These exiles went to the Spartans, based at this time at Sicyon, for support, while the Athenians and Boeotians came up to support the democrats. In a night attack, the Spartans and exiles succeeded in seizing Lechaeum, Corinth's port on the Gulf of Corinth, and defeated the army that came out to challenge them the next day. The anti-Spartan allies then attempted to invest Lechaeum, but the Spartans launched an attack and drove them off. In 392 BC, the Spartans dispatched an ambassador, Antalcidas, to the satrap Tiribazus, hoping to turn the Persians against the allies by informing them of Conon's use of the Persian fleet to begin rebuilding the Athenian empire. The Athenians learned of this, and sent Conon and several others to present their case to the Persians; they also notified their allies, and Argos, Corinth, and Thebes dispatched embassies to Tiribazus. At the conference that resulted, the Spartans proposed a peace based on the independence of all states; this was rejected by the allies, as Athens wished to hold the gains it had made in the Aegean, Thebes wished to keep its control over the Boeotian league, and Argos already had designs on assimilating Corinth into its state. The conference thus failed, but Tiribazus, alarmed by Conon's actions, arrested him, and secretly provided the Spartans with money to equip a fleet. Although Conon quickly escaped, he died soon afterward. A second peace conference was held at Sparta in the same year, but the proposals made there were again rejected by the allies, both because of the implications of the autonomy principle and because the Athenians were outraged that the terms proposed would have involved abandoning the Ionian Greeks to Persia. In the wake of the unsuccessful conference in Persia, Tiribazus returned to Susa to report on events, and a new general, Struthas, was sent out to take command. Struthas pursued an anti-Spartan policy, prompting the Spartans to order their commander in the region, Thibron, to attack him. Thibron successfully ravaged Persian territory for a time, but was killed along with much of his army when Struthas ambushed one of his poorly organized raiding expeditions. Thibron was later replaced by Diphridas, who raided more successfully, securing a number of small successes and even capturing Struthas's son-in-law, but never achieved any dramatic results.
