The Spartans not only gave way, but when an Athenian fleet set sail for the Hellespont, the Spartans sent twenty ships with Pausanias, the general who had commanded at Plataea, to join the {175} expedition. The combined fleets took Sestos and then in the following year Byzantium. Pausanias was left in command at Byzantium, and soon after a strange change was observed in him. His manner became overbearing and proud, and he gave up his Spartan habits of simple living, and adopted Persian ways, even dressing as a Persian. All this was so suspicious that he was recalled to Sparta, but as nothing was proved against him, he returned to Byzantium. Here he entered into correspondence with Xerxes and offered, in return for gold and the Great King's daughter as his bride, to betray Greece to the Persians. Though this was not known in Sparta till later, his conduct became sufficiently suspicious for the Spartans to recall him a second time, but at first they could find no definite proofs of his treachery. At last one of his slaves gave evidence against him. For some time Pausanias had been sending messengers to Asia Minor, and this particular slave had noticed that none of these messengers ever returned. When in time it became his turn to be sent, instead of bearing the message to the East, he took it to one of the Ephors, who opened it and found in it proofs of treachery and betrayal of Greece to the Barbarian, with instructions to kill the slave who brought the message. The news that his messenger had been intercepted reached Pausanias, who immediately fled from his house and took refuge in a chamber adjoining the shrine in one of the temples. Here he was secure, but the Ephors, in order to prevent his escape, gave orders that the doorway should be blocked up, and, imprisoned in the little chamber, {176} Pausanias slowly starved to death. He was only taken out when he was just at the point of death, in order that the body of a traitor might not profane the temple.
