who were disappointed by his lack of decisive victory and his appointment of Peisander as navarch before the disaster of Knidos. The loss of the Spartan fleet besides allowed Konon to capture the island of Kythera, in the south of the Peloponnese, from where he could raid Spartan territory. In 392, Sparta sent Antalcidas to Asia in order to negotiate a general peace with Tiribazus, the satrap of Lydia, while Sparta would recognise Persia's sovereignty over the Asian Greek cities. However, the Greek allies also sent emissaries to Sardis to refuse Antalcidas' plan, and Artaxerxes likewise rejected it. A second peace conference in Sparta failed the following year because of Athens. A personal enemy of Antalcidas, Agesilaus likely disapproved these talks, which show that his influence at home had waned. Plutarch says that he befriended the young Agiad king Agesipolis, possibly to prevent his opponents from coalescing behind him. By 391 Agesilaus had apparently recovered his influence as he was appointed at the head of the army, while his half-brother Teleutias became navarch. The target was Argos, which had absorbed Corinth into a political union the previous year. In 390 BC he made several successful expeditions into Corinthian territory, capturing Lechaeum and Peiraion. The loss, however, of a battalion (mora), destroyed by Iphicrates, neutralised these successes, and Agesilaus returned to Sparta. In 389 BC he conducted a campaign in Acarnania, but two years later the Peace of Antalcidas, warmly supported by Agesilaus, put an end to the war, maintaining Spartan hegemony over Greece and returning the Greek cities of Asia Minor to the Achaemenid Empire. In this interval, Agesilaus declined command over Sparta's aggression on Mantineia, and justified Phoebidas' seizure of the Theban Cadmea so long as the outcome provided glory to Sparta. Decline When war broke out afresh with Thebes, Agesilaus twice invaded Boeotia (in 378 and 377 BC), although he spent the next five years largely out of action due to an unspecified but apparently grave illness. In the congress of 371 an altercation is recorded between him and the Theban general Epaminondas, and due to his influence, Thebes was peremptorily excluded from the peace, and orders given for Agesilaus's royal colleague Cleombrotus to march against Thebes in 371. Cleombrotus was defeated and killed at the Battle of Leuctra and the Spartan supremacy overthrown. In 370 Agesilaus was engaged in an embassy to Mantineia, and reassured the Spartans
