The letters
Four despatches of Cornelis Haga, first resident Dutch ambassador at the Ottoman court (1 February, 31 March, 24 April and 4 May 1620), on Hungary, Transylvania and the Spanish truce.
Where
Nationaal Archief, The Hague, States General inv. no. 6894; DECODE R2113 and R2115, catalogued as ciphered with signs said to be zodiacal and alchemistic.
The cipher
A simple substitution whose signs are ordinary Latin letter shapes, with a numeric nomenclator of 116 entries in parentheses.
How it was read
The key sits in the same file and is on DECODE as R2118; it fits at once. The scans are bound out of order (R2115 runs p.3, p.2, p.4, p.1).
What it says
Haga urges the Hungarian Estates to elect and crown a new king and warns that nothing said in the Emperor’s ambassador’s name is to be believed.
Still open
One code and a handful of short cipher words.

01 The records and the key

Inventory number 6894 of the archive of the States General holds Haga’s ciphered despatches from Constantinople. DECODE catalogues four items from it: R2113 (1 February 1620, 3 pp.), R2114 (11 May 1620, 6 pp., marked Decrypted), R2115 (4 May 1620, 4 pp.) and, as a key record, R2118, dated 1620 with the note that the date is fictitious and that the key was probably handed to Haga when he left The Hague. R2113 and R2115 were the catalogue target; R2114 was left alone, being marked Decrypted already.

The key is two sheets. The first carries the alphabet table and the first part of the nomenclator, the second continues the numbered list to 116. The alphabet is a simple substitution in which the cipher signs are themselves letter shapes, so the ciphered words look like an odd Latin hand:

The first half of the key's alphabet table, a to l
The key, DECODE R2118: a–l. a is written φ, b K, c an 8-like sign, d ℓ, e 7, f o, g x, h 9, i an ε-like sign, k ω, l a looped 2. Image: Nationaal Archief, The Hague, key sheet (alphabet a–l), via DECODE R2118.
The second half of the key's alphabet table, n to z
n–z: n is written like t, o as a cross, p as a u-like sign, q 6, r d, s z, t a long ʃ, u/v δ, w m, x B, y λ, z an n-like sign. The cell for m falls outside the photographed sheet. Image: Nationaal Archief, The Hague, key sheet (alphabet n–z), via DECODE R2118.

The nomenclator numbers the Sultan and his officers (1 Sultan Osman, 2 Sultan Mustafa his uncle, 3 the Vizier Azem, 4 the Capitan Bassa, 7 the Mufti, 10 the Janitsaraga), then the provincial Bassas and Beys, the cities of the empire, the Christian and Mahometan princes with their ambassadors, the fleets, and the islands and havens of both sides (93 Cyprus to 116 “de Golff”).

02 Four letters, bound out of order

Neither record is one letter, and neither is in order.

03 31 March 1620: Transylvania, Bohemia, and the Spanish truce

The ciphered spans of the March letter run inside clear Dutch. On Transylvania, Haga reports that the Porte will let the resignation be made in favour of “sijn hoocheijts broeder”, and that the province must stay in good correspondence with Hungary so that it does not fall into the hands of Homonnai “ofte anderen {dependenten van t huijs van Oostenrijck}”. Then his own advice:

Ick oordeel dat het {bij de turcken} meerder reputatie ende estime soude geven {dat de Ongaren regem Bohemiae mede erweelden, ende met} (62) in stricte alliantie verbonden bleven.

Hungary and Bohemia united under one head, the Elector Palatine, would, he writes, let Transylvania deal with the Turks on better terms in the treaties that must follow; a legation from Hungary, Bohemia and the incorporated provinces would be welcome at the Porte. The second half of the letter turns to Spain. A Polish envoy has refused to have his lodging prepared in the usual way, which Haga calls a {bravade}; and

(44) {ende} (45) {arbeiden bij} (4) om tyt te winnen, dat hy provisie {een suspensie van wapenen tusschen de turcken}, ende de {coninckrijcken van Napels} ende {Sicilia} gepractiseert mocht worden … (3) (4) {ende} (7) {vragen mijn} curieuselijck ende ernstelijck {off} (50) geresolveert sijn {de treffves met} (70) {te verlengen}, {vrede} te maecken, ofte {de wapenen} wederom {aen te nemen}, twelck men {hier seer gaerne} soude sien, {om Spangie van weder} zyde te mogen {infesteren}.

