Notwithstanding these two great mistakes,—one on the present occasion, one previously, at the battle of Kunaxa, in keeping the Greeks on the right contrary to the order of Cyrus,—both committed by Klearchus, the loss of that officer was doubtless a great misfortune to the army; while, on the contrary, the removal of Menon was a signal benefit,—perhaps a condition of ultimate safety. A man so treacherous and unprincipled as Xenophon depicts Menon, would probably have ended by really committing towards the army that treason, for which he falsely took credit at the Persian court in reference to the seizure of the generals. The impression entertained by Klearchus, respecting the hopeless position of the Greeks in the heart of the Persian territory after the death of Cyrus, was perfectly natural in a military man who could appreciate all the means of attack and obstruction which the enemy had it in their power to employ. Nothing is so unaccountable in this expedition as the manner in which such means were thrown away,—the spectacle of Persian impotence. First, the whole line of upward march, including the passage of the Euphrates, left undefended; next, the long trench dug across the frontier of Babylonia, with only a passage of twenty feet wide left near the Euphrates, abandoned without a guard; lastly, the line of the Wall of Media and the canals which offered such favorable positions for keeping the Greeks out of the cultivated territory of Babylonia, neglected in like manner, and a convention concluded, whereby the Persians engaged to escort the invaders safe to the Ionian coast, beginning by conducting them through the heart of Babylonia, amidst canals affording inexpugnable defences if the Greeks had chosen to take up a position among them. The plan of Tissaphernes, as far as we can understand it, seems to have been, to draw the Greeks to some considerable distance from the heart of the Persian empire, and then to open his schemes of treasonable hostility, which the imprudence of Klearchus enabled him to do, on the banks of the Great Zab, with chances of success such as he could hardly have contemplated. We have here a fresh example of the wonderful impotence of the Persians. We should have expected that, after having committed so flagrant an act of perfidy, Tissaphernes would at least have tried to turn it to account; that he would have poured, with all his forces and all his vigor, on the Grecian camp, at the moment when it was unprepared, disorganized, and without commanders. Instead of which, when the generals (with those who accompanied them to the Persian camp) had been seized or slain, no attack whatever was made except by small detachments of Persian cavalry upon individual Greek stragglers in the plain. One of the companions of the generals, an Arcadian named Nikarchus, ran wounded into the Grecian camp, where the soldiers were looking from afar at the horsemen scouring the plain without knowing what they
