Even though his father opened the gates, Hector refuses to retreat. When Achilles attacks him, Hector runs from him. Upon Zeus' consent, Athena disguises herself as Deïphobos and persuades him to stop running, but disappears when Hector turns to her to fight against Achilles. Hector pleads to respect the loser's body, which Achilles denies and attacks anyways. Achilles kills him and drags him away by his chariot. The city of Troy falls into despair, especially Hector's wife, Andromache. After an appearance from Patroklos' ghost, Achilles gives him a proper burial, and the funeral games commence, even though Achilles does not participate in them. Achilles, still distraught of his friend's death, beats the body of Hector. With the help of the gods, Priam is able to infiltrate the Greek camp to ask for his son's body. Both Achilles and Priam eat and when Priam returns with the body, the Trojans mourn for nine days, burn his body on the tenth and bury his body on the eleventh day.

Now the Trojans have the rest of the war to worry about. There will be nothing of the walls I built left when the Greeks are done. And Achilles seemed to let go of his close friend, if only for a bit and was able to mourn with Priam.
