History of the Peloponnesian War

Now Pausanias, the son of Cleombrotus, was sent out from Lacedaemon as general of the Greeks with twenty ships from the Peloponnese; there sailed with him also the Athenians with thirty ships, and a large number of the other allies.

And they made an expedition against Cyprus, and subdued the greater part of it; and afterwards against Byzantium, of which the Medes were in possession, and reduced it during this period of his command.
