They then deliberated together, and Xenophon asking what hindered them from taking the place, Chirisophus replied: "The only approach to it is the one which you see; but when any of our men attempt to pass along it, the enemy roll down stones over yonder impending rock, and whoever is struck is treated as you behold;" and he pointed, at the same moment, to some of the men who had had their legs and ribs broken. "But if they expend all their stones," rejoined Xenophon, "is there anything else to prevent us from advancing? For we see, in front of us, only a few men, and but two or three of them armed. The space, too, through which we have to pass under exposure to the stones is, as you see, only about a hundred and fifty feet in length; and of this about a hundred feet is covered with large pine trees in groups, against which, if the men place themselves, what would they suffer either from the flying stones or the rolling ones? The remaining part of the space is not above fifty feet, over which, when the stones cease, we must pass at a running pace." "But," said Chirisophus, "the instant we offer to go to the part covered with trees, the stones fly in great numbers." "That," cried Xenophon, "would be the very thing we want, for thus they will exhaust their stones the sooner. Let us then advance, if we can, to the point whence we shall have but a short way to run, and from which we may, if we please, easily retreat." Chirisophus and Xenophon, with Callimachus of Parrhasia, one of the captains, who had that day the lead of all the other captains of the rear-guard, then went forward, all the rest of the captains remaining out of danger. Next, about seventy of the men advanced under the trees, not in a body, but one by one, each sheltering himself as he could. Agasias of Stymphalus, and Aristonymus of Methydria, who were also captains of the rear-guard, with some others were at the same time standing behind, without the trees, for it was not safe for more than one company to stand under them. Callimachus then adopted the following stratagem: he ran forward two or three paces from the tree under which he was sheltered, and when the stones began to be hurled, hastily drew back; and at each of his sallies more than ten cartloads of stones were spent.
