The feat of the German army in advancing more than two hundred miles north up the Osterdal and Gudbrandsdal valleys from Oslo to Trondheim, and at the same time easily holding Trondheim with a small force against Allied attacks from both the north and the south, is certainly a formidable one. The whole seizure of Norway, though aided by the basest treachery, has undoubtedly been a brilliant military performance. After three weeks the British, with all their sea power, have not even been able to take Narvik.
