The site of Pattala has been usually looked for near the modern Tatta. But Dr. Kennedy, in his recent ‘Narrative of the Campaign of the Army of the Indus in Scinde and Kabool’ (ch. v. p. 104), shows some reasons for thinking that it must have been considerably higher up the river than Tatta; somewhere near Sehwan. “The delta commencing about 130 miles above the sea, its northern apex would be somewhere midway between Hyderabad and Sehwan; where local traditions still speak of ancient cities destroyed, and of greater changes having occurred than in any other part of the course of the Indus.” The constant changes in the course of the Indus, however (compare p. 73 of his work), noticed by all observers, render every attempt at such identification conjectural—see Wood’s Journey to the Oxus, p. 12. The fleet was now left to be conducted by the admiral Nearchus, from the mouth of the Indus round by the Persian Gulf to that of the Tigris: a memorable nautical enterprise in Grecian antiquity. Alexander himself (about the month of August) began his march by land westward through the territories of the Arabitæ and the Oritæ, and afterwards through the deserts of Gedrosia. Pura, the principal town of the Gedrosians, was sixty days’ march from the boundary of the Oritæ.[563] [563] Arrian, vi. 24, 2; Strabo, xv. p. 723. Here his army, though without any formidable opposing enemy, underwent the most severe and deplorable sufferings; their march being through a sandy and trackless desert, with short supplies of food and still shorter supplies of water, under a burning sun. The loss in men, horses, and baggage-cattle from thirst, fatigue, and disease was prodigious; and it required all the unconquerable energy of Alexander to bring through even the diminished number.[564] At Pura the army obtained repose and refreshment, and was enabled to march forward into Karmania, where Kraterus joined them with his division from the Indus, and Kleander with the division which had been left at Ekbatana. Kleander, accused of heinous crimes in his late command, was put to death or imprisoned: several of his comrades were executed. To recompense the soldiers for their recent distress in Gedrosia, the king conducted them for seven days in drunken bacchanalian procession through Karmania, himself and all his friends taking part in the revelry; an imitation of the jovial festivity and triumph with which the god Dionysus had marched back from the conquest of India.[565] [564] Arrian, vi. 25, 26; Curtius. ix. 10; Plutarch, Alex. 66.
