Stafford to Walsingham, Paris, 19 September 1586

British Library, Harley MS 1582 ff. 74–75 (DECODE R8503). DECODE lists it as a letter of Sir Edward Stafford to an unknown recipient, partially decrypted. It is his holograph despatch to Walsingham in clear English, with four short cipher runs on f. 74v. Each run was deciphered between the lines when the letter arrived. Every sign of the runs was transcribed and checked against that decipherment, which also gives the letter values of the key.

Summary. DECODE catalogues R8503 as a two-page cipher letter from Sir Edward Stafford to an unknown recipient, dated London, 19 September 1586. The four images show something else: a holograph despatch in clear English, dated “Paris this 19th of September 1586”, signed by Stafford and addressed on f. 75v to Sir Francis Walsingham, Principal Secretary. Only four short runs on f. 74v are in cipher, 28 signs in all. A contemporary hand has written the decipherment above each run: “villequier”, “K. Navar”, “Kyll him and ye P. of Condé”, “D. Guise”. Together they give a warning that men of the Duke of Guise’s guard had sworn to kill the King of Navarre and the Prince of Condé. We checked the glosses sign by sign. Run 1 spells villequier across a line break once the null 6 is dropped, and run 3 spells kyll with the same letter signs, so the glosses are exact. 47, 59 and 74 are name codes. The letter is not in the Calendar of State Papers, Foreign, because Harley manuscripts fall outside the State Papers. Nothing stays open.

01 The record

DECODE R8503 has four images: f. 74r, f. 74v, f. 75r (blank) and f. 75v (address leaf). The address, written upside down, reads “To the right honorable Sir Francis Walsingham knight, her Majesty’s principal secretary”, and the endorsement reads “19 Sept. 1586. From Sr Edw: Stafford”. So DECODE’s “unknown recipient” is Walsingham. Its “London” is where the manuscript is kept: the letter was written in Paris, where Stafford was ambassador.

The despatch is Stafford’s news of the court, a month after the Babington plot was uncovered. F. 74r covers the stir in England over a false report, the King of France and the Queen of Scots, Mendoza, and “that vile traitor Charles Paget”, who went to the Capuchins to speak with the King. F. 74v covers the copy of a letter about Épernon, a plot against Navarre, and the Queen Mother’s new powers to treat with the King of Navarre on the point of religion.

The glosses are in a darker ink than the letter and are written in a different hand, which suggests Walsingham’s secretariat. The words between the runs are Stafford’s clear text as it reads on the page. They are quoted to show the sense and not transcribed letter for letter.

F. 74v, runs 2–4: 47 glossed “K. Navar”, the run glossed “Kyll him and ye P. of Condé”, and 74 glossed “D. Guise”, in Stafford’s clear sentence “… dispatched to kill him and the Prince of Condé, whereof some of them of the guard of the Duke of Guise …”.

03 The cipher

Stafford mixed an alphabet of letter forms and graphic signs with two-digit codes for persons. The glosses give these values:

Run 3 confirms the values from run 1 independently: the same x and ◇ stand for the y and l of kyll, and 47 recurs there as “him”, meaning Navarre. No key sheet for Stafford’s cipher with Walsingham has been found. S. Tomokiyo’s survey of Elizabethan ciphers (Cryptiana) notes only that Stafford used different ciphers with Walsingham and with Burghley, and that he sent Walsingham names to add to his.

04 What remains open

Nothing in the cipher. All 28 signs are accounted for. The only value taken from the gloss without a check at letter level is ω ʒ ϖ = “and” (grade C: it fits the sense and the gloss, but no other occurrence confirms it). The clear text of the despatch was consulted for context but not transcribed in full.
