The Hossbach Conference was a secret meeting Adolf Hitler held with senior military and foreign-policy officials at the Reich Chancellery on 5 November 1937. Its record, discovered by Hugh Legat during the Munich crisis, turned a concealed prewar strategy into evidence before Neville Chamberlain: Hitler’s aims extended far beyond the territorial settlement he was then demanding, and the officials who had questioned his plans had since been displaced.

Setting and participants

The conference took place in Berlin at the Reich Chancellery from 4:15 to 8:30 p.m. on 5 November 1937. The memorandum recording it is headed Berlin, 10 November 1937, and identifies Colonel Hossbach, Hitler’s military adjutant, among those present. The other named participants include Hitler, described as Führer and Chancellor; Field Marshal von Blomberg, the War Minister; and Baron von Neurath, the Foreign Minister. The gathering was not presented as a routine cabinet discussion. Hitler said that the subject was so important that other countries would have discussed it in full cabinet, but he had deliberately rejected bringing it before the wider Reich Cabinet. He framed his remarks as the product of long consideration and experience in power, and asked that they be treated, should he die, as a kind of last testament to his political thinking.

That deliberate restriction of access mattered to the conference’s later meaning. The record was not merely an account of public policy: it preserved a strategic exposition Hitler had withheld from the broader government. When Legat encountered it less than eleven months later, the distinction between private intention and public reassurance became central to the warning he and Hartmann brought to Chamberlain.

Hitler’s programme of expansion

Hitler’s argument began with the claim that Germany’s racial community—more than 85 million people—was crowded into the limited habitable space of Europe and therefore had a right to greater living space. The memorandum presents this not as an incidental grievance but as the premise of a policy: preserving and enlarging that community required territorial expansion. Hitler described force as the means by which Germany’s problem could be solved and stated that, if he were still alive, his resolve was to settle it by 1943–45 at the latest.

The record also identified Austria and Czechoslovakia as targets whose incorporation would benefit Germany militarily and politically. Annexation, in this reasoning, would create shorter and better frontiers, free forces for other uses, and allow the formation of as many as twelve new divisions—approximately one for every million inhabitants. The projected gains therefore joined territorial acquisition to military capacity: expansion would not only enlarge the state but improve its position for further action.

This programme gave the document its force in the 1938 crisis. Hitler was then pressing for the Sudeten territory and making claims that implied his demands in Europe were limited. Hartmann’s warning to Chamberlain drew the opposite conclusion from the 1937 record: the incorporation of Austria and Czechoslovakia was only an initial step in a larger war of conquest. The memorandum thus connected the immediate dispute over Czechoslovakia to an earlier strategy that could not be explained as a single, isolated border revision.

Reservations within the regime

The memorandum’s account of the discussion also records resistance, though not an organized opposition in the later sense. Reading between its lines, Legat recognized that Blomberg and Fritsch, the two senior military commanders, and Neurath had expressed concern about whether Hitler’s strategy was practicable. France’s army was too strong, Czechoslovakia’s frontier defences too formidable, and Germany’s motorized divisions too weak. Their objections were grounded in the military risks of the proposed course, not simply in disagreement over its political ends.

By the time Legat read the record, all three men had been removed from their positions and replaced by Keitel, Brauchitsch, and Ribbentrop. The sequence sharpened the document’s significance: the reservations had not constrained Hitler’s programme, and the officials associated with them no longer occupied their former posts. Hartmann used that change as part of his warning, arguing that the military commanders and Foreign Minister who had objected had all been replaced. The record therefore disclosed both an expansionist intention and the weakening of institutional resistance to it.

Discovery during the Munich crisis

The novel brings the 1937 meeting into the 1938 narrative through the document rather than through a separate, dramatized reconstruction of the conference. In Munich, Legat reads the Hossbach Memorandum and stops at the telephone ringing behind him. The movement from the written record to the ongoing diplomacy makes the past immediately consequential: while officials continue their negotiations, Legat has encountered evidence that changes how those negotiations can be understood.

Hartmann then presents the memorandum to Chamberlain as a record of Hitler’s meeting with senior commanders in the previous November, one in which Hitler had explicitly committed himself to war. He explains that a German diplomat gave it to him in strict confidence. Hartmann argues that it proves Hitler is lying when he claims to have no further territorial demands in Europe, warns that a war to gain living space is planned within five years, and urges Chamberlain not to sign the agreement that night. He also contends that if Britain and France stood firm, the Army would move against Hitler to prevent a disastrous war.

Chamberlain acknowledges Hartmann’s courage and sincerity but refuses to let the document determine the immediate decision. He argues that the British and French public could not be expected to fight to deny ethnic Germans the right of self-determination, and insists that his immediate objective is to avert war and seek a lasting peace. He tells Hartmann to return the document to its source. The conference record therefore alters the reader’s understanding of Hitler’s aims without automatically altering the policy pursued in response: its warning is heard, but the pressures of the Munich settlement remain decisive.

Narrative and historical significance

The Hossbach Conference functions as a buried explanation of the crisis rather than as a self-contained scene. Its date—5 November 1937—places the evidence less than eleven months before Legat reads it, while its stated horizon of 1943–45 gives the present emergency a longer and more ominous scale. The strategic calculations about Austria, Czechoslovakia, frontiers, and divisions make Hitler’s ambitions legible as a connected plan, not a sequence of unrelated demands.

The conference also establishes a contrast between what Hitler said in a restricted meeting and the assurances used in public diplomacy. In the story, that contrast reaches Chamberlain in the form of a memorandum carried at grave personal risk by Hartmann. The document can expose the gap between reassurance and intention, but it cannot settle the political question of what Britain and France should do when war appears imminent. Its importance lies in making the stakes unmistakable: the agreement under discussion addresses an immediate territorial crisis, while the record points toward a broader programme of conquest.
