Died: 1210

William did not accompany King Richard on Crusade but fought with King John against Philip of France in Normandy (1203/4). John demanded William as a hostage for his father's loyalty in 1208. His mother Maud refused and they fled to the family estates in Ireland. In 1210 John prepared an expedition to Ireland. Maud and William escaped Ireland but were apprehended in Scotland. (William the father was in Wales at this time.) It is believed by many writers that Maud and William were starved to death at Windsor Castle.

But even the earliest sources describing the deaths of Maud and William de Braose are divided as to whether the imprisonment took place at Windsor or Corfe. The most detailed account of their capture, imprisonment and death is given in the "Histoire des ducs de Normandie et des rois d'Angleterre". In this work the author states definitely that the deaths took place at Corfe, after eleven days imprisonment, and gives graphic details of the way the corpses were found.
