- The letter
- A writer in Henrietta Maria’s household at Paris to Charles I, January [1646]. Signed with the number 385.
- Where
- The National Archives, Kew, SP 106/10 ff. 235–236; DECODE R924. It was part of catalogue item 59, which grouped six letters in four different keys.
- The cipher
- One- and two-digit numbers for letters, up to four for a vowel, and a numbered word list from 100 up, roughly in alphabetical order (100 all, 108 and, 141 for).
- How it was deciphered
- George Lasry reconstructed the key (“TNA SP106-8”) and deciphered the letter on DECODE in October 2020. His plaintext is the text; it stays on DECODE as his work and is not in this repository, so the reading audit of 22 October 2026 counted the letter as decoded, not read. On 23 October his files were fetched and the letter decoded afresh; with four code values set by sense it builds most sentences, but counting those as holes it stays just under the reading bar, so it is still decoded, not read. Applied here group by group, his key gives his text on every line that can be compared.
- What it says
- The writer argues against sending Sir H. Compton as ambassador and against the treaty for Prince Charles’s marriage with Portugal. He reports on Montreuil’s mission and on levies of five or six thousand men.
- Still open
- 58 three-digit numbers not in Lasry’s word list and 11 low figures with no value in the key: 162 groups in all.
- Other keys
- The five other letters once filed with it are in different ciphers: R785, R790, R923 (TNA SP 106), R787 (SP106-2), R929 (SP106-5).
01 The letter and the key
Catalogue item 59 grouped six cipher letters of SP 106/10 from Henrietta Maria’s household in France to Charles I. George Lasry reconstructed four keys for the run, and on 14 October 2026 the entry was split so that each page presents one key. This letter is the only one of the six in his “SP106-8” key, dated January 1646. In his files the same key also covers the next record, R925 (ff. 238–240), a letter of the Queen on the same marriage.
The writer is not the Queen (“the Queen sends …”, “the Queen desires your Majesty …”) and signs with the number 385. Lasry dates the letter from its content: Montreuil’s mission, and a frost also mentioned in the Hague letter of January on ff. 245–246. He prefers 1646 to 1645. DECODE’s date of 26 June 1646 does not fit the letter’s own “Paris Jan”; the correction is queued for DECODE.
The key has one- and two-digit homophones (A 5, 15, 23, 25; E 2, 11, 22, 26) and a numbered word list starting at 100: 100 all, 101 are, 102 as, 103 at, 108 and, 109 be, 141 for, 173 I, 174 in, 176 -ing. Lasry’s file says the key has no nulls.

76:53:14:13:26:39:30:236, begins Lasry’s “PARIS JAN …”; the second line is almost all word-list numbers (141, 107, 227, 240 …). Image: The National Archives, SP 106/10 f. 235, via DECODE R924.02 Lasry’s decipherment
The plaintext is Lasry’s and is on the DECODE record, quoted here with punctuation added:
PARIS JAN … IT PLEAS YOUR MAJESTY, YOU HAVE SO MUCH <797> <320> HANDS THAT I WILL NOT BEGIN ANOTHER WITH YOU BUT I LAY IT DOWN … FIRST THOUGH YOUR MAJESTY SHALL KNOW YOU ARE OBEYED AND SR H COMPTON IS <487>D … THE TREATY OF MARRIAGE, WHICH IS A THING OF IMPORTANCE ENOUGH WHEN IT SHALL BE <307> <142> TO BE SET AFOOT WITH PORTUGALL …
… FOR WE KNOW NOW THAT MONTREUL HAS BEEN WITH YOU … THE LEVIES NOW IN HAND IN SO GOOD AN ADVANCE THAT WE HAVE GOOD BRING TO HOLD THAT WE SHALL PASSE A BODY OF AOR [5 OR] 6 THOUSAND MEN AS GOOD AS ARE ANY <330> TO BE FOUND … I AM YOUR MAJESTY’S <219> OBEDIENT <SERVANT> <385>
03 The check made here
Lasry’s interlinear file pairs each line of Sofia Pettersson’s transcription with his plaintext. His key was applied group by group to the cipher lines, without his plaintext. Of 2012 groups, 1850 (91.9%) get a value. On 11 lines his plaintext line has a different number of words from the cipher line, so the columns shift and those lines are not compared; on all the others (1604 groups) the key gives exactly his text. The 162 groups with no value are 58 three-digit numbers (85 occurrences; 324 and 428 four times each) and 11 low figures (77 occurrences; 21 alone 24 times), which Lasry writes as “_”. The replay in section 02 shows the first 120 groups of that run.
04 What stays open
- The three-digit numbers that are not in Lasry’s word list, left in brackets in his plaintext. Some are probably words of the list, others names.
- The low figures 21, 30, 42, 50, 16 and a few others, which have no value in the key. They may be word dividers, nulls or letter values missing from the alphabet; this is not settled here.
- Who 385 is. The letter speaks for the Queen’s council at Paris and does not name its writer, but Eric Sams deciphered this letter and the Queen’s (R925) in 1976 for Ian Roy (Archivaria 21, 1985–86, pp. 89–90): the writer is Henry Jermyn, at Paris on 26 January 1646, the day of his letter to Nicholas referring him to the King’s letters on the Portugal embassy. Sams’s solution was never printed; it is said to be in the Bodleian with Roy’s papers.
- Re-reading, 23 October 2026. Lasry’s files were fetched with the project’s DECODE login and the letter decoded afresh from Pettersson’s rows (
R924_reading.md, EnglishR924_en.md). The unvalued low figures are nulls between words; “Ian. 26” and “5 or 6 thousand” are numerals in clear; four codes were valued by sense at every occurrence: 168 hope (Lasry hold), 116 can (Lasry brought), 334 what, 227 new. Counted as holes, those four and the 85 open code tokens leave the letter just under the reading bar: decoded, not read. Sams’s decipherment would settle them.

