Second Department

The Second Department is the intelligence branch of the War Ministry, responsible for military intelligence and for handling records that become pivotal to the Dreyfus affair. Its place in the bureaucracy gives it both access to a widening body of evidence and the authority to decide who may investigate that evidence. Under Charles-Arthur Gonse, it becomes a contested institution: its files undermine the case against Dreyfus, even as its hierarchy is used to limit the consequences of that discovery.

Identity and Command

Since Napoleon’s time, the War Ministry has been divided into four departments: administration, intelligence, operations and training, and transport. The Second Department handles intelligence; Gonse is identified as its chief and as head of all military intelligence. His position places him within a clear chain of command: the Minister of War gives orders to the Chief of the General Staff, who gives orders to Gonse, who in turn gives orders to subordinate officers.

Gonse’s authority is matched by his intense work habits. He is known for working fourteen-hour days, and Picquart encounters him in the ministry on a Saturday when the corridors are otherwise deserted. The scene introduces the department not as an abstract office but as a working command center, where information and orders move through personal encounters as well as files.

Intelligence, Records, and the Dreyfus Case

The department’s role in the affair begins with the circulation of intelligence claims. Gonse tells Picquart that Colonel Guérin has reported an alleged confession by Dreyfus at the public parade that morning. The report reaches the intelligence chief before Picquart, who is taken by surprise. The episode shows how the department receives and relays claims about the case, even when their reliability has not yet been established.

The secret file illustrates the difference between possessing intelligence and possessing proof. When Picquart opens an envelope containing five documents, he finds a compilation that relies on circumstances and insinuation rather than direct testimony naming Dreyfus as a traitor. Its nearest approach to identifying him is the initial D in a disparaging reference. Picquart also finds the account of stolen fortification plans implausible: the dates conflict with Dreyfus’s assignments, and the suggested removal and return of large plans would have been difficult to carry out unnoticed. The file’s official status therefore exceeds the strength of its contents.

The department’s archives contain evidence that can reverse the meaning of its own records. During a clandestine search of the filing cabinets, Picquart gathers material concerning Agent Auguste, including correspondence associated with intelligence contacts in Berlin and with foreign military and diplomatic representatives. In a cross-referenced report, Hubert-Joseph Henry had already considered who the agent called D might be. The report identifies Jacques Dubois, a printer, as the likely source of publicly available plans and recommends no further action against him. Picquart recognizes the consequence: D is not Dreyfus but Dubois. The archive preserves a finding that contradicts the suspicion attached to Dreyfus, though it has not displaced the established accusation.

Picquart and the Department’s Internal Conflict

Picquart belongs to the Third Department, not the Second, but his investigation brings him into direct contact with Gonse and the intelligence records under the latter’s authority. When Picquart presents the petit bleu, surveillance photographs, and the secret file, Gonse examines the documents methodically. Picquart explains that he had hoped the file would establish Dreyfus’s guilt, but finds nothing that could withstand serious cross-examination. Gonse does not answer by reopening the original case. Instead, he tells Picquart to investigate Esterhazy, if he wishes, but not to bring the bordereau into that inquiry.

That distinction defines the department’s central conflict. Gonse permits a limited investigation while seeking to prevent evidence about Esterhazy from reopening the question of Dreyfus’s conviction. Later, after a leak makes the secret file’s circulation a pressing concern, Picquart counts at least twenty people who know of it: senior military officers and intelligence personnel, the judges, the president, the president’s physician, and Mathieu Dreyfus. The count underscores how difficult the department’s secrecy is to maintain, especially in a world of photography, telegraphy, railways, and newspapers.

Gonse acknowledges that the original investigation was not handled professionally, citing Jean Sandherr’s illness and Armand du Paty de Clam’s conduct, but argues that reopening the case would revive public conflict and tear the country apart. He ultimately turns that appeal into a formal order: Picquart is not to investigate anything connected with Dreyfus or disclose information to anyone unauthorized. The department’s internal hierarchy thus becomes a means of containing inquiry, even after its own chief has admitted serious defects in the original investigation.

Control of the Archive and Institutional Significance

Control over records becomes an explicit question of authority. When Gonse takes the file marked D from Picquart, he checks its contents and announces an administrative change: from then on, Major Henry will bring all Agent Auguste material directly to him. Picquart protests that this material is their most important source. Gonse’s response rests on his position as head of the intelligence department, not on a dispute about the evidence itself. The change redirects access upward and removes Picquart from the chain through which the records had been handled.

The Second Department therefore functions both as an intelligence service and as the institutional setting in which evidence can be preserved, misread, or restricted. Its files contain material that helps show Dreyfus was wrongly implicated, but the discovery does not automatically correct the official account. The same authority that gives the department access to the archive allows its leadership to narrow an investigation, impose secrecy, and centralize custody. In the affair, the decisive question is not merely what the files say, but who is permitted to read them, connect them, and act on what they reveal.
