Cyrus had considered himself as deeply wronged by his elder brother, who had thrown him into prison on the death of their father, Darius. Escaping from prison, he formed a design to wrest the throne from Artaxerxes. For this purpose he engaged the forces of Proxenus, and to this army Xenophon attached himself. The rendezvous was Sardis, from which the army marched east under the pretext of chastising the revolting mountaineers of Pisidia. Instead of attacking the Pisidians, the followers of Cyrus proceeded east through Asia and Babylonia till they met the forces of Artaxerxes at Cunaxa. A furious battle took place, and the rout of the king's army had begun when Cyrus, elated with the victory that seemed just within his grasp, challenged his brother to single combat. In the duel that ensued Cyrus was slain. Proxenus had already fallen, and the virtual command of the Greek army soon devolved upon Xenophon, who thereupon began the famous retreat.
A vivid account of battles, and of hardships endured from the cold, in the struggle through mountain snows, through almost impassable forests, and across bridgeless rivers, is given in Xenophon's Anabasis, the celebrated work, in seven books, which forms the classical narrative of the campaign and the retreat. Soon after the death of Cyrus, in September, B.C. 401, the seizure and murder of the leading Greek generals by the treacherous Persian satrap, Tissaphernes, placed the Greek army in great peril. Xenophon, who now took practical command, counselled and exhorted the surviving leaders, and on the next day the Greeks formed in a hollow square, the baggage in the centre, and began their retreat, which led them along the Tigris to the territory of the Carduchi (Kurds), through Armenia, and across Georgia, the enemy often harassing them.
At the point where the climax of the story, which is presented here, may be said to begin, the Greeks have entered Armenia, passed the sources of the Tigris, and reached the Teleboas. Having made a treaty with Tiribazus, governor of the province, and discovered his insincerity, and that he was ready to attack them in their passage over the mountains, they resolved upon a quick resumption of their march.
When, in the fifth month of the retreat the Greeks at last from a hilltop beheld the Euxine, they sent up a cry, "The sea! the sea!" which has echoed through succeeding ages as one of the great historic jubilations of humanity. At the end of the retreat their numbers were reduced to about six thousand, and from the starting-point at Cunaxa to the middle of the southern coast of the Black Sea they had travelled as much as two thousand miles. From Ephesus to Cunaxa and thence to the Black Sea region they had marched in fifteen months (February, B.C. 401, to June, 400), and nine months more passed before they joined the Spartan army in Asia Minor, and their task was fully accomplished. Their great performance is regarded as having prepared the way for Alexander's triumphant advances in the East. The young conqueror, on the eve of the battle of Issus, declared that he owed inspiration to the feat of the Ten Thousand.
It was thought necessary to march away as fast as possible, before the enemy's force should be reassembled, and get possession of the pass.
Collecting their baggage at once, therefore, they set forward through a deep snow, taking with them several guides, and, having the same day passed the height on which Tiribazus had intended to attack them, they encamped. Hence they proceeded three days' journey through a desert tract of country, a distance of fifteen parasangs, to the river Euphrates, and passed it without being wet higher than the middle. The sources of the river were said not to be far off. From hence they advanced three days' march, through much snow and a level plain, a distance of fifteen parasangs; the third day's march was extremely troublesome, as the north wind blew full in their faces, completely parching up everything and benumbing the men. One of the augurs, in consequence, advised that they should sacrifice to the wind, and a sacrifice was accordingly offered, when the vehemence of the wind appeared to everyone manifestly to abate. The depth of the snow was a fathom, so that many of the baggage cattle and slaves perished, with about thirty of the soldiers.
They continued to burn fires through the whole night, for there was plenty of wood at the place of encampment. But those who came up late could get no wood; those, therefore, who had arrived before and had kindled fires would not admit the late comers to the fire unless they gave them a share of the corn or other provisions that they had brought. Thus they shared with each other what they respectively had. In the places where the fires were made, as the snow melted, there were formed large pits that reached down to the ground, and here there was accordingly opportunity to measure the depth of the snow.
From hence they marched through snow the whole of the following day, and many of the men contracted the bulimia.[[28]] Xenophon, who commanded in the rear, finding in his way such of the men as had fallen down with it, knew not what disease it was. But as one of these acquainted with it told him that they were evidently affected with bulimia, and that they would get up if they had something to eat, he went round among the baggage and wherever he saw anything eatable he gave it out, and sent such as were able to run to distribute it among those diseased, who, as soon as they had eaten, rose up and continued their march. As they proceeded, Chirisophus came, just as it grew dark, to a village, and found, at a spring in front of the rampart, some women and girls belonging to the place fetching water. The women asked them who they were, and the interpreter answered, in the Persian language, that they were people going from the king to the satrap. They replied that he was not there, but about a parasang off.
[!-- Note Anchor 28 --][Footnote 28: Spelman quotes a description of the bulimia from Galen, in which it is said to be "a disease in which the patient frequently craves for food, loses the use of his limbs, falls down, turns pale, feels his extremities become cold, his stomach oppressed, and his pulse feeble." Here, however, it seems to mean little more than a faintness from long fasting.]
However, as it was late, they went with the water-carriers within the rampart, to the head man of the village, and here Chirisophus and as many of the troops as could come up encamped; but of the rest, such as were unable to get to the end of the journey spent the night on the way without food or fire, and some of the soldiers lost their lives on that occasion. Some of the enemy too, who had collected themselves into a body, pursued our rear, and seized any of the baggage-cattle that were unable to proceed, fighting with one another for the possession of them. Such of the soldiers also as had lost their sight from the effects of the snow, or had their toes mortified by the cold, were left behind. It was found to be a relief to the eyes against the snow, if the soldiers kept something black before them on the march, and to the feet, if they kept constantly in motion, and allowed themselves no rest, and if they took off their shoes in the night. But as to such as slept with their shoes on, the straps worked into their feet, and the soles were frozen about them, for when their old shoes had failed them, shoes of raw hides had been made by the men themselves from the newly skinned oxen.
