What did Iceland do in World War 2?

During World War II, Iceland played a key role in the Battle of the Atlantic. The country was strategically located in the North Atlantic, making it a vital stopover point for Allied ships traveling between North America and Europe. In 1940, the British invaded and occupied Iceland following the country's occupation by Nazi Germany. The occupation was peaceful and Iceland provided valuable assistance to the Allies. In particular, Iceland provided the Allies with access to its ports, which were used for refueling and maintenance of naval vessels. The Allies also built a number of air bases in Iceland, which were used for conducting bombing raids on Germany. In addition, Iceland provided valuable intelligence to the Allies, including information on German ship movements and weather conditions.
