The History of the Peloponnesian War
The same winter the Lacedaemonian Hippocrates sailed out from Peloponnese
with ten Thurian ships under the command of Dorieus, son of Diagoras, and
two colleagues, one Laconian and one Syracusan vessel, and arrived at
Cnidus, which had already revolted at the instigation of Tissaphernes.
When their arrival was known at Miletus, orders came to them to leave half
their squadron to guard Cnidus, and with the rest to cruise round Triopium
and seize all the merchantmen arriving from Egypt. Triopium is a
promontory of Cnidus and sacred to Apollo
. This coming to the knowledge of
the Athenians, they sailed from Samos and captured the six ships on the
watch at Triopium, the crews escaping out of them.
