The Bertault–Banne Trial

Reading a Colonial Murder Trial as Documentary Biography

How a criminal file of sixty-three images 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-image 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, 19–21 May) sit at the highest folio stamps; the Québec phase sits lower. Chronology must be rebuilt from the dates in the text, not the order of the leaves.

The stamps count leaves; the scans count sides Folio stamps appear on rectos only — versos carry none. Sixty-three images are thirty-five leaves, and because the file mixes recto-only with recto-plus-verso openings, any numbering that advances one per image drifts, closes, and reopens. Every citation here is read from the stamp on the leaf.

The dates sit at the far end of the file The Québec interrogations reckon by weekday alone, which invites reconstruction. The Trois-Rivières interrogations — at the highest folio stamps, and so read last — give weekday and numeral together, four times over, and every pairing checks against the 1672 calendar. The dates are in the record; they are simply not where a reader arrives first.

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… femme de Jacques Bertault Masson de son mestier…”

She names herself Gillette Banne, about forty-five, native of Argences (near Caen), wife of Jacques Bertault, mason by his trade.

Two more opening formulas anchor the family. Jacques states he is “âgé de 50 ans environ, natif de Poictou, paroisse des Essards” (fol. 97) Confirmed — a birth year near 1622 and a home parish matching independent sources. Isabelle, examined first on the morning of 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 [La Touche] sans son consentement… sa mère n’y avait pas voulu consentir…”

Isabelle testifies her father forced the marriage; her mother had not wished to consent.

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

All dates below are stated in the record. Where the witnesses disagree, the variant is marked.

16 May The family crosses to the far-bank farm with Latouche. That morning the herb goes into his soup and does nothing. Nicolas, aged ten, puts the crossing on Sunday the 15th — the single point the four accounts dispute. variant

17 May An hour after sunset: Latouche has beaten Isabelle “toute en sang”; the parents intervene; he throws Jacques down; Gillette strikes twice with a hoe. The neighbours hear it from across the water. The body is dragged to the river; that night the women recross.

18 May The women flee into the woods at dawn. That evening Jacques is taken at his own house by two soldiers posted there by the sieur de Labadie.

19 May Information at Trois-Rivières, written in the first person by the greffier Séverin Ameau before Godefroy de Normanville, procureur fiscal. Depositions of Baultier, Petit and Bourgainville the same day.

20 May Ten-year-old Nicolas interrogated; Jacques’s first interrogation — he denies everything and calls the blood sturgeon blood; recollements and confrontations of all three witnesses, and of his own son.

21 May Gillette and Isabelle interrogated. Confronted with both accounts, Jacques abandons his denial: he had said nothing, he explains, until his wife had appeared.

31 May – 1 June The Intendant sends the file down to Québec; the procureur fiscal requires fresh examinations; Chartier grants it on 1 June.

1–3 June Interrogations before Chartier — Isabelle, then Jacques, then Gillette; second and third rounds; the poisoning enters the record; mother–daughter confrontation on the third.

7 June Conclusions of the procureur fiscal: death, and trois cens livres. On Isabelle he asks the court not to stop at her “prétendu age de douze à treize ans” and to see her baptismal extract.

8 June Final chamber interrogations. The bench gives its written avis. Prévôté sentence (TL5,D98): death for the parents, a hundred livres, Isabelle to attend. The parents appeal; of the daughter the acte reads “laquelle n’appelloit point.”

9 June Sovereign Council (Courcelle presiding): appel mis au néant — both appeals dismissed. Jacques strangled then broken; the fine cut to sixty livres; Isabelle condemned to the amende honorable and to attend. Executed the same day “à quatre heures de rellevée.”

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, mason by trade
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 the parents to death; Isabelle convicted, not condemned to die
9 June: Sovereign Council dismisses both appeals; Jacques strangled then broken; the fine cut to sixty livres; Isabelle to the amende honorable “ayant esgard à l’aage”
Execution the same afternoon; goods confiscated; a will noted in the liasse

Why Isabelle Lived

Her survival reads as mercy, but the mechanism is procedural — and it begins one court earlier than the retellings allow. The Prévôté did not condemn her to death: the greffier’s acte records “laquelle n’appelloit point” — she did not appeal, having nothing to appeal from. What reached the Sovereign Council was the prosecution’s appel a minima, arguing her sentence too light and asking the court to look past her “prétendu age.” 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 its ground — and the Council used it to refuse the scaffold, not to release her: she was condemned to make the amende honorable herself and then to watch.

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

Which sentence is operative The 8 June Prévôté minute is a separate instrument in a separate fonds, TL5,D98 — foliated 98 in its own right, which is where the collision with the trial file’s fol. 98 comes from. Its third leaf carries the greffier’s acte of appeal. A register engrossment stands at fol. 129 of the trial file; the prosecution’s conclusions at fols. 110v–111. The argument cites the Council arrêt as operative, the minute as the decision appealed from.

What the parents were fined The prosecution demanded trois cens livres; the Prévôté imposed a hundred on all three; the Council reduced it to sixty, the three of them jointly liable, half to the Récollets to pray for Latouche’s soul, the surplus of their goods confiscated to the King with provision for the minor children Nicolas and Jeanne. Three figures, three stages — not a discrepancy between sources.

The earwitness is one man He is deposed as Baultier at Trois-Rivières and named Gauthier at Québec. Both records describe Louis Petit as his beau-frère; both place him in the same three-witness set confronted against Jacques, who names them himself. Same relationship, same role, two clerks. Proven

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.
