Operation Weserübung was a large-scale military invasion by Nazi Germany.

It targeted the nations of Denmark and Norway during World War II. This operation took place between 9 April and 10 June 1940. The invasion was the opening part of the Norwegian Campaign. Germany wanted to secure its access to vital resources. Specifically, German industry relied on iron ore from Swedish Lapland. Most of this ore moved through the ice-free port of Narvik in Norway. Controlling the Norwegian coast would prevent enemies from blocking these supplies.

The German military used a specific strategy to achieve surprise. Grand-Admiral Erich Raeder, the leader of the German navy, suggested seizing Norway. He argued that occupying the coast would allow German submarines to operate against the Allies. To ensure speed, the Kriegsmarine used fast warships instead of slow merchant ships. This allowed German forces to land at many different locations at once. The plan involved a full army corps. This included a mountain division, an airborne division, and several infantry divisions.

The goal was to capture cities like Oslo, Bergen, and Narvik very quickly.

Several political tensions helped lead to the invasion. In late 1939, Winston Churchill proposed mining Norwegian waters. This plan was called Operation Wilfred. It was meant to force iron ore ships into the open North Sea. The British also planned to occupy northern Norway under Plan R 4. They hoped to use the excuse of helping Finland during the Winter War. Germany used these potential Allied moves as a justification. They claimed their invasion was a preventive maneuver to protect Denmark and Norway from Anglo-French attacks.

Germany also decided to invade Denmark as part of the plan. The Luftwaffe, or German air force, insisted on this to gain fighter bases. Denmark was also a useful staging area for the move into Norway.

The invasion of Denmark was very fast. German troops landed at Gedser and moved north. Paratroopers even made an attack on the Storstrøm Bridge. By 06:00 on 9 April, the Danish government surrendered. This was the shortest military campaign of the war, lasting less than six hours.

The rapid surrender in Denmark had unique results. The German occupation was initially quite lenient. This leniency helped protect many people, including Danish Jews. Because of the early surrender, many Jews were able to flee to neutral Sweden. Out of over 8,000 Jews in Denmark, only 477 were eventually deported. Of those deported, 70 people lost their lives. This was a different experience than many other occupied territories during the war.

Norway presented a much different challenge than Denmark. The geography, location, and climate of Norway were very different.

The German forces had to target many different population centers. These included Oslo, Bergen, Narvik, Tromsø, Trondheim, Kristiansand, and Stavanger. The operation was supported by the X Air Corps. This unit included about 1,000 aircraft of various types. General Nikolaus von Falkenhorst was given command of the ground forces. He was chosen because he had experience with Arctic warfare.

Operation Weserübung showed how important sea control was for modern war. It involved a massive coordination of land, sea, and air forces. Germany used U-boats to support the invasion through Operation Hartmut. Almost all Atlantic submarine operations were stopped to help this mission. The invasion changed the strategic situation in Northern Europe. It demonstrated how quickly a nation could be overwhelmed by a coordinated strike. The campaign in Norway continued for months after the initial landings in April.
