Capture of Winterfell
From A Wiki of Ice and Fire
After [[Rodrik Cassel] took most of the guards from to relieve the siege by the Ironmen at Torrhen's Square, Theon Greyjoy descended on the few remaining guards with only twenty men, storming the castle at night and conquering the mighty castle with ease. Theon declared himself the Prince of Winterfell and took Ramsay Bolton, in the disguise of "Reek", as a retainer. Bran Stark,Rickon Stark, Little Walder Frey, Big Walder Frey,Meera Reed, Jojen Reed and Beth Cassel were all kept as hostages. However, Brandon, Rickon, Jojen and Meera escaped. To avoid embarrassment, Theon had Ramsay kill two boys in place of the Starks and announced to the world that they were dead.
