Then calling in the confederates they told them that for their own parts their sentence was that the Athenians had done them wrong; but yet they desired to have all their confederates called together, and then to put it to the question again that if they would, the war might be decreed by common consent.
This done, their confederates went home; and so did also afterwards the Athenians when they had dispatched the business they came about.
This decree of the assembly that the peace was broken was made in the fourteenth year of those thirty years for which a peace had been formerly concluded after the actions past in Euboea.
The Lacedaemonians gave sentence that the peace was broken and that war was to be made, not so much for the words of the confederates as for fear the Athenian greatness should still increase. For they saw that a great part of Greece was fallen already into their hands.
Now the manner how the Athenians came to the administration of those affairs by which they so raised themselves was this.
After that the Medes, overcome by sea and land, were departed, and such of them as had escaped by sea to Mycale were there also utterly overthrown, Leotychides, king of the Lacedaemonians, then commander of the Grecians at Mycale, with their confederates of Peloponnesus went home. But the Athenians with their confederates of Ionia and the Hellespont, as many as were already revolted from the king, stayed behind and besieged Sestus, holden then by the Medes; and when they had lain before it all the winter, they took it abandoned by the barbarians. And after this they set sail from the Hellespont, everyone to his own city.
