Penthesilea arrives in Troy the night before the fighting is due to recommence following Hector's death and funeral. She came to Troy to prove to others that her people, the Amazons, are great warriors and can share the hardships of war and to appease the Gods for accidentally killing her sister Hippolyta while hunting. She arrived with twelve companions and promised the Trojans that she would kill Achilles. On her first and only day of fighting, Penthesilea kills many men and clashes with Telamonian Ajax, although there is no clear victor, before she comes face to face with Achilles, who had been summoned by Telamonian Ajax. Prior to Achilles' entrance, Penthesilea had tried to fight Telamonian Ajax but he had merely laughed off her attempts, thinking her an unfit opponent. With only one blow to her breastplate, Achilles knocks her to the ground and she begs for her life. He is unmoved, kills her, and mocks her corpse until he removes her helmet and feels strong remorse.
