When they came near the junction of the rivers, the pilots passed on the order that the men should row as hard as possible to get out of the narrows, so that the ships might not fall into the eddies and be overturned by them, but might by the vigorous rowing overcome the whirlings of the water. Being of a round form, the merchant vessels which happened to be whirled round by the current received no damage from the eddy, but the men who were on board were thrown into disorder and fright. For being kept upright by the force of the stream itself, these vessels settled again into the onward course. But the ships of war, being long, did not emerge so scatheless from the whirling current, not being raised aloft in the same way as the others upon the plashing swell of water. These ships had two ranks of oars on each side, the lower oars being only a little out of the water. These vessels getting athwart in the eddies, their oars could not be raised aloft in proper time and were consequently caught by the water and came into collision with each other. Thus many of the ships were damaged; two indeed fell foul of each other and were destroyed, and many of those sailing in them perished.[739] But when the river widened out, there the current was no longer so rapid, and the eddies did not whirl round with so much violence. Alexander therefore moored his fleet on the right bank, where there was a protection from the force of the stream and a roadstead for the ships. A certain promontory also in the river jutted out conveniently for collecting the wrecks. He preserved the lives of the men who were still being conveyed upon them; and when he had repaired the damaged ships, he ordered Nearchus to sail down the river until he reached the confines of the nation called Mallians. He himself made an inroad into the territories of the barbarians who would not yield to him, and after preventing them from succouring the Mallians, he again formed a junction with the naval armament.[740] Hephaestion, Craterus, and Philip had already united their forces here. Alexander then transported the elephants, the brigade of Polysperchon, the horse-archers, and Philip with his army, across the river Hydaspes, and instructed Craterus to lead them. He sent Nearchus with the fleet with orders to set sail three days before the army started. He divided the rest of his army into three parts, and ordered Hephaestion to go five days in advance, so that if any should flee before the men under his own command and go rapidly forward they might fall in with Hephaestion’s brigade and thus be captured. He also gave a part of the army to Ptolemy, son of Lagus, with orders to follow him after the lapse of three days, so that all those who fled from him and turned back again might fall in with Ptolemy’s brigade. He ordered those in advance to wait, when they arrived at the confluence of the rivers Acesines and Hydraotes, until he himself came up; and he instructed
