The soldiers killed many of the beasts of burden of their own accord; for when provisions were lacking, they came together, and slaughtered most of the horses and mules. They ate the flesh of these, and said that they had died of thirst or had perished from the heat. There was no one who divulged the real truth of their conduct, both on account of the men’s distress and because all alike were implicated in the same offence. What was being done had not escaped Alexander’s notice; but he saw that the best cure for the present state of affairs would be to pretend to be ignorant of it, rather than to permit it as a thing known to himself. The consequence was, that it was no longer easy to convey the soldiers who were suffering from disease, or those who were left behind on the roads on account of the heat, partly from the want of beasts of burden and partly because the men themselves were knocking the waggons to pieces, not being able to draw them on account of the depth of the sand. They did this also because in the first stages they were compelled on this account to go, not by the shortest routes, but by those which were easiest for the carriages. Thus some were left behind along the roads on account of sickness, others from fatigue or the effects of the heat, or from not being able to bear up against the drought; and there was no one either to show them the way or to remain and tend them in their sickness. For the expedition was being made with great urgency; and the care of individual persons was necessarily neglected in the zeal displayed for the safety of the army as a whole. As they generally made the marches by night, some of the men were overcome by sleep on the road; afterwards rousing up again, those who still had strength followed upon the tracks of the army; but only a few out of many overtook the main body in safety. Most of them perished in the sand, like men shipwrecked on the sea.[800] Another calamity also befell the army, which greatly distressed men, horses, and beasts of burden; for the country of the Gadrosians is supplied with rain by the periodical winds, just as that of the Indians is; not the plains of Gadrosia, but only the mountains where the clouds are carried by the wind and are dissolved into rain without passing beyond the summits of the mountains. On one occasion, when the army bivouacked, for the sake of its water, near a small brook which was a winter torrent, about the second watch of the night the brook which flowed there was suddenly swelled by the rains in the mountains which had fallen unperceived by the soldiers. The torrent advanced with so great a flood as to destroy most of the wives and children of the men who followed the army, and to sweep away all the royal baggage as well as all the beasts of burden still remaining. The soldiers, after great exertions, were hardly able to save themselves together with their weapons, many of which they lost beyond recovery.
