The letter
An unsigned, undated German report to “E. M.” (Euer Majestät) on Gabriel Bethlen, the peace with the Emperor, money for 24,000 men and the Margrave’s army. The text names the Emperor in the third person, so the addressee is another Majesty; Frederick V is likely, but nothing on the leaf says so.
Where
Bayerische Staatsbibliothek, Munich, Clm 10403 (Collectio Camerariana 53), n. 65, fol. 192–193, MDZ bsb00116451, scans 411–413; only scan 412 carries cipher. Halm (1874) lists it among Bethlen’s letters to the Emperor of May 1624. Not on DECODE.
The cipher
Homophonic two-digit letters, a code of four-digit numbers for words (1410 Herr, 2638 schreiben, 1628 Jenner), doubled letters for short words (ZZ mir, Yy zu), and two single numbers for words (11 = zu, 71 = dz).
How the key was found
From the word-by-word decipherment written above the lines at the time. It is not the family of Johann Casimir to Camerarius and Carl Pawel: at best 2 letters of 20 agree, at any shift from −6 to +6.
What it says
The writer assures “E. M.” that a “worthy lord” has allowed him to write and that, if something comes about, this lord means next January, with help, to pursue the enemy to the utmost.
Still open
Two unglossed runs (13.32 and 27.13.65), and any measurement of the key: there is no held-out part.
Credit
Brice Dudout (Europe chiffrée) transcribed the runs, rebuilt the key and read the unglossed runs by sense, working with Claude Opus 5.5 agents. The decipherment is the clerk’s. The lead (2181) is from Daniel Bourdeau’s sweep.

01 The leaf

Halm’s catalogue of 1874 (p. 123) lists the piece as “Schreiben an den Kaiser s. d. zum Theil in Chiffern”, between letters of Gabriel Bethlen to the Emperor (Kassa, 29 May 1624). The text, however, addresses “E. M.” and speaks of the Emperor as a third party (“von dem Kayser erlangt”), so it is written to another king. The Palatine papers of the collection make Frederick V, King of Bohemia, the likely recipient, but the writer is not named either.

02 The key

The letters are two-digit homophones (a 6, 9, 15; c 8; d 12, 36, 60; e 13, 19; f 14, 20; n 42, 45, 51; r 49; s 50, 56, 59; t 63, 69 …); 27, 32 and 65 occur once each and have no value. Every value comes from a word glossed over the cipher at the time, so the key is taken from the page, not tested against it. No part of the cipher was held out: it is one page, most of it glossed, and no other piece of Clm 10403 uses the same code. The key is therefore not validated.

03 The unglossed runs

Six runs carry no gloss. Three are certain (deciphered from their context): -olgen (the end of verfolgen, split across the line), -liche in der löbliche Herr (c = 8 rests on this context alone) and kü- (the start of künftigen). One is probable, an s (auffs). Two stay unresolved, 13.32 and 27.13.65, because 27, 32 and 65 each occur once. Of the 18 letters of the unglossed runs, 15 are deciphered, 83%, below the 95% bar. The run 62.61.42.36.19.45 decodes wünden (or sünden if 62 is s), probable but of unclear meaning. The normalised German and an English summary are under Full texts.

n. 65 (scan 412): letter runs with their contemporary glosses not prose

An unnamed writer assures 'E. M.' that a 'worthy lord' has allowed him to write and that, if something comes about, this lord means next January, with help, to pursue the enemy to the utmost; the report deals with Gabriel Bethlen, the peace with the Emperor, money for 24,000 men and the Margrave's army.
