With Cyrus dead the motivation for his large force of rebel Persians disappeared and they fled the field. The victorious Greeks were unaware of this and began marching back towards the battle to attack the remaining Persians. Despite likely outnumbering the Greeks nearly 3 to 1 the Persians fled when the Greeks charged. Seeing as the enemy fled again the confused Greeks returned to Cyrus’s camp only to find it utterly ransacked with most of their food and supplies taken.
At the camp the Greeks realized that Cyrus had been killed and they had been abandoned so far in enemy territory that they were only a few days march from the Persian capital. The dynamics of their retreat from Persian territory were quite complex as Artaxerxes had little interest in actually capturing the Greeks. He had actually been wounded at the battle and just managed to win a civil war, however brief it may have been. For this reason Artaxerxes made no real attempt to attack the Greeks.
Despite Artaxerxes indifference, the Greeks were still not welcome in Persia, they needed food and shelter as they attempted to make their way to the coast of the Black Sea. Another Persian Satrap, Tissaphernes, allowed the Greeks to move through his territory and gave them food and shelter. One evening Tissaphernes invited the five generals and their twenty captains to a feast. The generals and officers were captured and executed, leaving the ten thousand again stranded, but now with all of their leadership gone.
Tissaphernes wagered that without their leaders the Greeks would scatter as would most certainly be the case for Persian led troops. The hope was that he could kill or capture most of the men and the rest would dwindle away. He could not have been more mistaken; The Greeks were shocked by the betrayal of Tissaphernes and the death of their leaders, but they immediately elected new leaders from among the general ranks, Xenophon being among them.
As they were in even more hostile territory the Greeks formed a hollow square marching formation and placed their baggage train and camp followers in the middle and proceeded to march day after day towards northern turkey and the coast of the Black Sea. Though the Persians had excellent skirmishers tasked with dealing damage and slowing down the square, they had little success. This is due to the heavy armor of the hoplites but also because the Greeks did their best to get their own skirmishers in position to counterattack when able.
Day after day of day of skirmishing ensued as the Greeks marched until they finally got out of Persian territory, as they crested the mountains of Turkey a shout made its way through the formation: “Thalatta! Thalatta!” meaning The Sea! The Sea!
The entire journey from recruitment to the sea took two years and by the end the “Ten Thousand” had more like 6,000 men left, though they did sell their service in Thrace before they even got all the way back to Greece. The intimidation ability of the Greek hoplites and their ability to handle themselves in Persian territory would foreshadow the success of the greatest general of the ancient world, Alexander the Great.
