Meanwhile the rebels in Ithome, unable to prolong further a ten years' resistance, surrendered to Lacedaemon; the conditions being that they should depart from Peloponnese under safe conduct, and should never set foot in it again: any one who might hereafter be found there was to be the slave of his captor. It must be known that the Lacedaemonians had an old oracle from Delphi, to the effect that they should let go the suppliant of Zeus at Ithome. So they went forth with their children and their wives, and being received by Athens from the hatred that she now felt for the Lacedaemonians, were located at Naupactus, which she had lately taken from the Ozolian Locrians. The Athenians received another addition to their confederacy in the Megarians; who left the Lacedaemonian alliance, annoyed by a war about boundaries forced on them by Corinth. The Athenians occupied Megara and Pegae, and built the Megarians their long walls from the city to Nisaea, in which they placed an Athenian garrison. This was the principal cause of the Corinthians conceiving such a deadly hatred against Athens.
