The German occupation of Oslo in 1940

A minority of Norwegians supported the Nazi occupation. Vidkun Quisling became Minister-President in 1940 - but only with German support. A “Quisling” became a common British term for any traitorous foreign leader. Quisling with Norwegian volunteers on the eastern front in 1942

When the British learnt from the Norwegian Resistance that the Nazi appointed leader Quisling was holding a rally in Oslo it was decided to disrupt events with a low level raid. The new Mosquito aircraft was already demonstrating its capabilities as a low level precision bomber and was the obvious choice for the raid. It was to be the longest distance raid yet undertaken by the aircraft.
