Each tribe, under the new laws, chose its own war-leader, or general, so that there were ten generals of equal power, and in war each of these was given command of the army for a day; and one of the archons, or civil heads of the state, was made general of the state, or war archon, so that there were eleven generals in all. The leading man in each tribe was usually chosen its general, and of these we have the stories of three to tell,--Miltiades, the hero of Marathon; Themistocles, who saved Greece at Salamis; and Aristides, known as "the Just." We have already told how two of these men gained great glory. We have now to tell how they gained great disgrace. Ambition, the bane of the leaders of states, led them both to ruin. Miltiades was of noble birth, and succeeded his uncle as ruler of the Chersonese country, in Thrace. Here he fell under the dominion of Persia, and here, when Darius was in Scythia, he advised that the bridge over the Danube should be destroyed. When Darius returned Miltiades had to fly for his life. He afterwards took part in the Ionic revolt, and captured from the Persians the islands of Lemnos and Imbros. But when the Ionians were once more conquered Miltiades had again to fly for his life. Darius hated him bitterly, and had given special orders for his capture. He fled with five ships, and was pursued so closely that one of them was taken. He reached Athens in safety with the rest. Not long afterwards Miltiades revenged himself on Darius for this pursuit by his great victory at Marathon, which for the time made him the idol of the state and the most admired man in all Greece. But the glory of Miltiades was quickly followed by disgrace, and the end of his career was near at hand. He was of the true soldierly temperament, stirring, ambitious, not content to rest and rust, and as a result his credit with the fickle Athenians quickly disappeared. His head seems to have been turned by his success, and he soon after asked for a fleet of seventy ships of war, to be placed under his command. He did not say where he proposed to go, but stated only that whoever should come with him would be rewarded plentifully with gold. The victor at Marathon had but to ask to obtain. The people put boundless confidence in him, and gave him the fleet without a question. And the golden prize promised brought him numbers of eager volunteers, not one of whom knew where he was going or what he was expected to do. Miltiades was in command, and where Miltiades chose to lead who could hesitate to follow? The purpose of the admiral of the fleet was soon revealed. He sailed to the island of Paros, besieged the capital, and demanded a tribute of one hundred talents. He based this claim on the pretence that the Parians had furnished a ship to the Persian fleet, but it is known that his real motive was hatred of a citizen of Paros.
