THE RESCUE OF THEBES. 247 stroyed, and its defenders murdered, by a Spartan army. But it is well to say here that Thebans formed the most fiercely hostile part of that army, and that it was the Thebans who demanded and obtained the murder in cold blood of the hapless prisoners. And now we pass on to a date less than fifty years later to find a remarkable change in the state of affairs. Athens has fallen from her high estate. Sparta is now the lord and master of the Grecian world. And a harsh master has she proved, with her controlling agents in every city, her voice the arbiter in all political concerns. Thebes is now the friend of Athens and the foe of Sparta, the chief among those cities which oppose the new order of things. Yet Thebes in 379 B.c. lies hard and fast within the Spartan clutch. How she got there is now for us to tell. It was an act of treason, some three years before, that handed this city over to the tender mercies of her old ally, her present foe. There was a party in Thebes favorable to Sparta, at whose head was a man named Leontiades. And at this time Sparta was at war with Olynthus, a city far to the north. One Spartan army had marched to Olynthus.
