Inside the Fiery Chaos: 'House of the Dragon' Cast Reveals Westeros' Deadliest Naval Clash Secrets

The highly anticipated and devastating sequence known as the Battle of the Gullet was strategically reserved for the House of the Dragon Season 3 premiere, a decision made by showrunner Ryan Condal to "rebalance the season" and provide this pivotal event with the "time and the space that it deserves." Fans, initially expecting this bloody naval conflict in the concluding episodes of Season 2, will find their expectations met and exceeded by the premiere episode, "Salt and Sea, Fire and Blood." Clocking in at over an hour, this episode, written by Condal and directed by Loni Peristere, represents the culmination of two years of meticulous preparation, design efforts, and months of rigorous actor training, all aimed at creating a visceral and realistic portrayal of the battle.

Condal had previously revealed the extensive use of practical effects during filming, minimizing CGI outside of the critical moments involving dragons. The battle's depiction is not only a massive spectacle but also carries profound personal consequences for Rhaenyra's faction in the Targaryen civil war, featuring some of the most devastating losses to date.

The Battle of the Gullet unfolds across two distinct theaters: the tumultuous naval engagement between Corlys Velaryon's fleet and the Triarchy's ships, and the chaotic aerial combat raging in the skies above. Steve Toussaint, who portrays Corlys Velaryon, expressed immense "joyous" in finally showcasing his character's legendary prowess as the "Sea Snake." Filming involved authentic ship settings and intense sword fighting with pirates, allowing Toussaint to embody Corlys in his element. He likened the experience to "a kid on the playground" with "incredibly expensive toys," vividly recalling childhood imaginings.

Abigail Thorn, who joined the series as Admiral Sharako Lohar, the brash pirate commanding the Triarchy's fleet, echoed Toussaint's enthusiasm, describing the filming as "the most fun I've ever had," following months of intense preparation. Lohar's true motivations, however, are far more personal than her initial alliance with Tyland Lannister suggests. She reveals her intent to seek vengeance on Corlys for past devastations inflicted upon her people, aiming to sack High Tide, the seat of House Velaryon, and personally hunt down Corlys. Thorn drew inspiration from Captain Ahab of Moby-Dick and Ricardo Montalbán's Khan in Star Trek II, describing Corlys as Lohar's "white whale." Lohar is willing to sacrifice everything, including her own men and life, for a chance at revenge.

The climactic confrontation between Lohar and Corlys is brutal. Discussions between Thorn and director Loni Peristere shaped this "Captain Ahab moment," with Thorn even attempting a take where she literally spits at Steve Toussaint, embracing the intensity of "From hell's heart, I stab at thee." Though both characters inflict severe damage, Corlys's fate is left ambiguous after he falls into the sea as his ship runs aground. His right-hand sailor and secret bastard son, Alyn of Hull, played by Abubakar Salim, immediately steps in. Stripping off his armor, Alyn believes Lohar responsible for Corlys's presumed death and engages her in a visceral fight, culminating in them tumbling into waist-deep water.

Salim described the evolution of Alyn and Lohar's fight from a planned choreographed stunt to a more "brutal and just horrible" on-set reality, driven by the characters' exhaustion and singular intention to kill or be killed. Thorn found nuance in Lohar's final moments, choosing how her character reacted to each hit and the realization of impending death. Alyn ultimately triumphs by holding Lohar underwater and finishing her with a knife. Thorn confirmed Lohar's death as her most illuminating scene, revealing that beneath the formidable fighter, Lohar was "just this scared little girl," a poignant reflection on the cost of war and vengeance.

Concurrently, in the skies above, the arrival of dragons marks a tragic turn. Rhaenyra's eldest son, Jacaerys (Harry Collett), against his mother's wishes, takes her place at the Gullet, accompanied by his betrothed, Baela Targaryen (Bethany Antonia), on her dragon Moondancer. Unbeknownst to them, Baela's sister Rhaena (Phoebe Campbell) has just bonded with the wild dragon Sheepstealer in the Vale and is flying to High Tide. Campbell described filming dragon-riding scenes as "the best kept secret on-set," though Rhaena and Sheepstealer's bond, a significant departure from Fire & Blood, quickly turns catastrophic.

Sheepstealer, untamed and unpredictable, indiscriminately burns ships, causing Jace and Baela to mistake him for an enemy. As Sheepstealer targets Baela and Moondancer, Jace and Vermax intervene, only for Jace to recognize Rhaena. However, his approach makes them Sheepstealer's new target. Jace attempts to evade by flying lower, but this proves fatal for both him and Vermax. Unlike the book's depiction of Vermax being hit by a grappling hook and crashing, the show portrays Vermax slowly sinking into the sea as Jace desperately tries to keep him airborne. Collett emphasized Jace's belief in always finding a way out, making the scene "10 times more tense" for viewers hoping for his survival.

Despite unbuckling from Vermax's saddle and grabbing onto debris, any hope for Jace's survival is brutally extinguished when Triarchy pirates on a nearby ship shoot him with multiple arrows. Collett noted Jace's awareness of the battle's inherent danger, making his death a "true shock" yet expected for the character. Rhaena, witnessing the tragedy, is left to grapple with the immense "weight of responsibility" for Jace's death, acknowledging her role in causing the disaster. The episode powerfully underscores the devastating toll of war and vengeance, with Rhaenyra losing another son without even knowing it.
