The mercenaries, known as the Ten Thousand, found themselves without leadership far from the sea, deep in hostile territory near the heart of Mesopotamia, with a hostile population and armies to deal with.
They elected new leaders, including Xenophon himself.

Dodge says of Xenophon's generalship, "Xenophon is the father of the system of retreat, the originator of all that appertains to the science of rear-guard fighting.
He reduced its management to a perfect method.
More originality in tactics has come from the Anabasis than from any dozen other books.
Every system of war looks to this as to the fountain-head when it comes to rearward movements, as it looks to Alexander for a pattern of resistless and intelligent advance.
Necessity to Xenophon was truly the mother of invention, but the centuries since have devised nothing to surpass the genius of this warrior.
No general ever possessed a grander moral ascendant over his men.
None ever worked for the safety of his soldiers with greater ardor or to better effect."
 
Xenophon and his men initially had to deal with volleys by a minor force of harassing Persian missile cavalry.
Every day, these cavalry, finding no opposition from the Ten Thousand, moved cautiously closer and closer.
One night, Xenophon formed a body of archers and light cavalry.
When the Persian cavalry arrived the next day, now firing within several yards, Xenophon suddenly unleashed his new cavalry in a shock charge, smashing into the stunned and confused enemy, killing many and routing the rest.
 Tissaphernes pursued Xenophon with a vast force, and when the Greeks reached the wide and deep Great Zab River, it seemed they were surrounded.
However, Xenophon quickly devised a plan: all goats, cows, sheep and donkeys were slaughtered and their bodies stuffed with hay, laid across the river and sewn up and covered with dirt so as not to be slippery.
This created a bridge across which Xenophon led his men before the Persians could get to them.
That Xenophon was able to acquire the means of feeding his force in the heart of a vast empire with a hostile population was astonishing.
Dodge notes, "On this retreat also was first shown the necessary, if cruel, means of arresting a pursuing enemy by the systematic devastation of the country traversed and the destruction of its villages to deprive him of food and shelter.
And Xenophon is moreover the first who established in rear of the phalanx a reserve from which he could at will feed weak parts of his line.
This was a superb first conception."

The Ten Thousand eventually made their way into the land of the Carduchians, a wild tribe inhabiting the mountains of modern southeastern Turkey.
The Carduchians were "a fierce, war-loving race, who had never been conquered.
Once the Great King had sent into their country an army of 120,000 men, to subdue them, but of all that great host not one had ever seen his home again."
The Ten Thousand made their way in and were fired at by stones and arrows for several days before they reached a defile where the main Carduchian host sat.
In  the Battle of the Carduchian Defile, Xenophon had 8,000 men feint at this host and marched the other 2,000 to a pass revealed by a prisoner under the cover of a rainstorm, and "having made their way to the rear of the main pass, at daylight, under cover of the morning mist, they boldly pushed in upon the astonished Carducians.
The blare of their many trumpets gave notice of their successful detour to Xenophon, as well as added to the confusion of the enemy.
The main army at once joined in the attack from the valley side, and the Carducians were driven from their stronghold."
After heavy mountain fighting in which Xenophon showed the calm and patience needed for the situation, the Greeks made their way to the northern foothills of the mountains at the Centrites River, only to find a major Persian force blocking the route north.
With the Carduchians surging toward the Greek rear, Xenophon again faced the threat of total destruction in battle.
