But the Gods of High Olympus watched over their children and when the Phœnician fleet carrying the Persian troops was near Mount Athos, the Storm-God blew his cheeks until he almost burst the veins of his brow, and the fleet was destroyed by a terrible hurricane and the Persians were all drowned. [Illustration: THE BATTLE OF MARATHON] Two years later more Persians came. This time they sailed across the Ægean Sea and landed near the village of Marathon. As soon as the Athenians heard this they sent their army of ten thousand men to guard the hills that surrounded the Marathonian plain. At the same time they despatched a fast runner to Sparta to ask for help. But Sparta was envious of the fame of Athens and refused to come to her assistance. The other Greek cities followed her example with the exception of tiny Plataea which sent a thousand men. On the twelfth of September of the year 490, Miltiades, the Athenian commander, threw this little army against the hordes of the Persians. The Greeks broke through the Persian barrage of arrows and their spears caused terrible havoc among the disorganised Asiatic troops who had never been called upon to resist such an enemy. That night the people of Athens watched the sky grow red with the flames of burning ships. Anxiously they waited for news. At last a little cloud of dust appeared upon the road that led to the North. It was Pheidippides, the runner. He stumbled and gasped for his end was near. Only a few days before had he returned from his errand to Sparta. He had hastened to join Miltiades. That morning he had taken part in the attack and later he had volunteered to carry the news of victory to his beloved city. The people saw him fall and they rushed forward to support him. “We have won,” he whispered and then he died, a glorious death which made him envied of all men. As for the Persians, they tried, after this defeat, to land near Athens but they found the coast guarded and disappeared, and once more the land of Hellas was at peace. Eight years they waited and during this time the Greeks were not idle. They knew that a final attack was to be expected but they did not agree upon the best way to avert the danger. Some people wanted to increase the army. Others said that a strong fleet was necessary for success. The two parties led by Aristides (for the army) and Themistocles (the leader of the bigger-navy men) fought each other bitterly and nothing was done until Aristides was exiled. Then Themistocles had his chance and he built all the ships he could and turned the Piræus into a strong naval base. In the year 481 B.C. a tremendous Persian army appeared in Thessaly, a province of northern Greece. In this hour of danger, Sparta, the great military city of Greece, was elected commander-in-chief. But the Spartans cared little what happened to northern Greece provided their own country was not invaded. They neglected to fortify the passes that led into Greece. [Illustration: THERMOPYLAE]
