In Book 10, Diomedes and Odysseus capture and interrogate Dolon, a Trojan spy. Dolon, in an effort to save his life, tells them the positions of the Trojans and all of their allies. He reveals to them the location of a group of Thracians who have just arrived to help the Trojans. Diomedes then kills Dolon and strips him of his armor. The two Achaean spies proceed to the Thracian camp, where they kill soldiers in their sleep and steal their horses. Is this heroic? What other options did they have? Should there be rules in a war? Why or why not? Explain your response logically, considering both sides.
