The Queen of England, Margaret of Anjou, refused to accept an arrangement that deprived her son—Edward of Westminster—of his birthright. She had fled to Scotland after the Yorkist victory at Northampton; there she began raising an army, promising her followers the freedom to plunder on the march south through England. Her Lancastrian supporters also mustered in the north of England, preparing for her arrival. York marched with his army to meet this threat but he was lured into a trap at the Battle of Wakefield and killed. The duke and his second son, Edmund, Earl of Rutland were decapitated by the Lancastrians and their heads were impaled on spikes atop the Micklegate Bar, a gatehouse of the city of York. The leadership of the House of York passed to the duke's heir, Edward.
