_Third Year of the War--Investment of Plataea--Naval Victories of Phormio--Thracian Irruption into Macedonia under Sitalces_ The next summer the Peloponnesians and their allies, instead of invading Attica, marched against Plataea, under the command of Archidamus, son of Zeuxidamus, king of the Lacedaemonians.

He had encamped his army and was about to lay waste the country, when the Plataeans hastened to send envoys to him, and spoke as follows: "Archidamus and Lacedaemonians, in invading the Plataean territory, you do what is wrong in itself, and worthy neither of yourselves nor of the fathers who begot you.
Pausanias, son of Cleombrotus, your countryman, after freeing Hellas from the Medes with the help of those Hellenes who were willing to undertake the risk of the battle fought near our city, offered sacrifice to Zeus the Liberator in the marketplace of Plataea, and calling all the allies together restored to the Plataeans their city and territory, and declared it independent and inviolate against aggression or conquest.
Should any such be attempted, the allies present were to help according to their power.

Your fathers rewarded us thus for the courage and patriotism that we displayed at that perilous epoch; but you do just the contrary, coming with our bitterest enemies, the Thebans, to enslave us.
We appeal, therefore, to the gods to whom the oaths were then made, to the gods of your ancestors, and lastly to those of our country, and call upon you to refrain from violating our territory or transgressing the oaths, and to let us live independent, as Pausanias decreed." The Plataeans had got thus far when they were cut short by Archidamus saying: "There is justice, Plataeans, in what you say, if you act up to your words.

According, to the grant of Pausanias, continue to be independent yourselves, and join in freeing those of your fellow countrymen who, after sharing in the perils of that period, joined in the oaths to you, and are now subject to the Athenians; for it is to free them and the rest that all this provision and war has been made.
I could wish that you would share our labours and abide by the oaths yourselves; if this is impossible, do what we have already required of you--remain neutral, enjoying your own; join neither side, but receive both as friends, neither as allies for the war.

With this we shall be satisfied." Such were the words of Archidamus.
