Siege and surrender: book six in the crown of blood series - Siege of Fort Zeelandia - Wikipedia

The siege of Riverrun takes place near the end of War of the Five Kings . Ser Brynden Tully is besieged at Riverrun by the combined forces of House Lannister and House Frey in an effort to remove House Tully and install the newly-raised House Frey of Riverrun .

After the Red Wedding and the death of Robb Stark , King of the Trident , the river lords offer terms to the Iron Throne and support for the Stark - Tully kingdom slips away. House Lannister, supported by their new allies, House Frey , besiege Riverrun in an effort to remove the final vestiges of resistance in the riverlands and install Ser Emmon Frey as the new Lord of Riverrun, as the terms of the alliance between the Freys and Lannisters dictate. Ser Daven Lannister , the new Warden of the West , is sent to command the siege. [2] Ser Ryman Frey marches two thousand Freys to Riverrun. [1]

Ser Brynden Tully , Robb's Warden of the Southern Marches , anticipates the siege. He gathers all the foodstuffs and goods he can within the castle, expels all the unnecessary mouths, and prepares for a long siege. [4]
