Case Green

Overview

Case Green was Nazi Germany’s 1938 military plan to destroy Czechoslovakia, revealing that Adolf Hitler’s objective exceeded a negotiated settlement over the Sudetenland.

Current Profile

Hitler instructed commanders to plan for invasion of the whole state and described Czechoslovakia as a future launch platform against Bolshevism. The desired operation was rapid—ideally completed before Britain and France could respond effectively—and therefore joined military planning to a diplomatic strategy of presenting opponents with a fait accompli.

After the May crisis, Hitler hardened his determination that Czechoslovakia should disappear. Wilhelm Keitel then presented the finalized plan whose stated purpose, in the episode’s account, was to smash the state by military action. The plan did not become the route used in September because the crisis moved into Chamberlain’s personal diplomacy and the Munich settlement, but it clarifies the larger objective behind the ethnic grievance.

Key Characteristics

• Plan for destroying the whole Czechoslovak state rather than merely occupying German-speaking districts.
• Designed around speed and a fait accompli before effective external intervention.
• Connected Czechoslovakia’s conquest to later eastern war against Bolshevism.
• Hardened after Hitler interpreted the May crisis as a prestige defeat.
• Operational evidence that Sudeten self-determination rhetoric did not define the intended endpoint.

Evidence

• Whole-state objective: 528. The Nazis’ Road to War: Hitler Prepares to Strike (Part 1) says Hitler ordered plans for invading and eliminating Czechoslovakia.
• Speed and sequencing: 528. The Nazis’ Road to War: Hitler Prepares to Strike (Part 1) links the four-day ideal to a fait-accompli strategy against British and French response.
• Finalized plan: 528. The Nazis’ Road to War: Hitler Prepares to Strike (Part 1) attributes the operational document to Keitel and describes its stated aim as smashing the country by military action.

Qualifications

This page is bounded to one episode’s account of the 1938 plan and does not provide a complete order of battle, planning history, archival assessment, or counterfactual campaign result. Planning demonstrates intent and preparation, not certainty that the operation could have met its timetable or defeated Czech and allied resistance. Exact wording, dates, force requirements, command views, and counterfactual outcomes remain source-scoped.

What Changed

• Created the page to separate Hitler’s whole-state military objective from the public Sudeten minority claim.

Relationships

• Adolf Hitler - leader who ordered and hardened the plan.
• Czechoslovakia - state the plan sought to destroy.
• Konrad Henlein - political proxy whose escalating demands helped preserve a pretext for action.
• Ludwig Beck - army chief who warned against the wider-war risk.
• Munich Agreement (1938) - diplomatic settlement that displaced immediate execution while weakening the target.
