Adolf Hitler. He asked in a letter what Hitler's plans were with his "Third Reich", and received response from German authorities that "Nazi Germany will triumph on all fronts." Lange had several Jewish friends, and considered their situation to be under such threat in 1939/40 that he thought they should escape before a German invasion of Norway. He managed to reserve 100 seats on the Norwegian America Line for Jews to escape, but none of the seats were taken. Lange and several of his friends from the Fatherland League were eager to join the resistance forces of the Norwegian Campaign, and they set out to Nordmarka on skis on 10 April. Lange had with him a machine gun and 1,000 bullets, but was forced to turn his weapon in when they met other resistance members. He was considered to be "not reliable" on account of his time in the Fatherland League, and he was left to ski back to Oslo. Lange became dejected and bitter as a result of his treatment, and he was left to think that the Labour Party, which he had criticised for not arming the defence before the invasion, had now also taken over control of Nordmarka. Lange was imprisoned at Møllergata 19 in September 1940 for getting into a fight at Theatercaféen with Eyvind Mehle, an associate of Vidkun Quisling.

Lange thereafter grabbed Mehle and threw him through a door twice. Lange refused to apologise to Mehle, and was captured by German police the following day. Lange was imprisoned for four months, and was released in early 1941. His house was searched several times by the Gestapo when he was in prison.

Following his release from prison, Lange assisted resistance members with information work. He thus came under investigation by the police, as he was "known for being an opponent of NS." In 1942 he was captured and imprisoned once more at Møllergata 19 after his house was raided by German police. It was during his times in prison that
