Rescue of Yara Greyjoy

"All of us chose to follow Yara. We left the Iron Islands for Yara. She would never leave one of us behind. We're not leaving her behind."

- Theon Greyjoy

The Rescue of Yara Greyjoy took place during the Great War when Theon Greyjoy set out to rescue his sister Yara, self-proclaimed Queen of the Iron Islands, from their uncle Euron, the King of the Iron Islands and an ally of Cersei Lannister.

Prelude
"Not for me. For Yara!"

- Theon, after rallying Yara's remaining loyalists

Near the end of the War of the Five Kings, Balon Greyjoy, who had declared himself King of the Iron Islands, was assassinated by his brother Euron Greyjoy. At the subsequent Kingsmoot where a king was chosen by the ironborn lords and captains, Euron was chosen as the next King over Balon's daughter Yara Greyjoy, who had the support of her younger brother Theon Greyjoy. While Euron was being crowned, Yara, Theon, and their loyalists stole 100 of the best ships of the Iron Fleet and fled the Iron Islands, sailing across the Narrow Sea to Meereen where they made a pact with Daenerys Targaryen, which had originally been Euron's plan.

During Daenerys Targaryen's invasion of Westeros, while Yara and Theon were sailing the Dornish back to Dorne, their fleet was suddenly assaulted by the Iron Fleet led by Euron Greyjoy, who had made a marital pact with Cersei Lannister. Euron's ironborn quickly overcame Yara's and Theon's, and while Theon was able to escape by jumping overboard, Yara was captured by Euron and later paraded through the streets of King's Landing.

Theon was rescued by the few survivors of Euron's attack and they returned to Dragonstone. Yara's remaining followers had lost total respect for Theon, seeing him as a coward for running. However, Theon was able to regain their respect after he beat Harrag, one of Yara's captains, to unconsciousness and declared that they would rescue Yara from Euron.

Yara, meanwhile, is held captive by Euron on his flagship, the Silence. When Yara asks why he hasn't killed her yet, Euron says it's because she's family (despite being a kinslayer) and because he enjoys talking to her rather than his tongueless, mute crew.

The rescue
While Euron Greyjoy is in the Red Keep with Cersei Lannister, Theon Greyjoy sneaks aboard the Silence docked in Blackwater Bay outside King's Landing with his men. They take out some of Euron's men as they make their way to where Yara is being held captive, tied to a post. Theon cuts her free, and Yara beats him to the ground, likely for abandoning her before, but helps him back up for rescuing her as she tried rescue him before. Together with their men, they escape the Silence.

Aftermath
Yara Greyjoy consolidates what remains of her fleet: three ships. She wants to sail back to the Iron Islands and take them back, but Theon decides to go to Winterfell in the North instead to help House Stark. Yara, as Theon's older sister and queen, allows him to do this, and the two embrace.

In the books
In the A Song of Ice and Fire books by George R.R. Martin, no equivalent event has occurred. Season 8 of Game of Thrones has surpassed the published books, so it is unclear if any similar event will occur in either of the remaining two books, The Winds of Winter and A Dream of Spring.
