Lysander

Lysander ( /laɪˈsændər/ or /ˈlaɪˌsændər/; died 395 BC, Greek: Λύσανδρος, Lýsandros) was a Spartan general who commanded the Spartan fleet in the Hellespont which defeated the Athenians at Aegospotami in 405 BC. The following year, he was able to force the Athenians to capitulate, bringing the Peloponnesian War to an end; he organized the dominion of Sparta over Greece in the last decade of his life.
