greece. Nobody had yet stood firm against those all-conquering Persians, and as they came from island to island the inhabitants fled or submitted. Attica was so small as to have only 9000 fighting men to meet this host. They sent to ask the aid of the Spartans, but though these would have fought bravely, an old rule forbade them to march during the week before the full moon, and in this week Athens might be utterly ruined. Nobody did come to their help but 600 men from the very small state of Platæa, and this little army, not numbering 10,000, were encamped around the temple of Hercules, looking down upon the bay of Marathon, where lay the ships which had just landed at least 200,000 men of all the Eastern nations, and among them many of the Greeks of Asia Minor. The hills slant back so as to make a sort of horse-shoe round the bay, with about five miles of clear flat ground between them and the sea, and on this open space lay the Persians. It was the rule among the Athenians that the heads of their ten tribes should command by turns each for a day, but Aristides, the best and most high-minded of all of them, persuaded the rest to give up their turns to Miltiades, who was known to be the most skilful captain. He drew up his men in a line as broad as the whole front of the Persian army, though far less deep, and made them all come rushing down at them with even step, but at a run, shouting the war-cry, “Io pæan! Io pæan!” In the middle, where the best men of the Persians were, they stood too firm to be thus broken, but at the sides they gave way, and ran back towards the sea, or over the hills, and then Miltiades gave a signal to the two side divisions—wings, as they were called—to close up together, and crush the Persian centre. The enemy now thought of nothing but reaching their ships and putting out to sea, while the Athenians tried to seize their ships; Cynegyrus, one brave Greek, caught hold of the prow of one ship, and when the crew cut off his hand with an axe, he still clung with the other, till that too was cut off, and he sank and was drowned. The fleet still held many men, and the Athenians saw that, instead of crossing back to Asia Minor, it was sailing round the promontory of Sunium, as if to attack Athens. It was even said that a friend of Hippias had raised a shield, glittering in the sun, as a signal that all the men were away. However, Miltiades left Aristides, with his tribe of 1000 men, to guard the plain and bury the dead, and marched back over the hills with the rest to guard their homes, that same night; but the Persians must have been warned, or have changed their mind, for they sailed away for Asia; and Hippias, who seems to have been wounded in the battle, died at Lemnos.
