If the two land-victories of Sparta were barren of results, the case was far otherwise with her naval defeat at Cnidus. That defeat was pregnant with consequences following in rapid succession, and of the most disastrous character. As with Athens at Ægospotami—the loss of her fleet, serious as that was, served only as the signal for countless following losses. Pharnabazus and Conon, with their victorious fleet, sailed from island to island, and from one continental seaport to another, in the Ægean, to expel the Lacedæmonian harmosts, and terminate the empire of Sparta. So universal was the odium which it had inspired, that the task was found easy beyond expectation. Conscious of their unpopularity, the harmosts in almost all the towns, on both sides of the Hellespont, deserted their posts and fled, on the mere news of the battle of Cnidus. Everywhere Pharnabazus and Conon found themselves received as liberators, and welcomed with presents of hospitality. They pledged themselves not to introduce any foreign force or governor, nor to fortify any separate citadel, but to guarantee to each city its own genuine autonomy. This policy was adopted by Pharnabazus at the urgent representation of Conon, who warned him that if he manifested any design of reducing the cities to subjection, he would find them all his enemies; that each of them severally would cost him a long siege; and that a combination would ultimately be formed against him. Such liberal and judicious ideas, when seen to be sincerely acted upon, produced a strong feeling of friendship and even of gratitude, so that the Lacedæmonian maritime empire was dissolved without a blow, by the almost spontaneous movements of the cities themselves. Though the victorious fleet presented itself in many different places, it was nowhere called upon to put down resistance, or to undertake a single siege. Cos, Nisyrus, Teos, Chios, Erythræ, Ephesus, Mytilene, Samos, all declared themselves independent, under the protection of the new conquerors. Pharnabazus presently disembarked at Ephesus and marched by land northward to his own satrapy, leaving a fleet of forty triremes under the command of Conon.
[394-393 B.C.]
To this general burst of anti-Spartan feeling, Abydos, on the Asiatic side of the Hellespont, formed the solitary exception; and it happened by a fortunate accident for Sparta that the able and experienced Dercyllidas was harmost in the town at the moment of the battle of Cnidus. Dercyllidas assembled the Abydenes, heartened them up against the reigning contagion, and exhorted them to earn the gratitude of Sparta by remaining faithful to her while others were falling off; assuring them that she would still be found capable of giving them protection. His exhortations were listened to with favour. Abydos remained attached to Sparta, was put in a good state of defence, and became the only harbour of safety for the fugitive harmosts out of the other cities, Asiatic and European.
Dercyllidas maintained his position effectively both at Abydos and at Sestos; defying the requisition of Pharnabazus that he should forthwith evacuate them. The satrap threatened war, and actually ravaged the lands round Abydos; but without any result. His wrath against the Lacedæmonians, already considerable, was so aggravated by disappointment when he found that he could not yet expel them from his satrapy, that he resolved to act against them with increased energy, and even to strike a blow at them near their own home. For this purpose he transmitted orders to Conon to prepare a commanding naval force for the ensuing spring, and in the meantime to keep both Abydos and Sestos under blockade.
