Meanwhile the Lacedaemonians, to whose lot it fell to begin the work of restitution, immediately set free all the prisoners of war in their possession, and sent Ischagoras, Menas, and Philocharidas as envoys to the towns in the direction of Thrace, to order Clearidas to hand over Amphipolis to the Athenians, and the rest of their allies each to accept the treaty as it affected them. They, however, did not like its terms, and refused to accept it; Clearidas also, willing to oblige the Chalcidians, would not hand over the town, averring his inability to do so against their will. Meanwhile he hastened in person to Lacedaemon with envoys from the place, to defend his disobedience against the possible accusations of Ischagoras and his companions, and also to see whether it was too late for the agreement to be altered; and on finding the Lacedaemonians were bound, quickly set out back again with instructions from them to hand over the place, if possible, or at all events to bring out the Peloponnesians that were in it. The allies happened to be present in person at Lacedaemon, and those who had not accepted the treaty were now asked by the Lacedaemonians to adopt it. This, however, they refused to do, for the same reasons as before, unless a fairer one than the present were agreed upon; and remaining firm in their determination were dismissed by the Lacedaemonians, who now decided on forming an alliance with the Athenians, thinking that Argos, who had refused the application of Ampelidas and Lichas for a renewal of the treaty, would without Athens be no longer formidable, and that the rest of the Peloponnese would be most likely to keep quiet, if the coveted alliance of Athens were shut against them. Accordingly, after conference with the Athenian ambassadors, an alliance was agreed upon and oaths were exchanged, upon the terms following: 1. The Lacedaemonians shall be allies of the Athenians for fifty years. 2. Should any enemy invade the territory of Lacedaemon and injure the Lacedaemonians, the Athenians shall help in such way as they most effectively can, according to their power. But if the invader be gone after plundering the country, that city shall be the enemy of Lacedaemon and Athens, and shall be chastised by both, and one shall not make peace without the other. This to be honestly, loyally, and without fraud. 3.
