History of the Peloponnesian War

While Agis was engaged with the Lesbians, the Chians and Erythraeans, who were also ready to revolt, applied, not to him but at Lacedaemon; where they arrived accompanied by an ambassador from Tissaphernes, the commander of King Darius, son of Artaxerxes,

in the maritime districts, who invited the Peloponnesians to come over, and promised to maintain their army. The king had lately called upon him for the tribute from his government, for which he was in arrears, being unable to raise it from the Hellenic towns by reason of the Athenians; and he therefore calculated that by weakening the Athenians he should get the tribute better paid, and should also draw the Lacedaemonians into alliance with the king; and by this means, as the king had commanded him, take alive or dead Amorges, the bastard son of Pissuthnes, who was in rebellion on the coast of Caria.

While the Chians and Tissaphernes thus joined to effect the same object, about the same time Calligeitus, son of Laophon, a Megarian, and Timagoras, son of Athenagoras, a Cyzicene, both of them exiles from their country and living at the court of Pharnabazus, son of Pharnaces, arrived at Lacedaemon upon a mission from Pharnabazus, to procure a fleet for the Hellespont; by means of which, if possible, he might himself effect the object of Tissaphernes' ambition, and cause the cities in his government to revolt from the Athenians, and so get the tribute, and by his own agency obtain for the king the alliance of the Lacedaemonians.

The emissaries of Pharnabazus and Tissaphernes treating apart, a keen competition now ensued at Lacedaemon as to whether a fleet and army should be sent first to Ionia and Chios, or to the Hellespont.
