354 BC deaths

Xenophon of Athens (; ; 355/354 BC) was a Greek military leader, philosopher, and historian. At the age of 30, he was elected as one of the leaders of the retreating Greek mercenaries, the Ten Thousand, who had been part of Cyrus the Younger's attempt to seize control of the Achaemenid Empire. As the military historian Theodore Ayrault Dodge wrote, "the centuries since have devised nothing to surpass the genius of this warrior".
