Hugh Hammer Ulf White abandon post Season 3 in House of the Dragon Season 3 Episode 2 — and Daemon’s reaction when he returns to Dragonstone to find them gone tells you exactly how dangerous that is.
He does not panic. He does not scramble. He slaps Ulf and moves on. But the controlled response from the most experienced commander in the Black faction cannot disguise what the show is setting up: two men with two of the most powerful dragons alive are now operating outside anyone’s authority, and the war has just changed hands.
What Happens in Episode 2
When Daemon is recalled to Dragonstone following Jace’s death, he returns to find that Hugh Hammer and Ulf White have left their assigned watch post. The two dragonseed riders — Hugh on Vermithor, Ulf on Silverwing — were positioned as a defensive screen while Daemon was in the Riverlands. They left.
When they attempt to explain their reasons to Daemon, the conversation does not go well. Ulf receives a slap. Neither man is forgiven. Neither man is punished beyond that.
This matters. Daemon’s response — irritated, contemptuous, but not escalating — reflects the core problem with the dragonseed riders from the very beginning: they bonded with dragons through Rhaenyra’s desperate open call, not through institutional loyalty or personal obligation. Daemon cannot execute them. He cannot chain them. He can slap Ulf White and hope that is enough.
It is not going to be enough.
Daemon has two dragonriders he cannot fully trust, riding two of the most powerful dragons in the war. He knows it. He is managing it. He will not be able to manage it indefinitely.

Who Are Hugh Hammer and Ulf White?
Hugh Hammer and Ulf White are dragonseeds — commoners with distant Valyrian blood who successfully claimed unmounted dragons during Rhaenyra’s Red Sowing in Season 2. Hugh claimed Vermithor, the massive bronze dragon once ridden by King Jaehaerys I — the largest living dragon after Vhagar. Ulf claimed Silverwing, once ridden by Queen Alysanne.
Both men come from nothing. Both suddenly command something extraordinary. And neither of them was prepared — psychologically, politically, or personally — for what it means to ride a dragon in a war being fought by people who will never treat them as equals.
Hugh Hammer is played by Kieran Bew. Ulf White is played by Tom Bennett. Both are new to Season 3 but established with enough screen time to make their eventual betrayal land with full weight when it arrives.
The abandonment of their post in Episode 2 is not the betrayal itself. It is the show establishing that these are men who do what they want when the authority watching them turns away. That is the foundation on which everything that follows is built.
Why Abandoning Post Matters More Than It Appears
Hugh Hammer Ulf White abandon post Season 3 moment in Episode 2 is easy to read as a minor disciplinary incident. It is not. It is the show’s first confirmation that the dragonseed problem Rhaenyra always carried is now active rather than theoretical.
Rhaenyra’s Red Sowing gave dragons to people who wanted them — not to people who were loyal to her cause, not to people who understood the war’s stakes, not to people who had earned the trust that comes with commanding a weapon of mass destruction. She needed riders. She got riders. What she did not get was certainty about what those riders would do when someone offered them a better deal.
Hugh and Ulf leaving their post is not a significant military event. It is a behavioural signal: these are men who weigh their own interests above their assigned duties. That assessment will be confirmed at Second Tumbleton, when those interests align with the Green faction’s offer of lands and titles — and two Black dragons turn on Black soldiers above a burning town.
Rhaenyra is on the Iron Throne. Her faction has taken the capital. And two of her most powerful dragon assets are being ridden by men who just demonstrated they leave when they feel like it.
Where Hugh and Ulf Are Going
The Hugh Hammer and Ulf White abandon post episode does not specify where they go after leaving. That absence is deliberate. The show is not yet ready to show its hand on the timeline between their departure and the Second Battle of Tumbleton.
What can be established is the direction of travel. The Hightower army under Ormund Hightower — now learning that King’s Landing has fallen — is somewhere south of the capital. Tumbleton is a town south of King’s Landing in the Reach. The approaching collision between the Green faction’s southern army and whatever forces the Blacks can muster to stop them is where Hugh and Ulf eventually end up.
How they get there — whether they are approached by Green faction agents, whether they approach of their own accord, whether the show depicts the negotiation or leaves it off-screen as the source material does — is one of Season 3’s most carefully protected plot threads.
What is already clear from Episode 2 is that Daemon knows they are untrustworthy, cannot do much about it, and is about to have larger problems than two absent riders. Because King’s Landing is taken, Aemond is at Harrenhal, and Aegon is heading toward Criston Cole. The Green faction’s military option is not exhausted. And Hugh and Ulf are somewhere in the field with two dragons, no loyalty, and a war that has just become much more interesting to either side.
What This Means for Rhaenyra’s Reign
Hugh Hammer and Ulf White abandon post at the precise moment Rhaenyra is trying to consolidate a new reign in a city that does not fully trust her. Their absence is one more thing she cannot control — one more loose thread in a tapestry that is already pulling apart at several corners simultaneously.
Daemon is managing it. For now. But Daemon is also the person who recruited the dragonseeds, who ran the watch, and who is now back at Dragonstone rather than in the Riverlands where his army needs him. The dragonseed problem is going to land on Rhaenyra eventually. Episode 2 is the moment the show confirms it is a problem.
Six episodes remain. Hugh and Ulf are somewhere out there with Vermithor and Silverwing. Tumbleton is waiting.
