Guy Fawkes was a member of a group of provincial English Catholics who planned the failed Gunpowder Plot of 1605. Fawkes fought in the Eighty Years' War on the side of Catholic Spain against Protestant Dutch reformers. He later met Thomas Wintour, with whom he returned to England. Wintour introduced Fawkes to Robert Catesby, who planned to assassinate King James I and restore a Catholic monarch to the throne. The plotters secured the lease to an undercroft beneath the House of Lords, and Fawkes was placed in charge of the gunpowder they stockpiled there. Prompted by the receipt of an anonymous letter, the authorities searched Westminster Palace during the early hours of 5 November, and found Fawkes guarding the explosives. Over the next few days, he was questioned and tortured, and eventually he broke. Immediately before his execution Fawkes jumped from the scaffold where he was to be hanged and broke his neck, thus avoiding the agony of the mutilation that followed.
