⚡ Quick Answer

The Siege of Meereen was the decisive harbor battle of 305 AC in which the Wise Masters of Yunkai, Astapor, and Volantis broke a fragile truce and sent a coalition fleet to retake Meereen from Daenerys Targaryen. Daenerys returned astride Drogon in the middle of the assault, freed her two remaining dragons, and burned the Masters’ ships at anchor, while the Unsullied, the Second Sons, and a newly sworn Dothraki khalasar broke the landing force on the beach. The result was a total Targaryen victory that ended organized slaver resistance in the region.

What Was the Siege of Meereen?

The Siege of Meereen was the closing battle of Daenerys Targaryen’s long campaign across Slaver’s Bay, fought not within the city’s walls but in the waters and sand just beyond them. By 305 AC, Meereen had already endured years of unrest — Sons of the Harpy insurgents in the streets, a failed evacuation by sea, and a dragonpit uprising at Daznak’s Pit — but it was the arrival of a combined slaver fleet from Yunkai, Astapor, and Volantis that brought the conflict to its final, decisive stage.

The battle sits at the end of the broader Conquest of Slaver’s Bay, the campaign in which Daenerys Targaryen of House Targaryen dismantled the slave trade of Astapor, Yunkai, and Meereen. Tyrion Lannister, acting as her hand in the city during her absence, had negotiated a seven-day truce with the Wise Masters — a truce they shattered the moment they believed her gone for good, choosing instead to land troops and bombard the Great Pyramid with incendiary fire from offshore.

What followed mattered far beyond Meereen’s walls. A slaver victory would have unraveled every gain of the abolition campaign and stranded Daenerys without a base in Essos. Her victory instead secured the city, broke the economic and military power of the Masters for a generation, and freed the fleet and manpower she would need to sail for Westeros. The battlefield itself — the harbor mouth, the open beach south of the Great Pyramid of Meereen, and the anchorage where the slaver ships massed — remains one of the most referenced sites in any modern account of the war.

Siege of Meereen: Full Battle Breakdown

Prelude

The Truce and Its Collapse

With Daenerys missing in the Dothraki Sea and Meereen reeling from the Sons of the Harpy insurgency, Tyrion Lannister brokered a seven-day truce with the Wise Masters of Yunkai, Astapor, and Volantis, buying the city time to stabilize. The Masters used the respite instead to muster a joint fleet, gambling that the dragon queen would not return before they struck. When word reached them that she had vanished, possibly for good, they broke the truce outright and sailed for Meereen’s harbor.

Opening Moves

Bombardment of the Great Pyramid

The slaver fleet opened the battle with catapult fire directed at the Great Pyramid itself, setting sections of the city alight and forcing Tyrion, Missandei, and Grey Worm to organize an emergency defense. Unsullied spearmen formed lines along the harbor approach while the Second Sons under Daario Naharis held the flanks, buying time as the Masters began landing soldiers on the beach south of the city walls.

Turning Point

Drogon’s Return

At the height of the assault, Daenerys arrived over the harbor on Drogon, descending into the Great Pyramid’s pit to free Rhaegal and Viserion from the chains that had bound them since the Daznak’s Pit uprising. For the first time since their imprisonment, all three of her dragons took flight together — a sight that broke the morale of the landing force before a single ship had burned.

Climax

The Burning of the Fleet

Drogon, Rhaegal, and Viserion swept low over the anchorage, setting ship after ship ablaze while the Dothraki khalasar, ferried in by Daario’s forces, crashed into the slaver soldiers stranded on the beach. Caught between burning ships and a cavalry charge with no line of retreat, the Masters’ army disintegrated within minutes. Grey Worm’s Unsullied closed the trap from the landward side, leaving the coalition force with no avenue of escape.

Aftermath

Surrender of the Masters

With their fleet destroyed and their soldiers dead or scattered, the surviving Wise Masters surrendered to Daenerys directly. She executed the leaders who had broken the truce and spared lesser conspirators as a calculated show of mercy, cementing her control over Meereen and ending any organized slaver threat to the city for the remainder of her time in Essos.

Few battles in the war did more to determine the shape of the campaign that followed.
