Picquart Investigates and Uncovers Esterhazy’s Espionage

Picquart’s investigation into Major Charles Ferdinand Walsin Esterhazy turns a handful of torn papers into a challenge to the French Army’s accepted account of espionage. The reconstructed telegram and letter drafts suggest that Esterhazy supplied military information to German intelligence, but neither had been sent and neither could serve as straightforward legal proof. As Picquart pursues the lead, the inquiry also reveals how easily confidential intelligence can be withheld, leaked, misread, or made to support a case that the underlying documents do not actually establish.

The Petit bleu and a new suspect

The investigation takes a decisive turn when Captain Lauth sorts through papers retrieved from Max von Schwartzkoppen’s waste. Amid white and grey scraps he finds dozens of pale-blue pieces, thicker than ordinary paper. Their color and material identify them as parts of a Petit bleu, a pneumatic telegram card. Lauth spends four or five hours fitting the fragments together, using transparent adhesive to restore a message that is jagged where pieces are missing but still legible.

The message asks for a fuller written explanation of a matter already discussed and says its writer must decide whether to continue an association with the house of R. Its reverse gives the addressee as Major Esterhazy, at 27, rue de la Bienfaisance. Picquart does not recognize the name, but the address and reference to the house of R prompt him to ask Lauth to check whether an Esterhazy serves in the French Army. Lauth confirms that Major Charles Ferdinand Walsin Esterhazy is with the 74th Infantry Regiment. When Picquart connects that regiment’s station at Rouen with the house of R, the scraps point toward another possible traitor.

The material carries clues as well as limits. After months of examining Schwartzkoppen’s notes and drafts, Picquart recognizes that the Petit bleu’s formal, regular handwriting differs from Schwartzkoppen’s and appears deliberately disguised. The message sounds urgent and irritated, as if the relationship between the writer and recipient is in crisis. Yet Picquart reasons that Schwartzkoppen may have destroyed this particular card precisely because sending it through the Paris pneumatic network would have risked exposing the communication. The document thus identifies a possible contact without establishing that Esterhazy ever received it.

From suspicion to covert inquiry

Lauth next reconstructs a draft letter referring to sketches that Esterhazy had previously supplied and indicating that further sketches were not the last. Picquart reads the incomplete document as evidence that Esterhazy had been handing information to the Germans in return for payment from Schwartzkoppen, while a supposed superior in Berlin objected that the intelligence was not worth its price. The gaps in the paper leave details uncertain, and Lauth warns that the material could be a trap. Picquart considers the possibility that Schwartzkoppen might have planted misleading papers after discovering that his waste was being examined, but judges such deliberate deception unlikely given his known recklessness with documents and affairs.

Neither the Petit bleu nor the draft letter, Lauth emphasizes, can justify Esterhazy’s arrest: neither was ever sent. Their source cannot safely be disclosed without exposing the intelligence agent, and a reconstructed paper would invite questions about its origin. Picquart considers whether Lauth might photograph the card and disguise the tears, as had been done with a Dreyfus document. Lauth points out that this card was in roughly forty pieces rather than six, and that its unfranked address side would quickly reveal that it had never entered the mail. Picquart drops the idea, seals both papers in a folder marked Esterhazy, and decides to investigate what other evidence may exist.

He keeps the discovery close rather than alerting the Minister of War or General Gonse. From his window he can see the minister’s office lighted across the garden, but he fears that reporting the find would surrender control of the inquiry before it has begun. A leak could also alert Esterhazy’s family: the surname has standing in central Europe even if the suspected officer serves in an unfashionable regiment in a garrison town. Picquart locks the folder in his safe and asks Lauth to examine the remaining papers for another draft. His caution is not simply procedural; it follows from the danger that the General Staff might take over the investigation or allow information to reach the suspect.

Following the lead to Rouen

Picquart seeks help from Albert Curé, his old comrade, a major in the 74th Infantry Regiment at Rouen. He telegraphs that he will be in the area and asks to visit; Curé replies that he will be delighted. Picquart travels by the Normandy train from Gare Saint-Lazare and goes to the regiment’s barracks. During a walk around the parade ground, Curé warns him to be careful in approaching Esterhazy, describing him as dangerous in every way. The warning gives the suspected officer a human and practical dimension beyond the name on a fragment, while Picquart’s refusal to disclose the purpose of his visit keeps Curé from being drawn into the secret inquiry.

