“Thank Heaven,” (said Xenophon in the evening, when Cheirisophus reproached him for imprudence in quitting the main body to charge cavalry, whom yet he could not reach.) “Thank Heaven, that our enemies attacked us with a small detachment only, and not with their great numbers. They have given us a valuable lesson, without doing us any serious harm.” Profiting by the lesson, the Greek leaders organized during the night and during the halt of the next day, a small body of fifty cavalry; with two hundred Rhodian slingers, whose slings, furnished with leaden bullets, both carried farther and struck harder than those of the Persians hurling large stones. On the ensuing morning, they started before daybreak, since there lay in their way a ravine difficult to pass. They found the ravine undefended (according to the usual stupidity of Persian proceedings), but when they had got nearly a mile beyond it, Mithridates reappeared in pursuit with a body of four thousand horsemen and darters. Confident from his achievement of the preceding day, he had promised, with a body of that force, to deliver the Greeks into the hands of the satrap. But the latter were now better prepared. As soon as he began to attack them, the trumpet sounded,—and forthwith the horsemen, slingers, and darters, issued forth to charge the Persians, sustained by the hoplites in the rear. So effective was the charge, that the Persians fled in dismay, notwithstanding their superiority in number; while the ravine so impeded their flight that many of them were slain, and eighteen prisoners made. The Greek soldiers of their own accord mutilated the dead bodies, in order to strike terror into the enemy.[155] At the end of the day’s march they reached the Tigris, near the deserted city of Larissa, the vast, massive, and lofty brick walls of which (twenty-five feet in thickness, one hundred feet high, seven miles in circumference) attested its former grandeur. Near this place was a stone pyramid, one hundred feet in breadth, and two hundred feet high; the summit of which was crowded with fugitives out of the neighboring villages. Another day’s march up the course of the Tigris brought the army to a second deserted city called Mespila, nearly opposite to the modern city of Mosul. Although these two cities, which seem to have formed the continuation or the substitute of the once colossal Nineveh or Ninus, were completely deserted,—yet the country around them was so well furnished with villages and population, that the Greeks not only obtained provisions, but also strings for the making of new bows, and lead for bullets to be used for the slingers.[156] [155] Xen.
