- The telegram
- A telegram of 27 March 1911 from Federico González Garza at El Paso, Texas, to Braulio Hernández at Presidio, Texas; clear Spanish with four coded words.
- Where
- CEHM-Carso, Mexico City, Fondo CMXV (Archivo Federico González Garza), CMXV.15.1420.3-6; ledger entry 1462, which listed it from the CEHM record ("texto en clave"), with no decipherment.
- The cipher
- Five pairs of letters swap in place, in both directions: L–A, N–E, R–I, S–O, T–U.
- How it was deciphered
- With the five pairs of the Hernández key card of the same fonds (CMXV.16.1557.1, scan 16), found and applied by William Echols; the key was not recovered from the ciphertext. The project re-ran the four decryptions and did not see the images or the card.
- What it says
- Did you receive the pills? You should stay there. Villarreal will leave Wednesday or Thursday, taking a cannon. Write back.
- Still open
- No comparison with the images or the card; whether the telegram is in print was not searched here.
- Credit
- The transcription, the key card and the reading are William Echols’s (issue #351), made with GPT-6.1 Sol in Codex. The images were not seen here and are not reproduced.
01 The telegram
A telegram of 27 March 1911 from Federico González Garza at El Paso, Texas, to Braulio Hernández at Presidio, Texas, in the Archivo Federico González Garza (Fondo CMXV) of the CEHM-Carso in Mexico City, CMXV.15.1420.3-6 (two images, front and reverse). It is in clear Spanish with four coded words. The CEHM record calls it “texto en clave” and gives no decipherment, and catalogue 1462, the ledger’s entry for this fonds, listed it with no known decipherment on that record. William Echols read it with GPT-6.1 Sol in Codex and sent the transcription, the key and the reading; the project could not reach the images and worked from his submission.
02 The key
Five pairs of letters swap in place, in both directions: L–A, N–E, R–I, S–O and T–U; every other letter stays as written. The contributor takes the pairs from the Hernández key card of the same fonds, CMXV.16.1557.1, scan 16. The same box holds the card headed “Herrera. Moreno.” (scan 7), with which another telegram of the fonds was deciphered (its own page); that is a different key. The key was not recovered from the ciphertext.
| Coded word | Read with the pairs |
|---|---|
| VRAALIINLA | VILLARREAL |
| OLADIL | SALDRA |
| AANVLEDS | LLEVANDO |
| CLESE | CANON |
Checked here, with an own script: the four coded words (29 letters) decrypt with the five pairs to the words above, as the contributor gives them, and the words fit the clear text around them. The card and the transcription were not compared with the images.
03 The reading
¿Recibió píldoras? Conviene permanezca esa. VILLARREAL SALDRA miércoles ó jueves, LLEVANDO CANON. Escriba. — González Garza
In English: Did you receive the pills? You should stay there. Villarreal will leave Wednesday or Thursday, taking a cannon. Write back. The coded CANON is written without the tilde, and is read as cañón. The contributor gives no background about the people or the pills, and none is added here.
04 What remains uncertain
- The transcription and the key card were not compared with the CEHM images by the project, and no human has repeated the check.
- That the card is the one filed for this correspondence is the contributor’s identification.
- Whether the telegram is already in print (Narváez’s books, the recipients’ papers) was not searched here; the contributor reports none found.
- No statistical validation is recorded: four words are too few for a language-model test.
