The Bertault–Banne Trial

Reading a Colonial Murder Trial as Documentary Biography

How a sixty-three-page criminal file from the Prévôté de Québec — interrogations, confrontations, a death sentence, an appeal — yields the hardest biographical facts we have for Gillette Banne, and why the record must be read with discipline.

The Challenge

A life that survives only because it ended on a scaffold — nearly every fact about Gillette Banne comes filtered through the machinery of colonial criminal procedure.

In the spring of 1672, Gillette Banne, her husband Jacques Bertault, and their daughter Isabelle were accused of killing Isabelle’s husband, Julien Latouche, at the family farm across the river from Trois-Rivières. The case produced a large, difficult dossier — and the reward for reading it is a biography almost nowhere else recoverable.

Critical Research Obstacles
A sixty-three-page file in 1672 cursive Faded, bled-through judicial hand; four interrogations, three sets of confrontations, cost accounts, and two court levels to untangle.
The dossier is bound partly in reverse The earliest proceedings (Trois-Rivières, 19–20 May) sit at the highest page numbers; the Québec phase sits lower. Chronology must be rebuilt from the dates in the text, not the order of the leaves.
The record resists a tidy calendar The killing is reckoned by day of the week (dimanche, lundy, mardy) and by Jacques’s “mardi 15 jours” — not by stated calendar dates. Any “15 May” is reconstruction, not record.
Secondary retellings smoothed the story A vivid 1985 narrative and its reposts supplied dialogue, motives, and a “Marie” forename with no primary support. Each detail must be traced back to a document or set aside.
Two implements, two roles Neighbours found a bloodied fléau (flail) in the barn; the accused describe wielding a houe (hoe). The retellings collapse the two — inverting the physical evidence.
Why It Matters

This same file is the source for Gillette’s age — the “quarante cinq ans” that corrected a decades-old birth-year error. Reading the trial correctly is therefore the foundation the rest of her documentary biography stands on.

The Breakthrough

Each interrogation opens with a fixed formula — name, age, birthplace, condition, residence. That boilerplate is a vital record in disguise.

The most productive feature of the file is the clerk’s routine. When he records the opening of each interrogation, he captures — incidentally, under oath — exactly the data a genealogist needs.

“…qu’elle se nomme Gillette Banne, aagée de quarante cinq ans Environ, Natifve du bourg d’Argences…”

She names herself Gillette Banne, about forty-five, native of Argences (near Caen).

Two more opening formulas anchor the family. Jacques states he is “âgé de 50 ans environ, natif de Poitou, paroisse des Essarts” Confirmed — a birth year near 1622 and a home parish matching independent sources. Isabelle, examined first on 1 June (fol. 94), gives her age as thirteen; the clerk wrote douze, then corrected it to treize Confirmed.

“…son père lui a fait prendre [Latouche]… sa mère n’y avait pas consenti…”

Isabelle testifies her father forced the marriage; her mother had not consented.

The discipline the record imposes

Isabelle’s trial age (13) is her sworn statement. Her marriage age (~12) is a derived figure — marriage date minus inferred birth year — and must be labelled as derived, never quoted as her words.

The Timeline, as the Documents Give It

reconstructed from day-of-week reckoning  ·  stated in the record

[Sun 15 May] Family crosses to the far-bank farm; a first attempt to poison Latouche fails. reckoned
[Mon 16 May] Latouche is killed in the barn; neighbours hear cries — “ha moy, hélas, au meurtre” — then silence. reckoned
17 May Neighbours find the barn bloodied and a bloodstained flail (fléau) — the crime-scene find, distinct from the hoe named in the confessions.
19 May Information opens at Trois-Rivières before Godefroy de Normanville. Jacques taken; Gillette & Isabelle flee.
20 May Witness examinations; ten-year-old Nicolas interrogated (fol. 119). Gillette & Isabelle captured.
1–3 June Case sent to Québec by the Intendant; interrogations before Chartier; mother–daughter confrontation.
8 June Prévôté sentence: death for all three (Chartier, Rageot).
9 June Sovereign Council appeal (Courcelle); Isabelle spared; execution the same day “à quatre heures.”

The Result

A documented life recovered from a courtroom — and a verdict correctly understood as resting on confession, not eyewitness proof.

The file yields a three-phase arc: a household, a killing, and a public reckoning — each grounded in a dated primary document.

Phase 1 · The Household

A marriage the mother opposed

  • Gillette, ~45, native of Argences; Jacques, ~50, of Poitou
  • Isabelle, 13, married the previous August to Latouche
  • A union Isabelle testified her father forced and her mother refused
Phase 2 · The Killing

Reconstructed from testimony

  • A failed poisoning, then the killing in the barn with a hoe (houe)
  • Neighbours as earwitnesses to Latouche’s cries; son Nicolas (~10) nearby
  • The plot described in the accuseds’ own reported words
Phase 3 · The Reckoning

Two courts, one day apart

  • 8 June: Prévôté sentences all three to death
  • 9 June: Sovereign Council spares Isabelle “ayant esgard à l’aage”
  • Execution the same afternoon; goods confiscated; a will noted in the liasse
Why Isabelle Lived

Her reprieve reads as mercy, but the mechanism is procedural: under the Criminal Ordinance of 1670, a corporal sentence required three judges and the most lenient opinion prevailed, and any sentence heavier than the amende honorable carried an automatic appeal. Her youth gave the appellate court the ground it needed.

What the conviction actually rested on

Colonial capital convictions were meant to rest on two unimpeachable eyewitnesses. This case had none to the killing — the neighbours were earwitnesses; the only near-eyewitness was a ten-year-old. The conviction rested on the accuseds’ confessions plus circumstantial “proximate indications” — the bloodied barn, the flail. Any retelling that implies eyewitness proof misstates the record.

Resolved on the Record
What the complete file settled
The earwitness: one man, two clerks Deposed as Baultier at Trois-Rivières (fol. 118) and named Gauthier at Québec — with both records in hand, a scribal variant across two courts, not two people. Cited as provisionally the same neighbour.
Which sentence is operative A complete chain: the 8 June Prévôté minute (fol. 98), two register copies (fols. 111, 129), the procedural recital (fol. 112), and the 9 June Council arrêt. The argument cites the Council arrêt as operative, the minute as the decision appealed from.
Basis of the conviction Confession plus circumstantial indication, not eyewitness proof — flagged so the point survives every future summary.
Still Genuinely Open
Honest to the record
The will Referenced in the execution notation (“Il y a un testament joint au dossier”) but not yet located among the imaged leaves. Cited as referenced, not located.
Argences baptism No baptismal record for Gillette c. 1626 yet found; the parish registers may not survive.

The biography that began in an interrogation formula closes in a cost ledger — the jailer’s charge for board and lodging, the executioner’s fee for the walk to the scaffold. Read with discipline, even a murder file becomes a life.