That is the Grand Vizier, the Capitan Bassa and the Mufti asking the Dutch ambassador, in the last year of the Twelve Years’ Truce, whether the Republic means to renew it, and saying plainly that the Porte would rather it were broken, so that Spain could be attacked from both sides at once.

04 24 April and May 1620: elect a new king

The April despatch reports the arrival of the envoys of the confederated Bohemian and Hungarian lands, sent from the Easter diet of Pressburg with its resolutions and with the intention of sending a formal legation and making a perpetual peace with the Sultan. They were received without delay, by the Grand Vizier and then by the Sultan, and at that audience the ambassador of the Hungarian Estates (kept back until then, the letter says, by the persuasion of the ambassador of the German Emperor) was admitted with them. The Porte answered that the ambassadors would be welcome and that it was resolved to treat and make friendship with the crown of Hungary, Bohemia and the confederated lands.

R2115 was transcribed in full from the four DECODE photographs on 23 October 2026 and every one of its 43 cipher spans decoded sign by sign with the key (R2115_reading.md, with English; code words given as the key’s words, [?word] a doubtful word). The reading audit of 22 October had classed it decoded, not read, when only parts were transcribed. The advice:

Daer is niet noodiger, als winninge van tijt, ende dat de Ungarische Stenden op het alderdesperaetste tot de electie ende croeninge van een nieu coninck procederen, daer naer [?hier] seer wert verlangt.

Dat alreede aen [den Bassa van Buda] ordre gegeven is, met haer goede correspondentie te houden, ende, is noodich, te assisteren, sonder andere last van hier te becomen.

Dat aen contrarie uijtstrooijinge, die van wegen [des Duytschen Keijsers Ambassadeur] souden mogen geschieden, geen geloof geven, [den opperste Vizir] ende [den Mufti] vermanen [den Prins van Transilvania], dat, sonder langer te wachten, de crone van Ungarie soude aennemen

“Nothing is more necessary than to gain time, and that the Hungarian Estates proceed in all urgency to the election and crowning of a new king, which is much longed for here.” Orders have gone to the Bassa of Buda to keep correspondence with them and help them; nothing put about in the name of the German Emperor’s ambassador is to be believed; and the Grand Vizier and the Mufti exhort the Prince of Transylvania to take the crown of Hungary without waiting longer. Haga also reports that the letter of Bethlen Gábor to the Sultan, printed at Cologne by the Emperor to make the Prince odious, was never written. The closing pages are clear: the Polish ambassador has at last had his licence, the Khan of Tartary is said to have marched into Poland in person, and Ottoman preparations go on but will be slow, since neither Sultan nor Vizier goes in person.

05 Method

The DECODE JSON API gave the metadata for the whole run of records at inventory number 6894, which is how R2118 was found to be the key of the series and R2114 to be marked Decrypted. The fifteen page images were fetched with the account’s session cookie. They are photographed sideways, so every page was rotated and cut into strips of three lines before transcription. The alphabet table was transcribed from the key and tested on the first cipher words of R2113 p.2, which gave arbeiden, tusschen, suspensie and de turcken at once; the two letters were then deciphered in two parallel passes. The key’s cell for m lies outside the photographed sheet, so that letter was recovered from the text: the 4-shaped sign, confirmed by becomen, met, mijn, vermogen, teenemael and geconformeert. The nomenclator values were taken from the key and then checked against the sense of the letters, which confirms (19) Buda, (62) Transylvania, (70) Spain, (3) the Vizier Azem, (4) the Capitan Bassa, (7) the Mufti, (58) the States General and (43) the Emperor’s ambassador.

R2113 pp. 3+2, Haga to the States General, Constantinople, 31 Mar 1620 (p. 1 is the clear close of 1 Feb 1620)

Cornelis Haga, Dutch ambassador at Constantinople, reports that the Porte would let Transylvania be resigned to Bethlen Gábor's brother, that Transylvania must keep good correspondence with Hungary, and that the Turks would think better of the Hungarians if they too elected a king of Bohemia; the Grand Vizier, Capitan Bassa and Mufti press him on whether the States mean to extend the truce with Spain, make peace or take up arms again. No sign-level transcription of the cipher spans exists; the reading gives them deciphered in braces, and the images are on the DECODE record.

