For the number of the ships, see Ptolemy ap. Arrian, vi. 2, 8. On seeing crocodiles in the Indus, Alexander was at first led to suppose that it was the same river as the Nile, and that he had discovered the higher course of the Nile, from whence it flowed into Egypt. This is curious, as an illustration of the geographical knowledge of the time (Arrian, vi. 1, 3). [554] Aristobulus ap. Strab. xv. p. 692. Aristobulus said that the downward voyage occupied ten months; this seems longer than the exact reality. Moreover Aristobulus said that they had no rain during all the voyage down, through all the summer months: Nearchus stated the contrary (Strabo, _l. c._). [555] Curtius, ix. 4, 15; Diodor. xvii 98. [556] Arrian, vi. 7, 8. [557] This last stronghold of the Malli is supposed, by Mr. Cunningham and others, to have been the modern city of Multan. The river Ravee or Hydraotes is said to have formerly run past the city of Multan into the Chenab or Akesines. [558] Arrian, vi. 9, 10, 11. He notices the great discrepancy in the various accounts given of this achievement and dangerous wound of Alexander. Compare Diodor. xvii. 98, 99; Curtius, ix. 4, 5; Plutarch, Alex. 63. The wound of Alexander was so severe, that he was at first reported to be dead to the great consternation and distress of the army. However, he became soon sufficiently recovered to show himself, and to receive their ardent congratulations, in the camp established at the point of junction between the Hydraotes (Ravee) and Akesines (Chenab).[559] His voyage down the river, though delayed by the care of his wound, was soon resumed and prosecuted, with the same active operations by his land-force on both sides to subjugate all the Indian tribes and cities within accessible distance. At the junction of the river Akesines (Punjnud) with the Indus, Alexander directed the foundation of a new city, with adequate docks and conveniences for ship-building, whereby he expected to command the internal navigation.[560] Having no farther occasion now for so large a land-force, he sent a large portion of it, under Kraterus, westward (seemingly through the pass now called Bolan) into Karmania.[561] He established another military and naval post at Pattala, where the Delta of the Indus divided; and he then sailed, with a portion of his fleet, down the right arm of the river to have the first sight of the Indian Ocean. The view of ebbing and flowing tide, of which none had had experience on the scale there exhibited, occasioned to all much astonishment and alarm.[562] [559] Arrian, xi. 13. [560] Arrian, xi. 15, 5. [561] Arrian, xi. 17, 6; Strabo, xv. p. 721. [562] Arrian, xi. 18, 19; Curtius, ix. 9. He reached Pattala towards the middle or end of July, περὶ κυνὸς ἐπιτολήν (Strabo, xv. p. 692).
