In 1942, the Communist Party of Denmark was banned by the German authorities. Communists organized small sabotage cells across the country, formed mainly by veterans who had been part of the volunteer anti-Franco brigades of the Spanish Civil War. However, as arms were scarce, their weapons were often gasoline and matches, and only small-scale operations were carried out.
