His most controversial stunt was in 1935, when he sought to "demonstrate" the Labour Party's attitude towards the existing society. Inspired by an earlier stunt of the Labour Party's youth organisation (AUF), Lange demonstratively stood above a volunteer soaked in pig's blood, lying over a truck, and "threatening" him with a hammer. The stunt led to clashes with AUF activists (Lange eventually broke his jaw), and as Lange's stunt had not been approved by neither the Fatherland League's local branch nor its central leadership, Lange was transferred to Oslo. He then held the position as national leader of the Fatherland League's youth organisation from 1935 to 1936. Lange was considered a great speaker, and his rhetoric changed between being largely gentle or more vulgar. During a 1935 speech, Lange warned against both socialism and Nazism, often alleging the "dictatorial tendencies" he saw in the Labour Party. He in turn criticised Norway for being "ripe for dictatorship," owing to Norwegians having "stopped thinking" and uncritically accepted "supervisory boards, editorials, propaganda and dozy parliamentarians." Lange travelled through most of the country to hold speeches, including Northern Norway. Lange left the Fatherland League at the end of 1938, and joined Landsforeningen Norges Sjøforsvar ("Country Confederation for the Naval Defense of Norway") as its general secretary. The organisation's purpose was to inform about the importance for Norway of the sea, and thus of the Norwegian navy. Lange continued to travel around the country in order to show films and hold speeches. He agitated for strengthening the Norwegian Armed Forces, and increasingly warned against a possible world war, and how Norway could be pulled into it. Lange was dejected that the authorities did not take him seriously, and left-wing activists continued to disturb his meetings. He showed up at the last meeting of the organisation on 6 or 7 April 1940 with a Krag-Jørgensen rifle, telling the audience to "get ready for war," and asking rhetorically when Norway would arm its forces. Lange travelled to the Norwegian Parliament on 8 April 1940, and begged Labour Party MP Torvald Haavardstad to mobilise the Norwegian army. Haavardstad in turn responded that Lange should quit "this hysterical defence talk." Second World War On 9 April 1940, Norway was invaded by Nazi Germany. Part of the background for Lange's predictions about the future war was the letters he sent to several foreign heads of state, including Winston Churchill and
