 Catesby proposed to blow up "the Parliament House with gunpowder", killing the king and his government, as in "that place, have they done us all the mischief".Catesby had not then given up hope on foreign help, and so he sent Wintour to the continent to meet with the Constable of Castille.Wintour also met with Welsh spy Hugh Owen, who introduced him to Guy Fawkes, a man with whose name Catesby was familiar.
