128 HISTORICAL TALES, first was defeated by nature, the second by man. A land expedition, led by the Persian general Mar- donius, crossed the Hellespont in the year 493 B.c., proposing to march to Athens along the coast, and with orders to bring all that were left alive of its in- habitants as captives to the great king. On marched the great host, nothing doubting that Greece would fallan easy prey to their arms. Andas they marched along the land, the fleet followed them along the ad- joining sea, until the stormy and perilous promontory of Mount Athos was reached. No doubt the Greeks viewed with deep alarm this formidable progress. They had never yet directly measured arms with the Persians, and dreaded them more than, as was afterwards shown, they had reason to. But at Mount Athos the deities of the winds came to their aid. As the fleet was rounding that promontory, often fatal to mariners, a frightful hurricane swooped upon it, and destroyed three hun- dred of its ships, while no less than twenty thousand men became victims of the waves. Some of the crews reached the shores, but of these many died of cold, and others were slain and devoured by wild beasts, which roamed in numbers on that uninhabited point of land. The land army, too, lost heavily from the hurricane; and Mardonius, fearing to advance farther after this disaster, ingloriously made his way back to the Hellespont. So ended the first invasion of Greece. Three years afterwards another was made. Da- rius, indeed, first sent heralds to Grecce, demanding earth and water in token of submission to his will.
