Main article: Military history of the Netherlands during World War II
Like the Belgians, the Netherlands declared neutrality in 1939. In May 1940, the Netherlands was invaded after fierce resistance against the Nazis. Rotterdam and Middelburg were heavily bombed. The Dutch joined the Allies and contributed their surviving naval and armed forces to the defense of East Asia, in particular, the Netherlands East Indies. Until their liberation in 1945, the Dutch fought alongside the Allies around the globe, from the battles in the Pacific to the Battle of Britain. On the islands of Aruba and Curaçao (Netherlands West Indies) a large oil refinery was of major importance for the war effort in Europe, especially after D-day. As a protection, a considerable U.S. military force was stationed on the island.[citation needed]
