Fawkes, who had 10 years of military experience fighting in the Spanish Netherlands in the failed suppression of the Dutch Revolt, was given charge of the explosives. The plot was revealed to the authorities in an anonymous letter sent to William Parker, 4th Baron Monteagle, on 26 October 1605. During a search of the House of Lords at about midnight

Rookwood and Catesby were described as "reasonably well", but Grant was blinded. Several of the conspirators disappeared into the night, but Rookwood, Catesby, the Wright brothers, Percy and Grant stayed on. They didn't have long to wait; by 11:00 am the next day the house was surrounded by 200 of the Sheriff of Worcester's men. In the ensuing battle, Wintour was shot in the shoulder. John and Christopher Wright were each killed.
