In May of 1940, the Netherlands was occupied by the Nazi war machine. At that time, the Netherlands had a total area of 33,000 square kilometers, and only approximately nine million people living there. The country was also relatively flat, with little natural features that could contribute to an armed resistance against the Nazis. The Netherlands had a policy of neutrality and had no recent experience with outside invading forces. In addition, Queen Wilhelmina and the Dutch royal family refused to accept the Nazi offer for protection under the Reich and instead fled to London.
