In Operation Doomsday, the British 1st Airborne Division acted as a police and military force during the Allied occupation of Norway in May 1945, immediately after the victory in Europe during the Second World War. The division maintained law and order until the arrival of the remainder of Force 134, the occupation force. During its time in Norway, the division was tasked with supervising the surrender of the German forces in Norway, as well as preventing the sabotage of vital military and civilian facilities.
