One Trojan did not drink or sleep; this was Deiphobus, at whose house Helen was now living. He bade her come with them, for he knew that she was able to speak in the very voice of all men and women whom she had ever seen, and he armed a few of his friends and went with them to the citadel. Then he stood beside the horse, holding Helen's hand, and whispered to her that she must call each of the chiefs in the voice of his wife. She was obliged to obey, and she called Menelaus in her own voice, and Diomede in the voice of his wife, and Ulysses in the very voice of Penelope. Then Menelaus and Diomede were eager to answer, but Ulysses grasped their hands and whispered the word "Echo!" Then they remembered that this was a name of Helen, because she could speak in all voices, and they were silent; but Anticlus was still eager to answer, till Ulysses held his strong hand over his mouth. There was only silence, and Deiphobus led Helen back to his house. When they had gone away Epeius opened the side of the horse, and all the chiefs let themselves down softly to the ground. Some rushed to the gate, to open it, and they killed the sleeping sentinels and let in the Greeks. Others sped with torches to burn the houses of the Trojan princes, and terrible was the slaughter of men, unarmed and half awake, and loud were the cries of the women. But Ulysses had slipped away at the first, none knew where. Neoptolemus ran to the palace of Priam, who was sitting at the altar in his courtyard, praying vainly to the Gods, for Neoptolemus slew the old man cruelly, and his white hair was dabbled in his blood. All through the city was fighting and slaying; but Menelaus went to the house of Deiphobus, knowing that Helen was there. In the doorway he found Deiphobus lying dead in all his armour, a spear standing in his breast. There were footprints marked in blood, leading through the portico and into the hall. There Menelaus went, and found Ulysses leaning, wounded, against one of the central pillars of the great chamber, the firelight shining on his armour. "Why hast thou slain Deiphobus and robbed me of my revenge?" said Menelaus. "You swore to give me a gift," said Ulysses, "and will you keep your oath?" "Ask what you will," said Menelaus; "it is yours and my oath cannot be broken." "I ask the life of Helen of the fair hands," said Ulysses "this is my own life-price that I pay back to her, for she saved my life when I took the Luck of Troy, and I swore that hers should be saved."
