The Norwegian Campaign was a military operation during World War II that took place in 1940. It involved the Allied forces, primarily the United Kingdom and France, attempting to prevent Nazi Germany from gaining control over Norway. The campaign aimed to secure vital resources, particularly iron ore, and to establish a supply route to the Soviet Union. The campaign began in April 1940 and included several key battles, such as the Battle of Narvik. Despite initial successes, the Allies faced logistical challenges and strong German resistance. By June 1940, the campaign ended with a German victory, leading to the occupation of Norway.
