6.5.4

προσορμίσας οὖν τῇ ἐν δεξιᾷ ὄχθῃ Ἀλέξανδρος τὸν στρατόν, ἵνα σκέπη τε ἦν τοῦ ῥοῦ καὶ προσβολὴ ταῖς ναυσὶν καί τις καὶ ἄκρα τοῦ ποταμοῦ ἐπιτηδείως ἀνεῖχεν ἐς τῶν ναυαγίων τε τὴν ξυναγωγὴν καὶ εἴ τινες ἐπʼ αὐτῶν ζῶντες ἔτι ἐφέροντο, τούτους τε διέσωσε καὶ ἐπισκευάσας τὰς πεπονηκυίας τῶν νεῶν Νέαρχον μὲν καταπλεῖν κελεύει ἔστʼ ἂν ἀφίκηται ἐπὶ τὰ ὅρια τοῦ Μαλλῶν ἔθνους, αὐτὸς δὲ τῶν βαρβάρων τῶν οὐ προσχωρούντων καταδρομὴν τῆς χώρας ποιησάμενος καὶ κωλύσας ἐπικουρῆσαι αὐτοὺς τοῖς Μαλλοῖς, οὕτω δὴ αὖθις ξυνέμιξε τῷ ναυτικῷ.

When they were not far from the meeting of the rivers, the pilots enjoined the rowers to put all their strength to the oars to clear the rapids, so that the vessels might not be caught and capsized in the eddies, but by the exertions of the rowers might overcome the whirling of the waters. The merchant vessels accordingly, if they happened to be whirled round by the current, suffered no damage from the eddy, beyond the alarm caused to the men on board, for these vessels, being of a round form, were kept upright by the current itself, and settled into the proper course. But the ships of war did not escape so unscathed from the eddying stream, for, owing to their length, they were not upheaved in the same way as the others on the seething surges, and if they had two banks of oars, the lower oars were not raised much above the level of the water. When the broad sides, therefore, of these vessels were exposed to the eddying current, their oars, if not lifted in proper time, were caught by the water and the blades snapped asunder. Many of the ships were thus damaged, and two which fell foul of each other sunk with the greater part of their crews. But when the river began to widen out, the current was no longer so rapid and dangerous, and the impetuosity of the eddies diminished. Alexander therefore brought his fleet to moorings on the right bank where there was a protection from the strength of the current and a roadstead for the ships. Here was also a headland projecting into the river which afforded facilities for collecting the wrecks and whatever living freight they brought. He saved the survivors; and when he had repaired the damaged craft, ordered Nearchos to sail downward till he reached the confines of the nation called the Malloi. He made himself an inroad into the territories of the barbarians who refused their submission, and prevented them sending succours to the Malloi. He then rejoined the fleet.
Hephaistion, Krateros, and Philippos had there already united their forces. He then transported to the other side of the river Hydaspes the elephants, the brigade of Polysperchon, the archers, and Philippos with the troops under his command, and appointed Krateros to conduct this expedition. Nearchos he despatched in command of the fleet, and instructed him to start on the voyage three days before the departure of the army. The rest of his forces he divided into three parts. Hephaistion was directed to set out five days in advance, so that if any of the enemy fled forward before the division commanded by the king in person they might be captured, when endeavouring to escape in that direction, by falling into Hephaistion's hands. He gave also a part of the army to Ptolemy, the son of Lagos, with orders to follow him three days later, so that such of the enemy as fled backward from his own troops might fall into the hands of those under Ptolemy. The detachment that marched in advance he ordered to wait until he himself should come up at the confluence of the Akesines and Hydraotes, where Krateros and Ptolemy had orders to join him with their divisions.