# DECODE R2113: Haga, Constantinople, reading

Cipher spans are in {braces}. Codes are written [n]. ? marks an uncertain letter or word. The clear text is a quick reading, not a careful transcription.

## Important: the three images are two letters

- **P1** is all clear text. It is the end of a letter dated *In Constantinople den 1en? februarij 1620* and signed by Haga. It has no cipher.
- **P3 then P2** are a different letter, and P3 comes first. P2 ends with *In Constant. den xxxj martij 1620*, so it is dated **31 March 1620**. P3 ends in mid-sentence ("... niet bijstaen") and P2 begins "dese stadt gearriveert". Both pages are ciphered. Page P3's first page (or pages) is not in the scans.

## P1 (clear, 1 Feb 1620)
In outline: the Tatars/Turks and a tribute or war with Poland ("tot betalinge van een iaerlix tribuyt, of de selve ... in openbaren oorloge met dese machtige monarchia te vallen"); talks with the Emperor's ambassador over important fortresses in Hungary. The Turks promise help to Bethlen, Prince of Transylvania, and to Hungary. The ambassador of the Hungarian Estates had no audience with His Imperial Majesty's [the Sultan's] representatives, "mainly because no one has any advantage from the Turks".

## Summary (modern English)
**1 Feb 1620 (P1):** Haga reports that the Turks are pressing Poland: Poland must either pay a yearly tribute or go to open war with the Ottoman state. He also reports talks with the Emperor's ambassador about Hungarian fortresses, Turkish promises of help to Bethlen Gábor of Transylvania and to Hungary, and the Hungarian Estates' envoy. Nobody gets any real advantage from the Turks.

**31 March 1620 (P3 then P2):**
- On Transylvania and Bohemia, Haga reports:
  - the Porte would accept the resignation of Transylvania in favour of "his Highness's brother", meaning Bethlen's brother;
  - that province must stay in good correspondence with Hungary, so that it does not fall to Homonnai or other dependants of the House of Austria. Haga will watch this as far as he can.
- In his view, the Turks would respect the anti-Habsburg side more if:
  - the Hungarians also elected the King of Bohemia and stayed in strict alliance with [62];
  - Bethlen were compensated by other means for his great services and help to the crown.
  - This would strengthen Transylvania against all foreign powers and against the counter-mines at the Porte.
- If Hungary and Bohemia were united under one wise head (the Elector Palatine), [62] could deal with the Turks in the coming treaties with more standing.
- A legation from Hungary, Bohemia and the incorporated provinces would be welcome at the Porte.
- A Polish envoy arrived but refused to have his lodging prepared in the customary way, which Haga calls a show of bravado against the Dutch side.
- [44] and [45] are working with [4] to gain time and to arrange a suspension of arms between the Turks and the kingdoms of Naples and Sicily. Haga hopes these and other Spanish designs against the Christians will get no hearing. He believes they will not be granted.
- [3] [4] and [7] ask him earnestly whether [50] has decided to extend the truce with [70] (the Twelve Years' Truce with Spain, due to end in 1621), to make peace, or to take up arms again. The Porte would gladly see the last, so as to attack Spain from both sides.

## Codes used
[1] (twice, P3), [3], [4] (twice), [7], [44], [45], [50], [62] (twice), [70].

## Signs that did not fit the key
- **m = 4.** Confirmed by becomen (K78ϯ4 7t), met (47ʃ), mijn (4ɛɛt), vermogen, regem, cum. The "4" inside parentheses is a code.
- **p** is written as a u-like sign, sometimes with a leading ɛ-like stroke (as in suspensie, wapenen, Napels); it is not i+p.
- **f** was doubled in "treffves" (ʃd7ooδ72).
- **Hungary is spelled two ways.** "Ongaren/Ongarie" uses ϯ. P3 line 5 opens with a u/p-like sign ("?ngarie"), which may be a slip.
- **ℓ7tδℓ7d7t** (P2 line 13) is unresolved: read literally it gives "denvderen", perhaps meant for "hinderen".
- **ɛo** (P2 line 10) is unresolved.
- **ϯɛ7d** ("hier"?) in P2 line 21 is uncertain.

