Siege of Riverrun

With the Red Wedding settled in favor of the Iron Throne, the riverlords surrendered one after another. Riverrun alone refused.

House Lannister allied with the Freys to stamp out that last pocket and hand the castle to Ser Emmon Frey, as their pact required.

Ser Daven Lannister, the new Warden of the West, took command of the siege. Brynden Tully, meanwhile, had emptied the castle of useless mouths and gathered what grain and livestock he could before shutting the gates.

Ser Ryman Frey brought Lord Edmure, held captive at the Twins, to the camp and threatened to hang him unless Riverrun yielded. He never carried it out, and the siege dragged on.

Ser Jaime Lannister arrived with reinforcements and relieved Ryman Frey of command. He had Edmure brought before him and laid out, plainly, what awaited him if the troops took the castle by force.

Edmure agreed to speak with his uncle, and the next day he surrendered Riverrun — but not before letting Ser Brynden slip away.

Edmure was sent to Casterly Rock as a prisoner for life, with hope of being reunited there with his wife and newborn child. Jeyne Westerling, Robb Stark's widow, traveled with him.

Ryman Frey was found hanged shortly after, killer unknown. House Frey of Riverrun kept the castle, and Jaime rode on to Raventree Hall to settle the Blackwood-Bracken feud.

The show tells a different ending. Jaime Lannister arrives to take command of the siege while Walder Frey pushes for an assault on the Tully castle.

The castle falls after an assault in which Ser Brynden Tully dies, and Riverrun passes into Frey hands.
