"A Norwegian officer (with the rank of Oberst) who was instrumental in stopping the first wave of Gruppe 5 of the German invasion force outside Oslo. Eriksen was the commander of Oscarsborg Fortress when Nazi Germany attacked Norway in the early hours of 9 April 1940. He gained lasting recognition for ordering the fortress under his command to open fire on the vanguard forces of Operation Weserübung, sinking the 16,000 ton heavy cruiser Blücher."
