Burghley to Walsingham, 5 July 1572 (Harley MS 260)

At a glanceNot solved · text not obtained

The letter: Burghley to Walsingham, Westminster, 5 July 1572: clear English with one short ciphered passage about a rumour that the French King was pulling back from the Flanders enterprise.
Where: British Library, Harley MS 260 f. 262r–v, the fair-copy letter-book of Walsingham’s embassy; DECODE R8358, two images in reverse order.
The cipher: Boxed name codes [2], [3], [4], [5], a monogram, the single letters A and F, and a five-letter run “m o R. d A.”: 15 cipher tokens of 11 kinds.
How it was tried: Digges (1655) printed it with the codes left in cipher; CSP Foreign has neither letter; no key survives. The setting and Walsingham’s reply of 13 July identify [3] as the French King.
Still open: Of 15 cipher tokens, the 2 uses of [3] are identified; the rest are not deciphered. They need the lost key or a signed original with a clerk’s decipherment.

01 The record

Harley MS 260 is a fair-copy letter-book of Walsingham’s embassy in France, 1570–73, the book Digges printed from. DECODE R8358 has two images, in reverse order:

f. 262r (DECODE P2): the end of an earlier Burghley letter (“I am sorry for them, and so would you also yf you thought the suspicion to be true”), signed William Burleigh and addressed “To his very frend M^r Frauncis Walsingham Esquire Ambassador Resident for the Queenes Ma^tie in Fraunce”. Then the ciphered letter begins: “My Lord Ambassador, this day my Lord Admirall came to the Queenes speech”.
f. 262v (DECODE P1): the end of the letter, “From Westminster the 5^th of July 1572”, signed “Yo^r assured frend William Burleigh”. Then the address of Walsingham’s reply to Burghley, which begins “Your Lordship’s of the second and 5^th of July”.

02 The cipher

I am sorry that the opinion groweth here of the French King’s recoil from the Flanders enterprise; it breedeth coldness here. Some that are come home bear us in hand that [3] reneweth the m o R. d A. [4] whereby the last matter ⅋B [5] is hindered. I marvel much thereof; indeed [3] is more given to Milan [4] then to [2]. … I see no means by worldly means A but Florence with F. [2]; God send it some way.

English letter-book lines with boxed numerals and a few isolated letters and signs among the words — F. 262r: “some that are come home bear us in hand that [3] reneweth the m o R. d A. [4] whereby the last matter ⅋B [5] is hindered … indeed [3] is more given to Milan”. The boxed numbers and letters are the cipher items the copyist carried over; [3] is probably the French King (grade C); the rest is not deciphered. Image: British Library, Harley MS 260 f. 262r, via DECODE R8358.

Digges set the same passage as “[3 | reneweth the in o A. D. F. [4] whereby the last matter Bl5! is hindred … indeed 3| is more given to Millane 4] thentoſs|”. The transcription counts 15 cipher tokens of 11 kinds.

03 What was identified

[3] is the French King, Charles IX (grade C). Both uses come in the paragraph that opens with “the French King’s recoil from the Flanders enterprise”. Walsingham, writing from the French court on 13 July, answers: “I find the conjectures touching the [3] reneweth the … altogether false and vain, whereof I am assured of the contrary many ways”. Digges misprints “vain” as “Fain”.
“Milan [4]”. In this book a box written after a word marks a cover-name (see the November 1572 letter-book pages). So “Milan” is probably a cover-name, perhaps for Spain, and [4] its marker. This is not graded.

04 What was tried

Print. Digges 1655 prints both letters with the cipher as figures. CSP Foreign x, July 1572 (nos. 452–492), includes neither letter. The signed originals were not seen.
Keys. There is no key record from Harley 260 on DECODE. Tomokiyo’s survey of Elizabethan ciphers has no key for Walsingham’s Paris embassy. The Cecil–Norris table of 1568 already failed on a sibling group (Walsingham to Burghley, January 1573).
Siblings. Records R8356–R8364 from the same volume are being worked in this project. None of them holds a key or a gloss.
Context. Every token was regraded against the letter, the reply and the rule for cover-names. Only [3] is fixed.

05 What remains open

“m o R. d A.” is not deciphered. It is five letters of an unknown cipher, too short for cryptanalysis without a key. It is probably what [3] was said to “renew”.
[2], [4], [5], the monogram ⅋B, A and F are not deciphered. They need the lost key, or Burghley’s signed original with a clerk’s decipherment, if one survives in SP 70 or at Hatfield.
