mortally wounded. On 10 April, the final negotiations between the Norwegians and Germans failed after the Norwegian delegates, led by Haakon VII, refused to accept the German demand for recognition of Quisling's new government. The same day, panic broke out in German-occupied Oslo, following rumours of incoming British bombers. In what has since been known as "the panic day" the city's population fled to the surrounding countryside, not returning until late the same evening or the next day. Similar rumours led to mass panic in Egersund and other occupied coastal cities. The origins of the rumours have never been uncovered. On 11 April, the day after the German-Norwegian negotiations had broken down, 19 German bombers attacked Elverum. The two-hour bombing raid left the town centre in ruins and 41 people dead. The same day 11 Luftwaffe bombers also attacked the town of Nybergsund, in an attempt at killing the Norwegian King, Crown Prince Olav and cabinet. One of the final acts of the Norwegian authorities before dispersement was the promotion on 10 April of Otto Ruge to the rank of major general and appointment to Commanding General of the Norwegian Army, responsible for overseeing the resistance to the German invasion. Ruge replaced the 65-year-old General Kristian Laake as Commanding General, the latter having been heavily criticized for what was considered to be passive behaviour during the initial hours of the invasion. Elements in the Norwegian cabinet considered General Laake to be a defeatist. Following the appointment of Ruge the Norwegian attitude became clear, with orders to stop the German advance being issued. With the Germans in control of the largest cities, ports and airfields, as well as most of the arms depots and communication networks, repulsing them outright would be impossible. Ruge instead decided that his only chance lay in playing for time, stalling the Germans until reinforcements from the United Kingdom and France could arrive. On 11 April, after receiving reinforcements in Oslo, General Falkenhorst's offensive began; its goal was to link up Germany's scattered forces before the Norwegians could effectively mobilize or any major Allied intervention could take place. His first task was to secure the Oslofjord area, then to use the 196th and 163rd Infantry Divisions to establish contact with the forces at Trondheim. Ground campaign When the nature of the German invasion became apparent to the British military, it began to make preparations for a counter-attack.
