Five batteries, without expanding what the clerk left short

A ranking before the strength return

TEL511 names five of the Army of the James's best batteries and includes a short description of their guns. It precedes the request for strengths and gun styles elsewhere on the leaf. All fifty content cells are accounted for, but the source's small mark after D, its bare 17, and its final comparison word same remain unexpanded.[3]

The visible word best and the recurring unit letters suggest a list. They do not say what is being counted, identify every unit, or recover the time and inner addressee. The short sample offers no warrant for inventing those details from historical expectations.

Established key, newly inspected rows

The working key comes from a surviving source, Stager's Cipher Book No. 1, represented here by the Huntington's mssEC 45, together with previously checked coded-and-clear message pairs. An entry gives unrelated outer words that may stand for the word or phrase written between them. Separate sections cover numbers, times, and other service functions. The project's register records both the public positions and the evidence for how a position was used in traffic.[2]

That distinction matters. Applying this register to a previously unread telegram is a reading by an established key and recorded precedents. It is not recovery of an unknown alphabet or an unknown route. A register entry also cannot be substituted wherever its spelling happens to occur: the same surface can be a name, an ordinary word, or a value from a different table section. The occurrence, not just the spelling, must be checked.

Twenty-six occurrences come from the existing audited register. The public States page supplies Amos as New York once. A second public row supplies Negro as Artillery twice. The full source page is decisive for the latter: the centered Artillery value is shared by the printed alternatives Nuptial and Negro. A preserved early crop was misframed and is not the evidence used to settle that reading.

The remaining coded occurrence is pagans. Its root Pagan means Battery, and the visible plural is applied under a previously audited singular/plural precedent from TEL760. This is a local application to the known root and the actual transmitted ending. It does not create a general right to strip s from every unfamiliar surface.

Source corrections and table collisions

The image reads Sligo, not the volunteer transcript's sligs. The established Sligo entry gives In the. This correction begins with the handwriting; it is not a guessed word added to complete the phrase.

Two occurrences of Perfume require the numeral value 3 rather than the alphabetical-table phrase By the way of. The source's unit and caliber positions, together with the already audited number table, support the numeral use. Both incompatible phrase candidates are explicitly rejected. The different-family Amos meaning Cumberland is also excluded; the current No. 1 States row supplies New York.

D[mark] is a different kind of uncertainty. It is a literal unit-letter cell with a small mark, not a failed cipher lookup. The released reading does not call the mark a ditto sign, turn it into Do, or count it as a decoded punctuation operator.

Every content cell

The fifty cells occupy positions 12–61. Twenty are literal. Of the thirty interpreted occurrences, twenty-six use existing register positions, three use the two public rows described above, and one is the local plural application. The two visible closing cells, R OBrien, are outside this count.

Recovered list

A readable display, adding capitalization and punctuation but not missing words, is:

The display does not turn 17 into 17th, identify what the writer meant by the mark after D, or expand same into a particular gun description. A historically fuller battery roster would be an annotation, not additional ciphertext read here.

Independent confirmation

A separately built audit re-read the source and both public rows, reproduced all fifty cells, checked the two Perfume rejections and the local plural precedent, and reached zero unresolved cipher cells. It confirmed that the full public page, not the misframed crop, supports the shared Artillery value. The saved deliberate-alteration checks all stopped at a producer-manifest prerequisite. They do not show that the intended changes to the reading were tested, and are not counted here as confirmation of the plaintext.

TEL512 immediately follows and requests the strengths and gun styles of the batteries. It establishes a related exchange, but neither TEL512 nor the later TEL513 return supplied a word, ordering decision, or substituted value to this reading. The Amos row was independently inspected for TEL511 even though Problem 85 registered the same public position first.

What is not claimed

The contribution is a complete reading by an established key. The table family was already known. After the separate Amos result had been recorded, this message added only Negro to Artillery to the project's register, increasing its total from 395 to 396. The same public position is not counted twice, and the local plural is not promoted to a new table row.

A missing earlier clear is a bounded finding. The received-ledger comparison covered 4,404 pages and 13,182 one-to-three-page windows. Its best near nomination, mssEC 10 pointers 10293–10294, proved on the source images to be different May 2, 1864 traffic. A further search of 401 local Official Records text files and four public-web queries found unit context but no exact TEL511 list. Those files are text witnesses, not 401 independently published books. Unsearched collections and OCR failures remain outside the result.

Source residue stays visible. But[tl]ers is a heading uncertainty outside the fifty-cell content; D[mark], 17, and same are preserved content. A failed row, plural application, or source reading would reopen the relevant decision. An attributable earlier copy or decipherment would change the priority claim.
