On 28 March 1938, Henlein secretly visited Berlin to meet Hitler, where it was agreed that Henlein would make demands for autonomy for the Sudetenland that would provide the pretext for a German invasion. Heinlein was informed that Hitler now believed that Italy could hold both Britain and France in check and there was no danger of a German attack on Czechoslovakia causing a wider war. Hitler told Henlein the "question of Czechoslovakia would be before very long" and Henlein's task was to press for autonomy by making demands that the Castle could never give. Henlein promised Hitler "We must make demands that cannot be satisfied". At a second meeting on 29 March 1938 held at the "Auswärtiges Amt"s headquarters on the Wilhelmstrasse attended by Hitler, Henlein, the Foreign Minister Joachim von Ribbentrop and the State Secretary Baron Ernst von Weizsäcker to work out the tactics to be followed, Henlein was told to always come across as moderate even when making extreme demands, not to move too quickly, and above all never to negotiate in good faith with the Castle.
