5. Nearchus says, that while Alexander was on his march, he himself commenced his voyage, in the autumn, about the achronical rising of the Pleiades,[418] the wind not being before favourable. The Barbarians however, taking courage at the departure of the king, became daring, and attempted to throw off their subjection, attacked them, and endeavoured to drive them out of the country. But Craterus set out from the Hydaspes, and proceeded through the country of the Arachoti and of the Drangæ into Carmania. Alexander was greatly distressed throughout the whole march, as his road lay through a barren country. The supplies of provisions which he obtained came from a distance, and were scanty and unfrequent, so much so that the army suffered greatly from hunger, the beasts of burden dropped down, and the baggage was abandoned, both on the march and in the camp. The army was saved by eating dates and the marrow of the palm-tree.[419] Alexander however (says Nearchus), although acquainted with the hardships of the enterprise, was ambitious of conducting this large army in safety, as a conqueror, through the same country where, according to the prevailing report, Semiramis escaped by flight from India with about twenty, and Cyrus with about seven men. 6. Besides the want of provisions, the scorching heat was distressing, as also the deep and burning sand. In some places there were sand-hills, so that in addition to the difficulty of lifting the legs, as out of a pit, there were ascents and descents. It was necessary also, on account of the watering places, to make long marches of two, four, and sometimes even of six hundred stadia, for the most part during the night. Frequently the encampment was at a distance of 30 stadia from the watering places, in order that the soldiers might not be induced by thirst to drink to excess. For many of them plunged into the water in their armour, and continued drinking until they were drowned; when swollen after death they floated, and corrupted the shallow water of the cisterns. Others, exhausted by thirst, lay exposed to the sun, in the middle of the road. They then became tremulous, their hands and their feet shook, and they died like persons seized with cold and shivering. Some turned out of the road to indulge in sleep, overcome with drowsiness and fatigue; some were left behind, and perished, being ignorant of the road, destitute of everything, and overpowered by heat. Others escaped after great sufferings. A torrent of water, which fell in the night time, overwhelmed and destroyed many persons, and much baggage; a great part even of the royal equipage was swept away.
