Thus, therefore, the Athenians completed their wall, and commenced their other buildings immediately after the retreat of the Mede.
Meanwhile Pausanias, son of Cleombrotus, was sent out from Lacedaemon as commander-in-chief of the Hellenes, with twenty ships from Peloponnese.
With him sailed the Athenians with thirty ships, and a number of the other allies.

They made an expedition against Cyprus and subdued most of the island, and afterwards against Byzantium, which was in the hands of the Medes, and compelled it to surrender.

This event took place while the Spartans were still supreme.

But the violence of Pausanias had already begun to be disagreeable to the Hellenes, particularly to the Ionians and the newly liberated populations.

These resorted to the Athenians and requested them as their kinsmen to become their leaders, and to stop any attempt at violence on the part of Pausanias.
