Achilles did not fight in the Trojan war until the death of
Patroclus.
Achilles withdraws from battle because Agamemnon offends him by taking his concubine. Achilles states that if Briseis is not returned to him he will not fight.
Achilles saw Briseis as his; be it as slave or wife/bride, and when Agamemnon was premitted to take what was Achilles's it said that the others valued him less and so he refused to fight in the war.
In life Achilles never married, but had relations with several women: Deidamia, Briseis, Diomede; after death he is said to have lived on the White Isle and married Helen or Iphigenia; or else Medea in the Islands of the Blest.
Agamemnon threatens to take Achilles' concubine, Briseis, as punishment for losing his own prize, Chryseis. He asserts that he will seize Briseis in front of Achilles, thereby humiliating him and demonstrating his authority as the commander. This act is meant to assert Agamemnon's dominance over Achilles and is a pivotal moment that escalates their conflict in "The Iliad."
He was in a hissy fit because his commander King Agamemnon had taken over his girlfriend Briseis.
After the death of Patroclus; Agamemnon gives Achilles back Briseis.
After Achilles' death, Briseis was taken by the Greeks as a prize of war. She was awarded to Odysseus, who honored her as a symbol of Achilles' legacy. Briseis mourned Achilles deeply, reflecting her love and loyalty to him. Ultimately, her fate in the aftermath of the Trojan War is less detailed in the myths, leaving her later life somewhat ambiguous.
Briseis
Achilles loved the Trojan woman Briseis.
Briseis drives the plot of the Illiad; his telling of his weakness to Polyxena is how he dies.
Prior to being a captive of Achilles, Briseis was wife of Mynes and daughter of Briseus.
Briseis was among those to lament and mourn over the death of Patroclus. She remained with Achilles until his death, which plunged her into great grief. She soon took it upon herself to prepare Achilles for the afterlife.According to some, following his death, Briseis: "... was given to one of Achilles' comrades-at-arms just as his armor had been", after the fall of Troy.
Briseis was a princess and queen captured as a war prize of Achilles, she was mortal and had no powers.
Agamemnon
Briseis
In the context of the Iliad, Achilles' relationship with Briseis is more about possession and honor rather than love. Achilles values Briseis as a symbolic representation of his status and authority, which is why he reacts so strongly when she is taken from him by Agamemnon. Their relationship is complex and reflects the power dynamics of that society.
