Xenophon, one of their leaders, has made this march of the Greeks, which is commonly known as the Retreat of the Ten Thousand, the subject of a separate work. It is one of the most famous military exploits of antiquity and sets the superiority of Greece in the most brilliant light, for the bold and successful enterprise of these ten thousand Greeks does not redound to their glory alone. It is the common possession of their age, their nation, and the culture which it had attained; and marks in the most striking fashion the contrast of the relative values of Persian and Greek civilisation and political institutions. A handful of Greeks bid splendid defiance to the sovereign of the enormous Persian empire, to the sheer bulk of his army, and to all the intrigues of his satraps. It was the victory of Greek subtlety and skill over the rigid and mechanical organisation of Persia, of Greek science over the intellectual poverty of the East, of Greek tactics over Persian confusion; finally, of a genuine sense of honour and patriotic pride over craft, cowardice, and servility. The route which the Ten Thousand took was not the same by which they had marched to Cunaxa; it lay through Mesopotamia, Media, Armenia, and along the southern shore of the Black Sea to Thrace. The valiant Greeks did not know their way through these countries; they had neither maps nor any trustworthy guide; they had to march through desert and wilderness, to cross mountains and ravines, to pass through barbarous tribes and whole provinces in arms; nevertheless they succeeded in reaching the frontier of their own land with comparatively slight loss. Soon after they had begun their march, Artaxerxes concluded a treaty with them through the mediation of the satrap Tissaphernes, who had succeeded to the satrapy of Cyrus, in virtue of which they were to be allowed to proceed home undisturbed, escorted by the latter at the head of a Persian army, and supplied with the requisite provisions by the way. But Tissaphernes kept the Greeks waiting for more than twenty days before he returned from the king’s camp, and when at length he did return and set forth with them on their way through Media, he showed himself of so suspicious a temper and fostered such constant and increasing friction between the Greek troops and his own, that at last Clearchus, the Greek commander, begged for an interview with the satrap. This was granted, and Clearchus, confiding in the honour of the hostile leader, went to the Persian camp accompanied by all the twenty-four officers who composed his military council. As soon as they reached it they were treacherously taken prisoners and their guard cut down. They were presently carried off to the royal capital and there put to death together.
