  ====''A Clash of Kings''====
  Brienne joins Renly Baratheon's army when he marches on King's Landing. She wins the Melee at Bitterbridge, held by Renly, and is permitted to join Renly's Rainbow Guard as her prize. When it becomes apparent that Renly will be forced to battle his brother Stannis, Brienne is assigned as his standard bearer. However, before the battle, in which Renly intends his brother's death, Renly is assassinated by a shadow. Brienne is accused of the murder before Catelyn Stark is able to convince those present of her innocence, and Brienne accompanies Catelyn back to Riverrun. Although Brienne wishes to have revenge on Stannis for Renly's death, Catelyn persuades Brienne to serve her instead. Catelyn later goes to visit the captive Jaime Lannister in the dungeons; when Jaime begins to mock Catelyn's husband Ned's infidelity, Catelyn calls for Brienne's sword.
