The army moved on from Alexandria to Nicaea, where Alexander sacrificed to the Greek goddess Athena. From Nicaea he sent on a herald to the rāja of Takshaçilā and the native princes west of the Indus to meet him in the Kābul Valley. We know of one Indian chief, Çaçigupta (Sisikottos), already in the conqueror’s train. His had been probably some little hill-state on the slopes of the Hindu Kush, whence he had gone two years since, to help the Irānians in Bactria against Alexander. When their cause was lost, he had gone over to the European. Messengers now summoned the other chieftains of the lower Kābul Valley to meet their overlord. At Takshaçilā too messengers appeared with the summons. And the rāja, acting on the policy which his son had espoused so decisively, rose up to obey.
