The Persians hoped to throw the Greeks into confusion by this treacherous blow, and so vanquish them without much trouble; but they were not a little amazed when (in striking contrast to the spirit and organisation of their own army) a new body of generals and new subordinate officers sprang immediately and, as it were, spontaneously into being from the ranks of the Greek privates and subalterns. For in the Greek army fresh appointments to all posts were made every year; there was no regular promotion and no officer held permanent rank; on the contrary, the man who one year occupied the position of an officer frequently served as a private soldier the next. By this means almost every private soldier was qualified to step into the place of an officer, and it was an easy matter to appoint fresh leaders to the large and small divisions of the army. Xenophon, who had hitherto accompanied the march, neither in the capacity of private nor officer, but merely as a friend and comrade of one of the generals, was the first after the treacherous act of Tissaphernes to urge his countrymen not to yield to the Persian demand for submission, but to fight their way sword in hand through the enemy’s country. Only one of the colonels and captains who gathered about him demurred to his proposal. This aroused the suspicions of the rest, and, marking him more narrowly, they perceived by his pierced ears that he was by birth no Greek but a Persian. He was promptly expelled, and Xenophon and four others were appointed to succeed the generals captured by the Persians.
