The most fascinating part is the religiosity of Xenophon and his men. A dead religion ruled every moment, every action of every day for these men. No decision performed and no mission embarked was upon without consulting the entrails or awaiting divine signage. Better than Dawkins or Hitchens as an indictment of religion.

Aside from that, the first person (though years later) account is a fascinating look at the day-to-days and politics of the period.
