In early September 1938, President Beneš announced the "Fourth Plan" for constitutional changes to make Czechoslovakia into a federation, which did not meet all of the demands of the Karlsbad programme, but would granted the Sudetenland autonomy. In response to the "Fourth Plan", Henlein announced on 7 September 1938 that he was breaking off all contact with the Castle (i.e. the Czechoslovak government) saying he was not interested in compromise, and the "Fourth Plan" was unacceptable. On 9 September 1938, Benito Mussolini in a speech formally endorsed all 8 points of the Karlsbad programme and denounced Czechoslovakia as a state "tainted" by its alliances with France and the Soviet Union. From 12 September 1938, forward, Henlein helped organise hundreds of terrorist attacks and two coup attempts by the "Sudetendeutsches Freikorps" paramilitary organisation affiliated with the "SS-Totenkopfverbände", immediately after Hitler's threatening speech in Nuremberg at the Nazi Party's annual rally. On 12 September 1938, in his keynote speech at the Nuremberg Party Rally, Hitler finally dropped the demand for autonomy for the Sudetenland and formally demanded that the Sudetenland join Germany. The attempted uprising was quickly suppressed by Czechoslovak forces, whereafter Henlein fled to Germany only to start numerous intrusions into Czechoslovak territory around Asch as a commander of Sudeten German guerilla bands. Henlein's flight into Germany to escape arrest was widely seen as cowardice, and he always very sensitive towards criticism of his actions in September 1938.
