The new leadership, eventually headed by
Hugh le Despenser, 1st Earl of Winchester, and his son
Hugh Despenser the Younger, proved no more popular with the baronage, and in 1321 Lancaster was again at the head of a rebellion. This time, he was defeated at the
Battle of Boroughbridge on 16 March 1322 and taken prisoner. Lancaster was tried by a tribunal consisting of, among others, the two
Despensers;
Edmund Fitzalan, 9th Earl of Arundel; and King Edward. Lancaster was not allowed to speak in his defence, nor was he allowed to have anyone speak for him. He was convicted of treason and sentenced to death. Because of their kinship and Lancaster's royal blood, the king commuted the sentence to beheading, as opposed to being
hanged, drawn and beheaded, and Lancaster was executed on 22 March 1322 near
Pontefract Castle. Upon his death, his titles and estates were forfeited, and the Scots, whom Lancaster gained aid from in his rebellion, mainly to weaken the English in their war, seized the opportunity to take his inheritance in the
Great Raid of 1322. In 1323, his younger brother
Henry successfully petitioned to take possession of the earldom of Leicester, and in 1326 or 1327, Parliament posthumously reversed Thomas's conviction. Henry was further permitted to take possession of the earldoms of Lancaster, Derby, Salisbury and Lincoln. Soon after Thomas's death, miracles were reported at his tomb at Pontefract, and he became venerated as a
martyr and
saint. In 1327, the Commons petitioned
Edward III to ask for his
canonisation, and popular veneration continued until the reformation. In 1822, it was alleged that Thomas's remains had been discovered on Monday 25 March of that year, in a large stone coffin buried in a field in the parish of
Ferry Fryston (precisely five hundred years after his execution and precisely one week before
April Fools' Day). This story was syndicated in
stereotype in the
first week of April, credited to "the
Leeds Mercury of Saturday last" (i.e. 30 March 1822); in the second week of April syndicated in a new stereotype without crediting the
Mercury (and paired with an apparently true story about the February discovery in
Capelle of a "fossil ship"); and then disappeared from the public eye. In 1942, E. J. Rudsdale wrote that he had encountered a box of bones, labeled as Thomas's and as having been "removed from
Pomfret Castle" in 1885, at Paskell's auctioneers in Colchester, Essex. == Titles and lands ==
