The German invasion of the Netherlands, otherwise known as the Battle of the Netherlands, was a military campaign, part of Case Yellow, the Nazi German invasion of the Low Countries and France during World War II. The battle lasted from 10 May 1940 until the surrender of the main Dutch forces on 14 May. Dutch troops under French command in the far southwestern province of Zealand continued to resist the Wehrmacht until 17 May, when Germany completed its occupation of the whole country.
