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.

The letter
Sir Edward Stafford to Sir Francis Walsingham, Paris, 19 September 1586: a holograph despatch in clear English. DECODE catalogued it as a two-page cipher letter to an unknown recipient, dated London.
Where
British Library, Harley MS 1582 ff. 74–75; DECODE R8503, four images.
The cipher
Only four short runs on f. 74v (28 signs in all) are in cipher: letter signs with homophones, a null 6, and two-digit name codes.
How it was read
A contemporary hand wrote the decipherment above each run: “villequier”, “K. Navar”, “Kyll him and ye P. of Condé”, “D. Guise”. The glosses were checked sign by sign; run 1 spells villequier once the null is dropped.
What it says
Men of the Duke of Guise’s guard had sworn to kill the King of Navarre and the Prince of Condé. 47, 59 and 74 are name codes.
Still open
Nothing in the cipher. The letter is not in the Calendar of State Papers, Foreign.

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.

02 The four cipher runs

RunCiphertextGloss above itIn the sentence
1 (ll. 2–3)D x ◇ 6 ◇ 6 | Δ Ɗ X 6 · ⊕ 6 ꟷ ʃ ⊗villequier“with assurance that it is a letter of Villequier’s to come about Espernon”

4 (l. 13)74D. Guise“some of them of the guard of the Duke of Guise, who assure themselves to bring it to pass”

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.

English lines with short cipher runs and numbers, glossed above in a darker ink
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 …”. Image: British Library, Harley MS 1582 f. 74v, via DECODE R8503.

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.
