So, when the Thebans had failed in their attempt and the Plataeans had put to death those of their number whom they had taken alive in the battle, the Lacedaemonians, without waiting now for any pretext, marched against Plataea. They ordered all the Peloponnesians with the exception of the Argives to send two-thirds of their armies from their several cities, and they sent word to all the rest of the Boeotians and the Locrians and Phocians and Malians and Oetaeans and Aenians to take the field with their entire forces.All the states mentioned were in central Greece, and belonged to the Peloponnesian confederacy.

Then they invested the walls of Plataea with a large force, and made overtures to the Plataeans on terms that, if they would surrender their city to the Lacedaemonians, they should retain their land and enjoy their property, but that they should break off their alliance with the Athenians. The Plataeans refused this offer and made answer that they would do nothing without the Athenians, whereupon the Lacedaemonians besieged them for two years, built a double wall about their city, and made repeated assaults of every conceivable sort.

When the Plataeans were quite worn out and were in want of everything, and despaired of safety, they divided themselves by lot into two groups; some of them remained and endured the siege, but the others, waiting for a night when there was rain and a heavy wind, climbed over the wall of circumvallation, unseen of the enemy, cut down the sentinels, and got safely to Athens, but in a desperate plight and beyond all expectation. As for those who remained behind, when the city was taken by storm, all who had reached manhood were killed and the women and children were made slaves—all, that is, save those who, when they saw the Lacedaemonians advancing, got secretly away to Athens.The account of the siege and fall of Plataea is given in Thuc. 2.71-78, and Thuc. 3.20-24 and Thuc. 3.52-68.
