Cyrus the Younger
The Ten Thousand (, "oi Myrioi") were a force of mercenary units, mainly Greeks, employed by Cyrus the Younger to attempt to wrest the throne of the Persian Empire from his brother, Artaxerxes II. Their march to the Battle of Cunaxa and back to Greece (401–399 BC) was recorded by Xenophon, one of their leaders, in his work "Anabasis".
