Following skirmishes in Majavatn and sabotages in Glomfjord and Malm, conducted by the Norwegian resistance movement, martial law was declared on 6 October 1942 in and around Trondheim, in Nord-Trøndelag and in Grane. In a speech held on the city square of Trondheim, Josef Terboven declared an imminent crackdown on "those who pull the strings". Harald Langhelle was executed as a propitiatory reprisal, together with theatre director Henry Gleditsch and eight other people.