Back in Paris, Picquart initially resists Henry’s offer to assign an officer to the operation. Henry’s caution unsettles him because Picquart can see that he may have let his imagination cast Esterhazy as a traitor on the scale of Dreyfus, although the evidence so far suggests that Esterhazy has done little. Picquart nevertheless refuses to let Henry take over. He asks Felix Gribelin for a list of police agents, then chooses Jean-Alfred Desvernine, a former dragoon lieutenant who had resigned his commission because of gambling debts and since rebuilt his life. Picquart considers that background useful in investigating Esterhazy’s own gambling and dissolute habits.

To keep the meeting out of the office and away from Henry and Lauth, Picquart arranges to meet Desvernine in civilian clothes outside the Louvre. He adopts the familiar signals of clandestine work: a frock coat, bowler hat, red carnation, and copy of Le Figaro. He instructs Desvernine to investigate Esterhazy’s habits and finances, his service with the 74th Infantry in Rouen, and how often he visits the German Embassy. The operation’s secrecy begins to alter Picquart’s own habits: he recognizes that he is trusting fewer people and worries that professional suspicion could distort his judgment.

The evidence problem and the secret file

The Esterhazy inquiry unfolds against the earlier prosecution of Alfred Dreyfus. When Picquart later opens an envelope containing five documents from the secret file used against Dreyfus, the collection’s apparent weight gives way to a striking absence: it contains circumstance and innuendo, but no document or witness directly identifies Dreyfus as a traitor. The nearest approach is an initial, D, in the phrase that lowlife D. Picquart tests the file’s claims against dates and the practical procedures of the General Staff. Dreyfus joined the First Department only in July 1893, while Henry’s account places German possession of stolen plans in June; the alleged removal and return of architectural plans also raises unanswered practical problems.

The secrecy surrounding this file is itself unstable. After learning that its contents have begun to circulate, Picquart lists those who know of it: senior officers and intelligence staff, the seven judges, President Fauré, his doctor Gibert, and Mathieu Dreyfus, with an unknown number of further recipients. He counts at least twenty people before accounting for anyone Mathieu may have told. Photography, telegraphy, railways, and newspaper presses, he recognizes, make the idea of a permanently contained secret implausible. He also suspects that the leak may not persuade Gonse and Raoul le Mouton de Boisdeffre to permit a fuller investigation; it may instead make them panic and tighten their control.

Later, Picquart searches the intelligence archives for Agent Auguste material, retrieving reconstructed correspondence and other papers from the files. Among the records he follows is an April 1894 report by Major Henry about the identity of agent D, who was said to have supplied the Germans and Italians with plans of Nice and other fortifications. Henry’s report identifies not Dreyfus but Jacques Dubois, a printer with access to publicly available plans and no access to classified material; it recommends no further action. Picquart’s discovery that D is Dubois exposes the danger of allowing an initial to carry the force of an accusation. The archival search therefore does more than add another document to the case: it shows how the military record itself can contain the correction that the official story has suppressed.

Consequences and significance

The investigation does not begin with courtroom-ready evidence. It begins with scraps that have been destroyed, reconstructed, and rendered legally vulnerable by the very secrecy that makes them valuable to intelligence work. Picquart’s response is to preserve them, restrict access, and seek independent evidence about Esterhazy rather than force the fragments into a form they cannot honestly sustain. His caution and his determination coexist: he recognizes that suspicion is not proof, yet refuses to let the absence of admissible evidence end the inquiry.

That tension links the pursuit of Esterhazy to the case against Dreyfus. The Petit bleu points toward a new suspect but cannot prove delivery; the secret file points toward Dreyfus but contains no direct identification; and the archive’s account of D identifies Dubois instead. Across these episodes, documents do not speak independently of their provenance, omissions, and custodians. Picquart’s investigation becomes a contest over who may inspect the papers, what conclusions their gaps permit, and whether an institution will follow evidence even when it threatens the judgment the institution has already defended.
