Anticipating German efforts to capture the government, the entire Norwegian parliament (the "Storting"), the royal family, and cabinet hastily evacuated Oslo by train and car to Hamar and then on to Elverum, where an extraordinary session of parliament was called. In large part because of the presence of mind of the parliament's president C. J. Hambro, the "Storting" managed to pass an emergency measure (known as the Elverum Authorization) that gave full authority to the king and his cabinet until the Storting could convene again.
