Correction note (2026-09-11)

This audit originally stopped at the accusation and did not state the trial’s outcome. It has been updated to add the Clerkenwell accusation (omitted from the original chronology), the Middlesex jury’s partial acquittal, the jurisdictional reason the Tower charge was never resolved, and Joanna Ferrour’s release on bail. These additions come from direct inspection of André Réville’s 1898 printed edition of the King’s Bench entries, carried out for the companion podcast episode “Joanna Ferrour and the Verdict That Stopped at the Tower.” No previously stated finding about her identification as the Tower assault’s leader has been withdrawn.

The Tower, 1381

Tower of London  ·  14 June 1381

Rebels stormed the Tower of London and beheaded the Archbishop of Canterbury and the Lord Treasurer. A future king, the boy Henry Bolingbroke, was inside and survived. Popular retelling credits his survival to a single figure, “John Ferrour.” The surviving court record names someone else as the assault’s chief leader, and it is not a man. No jury ever ruled on whether that particular accusation was true.

Claim tested

Who does the surviving King’s Bench record identify as the leader of the Tower assault, how does that square with the tradition crediting “John Ferrour” with saving the future Henry IV, and what did the court actually decide about the accusation against her?

Concise verdict

The King’s Bench indictment, read directly from André Réville’s 1898 printed edition, names Joanna Ferrour, not a man, as chief perpetrator and leader across three separate accusations: burning the Savoy Palace on 13 June 1381, burning the Hospital of St John at Clerkenwell on 14 June, and leading the group that stormed the Tower of London that same day, where it says she laid hands first on Archbishop Simon Sudbury and then on Robert Hales before both were beheaded. A Middlesex jury acquitted her on the Savoy and Clerkenwell charges. It never reached a verdict on the Tower charge. The reason given in Réville’s account of the proceedings is jurisdictional: the Tower stood within the city of London, not within Middlesex, and a Middlesex jury had no standing to rule on it. Joanna was released on bail, on the surety of four named men, to reappear once the court was better informed. No further record of that reappearance has been found. Separately, a tradition holds that a John Ferrour, understood to be her husband, was later pardoned by Henry IV specifically for having saved his life in the Tower during the same assault. Popular retellings tend to fold these into a single male figure, which the court record does not support, and typically stop at the accusation without stating that the Tower charge itself was never resolved.

Why this claim matters

The Peasants’ Revolt’s best-attested female leader has been substantially erased from popular memory of one of its most dramatic single episodes, while a male figure with a thinner documentary trail has absorbed the story. This is not a case of the record being silent and later tradition filling the gap. The record is specific and names her directly, across three separate incidents. The second erasure is quieter: even accounts that do name her tend to treat the case as settled, either as a clean acquittal or an implied conviction, when the surviving record does neither. The single most serious charge against her was left open, not resolved, and stayed that way in every document located for this audit.

Chronology

13 JUNE 1381

Rebels, including a group from Kent, burn the Savoy Palace, the London residence of John of Gaunt, Duke of Lancaster. The indictment accuses Joanna Ferrour of coming to the Savoy as chief perpetrator and leader of that company, and of seizing a chest containing more than £1,000 of the Duke’s money and dividing it with others in Southwark.

14 JUNE 1381 — MORNING

The indictment’s second accusation: Joanna, as head of the company, went to the Hospital of St John of Jerusalem at Clerkenwell, the English headquarters of the Knights Hospitaller, set a fire, and burned the house.

14 JUNE 1381 — AFTERNOON

While Richard II is away from the Tower negotiating with rebels at Mile End, a separate rebel group enters the Tower of London, reportedly with minimal resistance. Archbishop Simon Sudbury and Lord Treasurer Robert Hales, along with a friar and a royal sergeant, are seized and beheaded on Tower Hill, the first recorded execution there. The young Henry Bolingbroke, son of John of Gaunt and the future Henry IV, is in the Tower at the time and survives. The indictment’s third and most serious accusation names Joanna as chief leader of the group, and says she laid hands first on Sudbury and then on Hales before they were dragged out and beheaded.

TRIAL AND AFTERMATH, DATE NOT ESTABLISHED

Joanna is arrested, committed to the Marshalsea, and pleads not guilty before the King’s Bench. A jury drawn from Middlesex acquits her on the Savoy and Clerkenwell accusations but does not reach a verdict on the Tower accusation. Réville’s account of the proceedings attributes this to jurisdiction: the Tower stood within the city of London, outside the authority of a Middlesex jury. Joanna is released on the surety of four named mainpernors, ordered to reappear at the octave of St Hilary. No King’s Bench entry recording that reappearance, if it occurred, has been located in the material examined for this audit, and the Tower accusation remains unresolved on the current evidence. Separately, a John Ferrour, understood in one tradition to be her husband, is later granted a royal pardon by Henry IV explicitly acknowledging that Ferrour had been instrumental in saving the king’s life in the Tower on 14 June 1381.