# DECODE R2113: Cornelis Haga, Constantinople, to the States General: English translation

Translation (Claude Opus 5.5, 23 Oct 2026) of `R2113_reading.md`. The record holds two letters. P1 is the clear close
of a letter of 1 February 1620; the reading gives it only in outline (it is not transcribed), so only that outline is

in full, as running text, from the line-numbered reading. Words in ⟨ ⟩ were in cipher (braces in the reading). Same
holes: `[n]` a code number not identified, `[?word]` an uncertain word (the reading's ? or (?)), `[...]` and `...`

... and intention of [1] has declared, and besides that [...] that we shall be well content ⟨to let the resignation
to his Highness's brother⟩ take place. It is in all ways necessary that the same province ⟨with Hungary and its⟩
[?joined] ... remain in good correspondence, so that it does not come to fall into the hands ⟨of Homonnai⟩, or other
⟨dependants of the House of Austria⟩, on which the whole business here turns; ⟨I shall help to watch, as far as I am
able⟩.

I judge that it would give more reputation and esteem ⟨among the Turks⟩ ⟨that the Hungarians also elected the King of
Bohemia, and⟩ remained bound in strict alliance ⟨with⟩ [62], ⟨his Highness⟩ being contented and recompensed by some
other means for the great services and ⟨help done to the crown⟩. Such would serve to strengthen ⟨the state of
Transylvania⟩ not only ... all foreign powers, but also the counter-mines ⟨which at this Porte⟩ never ⟨cease⟩
against the same ⟨princes⟩. Moreover, ⟨the crown of Hungary united with the Bohemian under one⟩ [?old] and excellent,
prudent head (a?.. ⟨is of the Elector⟩ Palatine) will, in the new treaties ⟨which⟩ will necessarily have to be made
⟨with the Turks⟩, be able to ⟨proceed⟩ in another way ⟨with reputation [?toward them]⟩ ---- ⟨than⟩ [62] can do, who for
us is interpreted ⟨[?in the interest] of⟩ [1].

R2115, Haga to the States General, Constantinople, 24 Apr and [4-7] May 1620 (two letters; images in the order P3, P4, P2, P1)

Two letters. 24 April: Bohemian and Hungarian commissioners from the Pressburg Easter diet received by the Grand Vizier and the Sultan; in cipher, nothing is more necessary than gaining time and that the Hungarian Estates elect and crown a new king; the letter of Bethlen Gábor printed at Cologne to make him odious is a forgery; Naples too exhausted to help the Emperor. May: Haga has turned the Grand Vizier and the chief lords in favour of the King of Bohemia and of Transylvania; the Porte's letters promise perpetual peace; order given to the Bassa of Buda to assist; the Vizier and Mufti urge Bethlen to accept the crown of Hungary; the honour belongs to the States General alone; the chiaus to the Emperor's ambassador is delayed, 'om het spel in Duijtslant ende Ungaria met sodanigen bulleman te verderven'; Polish ambassador, Cossacks, Tatar invasion of Poland expected.

### Letter of 24 April 1620

High and Mighty, Gracious Lords.

On the [?16th] of this month two Bohemian and Hungarian [?commissioners] arrived here, sent from the Easter diet at
Pressburg on behalf of the confederated lands, bringing letters and reports of all that was treated and decided at that
diet, among other things that they intend to send a formal embassy to this Porte and to make a perpetual peace with
His Imperial Majesty [the Sultan].

[?This] was so welcome that they [?enjoyed] a princely reception and quick introduction both to the Grand Vizier and to
His Majesty, by whom not only these [?commissioners] but also the ambassador of the Estates of Hungary (whom the
persuasion of the German Emperor's ambassador had kept back until now) had public audience on [?…]; and they will
apparently be sent back in all diligence with full satisfaction and the answer that the ambassadors who are destined
here will be welcome, and that the Porte is resolved to treat and make friendship with the Crown of Hungary, Bohemia
and the confederated lands.

Nothing is more necessary than to gain time, and that the Hungarian Estates proceed in all urgency to the election and
crowning of a new king, which is much longed for [?here].