R924, Paris, January 1646 read in part
A writer at Paris to Charles I against Sir H. Compton's journey and the treaty for Prince Charles's marriage with Portugal, on Montreuil's mission, the frost that stopped the river traffic, and levies of five or six thousand men to send over.
Builds coherent sentences, but under the read bar of 95% of words read as sense (89% here); the holes are marked in the reading.

The writer is Henry Jermyn (Eric Sams, who deciphered this letter and the Queen's of the same key in 1976 for Ian Roy, *Archivaria* 21, 1985-86, p. 89; his solution is not printed). ## Reading Paris, Ian. 26. [207]. It pleas your Majesty, you have so much [797] [320] hands that I will not begin another with you; but I lay it down for the same reason that the [734]s continue theirs, that I am certainly too strong with the reasons which occur on my side, which I will breifly represent to your Majesty. First, though your Majesty should know you are obeyed, and Sr H. Compton is [487]d, that there has been cause for the staying him is [231]; for his [151]ing, I mean for the first [688] to send him, for that I allow to be a good cause for his [?himing]; and that the shame your Majesty mentions for not [487] him is not [?well] layd to there charge, that [?we] have stopped him a while later, but liker to [138] [324]. The opinion for his iourney is that I hope to evidence very clearly to your Majesty [?o]: for the treaty of marriage, which is a thing of importance enough when it should be [307] [142] to be set afoot with Portugall, to passe over the difficulties of [199]ing the first that send an ambassador thither, that treaty can not possibly nether by the rules of reason or [565] bring in question [321] the other with [360] be at [?ani] […], and hitherto for the reasons of the [532] in [685]ation it has not been possible to finish it. For the bringing [?forth] of that [532] is not only by your Majesty's own confession the greatest step that can be [208] to your recovery, all by the [?humble] opinion of all others that [127] at all consider your affaires, ought to receive no interruption, especially since [837]s [783] will declare whither it will bring forth or no. And if this late frost had not suspended all kind of water commerce in the rivers of [?Holland], by this [783] we had seen what might have been relied on the [428] of the [532]. Over the match in [?Holland] will ether be concluded [320] the [466] of the States declaring for you, or the treaty broken off, and your Majesty set at liberty for any new order; which when you are, I should not think that nether a reason for the sending Sr H. Compton. For sure, though he be a very honest man and knowing enough in the things he has been acquainted with, is yet in a very remote incapacity of acquitting himselfe of such a [428] as this according to the dignity of your Majesty's [628]. If this be all [784], the consideration of the marriage is own reason for his iourney; for yet it ought not to be so much as mentioned, and when it shall be treatyd on he ought not to be the person. For all other advantages, I am stil of opinion your Majesty might with much reason have [512]ed them by [193]ing them the hopes of that which only [321] the marriage you can [127] for them [315] by putting them in possession of it. And your Majesty is to consider [502] is the only state from whence they can hope for an ambassador that signifies anything [415] to them; for from all those in [797] with Spaine it is [232], and from the rest they have no hopes of any. Your Majesty's having passed Rubicon [324] unknown to me, receiving of order from them [324] not [?halke] [336] over, and your [688] to send order I [324] your Majesty concerrning Sr H. Compton's iourney to the [428] of the marriage, it is to no end the say anything. Yet only this opinion I will be bold to advance, with great [455]nce, though I love not that presumption: that the hope of the summe of money you mention, and other considerable alliances to your cause from that crown, is the highest delusion in the world. But I will hold your Majesty no later with this discours. The account I should give you of your affaires [158], though I confes the [720]s are [301]n very [189], will shew you, with the note the Queen sends of that has been formerly obtained, that the alliances you have had and are now in [512]ation of are not so inconsiderable as your Majesty seems to [?assume] by the [513]ions you use. And though it be now [189] that the [720]s are [301]n, it will be your Majesty's fault if yet they prove not effectuall; for we know now that Montreul has been with you these [?10] [124]s, and if you have [208] any conclusion will him for the [?Scots] that will enable you to stay for the levies now in hand, in so good an advance that we have good [118] to hope that we should passe a body of 5 or 6 thousand men, as good as are any [?way] to be found, by the beginning of [821]. [382] will presently returne, having now recovered his health, to [685] all things [145] their landing and coniuntion with his [402]; which if a news we [159]d [345] be [784] of an advantage they have had on Fairfax, and a supply put into [521], will subs[…] good [321] these men arrive. The Queen desires your Majesty not to hearken by any [632]s to any [678] that can [208] to the preiudice [286] [382] in the [450] of that [402], for that [?we] disiont all this present [488], which I hope will be of great use to your service. This and what [357] writes I [428] is as much as at this present there is [653] to [778] your Majesty. With all [548] preserve your Majesty. I am your Majesty's much obedient servant [385].

