While skimming The Book of Brothers, King Joffrey Baratheon reads through the entry on Ser Arthur Dayne, mentioning his leading of the attack on the Kingswood Brotherhood and his defeat of the Smiling Knight, one of its members, in single combat. The Book of Brothers also mentions that at one point he was granted temporary command over the Kingsguard after Lord Commander Gerold Hightower suffered injuries. The entry concludes by recounting how he perished at the end of Robert's Rebellion alongside Ser Gerold at the Red Mountains of Dorne, fighting Lord Eddard Stark.
