Their defensive armor consisted of a bright helmet, adorned with plumes, and covering the head, a strong corslet defending the breast, greaves of brass decending the leg to the feet, and an ample shield, loosely attached to the left shoulder and arm, which turned in all directions, and opposed its firm resistance to every hostile assault. With men thus organized and accoutred, a battle consisted of so many duels, and the combatants fought with all the keenness of personal resentment. The slaughter in such engagements was correspondingly great, the fight seldom terminating till one of the parties was nearly destroyed, or at least greatly reduced in numbers. It was a people so animated and prepared that the hosts of Persia were about to encounter. Compelled to meet the invaders unassisted, the Athenians were able to march an army of only 9000 men, exclusive of about as many light-armed slaves, into the field. With Miltiades as their leader and commander-in-chief, they met the Persians in battle on the plain of Marathon, thirty miles from Athens, and by great skill and courage, and the force of their close phalanx of spearmen, completely conquered them. Upwards of 6000 Persians were slain on the field, while the number killed of the Athenians was but 192. This is reckoned by historians one of the most important victories in ancient times, for it saved the independence of the whole of Greece. To the disgrace of the fickle Athenians, they afterwards showed the greatest ingratitude to Miltiades, and put him in prison on a charge of favoring the Persians. He died there the year after his great victory. Soon after, the citizens of Athens, on a plea equally unfounded, banished Aristides, an able leader of the aristocratic party in the state, and who, from his strict integrity and wisdom, was usually entitled ‘Aristides the Just.’ On the banishment of this eminent individual, Themistocles, a person who was more democratic in his sentiments, became the leader of the councils of the Athenians. Meanwhile the Grecian liberties were again menaced by the Persians. Xerxes, son of Darius, marched an army across the Hellespont by a bridge of boats from the Asiatic shore, and led it towards the southern part of Greece. The utmost force that the confederate Greeks could oppose to the countless host of Persians, did not exceed 60,000 men. Of these, a band of Spartans, numbering 8,000 soldiers, under Leonidas their king, was posted at the pass of Thermopylae, to intercept the enemy, and here they discomfited every successive column of the Persians as it entered the defile. Ultimately, foreseeing certain destruction, Leonidas commanded all to retire but 300, with whom he proposed to give the Persians some idea of what the Greeks could submit to for the sake of their country. He and his 300 were cut off to a man. Xerxes took possession of Attica and Athens, but in the naval battle with the Athenian fleet at Salamis, which occurred soon after [October 20, 480 B.
