Lord of Horn Hill
During Robert's Rebellion, Lord Randyll Tarly commanded the vanguard of the Reach at the Battle of Ashford, where he killed Lord Cafferen and forced Lord Robert Baratheon to retreat. Randyll's liege, Lord Mace Tyrell, took credit for the victory, however.
A Clash of Kings
Lord Randyll is among the lords that join their forces to Renly Baratheon's beneath Bitterbridge. After Renly's death at Storm's End, Lord Randyll rides back to Bitterbridge where he captures Renly's stores and puts many men to death, mainly Florent men-at-arms, lest they go over to Stannis along with their lords. Randyll joins his liege lord, Lord Mace Tyrell, and the Tyrell-Lannister alliance at the Battle of the Blackwater, where he commands the center of the host.
A Storm of Swords
A Feast for Crows
The timid and cowardly Lord of Maidenpool, William Mooton, does not dare confront Lord Randyll, who rules the town in all but name. Lord Randyll arranges a betrothal for his son and heir, Dickon Tarly, to William's eldest daughter and heir, Eleanor Mooton.
A Dance with Dragons
Randyll returns to King's Landing upon receiving news of the arrest of Margaery Tyrell. He receives custody of her and her cousins after swearing a holy oath to return them for trial. As part of Lord Regent Kevan Lannister's efforts to assuage the men of the Reach, Lord Tarly is named justiciar on the small council of King Tommen I Baratheon.