The agent of Transylvania showed me a [?certain] copy of a letter which Prince Bethlen Gábor is supposed to have written
to the Turkish Emperor, which the German Emperor had printed at Cologne and spread throughout Christendom [?in order]
to make [the Prince of Transylvania] odious everywhere.

I have informed myself of it with certainty and found in truth that no such letter was ever written to the Turkish
Emperor, nor were the sword, sceptre and banner mentioned in it sent from here to Prince Bethlen Gábor, before or after
the Hungarian troubles; which I thought it useful that Your High Mightinesses and the other princes and estates (who
have an interest in the preservation of the united lands) should know.

By report of trustworthy and politic persons who lately passed through the Kingdom of Naples and pay [?good] attention
to public affairs, [I am] told that the lands are so exhausted and ruined by the heavy burdens of the continual armament
which the Viceroy has made against the Republic of Venice these [?some] [?years], that hardly any help for the German
Emperor can be raised there.

The Polish ambassador still stays inside, without leaving, apparently awaiting orders from his king. [?Herewith].

Constantinople, 24 April 1620.

### Letter of May 1620

High and Mighty, Gracious Lords.

I find that the practices of the Imperialists to make peace between Spain and these lands [the United Provinces], so
that the King might use all his forces by water and land unhindered against the Evangelical princes in the Empire, our
United Netherlands and the Republic of Venice, will make no headway; to which end I have made such efforts and given
such information everywhere that I have entirely disposed the [?Grand] Vizier (who before seemed to want to favour [the
German Emperor's ambassador]) and all the [?chief lords] at this Porte in favour of the King of Bohemia, of [the Prince
of Transylvania] and of [46], so that the ambassador of Hungary and the envoys mentioned in my last were dispatched in
great haste on the first of this month, with their full satisfaction and letters from the Grand Signior, the Vizier,
the Mufti, the Kahya and the Agha of the Janissaries to the said King, Kingdom and Estates, in particular that their
ambassadors, whom they intend to send to this Porte, will be very welcome and agreeable; that the Porte is resolved to
make a perpetual and firm peace with His Majesty of Bohemia, with him whom the Estates of Hungary shall [?elect] as
their king, and with their confederated lands; acknowledging that the ambassadors may be dispatched to that [?end]
without [?loss] of time, and that as long as they keep friendship with this Porte they need fear no enemies.

That order has already been given to [the Pasha of Buda] to keep good correspondence with them and, if needed, to assist
them without receiving any further charge from here.

That no credence is to be given to contrary rumours which might be spread on behalf of [the German Emperor's
ambassador]; [the Grand Vizier] and [the Mufti] urge [the Prince of Transylvania] to accept the crown of Hungary without
waiting longer, since His Excellency, at my request, [said] he would work for it, that no peace be made with [the German
Emperor's ambassador].

The honour of this resolution belongs to [Their High Mightinesses the States General] alone.

[?With] the said ambassador of Hungary a chiaus has been sent to Prince Bethlen Gábor and the Estates to assure them by
word of mouth of the aforesaid resolution and of His Imperial Majesty's good inclination, and [?to conduct] the
ambassadors here and accompany them back.

On the other hand, the dispatch of the chiaus and of [15] to [the German Emperor's ambassador] is put off from time to
time, although they use great diligence to get an answer; but I hope that through our efforts it will come to nothing
altogether, having well informed [the Grand Vizier] of the practices intended by it, to spoil the game in Germany and
Hungary with such a bogeyman, against the intention of the Turkish Emperor and of His Excellency.

The Polish ambassador has at last obtained licence to come here and be heard, having taken his first lodging with the
Emperor's ambassador; but as the Cossacks again do great damage, tempers are embittered as before, and news is expected
shortly that the King of Tartary has marched in person with all his power and fallen upon Poland.

The preparations for war continue daily, although neither His Majesty nor the Vizier will go in person this summer, as
they intend to do next year.

The preparations at sea are made as usual.

Herewith, High and Mighty, Gracious Lords, I pray the Almighty to bless Your High Mightinesses' prosperous and happy
government more and more, commending myself most humbly to Your High Mightinesses' gracious protection.

Constantinople, [?7] May 1620.

Your High Mightinesses' most humble, faithful servant.
