, ca 1578 Francis Throckmorton (1554-1584) came from a prominent English Catholic family, his father
John Throckmorton being a senior judge and witness to
Queen Mary's will. While travelling in Europe with his brother Thomas from 1580 to 1583, they visited
Paris and met with Catholic exiles
Charles Paget and
Thomas Morgan. The Duke of Guise and Mary's supporters discussed ways forward. The
Ruthven Raid in Scotland was a setback. Cash to fund the plot and planned invasion ("the enterprise") became available after the death of
Antoinette of Bourbon, Duchess of Guise, in January 1583. After returning to London in 1583, Francis Throckmorton carried messages between Mary, Queen of Scots, Morgan, and
Bernardino de Mendoza,
Philip II of Spain's ambassador in London. This correspondence was routed through the French embassy in London. Throckmorton also carried some letters written by Mary to the French ambassador
Michel de Castelnau. An agent within the French embassy at
Salisbury Court near
Fleet Street, known as "Henry Fagot", notified
Francis Walsingham, Elizabeth's
Secretary of State. Throckmorton was taken into custody in November, along with incriminating documents, including lists of English Catholic supporters. He was encoding a letter to Mary, Queen of Scots when he was arrested. After a few days, he was taken to the
Tower of London. Another conspirator and letter carrier,
George More, was also arrested and questioned, but released after making a deal with Walsingham. Shortly before his arrest, Throckmorton managed to send a casket of other documents to Mendoza; it has been suggested this was exactly what Walsingham wanted him to do. Throckmorton was a relatively minor player, whose significance was to confirm the extent of Spanish involvement in seeking to overthrow Elizabeth. Protected by
diplomatic immunity, Mendoza was expelled in January 1584. Throckmorton was tortured with the
rack, first on 16 November, to ensure he revealed as much information as possible. On 19 November, he confessed to giving the Spanish ambassador a list of suitable havens and ports on the English coast. Throckmorton was put on trial on 21 May 1584 and executed on 10 July. His brother Thomas and many others managed to escape; some were imprisoned in the Tower of London, but Francis Throckmorton was the only one executed. ==Aftermath==
