By this time the remaining garrison of Platæa was reduced to the last stage of weakness. The besiegers might probably long before have taken the town without difficulty by assault. But the Spartans had a motive of policy for wishing to bring the siege to a different termination. They looked forward to a peace which they might have to conclude upon the ordinary terms of a mutual restitution of conquests made in the war. In this case, if Platæa fell by storm, they would be obliged to restore it to Athens; but if it capitulated, they might allege that it was no conquest. With this view their commander protracted the blockade, until at length he discovered by a feint attack that the garrison was utterly unable to defend the walls. He then sent a herald to propose that they should surrender, not to the Thebans, but to the Spartans, on condition that Spartan judges alone should decide upon their fate. These terms were accepted, the town delivered up, and the garrison, which was nearly starved, received a supply of food. In a few days five commissioners came from Sparta to hold the promised trial. But instead of the usual forms of accusation and defence, the prisoners found themselves called upon to answer a single question: Whether in the course of the war they had done any service to Sparta and her allies. The spirit which dictated such an interrogatory was clear enough. The prisoners however obtained leave to plead for themselves without restriction; their defence was conducted by two of their number, one of whom, Lacon son of Aimnestus, was
The arguments of the Platæan orators, as reported by Thucydides, are strong, and the address which he attributes to them is the only specimen he has left of pathetic eloquence. They could point out the absurdity of sending five commissioners from Sparta, to inquire whether the garrison of a besieged town were friends of the besiegers; a question which, if retorted upon the party which asked it, would equally convict them of a wanton aggression. They could appeal to their services and sufferings in the Persian War, when they alone among the Bœotians remained constant to the cause of Greece, while the Thebans had fought on the side of the barbarians in the very land which they now hoped to make their own with the consent of Sparta. They could plead an important obligation which they had more recently conferred on Sparta herself, whom they had succoured with a third part of their whole force, when her very existence was threatened by the revolt of the Messenians after the great earthquake. They could urge that their alliance with Athens had been originally formed with the approbation, and even by the advice, of the Spartans themselves; that justice and honour forbade them to renounce a connection which they had sought as a favour, and from which they had derived great advantages; and that, as far as lay in themselves, they had not broken the last peace, but had been treacherously surprised by the Thebans, while they thought themselves secure in the faith of treaties. Even if their former merits were not sufficient to outweigh any later offence which could be imputed to them, they might insist on the Greek usage of war, which forbade proceeding to the last extremity with an enemy who had voluntarily surrendered himself; and as they had proved, by the patience with which they had endured the torments of hunger, that they preferred perishing by famine to falling into the hands of the Thebans, they had a right to demand that they should not be placed in a worse condition by their own act, but if they were to gain nothing by their capitulation, should be restored to the state in which they were when they made it.
