Xenophon's Anabasis, and the March of the Ten Thousand
VDH has a nice piece on Xenophon's report of the adventures and misadventures of the Greek mercenaries who were hired by Cyrus in 401 BC to remove his brother, Artaxerxes, from power in Persia.
Also, because of our appreciation of VDH, a free ad for his new book on the Peloponnesian War, which shortly preceded the Persian adventure of the tough, battle-hardened Greek hoplites.
