The Exploits of Xenophon by Geoffrey Household

Thousands of miles from home, one soldier leads an army to safety
The war with Sparta is over, and Athens is at peace for the first time in thirty years. Their Greek enemies subdued, the generals of Athens turn their eyes to the East, where the Empire stretches to the edge of the known world. Never before have Greek soldiers marched into Persia. Xenophon will be among the first. A warrior whose bravery is matched only by his intelligence, Xenophon is a natural leader. When his army of ten thousand men is stranded far from home, it is up to him to lead them back to Greece without sacrificing the principles of demacy that they hold so dear.

A retelling of Xenophon's classic Anabasis, this is a thrilling tale of bravery and survival, in which the mind is as valuable a weapon as the sword.
