The Protestant rebellion of
Sir Thomas Wyatt in late January 1554 sealed Jane's fate, although she had nothing to do with it directly. Wyatt's rebellion started as a popular revolt, precipitated by the imminent marriage of Mary to the Catholic
Prince Philip (later King of Spain, 1556–1598). But Jane's father (the Duke of Suffolk) and other nobles joined the rebellion, calling for Jane's restoration as Queen. Philip and his councillors pressed Mary to execute Jane to put an end to any future focus for unrest. Five days after Wyatt's arrest the
execution of Jane and Guilford took place.
On the morning of
12 February 1554, the authorities took Lord Guilford Dudley from his rooms at the
Tower of London to the public execution place at Tower Hill and had him beheaded. A horse cart carried his remains back to the Tower of London, past the rooms where Jane remained as a prisoner. Jane was then taken out to Tower Green, inside the Tower of London, for a private execution. With few exceptions, private executions applied to royalty alone; Jane's private execution occurred on the orders of Queen Mary, as a gesture of respect for her cousin.
According to the account of her execution given in the anonymous
Chronicle of Queen Jane and of Two Years of Queen Mary, which formed the basis for
Raphael Holinshed's depiction, Guilford faced the block first, and from her lodgings at Partidge's house, Jane viewed his body being removed from the Tower Green. Upon ascending the scaffold, she gave a speech to the assembled crowd:
Good people, I am come hither to die, and by a law I am condemned to the same. The fact, indeed, against the queen's highness was unlawful, and the consenting thereunto by me: but touching the procurement and desire thereof by me or on my behalf, I do wash my hands thereof in innocency, before God, and the face of you, good Christian people, this day
She then recited the psalm
Miserere mei Deus (Have mercy upon me, O God) in English, and handed her gloves and hankerchief to her maid.
John de Feckenham, a Roman Catholic chaplain sent by Mary who had failed to convert Jane, stayed with her during the execution. The executioner asked her forgiveness, and she gave it. She pleaded the axeman, "I pray you dispatch me quickly". Referring to her blindfold, she asked, "Will you take it off before I lay me down?" and the axeman answered, "No, madam". She then blindfolded herself. Jane had resolved to go to her death with dignity, but once blindfolded, failing to find the block with her hands, began to panic and cried, "What shall I do? Where is it?" An unknown hand, possibly de Feckenham's, then helped her find her way and retain her dignity at the end. With her head on the block, Jane spoke the last words of Christ as recounted by
Luke: "Lord, into thy hands I commend my spirit!" She was then beheaded.
"The traitor-heroine of the Reformation", as historian AF Pollard called her, was merely 16 (or possibly seventeen) years old at the time of her execution. Apparently, Frances Brandon made no attempt, pleading or otherwise, to save her daughter's life; Jane's father already awaited execution for his part in the Wyatt rebellion. Jane and Guilford are buried in the Chapel of
St Peter ad Vincula on the north side of Tower Green. Queen Mary lived for only four years after she ordered the death of her cousin.
Henry, Duke of Suffolk was executed a week after Jane, on
19 February 1554. Merely three weeks after her husband's death and not even a month since her daughter's, Frances Brandon shocked the English court by marrying her chamberlain, Adrian Stokes. She was also fully pardoned and allowed to live at Court with her two surviving daughters. She is not known to have mentioned Jane ever again and was as indifferent to her child in death as she was in life.
