Meanwhile, the government line hardened, with Communist Party leaders arrested and trade unionists intimidated. On 10 September 1941, Viggo Hansteen and Rolf Wickstrøm were executed and many more imprisoned following the milk strike in Oslo. Hansteen's execution was later seen as a watershed moment, dividing the occupation into its more innocent and more deadly phases. The same year "Statspolitiet" ("the State Police"), abolished in 1937, was reestablished to assist the Gestapo in Norway, and radio sets were confiscated across the country. Though these were all Terboven's decisions, Quisling agreed with them and went on to denounce the government-in-exile as "traitors." As a result of the toughened stance, an informal "ice front" emerged, with "Nasjonal Samling" supporters ostracised from society. Quisling remained convinced this was an anti-German sentiment that would fade away once Berlin had handed power over to "Nasjonal Samling." However, the only concessions he won in 1941 were having the heads of ministries promoted to official ministers of the government and independence for the party secretariat.
