Dercyllidas, who succeeded him, was more equal to a great and difficult command. Having already served in Asia, under Lysander, he knew the characters of the two satraps, who divided between them, in almost independent sovereignty, the dominion of the western provinces. The instructions of the ephors directed him to lead the army into Caria, the hereditary government of Tissaphernes. But the desire of revenging a disgrace he had formerly incurred, when harmost of Abydos, in consequence of an accusation from Pharnabazus, assisted at least, according to the contemporary historian, his friend, in determining him to act otherwise. He negotiated with Tissaphernes; and that dastardly satrap, ill-disposed towards Pharnabazus, and always readier for negotiation than battle, instead of exerting the great power with which he was vested for the general defence of the empire, bargained for a particular peace for his own provinces, and consented that the Grecian arms should, without opposition from him, be carried into the Bithynian satrapy. Dercyllidas, having thus provided for the safety of the rich fields of Ionia, which would otherwise have been liable, in his absence, to suffer from the Persian cavalry, hastened his march northward; and, in the length of way from Caria to the borders of Æolis, he maintained an exactness of discipline that gained him the greater credit with the allies as it was contrasted with the licentiousness from which the country had suffered while Thimbron commanded.
