Tamos (Egyptian admiral)
Tamos, or Tamos the Egyptian, was a mercenary Egyptian Admiral hired by Cyrus the Younger, during his campaign to claim the Persian Throne. It is not known if Tamos served in the entire campaign during 401 BC. Tamos led a fleet of 25 triremes as a backup to Cyrus's mercenary Ten Thousand hoplites and Persian troops.
Tamos was Cyrus's secondary admiral, his first being Pythagoras the Spartan, who led the first fleet of 35 triremes.
