Agamemnon and Menelaus cannot sleep; they summon the Greek leaders again. It decided Odysseus and Diomed would go on a late night recon mission, meanwhile Hector is asking the Trojans for a volunteer to do the same thing. A man named Dolon volunteers; he is a good runner, and the only son among five daughters. Odysseus and Diomed capture Dolon and gather information from him. Dolon begs to be taken back to ships and ransomed; Odysseus and Diomed will have none of that, they kill Dolon on the spot. They advance closer to the Trojan camp, come across group Thracian soldiers, kill the soldiers, and steal their fine horses. Then make a mad dash to the Greek camp, and make it there.
