The Westfold was a region of Rohan that was east to the Gap of Rohan and contained Helm's Deep. It bordered with the Eastfold via the Snowbourn River.
Erkenbrand rode with Gandalf to Helm's Deep to relieve Theoden's battered army.
During the war of the ring the Westfold was attacked by Isengard and the men of Dunland and several villages were burned down.
