We may extricate ourselves from these difficulties, by supposing that the Persian emperor only half revenged himself; that he contented himself with punishing the principal mercenary chiefs who sold the Greek troops to Cyrus; that having made a treaty with the fugitive troops, he would not descend to the meanness of violating it; that being sure that a third of these wandering Greeks would perish on the road, he abandoned them to their fate. I see no other manner of enlightening the mind of the reader on the obscurities of this march. We are astonished at the retreat of the ten thousand; but we should be much more so, if Artaxerxes, a conqueror, at the head of a hundred thousand men--at least it is said so--had allowed ten thousand fugitives to travel in the north of his vast states, whom he could crush in every village, every bridge, every defile, or whom he could have made perish with hunger and misery. However, they were furnished, as we have seen, with twenty-seven great boats, to enable them to pass the Tigris, as if they were conducted to the Indies. Thence they were escorted towards the North for several days, into the desert in which Bagdad is now situated. They further passed the river Zabata, and it was there that the emperor sent his orders to punish the chiefs. It is clear that they could have exterminated the army as easily as they inflicted punishment on the generals. It is therefore very likely that they did not choose to do so. We should, therefore, rather regard the Greek wanderers in these savage countries as wayward travellers, whom the bounty of the emperor allowed to finish their journey as they could. We may make another observation, which appears not very honorable to the Persian government. It was impossible for the Greeks not to have continual quarrels for food with the people whom they met. Pillages, desolations, and murders, were the inevitable consequence of these disorders; and that is so true, that in a road of six hundred leagues, during which the Greeks always marched irregularly, being neither escorted nor pursued by any great body of Persian troops, they lost four thousand men, either killed by peasants or by sickness. How did it happen, therefore, that Artaxerxes did not cause them to be escorted from their passage of the river Zabata, as he had done from the field of battle to the river? How could so wise and good a sovereign commit so great a fault? Perhaps he did command the escort; perhaps Xenophon, who exaggerates a little elsewhere, passes it over in silence, not to diminish the wonder of the "retreat of the ten thousand"; perhaps the escort was always obliged to march at a great distance from the Greek troop, on account of the difficulty of procuring provisions. However it might be, it appears certain that Artaxerxes used extreme indulgence, and that the Greeks owed their lives to him, since they were not exterminated.
