"Come, then, let us be going," said Ulysses, "for the night is late, and the dawn is near." As these two chiefs had no armour on, they borrowed shields and leather caps from the young men of the guard, for leather would not shine as bronze helmets shine in the firelight. The cap lent to Ulysses was strengthened outside with rows of boars' tusks. Many of these tusks, shaped for this purpose, have been found, with swords and armour, in a tomb in Mycenae, the town of Agamemnon. This cap which was lent to Ulysses had once been stolen by his grandfather, Autolycus, who was a Master Thief, and he gave it as a present to a friend, and so, through several hands, it had come to young Meriones of Crete, one of the five hundred guards, who now lent it to Ulysses. So the two princes set forth in the dark, so dark it was that though they heard a heron cry, they could not see it as it flew away. While Ulysses and Diomede stole through the night silently, like two wolves among the bodies of dead men, the Trojan leaders met and considered what they ought to do. They did not know whether the Greeks had set sentinels and outposts, as usual, to give warning if the enemy were approaching; or whether they were too weary to keep a good watch; or whether perhaps they were getting ready their ships to sail homewards in the dawn. So Hector offered a reward to any man who would creep through the night and spy on the Greeks; he said he would give the spy the two best horses in the Greek camp. Now among the Trojans there was a young man named Dolon, the son of a rich father, and he was the only boy in a family of five sisters. He was ugly, but a very swift runner, and he cared for horses more than for anything else in the world. Dolon arose and said, "If you will swear to give me the horses and chariot of Achilles, son of Peleus, I will steal to the hut of Agamemnon and listen and find out whether the Greeks mean to fight or flee." Hector swore to give these horses, which were the best in the world, to Dolon, so he took his bow and threw a grey wolf's hide over his shoulders, and ran towards the ships of the Greeks. Now Ulysses saw Dolon as he came, and said to Diomede, "Let us suffer him to pass us, and then do you keep driving him with your spear towards the ships, and away from Troy." So Ulysses and Diomede lay down among the dead men who had fallen in the battle, and Dolon ran on past them towards the Greeks. Then they rose and chased him as two greyhounds course a hare, and, when Dolon was near the sentinels, Diomede cried "Stand, or I will slay you with my spear!" and he threw his spear just over Dolon's shoulder. So Dolon stood still, green with fear, and with his teeth chattering. When the two came up, he cried, and said that his father was a rich man, who would pay much gold, and bronze, and iron for his ransom.
