PREPARATIONS FOR A VOYAGE DOWN THE INDUS.
Alexander now resolved to sail down the Hydaspes to the Great Sea, after he had prepared on the banks of that river many thirty-oared galleys and others with one and a half bank of oars, as well as a number of vessels for conveying horses, and all the other things requisite for the easy conveyance of an army on a river. At first he thought he had discovered the origin of the Nile, when he saw crocodiles in the river Indus, which he had seen in no other river except the Nile,[724] as well as beans growing near the banks of the Acesines of the same kind as those which the Egyptian land produces.[725] This conjecture was confirmed when he heard that the Acesines falls into the Indus. He thought the Nile rises somewhere or other in India, and after flowing through an extensive tract of desert country loses the name of Indus there; but afterwards when it begins to flow again through the inhabited land, it is called Nile both by the Aethiopians of that district and by the Egyptians, and finally empties itself into the Inner Sea.[726] In like manner Homer made the river Egypt give its name to the country of Egypt.[727] Accordingly when he wrote to Olympias about the country of India, after mentioning other things, he said that he thought he had discovered the sources of the Nile, forming his conclusions about things so great from such small and trivial premisses. However, when he had made a more careful inquiry into the facts relating to the river Indus, he learned the following details from the natives:—That the Hydaspes unites its water with the Acesines, as the latter does with the Indus, and that they both yield up their names to the Indus; that the last-named river has two mouths, through which it discharges itself into the Great Sea; but that it has no connection with the Egyptian country. He then removed from the letter to his mother the part he had written about the Nile.[728] Planning a voyage down the rivers as far as the Great Sea, he ordered ships for this purpose to be prepared for him. The crews of his ships were fully supplied from the Phoenicians, Cyprians, Carians, and Egyptians who accompanied the army.
At this time Coenus, who was one of Alexander’s most faithful Companions, fell ill and died, and the king buried him with as much magnificence as circumstances allowed. Then collecting the Companions and the Indian envoys who had come to him, he appointed Porus king of the part of India which had already been conquered, seven nations in all, containing more than 2,000 cities. After this he made the following distribution of his army.[729] With himself he placed on board the ships all the shield-bearing guards, the archers, the Agrianians, and the body-guard of cavalry.[730] Craterus led a part of the infantry and cavalry along the right bank of the Hydaspes, while along the other bank Hephaestion advanced at the head of the most numerous and efficient part of the army, including the elephants, which now numbered about 200. These generals were ordered to march as quickly as possible to the place where the palace of Sopeithes was situated,[731] and Philip, the viceroy of the country beyond the Indus[732] extending to Bactria, was ordered to follow them with his forces after an interval of three days. He sent the Nysaean cavalry back to Nysa.[733] The whole of the naval force was under the command of Nearchus; but the pilot of Alexander’s ship was Onesicritus, who, in the narrative which he composed of Alexander’s campaigns, falsely asserted that he was admiral, while in reality he was only a pilot.[734] According to Ptolemy, son of Lagus, whose statements I chiefly follow, the entire number of the ships was about eighty thirty-oared galleys; but the whole number of vessels, including the horse transports and boats, and all the other river craft, both those previously plying on the rivers and those built at that time, fell not far short of 2,000.[735]
