The Gathering Storm — United Kingdom
Winston Churchill at his country estate Chartwell in the 1930s — gathering intelligence on German rearmament while warning Parliament of the Nazi threat, largely ignored by the government.
Churchill spent his 'wilderness years' (1929-1939) at Chartwell, which he purchased in 1922. He received intelligence from Foreign Office officials warning of German rearmament and compiled detailed assessments contradicting government assurances. His warnings were dismissed as warmongering until the Munich Crisis of 1938 proved him right.
