The Duke of York, and about 2800 of his forces, were slain, amongst whom were William Bonvile, commonly called Lord Harrington; {58c} Sir David Hall, Sir Hugh Hastings, Sir John Mortimer, Sir Hugh Mortimer; Sir Thomas Neville, third son of the Earl of Salisbury; {58d} Sir Edward Bourchier, son of the Earl of Ewe (afterwards of Essex); Reginald Grey, the third son of Edward Lord Ferrers of Groby; and abundance of the gentry of the south of England. The Earl of Salisbury {58d} was wounded, taken prisoner, and sent the next day to Pontefract, and there beheaded, with some other persons of distinction; and their heads, with that of the Duke of York, were afterwards fixed on the gates or walls of York: that of the duke having a paper crown upon it, in derision of his claims to the throne. This act of barbarity is alluded to by Shakespeare, who attributes to Queen Margaret the expression, after the death of the Duke of York,— “Off with his head and set it on York gates So York may overlook the town of York.” {59a} The victory was closely followed by an act of shocking wickedness and barbarity. Edmund Plantagenet, Earl of Rutland, a son of the Duke of York, a boy only twelve years old, was captured when flying with his tutor from the field of battle, and was put to death near Wakefield Bridge, by Lord Clifford: a murder which obtained for him during the very short remainder of his life, the epithet of “the Butcher.” An extract from the act of attainder, which was passed after the accession of Edward IV. to the throne, against the Lancastrians, is interesting, as giving a list of such of them as took a part at the battle of Wakefield.
