The German invasion of the Netherlands was a military campaign part of Case Yellow, the 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 in the province of Zealand continued to resist the Wehrmacht until 17 May when Germany completed its occupation of the whole country.
The invasion of the Netherlands saw some of the earliest mass paratroop drops, to occupy tactical points and assist the advance of ground troops. The German Luftwaffe used paratroopers in the capture of several airfields in the vicinity of Rotterdam and The Hague, helping to quickly overrun the country and immobilise Dutch forces.
After the devastating bombing of Rotterdam by the Luftwaffe on 14 May, the Germans threatened to bomb other Dutch cities if the Dutch forces refused to surrender. The General Staff knew it could not stop the bombers and ordered the Dutch Army to cease hostilities. The last occupied parts of the Netherlands were liberated in 1945.
