History of the Peloponnesian War

Such were the words of the Thebans. The Lacedaemonian judges decided that the question, whether they had received any service from the Plataeans in the war, was a fair one for them to put; as they had always invited them to be neutral, agreeably to the original covenant of Pausanias after the defeat of the Mede, and had again definitely offered them the same conditions before the blockade. This offer having been refused, they were now, they conceived, by the loyalty of their intention released from their covenant; and having, as they considered, suffered evil at the hands of the Plataeans, they brought them in again one by one and asked each of them the same question, that is to say, whether they had done the Lacedaemonians and allies any service in the war; and upon their saying that they had not, took them out and slew them all without exception.

The number of Plataeans thus massacred was not less than two hundred, with twenty-five Athenians who had shared in the siege. The women were taken as slaves.

The city the Thebans gave for about a year to some political emigrants from Megara, and to the surviving Plataeans of their own party to inhabit, and afterwards razed it to the ground from the very foundations, and built on to the precinct of Hera an inn two hundred feet square, with rooms all round above and below, making use for this purpose of the roofs and doors of the Plataeans: of the rest of the materials in the wall, the brass and the iron, they made couches which they dedicated to Hera, for whom they also built a stone chapel of a hundred feet square. The land they confiscated and let out on a ten-years' lease to Theban occupiers.

The adverse attitude of the Lacedaemonians—in the whole Plataean affair was mainly adopted to please the Thebans, who were thought to be useful in the war at that moment raging.

Such was the end of Plataea in the ninety-third year after she became the ally of Athens.
