"Stop, Pheidippides," he cried, and stop he did. Graciously and kindly did the god then speak to him, asking him why it was that Athens alone in Greece had built him no temple, yet he had always been and would forever be her friend. And now in her peril, he would come to her aid. He bade Pheidippides go home and tell Athens to take heart, for Pan was on her side.

If Pheidippides had run swiftly before, now he ran as if wings had been given to him. He hardly touched the earth but seemed to race through the air, and burst upon the waiting Athenians who had not dared expect him so soon, with the news that Sparta indeed had failed them, but that Pan, mighty to save, would fight for them!

But now grave news was brought: the Persians were landing in Attica. It was September of the year 490 B.C., and the hot summer days had not yet passed away. The Athenians could not wait for the Spartans, they must go out alone and meet the foe. They marched twenty-four miles in the heat over a rough and rugged road, until they reached the plain of Marathon. There they found the Persians.

Now the Persians had probably never intended to fight at Marathon. They hoped that the friends of Hippias in Athens would in the end betray the city to them, and their plan in landing where they did was to bring the Athenian army away from the city, and if possible to keep it away, until they should have received the expected signal from the traitors. The plain of Marathon is surrounded by hills except where it slopes down to the sea. The Athenians occupied the stronger and higher positions, the Persians were encamped near the sea, and their ships were anchored close to the coast. For several days the armies watched each other and waited. The Athenians counted the days until the moon should be full, when there was hope that the Spartans might come; the Persians knew that every added day gave the conspirators more time to do their treacherous work in the city. And so both sides waited.

Suddenly help came to the Athenians from an unexpected quarter, help which cheered and inspirited them. Through a cloud of dust on one of the roads leading down into the plain, they saw the gleam of spears and helmets. It could not be the Spartans, for they would not come from that direction. As the men drew nearer, they were found to be an army from Plataea, a little city in Boeotia, to which, when some years before Thebes had threatened her independence, Athens had sent succour. Now, though not thought of by the Athenians as an ally, because she was small and not powerful, she had remembered those who had befriended her in the hour of need, and had come down with all her fighting men to help Athens in her peril.

Miltiades was the Athenian general at Marathon. He knew why the Persians were waiting, and when messengers brought him word that they were embarking some of their men, knowing that this meant their intention to sail round to Athens, because the conspirators in the city were ready to act, he gave the signal to attack. There were probably two Persians to every Greek, so the Greek army had been arranged in the best way to face these odds. The centre line was thin, but the wings were very strong. On the first onslaught from the Persians this centre gave way, but the wings immediately wheeled round and attacked the Persians with such force that these gave way before them and fled down to the shore. The Greeks pursued, and there was terrific fighting and slaughter. Seven of the Persian ships were destroyed by fire, but the others escaped. The Persians fled to these remaining ships, leaving over six thousand dead on the plain and quantities of rich plunder. They set sail for Athens, and knowing that the Athenian army was still on the plain of Marathon, they hoped to find the city undefended and that the traitors would open the gates to them. But the Athenians who had won at Marathon were not going to let their city fall into the hands of the enemy, so when they saw the Persian ships setting sail, wearied as they were with the strain of battle, they marched over the twenty-four miles of rough road to the defence of their beloved city, leaving only a small force behind to guard the bodies of the slain and to prevent thieves from carrying off the plunder.

On his return from Sparta, Pheidippides had been asked what reward should be given him for the race he had run. All he asked was to be allowed to fight for Athens, and when the Persians had been driven away, then to wed the maid he loved and to dwell in his own home. It was given him as he asked. He fought in the fight at Marathon, but when the victory had been gained, one more race was asked of him. Over the rough road he ran to Athens to shout in the ears of the waiting Athenians: "Athens is saved!" But his heart could not contain such great joy, and having delivered his message, he died.

The Athenian army reached Athens before the enemy, and when in the moonlight the Persian ships sailed into the bay near Athens, there, ready to meet them, were the same men who had defeated them at Marathon earlier in the day. The Persians were not willing to meet them again so soon; they realized that they had indeed suffered grievous defeat, and commands were given for the broken army and crippled fleet to set sail for Asia.

The Spartans came as they had promised, but too late to take any part in the battle.