The Queen desires your Majesty not to hearken by any [632]s to any [678] that can [208] to the preiudice [286] [382] in the [450] of that [402], for that [?we] disiont all this present [488], which I hope will be of great use to your service. This and what [357] writes I [428] is as much as at this present there is [653] to [778] your Majesty. With all [548] preserve your Majesty. I am your Majesty's much obedient servant [385].

[207]. May it please your Majesty, you have so much [797] [320] hands that I will not begin another with you; but I lay it down for the same reason that the [734]s continue theirs, that I am certainly too strong in the reasons on my side, which I will briefly put to your Majesty. First, though your Majesty should know that you are obeyed and Sir H. Compton is [487]ed, that there has been cause for keeping him back is [231]; for his [151]ing, I mean the first [688] to send him, I allow that to be a good cause for his [?himing]; and the shame your Majesty mentions for not [487] him is not [?well] laid to their charge, that [?we] stopped him a while longer, but more likely to [138] [324]. The opinion about his journey is one that I hope to show your Majesty very clearly: as for the marriage treaty, a thing of importance enough when it should be [307] [142] to be set on foot with Portugal, to pass over the difficulties of [199]ing the first to send an ambassador there, that treaty cannot possibly, neither by the rules of reason or [565], bring into question [321] the other with [360] be at [?ani] […]; and hitherto, for the reasons of the [532] in [685]ation, it has not been possible to finish it. For the bringing [?forth] of that [532] is not only, by your Majesty's own confession, the greatest step that can be [208] to your recovery, but, in the [?humble] opinion of all others who [127] consider your affairs at all, it ought to suffer no interruption, especially since [837]'s [783] will declare whether it will bring it forth or not. And if this recent frost had not suspended all kinds of water traffic on the rivers of [?Holland], by this [783] we would have seen what could have been relied on in the [428] of the [532]. The match in [?Holland] will either be concluded [320] the [466] of the States declaring for you, or the treaty broken off and your Majesty left free for any new arrangement; and when you are, I should not think that either a reason for sending Sir H. Compton. For surely, though he is a very honest man and knowledgeable enough in the things he has dealt with, he is still very far from being able to acquit himself of such a [428] as this in accordance with the dignity of your Majesty's [628]. If this be all [784], the marriage question is [?one] reason for his journey; and yet it ought not even to be mentioned, and when it is negotiated he ought not to be the man. As for all other advantages, I am still of the opinion that your Majesty might with good reason have [512]ed them by [193]ing them the hopes of what only [321] the marriage you can [127] for them [315] by putting them in possession of it. And your Majesty must consider that [502] is the only state from which they can hope for an ambassador of any significance [415] to them; for from all those in [797] with Spain it is [232], and from the rest they have no hope of any. Your Majesty having crossed the Rubicon [324] without my knowledge, receiving orders from them [324] not [?halke] [336] over, and your [688] to send orders, I [324] your Majesty concerning Sir H. Compton's journey to the [428] of the marriage: it is no use saying anything. Yet this one opinion I will be bold to put forward, with great [455]nce, though I do not like the presumption: that the hope of the sum of money you mention, and of other considerable alliances for your cause from that crown, is the greatest delusion in the world. But I will keep your Majesty no longer with this discourse. The account I should give you of your affairs [158], though I confess the [720]s are [301]n very [189], will show you, with the note the Queen sends of what has been obtained so far, that the alliances you have had and are now [512]ating are not as inconsiderable as your Majesty seems to [?assume] from the [513]ions you use. And though it is now [189] that the [720]s are [301]n, it will be your Majesty's fault if they still do not prove effective; for we now know that Montreuil has been with you these [?10] [124]s, and if you have [208] any agreement with him for the [?Scots], that will let you wait for the levies now in hand, so well advanced that we have good [118] to hope we shall bring over a body of 5 or 6 thousand men, as good as any [?way] to be found, by the beginning of [821]. [382] will soon return, having now recovered his health, to [685] everything [145] their landing and junction with his [402]; which, if the news we [159]ed [345] be [784], of an advantage they have had over Fairfax, and a supply put into [521], will [?subsist] good [321] these men arrive. The Queen asks your Majesty not to listen through any [632]s to any [678] that can [208] to the prejudice [286] [382] in the [450] of that [402], for that [?we] disjoin all this present [488], which I hope will be of great use to your service. This and what [357] writes I [428] is as much as there is at present [653] to [778] your Majesty. With all [548] preserve your Majesty. I am your Majesty's most obedient servant, [385].
