However, he supported Henry Bolingbroke on his return to England to become King Henry IV, only to be attainted (deprived of his Earldom because of a capital crime) for his role in the death of Thomas of Woodstock.
He then took part in the Epiphany Rising, a rebellion led by a number of Barons aimed at restoring Richard to the throne by assassinating King Henry IV; this quickly failed when the conspirators were betrayed by Edward of Norwich, 2nd Duke of York to Henry. After fleeing to the western counties, a number of the Epiphany Rising conspirators were captured and killed by mobs of townspeople loyal to the king; Despenser was captured by a mob and beheaded at Bristol on 13 January 1400.
