Answer :
After Hector kills Patroclus, Achilles is blind with rage. He leaves many Trojans in his wake as he travels to find Hector to get revenge. He succeeds in killing Hector and parades him around the walls of Troy.
After the battle between Achilles and Hector concludes—a battle that sees the defeat of Hector by Achilles—Achilles ties the body of Hector to his chariot and drags it around the city walls as a sign of victory, hate, and disrespect.
