Book 7
3.37
And Xenophon said: Well, now, consider this point, whether, if we are to make a night march, the Greek practice is not the better: in our marches by day, you know, that part of the army takes the lead which is suited to the nature of the ground in each case, whether it be hoplites or peltasts or cavalry; but by night it is the practice of the Greeks that the slowest arm should lead the way;
3.38
for thus the various parts of the army are least likely to become separated, and men are least likely to drop away from one another without knowing it; and it often happens that scattered divisions fall in with one another and in their ignorance inflict and suffer harm.
3.39
Then Seuthes replied: You are right, and I will adopt your practice. I will give you guidesWhich are necessary now that the Greeks, whose hoplites form the slowest arm, are to lead the way. from among the oldest men, who know the country best, and I myself will bring up the rear with my horsemen; for I can speedily reach the front if need be. Then they gave out Athena as the watchword, on account of their kinship.cp. Xen. Anab. 7.2.31. After this conference they went to rest.
3.40
When it was about midnight, Seuthes was at hand with his horsemen armed with breast-plates and his peltasts equipped with their arms. And as soon as he had given over their guides to the Greeks, the hoplites took the lead, the peltasts followed, and the horsemen brought up the rear.
3.41
When day came, Seuthes rode along to the front and expressed his approval of the Greek practice. For many times, he said, while marching by night with even a small force he himself, along with his cavalry, had got separated from his infantry; but now, he continued, we find ourselves at daybreak all together, just as we should be. But do you wait where you are and take a rest, and I will return after I have looked around a little. With these words he rode off along a mountain side, following a kind of road.
