[1] He continued to work in the field of intelligence gathering and espionage, first for the Black Reichswehr and later for the private Telegraph Union, a company owned by the politician and media mogul Alfred Hugenberg.
Although a confirmed anti-communist and skeptical about the functionality of democracy as a form of government, Bose at that time came to reject National Socialism as a possible cure for the political ailments of Germany on various grounds, not the least of which was his personal detestation of the Nazi Party leader Adolf Hitler, whom he deemed a vulgar rabble-rouser.
Those two were to join a Reich-directorate that was to consist of Papen, former Chancellor Heinrich Brüning, conservative politician Carl Friedrich Goerdeler, the two Nazi leaders and the General Werner Freiherr von Fritsch.
This speech, delivered by Papen but unbeknownst to the public actually written by Jung, was intended to serve as a signal to all opposition forces in Germany to prepare to rise up against National Socialism and simultaneously to enforce the escalation of the tensions between the SA and the Reichswehr, to underline for Hindenburg the thesis presented in the Bose-Tschirschky Dossier.
However, even though the Marburg Speech turned out to be a success – as the American Ambassador to Berlin William Dodd noted in those days the provocative greeting "Heil Marburg" quickly became omnipresent in Germany – the plan by Bose, Jung, and Tschirschky did not come to fruition: The golden opportunity of the situation was thrown away by the tentative attitude of Papen, who could not bring himself to travel to Hindenburg immediately after the success of the speech became obvious, and by the clumsiness of Hindenburg's son, who clumsily spilled the beans about the Bose-Tschirschky Plan to the Army Minister, Blomberg, and his Chief of Staff, Reichenau, who was in league with Heinrich Himmler and Reinhard Heydrich.
In his memoirs Inside the Third Reich, Albert Speer relates how he was ordered to rebuild the Borsig Palace, to transfer the leaders of the Sturmabteilung (SA) in, and to have all Papen's staff out, within twenty-four hours.
