When day dawned the Persians saw with surprise that their foes had disappeared. The Spartans alone, detained by the obstinacy of Amompharetus, were still in sight. Filled with extravagant confidence at this seeming flight. Mardonius gave orders for hasty pursuit, crying to a Greek ally, "There go your boasted Spartans, showing, by a barefaced flight, what they are really worth."
Crossing the shallow stream, the Persians ran after the Greeks at full speed, without a thought of order or discipline. The foe seemed to them in full retreat, and shouts of victory rang from their lips as they rushed pell-mell across the plain.
The Spartans were quickly overtaken, and found themselves hotly assailed. They sent in haste to the Athenians for aid. The Athenians rushed forward, but soon found themselves confronted by the Greek allies of Persia, and with enough to do to defend themselves. The remainder of the Greek army had retreated to Platæa and took no part in the battle.
The Persians, thrusting the spiked extremities of their long shields in the ground, formed a breastwork from which they poured showers of arrows on the Spartan ranks, by which many were wounded or slain. Yet, despite their distress, Pausanias would not give the order to charge. He was at the old work again, offering sacrifices while his men fell around him. The responses were unfavorable, and he would not fight.
At length the victims showed favorable signs. "Charge!" was the word. With the fury of unchained lions the impatient hoplites sprang forward, and like an avalanche the serried Spartan line fell on the foe.
Down went the breastwork of shields. Down went hundreds of Persians before the close array and the long spears of the Spartans. Broken and disordered, the Persians fought bravely, doing their utmost to get to close quarters with their foes. Mardonius, mounted on a white horse, and attended by a body-guard of a thousand select troops, was among the foremost warriors, and his followers distinguished themselves by their courage.
At length the spear of Aeimnestus, a distinguished Spartan, brought Mardonius dead to the ground. His guards fell in multitudes around his body. The other Persians, worn out with the hopeless effort to break the Spartan phalanx, and losing heart at the death of their general, turned and fled to their fortified camp. At the same time the Theban allies of Persia, whom the Athenians had been fighting, gave ground, and began a retreat, which was not ended till they reached the walls of Thebes.
On rushed the victorious Spartans to the Persian camp, which they at once assailed. Here they had no success till the Athenians came to their aid, when the walls were stormed and the defenders slain in such hosts that, if we can believe Herodotus, only three thousand out of the three hundred thousand of the army of Mardonius remained alive. It is true that one body of forty thousand men, under Artabazus, had been too late on the field to take part in the fight. The Persians were already defeated when these troops came in sight, and they turned and marched away for the Hellespont, leaving the defeated host to shift for itself. Of the Greeks, Plutarch tells us that the total loss in the battle was thirteen hundred and sixty men.
The spoil found in the Persian camp was rich and varied. It included money and ornaments of gold and silver, carpets, splendid arms and clothing, horses, camels, and other valuable materials. This was divided among the victors, a tenth of the golden spoil being reserved for the Delphian shrine, and wrought into a golden tripod, which was placed on a column formed of three twisted bronze serpents. This defeat was the salvation of Greece. No Persian army ever again set foot on European soil. And, by a striking coincidence, on the same day that the battle of Platæa was fought, the Grecian fleet won a brilliant victory at Mycale, in Asia Minor, and freed the Ionian cities from Persian rule. In Greece, Thebes was punished for aiding the Persians. Byzantium (now Constantinople) was captured by Pausanias, and the great cables of the bridge of Xerxes were brought home in triumph by the Greeks.
We have but one more incident to tell. The war tent of Xerxes had been left to Mardonius, and on taking the Persian camp Pausanias saw it with its colored hangings and its gold and silver adornments, and gave orders to the cooks that they should prepare him such a feast as they were used to do for their lord. On seeing the splendid banquet, he ordered that a Spartan supper should be prepared. With a hearty laugh at the contrast he said to the Greek leaders, for whom he had sent, "Behold, O Greeks, the folly of this Median captain, who, when he enjoyed such fare as this, must needs come here to rob us of our penury."
