Six troublesome occurrences, settled by exact traffic evidence

A report held up by a few words

TEL523 reports the remaining artillery horses, the departure of infantry, a disabled steamer, and travel to Baltimore. Its final reading accounts for all eighty-one payload cells. Reaching that point required resolving six particular occurrences that the first table application left guarded; the general transport story was not enough to settle them.[3]

The clear source mentions stalls and a breakdown off the capes. Those clauses suggest transport trouble before the intervening words can be read, and make guessing unusually tempting. A guessed steamer or a guessed surname would make a smooth paragraph, but it would not explain the exact transmitted forms or their relation to the surviving key.

What the first table application could establish

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.

The first pass established the No. 1 table family across twelve discriminating entries. It applied the checked rows and local plural precedents, but it did not force the remainder into fluent prose. Its six guarded occurrences were Bourse, alby, tulip, Knaves, and two weaseler forms. Their later resolutions are specific evidence additions; the old near-complete report is preserved as the state before those additions, not mistaken for the final verdict.

Exact precedents for the troublesome forms

alby. An independent earlier telegram, TEL412, has The great wagon train will alby; its exact published clear reads The great wagon train will all be. The words on both sides isolate the same fused spelling. This supports all be in TEL523 while preserving source alby. It is one controlled phrase expansion, not permission to split any odd word.[4]

Bourse. The exact coded-and-clear pair for TEL522 ends with a command formula, a signature marker, and Bourse. The published ending supplies T. S. Bowers. Separating the already known command and signature components isolates that terminal name. Only Bourse to T. S. Bowers transfers to TEL523. The rest of TEL522's sentences, orders, and implied answer remain outside the reading.

weaseler, twice. The public root Weasel means Steam, but a root and an apparently convenient er do not prove steamer. TEL617 supplies an exact full-form check: its The weaseler Illinois keeps things back corresponds to the published The steamer Illinois keeps things back. Both TEL523 occurrences have the same medial e, terminal r, and lack of final s. They can therefore use that exact singular form. This does not resolve every contracted or plural Weasel-family spelling elsewhere.

Knaves. The public root Knave names B. F. Butler. An exact earlier pair, TEL288, shows Knaves carrying the same Butler identity without an encoded possessive. The mechanical reading therefore says B. F. Butler Horses. The apostrophe in the readable [B. F. Butler's] is editorial grammar, not an extra cipher rule.

Why Tulip can be a period here

This was the most important failed first reading. The public No. 1 row gives Tulip as Open, with printed ed/ing forms. Applying that row literally produced without fail Open 1. The initially tempting alternative, taking a period from a different cipher-book family, was rejected: the rest of this message already fixed No. 1.

Later exact message pairs supplied a narrower explanation. TEL288 contains three positions where tulip aligns with a period, while TEL597 supplies an independent lexical use meaning open. Those controls distinguish a punctuation use from a word use without replacing the public Open row. TEL523's occurrence is accepted as the local punctuation use between complete clauses. The evidence establishes this occurrence; it is not an unrestricted Tulip-to-Period table entry.

The other controlled forms remain equally limited. Three horse plurals apply an already audited singular/plural precedent to the known roots Spartan and Spafford. Sulphur is a direct public row for Infantry. Perfume uses the numeral 3 in the adjacent Hundred and 50 sequence, with the conflicting main-table phrase rejected.

Every payload occurrence

The final audit divides the eighty-one cells at source positions 10–90 into twenty-five public/root code-bearing occurrences, fifty-four literal or written service-word identities, and the two separately tracked nonregister forms Bourse and alby. This distinction prevents a locally identified name or fused spelling from being counted as a newly recovered public-table row.

Recovered report

With punctuation and capitalization added, and the unencoded possessive marked:

The written service word stop becomes a sentence break only in the readable version. The brackets remain a hard boundary: no encoded apostrophe or possessive ending has been established.

Independent confirmation

The separate cumulative audit re-read the source image, pinned the earlier producer records, replayed all eighty-one cells, and tested the five occurrences still open after alby independently. It checked Bourse's isolated identity, the two competing Tulip roles, the nonpossessive Butler control, and both exact singular weaseler forms. It reproduced the same complete reading with zero unresolved cipher cells.

The audit also checked the boundaries of the borrowed evidence. TEL522 supplies only the terminal Bowers identity. TEL288, TEL412, TEL597, and TEL617 supply only the identified forms or role controls. None supplies an untracked stretch of TEL523's prose. These are known-pair transfers used to finish a reading under an established key, and they are described as such.

What is not claimed

No new cipher system or general suffix rule. The final project register remains at 396 reusable public positions. The Bourse and alby transfers create no public rows; the exact weaseler form creates no universal er rule; and the Butler possessive is editorial. A complete message reading can be a useful result without pretending that those local exceptions reconstruct an entirely new code.

No exhaustive publication negative. The recorded earlier-clear screen covered 4,404 received-ledger pages and 13,182 one-to-three-page windows, the covering Official Records OCR of 124,954 lines, one local Butler OCR of 27,468 lines, and eight quoted web-query forms in two batches. It found no exact or editorial TEL523 clear. Those are the stated text/interface limits, not a proof about every archive or printing. The known clear of related TEL522 is not a clear of this message.

The old difficulties were resolved by new evidence, not erased. The initial Open reading and the six guarded cells remain documented in the base packet. A failed exact-pair alignment, changed source spelling, or invalid role distinction would reopen the affected occurrence. An attributable earlier TEL523 plaintext would change the priority claim.
