3. All allies of the Lacedaemonians outside Peloponnese shall be upon the same footing as the Lacedaemonians themselves, and the allies of the Argives shall be upon the same footing as the Argives themselves, continuing to enjoy what they possess.
4. If it shall be anywhere necessary to make an expedition in common, the Lacedaemonians and Argives shall consult upon it and decide, as may be most fair for the allies.
5. If any of the cities, whether inside or outside Peloponnese, have a question whether of frontiers or otherwise, it must be settled, but if one allied city should have a quarrel with another allied city, it must be referred to some third city thought impartial by both parties. Private citizens shall have their disputes decided according to the laws of their several countries.
The treaty and above alliance concluded, each party at once released everything whether acquired by war or otherwise, and thenceforth acting in common voted to receive neither herald nor embassy from the Athenians unless they evacuated their forts and withdrew from Peloponnese, and also to make neither peace nor war with any, except jointly. Zeal was not wanting: both parties sent envoys to the Thracian places and to Perdiccas, and persuaded the latter to join their league. Still he did not at once break off from Athens, although minded to do so upon seeing the way shown him by Argos, the original home of his family. They also renewed their old oaths with the Chalcidians and took new ones: the Argives, besides, sent ambassadors to the Athenians, bidding them evacuate the fort at Epidaurus. The Athenians, seeing their own men outnumbered by the rest of the garrison, sent Demosthenes to bring them out. This general, under colour of a gymnastic contest which he arranged on his arrival, got the rest of the garrison out of the place, and shut the gates behind them. Afterwards the Athenians renewed their treaty with the Epidaurians, and by themselves gave up the fortress.
After the defection of Argos from the league, the Mantineans, though they held out at first, in the end finding themselves powerless without the Argives, themselves too came to terms with Lacedaemon, and gave up their sovereignty over the towns. The Lacedaemonians and Argives, each a thousand strong, now took the field together, and the former first went by themselves to Sicyon and made the government there more oligarchical than before, and then both, uniting, put down the democracy at Argos and set up an oligarchy favourable to Lacedaemon. These events occurred at the close of the winter, just before spring; and the fourteenth year of the war ended. The next summer the people of Dium, in Athos, revolted from the Athenians to the Chalcidians, and the Lacedaemonians settled affairs in Achaea in a way more agreeable to the interests of their country.
Meanwhile the popular party at Argos little by little gathered new consistency and courage, and waited for the moment of the Gymnopaedic festival at Lacedaemon, and then fell upon the oligarchs. After a fight in the city, victory declared for the commons, who slew some of their opponents and banished others. The Lacedaemonians for a long while let the messages of their friends at Argos remain without effect. At last they put off the Gymnopaediae and marched to their succour, but learning at Tegea the defeat of the oligarchs, refused to go any further in spite of the entreaties of those who had escaped, and returned home and kept the festival.
Later on, envoys arrived with messages from the Argives in the town and from the exiles, when the allies were also at Sparta; and after much had been said on both sides, the Lacedaemonians decided that the party in the town had done wrong, and resolved to march against Argos, but kept delaying and putting off the matter. Meanwhile the commons at Argos, in fear of the Lacedaemonians, began again to court the Athenian alliance, which they were convinced would be of the greatest service to them; and accordingly proceeded to build long walls to the sea, in order that in case of a blockade by land; with the help of the Athenians they might have the advantage of importing what they wanted by sea. Some of the cities in Peloponnese were also privy to the building of these walls; and the Argives with all their people, women and slaves not excepted, addressed themselves to the work, while carpenters and masons came to them from Athens.
Summer was now over. The winter following the Lacedaemonians, hearing of the walls that were building, marched against Argos with their allies, the Corinthians excepted, being also not without intelligence in the city itself; Agis, son of Archidamus, their king, was in command. The intelligence which they counted upon within the town came to nothing; they however took and razed the walls which were being built, and after capturing the Argive town Hysiae and killing all the freemen that fell into their hands, went back and dispersed every man to his city. After this the Argives marched into Phlius and plundered it for harbouring their exiles, most of whom had settled there, and so returned home. The same winter the Athenians blockaded Macedonia, on the score of the league entered into by Perdiccas with the Argives and Lacedaemonians, and also of his breach of his engagements on the occasion of the expedition prepared by Athens against the Chalcidians in the direction of Thrace and against Amphipolis, under the command of Nicias, son of Niceratus, which had to be broken up mainly because of his desertion. He was therefore proclaimed an enemy. And thus the winter ended, and the fifteenth year of the war ended with it.
