[EX Q]: Question: Was the Colonel who prepared his inexperienced garrison for combat older than the fortress they were at? Passage:Meanwhile, at Oscarsborg Fortress near Drøbak, Colonel Birger Eriksen prepares his undermanned and inexperienced garrison for combat, while receiving reports from the outlying fortresses of incoming German ships. Early on the morning of 9 April, Eriksen spots the German cruiser Blücher entering Drøbak Sound. Despite having received no instructions from Oslo to engage, Eriksen considers the German ship to be hostile and gives the order to fire, and the fortress's guns and torpedo battery sink the Blücher. Prime Minister Nygaardsvold telephones the King, informing him of the impending invasion, and advises him to flee Oslo. The Royal Family boards a train for Hamar, where the Norwegian Parliament convenes to discuss negotiations with Germany. Bräuer meets Oslo's police chief Kristian Welhaven, his intermediary with the Norwegian Cabinet, to reassure them of his desire to negotiate; at the same time, Pohlman receives orders from Berlin to send paratroopers to Hamar to capture the King and the Cabinet. Nasjonal Samling leader Vidkun Quisling proclaims himself Prime Minister over the national radio, and calls upon the Norwegian people to accept the German occupation forces. Bräuer receives instructions from Hitler himself to go directly to the King and convince him to recognise Quisling's government, though Bräuer is convinced that neither Haakon nor the Cabinet will accept this.
