Plot to rescue Mary and send her to Flanders

The plot to rescue Princess Mary Tudor and send her to Flanders was a covert effort to remove her from a court increasingly hostile to her, before her defiance of Henry VIII could be turned into a capital charge. Margaret Pole and her allies assembled transport, contacts, and information, but arrests across the court and household severed the means of carrying out the escape. The plan ends not with Mary’s departure, but with its organizers forced to wait as the danger around her grows.

Background and Urgency

The immediate concern was that Henry VIII’s treatment of Princess Mary Tudor had become more threatening. Jane Seymour spoke in Mary’s favor, and Thomas Cromwell advised that she should come to court; Henry, however, was reported to have shouted that she should be tried for treason and condemned Jane for advocating on her behalf. To Margaret and Montague, the king’s hostility made Mary’s continued presence in his kingdom dangerous. They feared that her existence reminded him of her mother and of the marriage he had repudiated, while her refusal to yield intensified the conflict.

The threat did not seem confined to the princess. Margaret was shaken by the news that Henry could accuse a niece he loved of treason and place her in the Tower of London under sentence of death. If that could happen to the king’s niece, Margaret reasoned, his daughter was also vulnerable—especially when he treated Mary as illegitimate and sent men to threaten her. The rescue plan thus arose from a political calculation: a royal relationship offered no reliable protection once the king chose to define an act as treason.

Preparations for Escape

The preparations were practical and distributed among trusted people. Geoffrey rode to the riverside village of Grays and confirmed that a boatman was ready to leave when called. The boatman remained loyal to Princess Mary Tudor, giving the plan a possible means of departure by water. The arrangement depended on secrecy and readiness rather than a publicly visible journey.

A second route of support ran through Calais. Arthur Plantagenet, Viscount Lisle, wrote to Margaret that he could receive the consignment she was preparing to send. A message to his steward in London would alert him when it was due. The correspondence established a receiving point across the water, while the proposed consignment provided a discreet framework for communication and delivery. The evidence describes these arrangements, but does not say that Mary herself reached Calais or that the goods were delivered.

Montague brought six strong riding horses to court, explaining that he was training them for the hunting season. Their presence offered another practical resource without openly announcing its purpose. Meanwhile, Henry Courtenay obtained information from a stable boy at Hunsdon, where Mary was being kept. He learned that she was now permitted to walk in the garden each morning for her health. The detail gave the plotters a clearer picture of her circumstances, but also showed how much their knowledge depended on paid access to people inside the household.

Arrests and Exposure

That fragile network began to collapse as the authorities moved against people associated with Mary. Margaret first heard that Sir Anthony Browne, the king’s trusted Master of Horse, and Sir Francis Bryan had been arrested for treason. Their arrests shocked the court because both were counted among Henry’s firm friends. The charge exposed the precariousness of courtly favor: service and intimacy with the king did not prevent a sudden accusation.

Thomas Howard told Margaret that the two men had conspired with Princess Mary Tudor, plotting to remove her from Hunsdon and send her by ship to Flanders. He said he would have them hanged and threatened the same punishment for Mary. The rescue effort was thereby named as a treasonous conspiracy, and the danger it was designed to avert became explicit. Margaret concealed this account from the queen’s ladies, limiting what she said even among people close to her.

The investigation spread beyond Browne and Bryan. Thomas Cheyney and John Russell were taken for questioning on suspicion that they had encouraged Mary to defy her father. Nicholas Carew was arrested as well. Anne Hussey, a friend who had served Mary in Margaret’s household, was arrested for plotting and taken to the Tower of London. Henry Courtenay was dismissed from the Privy Council under suspicion of plotting for the princess, as was William Fitzwilliam, though Montague later clarified that Courtenay had not been arrested. The distinction between arrest, questioning, and dismissal mattered, but each action narrowed the circle of people able to help.

The Plan Stalls

By the time Montague reported back to Margaret, the practical routes out of Hunsdon had been blocked. Courtenay’s man had disappeared from the stables, removing one link to the household. The person with access to Mary’s door was no longer available, and Carew’s paid maid could not be reached while Carew was under arrest and his whereabouts unknown. With those contacts lost, there was no one able to open the way for Mary to leave. Montague concluded that they would have to wait.

The failure is a suspension rather than a completed escape: the evidence confirms the preparations, the arrests, and the loss of access, but not Mary’s rescue or departure for Flanders. The episode shows how a plan assembled through separate channels—a boatman at Grays, correspondence through Calais, horses at court, and information from Hunsdon—could be undone by the removal of its human links. It also turns the plot into a measure of the political climate around Mary: even a proposed journey to safety could be treated as treason, and association with her placed friends and servants at risk.
