The Battle of Tumbleton in House of the Dragon Season 3 maintains the core story from George R.R. Martin’s Fire and Blood while making several significant changes. The HBO adaptation captures the essential narrative of a major defeat for Rhaenyra’s forces, complete with betrayals from her dragonriders, but alters numerous details in the process.
One of the most dramatic reversals involves who controls the town at the battle’s start. In the source material, Rhaenyra’s forces occupy Tumbleton and face Ormund’s attacking armies. The show inverts this dynamic, establishing Ormund’s presence first and forcing Rhaenyra to decide whether to attack her own subjects or appear weak. This change serves multiple narrative purposes, exploring both Rhaenyra’s moral conflict and Ormund’s increasingly brutal tactics, including his use of children as human shields—a detail exclusive to the adaptation.
The television version introduces entirely new storylines absent from the books. Gwayne Hightower and Daeron Targaryen attempt to use the captured Corlys Velaryon to negotiate peace, a subplot that doesn’t exist in Fire and Blood, where neither character participates in the battle. Additionally, Daemon Targaryen fights at Tumbleton in the show despite being nowhere near the conflict in Martin’s text. The search for the drunk dragonrider Ulf the White and Hugh Hammer’s personal journey to find his estranged wife represent additional show-only content that reimagines character motivations and arcs not present in the source material.
