Having learned all that he needs to know, Diomede ruthlessly slays Dolon. Odysseus thanks Athene, and hides the poor spoils of the dead, marking the place. They then creep into the dark camp of the sleeping Thracians, and as Diomede slays them Odysseus drags each body aside, to leave a clear path for the horses, that they may not plunge and tremble when they are led forth, "for they were not yet used to dead men." No line in Homer shows more intimate knowledge and realisation of horses and of war. Odysseus drives the horses of Rhesus out of the camp with the bow of Meriones; he has forgotten to take the whip from the chariot. Diomede, having slain King Rhesus asleep, thinks whether he shall lift out the chariot (war chariots were very light) or drag it by the pole; but Athene warns him to be going. He "springs upon the steeds," and they make for their camp. It is not clearly indicated whether they ride or drive (X., 5 I 3, 527-528, 541); but, suppose that they ride, are we to conclude that the fact proves "lateness"? The heroes always drive in Homer, but it is inconceivable that they could not ride in cases of necessity, as here, if Diomede has thought it wiser not to bring out the chariot and harness the horses. Riding is mentioned in _Iliad_, XV. 679, in a simile; again, in a simile, _Odyssey_, V. 37 I. It is not the custom for heroes to ride; the chariot is used in war and in travelling, but, when there are horses and no chariot, men could not be so imbecile as not to mount the horses, nor could the poet be so pedantic as not to make them do so. The shields would cause no difficulty; they would be slung sideways, like the shields of knights in the early Middle Ages. The pair, picking up Dolon's spoils as they pass, hurry back to the chiefs, where Nestor welcomes them. The others laugh and are encouraged (to encourage them and his audience is the aim of the poet); while the pair go to Diomede's quarters, wash off the blood and sweat from their limbs in the sea, and then "enter the polished baths," common in the _Odyssey_, unnamed in the Iliad. But on no other occasion in the Iliad are we admitted to view this part of heroic toilette. Nowhere else, in fact, do we accompany a hero to his quarters and his tub after the day's work is over. Achilles, however, refuses to wash, after fighting, in his grief for Patroclus, though plenty of water was being heated for the purpose, and it is to be presumed that a bath was ready for the water (_Iliad_, XXIII. 40). See, too, for Hector's bath, XXII. 444.
