ルートヴィヒ・ベック
After the German attack on Denmark and Norway, the British refused any further contacts with emissaries of the German military opposition, fearing another Venlo incident. The opposition largely dissolved after the German conquest of France in summer 1940 because Halder no longer dared to stand up against an apparently successful Hitler. It only regained momentum in 1944 when a new generation of younger officers decided to conspire against the ruthless Nazi regime. Leiber remained the point of contact at the Vatican for communications from Colonel-General Ludwig Beck in the lead up to the 1944 July Plot.
