The Persian Expedition of Cyrus

Anabasis is Xenophon’s most famous book. The seven-tome book of the Anabasis describes The March of the Ten Thousand and their return to Greece. Xenophon accompanied the Ten Thousand, a large army of Greek mercenaries hired by Cyrus the Younger, who intended to seize the throne of Persia from his brother, Artaxerxes II. The narration of the journey is Xenophon’s best known work, and 'one of the great adventures in human history’.
