[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. From such unavoidable sufferings some of the soldiers were left behind, who, seeing a piece of ground of a black appearance, from the snow having disappeared there, conjectured that it must have melted, and it had in fact melted in the spot from the effect of a fountain, which was sending up vapor in a wooded hollow close at hand. Turning aside thither, they sat down and refused to proceed farther. Xenophon, who was with the rear-guard, as soon as he heard this tried to prevail on them by every art and means not to be left behind, telling them, at the same time, that the enemy were collected and pursuing them in great numbers. At last he grew angry, and they told him to kill them, as they were quite unable to go forward. He then thought it the best course to strike a terror, if possible, into the enemy that were behind, lest they should fall upon the exhausted soldiers. It was now dark, and the enemy were advancing with a great noise, quarrelling about the booty that they had taken, when such of the rear-guard as were not disabled started up and rushed toward them, while the tired men, shouting as loud as they could, clashed their spears against their shields. The enemy, struck with alarm, threw themselves among the snow into the hollow, and no one of them afterward made himself heard from any quarter.
