The British schoolboy, fleshing his young teeth upon the “Anabasis” of Xenophon, struggling in a wilderness of parasangs and paradigms and puzzling out what Cheirisophos said and where they pitched camp that night, seldom realises the romantic nature of the enterprise. There was a dynastic struggle in Persia. Cyrus, a bold and able prince, was disputing the succession to the throne with the rightful successor, Artaxerxes. Knowing the weakness of his native troops, Cyrus conceived the idea of stiffening them with ten thousand hired Greeks, for by now the use of mercenaries was growing more frequent in the Greek world. These troops were mostly Spartans, their leader was Clearchus, a Spartan, and Xenophon of Athens was a volunteer under his command. They were recruited without knowing the full nature of the enterprise, and it was only when they found themselves in the heart of Asia that they learnt to their horror that the objective was the far-distant capital. At length they reached Cunaxa, near Babylon, where a mighty host opposed their advance. In the battle Cyrus was killed and the native portion of his troops fled or surrendered or were slain. But the Greeks had fought so valiantly that the victorious army of Artaxerxes did not care to attempt their capture, though the crafty Tissaphernes succeeded in assassinating their leaders and leading the army astray into the wilderness. Thus the Ten Thousand found themselves stranded in a hostile country, without generals and without guides, nearly two thousand miles from home. But being Greeks, with a proper contempt for the barbarian, they scorned to lose heart, though the chance of a safe return must have seemed hopeless. The strong political instinct of the city-state was their salvation. They resolved themselves into a wandering _polis_, held assemblies, made speeches, elected generals, with Xenophon among them, and preserved perfect self-control and discipline. So began the Catabasis, an immense and dangerous march north-westward, through the passes of the Taurus and the uplands of Armenia, fighting the wild Kurds of the hills, struggling with cold and hunger, utterly ignorant of geography except for the belief that if they went on long enough in the same direction they would some day reach the sea. Their glad cry of “Thalassa! Thalassa!” when at last they saw the shining waters of the Euxine is a cry that has echoed through the ages. Henceforth they were passing through the series of Greek colonies that fringed the south coast of the Black Sea. Though many more adventures awaited them and they were seldom very welcome visitors, yet no fewer than 6000 reached home, and, we trust, lived happily ever afterwards. Not so much the fighting as the courage of the march and the sense of discipline make this one of the finest exploits in Greek history.
