Xenophon

The Anabasis by Xenophon (c. 430-c. 354 BCE) is an eyewitness account of Greek mercenaries' challenging "March Up-Country" from Babylon back to the coast of Asia Minor under Xenophon's guidance in 401 BCE, after their leader Cyrus the Younger fell in a failed campaign against his brother.