Source hierarchy

André Réville’s 1898 printed edition of the King’s Bench Rex-side entries (Le soulèvement des travailleurs d’Angleterre en 1381, Appendice II, Série A, document 13), read directly for this audit, is treated as Tier 1 primary evidence for the indictment’s wording and the trial’s outcome. Sylvia Federico’s published translation (2001) is treated as a corroborating scholarly translation of the same entry. The Henry IV pardon tradition crediting John Ferrour is treated as a separate, later-attested claim, not yet cross-checked against a specific enrolled pardon for this audit. Chronicle accounts of the Tower’s fall are treated as near-contemporary narrative.

Provenance assessment

This audit now rests on direct inspection of Réville’s printed edition of the relevant King’s Bench entries, rather than on Federico’s translation alone; the manuscript itself (TNA KB 27/482) has not been independently inspected for this audit. The relationship between Johanna and John Ferrour, understood as husband and wife in the sources consulted, has not been confirmed against a primary genealogical or legal record establishing the connection directly. The specific regnal year in the Michaelmas-term citation is uncertain from the scan consulted, between Richard II’s third and seventh years; this does not affect the trial-outcome finding, which is stated independently of that digit.

Contradiction table

A dossier does not smooth over conflicts in the record. Where sources disagree, or where popular retelling and the record diverge, the disagreement is stated, not resolved by preference for the more commonly repeated version.

Point of fact Popular retelling King’s Bench record Status
Identity of the assault’s chief leader Commonly given as “John Ferrour” Names Johanna Ferrour as chief perpetrator and leader Contradicted
Who saved Henry Bolingbroke Often merged into the same “Ferrour” figure as the Tower leader Pardon tradition credits John Ferrour specifically, a separate individual from Joanna in the sources consulted Unconfirmed / likely conflated
Outcome of the Tower accusation against Joanna Ferrour Usually left unstated, or assumed to end in acquittal along with the rest of the case Never brought to a verdict; reserved for want of Middlesex jurisdiction; Joanna released on bail to reappear, with no further record found Unresolved in the record

Evidential classification

Claim Classification
Sudbury and Hales were seized and beheaded at the Tower on 14 June 1381Supported
Johanna Ferrour is named in the King’s Bench record as chief perpetrator and leader across the Savoy, Clerkenwell and Tower accusationsSupported (Réville 1898, read directly; corroborated by Federico’s translation)
“John Ferrour” was the assault’s chief leaderUnsupported (the leadership role is documented for Johanna, not a male Ferrour)
A Middlesex jury acquitted Joanna Ferrour on the Savoy and Clerkenwell accusationsSupported (Réville, Appendice II, document 13)
Joanna Ferrour was acquitted, or was convicted, of the Tower accusation specificallyContradicted (the record shows no verdict reached on this charge; she was released on bail, not cleared or convicted)
Henry Bolingbroke’s survival was owed to a Ferrour’s interventionProbable but unresolved (credited to John Ferrour in the pardon tradition; not yet cross-checked against an enrolled pardon)

What can safely be said

“The King’s Bench record names Johanna Ferrour, not a man, as chief perpetrator and leader of the rebel companies that burned the Savoy Palace on 13 June 1381, burned the Hospital of St John at Clerkenwell on 14 June, and stormed the Tower of London that same day, where it says she laid hands on Archbishop Sudbury before he and Lord Treasurer Robert Hales were beheaded. A Middlesex jury acquitted her on the Savoy and Clerkenwell charges. It never reached a verdict on the Tower charge, reserved because the Tower lay outside the jury’s jurisdiction, and she was released on bail to reappear at a later date. No further record of that appearance has been found. Popular retellings crediting a single ‘John Ferrour’ with these events, and separately with saving the future Henry IV’s life, appear to conflate two documented individuals, and typically omit the trial’s divided outcome altogether.” This is directly supportable from Réville’s printed edition of the King’s Bench entries, corroborated by Federico’s translation.

Unresolved evidence gaps

The KB 27 manuscript has not been independently inspected for this audit; the trial-outcome finding rests on Réville’s printed edition, corroborated by Federico’s published translation. What became of the Tower accusation after Joanna’s ordered return, at the octave of St Hilary, has not been established; no further King’s Bench entry disposing of it has been located. The specific enrolled pardon to John Ferrour has not been located and checked directly. Whether Johanna and John Ferrour were in fact married, as the secondary sources consulted assume, has not been confirmed against a primary record establishing that relationship.
