A Feast for Crows
While Brienne of Tarth waited for Dick Crabb, she reflected on the events beneath the walls of Highgarden when a group of knights made a wager on the taking of her maidenhead. Ser Edmund was among those knights. To woo her he had brought her flowers and offered to ride with her.  After the bet was discovered and ended, Brienne sought out and defeated Ser Edmund during the melee at Bitterbridge.
