This episode of the History Extra podcast delves into the dramatic collapse of the Gunpowder Plot of 1605. Host Danny Bird and historian Professor John Cooper reconstruct how the infamous conspiracy was foiled—from the unmasking of Guy Fawkes beneath Westminster, to the last stand of the remaining plotters, to the public trials and gruesome executions. The episode also explores the political and religious aftermath, examining not just what happened, but why these events left such an indelible mark on English memory.

Key Discussion Points & Insights

The Origins & Revelation of the Plot

The Monteagle Letter and Its Significance

• In late October 1605, Lord Monteagle, a Catholic peer, receives a mysterious letter imploring him to avoid Parliament on 5 November.
• The letter “blows the existence of the Gunpowder Plot” into the open, serving either as an act of mercy or, as conspiracy theorists suggest, government fabrication to justify further anti-Catholic measures.
• Most historians attribute the letter to Francis Tresham, “the Judas Iscariot of the plot,” who likely wanted Monteagle spared, or perhaps to trigger the plot’s exposure.
  • “The most likely writer of that letter is Francis Tresham, the sort of 13th man of the Gunpowder Plot, the Judas Iscariot of the plot...” (Professor Cooper, 02:11)

How Far Did the Plot Advance?

• Authorities had early suspicions, with government agents tracking leading figures months in advance.
• A delay follows the Monteagle letter before King James is informed, suggesting the government may have allowed the plot to unfold.
• Two searches of the Palace of Westminster occur:
  • The first finds Guy Fawkes—alias John Johnson—minding a suspicious pile of firewood.
  • The second, reportedly ordered directly by James I, exposes 36 barrels of gunpowder and leads to Fawkes’s arrest.
  • “It’s almost sort of divine revelation that James thinks, oh, that sounds strange. I’m going to order this second search.” (Professor Cooper, 05:43)

Acquisition of Gunpowder

• Acquiring 36 barrels was feasible due to the prevalence of gunpowder in early-17th-century England.
• Catesby and Winter’s military backgrounds facilitated procurement through army contacts or London’s bustling port.
• “The acquisition of the gunpowder was probably not the biggest problem that the plotters were facing.” (Professor Cooper, 07:33)

The Capture and Interrogation of Guy Fawkes

Circumstances of Arrest

• Guy Fawkes is arrested disguised, armed with fuses ("matches"), priming tubes, and a lantern—suggesting he planned to ignite the powder before fleeing.
• Fawkes was likely intending to light the fuse and escape to alert other conspirators, not die in a suicide blast.
  • “He’s found with riding boots and spurs...the implication is...he would have lit the fuses and then quietly backed out of that cellar.” (Professor Cooper, 09:15)

Torture and Confession

• Subjected to both “manacles” and the “rack,” Fawkes withstands torture for days before divulging information, not immediately betraying his confederates.
• The authorities focus on extracting names of co-conspirators rather than proving Fawkes’s guilt, as his intent was clear.
  • “Guy Fawkes knows that his life is forfeit...what he can do is delay long enough that other members of the plot could perhaps ignite the other half of the plot...” (Professor Cooper, 10:50)

The Midlands Uprising and the Final Stand

• Upon hearing of Fawkes’s capture, the plotters attempt to spark an uprising among the Midlands’ Catholic gentry, hoping to seize Princess Elizabeth and place a Catholic monarchy.
• Their hope collapses as the truth of the failed explosion spreads, leaving them no support.
• The plotters make a doomed, “almost western style last stand,” dying in a gun battle.
  • “They decide to fight it out...a gun battle at an English country house in which Catesby is killed and Thomas Winter is badly wounded.” (Professor Cooper, 13:43)

The Role of Princess Elizabeth

• Princess Elizabeth, aged nine, was chosen as a puppet Catholic monarch if the plot succeeded—not due to her sympathies, but her malleability and precedence of child sovereigns.
• “She would have been a figurehead...the expectation would be that it would be a new Catholic regime, sort of headed by that Catholic nobleman, but nominally carried out in the name of Queen Elizabeth.” (Professor Cooper, 15:23)
• Gendered thinking and uncertainties about Prince Charles’s health helped shape this choice.

Trials as Propaganda

Public Spectacle and State Authority

• The plotters are tried in Westminster Hall—the site they aimed to destroy. Trials are “show trials”, designed as public spectacle to reinforce the king’s authority and God’s providence.
• The government swiftly spins the failed plot into a narrative of divine deliverance, propagandized via sermons, pamphlets, church services, and engravings.
  • “The trial...becomes part of a big sort of propaganda campaign...” (Professor Cooper, 22:59)
• The tradition of bonfires (“Bonfire Night”) begins almost immediately as both state-directed propaganda and spontaneous local relief.

Punishments and Executions

• Surviving plotters suffer “the full horrors of a traitor’s death” (hanging, drawing, and quartering), publicly detailed with “enormous gleeful detail” by officials.
• Guy Fawkes—tortured and weakened—evades this slow death by jumping from the scaffold to break his neck.
  • “He cheats the executioner...it shows his presence of mind, it shows his extraordinary bravery.” (Professor Cooper, 26:19)

Aftermath and Legacy

Political and Religious Consequences

• The failed plot provides an excuse for anti-Catholic policies, revoking hopes for religious toleration and strengthening measures against Catholics.
• James I is personally shaken by the close call, his caution reinforced by the failed assassination attempt and deepening his suspicion of both Catholics and Parliament.
  • “Any ideas of toleration of Catholics really have gone from his head. And he is deeply shocked by this.” (Professor Cooper, 29:00)

Notable Quotes & Memorable Moments

• On the letter’s identity:
  “If you’re in the mind of a conspiracy theorist, it could be that the letter itself is fabricated by the government...not, I think, a completely plausible line of interpretation.”
  — Professor Cooper (02:14)

• On Guy Fawkes’s character:
  “He’s a psychologically complex man. I don’t think it’s impossible to believe that this was a suicide mission. And he’s got nerves of steel.”
  — Professor Cooper (08:56)

• On the enduring resonance of the plot:
  “It doesn’t just all sort of fizzle out...the remaining plotters...make this dramatic, almost western style last stand.”
  — Professor Cooper (13:58)

• On Elizabeth’s role:
  “She wouldn’t, I think, easily have fallen in with a Catholic conspiracy that had blown up her father and her brother.”
  — Professor Cooper (15:08)

• On the tradition of Bonfire Night:
  “Bonfires start being lit in London...that tradition...begins right at the discovery.”
  — Professor Cooper (24:44)

• On Guy Fawkes’s execution:
  “Somehow...he manages to summon the physical strength to jump and he breaks his neck immediately. So it’s an instant death for Guy Fawkes.”
  — Professor Cooper (26:30)

Professor Cooper’s explanations strike a balance between debunking myths and embracing the enduring drama of the story. The focus remains on unfolding events logically, not simply recounting familiar facts.
