Gunpowder Plot [SEP] Executions
Although Catesby and Percy escaped the executioner, their bodies were exhumed and decapitated, and their heads exhibited on spikes outside the House of Lords. On a cold 30 January, Everard Digby, Robert Wintour, John Grant, and Thomas Bates, were tied to hurdles—wooden panels—and dragged through the crowded streets of London to St Paul's Churchyard. Digby, the first to mount the scaffold, asked the spectators for forgiveness, and refused the attentions of a Protestant clergyman. He was stripped of his clothing, and wearing only a shirt, climbed the ladder to place his head through the noose. He was quickly cut down, and while still fully conscious was castrated, disembowelled, and then quartered, along with the three other prisoners.
