began to carry out Alexander’s instructions in regard to bridging it. Alexander then appointed Nicanor, one of the Companions, viceroy of the land on this side the river Indus; and in the first place leading his army towards that river, he brought over on terms of capitulation the city of Peucelaotis, which was situated not far from it. In this city he placed a garrison of Macedonians, under the command of Philip, and then reduced to subjection some other small towns situated near the same river, being accompanied by Cophaeus and Assagetes, the chieftains of the land. Arriving at the city of Embolima,[616] which was situated near the rock Aornus, he left Craterus there with a part of the army, to gather as much corn as possible into the city, as well as all the other things requisite for a long stay, so that making this their base of operations, the Macedonians might be able by a long siege to wear out the men who were holding the rock, supposing it were not captured at the first assault. He then took the bowmen, the Agrianians, and the brigade of Coenus, and selecting the lightest as well as the best-armed men from the rest of the phalanx, with 200 of the Companion cavalry and 100 horse-bowmen, he advanced to the rock. This day he encamped where it appeared to him convenient; but on the morrow he approached a little nearer to the rock, and encamped again. CHAPTER XXIX. SIEGE OF AORNUS. At this juncture some of the natives came to him, and surrendering themselves, offered to lead him to the part of the rock where it could be most easily assailed, and from which it would be easy for him to capture the place. With these he sent Ptolemy, son of Lagus, the confidential body-guard, in command of the Agrianians and the other light-armed troops, together with picked men from the shield-bearing guards. He gave this officer instructions, as soon as he had got possession of the place, to occupy it with a strong guard, and signal to him that it was held. Ptolemy proceeded along a road which was rough and difficult to pass, and occupied the position without the knowledge of the barbarians. After strengthening his position with a stockade and a ditch all round, he raised a beacon from the mountain, whence it was likely to be seen by Alexander. The flame was at once seen, and on the following day the king led his army forward; but as the barbarians disputed his advance, he could do nothing further on account of the difficult nature of the ground. When the barbarians perceived that Alexander could not make an assault, they turned round and attacked Ptolemy, and a sharp battle ensued between them and the Macedonians, the Indians making great efforts to demolish the stockade, and Ptolemy to preserve his position. But the barbarians, getting the worst of it in the skirmish, withdrew as the night came on. Alexander now selected from the Indian deserters a man who was not only devoted to him but
