Dreyfus’s alleged espionage link to German intelligence

Dreyfus’s alleged espionage link to German intelligence is the central claim against Alfred Dreyfus, but the evidence presented in the narrative steadily separates accusation from proof. A secret file assembled to support the charge contains circumstantial assertions rather than direct identification, while a later report relayed to Picquart says German officials knew nothing of Dreyfus before his arrest. The contradiction exposes how a supposed foreign connection could persist without confirmation from the very intelligence service said to have employed him—and how prejudice and institutional assertion helped make suspicion appear conclusive.

Origins of the suspicion

As a young instructor, Georges Picquart taught Dreyfus topography at the École Supérieure de Guerre. Picquart recalled him as a thin, pale, solemn student, a married man of means among bachelor officers who were often short of money. Picquart did not welcome his invitations to dinner or to a shooting party, and resented the fact that Dreyfus’s family had remained in German-occupied Alsace and that his money came from Germany. When Dreyfus received a lower mark than he expected, he asked Picquart whether the decision was because he was Jewish. Picquart replied that personal prejudice did not affect his judgment; Dreyfus pointed out that the officer’s choice of the word “scrupulous” seemed to leave the possibility open. Their exchange places the later espionage accusation in a setting where Dreyfus’s Jewish identity and German family connections could already be read as signs of disloyalty.

The accusation was later framed as a matter of military access. A secret file claimed that, while attached to the First Department in the second half of 1893, Dreyfus could reach a safe containing plans of fortifications, including those at Nice, and might have passed them to the German Embassy, which supposedly sent them on to the Italian military attaché. It further stated that he joined the Second Department in early 1894 and that a German spy there had been reported in March. In the court-martial, Major Henry identified the alleged traitor as a man in the Second Department and pointed directly at Dreyfus. Dreyfus, who had been sitting calmly, sprang up in anger and demanded the informer’s name. The accusation was forceful; its source remained unnamed.

A secret file without direct proof

When Picquart examined the secret file, its contents disappointed him. He found no witness or document directly naming Dreyfus as a traitor. Its nearest approach was an initial in the phrase “that lowlife D,” which the file treated as incriminating without establishing that the letter referred to Dreyfus. Picquart also questioned the practical and chronological claims about the fortification plans. Given his knowledge of the First Department’s layout and procedures, secretly removing plans of that size seemed nearly impossible; their absence would have been noticed, and no stolen documents had, to his knowledge, been reported. The file’s account also placed stolen plans in the German attaché’s possession by June, although Dreyfus did not join the First Department until July. These discrepancies turned the dossier from apparent corroboration into a sequence of unverified inferences.

The counter-report from German intelligence

Picquart received a contrasting account from Colonel Foucault, who carefully distanced himself from its source. The information came from Richard Cuers, whom Foucault described as unreliable and whose further story he had not committed to writing. With that qualification made explicit, he reported Cuers’s claim that German intelligence remained angry about the Dreyfus affair—not because France had caught one of its spies, but because Germany had never heard of Dreyfus. Picquart suggested that German officials might still be concealing the truth. Foucault’s answer was that such denial might serve public diplomacy, but continuing it in private, year after year, would make little sense if Germany had actually employed Dreyfus.

Cuers’s reported account supplied a chain of supposed internal inquiries. The Kaiser had personally asked Schlieffen whether the Imperial army had ever employed Dreyfus. Schlieffen then asked Dame, who said he knew nothing of a Jewish spy. On Schlieffen’s orders, Maximilian von Schwartzkoppen was recalled to Berlin for consultation; Cuers claimed to have seen him in the Tiergarten. Schwartzkoppen reportedly said he had first encountered Dreyfus’s name in a newspaper after the arrest. Dame then made discreet inquiries of other friendly European intelligence agencies, which likewise produced no indication that they had employed Dreyfus. This was still secondhand testimony, not independent proof that no contact had ever occurred. Its importance lies in the contradiction it introduced: the institutions supposedly involved in the espionage link were said to deny knowing the accused.

Esterhazy and the unresolved case

The report did not instantly resolve Dreyfus’s guilt for Picquart. It did, however, distinguish the existence of a spy from the identity of the person accused in the original case. Picquart concluded that Major Charles Ferdinand Walsin Esterhazy was spying for a foreign power and selling his country’s secrets. He regarded Esterhazy as an open-and-shut case in fact, though not in law. Dreyfus remained a much larger and more troubling question: finding one spy did not prove that Dreyfus had been another, and the secret file had failed to supply direct evidence that he was.

The contrast also illuminates the unequal standards applied to the two claims. Against Dreyfus, an anonymous allegation, an ambiguous initial, and assumptions about access were treated as a case; against the German account, Picquart and Foucault recognized the need to preserve doubt about a witness they considered unreliable. Meanwhile, at Dreyfus’s public degradation, a Foreign Ministry official reasoned that an innocent man would resist humiliation, and Jean Sandherr answered by declaring Jews inherently without patriotism or honour. The reasoning converted submission into suspicion and identity into supposed evidence. Set beside the secret file’s gaps and Cuers’s reported account, that scene shows how the espionage link could be asserted with confidence even as its factual foundations remained uncertain.
