The first part of his vow was easily kept, for his troops soon defeated the Ionian army, and forced the rebels to obey him once more. When Darius heard this, he was very much pleased; and then, sending for his bow, he shot an arrow in the direction of Athens, to show that the punishment of the Athenians would be his next care.
As he was afraid of forgetting these enemies in the pressure of other business, he gave orders that a slave should appear before him every day while he sat at dinner, and solemnly say, "Master, remember the Athenians!"
When the preparations for this distant war were ended, the Persian army set out for Greece. In order to reach that country, it had to march a long way through the northern part of Asia Minor, cross a narrow strait called the Hel´les-pont, and pass along the coast of the Ægean Sea, through Thrace and Scyth´i-a.
In these countries the Persian army met the fierce and warlike Scyth´i-ans mounted on their fleet-footed horses, and was nearly cut to pieces. The Persians were so frightened by the attack of these foes, that they refused to go any farther, and even beat a hasty retreat.
The Persian fleet in the mean while had sailed along bravely. It soon came to the promontory formed by Mount A´thos, a tall mountain which sometimes casts a shadow eighty miles long over the sea. Here a terrible tempest overtook the fleet, and the waves rose so high that six hundred vessels were dashed to pieces.
All the rest of the Persian vessels were so damaged by the storm, that it was soon decided that they had better return home. The soldiers of The Great King were of course greatly discouraged by these misfortunes; but Darius was more than ever determined to conquer Greece, and at once began to gather a second army and to build a second fleet.
XLIII. THE ADVANCE OF THE SECOND HOST.
Darius was very busy preparing this other army to march against Greece. While the men were being drilled, he sent two messengers to the Greek towns and islands, bidding them surrender and give him earth and water.
