British Library, Harley MS 260 ff. 398–399 (DECODE R8363), a later copy in Walsingham’s Paris letter-book. DECODE lists it as “Frauncis Walsingham? to …, 21 Jan 1572, short parts encrypted only”. The images show a clear letter to the Lord Treasurer with a single ciphered place name. The group was transcribed but not deciphered: no key survives, and with the one group in Burghley’s reply it is too short for cryptanalysis. No earlier decipherment is known.

Summary. The record holds the end of Walsingham’s letter of 21 January and all of a second letter, to Burghley, dated “At Paris the xxth of Januarie 1572”, that is 20 January 1573 in the new-style year. The second letter is in clear English except for one passage: “a Gentleman of [9] departed hence to 2 1 ⌘ ε 9 4 with intention to imbarke there yf the barke were not departed”. The bracketed [9] is a mark the copyist uses wherever he left a cipher name out, so it carries no cipher. The six symbols name a port. Dudley Digges printed the letter from this book in The Compleat Ambassador (1655, p. 313) and set the group in cipher type without a decipherment. The Calendar of State Papers Foreign summarises a letter of the same day (no. 725) that opens with the same matter but has no cipher passage. No Walsingham–Burghley key of 1572–73 is on DECODE or in Tomokiyo’s survey, and the Cecil–Norris table of 1568 gives nonsense. One more group in the same system, in Burghley’s reply (R8364), gives twelve symbols in all. That is too few: Dieppe, Calais, Nantes and other six-letter ports all fit. The group is not deciphered.

01 The record

Harley MS 260 is a fair-copy letter-book of Walsingham’s embassy in France, 1570–73, the book Digges printed. DECODE R8363 has three images:

02 The cipher

The whole of the cipher is the last two lines of f. 398r:

The matter of most importance conteyned in the same was touchinge a Gentleman of [9] departed hence to 2 1 ⌘ ε 9 4 wth intention to imbarke there yf the barke were not departed.
Four lines of English letter-book hand, the last two with a bracketed flourish and six cipher signs
F. 398r, last lines: “… a Gentleman of [9] departed hence to 2 1 ⌘ ε 9 4 wth intention to imbarke there”. The bracketed [9] stands for a name the copyist left out; the six symbols, a port, are not deciphered. Image: British Library, Harley MS 260 f. 398r, via DECODE R8363.

The copyist writes [9], a bracketed flourish, wherever the original had a cipher name he did not copy. It stands for other names in R8362 (“longeth to heare from Lyons [9]”) and R8364, and Digges prints it as “[7]” or “[s]”. The six symbols 2 1 ⌘ ε 9 4 were copied, and Digges set them as “2 ) ⌘ 6·) 4”. Burghley’s answer in the same book (f. 419r, DECODE R8364, February 1572/3) has one group in the same system: “a Shipp sent to 2 0 ⌘ H 6 1 tt ymagined that Ball there had a meaninge to provoke Glasco [9] to come hither”. Both groups start with 2 and have ⌘ third.
